A History of the German Revolution of 1918 19

In 1918 – 19 Imperial Germany experienced a socialist-heavy revolution that, despite some surprising events and even a small socialist republic, would bring a democratic government. The Kaiser was rejected and a new parliament based at Weimar took over. However, Weimar ultimately failed and the question of whether the seeds of that failure began in the revolution if 1918-19 has never been decisively answered. Germany Fractures in World War One Like the other countries of Europe, much of Germany went into World War One believing it would be a short war and a decisive victory for them. But when the western front ground to a stalemate and the eastern front proved no more promising, Germany realized it had entered into a prolonged process it was poorly prepared for. The country began to take the necessary measures to support the war, including mobilizing an enlarged workforce, dedicating more manufacturing to arms and other military supplies, and taking strategic decisions they hoped would give them an advantage. The war went on through the years, and Germany found itself increasingly stretched, so much so it began to fracture. Militarily, the army stayed an effective fighting force until 1918, and widespread disillusion and failures stemming from morale only crept in towards the end, although there were some earlier revolts. But before this, the steps taken in Germany to do everything for the military saw the ‘home front’ experience problems, and there was a marked change in morale from early 1917 onward, with strikes at one point numbering a million workers. Civilians were experiencing food shortages, exacerbated by the failure of the potato crop over the 1916-17 winter. There were also fuel shortages, and deaths from hunger and cold more than doubled over the same winter; flu was widespread and lethal. Infant mortality was also growing considerably, and when this was coupled with the families of the two million dead soldiers and the many millions wounded, you had a populace th at was suffering. In addition, while working days grew longer, inflation was making goods ever more expensive, and ever more unaffordable. The economy was on the verge of collapsing. The discontent among German civilians was not limited to either the working or middle classes, as both felt an increasing hostility to the government. Industrialists were also a popular target, with people convinced they were making millions from the war effort while everyone else suffered. As the war went deep into 1918, and the German offensives failed, the German nation seemed to be on the verge of splitting, even with the enemy still not on German soil. There was pressure from the government, from campaign groups and others to reform a government system that seemed to be failing. Ludendorff sets the Time Bomb Imperial Germany was supposed to be run by the Kaiser, Wilhelm II, aided by a Chancellor. However, over the final years of the war, two military commanders had taken control of Germany: Hindenburg and Ludendorff. By mid-1918 Ludendorff, the man with the practical control suffered both a mental breakdown and a long-feared realization: Germany was going to lose the war. He also knew that if the allies invaded Germany it would have a peace forced on it, and so he took actions which he hoped would bring a gentler peace deal under Woodrow Wilson’s Fourteen Points: he asked for the German Imperial autocracy to be transformed into a constitutional monarchy, keeping the Kaiser but bringing in a new level of effective government. Ludendorff had three reasons for doing this. He believed the democratic governments of Britain, France, and the United States would be more willing to work with a constitutional monarchy than the Kaiserriech, and he believed that the change would head off the social revolt he feared the war’s failure would trigger as blame and anger were redirected. He saw the neutered parliament’s calls for change and feared what they would bring if left unmanaged. But Ludendorff had a third goal, a far more pernicious and costly one. Ludendorff didn’t want the army to take the blame for the war’s failure, nor did he want his high-powered allies to do so either. No, what Ludendorff wanted was to create this new civilian government and make them surrender, to negotiate the peace, so they would be blamed by the German people and the army would still be respected. Unfortunately for Europe in the mid-twentieth century, Ludendorff was entirely successful, starting the myth tha t Germany had been ‘stabbed in the back’, and helping the fall of Weimer and the rise of Hitler. Revolution from Above A strong Red Cross supporter, Prince Max of Baden became chancellor of Germany in October 1918, and Germany restructured its government: for the first time the Kaiser and the Chancellor were made answerable to the parliament, the Reichstag: the Kaiser lost command of the military, and the Chancellor had to explain himself, not to the Kaiser, but parliament. As Ludendorff hoped, this civilian government was negotiating an end to the war. Germany Revolts However, as the news spread across Germany that the war was lost, shock set in, then the anger Ludendorff and others had feared. So many had suffered so much and been told they were so close to victory that many weren’t satisfied with the new system of government. Germany would move swiftly into revolution. Sailors at a naval base near Kiel rebelled on October 29, 1918, and as the government lost control of the situation other major naval bases and ports also fell to revolutionaries. The sailors were angry at what was happening and were trying to prevent the suicide attack some naval commanders had ordered to try and recover some honor. News of these revolts spread, and everywhere it went soldiers, sailors and workers joined them in rebelling. Many set up special, soviet style councils to organize themselves, and Bavaria actually expelled their fossil King Ludwig III and Kurt Eisner declared it a socialist republic. The October reforms were soon being rejected as not enough, both by the revolutionaries and the old order who needed a way to manage events. Max Baden hadn’t wanted to expel the Kaiser and family from the throne, but given that the latter was reluctant to make any other reforms, Baden had no choice, and so it was decided that the Kaiser would be replaced by a left-wing government led by Friedrich Ebert. But the situation at the heart of government was chaos, and first a member of this government - Philipp  Scheidemann – declared that Germany was a republic, and then another called it a Soviet Republic. The Kaiser, already in Belgium, decided to accept military advice that his throne was gone, and he exiled himself to Holland. The Empire was over. Left Wing Germany in Fragments Ebert and Government At the end of 1918, the government looked like it was falling apart, as the SPD was moving from the left to the right in an ever more desperate attempt to gather support, while the USPD pulled out to focus on more extreme reform. The Spartacists Revolt Bolsheviks The Results: The National Constituent Assembly Thanks to Ebert’s leadership and the quelling of extreme socialism, Germany in 1919 was led by a government which had changed at the very top – from an autocracy to a republic – but in which key structures like land ownership, industry and other businesses, the church, the military and the civil service, remained pretty much the same. There was great continuity and not the socialist reforms that the country seemed in a position to carry through, but neither had there been large-scale bloodshed. Ultimately, it can be argued that the revolution in Germany was a lost opportunity for the left, a revolution that lost its way, and that socialism lost a chance to restructure before Germany and the conservative right grew ever more able to dominate. Revolution? Although it is common to refer to these events as a revolution, some historians dislike the term, viewing the 1918-19 as either a partial / failed revolution, or an evolution from the Kaiserreich, which might have taken place gradually if World War One had never occurred. Many Germans who lived through it also thought it was only half a revolution, because while the Kaiser had gone, the socialist state they had wanted was also absent, with the leading socialist party heading up a middle ground. For the next few years, left-wing groups would attempt to push the ‘revolution’ further, but all failed. In doing so, the center allowed the right to remain to crush the left.

Allusions in Brave New World - 1665 Words

Henry Ford served as the inventor for the assembly line. He believed that the idea of independently manufacturing products was too inefficient and cultivated the idea to move the product instead of the people building it. Ford also pioneered technological research in developing products. Ford served as the turning point for technology; introducing and utilizing break-through ideas. Not only did he change how automobiles were manufactured, he changed the way people thought about technology. He made new technologies readily accessible and set the standard for the 20th century. In Aldous Huxley’s Brave New World, Huxley makes Ford the center-point for why the new society was created, the old one was un-happy and inefficient. Replacing God†¦show more content†¦He theorized that the U.S. economy was heavily inefficient and as a result was beginning to slow down. He instituted many new government policies that were built upon this idea. Brave New World demonstrates this eff iciency policy into the society’s main economy. The government controls most enterprises and believes that inefficiencies would slow down the economy. Automation and technology are utilized whenever possible. 8. Leon Trotsky was a Russian communist leader in the early 20th century. His beliefs, called Trotskyism, stated that the working class should have supreme power in government control. Brave New World implements Trotsky’s ideas through social classification with a cast system. Although there is a working class and wealthy class, the majority are working class members. Socialism is also used throughout Brave New World by the distribution of wealth and control. 9. Charles Darwin was the father of evolution and natural selection. Darwin brought about the idea of genetic evolution by theorizing that only the strongest in a population will survive and be able to carry on their genes. Brave New World takes on these ideas by utilizing genetic engineering to ensure that the society members have the best genes and have few DNA imperfections. This ensures that the members of a class will not be able to become stronger than the high class. It also ensures a broad single identity amongst a class’s members.Show MoreRelatedEssay on Brave New World-Allusions1337 Words   |  6 PagesAllusions to the Brave New World 1.

A Student Of Oak Valley Middle School Essay Example For Students

A Student Of Oak Valley Middle School Essay As a former student of Oak Valley Middle School for all three years, I am proud to say that I still hold my Oak Valley Pride. From the beginning of the 6th grade all the way to the end of 8th grade, I remember almost every single teacher I had and the impact they had on me. With being a member of the Track and Field team for all three years, I clearly remember Mr. Howe, Mr. Haren, Mr. Shindorf, and Mrs. Jarvis. Each of these adults pushed me to do my best both in school and in sports. I even have Mr. Howe as my AP Government teacher this senior year. It was because of Mr. Shindorf praising my basketball skills in gym class in eighth grade that pushed me to join the girl’s freshman basketball team in high school. Mr. Haren was also my physical education teacher and taught me to love both working out and eating healthy. Together, all of these athletic coaches made me into the athlete and overall person I am today. Outside of athletics, I remember Mrs. Edsall, who planted the seed that grew into my love for literature today, Mrs. Lukes, who helped me excel in math to become the AP Calculus student I am today, and Mrs. Marshall, the wonderful woman who pushed me to excel in NJHS and has been behind my inspiration of community service and overall positivity in life. Without these teacher, I would not have had the unforgettable experiences that made my middle school life so amazing nor the incredible knowledge each of them placed inside my young mind. As a current student of Lakeland High School, I am a four year Track and Field athlete as well as a member of the National Honor Society, which came from my strong passion of Oak Valley’s NJHS program. Through NHS, I have had many more opportunities to reach out and help my community, whi. . o these individuals and to help those who were pushed down. I still remember the school dance where a girl was getting bullied for coming to the dance in a dress, while everyone else wore their average clothes. I felt terrible for this poor girl and I knew that no one else was going to step up. I not only told an adult of what was going on, but I also went out of my way to comfort her and make her time at the dance something to remember in a positive way. Having this feeling of helping someone else helped spark my innovation to help others in my community to this very day. I can’t even imagine what it would have been to be at a different middle school, but I’m glad I never found out. I knew from day one that Oak Valley is where I belonged, where I learned to believe, and where I became the person I am today. Thank you, Oak Valley, for making me the person I am today.

Implications of Efficient Market Hypothesis †Free Samples to Students

Question: Discuss about the Implications of Efficient Market Hypothesis. Answer: Introduction: It is crucial for an analyst or investor to select the shares for making an investment as various skills and knowledge is required by the analyst to investigate over the risk and return of the company. Usually, two methods are taken into consideration by the analyst to conduct this study which is technical and fundamental analysis. In technical analysis, share prices are analyzed and according to that and other factors, future movement is the share pricing is depicted whereas in fundamental analysis, financial performance of the company is evaluated and macro economic data is also investigated to analyze the future movements in share prices of the company. In technical analysis and fundamental analysis, various tools are used. However the most famous tools which have been used in this paper are moving average and line chart (technical) and PE Multiple and dividend discount model (fundamental). In this report paper, two portfolios have been prepared which includes 10 stocks each. Out of these portfolios, one portfolio has been prepared according to the technical analysis and other one has been prepared according to the fundamental analysis. The stock analysis for making an investment starts by evaluating the companys financial performance and position. Further, historical prices trends of the stock are analyzed to make a better decision about the investment in the stock. Thus, two methods are taken into consideration by the analyst to conduct this study which is technical and fundamental analysis (Schlichting, 2013). These methods are quite crucial to analyze the stock. However, it has been observed that various challenges are there which has been paused by efficient market theories and behavioral finance theories in which the analysis of stock and selection stocks is done. The efficient market hypothesis theory and behavioral finance theory provide an observation about the market (Schlichting, 2013). Even the stock selection by delivering out a complete analysis of fundamental aspects and technical aspects could not be avoided by the possibility of beating when behavioral finance influences persist. The theories of finance and fundamental concepts like Harry Markowitzs modern portfolio theory and Sharpes capital asset pricing model have offered a strong basis to investigate over the selection of the stocks and performance of the stock (Elton, et al., 2009). The above fundamental theories are based on a belief that entire investors act realistically. Further, fundamental theories also assume that the stock market is efficient and always remain similar all the times due to the reason that the entire required information is accessible by all the participants in the market all the times (Elton, et al., 2009). Though, the behavioral finance theory opposes the observation that entire investors are sensible. Further, efficient market hypothesis theory depict that the view of capital markets are always efficient. It must be kept in brain that the models and techniques which has been used in fundamental analysis and technical analyzes are always based on an assumption that the investors are sensible and capital markets are resourceful (Schlichting, 2013). Thus, the conflicts are always existed among the fundamental results and technical results and the behavioral finance results and efficient market theories results. The investors struggle to hit the market by investigating over the stocks which are methodically covering the fundamental and technical aspects, but the EMH states that it is not easy to beat the market (Ackert and Deaves, 2009). Additionally, the behavioral finance concepts states that investors could not always be sensible which depicts that the decisions made by them for buying and selling the stocks could not always be validated on the fundamental analysis and technical analysis. The choice of investors to buy and sale the shares are sometimes affected by behavioral power (Ackert and Deaves, 2009). Such as in the year of 2008 when the global financial crisis has taken place in USA and affected the economy of USA as well as other countries like United Kingdom (UK), China and Australia. The fundamental concepts depicts that the financial crisis of USA in 2008 must have affected the US only, but it left an impression over the entire world. The worldwide capital markets went into gloominess when the global financial crisis has been encountered in the US (Baker and Nofsinger, 2010). The main reason behind this gloominess in all the capital markets and economy was the behavioral influences. It has been observed that when the United States stocks had fell down, the other companys investors such as the UK, Australia and China had also begun to lose their faith and they have started selling their hold stock. And thus the huge selling made the company weak and it directly made an impact over the share price of the company (Baker and Nofsinger, 2010). The behavioral finance mainly affects over the understanding of capital markets, the EMH also offers sight of another side of the capital market. The behavioral finance principle states that investor could not be sensible and the EMH depicts that the capital market could not be unproductive (Kurth, 2013). The EMH theory is based on an idea that the securities prices incorporate entire required information, and thus, it become impossible for investors to take benefit of the information gap and with the help of it, make excessive gains. In other words, the EMH depicts that the investors could not find the securities undervalued or overvalued to make chances to earn more profits. though, the financial fundamental concepts has been established in the CAPM and Gordons growth rate model which provides an idea that the securities could be overvalued or undervalued in the market. Financial fundamental principles depicts that the securities which are trading in the market could not always be traded in their faire value (Kurth, 2013). Rational and methodology: The methodology includes entire framework which helps in selecting the data and analytical equipments to draw a conclusion from the selected information. It is crucial to adopt a suitable methodology for completing the research work in a very effective and efficient manner. In this report the capital market has been taken into consideration, in which the stock has been analyzed, and it has found out that whether the selected stocks would be able to beat the market or not (Phillips and Stawarski, 2016). The selected methodology for this report comprises stock selections two primary methods which are fundamental and technical methods. The fundamental analysis and technical analysis offers different concept which are based on diverse parameters of selecting the stocks (Palicka, 2011). Since, as both methods are based on diverse principles and concepts so, none no method is superior on other. In fact, it could be said that both the methods such as technical and fundamental could be known as each others complementary method. The fundamental analysis outcomes in stocks selection which are quite strong in context of financial performance at the same time the technical analysis focuses over the growth in the prices along with the financial performance of the company which offers them the best basis to choose a good stock (Palicka, 2011). For this report, it has been found that the stock of Keppel Corporation which is financial strong as the return of the company is quite strong (Yahoo finance, 2017). Further, according to the fundamental analysis it has been comprised that the stock named by Courts Asia Limited is quite strong as the return of the equity is 8.83% (Yahoo finance, 2017). Hence, the fundamental analysis over the selection of the stocks would be good in context of the financial performance. At the same time the stocks which have been selected according to the tec hnical analysis would also offer a good return to the shareholders (Palicka, 2011). It has been observed that it is a good choice for the analyst and investors to analyze the stock according to both the methods as due to it, the result would be sensible and it would help the investor to make a better investment. According to the current research, 2 portfolios have been prepared which includes 20 stocks which have been selected according to the fundamental and technical analysis. Fundamental portfolio has been prepared according to the two main tools of fundamental methods which are Dividend discount model and PE multiple methods. In this report, the stock which has been named by great Eastern limited has been taken into consideration for PE multiple model and dividend discount model. PE Multiple Models: The intrinsic value of Great Eastern limited has been applied over the PE multiple models according to the following details: PE Multiple Model Industry PE ratio 23.50 EPS of Great Eastern 0.14 Intrinsic Value 3.29 The intrinsic value of the stock has been depicted in the above given table is SGD 3.29 which is quite higher than the share price of the stock and thus the share price of the company is undervalued. Dividend discount model: Dividend discount model is a tool of fundamental analysis which has been taken into consideration to analyze the intrinsic value of the stock. The intrinsic value of Great Eastern limited has been calculated as below: Dividend Discount Model Dividend expected 0.10 Growth rate 2% Discount rate 5.00% Intrinsic Value 3.34 It has been observed through this model that the intrinsic value of the stock is SGD 3.34 which is depicting that the stock is overvalued as the current market price of the company is quite lower than the intrinsic value of the company. Technical analysis is most common used model. Technical portfolio has been prepared according to the two main tools of technical methods which are line chart and moving average. In this report, the stock which has been named by Frasers Centre point limited has been taken into consideration for Line chart model and moving average model. It has been observed through the above line chart that the trend line which has been shown in the chart depicting that various ups and downs have been faced by the company in context of fluctuations in the share price. Currently the share price of the company is growing up. Thus by relying over the current scenario, it could be said that the investment in this company would be worthy. The moving average analysis has been done over the Frasers Centre point limited and it has been found that the average of the stock price is SGD 1.94. The moving average could be taken as a cut off level which depicts that the price of the stock is according to the level and thus there are quite more chances for the stock price to be enhanced.

( My Father’s House. 2007 ) There was a turning inclination to mistrust authorization. and the Church needed to react. In a rare recognition of current tendencies. Pope John XXIII called a council to re-evaluate the Churches patterns and turn to the pastoral elements that were ignored during Vatican 1. The First Vatican Council was started by Pope Pius IX. in an effort to support Catholic followings from the influences of liberalism. modernness. the Gallic Revolution and the Enlightenment while promoting scriptural literalism and Papal authorization. ( Encyclopaedia Britannica. 2012 ) This period between the First and 2nd council placed great accent on upholding traditional values. beliefs and patterns. During this clip. the priest was seen in a really important visible radiation ; he neer faced the fold whilst executing mass and he ever spoke in Latin. ( Mark Pattison. Church News. 2005 ) There was besides really small engagement of the temporalty. significance that there were no readers or curates. everyone was merely a mere perceiver. Communion was ever received on the lingua in a kneeling place a nd matrimony between Catholics and non-Catholics was frowned upon. ( Mark Pattison. Church News. 2005 ) This was a really conservative and traditional clip. in which the Church was really in-ward thought. However. with turning force per unit area from the secular universe to do the Church to follow a more modern manner of thought. the Pope felt that alterations needed to be made and he decided to keep a Second Vatican Council. The Second Vatican Council expressed regard for the truth and goodness that came with modernisation. ( Patheos. 2012 ) The Pope believed that to maintain that word of God relevant in people’s lives. the Church should germinate with a altering secular society. The council was held at St Peters Basilica in the Vatican under Pope John XXIII. on the 11th of October 1962 and closed under Pope Paul VI on 8 December 1965 and addressed issues such as ecclesiology. Holy Eucharist. spiritual freedom and ecumenism. ( New Catholic Encyclopedia. pg. 563. 1967 ) the clip the council ended. the Church promoted a more broad manner of thought. The construction of the Church had become less hierarchal and the function of the temporalty became more empowering. Readers during mass were introduced. curates of the Eucharist and leading functions in parishes such as liturgical groups. As a consequence of the council. the function of the priest was less important. with greater accent being topographi c point on ‘ministering to the people’ . The priest now faces the fold. speaks in the slang and Communion is now received in the manus while standing. Pope John besides called for the growing of ecumenism. by seeking to unify the different denominations which he called the ‘separated brethren’ and promoted Dignitatis Humanae or spiritual freedom which states that the Church will back up the self-respect of the human spirit. These alterations were made in an effort to maintain the church relevant in a modern universe ; nevertheless this does non intend that every Catholic shifted their paradigms with the Church. At the clip of the council. and even now. there are many people within the Catholic community who believe that the church became excessively broad with the reforms made during the council. In stating that. Pope John’s call for a paradigm displacement within the Church was highly successful. as many of the alterations made as a consequence of the Second Vatican council still act upon our thought to day. The Second Vatican Council was a major paradigm displacement in the Church’s history. and still influences our thought to a important extent today. This is apparent in the manner constructs discussed at the council such as secularism. liberalism ; ecumenism and equality continue to be issues the Church faces today. In Australia. for illustration. 23 % of the population place themselves as following ‘no religion’ . ( Australian Census Bureau. 2011 ) The Church continues to be criticised for being excessively conservative sing issues such as abortion and contraceptive method. in add-on to being criticised for go oning to restrict the function of adult females in the Church. ( National Catholic Reporter. 2009 ) Many people besides remain opposed to ecumenism. believing that Catholicism is the lone Church founded by Jesus Christ and that spiritual autonomy is to be condemned. ( National Catholic Reporter. 2009 ) These are all on-going issue which the Church are being asked to see. and the fact that people continue to discourse the alterations made by the council shows merely how relevant this paradigm displacement is in our modern universe. It can be concluded that the Second Vatican Council has had a enormous influence on the post-modern universe. The Church has undergone a dramatic alteration from the conservative clip of the First Vatican Council. which sought to deter Catholics from prosecuting advanced thoughts of the clip. to the inclusive and broad spirit of Vatican 2. Although there are still those who argue about whether or non the Church went excessively far. the general consensus is that the Second Vatican Council revitalised the Church in a really positive manner. It is difficult to conceive of the Catholic Church marinading any relevancy in today’s universe without the alterations adopted as portion of the Second Vatican Council.

How to Fill Out a Genealogy Pedigree Chart

How to Fill Out a Genealogy Pedigree Chart The two most basic forms used by genealogists to record ancestral information are the pedigree chart and the family group sheet. They help you keep track of what you find on your family in a standard, easy-to-read format - recognized by genealogists around the world. Even if you use your computer to enter information, almost all genealogy software programs will print out or display the information in these standard formats. Pedigree Chart The chart most people begin with is a pedigree chart. This chart begins with you and branches back in time, displaying the line of your direct ancestors. Most pedigree charts cover four generations, including space to include names plus dates and places of birth, marriage, and death for each individual. Larger pedigree charts, sometimes referred to as ancestral charts, are also available with room for more generations, but these are used less often as they generally are larger than the standard 8 1/2 x 11 format. The standard pedigree chart always begins with you, or the individual whose ancestry you are tracing, on the first line - number 1 on the chart. Information on your father (or ancestor #1s father) is entered as number 2 on the chart, while your mother is number 3. The male line follows the upper track, while the female line follows the bottom track. As in an ahnentafel chart, men are assigned even numbers, and the numbers for women are odd. After youve traced your family tree back more than 4 generations, you will need to create additional pedigree charts for each of the individuals included in the fourth generation on your first chart. Each individual will become ancestor #1 on a new chart, with a reference to their number on the original chart so you can easily follow the family through the generations. Each new chart you create will also be given its own individual number (chart #2, chart #3, etc.). For example, your fathers fathers father will be ancestor #8 on the original chart. As you follow his particular family line further back in history, you will need to create a new chart (chart #2), listing him in the #1 position. To make it easy to follow the family from chart to chart you record the numbers of the continuation charts next to each individual in the fourth generation on your original chart. On each new chart you will also include a note referring back to the original chart (Person #1 on this chart is the same as Person #___ on Chart #___). Family Group Sheet The other commonly used form encountered in genealogy is the  family group sheet. Focusing on the family unit, rather than ancestors, the family group sheet includes space for a couple and their children, along with fields to record birth, death, marriage and  burial places  for each. Many family group sheets also include a line to record the name of each childs spouse, as well as a section for comments and source citations. Family Group sheets are an important genealogy tool because they allow room to include information on the children of your ancestors, along with their spouses. These collateral lines often prove important when tracing your  family tree, providing another source of information on your ancestors. When you have difficulty locating a birth record for your own ancestor, for example, you may be able to learn the names of his parents through the birth record of his brother. Family group sheets and pedigree charts work hand in hand. For each marriage included on your Pedigree Chart, you will also complete a Family Group Sheet. The pedigree chart provides an easy at-a-glance look at your family tree, while the family group sheet provides additional details on each generation.

Letter for the Portfolio Essay Example | Topics and Well Written Essays - 250 words

Letter for the Portfolio - Essay Example For someone who just started writing, it was such a distressing experience to scrutinize the work and rationalize effectiveness based on the essential elements in arguing a position. Likewise, the topic of â€Å"A Strong Healthy Economy Versus a Strong Healthy Environment† was also difficult because, as emphasized, both facets seem to manifest similar levels of importance. Concurrently, one found the topic on â€Å"Causes and Effects of Privacy Violation on Social Media and the Internet† most useful due to the preponderance of continued use of social networking sites and the online medium. Thus, there are a wealth of authoritative sources that provided the needed support. I actually learned immensely from these essays; particularly skills in critiquing, in research, and in writing an effectively supported cause and effect; as well as persuasive arguments. I was made assuming a more professional stance in writing by gathering authoritative information that would support and validate the arguments made. Likewise, I learned to observe proper citations and references; as well as the need to abide by grammatical rules in sentence structure, spelling, use of punctuation marks, appropriate choice of vocabulary, and editing.  

The Effects of Autism on a Familys Social Participation From a Fathers Essay

The Effects of Autism on a Familys Social Participation From a Fathers Perspective - Essay Example In this study, the researcher conducted a qualitative investigation regarding the impact that autism has on a family's social participation from the father's perspective. The researcher will explain how using the Person-Environment-Occupation model may both increase levels of social participation and increase the overall wellbeing and mental health of family's of autistic children. The nature of Autism, a complex developmental disorder, remains largely elusive up to the present time. However, there have been myriad advances and discoveries regarding this condition (Rutter, 1999). Compared to other developmental disorders, Autism is being diagnosed at a rapid rate with an annual growth rate between 10 and 17% (Autism Society of America, 2007). This disorder has a prevalence rate in one out of every 150 births and affects approximately 1.5 million Americans (Autism Society of America, 2007). There is both a desire to treat the devastating effects of this disorder and a fascination to understand the nature of social interaction of patients with this condition. Large proportions of autistic patients exhibit differences in sensory processing and motor performance that may affect social participation and day-to-day functioning (Chawarska, Klin, Volkmar, & Powers, 2008, 104). In their research, Domingue, Cutler, & McTarnaghan (2000) found that family members that care for autistic children have been shown to have greater difficulty in developing and sustaining vital social connections both at work and at home. Social activities such as dinners, weekend outings, and vacations are greatly reduced and marital difficulties often arise from the difficulty of effectively supporting their autistic child (Fisman, Wolf, & Noh, 1989). In their 2005 study, Rodrigue, Morgan, and Geffken pointed out that fathers have been largely neglected in previous research of families with autistic children. They found that fathers of children with autism reported frequent use of both wish-fulfilling fantasy and information seeking as coping strategies. In addition to this, fathers with autistic children reported a greater financial impact and disruption of family activities when compared to fathers that did not have children with this disorder (Rodrigue, Morgan, and Geffken, 2005). While the researchers found that fathers adapt reasonably well to the needs of their autistic children, they also noted that autism had a significant impact on the family's social participation from the father's perspective (Rodrigue, Morgan, and Geffken, 2005). Cost of Care Numerous costs are involved in the treatment and care of autistic patients. When calculating the price of treatment, it is necessary to include direct medical, direct non-medical, and lost productivity costs. A complete treatment plan for an individual with autism may cost the public $3.2 million over the patient's lifetime (Moldin & Rubenstein, 2006, p. 476). In addition to this, the combined societal cost to treat all individuals with autism may amount to $35 billion over the pa

History of architecture Essay Example | Topics and Well Written Essays - 250 words - 2

History of architecture - Essay Example The plans did not contain all the elements in the actual buildings, which were requisite of the architectural drawings. The separation between technology and architecture was achieved by the gross structure and physical plants of the sectional drawings. This implies that architecture focused on the structure of a construction while technology handled the rest of the physical plant. The modern practice combines all the technological and structural requirements of buildings by including every aspect in the plans (Banham 14). I think ancient architectural designs were just concentrated on the complete finishing of buildings. This gave the engineers the freedom to add new concepts pertaining to the preference of the home owners. The article indicates that some of the olden features of a building were not included in the plans, but revealed the skills of the builders. This implies that the principles guiding modernists did not apply then and this was risky to the welfare of the home owners. It is evident that the article highlights the milestones that architectural works have surpassed to give modern designs and inspirations (Banham 16). The article also gives examples of ancient architects who inspired designs and plans that contributed to the developments in the

Parent Teacher Behavior

Parent Teacher Behavior The correlation of a good parent and teacher relationship Parents and teachers constitute two of the most important information sources of young childrens social skills. However, Parents and teachers often are very influential adults in childrens lives, and thus they can provide important perspectives and information concerning childrens behavior. Parents are unique compared to other adults in that they often have observed their childrens behavior across time and across diverse situations. It declared that parents often are aware of subtleties in their childrens behavior and are able to observe them in different contexts, and, therefore, they should be included in the assessment of their children. Inclusion of mothers, fathers, and teachers as assessors allows for comparisons regarding their agreement about childrens behavior across situations with consideration of physical location as well as with sensitivity to differential behavioral values. (Mouly, 2000) In research it has been found that teachers benefit from involvement with parents. Teachers who had high involvement with parents indicated that they were more proficient in instructional and professional activities, devoted more time to instruction, and maintained better parent relationships than did teachers who had little contact with parents. As a result of these reciprocal benefits of parent-teacher relationships, others have encouraged the use of home school collaboration programs to help modify childrens academic and social behavior in school. (Slavin, 2005) Parents play an important role in an exceptional childs life and must inform teachers of their special conditions since no two children are alike. (Mouly, 2000) Teachers can be very helpful in supporting a childs treatment once parents inform them about the disorder. Parents can provide information to the teachers and school personnel about their childs medication or other special needs. From here, teachers can provide parents with occasional progress reports. Even if a child is not active at school, teachers should be informed that treatment can improve the childs ability to learn. However, misunderstandings between student, parent and teacher are common, but can be lessened with early communication between parent and teacher. The first contact between parent and teacher should be made before problems arise with the student. Parents can get involved in school activities in many ways, they can assist teachers with class once a week, volunteer to talk to the class on a particular topic, help with field trips or donate supplies for special events or projects. Some techniques that have effectively been used when working with parents of exceptional students are as follows, effective use of home liaisons, teachers who go on visits with home liaisons to enhance communication between school and parents, treating the parents with respect, encouraging their continued assistance with their childs education, and complimenting them on participation in their childs education. Some other suggestions for improvements that could be made are, training parents specifically in their roles in Individual Education Plans and School Evaluation Teams; obtaining through interviews and observations, viewpoints and feelings of parents; communication through media forms (announcements about appropriate meetings); guest speakers for parent meetings who would give in depth training concerning parental rights, early intervention, and transition plans; all teachers should be required to make personal contact with parents even if there is no apparent intervention neede d, this will keep the door of communication open; activities taught at school that would have a parent participation component included at home. It is very important that teachers help the parents of exceptional children to learn their rights. (OCD, 2005) Some of these parents dont know them at all and some only know bits and pieces that seem misconstrued. Teachers are required to have the parents sign their parental rights at all the meetings with the Diagnostician that would be concerning the childs education. It would be helpful for the parents to know and understand what they are signing for them to feel more comfortable. Most parents are kind of scared to sign things that they are unsure about, and then they are tense and unable to really make the best decisions about their child. (Slavin, 2005) In conclusion, I feel that working with parents of exceptional students will cause a mix of emotions. You are required to be on your toes at all times and they expect you to know everything, but as long as you treat them with respect and follow the simple guidelines from this paper, you shouldnt have a problem. You just have to keep in mind that you are teaching their pride and joy exceptionalities and all. References Mouly, G. (2000). Psychology for effective teaching. New York: Holt, Rinehart and Winston.

It’s Time to Toughen the Laws on Teen Drivers :: Argumentative Persuasive Essays

It’s Time to Toughen the Laws on Teen Drivers      Ã‚  Ã‚  Ã‚   Turning sixteen years old in teenagers' lives is an exciting event. It allows them to get a drivers license and is a big step towards adulthood.   With this, it gives them freedom and control over something they have never experienced before.   In most cases, people stress about gangs, drugs, and violence in our communities as a big result of teenage deaths, but the leading causes of accidents today are teenage drivers, especially sixteen and seventeen year olds.   Maria Purdy, an author for "Teen Magazine", writes about statistics with young teenage drivers.   She sites that, "To equal the number of youths killed in motor vehicle crashes in 1995, a plane with 520 people on board would have to crash with no survivors once a month for a full year" (online).   Legislators should pass a law changing the drivers licensing age to eighteen instead of sixteen.   By doing this, it could decrease driving problems we face today.   Ã‚  Ã‚  Ã‚   In most European Countries, teenagers aren't able to earn a license until they are at least seventeen or eighteen years old.   There have been less fatal crashes among teens in these countries because of this.   Cheryl Tevis who wrote an article in the "Successful Farming" magazine, writes about American teenagers compared to other teenagers around the world.   She states that "American teens drive at an earlier age than those in most countries" (online).   This is not surprising to me since there are some states that have allowed teenagers to drive at age fourteen in some circumstances.   Ã‚  Ã‚  Ã‚   For the most part, sixteen and seventeen year olds don't realize the importance and responsibility that comes when getting a drivers license.   They feel it is something to play around with and don't take it seriously.   For instance, immaturity is a cause of being   irresponsible.   Because of this there are many accidents that happen that could have been prevented.   Allan F. Williams, an author for "Public Health Reports" writes about the characteristics all teenagers have in common.   He observes that "Qualities generally associated with immaturity (such as chance taking, testing limits, poor decision-making, overconfidence) are associated with the more risky driving styles characteristic of teenage drivers" (online).   Almost half of the accidents today caused by teenagers were linked to peer pressure and immaturity.   Ã‚  Ã‚  Ã‚   Often, in teenagers' lives, they look towards their friends for advice and guidance rather than their teachers, parents, and others.

Prayer policies between the Christian and Muslim Essay

The Christian and Muslim religions have long argued their religious differences. On the surface, both religions possess similarities. Both religions advocate the worship of a singular God. Both impose obligations and duties on their believers as a means of becoming and staying as an advocate of the religion. Both use prayer as a means of communicating with God. However, when the prayer policies of each religion are contrasted, the differences between the two systems of beliefs can be easily identified—in their concept of prayer, the form of prayer and the rituals that come with it, and the intention of the prayer. A primary distinction in the prayer policies of both religions is their understanding of the concept of â€Å"prayer. † The Muslim religion, or Islam, understands prayer as that which involves a series of very specific rituals. The Islamic principle of salat, which is commonly used to understand the Muslim concept of prayer, signifies a rigid set of prayers that Muslims are expected to perform five times daily (â€Å"Salat: Daily Prayers†). On the other hand, Christians view prayer in a broader sense, in that they see it as a form of mental and emotional attitude. Therefore, their prayer is not limited to a prescribed form. For the Christians, there is no right and wrong way of praying (â€Å"Muslims Ask, Christians Answer†). A glimpse at the form of rituals each religion observes in praying best illustrate this point. In the Muslim religion, ablutions and washing are required before praying. This is in keeping with the belief that only those who are considered to have been purified can communicate with God. A prayer leader known as the Muezzin calls the Muslim faithful to prayer from a portion of a mosque called a Minaret. After calling the faithful to prayer, only the prescribed prayers should be recited. During prayer, proper clothing, as well as the calculated gestures of kneeling and bowing, is imperative. Otherwise, the prayers said are regarded as void, and the believer is required to repeat the entire prayer from the beginning to the end (â€Å"Salat: Daily Prayers†). On the other hand, the Christian religion does not prescribe either form or amount of prayer. No ablutions or washing rituals are needed before a Christian may validly pray to God. Christian texts such as the Holy Bible, offer suggested passages and prayers, but do not require strict compliance. The religion focuses mainly on the believer’s sincerity and not necessarily his words (Schirrmacher 2). Thus, Christians can use various forms of prayer such as dance, music, whether accompanied or not by lyrics, meditation, or through the use of artistic skills such as painting or sculpture. Another distinction in the prayer policies of both religions is the purpose of prayer. Although both Muslim and Christian prayer invokes the aid of an Almighty being, their prayers aim to bring about different goals. The believers of Allah (i. e. , the term Muslims use to call their God), through all their gestures and prayers, intend to manifest their submission with all humility as a servant, both to his Lord, and to his community (Spengler). Thus, intimate names of God cannot be invoked. Muslim believers regard Allah as solely the Creator and cannot be considered as on equal level with the products of His creation (Schirrmacher 2). Christians, on the other hand, aim to commemorate Jesus Christ’s sacrifice through the Eucharist (Spengler). Through prayer, Christians intend to express the intimacy of their relationship with God. Hence, they can address God as â€Å"Father† or â€Å"Abba. † These distinctions in prayer – their concept of prayer, their rituals in praying, and their goals of prayer—illustrate the differentiate prayer policies between the Christian and Muslim religions. While these distinctions set both religions apart, they both worship only one God. They also impose duties and obligations on their believers. Finally, they use prayer to communicate with God.

Deaf Culture essays

Deaf Culture essays Deaf people, like hearing people have their own culture. Not only d they have there own language but a separate culture then hearing people. The deaf culture is very important to the deaf community in this paper I will tell you some examples of this amazing culture. Many people of the hearing community might think of a deaf person as handicapped but if you called a deaf person this, they would be offended. Deaf people do not think of them self as disabled or handicapped. They prefer to call them selfs by this only for social, political, or economical needs. Many hearing people think that deaf people should learn to lip-read and learn how to speak so hearing people can understand them. Deaf people like to think of them selfs as having nothing more then a language barrier, such as we would think for someone who spoke Spanish instead of English. Also phrases such as deaf and dumb and deaf and mute and hearing impaired are considered offensive to many people in the deaf community. Hard of hearing or just Deaf are preferred by most deaf people. There are a few different types of sign language that a deaf person might use. The most common is ASL (American sign language) when signing in ASL you uses a different grammatical structure. Also In ASL you do not sign every word, words like it, the, is, a, an, etc. are not signed. Another language used is Pidgin signing. With Pidgin you leave out the small words and articles but you use the exact word order. Another is exact English; with this you sign every word, and in the same order as you would in spoken English. ASL has existed since late 1700s. French sign language and British sign language existed in Europe before ASL began. A lot of ASL comes from French sign language. When Europeans came here to settle they brought their deaf culture. When speaking to a deaf person, no matter what type of sig...

Cohabitation Essay Example | Topics and Well Written Essays - 2500 words

Cohabitation - Essay Example The leveling of the divorce rate is covering up the instability in the rising rates of cohabitation that is being passed from generation to generation. Cohabitation outside marriage sociologically changes the formation of the family unit. In a cohabitation arrangement, there is no legal commitment on the part of the spouses in regards to property and long-term child care arrangements. Because it leaves the children at risk, and due to religious and moral values, the act of cohabitation often carries a certain amount of social stigma with it. Yet, research has also shown that couples who cohabitate are significantly more likely to get divorced if the cohabitation progresses into marriage. A study by DeMaris and Rao (1992) concluded that "cohabitors have a higher hazard of dissolution at any given time since marriage. [and] cohabitors are estimated to have a hazard of dissolution that is about 46% higher than for noncohabitors" (p.183). The increased rate of divorce among previously cohabitating couples may be a product of an instability in the relationship from the beginning. According to Bumpass, Sweet, and Cherlin (1991), "About 4 0% of cohabiting unions in the United States break up without the couple getting married, and this tends to occur rather quickly. By about one and one-half years, half of cohabiting couples have either married or broken up" (p.917). Whether the cohabitation arrangement dissolves quickly, or ends in divorce after a later marriage, the prospects for a cohabitating couple are significantly worse than for a couple that marries without ever cohabitating. The rates of divorce and cohabitation have been historically measured by the Census Bureau. According to Fitch, Goeken, and Ruggles (2005), "The acronym POSSLQ-"Persons (or Partners) of Opposite Sex Sharing Living Quarters"-was coined by Census Bureau staff in the late 1970s. POSSLQ households-termed "Unmarried Couple Households" by the Census Bureau-are composed of two unrelated adults of the opposite sex (one of whom is the householder) who share a housing unit with or without the presence of children under 15 years old" (p.2). Divorce rates in theUnited States rose sharply in the period of 1960-1980 followed Chart 1: Source (Schoen & Canudus-Romo) by a leveling off period through the year 2000 (See Chart 1). During this same period, the Percentage of Opposite Sex Sharing Living Quarters rates have continued to rise sharply (See Chart 2). Chart 2: Source (Fitch, Goeken, & Ruggles) An interesting aspect of the divorce and cohabitation rates is that as the cohabitation rate was low and remained steady from 1960-1970, the divorce rate rose sharply. However, during the period of 1975-2005, cohabitation rates have risen dramatically, while the divorce rate has remained steady. From a psychological standpoint, it would seem that a relationship that has transgressed from a cohabitation arrangement to a marriage would have a better chance of success. The partners would be familiar with each other's living habits and the commitment to marriage would be based on a well informed couple. As would be expected, cohabitation has a higher dissolution rate than marriage, but this also extends to the couples who have married and now experience a higher divorce rate. Several studies have confirmed that couples who have

In other words, these are drugs which are taken non-medically for the purpose of enjoyment and not because one is sick. Examples of drugs other this category include psychedelic mushrooms, cannabis, barbiturates, opium, amphetamines and heroin. An athlete will feel satisfied if at the completion of the game it turns out that he/she emerged the winner. However, as it is obvious, one cannot be said to have won the race if he/she has not yet taken part in a given completion. It is both the victorious feeling associated with winning and the intense feeling of competition that leaves some athletes with no option but to abuse some certain drugs. When an athlete wins a race, he/she is sure of taking home (to his/her home country) a medal, getting a good

Global Retail and the Transfer of Management Knowledge Case Study

Global Retail and the Transfer of Management Knowledge - Case Study Example There was much friction to be overcome if convenience stores were to be successful in Japan. This was mainly because of the overwhelming presence of small shops in the area. A lot of laws and regulations were put into place to try to protect these small shop owners, such as laws restricting large retailers-such as department stores-from certain activities (Bernstein, 2008). The company was brought to Japan mainly because of Toshifumi Suzuki. The company which he represented, Ito-Yokado, did not support the idea of bringing the convenience store to Japan as a franchise. However, Suzuki did support the idea and claimed that not only could profits be generated by convenience stores, but that the concept could also result in lessened friction between stores of different sizes. The number of small stores in the country was seen to Suzuki as an opportunity rather than a challenge. His idea was to build a franchise system of convenience stores and, in exchange for a cut of their profits, offer them managerial expertise and other guidance. He obtained knowledge from Southland with regards to how to operate a franchising system. Eventually, Suzuki was able to convince Masatoshi Ito to at least look into the idea (Bernstein, 2008). There were quite a few right moves by the company that led to it being such a large success in Japan. The company sent its amateurs for training in the United States. They knew to avoid price competition with supermarkets. They utilized Southland's accounting system. The setup of the store itself was perceived to the Japanese as being foreign, which had an appeal of its own. Ito-Yokado had such a great market power that Seven-Eleven Japan was able to leverage it to acquire wholesalers. The company positioned its stores in urban areas to attract individuals who only wanted a few items and were in a hurry. They carried a broad array of items for sale (Bernstein, 2008). When the model was re-exported to the United States, the Japanese had learned what mistakes to avoid by observing Southland's slow demise. They used some of the techniques that they utilized in their own country in order to make the convenience store change successful in the United States. One of the biggest keys to doing this was through adapting the latest in information technology. Since that concept had been so successful in Japan, the Japanese figured it could only do the same for the United States. In conclusion, this was a relatively unforeseen event-at least of its scope-in Japanese history. Japanese companies in the retailing industries were not seen worldwide as being efficient. Their distribution systems were archaic at best, and large retail giants such as Wal-Mart were few and far between. Using the skills they learned from Southland and their own parent company, Seven-Eleven Japan was very successful (Bernstein, 2008). Why did 7-Eleven thrive while Southland declined and eventually went bankrupt' Why, more in general, are there so many successful global retailers of non-US origin' 7-Eleven thrived not only because of the reasons discussed above, but also because of several other key factors. These include its franchise system and market dominance strategy, the rationalization

Chili’s Bar Essay Example for Free

Chili’s Bar Essay In the decision making process, it helps to look at all the information. This SWOT is comparing Chili’s restaurant to two of its competitors, Ruby Tuesday’s and Applebee’s. Company History Chili’s restaurants are part of the company, Brinker International Corporation. Chili’s Bar Grill is a casual dining restaurant that was founded in 1975 and has expanded to include 1,200 restaurants located domestically and internationally. There menu consists of fresh and healthy American dishes and limited amount of southwestern style Mexican dishes. In the last 30 years, Chili’s has created an identifiable, recognizable brand name, just think of the commercials. Chili’s Strengths Chili’s is the one of the largest full service restaurant chains with over 1,200 stores, second only to Applebee’s which has about 1,900 stores. Their competitor Ruby Tuesday has less than 900 stores with many of those franchises. Chili’s is part of Brinker Intl. , which is world’s second largest casual dining restaurant operator, the first being Darden restaurants. This allows them to offer affordable prices, because they can negotiate product rates for all of their stores, unlike a smaller company. They have also expanded their company to include Chili’s Too, Small Town Chili’s, and offer catering services. They update their menu one to two times a year, unlike Ruby Tuesday’s which updates their menu every three to four months. Chili’s has a popular menu that keeps people coming back, so they tweak it a bit to keep up with trends, but keep their core items. At this time they serve the same menu in every store, which allows for consistency throughout the company. They have a very broad market with a recognizable brand name and they focus on customer satisfaction. The restaurant business can be very competitive, but they have unusually high management retention and that may be in part to extremely competitive starting salaries and excellent benefit packages. Their competitor, Ruby Tuesday, has franchised many of its stores, creating varied salaries, salary caps, and benefits, when going from a franchise to a corporate store, which can make it difficult to retain managers. When Chili’s is looking for hourly employees, it offers several opportunities to them. They can apply and interview online, receive benefits and have the opportunity to grow with the company. Their hourly employee turnover rate is also lower than the industry average. Chili’s Weaknesses Even though the Chili’s brand is recognizable, it doesn’t appeal to the upper class. The casual dining concept, no matter how different, is still the same. They receive much of their food frozen, unlike Ruby Tuesday which receives all of their meat and produce fresh, making some items not the best of quality. During the busy times, servers are pressured to decrease their table turn time, the time from when a guest sits at the table until they leave and the table is ready for another guest, which can make it difficult to build a rapport with their guests, but at the same time they want their PPA (per person average) to be higher. Many of their restaurants are focused around the bar, which segregates some consumers that do not want to be in that environment. It also makes their seating area than some of their competitors. Chili’s Opportunities There are several things Chili’s can do to remain competitive in the casual dining industry. They can continue to expand internationally, beyond the 20 countries they are already in. Their competitors have yet to exceed that with Ruby Tuesday’s being in about twelve countries and Applebee’s is in almost twenty. They have a very well known brand which will allow them to continue expansion at a rapid rate with the backing of their parent company, Brinker Intl. They are launching a program to try international cuisines at some of their foreign locations. If consumers react positively this could be a great growth opportunity, if it is not taken to, it could be a threat to their international stores if they continue it. They can enlarge their restaurants or configure different models, based on the demographics of the area, to include more seating for guests and not just the bar area. They can continue to expand their brand recognition apparel and glassware. Chili’s Threats The largest threat to the Chili’s brand is the competition of casual dining restaurants, which are easy to duplicate. Applebee’s and Ruby Tuesday’s both had higher 1-year sales growths, with 10% and 17. %, respectively, compared to Chili’s at 6. 1%. Chili’s saturated some U. S. markets and has no where else to expand in those areas. They need to keep up with current trends and eating habits, because they change often, to stay current with the market. Summary Chili’s has managed to saturate the US and foreign markets better than its competitors. Their sales are higher and they retain their employees longer. They need to look at a few things like following eating trends and standing out from the competition a bit more, but they are a highly competitive company that keeps people coming back.

Aristotle’s Elements of Tragedy Essay -- Creek, Poetics, Tragedy

Aristotle is one of the most important western philosophers in history that has influenced our society in many aspects. Many of Aristotle’s teachings have affected our world for many years and still continue to have such a big impact. Some of the subjects Aristotle has influenced include: logic, physics, government and poetry. Aristotle’s study of poetry mainly focused on the elements to a good tragedy. Some of his elements have been used in Greek tragedies and modern movies. The Greek play, Medea, and the modern movie, No Country for Old Men, use elements from Aristotle philosophy, while using similar and different techniques but both achieving an effective tragedy. In Aristotle’s book, Poetics, he defines tragedy as, â€Å"an imitation of an action that is serious, complete, and possessing magnitude; in embellished language, each kind of which is used separately in the different parts; in the mode of action and not narrated; and effecting through pity and fear† (Aristotle 1149). Tragedy creates a cause and effect chain of actions that clearly gives the audience ideas of possible events. The six parts to Aristotle’s elements of tragedy are: Plot, character, language, thought, spectacle, and melody. According to Aristotle, the most important element is the plot. Aristotle writes in Poetics that, â€Å"It is not for the purpose of presenting their characters that the agents engage in action, but rather it is for the sake of their actions that they take on the characters they have† (Aristotle 1150). Plots should have a beginning, middle, and end that have a unity of actions throughout the play making it complete. In addi tion, the plot should be complex making it an effective tragedy. The second most important element is character. Characters... ...hough the two demonstrate the elements in different ways, they both achieve an effective tragedy. Now after learning about Aristotle’s philosophy on tragedy, one can examine any type of tragic poetry, play, movie and analysis if the elements are portrayed. Its interesting to see how much of Aristotle’s philosophy has effected poetry in the art of the Greek tragedy, Medea, and the modern movie, No Country for Old Men. Works Cited Aristotle. Poetics.

Thus, in this paper, we have designed a ladder diagram for running PLC with the objective to automatically control the hydraulic system. Our main requirement is to design a PLC which can be connected to hydraulic system to implement the parameters and operations like Temperature detection, Pressure detection, Lubrication, Automatic machine operation and Oil level detection.The mentioned parameters and operations can be sensed and operated through PLC without any manual checking and operation. This saves more power to industries by reducing the power consumption. INTRODUCTION In the last decades, the machines used in the industries were operated manually. So keeping its certain important parameters in a specific range was difficult. Also they can not be checked out frequently. This results in improper functioning of the machine. Also, the machines cannot work efficiently for a long time.For example, if the temperature of the oil goes beyond the desired value it will affect the machine function. Hence the machine accessories cannot withstand this high temperature. This leads to the damage in machine and the durability of the machine also gets reduced. Thus, the working machine requires frequent checking of certain parameters to maintain the value within the specified range for proper operation. The var ious parameters to be checked frequently are: 1. Temperature detection 2. Lubrication 3. Automatic machine operation 4. Oil level detection . Pressure Thus we are using a PLC to control all these parameters. We are designing a ladder diagram to control all the parameters automatically. In this paper, we are describing about the hydraulic drive system in which PLC is used to control its working. An introduction of PLC is provided and also the ladder diagram overview. We will be discussing about the advantages of PLC and also the power saving estimation in the industries by using PLC. The machine which we have taken under consideration for implementation is BOW CORRECTION MACHINE.Also, the chiller unit is described as it plays a major role for the power saving purpose. HYDRAULIC DRIVE SYSTEM : A  hydraulic drive system  is a drive or  transmission  system that uses pressurized  hydraulic fluid  to drive  hydraulic machinery. The term hydrostatic refers to the transfer of energy from flow and pressure, not from the  kinetic energy  of the flow. Principle of a hydraulic drive Pascal's law  is the basis of hydraulic drive systems. As the pressure in the system is the same, the force that the fluid gives to the surroundings is therefore equal to pressure ? rea. In such a way, a small piston feels a small force and a large piston feels a large force. For an understanding of how a hydraulic system works, we must know the basic principles, or laws, of hydraulics, that is, of confined liquids under pressure. This will be made easier, however, if we first examine the somewhat simpler laws governing the behavior of liquids when  unconfined, that is, in open containers. 1. Liquids in open containers. a. Density and specific gravity. The first characteristic of an unconfined liquid which interests us is its density.The density of a fluid is the  weight of a unit volume of it. The unit of volume normally used in this text is the cubic foot; the unit o f weight normally used is the pound. The standard of density, to which the densities of all other liquids are referred, is that of pure water at zero degrees centigrade (32 degrees Fahrenheit), and at sea-level atmospheric pressure. b. Force and pressure. A liquid has no shape of its own. It acquires the shape of its container up to the level to which it fills the container. However, we know that liquids have weight.This weight exerts a force upon all sides of the container, and this force can be measured. Therefore, for unconfined liquids, that is, liquids in open containers, the pressure in pounds per square inch exerted by the liquid on the bottom of the container is equal to the weight of the liquid on each square inch of the bottom of the container. It must be emphasized that the  weight  of the liquid is here thought of as a  forceexerted on the bottom of the container. Expressed as a formula, we have: Pressure = Force per unit areaIt is understood that the word pressure , when not otherwise qualified, means  pressure in pounds per square inch. This is called the total force and is obtained by the formula: Total Force = Pressure X Area The pressure exerted by a liquid on the bottom of a container is independent of the shape of the container, and depends only on the height and density of the liquid. 2. Liquids in enclosed systems. a. Liquids are practically incompressible. The following two basic principles will help to explain the behavior of liquids when enclosed: a) Liquids are practically incompressible. ) The applied pressure is transmitted equally in all directions at once. b. Increase of force with area. The ratio between the  force applied to the smaller piston  and the  force applied to the larger piston  is the same as the ratio between the  area of the smaller pistonand the  area of the larger piston. Expressed as a proportion, then, we have: Force on larger piston/Force on smaller piston = Area of larger piston/Area of small er piston This means that the mechanical advantage obtainable by such an arrangement is equal to the ratio between the areas of the two pistons.Since the area of the larger cylinder is 10 times as great as that of the smaller cylinder, pushing the smaller piston downward a distance of 1 inch will move the larger piston upward only 1/10 of an inch. The ratio between the displacement of liquid in the smaller cylinder and the displacement of liquid in the larger cylinder is once again equal to the ratio between their areas. so that the amount of work (force X distance) done by the larger piston is exactly the same as the amount done by the smaller piston. c. Multiple units.It is not necessary to confine our system to a single line from the source of hydraulic power. Hydraulic power may be transmitted in many directions to do multiple jobs. PUMP – In practice we usually need some device which will deliver, over a period of time, a definite volume of fluid at the required pressure , and which will continue to deliver it as long as we desire it to do so. Such a device is called a  pump. Basic principles of pumps. A hydraulic pump is a mechanical device which forcibly moves, or displaces, fluids.Various pumping principles are employed in the different types of hydraulic pumps, but one fundamental principle applies to all: a volume of fluid entering the intake opening, or port, is moved by mechanical action and forced out the discharge port. Hydraulic fluids. Almost any free-flowing liquid is suitable as a hydraulic fluid, as long as it will not chemically injure the hydraulic equipment. For example, an acid, although free-flowing, would obviously be unsuitable because it would corrode the metallic parts of the system. a. Basic units of a hydraulic system. 1.A reservoir, or supply tank, containing oil which is supplied to the system as needed and into which the oil from the return line flows. 2. A pump, which supplies the necessary working pressure. 3. A hydra ulic cylinder, or actuating cylinder, which uses the hydraulic energy developed in the pump to move the door. 4. A cut-out valve, by means of which the pressure in the actuating cylinder may be maintained or released as desired. 5. A check valve, placed in the return line to permit fluid to move in only one direction. 6. â€Å"Hydraulic lines,† such as piping or hose, to connect the units to each other.The supply tank must have a capacity large enough to keep the entire system filled with oil and furnish additional oil to make good the inevitable losses from leakage. The tank is vented to the atmosphere; thus atmospheric pressure (14. 7 pounds per square inch) forces the oil into the inlet, or suction, side of the pump. The tank is generally placed at a higher level than the other units in the system, so that gravity assists in feeding oil into other units. The pump is the hand-operated, reciprocating piston type. SOLENOID VALVE : A  solenoid valve  is an  electromechan ically  operated  valve.The valve is controlled by an  electric current  through asolenoid: in the case of a two-port valve the flow is switched on or off; in the case of a three-port valve, the outflow is switched between the two outlet ports. Multiple solenoid valves can be placed together on a  manifold. Solenoid valves are the most frequently used control elements in  fluidics. Their tasks are to shut off, release, dose, distribute or mix fluids. They are found in many application areas. Solenoids offer fast and safe switching, high reliability, long service life, good medium compatibility of the materials used, low control power and compact design.There are many valve design variations. Ordinary valve can have many ports and fluid paths. A 2-way valve, for example, has 2 ports; if the valve is  closed, then the two ports are connected and fluid may flow between the ports; if the valve is  open, then ports are isolated. If the valve is open when the solenoid is n ot energized, then the valve is termed  normally open  (N. O. ). Similarly, if the valve is closed when the solenoid is not energized, then the valve is termednormally closed. [1]  There are also 3-way and more complicated designs.A 3-way valve has 3 ports; it connects one port to either of the two other ports (typically a supply port and an exhaust port). Solenoid valve are also characterized by how they operate. A small solenoid can generate a limited force. If that force is sufficient to open and close the valve, then a  direct acting  solenoid valve is possible. An approximate relationship between the required solenoid force  Fs, the fluid pressure  P, and the orifice areaA  for a direct acting solenoid value is: Where  d  is the orifice diameter. A typical solenoid force might be 15  N (3.   lbf). An application might be a low pressure (e. g. , 10 pounds per square inch (69  kPa)) gas with a small orifice diameter (e. g. ,  3? 8  in (9. 5  mm) fo r an orifice area of 0. 11  sq  in (7. 1? 10? 5  m2) and approximate force of 1. 1  lbf (4. 9  N)). When high pressures and large orifices are encountered, then high forces are required. To generate those forces, an  internally piloted  solenoid valve design may be possible. [1]  In such a design, the line pressure is used to generate the high valve forces; a small solenoid controls how the line pressure is used.Internally piloted valves are used in dishwashers and irrigation systems where the fluid is water, the pressure might be 80 pounds per square inch (550  kPa) and the orifice diameter might be  3? 4  in (19  mm). In some solenoid valves the solenoid acts directly on the main valve. Others use a small, complete solenoid valve, known as a pilot, to actuate a larger valve. While the second type is actually a solenoid valve combined with a pneumatically actuated valve, they are sold and packaged as a single unit referred to as a solenoid valve.Piloted valv es require much less power to control, but they are noticeably slower. Piloted solenoids usually need full power at all times to open and stay open, where a direct acting solenoid may only need full power for a short period of time to open it, and only low power to hold it. A direct acting solenoid valve typically operates in 5 to 10 milliseconds. The operation time of a piloted valve depends on its size; typical values are 15 to 150 milliseconds. Solenoid valves are used in  fluid power  pneumatic and hydraulic systems, to control cylinders, fluid power motors or larger industrial valves.Automaticirrigation sprinkler  systems also use solenoid valves with an automatic  controller. Domestic  washing machines  and  dishwashers  use solenoid valves to control water entry into the machine. Solenoid valves are used in  dentist chairs  to control air and water flow. In the  paintball  industry, solenoid valves are usually referred to simply as â€Å"solenoids. â €  They are commonly used to control a larger valve used to control the propellant (usually compressed air or CO2). In addition to this, these valves are now been used in household water purifiers (RO systems).Besides controlling the flow of air and fluids, solenoids are used in pharmacology experiments, especially for patch-clamp, which can control the application of agonist or antagonist. Many variations are possible on the basic, one-way, one-solenoid valve described above: * one- or two-solenoid valves; * direct current  or  alternating current  powered; * different number of ways and positions; INTRODUCTION TO PLC : A  Programmable Logic Controller, or PLC, is more or less a small computer with a built-in operating system (OS). This OS is highly specialized to handle incoming events in real time, i. . at the time of their occurrence. The PLC has input lines where sensors are connected to notify upon events (e. g. temperature above/below a certain level, liquid level reached, etc. ), and output lines to signal any reaction to the incoming events (e. g. start an engine, open/close a valve, etc. ). The system is user programmable. It uses a language called â€Å"Relay Ladder† or RLL (Relay Ladder Logic). The name of this language implies that the control logic of the earlier days, which was built from relays, is being simulated.The PLC is primarily used to control machinery. A program is written for the PLC which turns on and off outputs based on input conditions and the internal program. In this aspect, a PLC is similar to a computer. However, a PLC is designed to be programmed once, and run repeatedly as needed. In fact, a crafty programmer could use a PLC to control not only simple devices such as a garage door opener, but their whole house, including switching lights on and off at certain times, monitoring a custom built security system, etc.Most commonly, a PLC is found inside of a machine in an industrial environment. A PLC can run an automatic machine for years with little human intervention. They are designed to withstand most harsh environments. When the first electronic machine controls were designed, they used relays to control the machine logic (i. e. press â€Å"Start† to start the machine and press â€Å"Stop† to stop the machine). A basic machine might need a wall covered in relays to control all of its functions. There are a few limitations to this type of control. * Relays fail. * The delay when the relay turns on/off. There is an entire wall of relays to design/wire/troubleshoot. A PLC overcomes these limitations, it is a machine controlled operation. PLCs are becoming more and more intelligent. In recent years PLCs have been integrated into electrical communications  networks  Ã¢â‚¬â€œ i. e. , all the PLCs in an industrial environment have been plugged into a network which is usually hierarchically organized. The PLCs are then supervised by a control center. There exist many propri etary types of networks. One type which is widely known is  SCADA  (Supervisory Control and Data Acquisition).The PLC is a purpose-built machine control computer designed to read digital and analog inputs from various sensors, execute a user defined logic program, and write the resulting digital and analog output values to various output elements like hydraulic and pneumatic actuators, indication lamps, solenoid coils, etc. Scan cycle Exact details vary between manufacturers, but most PLCs follow a ‘scan-cycle' format. Overhead Overhead includes testing I/O module integrity, verifying the user program logic hasn't changed, that the computer itself hasn't locked up (via a watchdog timer), and any necessary communications.Communications may include traffic over the PLC programmer port, remote I/O racks, and other external devices such as HMIs (Human Machine Interfaces). Input scan A ‘snapshot' of the digital and analog values present at the input cards is saved to an i nput memory table. Logic execution The user program is scanned element by element, then rung by rung until the end of the program, and resulting values written to an output memory table. Output scan Values from the resulting output memory table are written to the output modules. Once the output scan is complete the process repeats itself until the PLC is powered down.The time it takes to complete a scan cycle is, appropriately enough, the â€Å"scan cycle time†, and ranges from hundreds of milliseconds (on older PLCs, and/or PLCs with very complex programs) to only a few milliseconds on newer PLCs, and/or PLCs executing short, simple code. ADVANTAGES OF PLC: * PLC’s have flexibility (i. e. ) it is possible to use just one model of PLC to run any one of the 15 machines. * In a PLC program circuit the PLC program can be used from any keyboard sequence in a matter of minute and rewriting is required. PLC has a large number of contacts for each coil in its programming. * I ncreased technology makes it possible to compact move functions into smaller and less expensive packages. * A PLC programmed circuit can be pre-un ad evaluated in the officer or lab. The program can be typed in tested observed and modified if needed. * PLC circuit operation can be seen during operation directly on a CRT screen. * The operation speed for the PLC program is very fast. * PLC is more reliable. * A PLC programmer who works in digital or Boolean control system can easily perform PLC programming. PLC’s program can’t be made unless the PLC properly unlocked and programmed. LADDER LOGIC DIAGRAM : What is a Ladder Diagram? A Ladder Diagram is one of the simplest methods used to program a PLC. It is a graphical programming language evolved from electrical relay circuits. Each program statement is represented with a line, called the rung, that has all relevant inputs to the left and the output to the right. The output device of a rung is energized if electric powe r can conceptually flow from the left side of the rung to the right side.Input devices are assumed to block the flow of power if they are not activated. During the execution of a ladder diagram, the PLC reads the states of all inputs, then determines the states of all outputs starting from the rung at the top side, going down to the last rung, and finally updates the state of the output devices. * Naming Convention During the development of a PLC program, we must use specific names to identify the inputs, outputs, memory flags, timers and counters. PLC manufactures use a variety of approaches in naming the inputs, outputs and other resources.A typical naming convention is to identify inputs with the letter â€Å"I† and outputs with the letter â€Å"O†, followed be a 1-digit number that identifies the slot number and a 2-digit number that identifies the position of the input or output in the slot. For example: I1:00 refers to the first input of slot 1 O2:00 refers to th e first output of slot 2. Some manufactures number the inputs or outputs starting from 00, while others use the number 01 to identify the first input or output. It is also common to use numbers like 400 e. t. c. The state of an output can be also used as an input in a ladder diagram.In such a case the PLC uses the state of the specific output device that is stored in the output image memory. * Relay Logic Instructions (XIC and XIO) Examine if Closed (XIC) —–[ ]—— Use the XIC instruction in your ladder program to determine if a bit is On. When the instruction is executed, if the bit addressed is on (1), then the instruction is evaluated as true. When the instruction is executed, if the bit addressed is off (0), then the instruction is evaluated as false. Examine if Open (XIO) ——-[/]—— Use the XIO instruction in your ladder program to determine if a bit is Off.When the instruction is executed, if the bit addressed is off (0), the n the instruction is evaluated as true. When the instruction is executed, if the bit addressed is on (1), then the instruction is evaluated as false * Relay Logic Instructions: Input Transition Sensing Positive Transition Sense (PTS) The condition of the right link is ON for one ladder rung evaluation when a change from OFF to ON at the specified input is sensed. Negative Transition Sense (NTS) The condition of the right link is ON for one ladder rung evaluation when a change from ON to OFF at the specified input is sensed. * Output Instructions Output Energize (OTE) —-( )—– If the condition of the left link of the OTE is ON then the corresponding bit in the output data memory is set. The device wired to this output is also energized. Negative Output Energize (NOE) ——(/)—– If the condition of the left link of the OTE is OFF then the corresponding bit in the output data memory is set. The device wired output is also energized. Output L atch/Set (OTL) and Output Unlatch/Reset (OTU) If the condition of the left link of the OTL is momentary ON then the corresponding bit in the output data memory is set, and remains set even if the condition switches to the OFF state.The output will remain set until the condition of the left link of the OTU is momentary ON * Basic Logic Functions (OR, AND) Two Input OR Function The output is ON only if the two inputs are OFF. Two Input AND Function The output is ON if both of the two inputs are ON. * Basic Logic Functions (NAND,NOR) Two Input NAND Function The output is ON if any of the two inputs is OFF. Two Input NOR Function The output is ON if both of the two inputs are OFF. * Basic Logic Functions (EXOR, EXNOR) Two Input EXOR Function The output is ON if any of the two inputs is ON, but not both. Two Input EXNOR FunctionThe output is ON if both of the two inputs are either OFF or ON. * Set/Reset Latch Set/Reset Latch using a Hold-in contact Set/Reset Latch using Latch/Unlatch out puts Notes: O1:00’ means that the output is unchanged If both inputs are ON then normally the output is OFF, since the Unlatch rung appears last in the ladder diagram. * Timer Instructions Timer Instructions are output instructions used to time intervals for which their rung conditions are true (TON), or false (TOF). These are software timers. Their resolution and accuracy depends on a tick timer maintained by the microprocessor.Each timer instruction has two values (integers) associated with it: Accumulated Value (ACC): This is the current number of ticks (time-base intervals) that have been counted from the moment that the timer has been energized. Preset Value (PR): This is a predetermined value set by the programmer. When the accumulated value is equal to, or greater than the preset value, a status bit is set. This bit can be used to control an output device. Each timer is associated with two status bits: Timer Enable Bit (EN): This bit is set when the rung condition to t he left of the timer instruction are true.When this bit is set, the accumulated value is incremented on each time-base interval, until it reaches the preset value. Done Bit (DN): This bit is set when the accumulated value is equal to the preset value. It is reset when the rung condition becomes false. * Timer On-Delay (TON) Instruction The TON instruction begins count when its input rung conditions are true. The accumulated value is reset when the input rung conditions become false. Timer ladder diagram example. Typical timing diagram (Assume that Preset = 07). * Timer Off-Delay (TOF) InstructionThe TOF instruction begins count when its input rung makes a true-to-false transition, and continues counting for as long as the input rung remains false. The accumulated value is reset when the input rung conditions become false. Timer ladder diagram example. Typical timing diagram (Assume that Preset = 07). * Retentive Timer (RTO) Instruction The RTO instruction begins count when its input rung conditions are true. The accumulated value is retained when the input rung conditions become false, and continues counting after the input rung conditions become true. * Counter InstructionsCounter Instructions are output instructions used to count false-to-true rung transitions. These transitions are usually caused by events occurring at an input. These counters can be UP (incrementing) or DOWN (decrementing). Each counter instruction has two values (integers) associated with it: Accumulated Value (ACC): This is the current number of the counter. The initial value is zero. Preset Value (PR): This is a predetermined value set by the programmer. When the accumulated value is equal to, or greater than the preset value, a status bit is set. This bit can be used to control an output device.Each counter is associated with two status bits: Counter Enable Bit (EN): This bit is set when a false-to-true rung condition to the left of the counter instruction is detected. Done Bit (DN): T his bit is set when the accumulated value is equal to the preset value. It is reset when the rung condition becomes false. The maximum count value is 9999*. After a maximum count is reached, the counters reset and start counting from zero. * Count-up (CTU) Instruction The CTU instruction increments its accumulated value on each false-to-true transition at its input, starting from 0.

Counter ladder diagram example. Typical timing diagram (Assume that Preset = -10). * The Reset (RES) Instruction The RES instruction resets timing and counting instructions. When the RES instruction is enabled it resets the following. Counters:Accumulated value, Counter Done Bit , Counter Enabled Bit. Timers: Accumulated value, Timer Done Bit, Timer Timing Bit, Timer Enable Bit.R eset ladder diagram example.

In the pipes used in boilers, small pipes are attached using welding. This welding makes the pipe to bent. Thus its surface becomes uneven and makes it imperfec t to be used in boilers. In this case this machine is used. Using this machine the bents and bows can be straightened and makes the pipes perfect to be used in the boilers. CIRCUIT DIAGRAM : OPERATION.The hydraulic circuit is designed to achieve fast approach speed, slow pressing speed and fast return speeds by use of a single pump. The fast approach speed is achieved by ensuring that the cylinder ram moves down through its self weight or what is termed as gravity fall. To achieve gravity fall of the cylinder of the cylinder it is important to ensure that at all times the pressure in return line is minimum 5 kg/ cm2. On starting the motor the pump delivery is directed to the tank through unloading type relief valve no. 4. The same flow is directed to the Z1 lines of catridge valves 5 ; 7, which ensures that the valves are closed.On operation of solenoid S1 of main relief valve the pump flow is directed to the catridge valves, however due to differential areas the catridges are still closed and pump reaches system pressure and unloads to tank through relief valve 4. On operation of solenoid S2( valve 6) along with S1, Port A of solenoid valve no. 6 is connected to tank Y1 which facilitates opening of catridge valve 5 and hence the oil flows into the forward line of the cylinder resulting in downward movement. At the same time the oil in the return line of the cylinder is connected to tank at the set pressure through valve no. 11.Hence the cylinder moves down with slow pressing speed. On operation of solenoid S4 ( valve 8) along with S1 ; S2 the X port of catridge valve 10 is connected to tank through valve 8, 6 and port Y1 that ensures the opening of the catridge valve 10. Opening of the catridge valve ensures that the return line is connected directly to tank and hence the cylinder oves down with its self weight and fast approach speed is achieved. At the same time prefill valve 14 opens to fill the cylinder forward area with oil. To set the maximum fast appro ach speed valve 10 is provided with a stroke adjustment setting.On operation of solenoid S3(valve 6) along with S1, port B of solenoid valve no. 6 is connected to tank Y1 which facilitates opening of catridge valve 7 and hence oil flows into the return line of the cylinder. At the same time since A port of solenoid valve no. 6 is connected to pump port X4 is also connected to pump, ensures the opening of prefill valve no 14 and that the forward line of the cylinder is connected back to tank. This results in reverse movement of the cylinder. Pressure relief valve 9 is provided to ensure smooth deceleration of the cylinder from fast approach to pressing.The valve ensures that the pressure in X port of the cartridge valve does not exceed set pressure therby ensuring that the valve closes slowly reducing jerks. The hot oil from the machine is then sent to the chiller unit to reduce its temperature. CHILLER UNIT: In the chiller unit, the refrigerant is used to cool down the hot oil from the machine. REFRIGERATION: A liquid whose Saturation temperature at normal atmospheric pressure is below the temperature that is to be produced by refrigeration is chosen as the working liquid in the refrigerant.Such a liquid will evaporate at lower temperatures and will absorb hear as it does so. This heat is extracted from the surroundings. The vapour formed in this way is compressed in a compressor. After compression the refrigerant may be in the vapour state or, in the liquid state if its temperature after compression is not greater than the saturation temperature at that increase pressure. The low temperature vapour is condensed in a condenser, in doing so it lowers its temperature below the surroundings . Now the condensed liquid is expanded to a lower pressure and the cycle of refrigeration is repeated.REFRIGERATION CYCLE: * Compressors are used in vapour compression cycles. It is the heart of the system and it sucks low-pressure refrigerant vapour from the evaporator and co mpresses it to a pressure corresponding to the saturation temperature that will be higher than continuously re-circulate the refrigerant through the system. * Air-cooled condensers are heat exchangers,which reject heat from the condensing refrigerant to the atmosphere. * The function of condenser in a refrigerated system is to de-superheat and condense the compressed discharge refrigerant vapour.High-speed fans are mostly used to speed up the process. * At the exit of the condenser the refrigerant loses temperature but still is in high-pressure state. The temperature falls down a little high to the ambient. * Dryers are mainly used to capture the moisture content if any mixed with the refrigerant. When the refrigerant passes through its thin filter mesh the moisture gets trapped on the silica gel and clean refrigerant flows through. * Throttle valve(also called as Expansion valve)is also a very important component of the vapour compression refrigeration system.The function of an exp ansion device is to expand the liquid refrigerant from the condensing pressure to the evaporating pressure. Also it throttles the required flow into the evaporator depending on the load conditions. Commonly used expansion devices are capillary tubes, thermostatic expansion valves and constant pressure expansion valves. * Any liquid when evaporate creates a cooling effect. Same applies here, when the refrigerant exists expansion valve it is partly in vapour state at low temperature and pressure. It flows through the evaporator and exchanges heat with the surroundings. After existing the evaporator it has gained heat from the surrounding media, thus lowering the temperature in the freezing compartment. This superhead vapour passes further and is drawn by the compressor, which compresses it,and delivers to condenser, thus, completing the refrigeration cycle.

Hence, the chiller unit has to function continuously irrespective of hydraulic oil’s temperature. * Possibilities of machine can run due to friction since there is no Indication of oil in tank. * The chiller unit is running continuously hence there is a possibilities of lot of Energy consumption losses. * There is no automatic control for the whole machine. * There is no automatic function for declamping and lubrication. There is no oil level sensor in the hydraulic tank to sense the oil level in the tank. * Relays are used which is not automatic and inefficient. HORIZONTAL BORING MACHINE HY DRAULIC TANK CHILLER UNIT PUMP SOLENOID VALVE PROPOSED SYSTEM: * In this method there is a temperature sensor which is used to sense the temperature of the oil in the hydraulic tank. * The chiller unit will be turned on only when the oil temperature gets increased with the specified value of oil temperature * Friction of the machine can be reduced by implementing the lubrication function. Oil level in the hydraulic tank can be detected by using an oil level sensor . * Two types of oil level sensor is used. I. Low level sensor II. Very low level sensor So that we can avoid the machine running in dangerous condition. * All the operation in one axis (x or y or z) can be operated by a single push button switch. * Declamping and lubrication function takes place automatically. ENERGY SAVING CALCULATION: * WITH CHILLER UNIT WORKING CONTINUOUSLY: For continuous running of chiller unit the motor consumes 18KW. Per day: morning -4hrs night -8hrs so chiller unit runs totally 12hrs a day. 8KW*1 2hrs=216 KWhr The chiller unit consumes 216KWhr per day. For electricity: 1unit= Rs. 5 Therefore 216*5= 1080 So for 216 unit it costs Rs. 1080 per day. 1080*30=Rs. 32,400 For 1month it costs Rs. 32,400 32400*303= Rs. 98,17,200 For 1year it costs Rs. 98,17,200. * WITH PLC: For automatic on/off of chiller unit the motor consumes 10KW. Per day: morning -4hrs night -8hrs so chiller unit runs totally 12hrs a day. 10KW*12hrs=120KWhr The chiller unit consumes 120KWhr per day. For electricity: 1unit= Rs. 5 Therefore 120*5= 600 So for 120unit it costs Rs. 600 per day. 600*30=Rs. 8,000 For 1month it costs Rs. 18,000 18000*303= Rs. 54,54,000 For 1year it costs Rs. 54,54,000.
