Mechanical vibration - Coursework Example The European Standards set out in ISO 2631-1 provide a criterion through which vibrations can be evaluated, analysed, and monitored. The purpose of this standard is to protect employees from unnecessary and harmful modes of vibration in the work place. The BS EN 14253:2003+A1:2007 is an essential document that aids in calculating vibration doses an employee gets when using vibration equipment. Through the calculations, the employee is assured of his health as well as good practices for vibratory equipment (Finucane, 2006). The document contains methods of measuring and establishing the daily exposure of vibration. This can then be compared to the required daily dosage units for the purpose of employee safety and health. EN 30326-1-this norm of reference reflects mechanical vibration, with a detail outline of laboratory methods used to evaluate vehicle seat vibration. Its Part I outlines the ISO 103236-1:1992 for the basic requirements. The evaluation of exposure to vibration by employees is based on two principles; the frequency-weighted acceleration and the total duration of exposure to vibration per day. Frequency-weighted acceleration is expressed in m/s ², reported as Root Mean Square (RMS) value. On the other hand, the total exposure to vibration per day is denoted as Ti with the denotation i reflecting the particular operation. Using the two principle guidelines for evaluation of quantities for vibration exposure, exposure profile defines the dosage of vibration an employee is exposed to, using the value A(8). This requires accurate measurement of the sources of vibration on a frequent basis. The exposure profile also states measurements made in the context of daily vibration exposure. Since the operations are identified, important factors must be considered. These are; One of the sources of whole-body vibration is a travelling car. A comparative assessment was done on whole-body vibration exposure. The car

Organic farming has risen to a huge business because of its improved benefits of flavor and health. Organic farming has potential benefits for the environment of agricultural chemicals.  Nutritional quality and other factors are not the only reasons to buy organic foods. The rate of consumptio n of organic food has reduced the degree of exposure of antibiotic resistant and pesticide. Organic food is safe although it is hard estimating the cost of organic food. No level of pesticide is the best level in any human body in a family.   Organic foods are expensive than traditional foods. Organic products have different textures and flavors that are a little tasty. Organic products are expensive and only found in supermarkets and local markets. Another benefit for organic farming is because it slows environment and climate change.

Describe the events of the Bay of Pigs and the Cuban Missile Crisis Essay

Describe the events of the Bay of Pigs and the Cuban Missile Crisis. Do you think there was anything the U.S. could have done to handle these two events better - Essay Example The Bay of Pigs was an unsuccesful military invasion of Cuba by the paramilitary group sponsored by the CIA in April 1961. Two years before the invasion, Fidel Castro drove his guerrilla army into Havana and overthrew the president Fulgencio Batista (an American-backed President), paving the way for the communist rule in Cuba. For two years, the U.S. state department and the CIA attempted to overthrow the communist government, thus in 1961, the CIA launched a full-scale invasion of Cuba. However, the invaders were outnumbered by the Cuban forces and were defeated within less than 24 hours of fighting. The aftermath of the invasion at the Bay of pig led to a stronger tie between the Soviet Union and Cuba with the United States perceiving Cuba as a threat (Dunne, 448–458). The Cuban missile crisis was another scenario where the cold war exploded into actual combat war. The Cuban missile crisis was a thirteen-day confrontation between the Unites States and the Soviet Union over the latter’s ballistic missiles deployed in Cuba. The Cuban missiles were a response to the invasion of the Bay of Pigs. Additionally, the presence of American missiles in Italy and Turkey that was seen by the Soviet as a threat to their security prompting retaliation from USSR. The Russian missiles in Cuba were thus stationed as a means of protecting Cuba from future harassment by America. The Cuban missile crisis was resolved following a period of negotiation between President Kennedy and Khrushchev, with Soviet Union agreeing to remove the missiles from Cuba with a promise U.S will not invade Cuba without direct provocation (Schwarz, 73-81). Concerning the Bay of Pigs, the United States had little options other than to prepare a secret invasion team into Cuba in an attempt to overthrow the communist government. However, to make the invasion a success, the US government ought to have done a thorough assessment of the opponent before commencement of

Stock market efficiency Dissertation Example | Topics and Well Written Essays - 3250 words

Stock market efficiency - Dissertation Example profits over and above the profits made by the other players in the market by using this information. The hypothesis deals with two of the fundamental questions in finance. The first of them is why there is price change in the market for securities while the second considers how the change actually occurs. Investors involve themselves in identifying the securities that are expected to witness an increase in their value in the future. Moreover, they always try to identify those securities which will witness the maximum increase in their value. They are of the opinion that they have the capability to select only those securities that are expected to perform unexpectedly well in the market and drive the others out. In the process they use different forecasting techniques as well as some valuation methods. The combination of the techniques helps them in their decisions regarding investments. However the hypothesis states that the techniques are not effective and no one has the capability to predict the outperformance of the market. If the investors enjoy any advantage it is supposed not to exceed the incurred cost of transaction and research. Efficient market Hypothesis The theory suggests that it is extremely difficult to profit by predicting the movements in the prices. If in a market, the prices can adjust quickly without being biased to new information, such a market is called efficient markets. The availability of new information can lead to change in prices. The available information is reflected in the current prices of the securities taking a period under consideration. Adjustment in the price level takes place before an investor has sufficient time to trade and accrues profit from new information. Competition among the investors to accrue profit is one of the foremost reasons for the existence of efficient markets. Many are also involved in identifying the stocks that are mispriced. When more and more investment advisors or the market analysts spend time i n taking the advantage from the stocks that are either lowly priced or highly priced, the probability of detecting the securities that are mispriced becomes smaller. In a situation characterized by equilibrium, only a small number of analysts will be able to gain from the mis-priced securities because of the chance factor. All investments performing in the market are priced fairly. But it does not imply that they will perform in similar fashion because of the effect of rise or fall in the price level. The capital market theory states that the return expected from a security is a function of the risk. As the nature of the new information is unpredictable, the changes in the prices are expected to be random and the prices of the stocks follow the random walk theory. There are three versions of the hypothesis namely the weak form, the semi-strong form and the strong form of hypothesis. The weak form of efficiency states that the information about the history of prices only are incorpor ated in the current prices and that is why nobody can detect the securities that are mis-priced and gain from the gain by analyzing the prices of the past. The semi strong form of the hypothesis states that the current price reflects all the information that is available publicly. The last form of hypothesis that is the strong form asserts that all types of information namely public and private are reflected in the current price. The aim of all investors is to accrue maximum gains. The newly generated techniques to predict the movements in price have not been as successful as expected. If the risks and the costs of transaction are taken into account

Writing the History of the Australian Frontier Essay

Writing the History of the Australian Frontier - Essay Example However, Reynolds denied the claim by Windschuttle and stood by his original estimate. Thus, there started a conflict between the two distinguished figures over the number of Aboriginals killed in the frontier. "This skirmish was the first in what has since become known as the Aboriginal history wars. Windschuttle fired more shots in articles in the last four issues of Quadrant in 2000. Reynolds returned fire in a major article in the March 2001 issue of The Australian Review of Books. And there have been carefully staged verbal skirmishes in venues like Gould's Book Arcade in Sydney, on ABCTV Lateline and at the National Press Club in Canberra." (Ryan 2001, P. 31). Therefore, there has been a significant conflict of ideas and arguments by Henry Reynolds and Keith Windschuttle on the topic of writing the history of the Australian frontier and it is essential to comprehend the main areas of disagreement and agreement between the two. This paper undertakes an exploratory analysis of th e major arguments by Reynolds and Windschuttle in order to identify the major areas of disagreement and agreement between them, the evidence provided by each of them to support his position, and the utility of Ryan’s article to comprehend the realities of this controversy.... h Windschuttle has been their positions on the number of causalities in the Australian frontier and the two proposed significant substantive evidences to argue their positions. According to Reynolds, "It seems reasonable to suggest that Aborigines killed somewhere between 2,000 and 2,500 Europeans in the course of the invasion and settlement of the continent. There were many hundreds of others who were injured and carried both physical and psychological scars for the rest of their lives. Calculating the Aboriginal death toll is much more difficult For the continent as a whole it is reasonable to suppose that at least were killed as a direct result of conflict with the settlers." (Reynolds 1981, P. 99). Therefore, he mainly argues that the casualties can be calculated around 2,000-2,500 Europeans, and it is much more difficult to calculate the Aboriginal death toll. He also ascertains that Tasmania documented the conflict better than anywhere else in the country and Ryan's estimate of 800 is possibly more precise than the other estimations. The secondary effects of the invasion include disease, deprivation, and disruption which were responsible for the premature deaths of many more people and it is not possible to arrive at a realistic figure on the question. Windschuttle confronted the views by Reynolds on the number of deaths in the Australian frontier and his article "The Myths of Frontier Massacres in Australian History," claimed that many massacres of Aborigines in the Australian frontier were fabricated pointing out that the number of casualties in the frontier was far fewer than estimations of Henry Reynolds. He also disagrees with Reynolds' argument that the number of the Aborigines who died defending their territory outnumbers, in both relative and even

Hyundai Motor Company Business Challenges and Relationships Case Study

Hyundai Motor Company Business Challenges and Relationships - Case Study Example In a bid to penetrate the markets of the developed countries, the company’s packaging strategy faced great challenges. First, the company’s most expensive car model such as the Santa Fe and Sonata were undervalued when compared against their competitors in those markets. A research in these markets reviled that despite the cars from Hyundai ranking high in terms of quality scores when compared to their competitors, they still had lower resale values. A good example is the Hyundai’s Elantra which had higher quality rankings than the Dodge Neon, Nissan Sentra, and Chrysler but when it came to the resale values all these car models ranked well than it. Similarly, this was phenomena was also exhibited in the Hyundai Santa Fe. Its quality rankings ranked higher than that of competing models such as the Toyota RAV 4, Toyota Highlander, the Jeep Liberty, the Ford Escape and the Mazda Tribute. After one-year of sale, the retail value of the Hyundai Santa Fe was much lowe r than all these car models from competitors. To make matters worse the resale value gap between the Hyundai Santa Fe car and its competitors such as the car models from Toyota was larger than the quality gap between the car models. The resale value of a car is usually considered as the market’s perception of the quality, worth and value of that specific model. These low ranking of the models from Hyundai models in the markets of developed nations pose a great challenge to the survival of the company in those markets.

A View From The Bridge Essay Example for Free

A View From The Bridge Essay A View from the Bridge was written by Arthur Miller in 1955. The play is a modern tragedy with some elements of an Aristotelian tragedy. The play is set in the 1950s in the gullet of New York which is Red Hook.  In this essay I am going to explore if the protagonist, Eddie Carbone, is guilty for his downfall; which then leads to his death. A tragic hero has a fatal flaw which leads to his downfall, in Eddies case, he is attracted to his niece. This causes him to be overprotective and not let her meet anyone else, as he wants her for himself. The tragic heros downfall is brought about by ignoring advice; In Eddies case, he doesnt listen to Alfieri, the lawyer and chorus of the play, when he tells him to let Catherine go. My first impression of Eddie is a tall, big and quite overweight man, with little hair and a slowly dying face. He is an outgoing and hardworking man who provides for his family. I got some of these impressions because the chorus, Alfieri, describes him as, He is forty a husky slightly overweight longshoreman. The first person he talks to in the play is his niece, Catherine. At first he is caring when he comments on her new dress. But then he becomes a bit protective about her wearing it as he thinks it is too short and that men outside would stare. He is also reluctant to let her to go to work at first but when he sees she is sad he lets her do it, which shows us that he is more willing to make his niece happy than his wife. He talks to his wife, Beatrice like he would to any other wife but he does not go over to her to give her a hug or a kiss, just simply tells her something. But when he does, he sometimes holds her hands affectionately. This tells us that he expresses his feelin gs more easily in gestures than in words. Before Marco and Rodolpho arrive, Eddie is not too fond of them staying at his house, he complains that he may end up sleeping on the floor because of them. But then he talks about it being an honour for letting them stay over. When the cousins actually arrive, his attitude towards them changes dramatically. Earlier on he was saying Listen, as long as they know where there gonna sleep, and when they arrive he greets them;  Youre welcome, Marco, we got plenty of room here. Katie, give them supper, heh? Later on he only comes to address Marco only as he realises that Catherine is attracted to Rodolpho. He is coming more and more to address Marco only. He notices this as she keeps talking about Rodolphos facial appearance. The fall of Eddie Carbone begins when the cousins moved in. Rodolpho and Catherine are instantly attracted to each other, which angers Eddie very much as he is also attracted to her. Beatrice worries that Eddie dislikes Rodolpho because he likes Catherine, he responds, He sings on the ships, didja know that? This gives us a hint that he is trying to find things wrong with Rodolfo.  After this he visits Alfieri, the lawyer. He goes to ask him if he would be able to stop Rodolfo and Catherine marrying each other, but Alfieris advice to him is the child has to grow up and go away, and the man has to learn to forget. Because after all, Eddie what other way can it end? One other thing that Alfieri says hints at the truth, She wants to get married, Eddie. She cant marry you, can she? Eddie replies Whatre you talking about, marry me! I dont know what the hell youre talking about! He obviously knows what hes talking about, and Beatrice knows as well. The violent reaction from Eddie shows us that he fells ashamed that he loves his niece and fears that he will lose his dignity and respect.  Eddie doesnt listen to his advice but leaves the office in a dilemma. Knowing he cant do anything about Rodolfo, his attitude towards him changes dramatically. He stops talking to him in a civil manner and only speaks to mock him, such as when Rodolfo says, Lemons are green, and Eddie replies, I know lemons are green, for Christs sake. He says this almost to point out that Rodolfo is stupid. Every time he criticises Rodolfo he seems to look for support in his older brother, Marco. When he tries to teach Rodolfo how to fight, we see Marco being protective of his brother. When Eddie tries to land a punch on Rodolfo, the stage directions say it mildly staggers Rodolfo, Marco rises. After they have finished, Marco has his own test of masculinity. Marco says Can you lift this chair, a seemingly easy task. But Eddie cannot complete it and Marco carries on with showing him as the stage directions say, Rodolfo and Catherine have stopped dancing as Marco raises the chair over his head. Marco is face to face with Eddie, a strained tension gripping his eyes and jaw, his neck stiff, the chair raised like a weapon over his head and he transforms what might appear like a glare of warning into a smile of triumph. This shows us that Marco is no longer in support of Eddie and it is also a sign that he will defend and protect his brother if he is harmed. This leaves the audience tense at the end of Act One, which will make us focus more on the play. We become anxious about what happens from here on. We also know that a tragedy or something that will lead up to it, is going to occur in the beginning.
