Ralph and Jackââ¬â¢s Conflict between Good and Evil in Lord of the Flies Essay
?Ralph and Jackââ¬â¢s Conflict between Good and Evil in Lord of the Flies Over the ages, human behavior has shown that purity of thought leads to a similar action and ultimately to an outcome that is consistent with the original thought. Conversely, the history of man is tainted with his inherent lust for power and greed causing great conflict. In Lord of the Flies by William Golding, the author contrasts the moral thoughts and deeds of his flawed hero Ralph to the self gratifying motives and actions of his adversary Jack. The ebb and flow of good versus evil on the island is driven by the waves of positive and negative thoughts in the minds of the two main characters. Ralph and Jackââ¬â¢s continuous struggle of good versus evil is not only between the two of them, but is within their own minds as well. Jack shows his inclination towards selfishness and violence while Ralph keeps a caring and positive mind towards the groupââ¬â¢s survival. The boys have a meeting on the top of the mountain to discuss what to do next concerning their survival, which gives jack the opportunity to bring up hunting: ââ¬Å"ââ¬â¢It broke away-ââ¬Ë ââ¬ËBefore I could kill it- but- next time! ââ¬â¢ Jack slammed his knife into a trunk and looked round challenginglyâ⬠(31). Already Jack begins to reveal his aggressive and violent nature. Jack has the opinion that being dominant and seen as powerful is more important to his own survival, while Ralph thinks about the survival of the group as a whole. Jackââ¬â¢s hunting is more about a selfish need than about providing for others. During the first hunt, Jack goes to satisfy his craving for meat and power: ââ¬Å"He swung his right arm and hurled the spear with all his strength. From the pig-run came the quick, hard patter of hoofs, a castanet sound, seductive, maddening- the promise of meatâ⬠(49). Jackââ¬â¢s hunt for meat has become an obsessive search for power and a way to demonstrate his strength to the boys. He believes that catching and killing a pig and bringing it back for the others is the ultimate way to show that he is dominant and better than them. Jack is now consciously embodying his evil thoughts into his physical appearance. After realizing his hunting methods are not adequate, Jack paints his face into a mask in order to hunt more successfully: ââ¬Å"Jack planned his new face. He made one cheek and one eye-socket white, then rubbed red over the other half of his face and slashed a black bar of charcoal across from right ear to left jawâ⬠(66). He is consciously using the colours black and red to demonstrate the darkness and thirst for blood inside of him. Jack also shows his evil and anger in the way he aggressively slashes the charcoal onto his face. Ralphââ¬â¢s deeper level of thinking leads him to take positive action towards improving conditions on the island. Ralph walks along the beach and come to realization just how badly things have deteriorated on the island: ââ¬Å"With a convulsion of the mind, Ralph discovered dirt and decay; understood how much he disliked perpetually flicking the tangled hair out of his eyes, and at last, when the sun was gone, rolling noisily to rest among dry leavesâ⬠(82). Ralphââ¬â¢s thoughts, while not entirely good, have helped him to realize how bad the actually situation is on the island and what he needs to do to stop the situation from getting worse. Ralphââ¬â¢s world of order is pitted against Jackââ¬â¢s world of chaos. At the meeting, Ralph tries to reestablish the rules and Jack is openly challenging his authority: ââ¬Å"Ralph summoned his wits. ââ¬ËBecause the rules are the only thing weââ¬â¢ve got! ââ¬â¢ But Jack was shouting against him. ââ¬ËBullocks to the rules! Weââ¬â¢re strong- we hunt! If thereââ¬â¢s a beast, weââ¬â¢ll hunt it down! Weââ¬â¢ll close in and beat and beat and beat- ! ââ¬â¢Ã¢â¬ (99) Ralph expresses his good thoughts in a way to keep justice and order on the island, while Jack tries to destroy any trace of this with thoughts of rebellion and power over Ralphââ¬â¢s law. When Ralph realized that he cannot win, he gives into the bad thoughts that consume the island. Ralph is the last one left who still has a sense of order and is being hunted by the others for not agreeing with their ways: ââ¬Å"But then the fatal unreasoning knowledge came to him again. The breaking of the conch and the deaths of Piggy and Simon lay over the island like a vapour. These painted savages would go further and furtherâ⬠(204). He experiences bad thoughts regarding his survival and develops a sense of hopelessness and futility. Ralph, slowly losing his own sanity and at the loss of Piggy and Simon there to induce good thoughts, is left to hide and attack the others for his own survival. Ralph is entirely overwhelmed by the thoughts of good and evil. He flees from the savages onto the beach where he finds, standing before him, a naval officer with a ship at his back. ââ¬Å"â⬠¦ Ralph wept for the end of innocence, the darkness of manââ¬â¢s heart, and the fall though the air of the true, wise friend called Piggyâ⬠(225). All of Ralphââ¬â¢s thoughts crash down on him at this moment and he is overwhelmed by the truth of manââ¬â¢s inner evil and by the death of his loyal and good friend Piggy. The conflict between the two characters, Ralph and Jack, is underlined by the good and evil thought patters that directly lead to the actions they each take. While good thoughts bear good fruit and bad thoughts bear bad fruit, the potential for good and evil lies within all of mankind. Works Cited Golding, William. Lord of the Flies.

Incredible India Essay
Tourism is a major industry in India and the Ministry of Tourism launched a campaign to promote Incredible India as a tourist destination in 2002. [2] The phrase ââ¬Å"Incredible Indiaâ⬠was adopted as a slogan by the ministry. Before 2002, the Indian government regularly formulated policies and prepared pamphlets and brochures for the promotion of tourism, however, it did not support tourism in a concerted fashion. However, in 2002, the tourism ministry made a conscious effort to bring in more professionalism in its attempts to promote tourism. It formulated an integrated communication strategy with the aim of promoting India as a destination of choice for the discerning traveler. The tourism ministry engaged the services of advertising and marketing firm Ogilvy & Mather (India) (O&M) to create a new campaign to increase tourist inflows into the country. [3] Travel industry analysts and tour operators were appreciative of the high standards of the ââ¬ËIncredible Indiaââ¬â¢ campaign. ââ¬Å"The promo campaign is making a powerful visual impact and creating a perception of India being a magical place to visit,â⬠said Anne Morgaon Scully, President, McCabeBremer Travel, Virginia, USA. Average travelers too appeared to find the campaign interesting and informative, going by favourable comments on blogs on travel websites Although the ââ¬ËIncredible Indiaââ¬â¢ campaign was generally well received, industry observers differed in their opinions on the positioning of India in the campaign. G. S. Murari, Director, Fidelis Advertising and Marketing Pvt. Ltd. stated he was uncomfortable with the tagline ââ¬ËIncredible Indiaââ¬â¢ and was of the opinion that since India was not a uni-dimensional country like Singapore or the Maldives, using a word like ââ¬Ëincredibleââ¬â¢ to describe India as a whole was not appropriate. In 2011, Arjun Sharma, Managing Director, Le Passage to India, stated that the campaign has lived its life and it had to be reinvented. [8] The Ministry of Tourism has again engaged Ogilvy & Mather for a period of three year, beginning 2012, to redefine the brand and provide a strategic vision for the campaign. From ancient times, India has been looked upon as a place full of Mystique. In olden days time travelers like Huen Tsang came a long way with a great difficulty just to have felt of the place. But now in modern times, with supersonic jets, the world has become a smaller and has been named as a ââ¬Å"global villageâ⬠. With the destinations becoming so much closer the tourist are pouring into India from all over the world leading to a fast development of tourism industry and yet it has not grown to its fullest potential. History has lost count of hordes of humanity which have travelled and through this land of vibes and wisdom; explorers, travelers, traders and invaders have been drawn to her shores. Fa Hien and Hieun Tsang came from China in search of Bhuddhaââ¬â¢s calm serenity; from Alexander to Tamburlaine and Nadir Shah, Mahmud Ghaznavi, Muhammad Shah Ghauri to Babar, and Vasco-De-Gama to East India Company. All came here to fill their coffers with the wealth of this land; Jews, Parsees, Muhammedans, Christians, Arabs, Persians, Turks, Orientals and Europeanshave been all made welcome here. India has some incredibly beautiful spiritual destinations located all over the country. From the majestic peaks of Himalayas to the ghats of holy Ganga to numerous other holy sites, one can go for an unforgettable spiritual journey through this majestic country.

English Poetry
Emersonââ¬Å"The Echoing Greenâ⬠and ââ¬Å"The Eolian Harpâ⬠ââ¬Å"The Echoing Greenâ⬠is a poem written by William Blake. It was taken from Blakeââ¬â¢s Songs of Innocence, and is also a pictorial poem of Blakeââ¬â¢s. In this poem, the poet describes a happy country side view where the arrival of spring is welcomed by sunny skies, and ringing bells. It takes place on an ideal day in the British Isles. Blake uses the theme of innocence and peace throughout the poem. The theme plays out here when Blake states that the skies are happy, the children are playing, and the ââ¬â¢old folkââ¬â¢ who reminisce about their own childhood.This poem is a symbolic and draws a contrast between youth and old age. The spring symbolizes the youth and the children. Morning is the beginning of life and dark evening is the end. The poet symbolizes the innocence of children with birds. The birds are happy and they sing; mocking the children. ââ¬â¢Nest of birdsââ¬â¢ symboli zes peace. The poem could be attributed to the life of a person-birth, life, death. Birth being the morning, life being the kids playing, the routines throughout the day, and men reminiscing, and lastly death being the end of the day when all goes dark, and quiet smothers the earth. The Eolian Harpâ⬠, is a poem written by Samuel Taylor Coleridge. Inspired by the peaceful music being played by wind this poem was written for his wife, Sara, while visiting a house of his in Clevedon, Somersetshire. The theme in this poem is also peace, as well as innoncence. Peace comes to him while he ponders on the beauty of nature, and the wonder of God giving him everything around him including Sara. Coleridge personifies nature by comparing it to abstract nouns. For example, the white flower represents innocence.This abstract noun does exactly this: it gives life and character to nature. Coleridge uses unperceived nature to appeal to the human senses. Each are introduce in turn starting with sight through the watching of the clouds and the evening star. The introduction of God towards the end is another vision. ; a vision to the soul. It is now that the audience visualizes the peace that Coleridge feels. The allusion to sight and vision in these poems are significant because of the dept of imagination needed for physical and emotional imagery. Itââ¬â¢s full of emotional feelings, as well as physical sight.The audience is needed to picture, and feel what the poet did to understand the poem. For example, both Coleridge and Blake set the poem outside, in nature to show the peace and innocence. These two poems also have central connectedness. They both have vision and sight. Not only emotionally and mentally, but physical as well. There are many times where both poets use deep feelings and thoughts. Hiding meaning behind words, and using polsemes. Blake hides meanings behind his entire poem. Such as: morning being the beginning of life, and evening being the end. English Poetry In ââ¬ËBayonet chargeââ¬â¢ and ââ¬ËBelfast confettiââ¬â¢ the consequences of war are presented as inhumane, devastating and confusing by the poets. In both poems a range of semantic fields are used to display the confusion of the soldier in ââ¬ËBayonet chargeââ¬â¢ and the civilian in ââ¬ËBelfast confettiââ¬â¢. For example in ââ¬ËBelfast confettiââ¬â¢: ââ¬Å"Nuts, bolts, nails, car-keys. A fount of broken type. And the explosion. Itself ââ¬â an asterisk on the map. This hyphenated line, a burst of rapid fireâ⬠¦Ã¢â¬ Several semantic fields are used at once.For instance ââ¬Å"nuts, bolts, nails and car keysâ⬠belong to a semantic field of household objects, whilst ââ¬Å"asteriskâ⬠and ââ¬Å"hyphenated lineâ⬠would fit in to a semantic field of punctuation and ââ¬Å"explosionâ⬠and ââ¬Å"rapid fireâ⬠are part of wars semantic field. This use of variation in semantic fields creates a sense of confusion as the words do not fit in with the scene Carson is trying to paint, much like the civilian does not fit in with the war that is raging on around him. Similarly Hughes also uses the semantic field of nature as metaphors to create confusion: Stumbling across a field of clods towards a green hedgeâ⬠ââ¬Å"Clodsâ⬠are something used to describe mud or soil in a field. Here Hughes are using them as a metaphor for the people who had fallen during the charge. This metaphor shows how disorientated the soldier is, ââ¬Å"stumblingâ⬠around the field oblivious to what he was walking through. However the poet makes the soldiers ignorance sound as if it was forced, that in order to make it through the battle he had to ignore what was happening to his comrades.The metaphor ââ¬Å"field of clodsâ⬠also shows the inhumanity applied to warfare, making the soldiers appear as nothing more than pieces of earth not human beings who had lives and families. It also shows how devastating the battle s were, as an entire field has been covered with the remains of those fighting. ââ¬Å"Green hedgeâ⬠, another metaphor used in the quotation I have chosen, used to describe the end of the soldiers time on the battlefield. I felt that this was particularly powerful as the colour green and nature, in general, are used to represent life and hope, something which would seem out f place in a battlefield meaning that the metaphor also serves as an oxymoron. Both poems consist of many enjambments. Structuring the poem in such a way causes the poems to gain a stop, start rhythm. I felt that this made them sound like the train of thought coming from the subject of each poem. Often cutting off and continuing or switching points completely much like a person in a state of confusion unable to focus solely on one thing before finding more questions to ask to attempt to ease their confused state.By setting the poems out this way both Carson and Hughes allow the reader to be enveloped in the same state of confusion creating empathy between the reader and the subject. Hughes uses mechanical imagery in order to show the inhumane consequences of war: ââ¬Å"Sweating like molten iron from the centre of his chestâ⬠The use of the simile ââ¬Å"Molten ironâ⬠makes the soldier sound mechanical and inhumane as it appears to be coming from within the ââ¬Å"centre of his chestâ⬠.This suggests that the poet believes that war and conflict devastates a persons humanity, becoming nothing more than a weapon. This also adds to the effect of the verb ââ¬Å"Sweatingâ⬠showing us that despite how inhumane the soldier may be, he is still scared enough to be ââ¬Å"Sweatingâ⬠conveying his fear to the reader. Meanwhile Carson explores the devastating effect war has on the land it takes place on: ââ¬Å"I know this labyrinth so wellâ⬠The contrast within the quotation displays how much the area has been ruined.The phrase ââ¬Å"So wellâ⬠emphasises the de gree to which the subject knows the area he is talking about, the personal address term ââ¬Å"I knowâ⬠also creates a sense of desperation and longing for the town this person had once known but would now have to use a map to find the right road. ââ¬Å"Labyrinthâ⬠, more likely to be found in Greek mythology, describes a maze almost impossible to escape or find your way around. Here this metaphor displays the extent of the damage done to the town.So devastated and unrecognisable that a person who, presumably, had lived there most of their lives could get lost. Overall the poets use metaphors and enjambments to allow the reader to empathise with the subjects of the poems allowing us to see how the consequences of war would have affected them. I personally found Carsons use of contrast and reference to Greek mythology particularly evocative, letting us see the scale of devastation caused by war.

Can a practice of world civic politics really change the nature of Essay
Can a practice of world civic politics really change the nature of discourse on environmental issues Discuss one issue w - Essay Example This involves the human activists who make policies and form groups through which policies are passed by changing the public values and ideas, empowering the local communities as well as imparting pressure on corporations. The method is mainly effective as the activist groups use it to ensure that environmental policies are passed. World civic politics- effects on environmental issues World civic politics can to a great extent change the nature of discourse on environmental issues. The civic politics can only be effective in a society and this forms the environment where the people live. This first focuses on the understanding of the social and cultural values that the people hold and bring so that it bears on the environment. It also involves the environmental issues faced and how the society mobilizes these values to forge environmentalism, form and sustain programs as well as create movements of environmental action in their communities (Gabriela, 2010). Besides this, it involves an understanding of the variations in cultural and political contexts which involves the differences in the environmental goals and objectives of peoples in different parts of the world. Environmental issues relating to various countries have been challenged by many states especially the issue of global warming, overpopulation and the effects it has on the environment, overgrazing, urbanization among others. World civic politics has come up to challenge and face this issue and this has so far worked, alongside facing many challenges. The main focus here is on the environmental justice. This follows the idea that everyone has a right to fair treatment in terms of the formation and the enforcement of the laws relating to the environment, regardless of their color, race or origin. This means that the various societies needs to have a better environ to live and is important in regard to formulation of the policies. Most impoverished and minority areas live in the populated regions of th e world and these policies seek to ensure that there is environmental justice to all people. Most activists groups involved with the changing of the course of the environmental effects use the direct action (Shannon, 2010). This involves the change of public values through policy making that are passed through advertising media like the televisions and magazines. This is commonly the first step after policy making since it is believed that changing the public ideas about a certain policy is mainly the original step of getting it passed. Environmental values are diverse and various governments deal with the issue of environment differently (UNEP, 2007). Population increase has had a major impact on the environment leading to massive environmental degradation. This is impacted by the effects which involve, urbanization, depletion of the natural resources and overgrazing especially in the developing countries of the world. The effects of this are a drawback in the economic development of these third world countries and a consecutive drop in the balance of payments and trade. Introduction of policies to control degradation in these countries brings a question of their adoption which may result to conflict and tension. For instance, in china, the values of laid-off workers contrasted those of the governmentââ¬â¢

Washington D.C as a world city Essay Example | Topics and Well Written Essays - 500 words
Washington D.C as a world city - Essay Example This directly influences the social condition in the society and acts as a primary driver for social inequality. (Gibel, 2007) The problem with Washington has been the issue of Native Americans Versus the African Americans. A research work conducted at MIT and the Chicago University revealed that the filtering of candidates for issuing jobs was done based on whether the applicant had a white sounding name or a black sounding name and around 60-65 percent of applications were rejected in the case of blacks. Jews marched on Washington against racism on 20th of April 2002 (nkusa.org, 2002). The Jewish leader Rebbi Weiss delivered a speech on ethnic equality mentioning the advantages of social equality in the society and its affect on the all round development of the city. Not only this, the plague of racism even affected the law protecting bodies like the police, fire and municipal services. Police officials exchanged hundreds of racist messages through E-mails including segregated grou p meetings (adversity.net, 2005). In 2001 about 10 percent of the police force is involved in the investigation for law violation (adversity.net, 2005). The Racial discrimination in the society of Washington follows the models of racism. Individual racism where a person acts in such a way to degrade others based on race like a boss not hiring or promoting an efficient worker on the basis of race etc (William, 2002) were common. The lack of proper parenting for and injecting the evil thoughts of racism into children are resulting in racial discrimination in schools and colleges. The environment of social grouping also has a major impact. The differences in the power and influence are easily seen in the majority section of society (William, 2002).These racist policies embedded at organizational level is structural racism. The American psychiatric association stated that racial discrimination affects the mental health of a person and leads to further mental

ISSUE DEVELOPMENT(Cutting Academic Programs in Higher Education) Research Paper
ISSUE DEVELOPMENT(Cutting Academic Programs in Higher Education) - Research Paper Example Therefore, professionals have an array of viable remedies such as decreasing the expenses of the institutions while promoting performance accountability, raising tuition and the most adequate one (in terms of fund management) cutting academic programs (Goldstein, 2005). Cutting academic programs focuses on fronts such as reducing the amount spent on paying faculty and other personal (Keppler, 2010). Another area is merging or total annihilation of departments (Keppler, 2010). According to Ohio Board of Regents (2010), cutting academic programs is necessary especially when one considers the performance of a given program against their financial viability. Various states have seen the effects of cutting of academic programs due to budget cuts. With the projection that Missouri by the fiscal year 2012 would suffer a budget deficiency of up to $500 million, cutting education programs was no longer an option. Given statistics on student enrollment, number of graduates and the value of rel ated research, over 70 programs were in the line up for possible cuts (Chapman et al, 2010). The scenario was more somber in states such as Louisiana where whole colleges were at the risk of extinction. Chapman et al report that in New York and Illinois, administrations were more specific to the point of exuding some form of bias (2010). In the University of Illinois, it was the institution of aviation. The director of this institution cites unfairness given that the institution is small and remote. Meanwhile, in New York State University, the department of Language, Literature and Cultures took the hardest blow with an estimated four programs targeted for budget cuts (Chapman et al, 2010). There are a number of factors that cause states and institutions of higher learning to favor cutting of academic programs even with the public outcries. Currently, increase in cost of living makes it difficult for parents to afford hiked tuition fees hence parents may support cutting academic pro grams to increasing tuition fee (Goldstein, 2005). On the other hand, the institutionsââ¬â¢ administration would rather loose a few programs than loose graduate enrollments because of insufficient funds to run the entire institution (Gold, 1995). After all, students can always move away from a cut program and limit themselves to those available. Finally, there is a great shift in educational stratification in view of changing world economics (Jung & Milton, 2007). The current employment market favors professions in fields such as business (Jung & Milton, 2007) while other programs such as history and arts take a back seat. As such, students prefer engineering and scientific courses at the expense of arts making these programs more susceptible to budget cuts (Jung & Milton, 2007). All these factors contribute to the popularity of cutting academic programs in higher education. Current and Future Prospects: The first issue that comes to mind is the redundancy of some of the academic programs not because of reduced enrollment in their respective departments but because of budget cuts (Chapman et al, 2010). For instance, in New York, foreign languages, classics and theatre are at the verge of ââ¬Å"deathâ⬠according to the article by Chapman et al (2010). It seems the state administrations current shift in budget allocation will become permanent. Most states now favor performance based funding (Harnisch, 2011). The outcome of this is that institutions

Case Study Essay Example | Topics and Well Written Essays - 1500 words - 10
Case Study - Essay Example Leaders create visions and goals whereas the managers and administrators work towards achieving them. The fast changing pace of the technology can be observed in the study of the organizations and the changing role of leadership within the organizations. The role of leaders, managers and the administrators of the organizations become more challenging when new technologies are introduced in the organizations. The good leadership ensures effective communication with the employees with shared vision of the new technology, thus promoting better understanding among the employees for easy changeover. The managers and the administrators need to be guided by the group leaders within the organization to implement the changes in a smooth manner. In the contemporary environment of competitive business, the leadership style and leadership initiatives become major propellant of gaining effective leverage against business rivals. Discussion of leadership with reference to large organization is as important as that of small one for the simple reasons that the leaders within the organizations, not only provide an intangible stability among the employees and facilitate integration with the system, but they have been known to promote collective vision of the organization and provide the necessary impetus to the employees to strive towards it. Scholars assert that in the increasingly changing environment of global competitiveness one needs to ââ¬Ëapproach managerial leadership as a relational, ongoing social construction process rather than as a single clear cut phenomenonââ¬â¢ (Sjostrand and Tyrstrup). The emerging new managerial leadership has encompassed a very important aspect of organizations, that of making effort to involve employees in the decision making process. The leadership has recognized the importance of peopleââ¬â¢s participation in the overall strategy of having collective goals through shared

Why do we look after children Essay Example | Topics and Well Written Essays - 3000 words
Why do we look after children - Essay Example Through their research they have show that humans, like primates, share many similar patterns and evolutionary traits with respect to parenting as a means to increase survival. Are we really that different? See Figures 2 and 3 in the appendix at the rear of the paper. Geary and Flinn (2001) assert that ââ¬Å"at a social and behavioural level these characteristics function to allow individuals to gain access to and control of the associated resources, such as food, mates, and territoryâ⬠(pp. 6-7). The main impetus that holds us from achieving this is largely dependent upon the behaviours exhibited by others of the same species. This complex nature which we call social behaviour is nothing more than the evolutionary process we, as humans, have undergone as a means to achieve this. The only difference is the complexity of the social competencies that a species possesses. As an example, both gorillas and chimpanzees social competencies have evolved so that a great portion of their sustainability lies in their ability to protect their young from other males within their respective species Regardless of the complexity of social competences, humans, as with primates, share one common goal and strategy. ââ¬Å"The ultimate function of parental behaviour is, however, the same: to provide a social context that enables the acquisition of sociocompetitive competenciesâ⬠(Geary and Flinn, 2001, p. 7). As we have evolved we have adapted to this by means of developing social groupings and ties that assist us in ensuring survival through a cooperative effort to gain the needed resources to assure our sustainability. Figure 4 in the appendices displays what Geary and Flinn demonstrate as the unique characteristics of man as we have evolved. In the following pages we will examine the question ââ¬Ëwhy we look after children?ââ¬â¢ through examination of the various factors, both psychologically and biologically, that have enabled us to survive as a species, perpetuate our

Maintenance Management of Engineering Assets Assignment - 1
Maintenance Management of Engineering Assets - Assignment Example Ventilation systems allow for the supply of air into the building and cooling in normally necessary to lower the temperatures The boilers: The boilers normally produce water that is hot and in some instances produce steam to be distributed in the space within which the system operates. This is achieved either by the use of coils or the use of water pipes leading to the radiator of the HVAC system. The chiller: This is the cooling component of the system. It is normally treated with air that is normally blown over the coils carrying the chilled water in the space of operation for cooling to take place through the ventilations. The fault tree analysis (FTA) can be used to analyze the major faults that are likely to occur in the HVAC system. The major faults that are likely to be encountered in the system can either be controller based or mechanical faults. The FTA diagram below analyses these faults. Control faults of the HVAC system occur in the functional components of the system. The faults can be in the form of variations in the thermal conductance of the fluid in the coils, dehumidification faults and non-linearity in the variation of the control system. These faults in the control system can only be solved through maintenance operations of the system. This is a procedure that is used for the evaluation of the various aspects of a functional system so that we are in a position to identify the critical failures that are likely to occur in the system so that we can be able to minimize or eliminate them through correction of designs. The main objective of Failure Modes and Effects Analysis (FMEA) is to make a determination of the parts that have the highest probability of failing in an assembled system (Salsbury, 2003). The process of Failure Modes and Effects Analysis (FMEA) starts with the smallest components of the system and
