Negotiating Reality: Studying Neurons In Denial :: Biology Essays Research Papers

In contrasting the articles I read with explore this paper, I saw an unmistakable polarity between the manners by which the marvels known as anosognosia was drawn closer, a sort of paired: mental versus neurological. The previous appear to me, however not exactly enchantment, to have that equivalent trace of deliberation, while the last are significantly more useful and reasonably conceivable...that is, they are theories which are firmly established in the neurobiology of the mind, speculations which are falsifiable and, subsequently, more remarkable than those which make darken references to obscure and inconspicuous mental procedures. The suggestions which neurobiological speculations, whenever demonstrated to be exact, would have are many; before investigating them, be that as it may, I will initially talk about this refusal of sickness, (3) which is in itself captivating. Anosognosia is a turmoil happening in about 5% of patients who have had a stroke influencing the correct side of their cerebrum (6), specifically the privilege parietal cortex, causing left hemiplegia (loss of motion of the side of the body inverse to the influenced side of the mind). Its trademark highlight is the failure, or, some would state, reluctance of patients to see their own loss of motion, and in outrageous cases, that of others. It is imperative to take note of that anosognosia happens just when the correct side of the mind is included; the impacts of harm to one side of the equator are, as will be clarified later, very unique (1). Dr. Vilayanur Ramachandran of UC San Diego has made anosognosia one of his essential foci of research and has proposed captivating, neurological speculations concerning what may be going on in anosognosiacs' cerebrums. In his exploration, he has discovered that anosognosiacs don't deny loss of motion just in light of the fact that their mind harm makes them be ignorant of the left half of their body; when consideration is attracted to a deadened appendage, by requesting that patients perform straightforward engine errands, for instance, anosognosiacs will either state that they are to be sure completing it (when they clearly are not) (1,2,4,5,6) or make up stories to clarify it away, asserting, for instance, that their joint pain is misbehaving and that they consequently don't want to do it (1,2). As a rule, patients won't perceive the incapacitated appendage as their own, tolerating the unusual and silly ramifications such an announcement carries with it (e.g., the appendage having a place with a family member, their primary care physician having three arms) as very typical (1).

After six days, its airplane supported in vanquishing Japanese Operation Ten-Go and sinking the warship Yamato. For the following two months, Hornet switched back and forth between leading negative marks against Japan and offering help for Allied power on Okinawa. Trapped in a tropical storm on June 4-5, the bearer saw around 25 feet of its forward flight deck breakdown. Pulled back from battle, Hornet came back to San Francisco for fixes. Finished on September 13, not long after the wars end, the bearer came back to support as a component of Operation Magic Carpet. Cruising to the Marianas and Hawaii, Hornet helped return American servicemen to the United States.

World Development Affection

Question: Examine how subjugation and/or different types of constrained relocation influenced world turn of events. Answer: The term constrained relocation has been depicted by the International Association for the Study of Forced Migration (IASFM) as the developments of evacuees, inside dislodged individuals and individuals uprooted from their unique home by normal or ecological wonder or formative ventures. Allen (2012) saw the power movement as the wide-range, mind boggling and intrusive arrangement of wonder. Studies have - recognized three kinds of easygoing components of movement. These components incorporate clash, improvement strategies and ventures and any sort of debacle. The constrained relocation is initially a French word, which means evacuating and alluded to the development of the individual or a gathering of people from the home or the environment. In the event that a gathering or individual is moving inside the nation, it is known as the inside dislodged individual (IPD). It is identified with savage pressure and the alluded to the term uprooting. From the perspective of Anner (2012), the relocation is considered as automatic during the physical vehicle of the individual from a nation and there is no extent of getaway from the people moving the person. Development under danger incorporates the intentional components as long as there is chance to escape from the piece of the nation. Relocation and exiles all through the recorded period has significant effect on the advancement of universes economy and social structure. There are a few reasons for movement. Catastrophic event is one of the reason for uprooting or relocation of populace. It may prompt transitory or lasting dislodging of a gathering of occupant from a territory, where the cataclysmic event has been happened, and the endurance procedure becomes relocation. The constrained relocation in the new area brings about dislodging of whole populace and it turns into the social test to the network and government (Ayenagbo 2012). The term condition incited displaced person speaks to the constrained individuals for leaving their customary inhabitant for the ecological interruption like natural, physical or synthetic change in biological system. Different reasons for relocation incorporate venture advancement, natural issues, escaping mistreatment, human dealing, subjugation, political, common war or strict clashes (Bank 2013). These three classifications of constrained movement are regular subject of scholarly research by various scholastic networks. The outcomes of constrained relocation have been recognized by the administrative, between legislative and non-legislative offices. Struggle incited dislodging is alluded to that movement which incorporates constrained relocation of individuals and the state specialists are unequipped for securing them. The model can be the common war, summed up viciousness and abuse on grounds of race, religion, political supposition and religion. At the hour of Cold war, there has been a development of number of contentions - over the world (Black 2012). Toward the finish of the virus war, there was additionally emotional increment in recurrence of inside uprooted people (IPDs) and they are right now more than the quantity of worldwide evacuee populace. Improvement actuated uprooting can be alluded to those individuals who are compelled to move out of their living space because of the activities or approaches. Models incorporate foundation ventures like dams, ports, streets, air terminals and so on. These sorts of relocations influence indigenous and ethnic minorities and the poor urban or provincial populace for the most part (Chowdari 2013). Catastrophe initiated dislodging is the class of constrained movement, which is because of the cataclysmic events like floods, volcanoes, tremor, and deforestation alongside human-made debacles. This sort of relocation alongside the human populace likewise influences horticulture (Brennan and Packer 2012). This sort of movement or dislodging is influencing a large number of individuals consistently all through the world. Various distinctive global associations help these influenced individuals by cataclysmic events like International Federation of Red Cross and Red Crescent Societies (Eltis Engerman et al. 2011). Advancement prompted removal happened all through the world, yet China and India are two most significant nations in this unique circumstance. As indicated by Chakrabarti and Chatterjee (2012), the resettlement in China uprooted 45 million individuals by improvement extends in the nation inside 1950 to 2000. The dislodging inside India from dam ventures uprooted 21 to 40 million individuals. It was evaluated that 127000 individuals were dislodged during the task Narmada Sardar Sarovar Dam Project (Eltis Engerman et al. 2011). It has been assessed that, formative relocations influenced economy of the nation too. Constrained relocation is happened during huge disturbance of food gracefully, wellbeing administration and asylum. The fast improvement of individuals under wellbeing administration branch of the region, where swelling of transients happen, makes the wellbeing administration unfit to adapt to the convergence of uprooted individuals, which lead to mortality and bleakness in settlement territories. In 1994, 7 to 9% Rwandan evacuees kicked the bucket in the North Kivu locale of eastern Zaire (Chowdari 2013). The uprooted vagrants confronted a higher unrefined death rate than the non-dislodged populace during the hour of complex crises. The weakness of these vagrants is because of the loss of interpersonal organizations and their own benefits, absence of information on the new settlement territory, absence of information on the neighborhood language, diminished access to the medicinal services administrations, deficient haven, absence of sterilization, diminished food and water security . Movement is one of the significant issues in Africa. The aftereffects of movement can be seen as the basic piece of work markets. During most recent couple of decades, in various pieces of world, movement has been occurred with various structures. The movement has been played hooky and ability constraints and existed inside the assorted land and segment settings. Relocation in that sort of circumstance end up being significant work system for the transients, particularly for the poor families, who try to broaden their wellspring of salary (Eltis Engerman et al. 2011). Estimation uncovered 20 to 50 million vagrants in Africa; in any case, the measurable information on relocation streams and related information uncovered undocumented streams. Confirmations demonstrated examples of inward relocation, which has been affected by financial emergency and basic change. In some cases, negative consequences for country employments have likewise been distinguished. Vagrants to Europe and United States were for the most part taught people, who offered ascend to the huge spotlight on cerebrum channel issues. The Sub-Saharan Africa watched the progressions of constrained transients which included inside uprooted individuals and dealing victims. While relocation was the key factor for forming settlement examples and employment, the word related enhancement in provincial parts was connected to portability. In Africa, late investigations uncovered that, 50 to 80 % provincial inhabitants have in any event one transient part with upgraded inclusion of autonomous ladies (Fede 2012). The first and second world wars emergency had significant effect on movement. Muslims moved from Balkan to Turkey and Christians relocated towards different ways during Ottoman Empire breakdown. During 1915, the Ottoman government jumps on the methodical obliteration of the inhabitant Armenian populace. This segregation proceeded till the substitution of Ottoman Empire by the Republic of Turkey in 1923. In 1915 Ottoman state was accounted for with 2,000,000 populaces and the estimation uncovered one million out of 1918, when many thousand individuals became destitute and stateless exiles (Franklin 2012). In 1923 around the whole Armenian populace of Anatolian Turkey withdrew. The Russian Civil War constrained 3,000,000 Russians, Germans and Poles to relocate out from New Soviet Union. The Decolonization followed constantly World War prompted relocation too. The Jewish people group were shaped from automatic and deliberate transients all through Europe, Middle East and Mediterranean. The relocation to the British Mandate of Palestine was improved after the Holocaust and it turned into the advanced Israel state, which was the consequence of the United Nations Partition Plan for Palestine (Goings et al. 2012). The greater part of the European pioneer economies in America inside the time of sixteenth to nineteenth century were subject to the African works moved as slaves for their endurance. The European provincial authorities talked about that; found plenteous land was pointless without sufficient work power to investigate the land. In this unique situation, they favored abuse of subjugation framework, be that as it may, the European or Native American were lacking for the assignment (Greene 2011). The trans-Saharan slave exchange provided Africa work for chipping away at sugar ranches in the Mediterranean then again the Russian slaves and Balkans were additionally included. This slave exchange sent 10000 slaves for each year for serving proprietors in North America, Middle East and Iberian Peninsula (Chakrabarti and Chatterjee 2012). They turned into the significant work power in Western Hemisphere and turned into the mind dominant part of the frontier populaces in the America. 6.5 millio n Immigrants made due subsequent to intersection the Atlantic and settled in the Western Hemisphere inside 1492 to 1776, inside them 1 million were European. The staying 5.5 million slaves were African. In sixteenth and seventeenth century the benefit produced using the products created by Brazil and American nations were utilized to buy more slaves for reinforcing their economy (Hamada 2012). While thinking back to the advancement of development in mankind's history, it very well may be seen that, it is essentially set apart by the shocking violations. One of the noteworthy and solidified chronicles was the record of the African bondage; least 10 centuries of subjection profited Muslim nations, since ninth century to nineteenth century (Ch

Fortification of Solitude is the narrative of racial strain and this paper will concentrate on dissecting this subject and how this book identifies with the American Dream.

Despite the fact that Dylan is white and his companion Rude is dark, the two young men share comparative preferences for music and comic books. Dylan is a white child living amidst a dark network in Brooklyn and simply like different kids in the local he goes to the government funded schools. Dylan’s youth is shown as one loaded up with â€Å"public humiliation, burdening, and bullying† (Lethem 3).It is evident that there exists a racial strain between the general public, Rude and Dylan and subsequently their relationship must be stayed quiet about. Dylan’s encounters while growing up gives an away from of racial strain; he and his folks Abraham and Rachael have a place with the â€Å"self styled improvement project† that is driven by a white lady named Isabel Vendle. As per Lethem improvement implies â€Å"uncool† hence this undertaking exhibits blacks as â€Å"uncool† (12).

The girls’ portrayal in the initial scarcely any lines of the novel shows racial strain; â€Å"the two white young ladies in red vinyl roller skates with white bands on a split blue record walkway appearing as though a match struck in an obscured room† (Lethem 3). This portrayal throws an image of difference among light an d dull in the terms of race. Dylan’s kinship with Mingus Rude can be seen has a post which he uses to triangulate his own racial character. With the way that he is a white kid living in a dark neighborhood whose beguilements incorporate muggings and tormenting, his companionship to Rude is a blessing to him from the sky. In such an area and the way that he is white, Dylan needs a ton of assurance from the blacks; this must be accomplished through get to know Rude who is dark. Actually, Mingus Rude is an old buddy just as a good example to Dylan. Dylan relies upon Rude for assurance and his passageway to control structure of Dean Street. As their fellowship advances, the two young men get pulled in to one another impractically. The strain in racial relations here can be thought as the relationship that is relied upon to exist between a white and a dark; a relationship of ace worker. Racial strain is seen where Dylan becomes friends with another white kid Arthur Lomb to get pas t the school years ordinarily. The distinction comes in where both white young men adopt various strategies towards life. Dylan chooses to go to a white and tip top secondary school while Arthur decides to spend time with dark children. Arthur gets to know Mingus Rude and Robert Woolfolk who become his good examples showing him â€Å"niggerfication.† Dylan accepts that, the complexity found between being dark or white does make a difference even where it is required not to.

Consequently, Dylan copies the dark culture by tuning in to dark music, keeping a â€Å"afro† and having a dark sweetheart (Lethem 56). For this situation, Dylan appears to deny his race therefore causing increasingly racial relationship strains between the dark and the white network. The contradicting incongruity of Dylan being white appears to torment him the vast majority of the occasions. His life as a â€Å"white boy† is met by unlimited embarrassments (Lethem 56). No different, his â€Å"whiteness† additionally manages him a chance to leave the harsh dark neighborhood to a more extravagant and well known one in Vermont. Racial strain is seen where even with white kids encompass him, Dylan doesn't really fit in. at the point when Dylan goes to the school party, he says â€Å"that simple apportionment of move floor funk was a first taste, for me, of something I frantically needed to comprehend: the rural negligence of these white kids to the mind boggling limits of race and music which were my legacy and fixation. No one here minded it was just a danceable song† (Lethem 59). This statement outlines the racial pressures which may exist between individuals of a similar race. Albeit racial relations are the fundamental subject of this book the characters assume jobs that appear to be foreordained. All blacks in the novel are sentimentalized regardless of their fluctuated occupations; whether a mugger or a performer, if the individual is dark, he o she is sentimentalized. As a racial investigation, Dylan bombs when he chooses to enhance â€Å"black cowhide coats and white kid rock† to be a piece of the Stately Wayne Manor band. Oppression the dark network is apparent where Rude is left to be â€Å"a detainee of the streets† (Lethem 66). Now, the peruser can tell that there exists a racial pressure among Dylan and Rude; Dylan shouts â€Å"hey, it’s not bigot to discover blacks sincere as hipsters , wide, and humiliating as a comic book these young men are punks and punks jeer that’s what they do manage it† (Lethem 66).Advertising Searching for book survey on american writing?

Meet Elad Shoushan, a former pro-basketball player in Israel who attended the Technion, Israel’s MIT, got into coding big time, and worked for GE Healthcare. Just before starting at MIT Sloan he founded a little start-up that this year raised over $5 million in Series A funding and whose apps have been downloaded over half a million times. That’s what he’s here to talk about today. Welcome, Elad! How did he get into test prep? [1:55] He’d always wanted to study in the US – even during his basketball career, he dreamed of coming to the US to study and play division I ball. When he was working at GE Healthcare, pursuing his MBA seemed like a natural next step. He struggled with the GMAT, and took it a few times. While he was studying, he thought that the process didn’t make a lot of sense – and he wanted a convenient way to study on the go. He thought an app would be helpful, and so he set out to create one. Going through the test prep process helped him learn a lot about how the brain learns and how standardized tests work. [4:25] As the company has developed, they’ve worked on studying learning methodologies. And they’re getting great feedback from users. What was his career plan when he applied to MIT? [6:10] He wanted to be an entrepreneur. In fact, he’d already spent a couple of months developing/coding the first version of the app (for GMAT prep), and had already left his job at GE. So he’d already launched the business by the time he started at Sloan. His courses at Sloan helped him develop the start-up. He  pursued the Entrepreneurship and Innovation Certificate at MIT Sloan [9:25] What distinguishes his apps from other test prep options? [10:30] The goal is to provide a full educational experience all the way to school, with the focus on being a great mobile learning experience. Other test prep companies basically plug in existing content into an app. His company focuses on the user experience – developing the experience and the content specifically for mobile. They consider what the user needs to learn, where s/he is, when s/he is using the app, to maximize learning in small bites. Is the focus on content or strategy? [13:55] Both. The goal is to identify what the applicant needs to focus on. It’s a comprehensive course: each app has over 1000 questions. For the MCAT course, they’ve partnered with the Princeton Review for content; for the other apps, they’ve developed their own content. The original name is LTG (Label the GMAT)—what does that refer to? [15:40] This goes back to the beginnings of the company, and the idea that solving questions requires two steps – identifying the type of question and knowing the content. The app parses the text so the learner can easily identify the concepts being tested. Now this feature is called â€Å"x-ray†Ã¢â‚¬â€it allows the applicant to see the keywords in the question and quickly understand how the question is structured. It’s a way to grasp the underlying logic of the exam questions. Where does tutoring fit in? [18:35] Tech can help a lot, but it can’t solve everything.

Developing A Warranty Cost Model - Free Essay Example

Chapter 2: literature review. 2.1. Introduction to Reliability: The reliability expression may sometimes be unclear in general logic due to the differences in understanding it among customers. Each customer can define reliability from a different point a view. As an example; a customer may define it as cheap product which has a long guaranteed life cycle period and in the meanwhile works hardly enough. Whereas another customer may define it as a reasonable price product which has a life cycle period and will definitely work as intended. (Institute et al., 1968) The concept reliability is very clear and understandable in the practical and industrial world. Reliability of a product, process, or system is the probability that it will perform as specified, and under certain condition, for a specified period of time.(2Blank, 2004) Reliability is known as the likelihood of a product, machine or a component, to keep doing its intended task without breaking down under precise conditions for a given period of time. (Yang, 2007) (Yang, 2007) The above expression holds three significant essentials to ensure the full understanding of reliability: To know the planned function or task of a product, machine and component. To know the planned duration specified relating to a product, machine and component. To know the environment surrounding where the product, machine, and component, suppose to be working at. Knowing these three essentials conditions will allow us to estimate the product, machine or component reliability capability from the first instance. 2.1.2. Reliability Engineering Studies: The purpose of reliability engineering studies is to control, or to make sure that a product, machine or component will be reliable under normal operation in a specified studied manner, as well as away from breaking downs. (Smith, 1972) Reliability engineering studies are science used to minimize the outcome effects and possible behaviour which will result in maximizing reliability. There are three necessary conditions to achieve the previous statements: To build a maximum reliability consideration into a product, machine and component, during the design and development stages; this consideration is known to be the most critical point due to its responsibility in inherent reliability. To cut down production process differences; this will guarantee that the process will not deliberately degrade the inherited reliability. Once a product is manufactured. A well maintained operation should be commenced; this will prevent the performance degradation and will extend the product life.(Hartman, 2007) These considerations are presented within a large selection of reliability techniques, as an instance; reliability planning and specification, fault tree analyses, accelerated life testing, degradation testing, reliability verification testing and warranty analysis.(Yang, 2007) 2.1.3. Reliability Main Factors: To judge on the reliability of any product, there are factors should be known, as an instance: Intentional usage or application. Product, machine and component specification. Price. Customer expectations. Level of inconvenience caused by product, machine or component breakdown. 2.1.4. Reliability Measurements: In a view of the fact that reliability is measured by probability or likelihood, any effort to measure it will engage the usage of statistical methods. Therefore statistics are very important tools in relating to reliability studies. (Yang, 2007) 2.1.5. Reliability Formula: Warranty and reliability share the same patterns for an economic sense to be observed. Reliability has been identified as the likelihood of a product to keep performing its intended task without breaking down. R= reliability. P (s): success probability. N: number of attempted trails. S: number of success. F: number of failures. Reliability mainly presents the successes and failures in a process, where a good economic warranty cost model has high accuracy in reliability prediction.

[ONLINE] Available at: https://www.reliasoft.com/newsletter/v8i2/reliability.htm. [Accessed 19 March 2011]. 2.1.6. Reliability Improvement: There are many ways by which the reliability can be affected, below are two ways: Quality is the integration of features and characteristics of a product or a service, to enable us to meet the needs and specific requirements. Repetition of the same task causing financial and labor waste. (6Condra, 2001) 2.1.7. Reliability Applications: Various phases of a power plant such as construction, production and maintenance shall apply the reliability data analysis. Such a data might be (Heyman, 1988)applicable for production planning, benchmarking , trend analysis, plant components improvement, risk issues, RCM , spare parts optimization, Design review , Structural reliability. (Heyman, 1988) Data on existing units can be effectively useful for benchmarking the unit performance, during RCM, failure preventions, the spare parts optimization.(Heyman, 1988) 2.1.8. Reliability Prediction Science: It is considered to estimate the effects of the choices made prior the system is built or put into service. Reliability prediction handles the analysing of products with the help of models better than real systems to supply a solid foundation for testing, analysing, planning, manufacturing, and estimating reliability. An ideal example of reliability prediction is to predict the system of specified design and specified group of components in an ideal working environment. At the end of the prediction the reliability of the same system should be tested in a different surroundings from those which data and prediction were obtained from earlier.(3Blischke and Murthy, 2000) Reliability prediction procedure is attempted at the very first steps of improving a program to hold up the design procedure. Commencing a reliability prediction helps in supplying clear demands of reliability enhancement within the improvement stage, and the knowledge of the possibilities of failure of the equipment in its operation life. The advantage of applying reliability prediction, machinery designs are able to develop, money is saved rather than spending on poor designs and time is preserved concerning testing. A widely used way for prediction the reliability of machinery is based on database usage, however this way is not probable due to variety types of failure rates which dramatically happen to similar products.(Geitner and Bloch, 2006) 2.1.9. Objective of Reliability Prediction: The importance of reliability prediction lies down under several points: The reliability prediction should be implemented as an assurance program in different sections of a plant. Repairing decisions are taken when and where problems appear.(Kececioglu, 2002) 2.1.10. Taxonomy Related to Reliability: Availability: It can be defined as the probability that the component will function at any random time. Mean time to failure (MTTF): The time that elapses until a failure occurs. Mean time between failures (MTBF): It is the average time between failures. It is used for repairable systems. Failure Rate: The failure rate in a time interval which is the probability that a failure per unit time occurs in the interval given. Hazard Function: The failure rate limit as the interval approaches zero.(Pham, 2006) 2.2. Reliability Centred Maintenance: The word maintenance from the engineering point of view is: to take the necessary action to maintain or restore equipment and machinery, or system to determine the practical requirement to achieve maximum validity. This includes corrective maintenance, preventive maintenance, and predictive maintenance. What is maintenance? Definition and Meaning. 2011. What is maintenance? Definition and Meaning. [ONLINE] Available at: https://www.businessdictionary.com/definition/maintenance.html. [Accessed 19 March 2011]. Reliability centred maintenance or (RCM) can be expressed as an advanced study into maintenance, which joins the maintenance of interactive applications, preventive, predictive, and proactive, as well as the formation of plans to make the most of the life of the product, and also to ensure proper function for the product, machine and component at the lowest possible cost.

Preventive Maintenance: Preventive maintenance is the programme of planned maintenance, which aims to prevent the collapse and failure. The main objective of preventive maintenance is to prevent the failure of equipment before it happen. It is designed to maintain and improve equipment reliability by replacing worn components before they fail in practice. Preventive maintenance activities include equipment checks and repairs, partial or complete checks at fixed intervals, oil changes, and lubrication and so on. In addition, workers can record equipment deterioration so they know when to replace or repair defective parts before they cause system failure. It would be an ideal preventive maintenance program to prevent all equipment failure before it happens. Preventive Maintenance. 2011. Preventive Maintenance.

Predictive Maintenance: Techniques help to determine the status of equipments in service in order to predict when you must perform maintenance. This approach offers cost savings over routine preventive maintenance. What Is Predictive Maintenance?. 2011. What Is Predictive Maintenance?. [ONLINE] Available at: https://www.wisegeek.com/what-is-predictive-maintenance.htm. [Accessed 19 March 2011]. 2.2.3. Terms and Goals of Using Reliability Cantered Maintenance: The majority of maintenance organizations classify the goals of using (RCM) by the below listed steps: Scheduling the tasks by its priority. Consider the safety prospective. To be familiar with the machinery capabilities; each type of machinery will have different performance type. Knowing the failure causes; to recognize when the right moment to reduce it is. Using skilled staff; to help out in scheduling priorities. Practicing preventative tasks; to help in knowing the machinery status. Disposing and replacing the damaged components; to ensure the effectiveness of the other related parts. Standards must be identified for each step mentioned above. It is important that the steps are done by the same staff who are responsible of the function and operation of the plant.(Tweeddale, 2003) The conditions to develop a sufficient (RCM) program depend on the success of using the observation and statistical methods, because sometimes both methods depend on each other. 2.3. Failure Mode and Effects Analysis: Mechanical failures are introduced as any significant changes regarding size, shape or material characteristics in a system. The first and main responsibility of any mechanical designer is to make sure that the design produced is capable of doing its function properly, meets the designated life time and most important is to be competitive in the market. Estimating and identifying all possible modes of failure which may restrict the functionality of the design will ensure the success in designing. The designer must be familiar with the variety collection of failure modes presented in the work sites as well as the circumstances leading to it, so the designer becomes ready to prevent failure from occurring once again. The designer should preferably have an on hand experience to investigate predictable failures in a professional manner, thus failures could be prevented in future. It is clear that the failure analysis, prediction, and preventative are significant to be known to every designer.(5Collins, 1993) The term behind the failure can be known as the failure to meet some specific performance measurements. Different between definitions terms such as defects, malfunction, fault and reject are usually vital in comparing causes of failures, as well as in the categorizing and analyzing of provided information. The different between the terminologies is mainly to define the types of failure, reasons, and level of failure. For any introduced definition of failures there are no doubts in introducing reliability. Because the failure is the absent of the specification and so changes in performance capabilities occur. (Smith, 2005) The estimation of the data could be done by two methods, first by using history data; this will enable us to have a look at similar machinery which may had experienced identical problems, warranty data, and customer feedback. Second method is conducted, by using several mathematical methods, models and simulations. Dealing with (FMEA) does not always mean that one way is better or more accurate than the other; both of the methods can be used if applied correctly. The proper way in commencing (FMEA) will result is providing helpful data which can help in reducing the hazards relating to work load in a system, product and service. The (FMEA) is one of the most efficient ways considered in preventative maintenance. The (FMEA) will help in having knowledge about what is suitable correction tasks should be done to keep failures away from happening. An effective and successful (FMEA) system could be recognized by meeting these objectives, first recognize the known and possible failures modes, and then reasons of failures. Schedule the failures modes according to the highest risk level, and finally follow up the work done to ensure the correction of the failure.(Stamatis, 2003) 2.3.1. When and Where To Use Failure Mode and Effects Analysis: The (FMEA) procedure is extensively used in different stages, regarding product designing and manufacturing processes. It offers a well organized structure and an easy way to communicate amongst the team of manufacturers. It can be used as well in developing services which will help production process.(McDermott et al., 1996) Traditional failure modes and effects analysis (FMEA) are mainly used models in warranty cost among other models in the automobile industry. (Majeske, 2003) An essential term to inherent reliability into a product or system is by recognizing the failure causes, and making sure they are removed or that their likelihood of happening once again is low. This thought can be done by conducting tests, or logically by using models. Failure mode and effects analysis is a planned way in clarifying the origin of failures modes, and it is considered to be a sufficient reliability schedule, especially it links to reliability development throughout design stage.(7Denson, 2006) 2.4.4. Hazard and Operability Study (HAZOP): Risk analysis is an orderly and systematic method for Examination system and risk management. In particular, are often used as a risk and operating Technique to identify potential hazards in the system and identify interoperability problems. It assumes that events are caused by the risk of design or operating intentions. This approach is a unique feature of risk and vulnerability to treatment methodology that helps to stimulate the imagination of the team Members when exploring potential deviations. Figure (2) shows a sample of HAZOP system.(Organisation and Safety, 1988) Figure (1) a sample of HAZOP system Hazard Operability Studies (Hazops) 1 of 2. 2011. Hazard Operability Studies (Hazops) 1 of 2. [ONLINE] Available at: https://www.lihoutech.com/hzp1frm.htm. [Accessed 19 March 2011]. 2.3.2. Failure Prevention: Failures are predictable, sooner or later all products, machines and component will experience failure due to many reasons.(Yang, 2007) In any engineering system failures are expected. The effects of failures differentiate from little inconvenience costs to financial drops. Failures happen due to various factors, such as: Bad engineering design. Manufacturing process errors. Insufficient testing. Human mistakes. Poor maintenance. Misuse. In order to reduce failures or breakdowns in any engineering systems, there are some methods should be followed: Identify the cause and the way the failure happened. Identify how many times do the failure tends to repeat. Reliability handles the failure concepts in details via different statistical approaches. Whereas safety tries to study, specify, measure, determine, and analyze the failure.(Verma et al., 2010) 2.4. Introduction to Hazard: The accurate understanding of hazard is appreciated due to its criticality. It supplies us with the base foundation of a system safety. Hazard analysis is conducted to identify hazards consequences, and hazard main factors, As well as to determine the risks facing the system. To carry out hazard analysis in a proper manner, it is essential to recognize what causes hazards and how to define hazards. Understanding the hazard character is an important issue to improve the skills needed to identify potential hazards and their results in a system design.(Ericson, 2005) 2.4.1. Hazard Analysis: This analysis involves describing the complete process first, and then collecting the answers for a set of systematic questions. The purpose is to identify how exactly the deviations from the design can arise.   These deviations are further assessed by any negative effect of their consequences on the safe and efficient operation of the plant.   The assessment would provide a basis for any action to be taken to cure this situation. From an engineering point of view, hazard analysis process is the best tool for analyzing reliability data. It can be used to make conclusions about the reliability of a component. (12002) 2.4.2. Survival Analysis: Survival function, also known as a reliability function of the survivors, is a property of any random variable that maps a set of events, usually associated with failure of some system. 2.4.3. Hazard Rate Function: Hazard rate function can be obtained by an equation which assumes a constant hazard rate. 2.4.5. Bathtub Curve: Figure (2) illustrates the bathtub curve which demonstrates the product failure rate against time. Any product cycle life can be divided into three separate durations: The first duration (early life): This duration where the failure probability is decreased to minimum. . It what happens in the early life of most new products, sometimes the first period is mentioned as the mortality period. The second duration (normal life or useful life): This is represented in the graph by a flat line. Failures and breakdowns happen randomly within this duration. In this period the failure rate tends to become somehow constant. During this period the lowest failure rate is observed, so it is the most appropriate time to make reliability predictions. The third duration (wear out): this begins where the slope starts to rise till the end. This typically happen to products when they get old, thus the failure rate increases. Wear out is usually caused by break down due to various reasons such as physical wear and stress.(speaks, 2005) Figure (2) a bathtub curve. A Brief Introduction to Reliability. 2011.

Statistical Models for Life Data: Statistical models for life data such as weibull distribution, survival analysis and warranty help in producing high accuracy in prediction. The automobile manufacturing having relied heavily on warranty interval in its warranty provision inclines more in reliability and therefore seek such analysis. (Ward and Christer, 2005) 2.5.1. Weibull Distribution: The weibull distribution is named after a Swedish professor Waloddi Weibull. He explained the ability to use the weibull distribution in small sizes measurements and it is easiness to supply an accurate model for a broad data sets. At the beginning of his exploring weibull distribution he faced some obstacles and doubts form his colleagues. However, the weibull distribution has ended now to be widely practised in reliability.(8Dodson, 2006) A reason for the wide spread of the weibull distribution is that it has a large different shapes, which makes it easy to fit any data. Also, it is perfect to show the weakest connection of a product. For example, if a system has more than one part, the weibull distribution will present each failure time of each part at the same distribution no matter how insignificant they are .(Nelson, 2003) Figure (3) is a sample of weibull a distribution plot.

Exponential Distribution: This is the most commonly used distribution in reliability, and is often used to predict the probability of survival to time (t) figure (4) shows a sample of exponential distribution graph.(9Dovich, 1990) Figure (4) a standard exponential distribution graph Continuous Random Variables: The Exponential Distribution. 2011.

Disadvantages and Advantages of Statistical Method: Cost; studying and analyzing a quantity of data of different products within a system are an expensive job. The results revealed are not sufficient enough to build an understanding of the type of maintenance needed in this particular situation. The only disadvantage of the observation method appear is when applying it carelessly and without keeping record of foundings, this will result in mixing up different judgements.(4Chalifoux and Baird, 1999) 2.6. Introduction to Warranty: Warranty is a provision for a seller to provide assurance to a buyer that the product will perform as implied. (Zhou and Tang, 2008) Warranty brings confidence to the buyer; automotive vehicles like any other automated system consider warranty to a buyer. (Wu and Li, 2007) Unlike the quality loss function which assumes a fixed target and accounts for immediate issues, warranty loss occurs during the customer use. (Zhou and Tang, 2008) In automotive industry, data is tracked and analyzed regularly (Zhou and Tang, 2008). The interval can be evaluated on the basis of their costs. The effect of warranty especially in the context of the interval, affects the performance of the company especially if the number of returns on warranty is high. (Wu and Li, 2007) Neglecting the fact that warranty cost is a result of conflict between the customer expectation and the performance of the product, the interval of the warranty liability disturbs the economic sense of warranty. (Wu and Li, 2007) Warranty costs have in many companies been positioned as operational costs. (Ward and Christer, 2005) The impact of warranty in the whole business performance has challenged vehicle manufacturers to develop vehicles that are less costly to repair (Metric: Warranty $s) and are more reliable within a longer period of time. (Metric: annual failure rates, AFR) For this purpose to be done, warranty cost models that make the impact of reliability on cost and costs associated with repair of specific failure modes should be economically healthy. (Wu and Li, 2007) 2.6.1. Warranty Probability: The ratio as Pw is termed as the warranty probability (Ward and Christer, 2005). The warranty probability is the ratio of the number of complaints N against the total number of products Tp. Pw Another factor that is important in warranty cost analysis is the complaint factor. (Ward and Christer, 2005) The complaint factor is the ratio of the actual number of complaints and the potential number of complaints where the actual number of complaints is the number of actual complaints fixed. (Ward and Christer, 2005) The method for calculating the warranty probability depends on product performance and customer expectations. (Wang et al., 2010) The distance of performance is a function of the warranty interval. (Ward and Christer, 2005) It is supposed that as time passes, the distance of performance increases, this is the common feature referred to as mileage. In motor vehicles the time age of the car has been consistently assumed to be a factor representing its use. (Manna et al. 2008) Despite the fact that mileage can be determined, the correlation between mileage and age of the car is strong and positive. (Manna et al. 2008) Since vehicles manufacturing designs and model change with time, the automobile industry prefer attaching warranty to age of the vehicle rather than calibrated mileage. Warranty is a key factor in bringing confidence to a buyer. The higher the warranty time, the more the confidence is the buyer. (Manna et al. 2008) 2.6.2. Warranty Distribution Analysis: Feedback from warranty returns provides a solid basis in determining use failure distribution. (Murthy, and Blischke, 2006) The time interval as a factor contributes significantly to predictions. The warranty intervals are the most solid factor that can be used in assessing the failures prediction. By maintaining warranty and assessing failures for a longer period of time, more knowledge on the performance especially for automated systems is achieved. (Murthy, and Blischke, 2006) Reasons for carrying out warranty data analysis are the following: Forecasting warranty claims. To determine risk assessment and monitoring. Reliability assessment.(12002) 2.6.3. Reduction strategies for cost drivers There are two factors that have been identified as primary warranty cost drivers. The number of occurrence of an event which can be noticed by the analysing failure rate and the cost of the process are the identified cost drivers. (Attardi et al., 2005) The strategies employable for reduction of costs are by reducing the factors. (Attardi et al., 2005) 2.6.4. Cost model in product development The cost model has been used in product development in making economic sense of organizational existence. (Karim and Suzuki, 2005) Through its impact in influence of decision making by providing design alternatives that come handy in warranty cost, the model establishment should be in advisory of the product development through calculation of estimates of product total warranty cost. (Aldridge, and Dustin, 2006) Difference in warranty costs based on design alternatives provides a short projection of the optimized design that maintains both customer confidence through warranty and economic advantage to the organization. (Attardi et al., 2005) Identification of necessary product features, capabilities and diagnostic tools that are required in automobile projected warranty savings for the warranty intervals is achievable through the cost model in product development. (Aldridge, and Dustin, 2006) Under the foundation of the cost model, the risk involved in the warranty interval can be evaluated by analyzing the risk involved in an extension of warranty in automobiles. (Aldridge, and Dustin, 2006) It should be taken into consideration that the cost model economic impact is dependent on the period of warranty especially with automobiles that are known to wear and tear. (Karim and Suzuki, 2005) Chapter 3: case study (from notes given by doctor) Introduction: Field data in the automotive industry often comes in two types, the first is grouped data expressed by months in service. The second is ungrouped data available from company owned but customer operated fleets and expressed as miles to failure. In many scenarios, data which comes from late stages have a greater importance over the former because of the following reasons: Mileage is more objective measure of the component life than time in service. There are types of failures are not tracked by the warranty system. The complexity of censoring mechanism in relating to reliability analysis of grouped warranty data. Therefore, this theoretical case study will focus on the analysing of ungrouped mileage data which is not represented by time in service, because it comes from the company owned fleets. Aim and objective: To discuss a procedure to estimate the censoring mileage and the reliability function for a component of interest (e.g.: battery). Data: Table 1 shows a format of failure data from a customer operated fleet. The vehicle mileage is reported only at failure or service events.
