Use of batteries as power sources Research Paper

Use of batteries as power sources - Research Paper Example The requirements for these batteries comprise high release rates, low insertion loss from components in series by means of the cells, high-precision measurements, superfluous security protection, and no upset by means of incredibly high ESD transients.If we analyzed then we come to know that Battery-pack requirements have gone through a main evolution in the history several years, and today's designs have considerable electronic content.Moreover, practically all Li-ion protector circuits for one- and two-cell applications have protector FETs in the low (unenthusiastic) surface of the battery. Plus key issues exacting to a low-side Li-ion protector circuit are converse. The transients shaped when the Li-ion protector opens throughout a brief short or when the battery is unplugged even as beneath load may exceed the voltage rating of semiconductors in the battery set. This theme describes a number of plan issues and suggests solutions to make your mind up or get better them. Resolution of these subjects requires attention to together the circuit design and the printed circuit board (PCB) explain.If we analyzed the Fig. 1 then we come to know that it is a block drawing of circuitry in a typical Li-ion battery set. It demonstrates an instance of a security protection circuit for the Li-ion cells and a gas gauge (capacity measuring device). The security circuitry includes a Li-ion protector that controls back-to-back FET switches. No doubt, these switches can be opened to defend the pack next to fault conditions such as in excess of voltage, beneath voltage, and over current. If we analyzed then we come to know that the figure also comprise a temperature responsive three-terminal fuse that will open due to long-drawn-out over present or over temperature, or it can be forced to open by superfluous protection circuitry in case there is a responsibility where the main protection circuitry fails to respond. As opening this fuse is a previous resort, as it will render the pack enduringly disabled. The gas-gauge circuitry events the charge and discharge present by measuring the voltage crossways a low-value sense resistor with low-offset dimension circuitry. Furthermore, the present measurement is incorporated to decide the alter in coulometric ability. In adding up, the gauge measures temperature plus voltage, assess gas-gauging algorithms to decide the obtainable capacity in the battery, and computes time-to-empty and additional values necessary by the host. The available capacity as well as additional measurements and computational outcome are communicated to the host over a sequential communication line. A diagram indication of obtainable ability can be displayed by the LEDs when make active by a push-button switch. Fig. 1. Block diagram of circuitry in a typical Li-ion battery pack. OPTIMIZING THE DESIGN FOR MEASUREMENT PRECISION Let's take a look upon measurement precision requires a precise measurement data gaining system and measurement sensor and also need a cautious board layout. Moreover, if the designer does not pay notice to all these items, the ensuing system performance may not transport the expected results. The sense resistor and how it is linked to the data gaining system are dangerous design decisions. The intelligence resistor may see changes in temperature that are much bigger than the ambient difference of the battery pack due to power debauchery in the resistor. Use of a low-temperature coefficient resistor will get better obtainable capacity and current-measurement precision. The effectual sense confrontation seen by the dimension circuitry may depend on how the printed circuit board (PCB) etch is linked to the sense resistor. If the intelligence re

Chinese Language and thoughts - Essay Example It was not that English language did not have the required word in it; instead, it was that I had forgot that word because of my poor memory and small vocabulary. He was at least 20 years older to me, so I did not express my disagreement overtly out of respect for him, but deep inside, I did not feel good about what he had said and I also disagreed with him on the matter. I still disagree with him that our thinking ability depends upon the language we speak. An argument that I found most appealing on one side of the debate was lack of empirical support â€Å"for the view that language determines the basic categories of thought or that it ‘closes doors’† (Wolff and Holmes, 2011, p. 261). Lack of explicit encoding of an ability in a language does not, in any way, deprive people of the ability to make conceptual distinctions. This is elaborated as the English speakers’ ability to tell loose fit from tight even though their spatial preposition system does not encode this distinction. In other words, people are not dependent upon words to understand and describe reality (Pinker, 2007, p. 124). On the contrary, the least convincing argument I found on the other side of the debate was that speakers of a language other than English may be remarkably good at staying oriented â€Å"and perform feats of navigation that seem superhuma n to English speakers† (Boroditsky, 2010) simply because instead of saying â€Å"left† or â€Å"right†, they use phrases like â€Å"theres an ant on your south-west leg† (Boroditsky, 2010) because they do not have words similar to â€Å"left† and â€Å"right† in their language. This sounds unappealing to me because a language that lacks simple and straight-forward substitutes to â€Å"left† and â€Å"right† would confuse its speakers way too much to be rightly guided in complex scenarios where directional guidance is

How does Great Expectations Reflect the Victorian Era?

How does Great Expectations Reflect the Victorian Era? Then, Pip becomes a gentleman, he assumes that great expectations mean that he may no longer be content with the good things he already has. When Mr. Joe visits Pip in London, Pip looks down on Mr. Joe and thinks that he does not fit to his new environment anymore. Pip thinks to himself, Not with pleasure, though I was bound to him by so many ties; no; with considerable disturbance†¦ If I could have kept him away by paying money, I certainly would have paid money (pg.186). Although Joe protected and assisted Pip throughout his childhood and adolescence, Pip was still embarrassed by him. However, in the end he regrets for treating him so rude. After so many disappointments (He was planning to marry Biddy, but she married Mr. Joe. He expected that being a gentleman would provide him a chance to marry Estella, but she married Bentley etc.), he is finally forced to develop some simple and realistic expectations and learns how to be content with the modest living he makes in the mercantile firm. Pip learns that social class is not essential for happiness; that strict designations of good and evil, and even of guilt and innocence, are nearly impossible to maintain in a world that is constantly changing; and that his treatment of his loved ones must be the guiding principle in his life. Great Expectations and Victorian Age Dickens Great Expectations is one of several reflective books of Victorian age. It is a very successful representative of its own time. Written in 1860 and following the story of Pip from childhood to adulthood, the book represents the common Victorian elements like social class difference, industrialization, Victorian houses, Victorian values and women. At the very beginning of the book, we encounter with a typical low-class family. They live in a village among marshes. Mr. Joe is a blacksmith and his wife (the sister of Pip) is a typical Victorian low-class housewife. She sinks under the household duties and always complains about not being able to take off her apron (chapter 1-2). Because of her harsh duties, she is always frustrated and often beats Pip. Then, we encounter with high-class, well-dressed, well-dancing women like Miss Havisham and Estella through the onwards of the book. These two different families are also the first signals of the existence of social classes in the society. On the one hand, Gargery family is a poor, uneducated, living in a village. On the other hand, Miss Havisham lives in a mansion called Satis House. The Pockets house is full of servants. Estella is a young lady who dances well and educated abroad. Also the other women in Pips snobbish life in London represent the typical high-class Victorian women. Having seen the two different lives in early years of his life, Pip wants to shift to the upper class. He expects to become a gentleman who has all the values appreciated by the society in order to have Estella and an upper class lifestyle. Pips early impressions about London remind us the effects of Industrial Revolution and immigration. When he comes to London, he is amazed and displeased with the unbelievable crowd (resulting from immigration for job) and awful smell (coming from sewage due to the factories): I was scared by the intensity of London. I think I might have had some faint doubts whether it was not rather ugly, crooked, narrow, and dirty.'(pg. 138) The gloomy streets of Smithfield disturb him. It is easy to see Victorian architecture and Victorian houses in the book. Satis House, Wemmicks house (like a castle), and other ornamented houses tell us the taste of architecture of those days. It is very sad not to see some of important themes of Victorian era like child labor, prostitution, colonialism etc. in Great Expectations. But, Dickens uses colonialism in Great Expectations as a narrative device. A transported convict exactly meets the need for a benefactor who can make a substantial fortune yet who has to remain anonymous, and of whom Pip will eventually be ashamed. The capital law against returning from transportation sharpens the impact of the later chapters, when Pip sheds his pretensions as well as his wealth. Thus Dickens, like so many Victorian authors who used the colonies as places to transfer burned-out characters or from which to retrieve characters, uses this aspect of colonialism as the dramatic cornerstone for his novel. (Jonah Raskin in The Mythology of Imperialism (New York:Random House,1971)) In other words, colonialism is used not as a theme but a narrative device in Great Expectations. Also, Dickens used the other themes mentioned above in his other works. For example, Oliver Twist child labor, destitution etc.

The Lost Handwriting :: essays research papers

The Unheard Writing   Ã‚  Ã‚  Ã‚  Ã‚  One day, in the second grade, the teacher told our class to get out their lined paper and pencils. As I made that first fancy loop, following the example on the board, I was wondering what possible situation I was getting into. Later in the year, I learned that cursive writing was time consuming and very difficult to master. In high school, I found out that we had a choice of cursive or printing. I asked myself why we needed cursive? Why are others putting aside this writing that consumed so much time? What are the pros and cons of cursive? This type of writing is established, and I never thought to evaluate its effectiveness or its need until now.   Ã‚  Ã‚  Ã‚  Ã‚  One such pro is that cursive an established form of writing. In grade school, we learned how to neatly write the cursive alphabet. The reason that so much time was spent on this area of development is because it is seen as professional writing. The teacher wanted to prepare us for the future, and without this ability we would be unable to read or write this type of writing. For example, many professional forms such as taxes, weekly paycheck and legal papers all require a signature.   Ã‚  Ã‚  Ã‚  Ã‚  Adding on to that, your signature is unique to each and ever one of us. In all the people in the world, there is only one signature that is like yours and that is your own. Yes, it is possible to forge a persons signature, but it is highly unlikely to be a precise copy of the original. For instance, most colleges require students to sign their exams. This procedure prevents the acts of cheating. Moreover, banks have convicted many people of forge checks. A unique signature prevented both of these situations. Who would of thought that personal ID’s were this important?   Ã‚  Ã‚  Ã‚  Ã‚  On the other hand, one negative attribute is the fact that cursive is sloppy. It is hard for many of us to read cursive that was quickly written. It was hard for me to write it neatly in school. It was also difficult to read other kids’ handwriting because all the letters were smashed together and looked almost the same. Recently, there was a lawsuit involving a doctor and his cursive prescription slip. The patient received the wrong prescription. This mishap happened because the doctor was busy and wrote like a speeding bullet.

Compare and Contrast: Hinduism and Islam

Hinduism and Islam: Compare and Contrast It is universally known that religious faiths creates diversity in culture and give new identity and outlook to matters signifying a new way life. In most cases, religious faith is accountable for people’s behavior in conducting daily activities including business, work, socialization, and cultural functions within a specified community. The immensely large majority of the human species has always looked to a higher power for acceptance, love, enlightenment, guidance, and even sometimes discipline.There are many different religions with many different practices and beliefs, however, in this paper I will be comparing and contrasting the belief on who is worshiped as the â€Å"higher power† as well as the diet practices and rituals of the two common religions known as Hinduism and Islam. Hinduism and Islam have been preexisting for a very long time. Hinduism main roots dating back in India and Islam from the Arab world, the two hav e quite a vast number of differences and similarities as well.Hinduism and Islam, other than Christianity, are two out of three major religions followed in the world. It is difficult to spot any similarities between the two religious groups since they are known globally to cause war and chaos wherever they come together. However, the two religions show vast differences beginning from their origins and development. Islam believes that their faith is founded on the faith outline by a prophet of God called Mohammed.Mohammed is the core founder of the Islamic religion since the time he received revelations from Allah. On the other hand, Hinduism began as integration of numerous religious groups in the subcontinent of India where, at the time, there many wonderers, exiled communities, and prophetic individuals. The groups came together to form the contemporary Hindu religion (Anon. , 2013). Most principally, the two religions have a different concept concerning the Supreme Being, God. Th e Muslim believes in the existence of one almighty God referred to as Allah.Allah is given numerous positive attributes by Muslims relating him to greatness, however; Allah is also termed as merciful, the creator of all, the sustainer of all human life, and the incomparable one. This concept that Allah is incomparable has allowed all Muslims around the world, though with diverse cultures and languages, to refer to God as Allah. Moreover, the name Allah is a discrete name from the language Aramaic which is a language historically known to have been the native language of Jesus. This kind of belief and complete trust in the existence of one God are essentially known as monotheism (Naik, 2007).On the other hand, the Hindu believes about the existence of one Supreme Being is contrary to that of Muslims. Hindus practice polytheism which is basically the belief in multiple Gods. The word Hindu has a geographic importance relating to a certain community referred to as Sindhu who lived beyo nd the river Indus in ancient India. It is noteworthy to indicate that the Hindu believes that everything is God starting from the physical elements such as trees, mountains, and rivers to living things such as humans. This in religious education is referred to as Pantheism.While Muslims believe that everything is God’s, the Hindu on the contrary perceives everything as God. In a global perspective, the Hindu has a quite diversified perception of God since every community may have more than a hundred Gods, whereas others believe to a minimum of three Gods. Hindus have come up with an argument that they should adopt and refer to only one God as divine and sacred. This may bring some internal conflicts among the Hindus since the scholars might be compromising with their ancient beliefs and customs (Brodd, 2003, p. 108).However, the two religions agree that man is a manifestation of Gods wonderful creation. This means that all the two agree on is that God or Gods created man and other physical and spiritual creations. Muslims believe that man was created the same in that all men are equal in the eyes and perception of God. In this case, Muslims are against any discrimination on the basis of social status, race, or tribe. Also, Muslims fail to agree that God favors individuals on the basis of wealth and other material properties but favor from Allah is given to anyone on the basis of virtues and piety.On the other hand, Hindus believe that men were created in caste systems, which articulates mankind is not equal. Instead, human beings are categorized into four facets. The firsts group is referred to as Brahmans who represents the highest people in society on the basis of priesthood, wealth and social status, and intellectual abilities. This group is certainly the most respected and adored since everything is God according to Hinduism. The subsequent group, Kshatriya is slightly lower in terms of social class, wealth, and intellectual capabilities since it r epresent the ruling class including warriors and heroes in the society.The third category is referred to as Vaisya a group mainly composed of agriculturalist and artisans in the community. The last group, Sudras includes the lowest ranked individuals in the community probably on the basis of poverty and lack of intellectual abilities. Muslims and Hindus acknowledge that there is life after death since they all believe in the existence of the soul. Also, they both believe that there is judgment after the physical death. In addition, the judgment is based on the deeds and the way a person has lived have or her life.The positive virtues such as humbleness, respect, merciful, and faithful among others are believed to influence positive results from the judgment. However, the concept with which they both perceive life after death is what differs among the two religions. Hindus do not believe in the existence of an awful place formally known as hell, or the existence of heaven. Instead, H indus believe in the power of reincarnation. This means that they believe that a person is born afresh in another life once he or she dies.The reincarnated person will then acquire a new status based on his virtues and attributes of the previous life. This contradicts with Muslims beliefs of the body and soul. Muslims believe that a human being has two destinations either heaven or hell. Heaven is for people who have upheld their belief and trust in Allah with the refection of their deeds. On the contrary is a place of anguish and torture for those who refuse to follow Allah outlined commandments. However, the decision to go to either place depends on the ruling made on the Day of Judgment.Similarly, both religions have a certain animal they are restricted to eat. In Islam, they have all the luxury to eat all kind of meats from cows, lambs, goats, and poultry except pigs due to some beliefs about the unsacred nature of the pig meat. Hindu believes that because food is a gift from Go d, it should be treated with great respect (V, 2000). Hindus do not enjoy the luxury of eating cow meat since they perceive the animal as sacred due to their pantheism nature. Devout Hindus believe that all of God’s creatures re worthy of respect and compassion, regardless of whether they are humans or animals (Elgindy 2005). Therefore, a cow is viewed as divine and sacred hence it cannot be eaten. Hinduism encourages being vegetarian and avoiding the eating of any animal meat or flesh (Elgindy 2005). However, not all Hindus choose to practice vegetarianism, and they may adhere to the religion’s dietary codes in varying degrees of strictness (Elgindy 2005). Also, the two religious groups do pray except that they pray differently.Hindus mostly pray in temples, whereas Muslims usually pray mosques. Hindus temples are usually decorated with various pictures that manifest the being or the nature of their Gods. However, Muslims are not allowed to have any pictures in their mosques since God is incomparable to anything not even the physical representation through pictures. The Islamic religion is founded on the basis of activism which calls for all Muslims to go out to the entire world teaching people to adopt and believe in the faith outline by the Quran, the Muslim Holy Scripture.Therefore, most Muslims are dedicated to teaching their traditions and practices concerning their faith to other tribes and humanity that do not necessarily espouse Muslim beliefs and faith. On the contrary, Hinduism is based on personal principles of tolerance which include patient listening even to non believers. Hindus basically believe it is a matter of time before people reawaken and embrace Hindu principles and their faith. Therefore, Hindus believe that, at the end, all religion in the world will conform to their belief in pantheism.Muslims are very specific to their ritual and religious practices since they observe strict fasting periods to even over five days in spe cial periods such as namaz and roza. Fasting is considered an opportunity to earn the approval of Allah, to wipe out previous sins, and to understand the suffering of the poor (Katme 2009). Fasting is also partly to be in control of appetite and to avoid food addiction (Katme 2009). It is the fourth ritual observance in the Five Pillars of Islam. Also, Muslims wake up very early in the morning, on a daily basis, to pray to their God, Allah.On the contrary, Hindu does not put much effort in religious rituals instead they engage in selfless activities so as to increase their probability of being reincarnated to a higher being. In addition, Hindus belief that God is everything, simply outlines that God can take any form to reveal his existence. Hindus also outline that their view of God shows that God has unconditional love for love humanity and creatures. Therefore, God is not necessarily a male according to Hindus, instead; God can reveal himself inform of a female figure or an anima l.Islam religion believes in the existence of God’s angels who are given the duty to fulfill God’s tasks. In Muslim, God cannot reveal himself in any human or physical form, however; rather than revealing his nature in a divine form he sends angles to protect human beings. Moreover, angles are invisible to the naked eye, and they also do not need human comfort since they are heavenly created hence do not posses human qualities. The two religions are similar in that they are built on the theory of commitment to God. This theory requires all the believers in both religions to trust and obey God without question or doubt.Also, the theory is based on purity and peace supported by unquestionable submission to God. Although, the two religions strictly foster people to trust and obey God, they acknowledge the importance of own will in a personal decision. This means that Hindu and Islam do not force any individual to become one of their own or restrict someone from going into other religions. Instead, followers are given the will to decide whether to stay, or shift to other religious belief, but once an individual decides to stay him or she must follow the religious principle held by the either of the group.Beside, followers are allowed to choose on their own with the consent that their decision and their way of living will be judged or will affect their reincarnation in the next life (Horton & Plunkett, 2002, p. 36). Also, there are other slight but significant differences among the two religions. The Muslim religion is based on a politically built system emulating Mohammed way of living which was essentially based on military power, missionary zeal, and political control. On the other hand, Hindu believes in many Gods is meant to provide spiritual freedom to the followers devoid of political influences.Also, Hindu religion is presented as a more feminine religion rather since the symbol of the cow signifies motherhood and fertility. Also, many Hindu d eities are females and their temples consist of arts full of female figures. Muslim, on the other hand, worship a masculine Allah since most of the women are not allowed to enter mosques, and also women are veiled while in public. There are also different ways to realize the truth in Hindu, whereas Islam’s believes in only one true way (Brass, 2005, p. 119).The two religions outline one another as arrogant and disapprove their faith, on the basis of varied grounds. For many years, there have been various wars and grievances containing the two religions with Muslims killing numerous Hindus in India for destroying their places of worships, Mosques. As seen in the above contest, there are more differences in the nature of the tow religions rather similarities. Hindus and Islam’s disagree on the bases of existence of one God, life after death, existence of angles, and others key areas relevant to religion.However, both religions are built on positive attributes, the theory of devotion to God and acknowledge the importance of human free will. Therefore, there is no place that both religion advocates for war or hatred that have preexisted among the two religions. Since both of the Gods allow positive attributes of love and tolerance, these attributes should be used as a basis for uniting the two religions. Works Cited Anon. , 2013. Diffrence Between net.

Why Youth Leave the Church

Introduction â€Å"With such an army of workers as our youth, rightly trained, might furnish, how soon the message of a crucified, risen, and soon-coming Savior might be carried to the whole world! † (Education, p. 271). Wow, what a statement. This is probably the most well known statement by Sister Ellen White concerning the youth. These words are so powerful and motivating, that they inspire the imagination to look forward to it’s fulfillment, to the day when this army of dedicated Christian young people will be spread out around the world to bring the message of Jesus’ soon return to everyone.I must confess that simply the thought of this sends shivers down my spine. I am, however, forced to question whether this dream will ever become a reality. The church, it seems, is facing a dilemma, in that we are losing the youth. Many of our young people are leaving the church, and in seeking to answer the question of why this is happening, I would like to share with y ou the resource that I believe to most accurately describe the reason for the youth leaving the church, as well as what to do to stem the flow of this widespread desertion. Recommended Resource(s)The main resource that I believe to be the best and that I would like to recommend, is the book, Why our Teenagers Leave the Church, written by author Roger L. Dudley. I will also be referring to two other resources that I used, both of which is based on the above mentioned book. The first and most important is an article with the same title, and by the same author. It is basically a condensed version of the book, and it covers the basics of the research done, as well as the results and what can be done to prevent the youth from leaving the church. The second is a sermon by Pastor Dwight K.Nelson, titled, Primer for the next generation: XNY 101. In the sermon Pastor Nelson briefly explains how the study was done, the results attained, and the remedy to the problem. I will now proceed to dis cuss the two secondary resources (Article: Why our teenagers leave the church; Sermon: Primer for the next generation: XNY 101), based on the premise of the primary resource (Book: Why our teenagers leave the church). Primary Resource Roger Dudley’s book is the culmination of an expansive 10 year longitudinal study, where the author traced the lives of about 1500 teenagers as they grew up and, often, grew disillusioned.According to his book, Dudley asserts that 40 to 50 percent of Adventist youth leave the church before their mid twenties. Secondary Resources Why our Teenagers leave the Church (Article) As was mentioned previously, the article is a very condensed version of the book, and it goes straight to the point. The purpose of the study was to attempt to discover the extent of the church’s loss of it’s young adults. According to the article, 40 to 50 percent of baptized Seventh Day Adventist teenagers either dropped their membership, or became inactive in the church, in their mid twenties.According to Dudley, there are five influences that determines the continuation or discontinuation of young people in the church, and they are as follows: Home Influences Parochial vs. Public Education Congregational Involvemnet Lifestyle Standards Devotional Practices I am in favor of, and recommend this resource, because it is straight forward and to the point. It provides the needed facts right from the start, allowing the reader to look at the all the determinants and then make a plan on how to proceed to negate or minimize the loss of young people.Primer for the next generation: XNY 101 (Sermon: Audio) Pastor Dwight K. Nelson starts of by explaining the details of the study that was done. He quotes the following from the book: â€Å"Many teenagers and young adults are leaving the church because they perceive it to be behavior centered when they are looking for relationships. † (Why Our Teenagers Leave the Church, P58) â€Å"We have seen that though our youth have heard the words of the gospel of righteousness by grace through faith, . . . [our] emphasis on behavioral standards has led the majority to believe that they must somehow merit salvation. . . Through precept and example, we must do everything possible to clarify grace and to break the hold of legalism. We must communicate a gospel of hope. Without this effort we will never retain our youth. They will not continue to struggle in a contest that they cannot possibly win. † (58, 59 emphasis supplied) I would also gladly recommend this resource, because Paster Nelson identifies the problem from the data, and he then goes on to provide a remedy to the problem. Conclusion â€Å"We cannot always build the future for our youth, but we can build our youth for the future. † Franklin D. RooseveltWhen looking at the data covered in these resources, it is clear that the future is uncertain. It is also clear that the youth are the leaders of tomorrows churc h, and in order for them to lead, they need to be there. We need to realize that we cannot necessarily set everything in place for our youth, but, what we can however do, is to prepare our youth for the future, for the decision’s that they will have to make. We can prepare them for this uncertain future by laying a good foundation in our educational institutions, at church, and most importantly at home. The greatest determinant, by far, is the family.If the family is built on the rock, nothing can shake it. â€Å"With such an army of workers as our youth, rightly trained, might furnish, how soon the message of a crucified, risen, and soon-coming Savior might be carried to the whole world! † (Education, p. 271). — Reference List Ellen G.
