An Explanation of Unicode Character Encoding

An Explanation of Unicode Character Encoding For a computer to be able to store text and numbers that humans can understand, there needs to be a code that transforms characters into numbers. The Unicode standard defines such a code by using character encoding. The reason character encoding is so important is so that every device can display the same information. A custom character encoding scheme might work brilliantly on one computer, but problems will occur when if you send that same text to someone else. It wont know what youre talking about unless it understands the encoding scheme too. Character Encoding All character encoding does is assign a number to every character that can be used. You  could make a character encoding right now. For example, I could say that the letter A becomes the number 13, a14, 133, #123, and so on. This is where industry-wide standards come in. If the whole computer industry uses the same character encoding scheme, every computer can display the same characters. What Is Unicode? ASCII (American Standard Code for Information Interchange) became the first widespread encoding scheme. However, its limited to only 128 character definitions. This is fine for the most common English characters, numbers, and punctuation, but is a bit limiting for the rest of the world. Naturally, the rest of the world wants the same encoding scheme for their characters too. However, for a little, while depending on where you were, there might have been a different character displayed for the same ASCII code. In the end, the other parts of the world began creating their own encoding schemes, and things started to get a little bit confusing. Not only were the coding schemes of different lengths, programs needed to figure out which encoding scheme they were supposed to use. It became apparent that a new character encoding scheme was needed, which is when the Unicode standard was created. The objective of Unicode is to unify all the different encoding schemes so that the confusion between computers can be limited as much as possible. These days, the Unicode standard defines values for over 128,000 characters and can be seen at the Unicode Consortium. It has several character encoding forms: UTF-8: Only uses one byte (8 bits) to encode English characters. It can use a sequence of bytes to encode other characters. UTF-8 is widely used in email systems and on the internet.UTF-16: Uses two bytes (16 bits) to encode the most commonly used characters. If needed, the additional characters can be represented by a pair of 16-bit numbers.UTF-32: Uses four bytes (32 bits) to encode the characters. It became apparent that as the Unicode standard grew, a 16-bit number is too small to represent all the characters. UTF-32 is capable of representing every Unicode character as one number. Note: UTF means Unicode Transformation Unit. Code Points A code point is the value that a character is given in the Unicode standard. The values according to Unicode are written as hexadecimal numbers and have a prefix of U. For example, to encode the characters we looked at earlier: A is U0041a is U00611 is U0031# is U0023 These code points are split into 17 different sections called planes, identified by numbers 0 through 16. Each plane holds 65,536 code points. The first plane, 0, holds the most commonly used characters and is known as the Basic Multilingual Plane (BMP). Code Units The encoding schemes are made up of code units, which are used to provide an index for where a character is positioned on a plane. Consider UTF-16 as an example. Each 16-bit number is a code unit. The code units can be transformed into code points. For instance, the flat note symbol â™ ­ has a code point of U1D160 and lives on the second plane of the Unicode standard (Supplementary Ideographic Plane). It would be encoded using the combination of the 16-bit code units UD834 and UDD60. For the BMP, the values of the code points and code units are identical. This allows a shortcut for UTF-16 that saves a lot of storage space. It only needs to use one 16-bit number to represent those characters. How Does Java Use Unicode? Java was created around the time when the Unicode standard had values defined for a much smaller set of characters. Back then, it was felt that 16-bits would be more than enough to encode all the characters that would ever be needed. With that in mind, Java was designed to use UTF-16. The char data type was originally used to represent a 16-bit Unicode code point. Since Java SE v5.0, the char represents a code unit. It makes little difference for representing characters that are in the Basic Multilingual Plane because the value of the code unit is the same as the code point. However, it does mean that for the characters on the other planes, two chars are needed. The important thing to remember is that a single char data type can no longer represent all the Unicode characters.

The Meaning of -N Desu in Japanese

The Meaning of '-N Desu' in Japanese The phrase –n desu (ã‚“ 㠁 §Ã£ â„¢), meaning it is, is sometimes used at the end of a sentence. It is also commonly used in conversation, though it might be difficult for beginners to learn. The phrase has an explanatory or confirmatory function. The difference between –masu (ã€Å"㠁 ¾Ã£ â„¢), another nominal ending for a verb, and  Ã¢â‚¬â€œn desu is very subtle. This makes it very hard to translate. The nominal ending  Ã¢â‚¬â€œn desu can be translated as it is the case that or it is for the reason that. However, there is no true English equivalent. –N Desu Versus –Masu One of the best ways to understand the subtle, nuanced meaning of –n desu is to compare it to  Ã¢â‚¬â€œmasu  by viewing how two sentences use these endings differently: Ryokou ni iku n desu ka? (りょ㠁“㠁† 㠁 « 㠁„㠁  ã‚“ 㠁 §Ã£ â„¢ 㠁‹ã€‚) Are you going to travel? Ryokou ni ikimasu ka? (  Ã£â€šÅ Ã£â€šâ€¡Ã£ â€œÃ£ â€  㠁 « 㠁„㠁 Ã£  ¾Ã£ â„¢ 㠁‹ã€‚) Are you going on a trip? In the first sentence, which uses –n desu, the  speaker assumes that the listener is going on a trip and just wants her to confirm it. In the second sentence, which uses –masu,  the speaker simply wants to know if the listener is going on a trip or not. Formal Versus Informal You also need to use a different form of  Ã¢â‚¬â€œn desu when it  is attached directly to a plain form of the verb in an informal situation. When the circumstances are informal, use –n da  instead of –n desu, as demonstrated in the table. The sentences are written first in hiragana, which is a phonetic syllabary  (or transliteration) made from simplified  kanji  characters. These sentences are then spelled using Japanese characters. An English translation follows on the right side of the table. Ashita doubutsuen ni ikimasu.明æâ€" ¥Ã¥â€¹â€¢Ã§â€° ©Ã¥Å"’㠁 «Ã¨ ¡Å'㠁 Ã£  ¾Ã£ â„¢Ã£â‚¬â€š(formal) I am going to the zoo tomorrow.(simple statement) Ashita doubutsuen ni iku.明æâ€" ¥Ã¥â€¹â€¢Ã§â€° ©Ã¥Å"’㠁 «Ã¨ ¡Å'㠁 Ã£â‚¬â€š(informal) Ashita doubutsuen ni iku n desu.明æâ€" ¥Ã¥â€¹â€¢Ã§â€° ©Ã¥Å"’㠁 «Ã¨ ¡Å'㠁 Ã£â€šâ€œÃ£  §Ã£ â„¢Ã£â‚¬â€š(formal) I am going to the zoo tomorrow.(explaining his or her plans for tomorrow.) Ashita doubutsuen ni iku n da.明æâ€" ¥Ã¥â€¹â€¢Ã§â€° ©Ã¥Å"’㠁 «Ã¨ ¡Å'㠁 Ã£â€šâ€œÃ£   Ã£â‚¬â€š(informal) Note how in Japanese, social context is very important. In English, the social situation, or position of the person you are addressing, would make little or no difference. You would tell a good friend at school or a visiting dignitary at a formal state dinner that you are going to the zoo using the same words. Yet, in a formal situation in Japan, you would use –n desu, but you would use  Ã¢â‚¬â€œn da if the circumstance were less formal. In the case of the first two sentences above, you would use –masu  in a formal situation but omit the ending altogether if the setting or circumstances were informal. Why Questions In Japanese, why questions are often completed with –n desu because they are asking for a reason or an explanation, as the table demonstrates: Doushite byouin ni iku n desu ka.Haha ga byouki nan desu.㠁 ©Ã£ â€ Ã£ â€"㠁 ¦Ã§â€"…é™ ¢Ã£  «Ã£  Ã£â€šâ€œÃ£  §Ã£ â„¢Ã£ â€¹Ã£â‚¬â€šÃ¦ ¯ Ã£ Å'çâ€"…æ °â€"㠁 ªÃ£â€šâ€œÃ£  §Ã£ â„¢Ã£â‚¬â€š Why are you going to the hospital?Because my mother is sick. Doushite tabenai n desu ka.Onaka ga suiteinai n desu.㠁 ©Ã£ â€ Ã£ â€"㠁 ¦Ã© £Å¸Ã£  ¹Ã£  ªÃ£ â€žÃ£â€šâ€œÃ£  §Ã£ â„¢Ã£ â€¹Ã£â‚¬â€šÃ£ Å Ã£  ªÃ£ â€¹Ã£ Å'㠁™ã â€žÃ£  ¦Ã£  ªÃ£ â€žÃ£â€šâ€œÃ£  §Ã£ â„¢Ã£â‚¬â€š Why don't you eat?Because I am not hungry.

Needle stick injuries Research Paper Example | Topics and Well Written Essays - 3000 words

Needle stick injuries - Research Paper Example These injuries pose a risk for development of various infectious diseases to the injured threatening their employment, health morbidity and mortality. More than 20 different pathogens have been identified to be transmitted through exposure to body fluids or sharps injury. Injuries by sharps and splashes of body fluids are the main routes of transmission for occupational acquisition of blood-borne pathogens among health care workers (Bi et al, 2008). Despite these injuries being common, they are often under reported and in many places, both health care and non-health care workers are unaware of safety methods to prevent these infections. Globally, needle stick injuries are the most common cause of blood-borne infections among health care workers (Wilburn and Eijekamans, 2004). More than 35 million people worldwide constitute health care work force and they represent 12 percent of the working population in the world (Wilburn and Eijekamans, 2004). It is estimated that people working wi th them as non-health workers are even more in numbers (NHS, 2008). ... In this essay, various concerns pertaining to needle stick injuries will be discussed along with current and best practices and strategies to change. Needle stick injuries: causes, risks and concerns According to the Health Protection Agency report (2008), the most common type of exposure that has been reported among health care workers is the percutaneous injury which accounts for 45 percent of exposures. These exposures contributed to significant seroconversion for HCV, HIV and other diseases. The HIV seroconversion rates reported were high, 0.8 percent. In the NHS, needle stick injury continues to be the most commonly reported adverse incident among healthcare workers, which are a potential source for transmission of various diseases like Hepatitis B and C and human immunodeficiency virus. These injuries are also a potential source of transmission of prion-related diseases. The risk of transmission of hepatitis C with needle stick injuries is 3 percent, for hepatitis B is 30 perce nt and for HIV is 0.3 percent (Elmiyeh et al, 2004). The transmission from the patient to the healthcare worker through the injury depends on the viral load of the patient and also on the amount of blood that passes from the patient to the healthcare worker. Other infections which are transmissible through needle stick injuries are malaria, syphilis and herpes (Wilburn and Eijekamans, 2004). Needle stick injuries: current practices There is uncertain information about the prevalence of the diseases among hospital population and health care workers and non-health workers (Elmiyeh et al, 2004). According to a study by Elmiyeh et al (2004), 38 percent of health care workers had atleast one needle

The death penalty Research Paper Example | Topics and Well Written Essays - 1000 words

The death penalty - Research Paper Example Retribution and deterrence are often cited as the major objectives aiming to achieve by giving death penalty in America; however, these objectives are difficult to achieve under present circumstances. America is often accused for showing double standards while deciding capital punishments for the Whites and Blacks. It is a fact that some hard core criminals may repeat the crimes if they released from the prison. Some people argue that capital punishment will force people to think in terms of the value associated with human life. However, capital punishment will eliminate the differences between a civilized and uncivilized society. The secrets behind life and death are unknown to science and technology yet. In short, death penalty is a complex topic and is difficult to either support or criticize it. The Death Penalty â€Å"The death penalty is the ultimate, irreversible denial of human rights† (Death Penalty). Death penalty is one of the highly controversial subjects in the wo rld because of the serious ethical issues involved in it. Critiques of death penalty argue that humans don’t have the moral or legal right to take the life of another person even if he has committed serious crimes. On the other hand, supporters of death penalty argue that in order to save the lives of innocent people or to save the people from threats, death penalty is unavoidable at certain circumstances. â€Å"Around 137 countries have abolished the death penalty in law or practice. However, despite international human rights standards, some nations still execute people† (Death Penalty). â€Å"In 2004 four (China, Iran, Vietnam and the US) accounted for 97 percent of all global executions. On average, every 9-10 days a government in the United States executes a prisoner† (Pros and Cons of the Death Penalty (Capital  Punishment)). Surprisingly, United Sates, one of the prominent countries which value and argue for human right protection, has no hesitation in giving death penalties to serious criminals. â€Å"In US, as of April 1, 2008, the Death Penalty was authorized by 37 states, the Federal Government, and the U.S. Military† (The death penalty in the US) (See appendix for more details). This paper analyses the pros and cons of death penalty by taking United States as the example. Capital punishment is an expensive way of punishment compared to other punishments because of the heavy expenses needed for it. It is around 70% more expensive when compared to other punishment methods. The trial of a criminal which leads towards a capital punishment is expensive because of the heavy fees needed to be given to the advocates, expert witnesses, forensic testing etc. â€Å"In the United States, death penalty is said to serve two principal social purposes: retribution and deterrence of capital crimes by prospective offenders† (Delfino & Day, p.1). America is a Christian country which adheres to the teachings of Jesus Christ. But, J esus asked his disciples to love the enemies rather than punishing them. Retribution through capital punishment cannot be justified under any circumstances if we analyze it though the lenses of Christian doctrines. Deterrence is the second objective of giving capital punishments to criminals. However, hard core criminal activities are growing across the world and united Sates is also not an exception.

Theories of Motivation Essay -- Management Employee Motivation

Theories of Motivation According to Greenberg (1999) motivation is defined "as a process of arousing, directing and maintaining behaviour towards a goal." Where ‘directing' refers to the selection of a particular behaviour; and ‘maintenance' refers to the inclination to behave with consistency in that manner until the desired outcome is met. Motivation is therefore the force that transforms and uplifts people to be productive and perform in their jobs. Maximising an employee's motivation is necessary and vital to successfully accomplish the organisation's objectives and targets. However this is a considerable challenge to any organisation's managers, due to the complexity of motivation and the fact that there is no ready made solution or an answer to what motivates people to work well (Mullins, 2002). It is my intention in this essay to explore some issues around motivation and cite work based experiences to illustrate and substantiate any arguments or points of view. Main Body Mullins (2002) classifies motivation into Intrinsic and Extrinsic types. Intrinsic motivation involves psychological rewards to enhance job satisfaction, such as the opportunity to use one's ability, a sense of achievement, receiving appreciation and positive recognition or being treated in a considerate manner (Mullins, 2002:P490). Such methods ensure employees are constantly motivated while being engaged in activities that are enjoyable and rewarding. I was formerly employed by a supplier of automobile parts where in addition to using compensation as a means of motivation; they too were dedicated in ensuring their employees had maximum job satisfaction. This was achieved by giving autonomy in their job functions and assigning significa... ...its employees. In today's complex business environment; traditional approaches like monetary incentives are not the only prime motivators. In addition to expecting financial incentives for their performance, employee's expectations are much more. Appreciation, recognition and opportunities for personal growth; must be catered for to harness maximum productivity. Furthermore in an era where change is imperative for the organisation's survival, highly motivated employees, represent flexibility and show willing to change; a vital component for the success of any organisation.

Postmodernism And The Future Of Literature - 1214 Words

Postmodernism and the Future of Literature During the 19th and early 20th, Western world experienced numerous historical events and influential changes, including the Word Wars and technological revolutions. These phenomenons affected the society at large, including in the aspect of art and literature. Literary historians often classified literature from late 19th century until the end of World War II as modernism and literature after World War II as postmodernism. Although there are no explicit definitions, common traits can often be found that distinguished these two categories. In this paper, I will be examining modernism and postmodernism literature, as well as whether postmodernism still continue until now, focusing on Italo Calvino’s†¦show more content†¦Postmodernism artists enjoyed experimenting on literary techniques, such as metanarrative and lack of character developments, which received mixed response in literature world. One of the most notable works in postmodernism era is Calvino’s If On A Winter’s Night A Traveler. Just like many postmodern works, If On A Winter’s Night A Traveler is a metafiction, using second person narrative form to further emphasis its self-consciousness. Calvino indicated his intention by starting his book with the sentence â€Å"You are about to begin reading Italo Calvino’s If On A Winter’s Night Traveler† (1), addressing the main character of the book as â€Å"You† or â€Å"the Reader†. In addition, the book is high fragmented, another trait commonly found in postmodernism works. The book is divided into 22 parts, each in the form of double chapters, alternating between numbered chapters telling story of the character â€Å"You†, and unnumbered chapters containing the first chapter of 10 separate stories. With the concept of beginning a whole new story on each unnumbered chapters, Calvino was able to explore a wide range of genres, spanning from mystery to romance, in a single book. The discontinuity of the chapters result in absence of clear image of characters in each stories.
