The Most Useful (or Important) Scientific Invention Essay Example for Free

The Most Useful (or Important) Scientific Invention Essay The microscope is considered one of the most useful and important scientific inventions known to man. The microscope was invented by Anton van Leeuwenhoek during the seventeenth century. Leeuwenhoek was not a scientist by profession. Initally he made a living selling clothes and buttons, but spent his spare time grinding lenses and constructing microscopes of remarkable quality, such as the light microscope. The light microscope could magnify cells, for instance in plants so you could see a clearer and bigger picture of what they are made of. Over the years, scientists improved on Anton van Leeuwenhoeks microscope by creating microscopes with higher magnifications and far better resolutions, so specimens examined had a sharper image. The latest improvement was the electron microscope, which uses electron beams instead of lamps or mirrors reflecting light like the light microscope. As a result, microscopes have made science today, appear to have more substance, inviting the interest of many young and even old minds. Microscopes also provide the opportunity to identify unknown objects, judging from the various characteristics they may have, so they can be grouped or classed along with others. For instance, microscopes can differentiate between two cells, due to the presence or absence of contents they are supposed to contain. The electron microscope is usually used in such cases as it can magnify the internal structures of a cell where as the light microscope would just give an idea of how the structures are spaced in the cell and not necessarily their characteristics. As simple as this may seem, this differentiation can lead to the diagnosis of a disease that a person may have. This is the main reason why microscopes are so important and useful not only in medical research, but in survival of life as well. The identification of many viruses, fungi, plants, animals and bacteria are owed to the invention of the microscope. Without the microscope, people would not be aware of diseases they may have, which could be life-long, fatal, or contagious, resulting in many deaths and illnesses around the world as there is no way diseases can be cured without being identified. Therefore, the invention of the microscope has proven itself to be very useful from the day of its invention to today, leaving room for even more improvement for years to come.

Dentist Admissions Essay: Changing the World One Gum at a Time :: College Admissions Essays

Changing the World One Gum at a Time My college plans include attending a two-year college and then pursing a degree in dental hygiene. I believe that I will have a great opportunity to give back to my community with my chosen career. As a dental hygienist, there would be many ways to help young and old alike. The time that I would volunteer would enable me to become more involved in the life of our community. Our community usually has a small health fair sponsored by our local hospital. Services are offered to the public free of charge or for small fees. The health fair has not included dental health services. I think that this would be a wonderful way to promote good dental health. Brochures for all ages could be provided on the importance of dental hygiene. This would also be an excellent time to encourage and teach young children the importance of brushing their teeth. Toothbrushes and toothpaste could be provided for the children at this time. Another opportunity in giving back to the community would be through the school system. With the financial help of local civic clubs, kits could be prepared for the students in the elementary school. Through the kits, the children could be taught the importance of taking care of their teeth. I believe that the younger students would respond well to the "tooth fairy." The tooth fairy could then teach the correct techniques for brushing and flossing teeth. This would be a fun experience for the younger students, as well as a fun reminder. Here again, students would be educated and provided a service. One other way that I believe I could give back to my community would be through the local nursing home. Comfort and not being forgotten are both important to our senior citizens. Checking with the nursing staff on the condition of the residents' dentures would be an opportunity to serve. The nursing staff could recommend those residents that might have minor problems with dentures.

F -14 Tomcat :: essays research papers

F-14 TOMCAT Wing span: 64 feet unswept; 38 feet swept Length: 62 feet 7 inches Height: 16 feet Weight: Empty: 40,104 pounds Maximum take-off: 74,348 pounds Speed: Maximum: 1,544 mph Cruise: 576 mph Ceiling: More than 56,000 feet Power plant: Two Pratt and Whitney TF-30-P412A turbofan engines with afterburners; F-14B and F-14D: F-110-GE-400 augmented turbofan engines with afterburner Crew: two Contractor: Grumman Aerospace F-14 Tomcat, sleek, powerful, deadly, and the real star of the movie Top Gun. The F-14 Tomcat followed a history of "Cats" in the military. The F-4F Wildcat and the F-6F Hellcat that fought in the skies years before the Tomcat ever bit the air. In the late 1960's, the U.S Navy decided to decided to focus on an aircraft dedicated to fleet defense. Grumman had already begun developing the F-14, and was definitely headed for a "Cat" designation. The person responsible for this project was Admiral Tom Conolly, Deputy Chief, Naval Operations for Air. The aircraft was dubbed "Tom's Cat" long before the official name of "Tomcat" was ever adopted. (novia.net, 1999) Overall, the Navy's Grumman F-14 Tomcat is without equal among today's Free World fighters. Six long-range AIM-54A Phoenix missiles can be guided against six separate threat aircraft at long range by the F-14's AWG-9 weapons control system. For medium-range combat, Sparrow missiles are carried; Sidewinders and a 20mm are available for dogfighting. In the latter role, the Tomcat's variable-sweep wings give the F-14 a combat maneuvering capability that could not have been achieved with a "standard" fixed planform wing. (history.navy, 1999) In full forward-sweep position,the wings provided the lift needed for slow-speed flight, especially needed during carrier landings. In swept-back positions, the wings blend into the aircraft, giving the F-14 Tomcat a dart-like silhouette for high-speed, super-sonic flight (using Pratt & Whitney TF30-P-412A Turbofans). (novia.net. 1999) By 1972, the first of the F-14 Tomcat's off the production line were sent to the US . In October of 1972, two squadrons were formed with the F-14 Tomcat to begin flight operations. (novia.net, 1999) All in all, fourteen aircraft were used for the development program. The fully proven F-14 was introduced to the fleet only 51 month after contract award! (Anft, 1998) The F-14 Tomcat was designed to carry a million dollar missile, the Phoenix . The AIM-54 Phoenix has a range of over 100 miles and sole purpose was to destroy Soviet bombers. The F-14 Tomcat program came down to a test at the Naval Missile Test Center at Point Mugu, CA in November, 1973. The Pentagon wanted an aircraft that could take on six different targets at once, and on that day in November, the Tomcat

Virtual Merchants

A Virtual merchant is any website which offers the sale of goods or services in a return for remuneration. [ (Tatum, 2010) ] Virtual merchants are essentially the same as a retail outlet, except they only operate online, example Amazon. They allow the consumer easy and instant access to view/purchase merchandise at the click of a button anytime and anywhere. Online stores are now being called e-tailers as they are highly popular with the general consumer. For example in 2008 Amazon had over ‘’76 million active customers accounts and order fulfilment to more than 200 countries’’. [ (DaveChaffey, last modified 13-03-2008) ] Amazons success and domination in the market place is well known. Customers tend to stay loyal to the e-tailer as they are extremely reliable on delivery, have an easy and user friendly online interface and are constantly learning and establishing trading relationships with its customer’s example possible likes e-mails. This loyalty aspect is one problem which most virtual merchants face and in Amazons case the customer orientated strategy they employ seems to be very effective at maintaining brand loyalty. ‘’Relentlessly focus on customer experience by offering our customers low prices, convenience, and a wide selection of merchandise’’ [ (DaveChaffey, last modified 13-03-2008) ] Many trading merchants offer the virtual trading aspect to their existing physical business to stay competitive and diverse within in the market place. This retail outlet coupled with the virtual merchant allows the business to appeal to a larger target market of potential customers, example the convenience shopper (online) and the physical shopper. This type of merchant can be referred to as bricks and clicks merchant example Wal-Mart. The value proposition defines how a company’s product or service fulfils the needs of customers (Kambil, Ginsberg and Bloch 1998). In Amazons case the value proposition is quiet simple as it aims to offer the world’s biggest choice of certain goods and be extremely customer focused and orientated. Amazon offers a personalised and customized service at a very competitive cost to their customers at the click of a mouse. According to Kambil 1997 and Bakos 1998, offering personalization, customization of product offerings and a reduction on product search costs are extremely important factors in developing a company’s value proposition. A company’s revenue model defines how they intend to generate profit and return on investment. In the virtual merchant market place there are several ways where profit can be generated. Firstly there is the direct sales profit margin and in amazons case they don’t have to rent retail outlets in busy high streets etc only merchandise warehousing storage etc, this accompanied with its online trading medium means that overheads, example direct contact with customer and reduction in sales support costs, are kept to a minimum allowing Amazon to offer an unrivalled selection and value for money. This places Amazon extremely competitive within the market place. Secondly they offer other businesses space to advertise on their webpage for example Hewlett pacard, Thompson holidays, Travel lodge etc. Virtual merchants are constantly looking to be dynamic and diverse in their service which they provide and different ways in targeting new customers. The e-tailer market is constantly growing as new users and accounts are set up every day. Amazon began in 1995 and have gained there competitive advantage within their market, they generated over 5 billion in sales in under a decade. When we compare this statistic with Wal-Mart (a bricks and clicks merchant) it took them twenty years to hit this sales figure. This is an indicator of how big and expanding the e-tailer market is.

Current situation about the issues of animal experimentation from different views Essays

Current situation about the issues of animal experimentation from different views Essays Current situation about the issues of animal experimentation from different views Paper Current situation about the issues of animal experimentation from different views Paper Abstraction This aim of this research paper is chiefly to better understand the current state of affairs about the issues of carnal experimentation from different positions. Online articles, diaries, encyclopaedia and books were used for mention in this research paper. In kernel, this research paper by and large touches on the pros and cons of carnal experimentation. Supporters of carnal proving claim that this helps the development of of import drugs and interventions which in bend saves 1000000s of valuable human lives. Additionally, carnal testing is employed to salvage human lives because human lives are more valuable than carnal lives. Valuable cognition can be obtained through carnal experimentation to analyze the effects of a substance. This work will lend to people who are interested to cognize more about animate being testing and future research of similar subject. Animal Testing 1.0 Introduction The Greeks believed that animate beings were a lesser signifier of life because animate beings could non believe like worlds did. Furthermore, this idea was continued by Christians who claimed that animate beings were less important because they had no psyche ( Vivisection, 2002 ) . Animal testing is the usage of unrecorded animate beings for research in order to better understand the consequence of certain substances towards human wellness. This application has been widely carried out in many industries. Numerous animate beings have been used for carnal testing, such as guinea hogs, coneies, Canis familiariss and mice. The issue of carnal testing has become a world-wide focal point these yearss due to statements brought up by those who are against carnal experimentation. Unquestionably, the pattern of carnal experimentation has increased enormously compared to the yesteryear. Harmonizing to Shandilya ( 2008 ) , it is estimated that 20 million animate beings are used for carnal experimentation annually for the intent of medical specialty and for proving other merchandises. Findingss from surveies indicate that less than 10 per centum of pure psychological researches use animate beings as trial topics, which do non include carnal topics used for cross-over medical experimentation ( American Psychological Association, n.d. , cited in Harding, L. , 2001 ) . However, there are some who province that animate being experiments are barbarous and immoral, besides go againsting an animate being s rights. This has caused many persons to hold with the motions of anti-vivisection administrations due to barbarous intervention towards animate beings. Although there are Torahs sing carnal proving implementing the decrease in the usage of animate beings for vivisection, oppositions of animate being experimenting are still debating about the topic of legalising it. If we view this topic from a broader position, it can be seen that carnal testing should be legalized as it aids scientist in the finds of new drugs and interventions to do wellness and medical specialty better, human life is more cherished than that of an animate being, and it is the most precise manner to happen out the effects of substances on a life being. This research paper will explicate why carnal testing should be legalized. Research findings are confined to the United States of America, since the topic of animate being testing is extremely debated there and the advancement of this issue in the US is comparative to other states. 2.0 Body of Report 2.1 Animal proving helps in the development of drugs and interventions. Presently, worlds are frequently exposed to assorted diseases which are life threatening, which includes bing diseases or new signifiers of diseases due to mutants and alterations in the environment. Hence, research workers are working hard in happening remedies for all these unwellnesss. From here, it can be seen that carnal testing is indispensable in the nutriment of human wellness. Animals will be used to analyze the consequence of freshly invented drugs, whether it will assist in bring arounding the disease. Speaking of the positive results of carnal testing, this includes the development of new medical specialty and interventions. Derbyshire ( 2004 ) mentioned that many medical progresss utilized carnal testing ; including production of insulin which was developed utilizing Canis familiariss, and cyclosporine, a powerful anti-rejection drug developed utilizing Primatess. Besides this, finds of assorted vaccinums have evolved through carnal experimentation. From here, it can be seen that carnal proving can steer us to finds of new cognition about life beings. Many drugs have been invented to carry through the purpose of rectifying diseases. However, the side effects of freshly invented drugs remain unknown. Therefore, carnal testing allows the rating of the danger of drugs before being used upon worlds which will greatly cut down the hazard before any human based tests are carried out ( About Animal Testing, n.d. ) . Drugs that are tested safe can so be used to salvage 1000000s of valuable human lives. The hereafter of medical scientific discipline still relies on animate being testing, and this clearly shows a demand in legalising carnal testing. There are some people who claim that the effects of drugs tested on animate beings may non be the same to worlds. Arthritis drug Vioxx, which caused 140 000 bosom onslaughts and shots in United States of America, was withdrawn from the planetary market even though it appeared to be safe when tested in animate beings ( Archibald, 2004 ) . However, scientists have proven that animate beings are highly alike to worlds and experiments done on them would bring forth similar consequences obtained through future human experiments ( About Animal Testing, n.d. ) . Hence, transporting out carnal proving on drugs would better the quality of human life indirectly. Therefore, to sum it all up, carnal testing should be legalized because it assists research workers in medical interventions besides drugs find, improves wellness and medical specialty and is able to prove the safety of drugs. Options of carnal proving are non every bit plausible as they are non every bit accurate as the consequences obtained from trials conducted upon animate beings. Hence, carnal testing should be encouraged alternatively of being suppressed. 2.2 The importance of human lives is given precedence over carnal lives. Differences bing between worlds and animate beings cause animate beings to have interventions which are different and unequal although both of them are alive. As animate beings differ from worlds as they do non hold scruples, they are considered inferior to worlds when it comes to the value of life. Sing that the lives of worlds are viewed as more valuable than carnal lives, animate beings will hold to be sacrificed in carnal experimentation. The pros and cons of carnal proving were debated with both sides being able to bring forth solid grounds for their bases. From the position of sense, it is mentioned that all living things are morally tantamount. However, the lives of worlds are superior over the lives of animate beings ( Garner, 2005 ) . Governments have to do a pick between the public assistance of worlds and the public assistance of animate beings. Which one is more of import, the life of a human or the life of an animate being? As Archibald ( 2004 ) points out, most people are willing to give the lives of animate being in carnal proving to salvage human lives. Even though human public assistance is the chief concern, the public assistance of an animate being is still taken into history by minimising the agony of animate beings when carry oning carnal experimentations. The Animal Welfare Act had been formed and reviewed invariably to protect animate beings and diminish the figure of vivisections carried out ( Monamy, 2000 ) . Every experiment affecting the use of animate beings is usually administered with anaesthesia. In concurrence with this, the experiments will non be repeated or animate beings used will be euthanized when barbarous intervention is involved. Animal testing can be accepted as it allows the betterment of human life quality without the agony of animate beings ( Garner, 2005 ) . Those who are against carnal proving argued that animate beings have the right to populate peacefully. Animal testing is regarded as unkind intervention towards animate beings as it violates carnal rights as their lives are valuable as good ( Le Fanu, 2003 ) . However, their statements are weak because animate beings lack the sense of judgement, and hence are non subjected to moral claims and carnal rights ( Cohen, 1986 ) . Hence, they can non be compared with human life. Equally long as the animate being is experimented upon without hurting, the public assistance of the animate being is non violated. Therefore, it is acceptable to legalise the activity of carnal proving as human life should be prioritized. Although there are many who are against carnal experimentation, the points asserted are non strong plenty to stop the activity of animate being proving. Supporters of carnal proving affirm that animate beings should non hold equal rights with worlds as both of these can non be compared. Animals lack the sense of judgement, therefore human lives ever come foremost before carnal lives. Animals are considered to be protected every bit long as animate beings receive minimal sum of agony. So carnal testing should be legalized in order to salvage more human lives. 2.3 Animal testing is helpful for analyzing the effects of substances. Many new chemical substances are produced every twelvemonth to run into the demand of the planetary market such as in agribusiness, medical specialty and decorative merchandises. The credits should be given to animal proving. The consequence of that peculiar substance has been studied to bring forth infinite helpful merchandises. This can increase the length of service of worlds besides bettering the human criterion of life. By carry oning experiments on animate beings, the research worker can derive priceless information from the populating specimen. Winston ( 2006 ) mentioned that 70 % of the Nobel awards for physiology or medical specialty are contributed from carnal proving. Hence, it is clearly shown that by executing researches on animate beings by analyzing the effects of a substance can convey a immense impact upon the universe. The find of cognition will be delayed or remain undiscovered if carnal testing is non carried out. As stated by Le Fanu ( 2003 ) , primates offer the best experimental theoretical accounts as they have 99 % similarity in cistrons with worlds. Animal testing can be carried out on Primatess to guarantee the safety of some drugs before being tested on worlds. The opportunity for both beings exhibiting the same consequence is high due to the similarity of their cistrons. This in bend can cut down the hazards faced by worlds when get downing the tests. Hence, animate beings are good tools for larning the effects of assorted substances. In malice of this, people who are in resistance to animal proving argue that it must non be legalized merely because carnal experimentation leads to medical discoveries and the result is more rewarding. This statement is deficient to warrant the drawbacks of carnal testing ( Derbyshire, 2004 ) . On the other manus, it is proven that the good result outweighs its drawbacks, so it is rational to legalise the activity of animate being testing. Without analyzing the effects of substances utilizing carnal testing, most of the major vaccinums against disease like infantile paralysis, German measles and hepatitis B used today would non be ( Derbyshire, 2004 ) . New drugs undergo in vitro research, computing machine mold and carnal testing before being tested on worlds. Therefore, every measure is critical in this procedure of analyzing the effects before a drug is introduced into the market. In short, the effects of a substance can be study by transporting out carnal proving which can supply priceless information besides the anatomy of some animate beings are similar to worlds. Even though carnal experimentation its disadvantages, there are still many benefits that can derive by transporting out carnal proving. Therefore, legalisation of carnal testing must be accepted. Furthermore, it can be a good tool for instruction and research intents. 3.0 Recommendation Normally, the use of animate beings for carnal proving delineated as inhuman treatment towards animate beings and should non be legalized. However, it is impossible to censor the pattern of carnal experimentation due to the benefits brought by animate being research towards world. Animal testing is a baronial action to prolong the public assistance of worlds. Since the pattern of carnal proving can non be stopped, the public assistance of animate beings can merely be protected by another attack. The rule of Three Rs , that is refinement , decrease and replacing can be practiced. The research workers are pledged to cut down the figure of animate beings used when executing a research. To utilize the least figure of resources to obtain the fastest consequences, research workers have the inclination of utilizing a smaller figure of animate beings during their research. This is an act that showed the willingness of world to cut down the inhuman treatment towards the animate beings. Besides this, scientists were asked to decrease the grade of agony of the animate being. This can be attained by exclude some gratuitous harmful actions affecting the animate beings. Last, alternate methods should be used whenever possible to replace the use of carnal testing ( Derbyshire, 2006 ) . For case, the public assistance of animate beings can be secured by making so. The pattern of carnal experimentation should compromise between the public assistance of worlds and animate beings so that harmoniousness can be achieved. Animal experimentation still can be practiced, and the Torahs should be purely enforced so that it is non violated by irresponsible people. 4.0 Decision Due to the increased use of carnal testing, the issue of carnal experimentation is acquiring extremely debated and remains relentless. After analyzing several points, it has revealed that carnal testing should be legalized as it helps in the advancement of medical specialty and wellness, human life is more valuable than carnal life, and helps to larn the result of a substance on a life being. Day by twenty-four hours, anti-vivisectionists try to govern out carnal testing by looking at this issue from the animate being s point of position. Concurrently, protagonists of carnal experimentation were able to rebut their statements, by claiming the public assistance of worlds should ever come first before animate beings. They viewed the topic of carnal proving from a broader position and the long term advantages that come from carnal experimentation. Life is neer perfect, some forfeits have to do to accomplish success for a better hereafter. However, carnal research should be carried out a s its advantages are more important than the disadvantages.

Presently, worlds are frequently exposed to assorted diseases which are life threatening, which includes bing diseases or new signifiers of diseases due to mutants and alterations in the environment. Hence, research workers are working hard in happening remedies for all these unwellnesss. From here, it can be seen that carnal testing is indispensable in the nutriment of human wellness. Animals will be used to analyze the consequence of freshly invented drugs, whether it will assist in bring arounding the disease. Speaking of the positive results of carnal testing, this includes the development of new medical specialty and interventions. Derbyshire ( 2004 ) mentioned that many medical progresss utilized carnal testing ; including production of insulin which was developed utilizing Canis familiariss, and cyclosporine, a powerful anti-rejection drug developed utilizing Primatess. Besides this, finds of assorted vaccinums have evolved through carnal experimentation. From here, it can be seen that carnal proving can steer us to finds of new cognition about life beings. Many drugs have been invented to carry through the purpose of rectifying diseases. However, the side effects of freshly invented drugs remain unknown. Therefore, carnal testing allows the rating of the danger of drugs before being used upon worlds which will greatly cut down the hazard before any human based tests are carried out ( About Animal Testing, n.d. ) . Drugs that are tested safe can so be used to salvage 1000000s of valuable human lives. The hereafter of medical scientific discipline still relies on animate being testing, and this clearly shows a demand in legalising carnal testing. There are some people who claim that the effects of drugs tested on animate beings may non be the same to worlds. Arthritis drug Vioxx, which caused 140 000 bosom onslaughts and shots in United States of America, was withdrawn from the planetary market even though it appeared to be safe when tested in animate beings ( Archibald, 2004 ) . However, scientists have proven that animate beings are highly alike to worlds and experiments done on them would bring forth similar consequences obtained through future human experiments ( About Animal Testing, n.d. ) . Hence, transporting out carnal proving on drugs would better the quality of human life indirectly. Therefore, to sum it all up, carnal testing should be legalized because it assists research workers in medical interventions besides drugs find, improves wellness and medical specialty and is able to prove the safety of drugs. Options of carnal proving are non every bit plausible as they are non every bit accurate as the consequences obtained from trials conducted upon animate beings. Hence, carnal testing should be encouraged alternatively of being suppressed. 2.2 The importance of human lives is given precedence over carnal lives. Differences bing between worlds and animate beings cause animate beings to have interventions which are different and unequal although both of them are alive. As animate beings differ from worlds as they do non hold scruples, they are considered inferior to worlds when it comes to the value of life. Sing that the lives of worlds are viewed as more valuable than carnal lives, animate beings will hold to be sacrificed in carnal experimentation. The pros and cons of carnal proving were debated with both sides being able to bring forth solid grounds for their bases. From the position of sense, it is mentioned that all living things are morally tantamount. However, the lives of worlds are superior over the lives of animate beings ( Garner, 2005 ) . Governments have to do a pick between the public assistance of worlds and the public assistance of animate beings. Which one is more of import, the life of a human or the life of an animate being? As Archibald ( 2004 ) points out, most people are willing to give the lives of animate being in carnal proving to salvage human lives. Even though human public assistance is the chief concern, the public assistance of an animate being is still taken into history by minimising the agony of animate beings when carry oning carnal experimentations. The Animal Welfare Act had been formed and reviewed invariably to protect animate beings and diminish the figure of vivisections carried out ( Monamy, 2000 ) . Every experiment affecting the use of animate beings is usually administered with anaesthesia. In concurrence with this, the experiments will non be repeated or animate beings used will be euthanized when barbarous intervention is involved. Animal testing can be accepted as it allows the betterment of human life quality without the agony of animate beings ( Garner, 2005 ) . Those who are against carnal proving argued that animate beings have the right to populate peacefully. Animal testing is regarded as unkind intervention towards animate beings as it violates carnal rights as their lives are valuable as good ( Le Fanu, 2003 ) . However, their statements are weak because animate beings lack the sense of judgement, and hence are non subjected to moral claims and carnal rights ( Cohen, 1986 ) . Hence, they can non be compared with human life. Equally long as the animate being is experimented upon without hurting, the public assistance of the animate being is non violated. Therefore, it is acceptable to legalise the activity of carnal proving as human life should be prioritized. Although there are many who are against carnal experimentation, the points asserted are non strong plenty to stop the activity of animate being proving. Supporters of carnal proving affirm that animate beings should non hold equal rights with worlds as both of these can non be compared. Animals lack the sense of judgement, therefore human lives ever come foremost before carnal lives. Animals are considered to be protected every bit long as animate beings receive minimal sum of agony. So carnal testing should be legalized in order to salvage more human lives. 2.3 Animal testing is helpful for analyzing the effects of substances. Many new chemical substances are produced every twelvemonth to run into the demand of the planetary market such as in agribusiness, medical specialty and decorative merchandises. The credits should be given to animal proving. The consequence of that peculiar substance has been studied to bring forth infinite helpful merchandises. This can increase the length of service of worlds besides bettering the human criterion of life. By carry oning experiments on animate beings, the research worker can derive priceless information from the populating specimen. Winston ( 2006 ) mentioned that 70 % of the Nobel awards for physiology or medical specialty are contributed from carnal proving. Hence, it is clearly shown that by executing researches on animate beings by analyzing the effects of a substance can convey a immense impact upon the universe. The find of cognition will be delayed or remain undiscovered if carnal testing is non carried out. As stated by Le Fanu ( 2003 ) , primates offer the best experimental theoretical accounts as they have 99 % similarity in cistrons with worlds. Animal testing can be carried out on Primatess to guarantee the safety of some drugs before being tested on worlds. The opportunity for both beings exhibiting the same consequence is high due to the similarity of their cistrons. This in bend can cut down the hazards faced by worlds when get downing the tests. Hence, animate beings are good tools for larning the effects of assorted substances. In malice of this, people who are in resistance to animal proving argue that it must non be legalized merely because carnal experimentation leads to medical discoveries and the result is more rewarding. This statement is deficient to warrant the drawbacks of carnal testing ( Derbyshire, 2004 ) . On the other manus, it is proven that the good result outweighs its drawbacks, so it is rational to legalise the activity of animate being testing. Without analyzing the effects of substances utilizing carnal testing, most of the major vaccinums against disease like infantile paralysis, German measles and hepatitis B used today would non be ( Derbyshire, 2004 ) . New drugs undergo in vitro research, computing machine mold and carnal testing before being tested on worlds. Therefore, every measure is critical in this procedure of analyzing the effects before a drug is introduced into the market. In short, the effects of a substance can be study by transporting out carnal proving which can supply priceless information besides the anatomy of some animate beings are similar to worlds. Even though carnal experimentation its disadvantages, there are still many benefits that can derive by transporting out carnal proving. Therefore, legalisation of carnal testing must be accepted. Furthermore, it can be a good tool for instruction and research intents. 3.0 Recommendation Normally, the use of animate beings for carnal proving delineated as inhuman treatment towards animate beings and should non be legalized. However, it is impossible to censor the pattern of carnal experimentation due to the benefits brought by animate being research towards world. Animal testing is a baronial action to prolong the public assistance of worlds. Since the pattern of carnal proving can non be stopped, the public assistance of animate beings can merely be protected by another attack. The rule of Three Rs , that is refinement , decrease and replacing can be practiced. The research workers are pledged to cut down the figure of animate beings used when executing a research. To utilize the least figure of resources to obtain the fastest consequences, research workers have the inclination of utilizing a smaller figure of animate beings during their research. This is an act that showed the willingness of world to cut down the inhuman treatment towards the animate beings. Besides this, scientists were asked to decrease the grade of agony of the animate being. This can be attained by exclude some gratuitous harmful actions affecting the animate beings. Last, alternate methods should be used whenever possible to replace the use of carnal testing ( Derbyshire, 2006 ) . For case, the public assistance of animate beings can be secured by making so. The pattern of carnal experimentation should compromise between the public assistance of worlds and animate beings so that harmoniousness can be achieved. Animal experimentation still can be practiced, and the Torahs should be purely enforced so that it is non violated by irresponsible people. 4.0 Decision Due to the increased use of carnal testing, the issue of carnal experimentation is acquiring extremely debated and remains relentless. After analyzing several points, it has revealed that carnal testing should be legalized as it helps in the advancement of medical specialty and wellness, human life is more valuable than carnal life, and helps to larn the result of a substance on a life being. Day by twenty-four hours, anti-vivisectionists try to govern out carnal testing by looking at this issue from the animate being s point of position. Concurrently, protagonists of carnal experimentation were able to rebut their statements, by claiming the public assistance of worlds should ever come first before animate beings. They viewed the topic of carnal proving from a broader position and the long term advantages that come from carnal experimentation. Life is neer perfect, some forfeits have to do to accomplish success for a better hereafter. However, carnal research should be carried out a s its advantages are more important than the disadvantages.

Communications in the movies essays

Communications in the movies essays Communication in the Movies: Rainman Everyday, everywhere we go, in everything we do, we see, hear, and use communication. The movies is no exception. In watching the movie Rainman I observed many different types of communication both effective and ineffective. The main character of the movie, Charlie, begins the movie as a very stubborn and selfish man who does not use particularly good communication skills when talking to others: he often does not make a good climate which leads to negative spirals, he does not use empathy, and he easily becomes defensive. In the course of the movie he meets his brother, Ray, who suffers from autism which makes it difficult for him to communicate with others. The obstacle of Rays difficulty in communication at first frustrates Charlie, but he soon learns that there is nothing he can do but learn to communicate in a way that Charlie will be able to understand. In the movie Rainman, Charlie starts off using a very selfish, ineffective communication style, but learns to participate, observe, and adapt to the situation and becomes a much better communicator. The movie begins with Charlie Babbitt (played by Tom Cruise) who receives a phone call saying that his estranged father has passed away. He goes with his girlfriend, Susanna, to the funeral and is shocked to find out that his father only left him some rosebushes and an old car while someone else received all of his fathers fortune. That someone else turns out to be Ray Babbitt (played by Dustin Hoffman), the brother Charlie never knew he had. Ray lives in a mental hospital due to his severe autism and has no concept for the money he has inherited. Charlie decides to take matters into his own hands and kidnap Ray in hopes of getting the money. The two brothers end up driving across the country together and on the way Charlie learns of Rays amazing ability to count and remember numbers. Charlie decides to take Ray to Las Vega...

I stand Against Capital Punish essays

I stand Against Capital Punish essays Capital punishment is what I consider, the legal punishment of a criminal. Capital punishment has been used as a form of punishment for many years. At modern time, capital punishment is more controlled. Although, when capital punishment is mentioned it brings shivers down the back of most of society. Being it is a factor of death, capital punishment The term capital does not represent or signify any ideas in the negative aspect. Capital is defined as first or foremost; first rate or excellent. Punishment, on the other hand, is defined as the rough handling or penalization for a wrong doing. Neither of these terms, when mentioned individually signify anything in the negative aspect. Although when these two terms are combined there is alot more meaning to them than just excellent or penalization. These now strictly signify, death. Capital punishment has been a form of disciplining since 1750 B.C., when it was part of the code of Hammarabi. The bible itself, also prescribes death as a penalty for any of thirty crimes committed. The crimes ranged from any between murder and fornication. In the 18th century more than two hundred capital crimes were recognized, and as a result over one thousand people a year were faced with the sentence of Now at modern time, the death penalty, has been rekindled. Although, it is not as barbaric as it was. Now the law only allows itself the use certain types of disciplining. In the early 18th and 19th century the death penalty was inflicted in many ways. Some ways were, crucifixion, boiling in oil, drawing and quartering, impalement, beheading, burning alive, crushing, tearing asunder, stoning and drowning. In the late 19th century the types of punishments were limited and only a few of them remained permissible by law. In the 19th century capital punishment ...

Questions and Answers - Assignment Example The misuse of hard liquor is itself a social harm, with additional economic costs as well as increased health consequences in the long-term (Mathurin & Deltenre, 2009). For parents sending their teenagers off to college, the survey results are but a sobering reminder that not all activities in college are caged in slide rules and long hours at the library. Noteworthy, such negative publicity informs public opinion, whether true or falls, on the type of policies operationalized in such institutions. The study deviates a little from the survey rankings and so seeks to determine whether there is any relationship/connection between a student’s gender and binge drinking in such institutions of higher learning. To get the answers sought after, the study will sample opinions of students on whether such negative partying has any relationship with one’s gender. The study will utilize a sample size of 100 students, with each selected using simple random sampling

Politics of globalization 2 Essay Example | Topics and Well Written Essays - 1000 words

Politics of globalization 2 - Essay Example It experiences internal rebellion and external sanctions and aggression as it attempts to achieve economic and political independence within a global political economy. Taken separately, each of the many hurdles to Iran's economic recovery would be somewhat daunting; taken together; they are formidable (Mohammadi, 2003). As stated earlier, the effects of globalization on Iran are many- both positive and negative. Some of them are discussed below. Globalization has had a mammoth effect on the Military sector of Iran which we call the diffusion of power. In terms of the concentration of power, the direction of events seems to be firmly away from any globalizing trend and toward the diffusion of power and regionalization of interaction. (Buzan.B, Wver.O, & Wilde.J, 1998) Liberalization, as the name implies, generally means the relaxation of certain rigid restrictions and regulations. Sometimes, liberalization is associated with privatization; however, both are two different processes. In the Iranian context, market liberalization includes the agricultural front- rice and wheat markets and so on. This is another effect of globalization on Iran There are several definitions for democratization and in one of the best definitions Korany states that it "entails an expansion of political participation in such a way as to provide citizens with a degree of real and meaningful collective control over policy."Democratization in Iran is one of the main effects of globalization. The development of democratization in Iran is rife with impediments and these impediments are challenged by certain social trends within Iranian society. After a careful examination of democratization, the impediments, forces and methods thereof, we have learned that there is no one simple answer in developing democracy in Iran. Thus, these are the three major effects of globalization on Iran. (Democratization in Iran, n.d) Role of domestic politics in Iran's globalization policy. US foreign policy toward Iran has evolved to a point that it can no longer compete with or overcome certain forces. At the same time, forces are present that could assist the US in reestablishing formal dialogue and, ultimately, normal diplomatic relations with Iran. Globalization is the force that in some instances is assisting US foreign policy. At the same time, other elements of globalization are eroding US desires with respect to Iranian programs in WMD. The time has come for the US to admit that its current policy of sanctions is obsolete. The US needs to reengage Iran on economic and social terms that are the byproducts of economic globalization. (George.S, 2003). Politics of identity- Iran's globalization policy As Iran follows the theoracracy (a political unit governed by a deity or by officials thought to be divinely guided) all the policies and theories are. The challenges that Iran faces in regard to globalization are evident enough, first it is economics and second is politics.. The diverse on post-revolutionary development are reflected in the debates within Iran on globalization: reformers allude to Iran's strength in this field,

Assignment - Essay Example There is an established communication between Adam (man) and God (divine). Adam is seen stretching his hand reluctantly and loosely to receive what God is presenting to him. God is trying to transmit some sought of divinity to man. This is being attempted by bringing their fingers as close as possible but it is clear the fingers do not establish a contact. This could be the impossibility of God and man being into contact. The story is biblical though and it has it that after Creation of Adam, God breathed life into him. In the bible there is nowhere we are told that there was a lot of resistance in the process. However, in the creation of man, the work presents an interesting fact (Kleetus, 2005). God is seen trying to reach Adam with all his might. He is stretching his index finger to touch that of Adam. It seems there is a resistance in form of a wind, which is trying to deny him a chance to communicate to his creation. The presence of a wind-like force is depicted in the direction of God’s legs and those of the angels surrounding him. The implication from the figure here is that God is trying with all his might to touch and transmit his mightiness to hid creation amidst a strong opposing force. On the other hand, dam does not seem to have the energy and effort to reach to God. Adam is relaxed and while God is using his right hand to reach him, Adam is using his right hand to support his lazily leaning body and reluctantly uses his left hand to respond to God’s attempt to reach him. The left hand has to be supported by his left leg knee for that case. Adam’s body is leaning against God and it seems he is not willing enough or putting enough effort to make the divine connection with God. The body language of the two is totally different and while one is responding with strength to establish a connection, the receiver is not so much putting an effort to receive. A closer look at the index fingers of the two subjects in

Are Technologically Advanced Societies More Advanced Essay

Are Technologically Advanced Societies More Advanced - Essay Example This is to say that such word is susceptible to varying interpretations. In such case, it is contended that the advancement of a community should not be measured by the number of technologies that it has. Rather, it should be determined by considering the whole aspects of society. It is not to be limited to the advantages that new technology has brought to the people. Stated otherwise, the definition of advancement should not be superficial but substantial. A substantial definition is one which involves the consideration of the people’s state of life. This is to say that, as of this moment, the determination of what constitutes progress should involve economic factors. A country’s economy actually reflects its growth and development. Also, in today’s world, the definition of the word progress is often associated to economic terms due to globalization. Advancement and progress are two interchangeable terms. Both of them signify the growth and development of a soci ety. In such case, either of the two words could actually be used to explain the topic of the essay. It is a contention that there is progress if the following factors are present: (1) all the members of the society are experiencing a high standard of living (2) there is full employment and (3) there is good governance. The three factors are actually essential in determining â€Å"progress.†

Life for African Americans in the United States after slavery was Essay

Life for African Americans in the United States after slavery was abolished - Essay Example After the defeat of the Confederacy, the southern states faced economic and physical devastation. While millions of slaves got freedom legally, the political infrastructures of the southern states lost their legitimacy. Transformation of the South into a free labor economy and readmission of the southern states to the union imparted the need for reconstruction of the South. Freedom fight of the slaves in the post-Civil War and the Reconstruction Era transformed into a struggle for survival. Most of the slaves that had been withdrawn from the plantations were penniless. African Americans’ wages frequently fluctuated as a result of their perceived worth. Manual labor could be replaced easily in the post-Civil War era. There were only a few ex-slaves that had the kind of money to own a piece of land as a vast majority of the ex-slaves dealt with the issue of lack of source of income. As per the estimate of the 1880 Census, no more than 20 per cent of the African Americans were, i n part, the owners of the land on which they farmed (â€Å"Being an African American†). Most of such holdings were also beset with debt that led to the crippling of the ex-slaves in the long run. For some, life at the time of slavery was better than after its abolishment because as slaves, they at least had some place to sleep and eat at that time. Sharing his views on the dark side of emancipation in the post-Civil War era, Johnson stated, â€Å"Since them times, a many a nigger has had it tough to make a livin’. I know dat is so, too, cause I has been all long dere† (Johnson). Ex-slaves saw immense poverty during the Reconstruction Era. Years of prevalence of poverty caused a lack of medical care and nourishment among the ex-slaves which resulted in a high rate of mortality among the African Americans in general and among their children in particular. Ex-slaves were under the burden of due medical bills and were still not able to access the required medical at tention. Many started using herbal remedies to treat their illnesses. According to the Census of 1900, annual death rate of the African Americans was 30 in every 1,000 opposed to no more than 17 per 1,000 among the White Americans (â€Å"Being an African American†). 79 years old James Johnson, an ex-slave from Columbia noted that he â€Å"[felt] and [knew] dat de years after de war was worser than befo’† (Johnson). Although the slaves’ freedom was secured by The Emancipation Proclamation and victory of The Union, yet ex-slaves were not liberated under the Jim Crow Laws and segregation. Emancipation brought along with it new kinds of challenges, insecurities, and problems for the ex-slaves. Malnourishment and health deterioration were only some of the multitude of problems ex-slaves had to deal with in the post-Civil War era. A deep sense of isolation from their families weakened the ex-slaves emotionally and psychologically. This division was mainly cause d by the sale of slaves, owners’ death, and presentation of the slaves in the pre-Civil War era as gifts from one owner to another. The slaves’ newly found freedom was dampened by loneliness and alienation. White Americans not only saw the African Americans as a nuisance upon normality but also as a potential risk to their dominance. â€Å"Our greatest danger is that in the great leap from slavery to freedom we may overlook the fact that the masses of us are to live by the productions of our hands, and fail to keep in mind that we shall prosper in proportion as we learn to dignify and

BUS599 - Integrative Project, Mod 5 SLP Essay Example | Topics and Well Written Essays - 1250 words

BUS599 - Integrative Project, Mod 5 SLP - Essay Example The pricing for the other products X6 and X7 have to undergo strategic analysis and appropriate changes in order to retain and improve the company based on the remaining two products. The New Year celebration comes at the beginning of the year 2016, but we realize that the celebration experience was not valuable because the year 2015 did not end with better performance. This calls for an analysis of the performance of the last two years so as to determine the major causes of low performance and make better decisions for the future. As we compare the results for the last two Time Warps, we allocate appropriate decisions that will improve the performance for 2016. We then take the results through the analysis of Cost, Volume and Profit to determine the differences in results obtained. Simulation We begin simulation by analyzing each product separately. Based on the decision to discontinue product X5 in the year 2015, we will first have an analysis of the products X6 and X7, then a sepa rate analysis for product X5 in order to know whether to remain as discontinues or return to the market. We will have the simulation results as follows: Product X6 The X6 has existed for the last 5 years, and was discontinued for 2016 as a result of having attained market saturation point. ... Its pricing depends on parameters for high performance and cost effectiveness. It has not reached its saturation point in the market hence it is not discontinued. It proceeds to the year 2016. Year 2014 2015 2016 Price 275 250 246 Results and Decisions The simulations indicate that product X5 and X6 do not make it to the year 2016. Both of them reach saturation points and they no longer attract customers. Product X7 continues in the market in 2016 and the first time customers continue to increase. The results can be interpreted to mean that as long as there is a product whose customers depend on a single attribute, it will certainly attain a saturation point of the price and looses the power to retain customers. At the same time it fails to attract new customers as in the case of product X5 and X6. It leads the management of Clipboard Tablet Company to consider producing more of product X7 than the others. Difference in Results using CVP Analysis (Cost, Volume and Profit) The analysi s of cost, volume and profits enables a company to develop and focus on the approaches that will introduced in connection to the product pricing (Williams & Williams, 2010). It also focuses on the needs of research programs that can improve the productivity and customer satisfaction index of a company. Clipboard Tablet Company can now formulate and implement the strategies that on the basis of Cost, Volume and Profit analysis (CVP). CVP analysis will enable Clipboard Tablet Company to determine the best strategy to use in connection to the pricing of the three products. It also determines when a particular product should be discontinued depending on the contemporary ranges of tablets prices in the market (Drury, 2007). A CVP analysis is an

A modest proposal Essay Example for Free

A modest proposal Essay Swift also incorporates the use of gruesome details delivered in a pleasant voice, an example of this is, the skin of which, Artificially dressed, will make admirable Gloves for Ladies. This challenges the readers beliefs between right and wrong, and makes him think of how horrible and cruel they are to the Catholics. It does this because the idea of making anything with parts of a human is horrible, and to make something associated with the rich, Gloves for Ladies makes it even more horrible that they dont want to relate to the narrator, who is someone like them. We also see this when he says, particularly Weddings and Christenings. Here, the narrator suggests eating babies at Christenings, which is sickening and goes against any human feelings. He uses this to makes the reader aware that this problem is getting out of hand, and makes the reader realise that is something should be done soon or the problem will escalate to something as sickening as eating babies. This technique desensitises and spoils the readers expectations, and the fact that they are shocked makes them question the fact that they have associated with the narrator in the first place. Another technique Swift uses is entirely unacceptable suggestions made as if acceptable. An example of this is, A Child well Nursed is at a year Old a most delicious, nourishing and wholesome Food. This unexpected exaggeration of detail stuns the reader and makes him think how sick and twisted the narrator is. He then realises that the narrator is Protestant, and how Swift is mocking them and therefore becomes aware of how badly the Catholics are being treated. Another example of this is when he says, I rather recommend buying the Children alive, and dressing them hot from the Knife, as we do roasting. This technique changes the perceptions of the reader because it gives them a twisted image of something that would normally sound appetizing (when roasting a meat), and who up to this point has identified with the narrator, and encourages the reader to think of alternatives to solve the problem, that are moral and justified. Swift also includes some truth, to show how the Catholics are living and being treated. An example of this is when he says, they are every Day dying, and rotting, by cold, and famine, and filth, and vermin. This use of truth creates feelings for the Catholics and makes the reader understand their position. These subtle digs at the affluent Protestants tell the reader they are to blame, this is shown when he says, for Landlords, who as they have already devoured most of the Parents. This shows the mistreatment of the Catholics because they make them seem like murderers, something a high-class person would hate, and makes the reader realise of this and object to the idea. A Modest Proposal has been written with two levels of meaning. The first is that Swift adopts a persuading false act, which is shown through the narrator, but reveals true anger and disgust at the indifferent attitude of landowners the rich and religious Protestants and the intolerance of his time. Swifts use of satirical techniques shows us what was happening at his time through a very different approach. He uses this approach to surprise and mock the readers, which is much more effective, because it makes the readers realise by comparing their ideas to horrible ones that they are in the wrong. This also makes the reader listen and realise better than just a pamphlet saying how bad the Protestants are.

Data Multimedia Images

Data Multimedia Images Chapter I Introduction 1.1 What is meant by Multimedia Data? A number of data types can be characterized as multimedia data types. These data types are normally the essentials for the building blocks of core multimedia environments, platforms and integrating tools. The basic types can be described as text, images, audio, video and graphic objects. Following is a detailed explanation for the same. Text Text can be stored in a variety of different forms. In addition to American Standard Code for Information Interchange (ASCII) based files, text is usually stored in spreadsheets, annotations, processor files, databases and common multimedia objects. The task of text storage is becoming more and more complex due to the easy availability and abundance of Graphical User Interfaces (GUIs) and text fonts, permitting unique effects such as text color, text shade etc. Images Digitalized images are nothing but a string of pixels that signify an area in the user’s graphical exhibit. There is an immense variation in the quality and dimension of storage for motionless images. For motionless (still) images, the space overhead varies with respect to complexity, size, resolution and compression format used to store any given image. The frequently used and accepted image formats (file extensions) consist of bmp, jpeg, tiff and png. Audio Audio, being another frequently used data type is relatively space intensive. A minute of sound takes up to 3 Megabytes (MB) of space. Numerous methods can be deployed to compress an audio into suitable formats. Video Another data type which consumes majority of space is categorized as the digitalized video data type. Videos are normally stored as a series of frames, the capacity of which depends on its resolution. A solo video frame can take up to 1 MB of space. Continuous transfer rate is needed to get a reasonable video playback with its proper transmission, compression, and decompression. Graphic Objects This data type consists of unique data structures that can define 2D and 3D shapes which further helps in defining multimedia objects. Today one can use different formats for image applications and video-editing applications. To list few examples Computer Aided Design (CAD) and Computer Aided Manufacturing (CAM) are graphic objects 1.2 How is Multimedia Data Different? Theoretically multimedia data should be considered like any regular data based on the data types for instance numbers, dates and characters. Though, there are a few challenges that arise from multimedia as described in [2]: Multimedia data is usually captured with various unreliable capturing techniques such as image processing. These multimedia processing techniques require capabilities for handling these various available methods of capturing content, this includes both automated and manual methods. In multimedia database, the queries created by the user rarely come back with textual answer. To a certain extent, the answer to user query is a compound multimedia presentation that the user can glance through at one’s leisure. The size of the multimedia data being large not only affects the storage, retrieval but also the transmission of data. Time to retrieve information may be vital while accessing video and audio databases, for example Video on Demand. Automatic feature extraction and Indexing: User explicitly submits the attribute values of objects inserted into the database in contrast to advanced tools with conservative databases, such as image processing and pattern recognition tools for images to extract the various features and content of multimedia objects. Special data structures for storage and indexing are needed due to the large size of data. 1.3 Basic Approaches for Data Retrieval Data management is being implemented since long. Many approaches have also been invented for the same to manage and inquire various types of data in the computer systems. The commonly used approaches for data management comprise of conventional database system, information retrieval system, content based retrieval system and graph/ tree pattern matching. The details for the same are as follows: Conventional database system It is the most extensively used approach to manage as well as investigate structured data. Data in a database system must match to some predefined structures and limitations (schema’s). The user should specify the data objects to be retrieved and the tables from which data has to be extracted. The user also has to predicate on which the retrieval of data will be based to formulate a database query. SQL, a query language has a restricted syntax and vocabulary that can be used for such databases. Information retrieval (IR) system This system is prominently used to search enormous text collections; where in the content of the data (text) is illustrated with the help of an indexer using keywords or a textual summary. The query demands are expressed in terms of keywords or natural language. For instance, searching for an image or video, the user is required to describe using words and also need means to store large amount of metadata in textual form. Content based retrieval (CBR) system This approach facilitates in the retrieval of multimedia objects from an enormous collection. The retrieval is based on various features such as color, texture and shape which can be extracted automatically from the objects. Though keyword can be considered a feature for textual data, conventional retrieval of information has a higher performance as compared to content-based retrieval. This is due to the fact that keyword has the demonstrated ability to characterize semantics while no other features have revealed convincing semantic describing capability. A key disadvantage of this particular approach is its lack of accuracy. Graph or tree pattern matching This particular approach seeks the retrieval of object sub-graphs from an object graph as per several designated patterns. Chapter II Data Structures for Multimedia Storage Many modern database applications deal with large amounts of multidimensional data. Multimedia content-based retrieval is one of the examples. Access Methods are essential in order to deal with multidimensional data efficiently. They are used to access selective data from a big collection. 2.1 Importance of Access Methods Efficient spatial selection support is the key purpose of access methods. These include range queries or nearest neighbour queries of spatial objects. The significance of these access methods and how they take into account both clustering techniques and spatial indexing is described by Peter Van Oosterom [3]. In the absence of a spatial index, every object in the database needs to be checked if it meets the selection criteria. Clustering is required to group the objects that are often requested together. Or else, many different disk pages will have to be fetched, resulting in a very slow response. For spatial selection, clustering implies storing objects that are not only close in reality but also close in computer memory instead of being scattered all over the whole memory. In conventional database systems sorting the data is the basis for efficient searching. Higher dimensional data cannot be sorted in an obvious manner, as it is possible for text strings, numbers, or dates. Principally, computer memory is one-dimensional. However, spatial data is 2D, 3D or even higher and must be organized someway in the memory. An intuitive solution to organize the data is using a regular grid just as on a paper map. Each grid cell has a unique name e.g. ’A1’, ’C2’, or ’E5’. The cells are stored in some order in the memory and can each contain a fixed number of object references. In a grid cell, a reference is stored to an object whenever the object overlaps the cell. However, this will not be very efficient due to the irregular data distribution of spatial data because of which many cells will be empty while many others will be overfull. Therefore, more advanced techniques have been developed. 2.2 kd Trees A kd-tree or a k-dimensional tree is a space-partitioning data structure used for organizing points in a k-dimensional space. kd-trees are a useful for several applications such as searches involving a multidimensional search key like range searches and nearest neighbour searches. Kd-trees are a special case of Binary Space Partitioning (BSP) trees. A kd-tree only uses splitting planes that are perpendicular to one of the coordinate axes. This is different from BSP trees, in which arbitrary splitting planes can be used. In addition to this, every node of a kd-tree, from the root to the leaves, stores a point. Whereas in BSP trees, leaves are typically the only nodes that contain points. As a consequence, each splitting plane must go through one of the points in the kd-tree. [4] 2.2.1 Addition of elements to kd trees A new point is added to a kd tree in the same way as one adds an element to any other tree. At first, traverse the tree, starting from the root and moving to either the left or the right child depending on whether the point to be inserted is on the left or right side of the splitting plane. Once you get to a leaf node, add the new point as either the left or right child of the leaf node, again depending on which side of the node’s splitting plane contains the new point. 2.2.2 Deleting from kd trees Deletion is similar as in Binary Search Tree (BST) but slightly harder. Step1 find node to be deleted. Step2 two cases must be handled: (a) No children replace pointer to node by NULL (b) Has children replace node by minimum node in right subtree. If no right subtree exists then first move left subtree to become right subtree. [1] 2.3 Quad-trees Each node of a quad-tree is associated with a rectangular region of space. The top node is associated with the entire target space. Each non-leaf node divides its region into four equal sized quadrants, likewise, each such node has four child nodes corresponding to the four quadrants and so on. Leaf nodes have between zero and some fixed maximum number of points. 2.3.1 Simple definition of node structure of a point quad-tree qtnodetype = record INFO: infotype; XVAL: real; YVAL: real; NW, SW, NE, SE: *qtnodetype end Here, INFO is some additional information regarding that point . XVAL, YVAL are coordinates of that point. NW, SW, NE, SE are pointers to regions obtained by dividing given region. [1] 2.3.2 Common uses of Quad-trees Image Representation Spatial Indexing Efficient collision detection in two dimensions Storing sparse data, such as formatting information for a spreadsheet or for some matrix calculations. 2.3.3 Representing Image Using Quad-tree: [7] Let us suppose we divide the picture area into 4 sections. Those 4 sections are then further divided into 4 subsections. We continue this process, repeatedly dividing a square region by 4. We must impose a limit to the levels of division otherwise we could go on dividing the picture forever. Generally, this limit is imposed due to storage considerations or to limit processing time or due to the resolution of the output device. A pixel is the smallest subsection of the quad tree. To summarize, a square or quadrant in the picture is either : entirely one color composed of 4 smaller sub-squares To represent a picture using a quad tree, each leaf must represent a uniform area of the picture. If the picture is black and white, we only need one bit to represent the colour in each leaf; for example, 0 could mean black and 1 could mean white. Now consider the following image : The definition of a picture is a two dimensional array, where the elements of the array are colored points. Figure 2.3: First three levels of quad-tree Figure 2.4: Given Image This is how the above image could be stored in quad-tree. Figure 2.5: 88 pixel picture represented in a quad-tree Figure 2.6: The quad tree of the above example picture. The quadrants are shown in counterclockwise order from the top-right quadrant. The root is the top node. (The 2nd and 3rd quadrants are not shown.) 2.3.4 Advantages of Quad-trees: They can be manipulated and accessed much quicker than other models. Erasing an image takes only one step. All that is required is to set the root node to neutral. Zooming to a particular quadrant in the tree is also a one step operation. To reduce the complexity of the image, it suffices to remove the final level of nodes. Accessing particular regions of the image is a very fast operation. This is useful for updating certain regions of an image, perhaps for an environment with multiple windows. The main disadvantage is that it takes up a lot of space. 2.4 R-trees R-trees are N-dimensional extension of Binary trees, but are used for spatial access methods i.e., for indexing multi-dimensional information. They are supported in many modern database systems, along with variants like R+ -trees and R*-trees. The data structure splits space with hierarchically nested, and possibly overlapping, minimum bounding rectangles.[4] A rectangular bounding box is associated with each tree node. [5]   Bounding box of a leaf node is a minimum sized rectangle that contains all  the rectangles/polygons associated with the leaf node. Bounding box associated with a non-leaf node contains the bounding box associated with all its children. Bounding box of a node serves as its key in its parent node (if any) Bounding boxes of children of a node are allowed to overlap. 2.4.1 Structure of an R-tree node rtnodetype = record Rec1, .Reck : rectangle P1, .Pk : âˆâ€"rtnodetype end A polygon is stored in one node, and the bounding box of the node must contain the polygon. Since a polygon is stored only once, the storage efficiency of R-trees is better than that of k-d trees or quad-trees. The insertion and deletion algorithms use the bounding boxes from the nodes to ensure that close by elements are placed in the same leaf node. Each entry within a leaf node stores two-pieces of information; a way of identifying the actual data element and the bounding box of the data element. 2.4.2 Inserting a node 1. Find a leaf to store it, and add it to the leaf. To find leaf, follow a child (if any) whose bounding box contains bounding box of data item, else child whose overlap with data item bounding box is maximum 2. Handle overflows by splits. We may need to divide entries of an overfull node into two sets such that the bounding boxes have minimum total area. 2.4.3 Deleting a node 1. Find the leaf and delete object; determine new MBR. 2. If the node is too empty: Delete the node recursively at its parent Insert all entries of the deleted node into the R-tree 2.4.4 Searching R-trees Similarly, for searching algorithms, bounding boxes are used to decide whether or not to search inside a child node. Here we need to find minimal bounding rectangle. In this way, most of the nodes in the tree are never touched during a search. If the node is a leaf node, output the data items whose keys intersect the given query point/region Else, for each child of the current node whose bounding box overlaps the query point/region, recursively search the child. 2.5 Comparison of Different Data Structures [1] k-d trees are very easy to implement. However, in general a k-d tree consisting k nodes may have a height k causing complexity of both insertion and search in k-d trees to be high. In practice, path lengths (root to leaf) in k-d trees tend to be longer than those in point quad-trees because these trees are binary. R-trees have a large number of rectangles potentially stored in each node. They are appropriate for disk access by reducing the height of the tree, thus leading to fewer disk access. The disadvantage of R-trees is that the bounding rectangle associated with different nodes may overlap. Thus when searching an R-tree, instead of following one path (as in case of quad-tree), we might follow multiple path down the tree. This difference grows even more acute when range search and neighbour searches are considered. In case of point quad-trees, while performing search/insertion each case requires comparisons on two coordinates. Deletion in point quad-trees is difficult because finding a candidate replacement node for the node being deleted is not easy. Chapter III Metadata Metadata is data about data. Any data that is used to describe the content, condition, quality and other aspects of data for humans or machines to locate, access and understand the data is known as Metadata. Metadata helps the users to get an overview of the data. 3.1 Need of Metadata The main functions of metadata can be listed as follows: [8] Description To describe and identify data sources. These descriptions help create catalogs, index, etc., thereby improving access to them. Querying Formulation of queries. Administration To provide information to help manage and administrate a data source, such as when and how it was created, and who can legally access it. Preservation To facilitate data archival and preservation like data refreshing and migration, etc. Technical To indicate how a system functions or metadata behaves, such as data formats, compression ratios, scaling routines, encryption key, and security, etc. Use To indicate the level and type of use of data sources like multiversion, user tracking, etc. 3.2 Metadata in the Life Cycle of Multimedia Objects A multimedia object undergoes a life cycle consisting of production, organization, searching, utilization, preservation, and disposition. Metadata passes through similar stages as an integral part of these multimedia objects [8]: Creation Objects of different media types are created often generating data of how they were produced (e.g., the EXIF files produced by digital cameras) and stored in an information retrieval system. Associated metadata is generated accordingly for administrating and describing the objects. Organization Multimedia objects may be composed of several components. Metadata is created to specify how these compound objects are put together. Searching and retrieval Created and stored multimedia objects are subject to search and retrieval by users. Metadata provides aids through catalog and index to enable efficient query formulation and resource localization. Utilization Retrieved multimedia objects can be further utilized, reproduced, and modified. Metadata related to digital rights management and version control, etc. may be created. Preservation and disposition Multimedia objects may undergo modification, refreshing, and migration to ensure their availability. Objects that are out-of-date or corrupted may be discarded. Such preservation and disposition activities can be documented by the associated metadata. 3.3 Classification of Metadata Metadata directly affects the way in which objects of different media types are used. Classifying metadata can facilitate the handling of different media types in a multimedia information retrieval system. Based on its (in)dependence on media contents, metadata can be classified into two kinds, namely content independent and content-dependent metadata [8]: Content-independent metadata provides information which is derived independently from the content of the original data. Examples of content independent metadata are date of creation and location of a text document, type-of-camera used to record a video fragment, and so on. These metadata are called descriptive data. Content-dependent metadata depends on the content of the original data. A special case of content-dependent metadata is content-dependent descriptive metadata , which cannot be extracted automatically from the content but is created manually: annotation is a well-known example. In contrast, content-dependent non-descriptive metadata is based directly on the contents of data. 3.4 Image metadata Some of the image files containing metadata include Exchangeable image file format (EXIF) and Tagged Image File Format (TIFF). Having metadata about images embedded in TIFF or EXIF files is one way of acquiring additional data about an image. Image metadata are attained through tags. Tagging pictures with subjects, related emotions, and other descriptive phrases helps Internet users find pictures easily rather than having to search through entire image collections. A prime example of an image tagging service is Flickr, where users upload images and then describe the contents. Other patrons of the site can then search for those tags. Flickr uses a folksonomy: a free-text keyword system in which the community defines the vocabulary through use rather than through a controlled vocabulary. Digital photography is increasingly making use of metadata tags. Photographers shooting Camera RAW file formats can use applications such as Adobe Bridge or Apple Computers Aperture to work with camera metadata for post-processing. Users can also tag photos for organization purposes using Adobes Extensible Metadata Platform (XMP) language, for example. [4] 3.5 Document metadata Most programs that create documents, including Microsoft PowerPoint, Microsoft Word and other Microsoft Office products, save metadata with the document files. These metadata can contain the name of the person who created the file, the name of the person who last edited the file, how many times the file has been printed, and even how many revisions have been made on the file. Other saved material, such as document comments are also referred to as metadata. Document Metadata is particularly important in legal environments where litigation can request this sensitive information which can include many elements of private detrimental data. This data has been linked to multiple lawsuits that have got corporations into legal complications. [4] 3.6 Digital library metadata There are three variants of metadata that are commonly used to describe objects in a digital library: descriptive Information describing the intellectual content of the object, such as cataloguing records, finding aids or similar schemes. It is typically used for bibliographic purposes and for search and retrieval. structural Information that ties each object to others to make up logical units e.g., information that relates individual images of pages from a book to the others that make up the book. administrative Information used to manage the object or control access to it. This may include information on how it was scanned, its storage format, copyright and licensing information, and information necessary for the long-term preservation of the digital objects. [4] Chapter IV Text Databases Basic text comprises of alphanumeric characters. Optical character recognition (OCR) practices are deployed to translate analog text to digital text. The most common digital representation of characters is the ASCII code. For this, seven bits are required (eight bits might be used, where in the eighth bit is reserved for a special purpose) for each character. Storage space for a text document that is required is equivalent to the number of characters. For instance, a 15 page text document consisting of about 4000 characters generally consumes 60 kilobytes. Now days, structured text documents have become extremely popular. They comprise titles, chapters, sections, paragraphs, and so forth. A title can be presented to the user in a different format than a paragraph or a sentence. Different standards are used to encode structured information such as HTML and XML (hyper text markup language and extensible markup language) There are different approaches like Huffman and Arithmetic Coding, which can be used for text compression, but as the storage requirements are not too high, these approaches are not as important for text as they are for multimedia data. [10] 4.1 Text Documents A text document consists of identification and is considered to be a list of words. Likewise, a book is considered to be a document, and so is a paper in the events of a conference or a Web page. The key identification used for a book may be an ISBN number or the title of the paper together with the ISBN number of the conference event or a URL for a Web page. Retrieval of text documents does not normally entail the presentation of the entire document, as it consumes a large amount of space as well as time. Instead, the system presents the identifications of the chosen documents mainly along with a brief description and/or rankings of the document. 4.2 Indexing Indexing refers to the derivation of metadata from their documents and storage in an index. In a way, the index describes the content of the documents. The content can be described by terms like social or political for text documents. Also, the system utilizes the index to determine the output during retrieval. The index can be filled up in two ways, manually as well as automatically. Assigned terms can be added to documents as a kind of annotation by professional users such as librarians. These terms can be selected often from a prescribed set of terms, the catalog. A catalog describes a certain scientific field and is composed by specialists. One of the main advantages of this technique is that the professional users are aware of the acceptable terms that can be used in query formulation. A major drawback of this technique is the amount of work that has to be performed for the manual indexing process. Document content description can also be facilitated automatically resulting in what are termed as derived terms. One of the many steps required for this can be a step in which words in English text are identified by an algorithm and then put to lower case. Basic tools are used in other steps such as stop word removal and stemming. Stop words are words in the document which have a little meaning and most of the times include words like the and it. These stop words are erased from the document. Words are conflated to their stem in the document through stemming. As an example, the stemmer can conflate the words computer, compute and computation to the stem comput. 4.3 Query Formulation Query formulation refers to the method of representing the information need. The resultant formal representation of information is the query. In a wider perspective, query formulation denotes the comprehensive interactive dialogue between the system and the user, leading to both a suitable query and also a better understanding by the user of the information need. It also denotes the query formulation when there are no previously retrieved documents to direct the search, thus, the formulation of the preliminary query. It is essential to differentiate between the expert searcher and the relaxed end user. The expert searcher is aware of the document collection and the assigned terms. He/ she will use Boolean operators to create the query and will be able to adequately rephrase the same as per the output of the system. In case the result is too small, the expert searcher must expand the query, and in case if the result is too large, he/she must be able to make the query more restrictive. The communication of the need for information to the system in natural language interests the end user. Such a statement of the need for information is termed as a request. Automatic query formulation comprises of receiving the request and generating a preliminary query by the application of algorithms that were also used for the derivation of terms. In general, the query consists of a list of query terms. This list is accepted by the system and it composes a result set. The system can formulate a successive query based on this relevant feedback. 4.4 Matching The matching algorithm is mainly the most important part of an information retrieval system. This algorithm makes a comparison of the query against the document representations in the index. In the exact matching algorithm, a Boolean query, which is formulated by an expert searcher, defines precisely the set of documents that satisfy the query. The system generates a yes or a no decision for each document. In the case of an inexact matching algorithm, the system delivers a ranked list of documents. Users can traverse this document list to search for the information they need. Ranked retrieval puts the documents that are relevant in the top of the ranked list, thus, saving the time the user has to invest on reading those documents. Simple but effective ranking algorithms make use of the frequency allocation of terms over documents. Ranking algorithms that are based on statistical approaches, halve the time the user has to spend on reading those documents. Chapter V Image Databases Digital images can be defined as an electronic snapshot scanned from documents or taken of a scene, for example printed texts, photographs, manuscripts, and various artworks. Digital image is modeled and mapped as a grid of dots, pixels or commonly known picture elements. A tonal value is allocated to each of these pixels, which can be black, white, and shades of gray or color. Pixel itself is symbolized in binary code of zeros and ones. Computer stores these binary digits or bits corresponding to each pixel in a sequence and are later reduced to mathematical representation by compressing them. After compression these bits are interpreted and read to generate an analog output by the computer for display or printing purposes. Figure 5.1: As shown in this bitonal image, each pixel is assigned a tonal value, in this example 0 for black and 1 for white. To further describe the grayscale of a pixel one needs to say that one byte is of eight bits. For a color pixel one needs three colors of one bye each, these colors are red, green and blue. So, for a rectangular screen one can compute the amount of data required for the image using the formula: A = xyb Where A is the number of bytes needed, x is the number of pixels per horizontal line, y is the number of horizontal lines, and b is the number of bytes per pixel. Using this formulae for a screen with value of x being 800, y being 600, and for b being 3; A=xyb thus A = 1.44 Mbyte. Compression is required for this significant amount of data. Image compression is based on exploiting redundancy in images and properties of the human perception. Pixels in specific areas appear to be similar; this concept of similarity is called Spatial Redundancy. Human’s views of images are tolerant r
