Wal-Marts shift to Radio Frequency Identification Essay

Wal-Marts shift to Radio Frequency Identification - Essay Example With money, people could easily purchase exactly what they wanted or needed. This continued on for a few centuries and is still in use in the world though not in the same sense as it used to be before. Today science and technology have revolutionized each and every aspect of human life. Shopping and business are no exceptions-they too have been profoundly modified by technology. Credit cards, billing systems, shopping on the web, internet bank accounts and the system of barcodes on products are some of the examples that depict the extent to which technology has penetrated into this frontier. Even though many advances have been made, global concerns are growing regarding aspects like shoplifting, piracy and misappropriation of products. To check these many solutions have been proposed like the bar code system and most recently the RFID technology. This technology has both merits and demerits as does every other technology ever conceived. Wal Mart's decision to make use of it has given it an impetus. This essay describes about the prospects and aspects of RFID technology keeping Wal Mart in the background. RFID, an emerging technology, stands for Radio Frequency Identification. ...An RFID tag is a small object, such as an adhesive sticker, that can be attached to or incorporated into a product, animal, or person. RFID tags contain antennas to enable them to receive and respond to radio-frequency queries from an RFID transceiver. Passive tags require no internal power source." The tags are generally miniaturized electronic circuits enclosed in protective cases. When they absorb signal from a reading device they get activated and send out data to the reading device. When an RFID tag passes through the electromagnetic zone, it detects the reader's activation signal. The reader decodes the data encoded in the tag's integrated circuit (silicon chip) and the data is passed to the host computer for processing(RFID: From Wikipedia, the free encyclopedia 2005). In this way details like its location etc can be ascertained by the reading device. Based on power consumption tags are classified as active or passive. Passive RFID tags have no internal power supply. They do not contain any batteries inside them. The minute electrical current induced in the antenna by the incoming radio frequency signal provides just enough power for the tag to transmit a response. Lack of an onboard power supply means that the device can be quite small and light weight: commercially available products exist that can be embedded into many products. As of 2005, the smallest such devices commercially available measured 0.4 mm 0.4 mm, which is thinner than a sheet of paper; such devices are practically invisible to the naked eye (RFID: From Wikipedia, the free encyclopedia 2005).

The Importance of Art in Daily Life

The Importance of Art in Daily Life Every day morning, many people enjoy sitting outside watching sunrise. They feel relaxed seeing the arrival of the sun with its pure light and the traveling of the night with its darkness. They consider that a new life will start as the sun starts her new life. Not only they watch the sun, many people enjoy drawing this view because they will feel for once that their minds are relaxed and not thinking except in this new born. This research highlights over the importance of art in our daily life. It also recalls us about the different types of art and how each of them depends on special artist and special instruments used. In this research we will also know the relation between colors and how colors are grouped in two. Also we will notice that art is most important than what we consider because we see art everywhere and each day because every thing in life is an artwork. Art is your emotions flowing in a river of imagination. If you stand for a moment in front any work of art, which has many shapes and many line cannot be described, you start to imagine things by walking on that lines and shapes trying to connect them to get a specific shape done from your imagination. What if the picture is a sunrise? You will begin thinking in every sadness or happiness things that happened to you. No one these days knows the really importance of art. Art is everywhere in the entire world. It is ones creativity and imagination. Art is the most things you use and see always without paying attention to that. If you want to know what does art mean? You have to look at every thing surrounding you, at every thing you use in your daily life, you will notice that every thing you see shows an art, especially your clothes, your hair design, your shoes etc All of them are arts. Art help us see everything and everyone completely different. Art is not a reading to get bored or listening to get epileptic, its something which opens to us a field of questions and answers to things we see. Thats up to us. It doesnt impose itself on us to hear, think, or even understand; on the contrary it takes us to a long-lost world, to a fiction world, to a field of thoughts. Art can be in different forms audio like music, songs, and poems. Visual as film making, photography and painting, they differ depending on artist, style and material used Audio arts are the most used type of art. They can be in the form of music, song or poetries. They help in relaxing ones mind. Music is thought to link all of the emotional and physical elements of the universe. Music can also be used to change persons mood, and has been found to cause like physical responses in many people simultaneously. Music also has the ability to strengthen or weaken emotions from a particular event such as a funeral. (Stancato, 2009) Moreover the song, which is another type of audio art, has physiological effects too. Try for once to know what does successful and motivated people listen to, you will be amazed that they tend to special type of songs and music! You will never find a self-motivated person who does not listen to motivating songs. Although romantic persons listen to special type of songs and music, they listen to classical and romantic ones. Poetries are also a third type of audio art. The author poem expresses his feeling in his writings. They are similar to writing songs, and can be sung too. Both poetries and songs depend on music to be sang, they need an artist having soft voice and the writers mind and pen too. But music doesnt need any of them. Music needs different musical instruments like piano, guitar and others. In addition to different instrument, they come in different times. Visual arts are popular art. They differ from the audio art.à ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒâ€šÃ‚  Artists place images, forms, colors, ideas, down in such a way that can be communicated with you the viewer. When you read the work it will serve your understanding in a multitude of vibrant ways. It will begin to make sense, in some cases a perverse kind of sense. An artist will take you on a trip around his work. He will tell you what to view and in what order. He will attempt to provoke a variety of responses, even negative ones. He will appeal to your sense of wonder. This artwork will and should ask as many questions of both the intellect and the emotions as it answers.à ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒâ€šÃ‚  (simm). This is true of all art. In the visual arts, painting, photography, film making, there is no substitute for looking. The various theories of Emotional Color will, usually all unknown to the viewer, play an increasingly important role. What are these theories? Red for danger, black for death and morbidity, in the western world at least, are two of the most obvious. The Madonnas cowl in a religious painting is always a certain blue. This was originally produced from a semi precious stone called Lapis Lazuli before the advent of chemical paint. The emotional aspects of this should be obvious. Warm colors, reds oranges, yellows appear to come towards the viewer and are on occasion welcoming. The cool colors, blues, some greens appear to recede. Atmospheric or aerial perspective is used by artists in this manner to provoke a feeling of distance or vastness. Have you ever considered why a certain type of music is called the blues? Or why colors themselves are thought to sing? Why certain color combinations are called Complimentary. (These are the opposites on the color wheel, a primary with a secondary, Red and Green, Yellow and Purple, Blue and Orange). (simm)Painting, photography and filmmaking differ in the instrument used and in the way each is viewed. Painting is the a rtisans drawing using his colors, brushes and his wide thought. The artisans drawing depends on his mood and on what type of colors he likes more. Whereas photography is to capture amazing images using a special instrument, the camera or the video too. Film making requires neither colors nor camera. They need a story to be acted. Also it needs the writer and the actor. Hence art is universal, and is everywhere. Not only art is for one who exercise a work art and like it. It is for everyone. Art is more important then one can consider. Without art one cannot see any thing beautiful because art add attraction and beauty to any thing one can look at, even if he look at himself. Also art reflects to us the mood and the feelings of the artist so that if hes happy he will do something amazed or funny, and if he is upset he will use to do things which would hold you to another world of thinks. Some one said Art is the only way to run away without leaving home. This quote is special and is the truth because when you feel upset what is the first thing you resort to? Sure its listening music, playing piano, dancing, drawing etc and others because you will not leave home in a bad mood. All what you will do is a branch of art, because art is the best way to feel that you are relaxed since it helps you to thought deeply about your problems. Also art may help yo u forget everything depressed you because your mind will be as a flying bird, from tree to tree, searching for a place where he will feel safe from the dangers of life. So art is very important because it translates ones feelings and shares his emotions without disturbing him, on the contrary it helps him feel better and forget every thing depressing him. Another example is when a man see a beautiful woman, he will run after her until she accepts to meet him or to give him her number, but if he see an ugly girl, he will change his way because he get disgusted. So art is very important in our life, because without art world will be so disgusted, depressed and bored.

Misconception On Hispanics :: stereotyping

Miss conceptions In today’s society we stereotype the Hispanic race as being lazy and having lot’s of children. People perceive the Hispanic race this way but reality we are all the same. We work hard to get were we are today in society. Many people have bad images of the Hispanic race because they see one Hispanic person who dress a certain way or even acts a certain way and they assume we are all bad people. For example if you see a Hispanic man that is baldheaded and has on baggie clothes people assume that he is a gangster by the way he looks. But what they wouldn’t know is who he really is he could be a straight â€Å"a’† student but only assume he is bad by his appearance. As in Brent Staples essay Black Men and Public Spaces when the man is passing through the park and the women assumes he’s going to hurt her because of the way he looks and how he is acting the woman starts to run away. That is peoples bad miss conception of others beside themselves. Garcia 2 Some Hispanic people try to go their whole life denying who they really are. Like in Passing when Joan Steinau Lester tells us that all of us developed different ways of coping with stereotypes of our groups and of ourselves (260). Most Hispanic people chose to pass because they grew up around hardship and racial slurs from other that thought themselves to be better. Others chose to pass because they seen it done to other Hispanics and did not want to encounter the same reaction. So rather than face who they are and were they come from these people chose to pass and avoid all the negative reactions. Instead of trying to pass Hispanic people should overcome and try to better themselves by getting a good education and get those good jobs. So they wouldn’t have to pass they could be proud of who they are and were their family comes from. So they don’t have to feel like an airborne plant, flourishing without roots (Holman 258). Hispanic people have avoided these harmful situations by passing our by staying far from those who belittle them and not getting into confrontations. Hispanics have not put themselves in an environment where they could be harmed. They surround themselves in all Hispanic communities were they feel comfortable and they don’t have to feel like an outsider in their own community.

Manchild in the Promised Land Essay

The majority of Negroes during the time of Douglass and Washington spent their lives in the fields, gutters, and ghettoes of America. They continue to do so today. Two recently published autobiographies clearly indicate that Negro degradation and deprivation are confined neither to the South nor to earlier times. Claude Brown provides dramatic accounts of life in urban Negro slums. Both are highly readable, although Williamson’s seems less complete and less authentic. Brown tells the story of â€Å"Sonny,† a Harlem â€Å"corner boy† who went to college. His childhood and adolescence included chronic truancy, prolonged friction with his parents, gang fighting and assorted delinquencies. Sonny was intimate with personal danger and suffered severe bodily harm. He was well known to the courts and the youth correctional houses. Although Sonny’s childhood and adolescence appear to have been those of many Harlem youth, he was spared the fate of many of his friends: violent death, permanent body injury, demoralization, and fanaticism. Claude Brown’s account of his experiences growing up in Harlem in the 1950’s indicates it may be equally prevalent in a metropolitan setting. One of Brown’s friends 1965: 425) asserts: The time I did in Woodburn, the times I did on the Rock, that was college man . . . Every time I went there, I learned a little more. When I go to jail now, Sonny, I live, man. I’m right at home. That’s the good part about it . . . Now when I go back to the joint, anywhere I go, I know some people. If I go to any of the jails in New York, or if I do a slam in Jersey even, I still run into a lot of cats I know. It’s almost like a family. (425) For Brown and many of the revolutionaries, the slogan of black power seemed to have this content: †¢ Negroes, by themselves, must assert their political and economic power through such methods as the creation of all-Negro political parties such as the Black Panther Party. Coalition with whites is either impossible or undesirable, for it would undermine Negro dignity. Integration with whites should not be a paramount goal. Rather, Negroes should strengthen their own separate culture and society: â€Å"black is beautiful. † At some future date, if a Negro so chooses, he might integrate with whites. Negroes must affirm their unique identity, learn of their African heritage, and identify with the â€Å"colored† peoples throughout the world. White society is both oppressive and decadent. Negroes should not fight â€Å"the white man’s war† in places such as Vietnam. Violence, at least in self-defense, can and should be used by Negroes to achieve their goals. While Negroes are a minority in America, they can count on the support of Asian and African peoples. American man is now an urban man and he was recently a rural man. It would be strange if the psychological shock of trying to find streets as natural as fields or woods did not provoke savage explosions in the cities. Claude Brown’s brilliant examination of Harlem, Manchild in the Promised Land, showed just how much of the black ghetto’s barbarism came from the sudden transplantation of sharecroppers from shacks to tenements. Robert Kennedy was using more than a politician’s rhetoric when he stated before his murder: ‘We confront an urban wilderness more formidable and resistant and in some ways more frightening than the wilderness faced by the Pilgrims or the pioneers. ‘ Being labeled a troublemaker is a danger of growing up in suburbia as well as in the slums, but the suburbs are more likely to provide parental intervention and psychiatrists, pastors, family counselors to help the youth abandon his undesirable identity. It is much harder for the inner-city youth to find alternatives to a rebel role. Thus it is in the slums that youth gangs are most likely to drift from minor and haphazard into serious, repeated, purposeful delinquency. It is in the slums, too, that young people are most likely to be exposed to the example of the successful career criminal as a person of prestige in the community. To a population denied access to traditional positions of status and achievement, a successful criminal may be a highly visible model of power and affluence and a center of training and recruitment for criminal enterprise. As Ward (1998) describes it: Among the social institutions which delineated black urban associational life, the one most closely related to the vocal group was the street gang. Sometimes the groups and the gangs even shared the same membership. In Baltimore, Johnny Page of the Marylanders doubled as a member of the Dungaree Boys gang, while Julius Williams had dual affiliations as a battling member of the Shakers and as a balladeer with the Royal Jokers in Detroit. â€Å"Julius Williams was the terror of the school†, recalled his classmate Woodie King. â€Å"He was sixteen. He enjoyed fighting teachers and singing in class†. When Claude Brown returned from a juvenile detention centre in upstate New York in the early 1950s, he noticed that many of the old gangs from his Harlem neighbourhood had turned to doowopping in the wake of the Orioles’ inspirational rise from a Baltimore street corner, via an appearance on Arthur Godfrey’s CBS radio show Talent Scouts, to national celebrity (Ward 59) One of the most consistent patterns of emotional concern expressed by the disadvantaged child is for potency or power. His heroes are the strong, invincible men, such as Hercules or Superman. We could speculate that the interest in Greek mythology expressed by disadvantaged pupils is also related to this concern. As a result, we would like to see the schools investigate, with the children, the power concept. This is a possible study topic for even the earliest grades. Can people be strong in ways other than physical strength? The teacher might begin by asking the youngsters who their neighborhood heroes are–who are the â€Å"top cats† on their block–and then asking why they are so. We would guess that the responses will probably be in terms of physical strength. The objective then, would be to help the class begin to explore other routes of power. Staging points for such discussions might be derived from reading excerpts from the powerful autobiography of Claude Brown, Manchild in the Promised Land, the author’s experiences growing up in Harlem. 6 The most direct method, however, to help children feel greater potency is to let them experience it. A way that combines such experience with the improvement of writing skills was demonstrated by one of our teaching interns. In a seventh-grade English class, required by the curriculum guide to study paragraph skills, the teaching intern asked the class, â€Å"How many of you can remember any of the things you had to read in school when you were in the third grade? † Some hands went up, and names of books were reported. â€Å"How did you like them? † Claude Brown’s memories of post-war Harlem churches similarly stressed their extra-religious appeal. He attended one simply because he lusted after the preacher’s daughter and fondly recalled Father Divine’s 155th Street Mission, not for its spiritual nourishment, but because he could get all the food he could eat there for 15 cents. Brown also appreciated that the black churches of Harlem were commercial, as well as religious, enterprises. At Mrs Rogers’ storefront church, he recalled, â€Å"people jumped up and down until they got knocked down by the spirit, and Mrs Rogers put bowls of money on a kitchen table and kept pointing to it and asking for more†.

The Panama and Suez Canals essays

The Panama and Suez Canals essays The Panama and Suez Canals may be two of the biggest achievements in ocean history within the past couple of centuries, but which one was more important globally? The Panama Canal, a waterway that cuts across the Isthmus of Panama and links the Pacific and Atlantic Oceans, is about 51 miles long (The World Book Encyclopedia, Panama Canal). The Suez Canal, a narrow artificial waterway that joins the Mediterranean and Red seas, is about 118 miles long (The World Book Encyclopedia, Suez Canal). Although both canals have obviously impacted our world, the Suez Canal stands out in my mind as the canal that has the bigger impact. The Suez Canal brings in more boats each year than Panama, and it doesn't have locks, water-filled chambers that lift boats from one level of water to another. Another reason why I chose the Suez Canal as the more global one was that the finished canal, which was longer than the Panama Canal, cost about 280 million dollars less. This brings us to our first statemen t. The Suez Canal is about 118 miles long. The Panama Canal is about 51 miles long. Why would the Suez Canal cost less than the Panama Canal? The Suez cost only about 100 million dollars. (The World Book Encyclopedia, Suez Canal) The Panama Canal cost the United States about 380 million dollars. 40 million was paid to the French for the Canal, 10 million to Panama for the land, and 20 million to sanitize the area of diseases and plagues (The World Book Encyclopedia, Panama Canal). The Suez Canal never had the problem of money because the person who started the canal finished it. The Panama Canal had problems due to the French starting the project, the diseases, the land, etc. The Suez was much more cost-efficient in comparison to the Panama Canal. The cost of locks was a burden to the Panama Canal, which leads me to my next theme. The Panama Canal has locks, water-filled chambers that raise and lower ships from one level of land to another. The Suez, on ...

Free At Last essays

Free At Last essays African-Americans were enslaved for over 200 years. While enslaved many were beaten to death. Their children were taken from them, and their daughters raped. They finally gained their freedom, at least thats what they thought. They were still being stigmatized for what they were not, white. Why did it surprise them? After all they lived in a nation that believed in social Darwinism, only the fittest will survive. To white America they were only ex-slaves, ignorant and an inferior race. The discrimination against the black men was so out of control that it even created Jim Crow laws. It also caused the Great Migration and created the New Negro. Jim Crow laws were passed in the Southern states. It legalized the segregation between blacks and whites. The name is believed to come from a character in a popular minstrel song. These laws created separate streetcars, public waiting rooms, theaters, and even hospitals. Even soldiers serving in WWI were being discriminated. They were good enough to fight for our country but to not good enough to be considered equal to his white counterpart because of his skin color. World War I ceased European immigration and because of this, businesses where looking to hire southern Africans. The poverty level and racism caused blacks to move up North.
