Bar code distinguish fast and high veracity  ¼Ã…’great fiexiblityà £Ã¢â€š ¬Ã¢â‚¬Å¡But, because of the Bar code only in one direction (horizontal) commonly show information. So the data capacity is small. Bar code often need to connect to the database in order to get more data from the network by limited information capacity. But Bar code will loses the role in under the condition of not forget or database. The QR code use Bar codes information stored way extension in the two-dimensional space, do not need to connect a database, it can store large data by itself, it is high density large capacity. QR code also have wide coding, high recognition rate, difficult to abrasion .low cost etc.It can be printed in newspapers and magazines and periodicals,let people use mobile phone to reader it.

Thomas Hardys Tragic Stories Essay -- Biography Biographies Essays

Thomas Hardy's Tragic Stories For centuries, various writers have endeavored to encapsulate the constituents of tragedy, and create works of literature that adhere to their understanding of an ostensibly universal system of tragic structure, tragic plot, and tragic theme. Nevertheless, the etymology of the word, "tragedy," proves to be as elusive and arcane as the tragic construct is seemingly concrete and unequivocal; indeed, the word, "tragedy," can be traced to the Greek word, "tragoidia," which literally means, "goat-song." We do not know whether actors in the Choral Odes read their lines clad in goatskins, or if goats were bestowed as prizes; we do know, however, that Aristotle reconfigured the more bucolic play tradition, and, in his Poetics, developed a technique founded on the tradition of regal grandeur, sweeping scope, and cosmic power. Thomas Hardy, one of the few Victorian tragic prose writers, undoubtedly draws from the tradition of Aristotelian Greek tragedy. Nevertheless, our thesis expresses skepticism in the precision and alacrity with which Hardy is equated with tragedy and conventional tragic form. In a post-Shakespearean nineteenth-century world, writers were acquainted with two tragic traditions: Greek and Christian. The Greek tragic tradition is founded upon the ritual feasting of Dionysus (or the Roman version, Bacchus); the Christian mystery play tradition is rooted in the Passion of Christ. Both traditions bind themselves inextricably to forces larger than themselves - either to gods and goddesses, or to the Holy Trinity - and structure their plays around the rituals inherent in these traditions. Hardy's own novels comprise elements of both Greek and Christian tragic conventions, thus elici... ...on tragedy from The Life and Work of Thomas Hardy Bibliography Bloom, Harold.

Media highlights the aspects, which were not existent before. The world has become smaller and smaller and its advancements have been all thanks to the constant alarming of mass media. Despite the fact that news makes the international scenarios and us aware of the local it sometime, become a red devil itself. Discussion News is the source of gathering all the information needed to keep the people up to date with the latest trends and happenings. People now days get access to the news whenever they want. The main sources of tuning to the news include television, radio, newspapers, magazines and more of late the World Wide Web. Even the cellular services are not far behind as they keep people informed while one is away from the above mediums. Therefore, it is not necessary whether you are connected to these mediums or not, you can probably use your cell phone to get the latest updates. News and the media treat all people alike, as it has no personal contacts between the senders and receivers. Most of the times the news media can turn out to be the devil rather than an angel. It is better to say that media manipulates its role in such a way that people might be unable to understand their POV (Paul & Dennis, pp 2-4). Prime example being the terror attacks of 11 September 2001. Many news channels and other media officials highlighted in their own perspective and ways. According to them 9/11, relate with the understanding of current events (Tom, pp 6-7). Others do not even come close to the topic as they think it is useless to talk about what they do not know. The news media creates the doubt of the individuals specially those who suffered the wrath of 9/11 and other similar terrorist activities. Conclusion The days of living like unaware person are no way possible in the modern era. The mainstream media has totally affected the life of individuals by all leaps and bounds. Today no person can think of surviving while the news media is running the show. In the days when internet was not very popular, newspapers were considered as the ultimate source of information. The news is helpful in gaining access to the new and contemporary information regarding lifestyle, sports, entertainment etc. At the same time, they play a negative role towards the psyche of an individual. The news media must play the role both informative and responsible, as there are many who cannot bear the sight of bad news in form of terrorism or other similar news.
