Virus Attack on Computers, Mobiles And Palmtops (SEMINAR TOPIC)

INTRODUCTION

Do viruses and all the other nasties in cyberspace matter? Do they

really do much harm? Imagine that no one has updated your anti- virus software for a few months. When they do, you find that your accounts spreadsheets are infected with a new virus that changes figures at random. Naturally you keep backups. But you might have been backing up infected files for months. How do you know which figures to trust? Now imagine that a new email virus has been released. Your company is receiving so many emails that you decide to shut down your email gateway altogether and miss an urgent order from a big customer. Imagine that a friend emails you some files he found on the Internet. You open them and trigger a virus that mails confidential documents to everyone in your address book including your competitors. Finally, imagine that you accidentally send another company, a report that carries a virus. Will they feel safe to do business with you again? Today new viruses sweep the planet in hours and virus scares are major news.A computer virus is a computer program that can spread across computers and networks by making copies of itself, usually without the user’s knowledge. Viruses can have harmful side effects. These can range from displaying irritating messages to deleting all the files on your computer. A virus program has to be run before it can infect your computer. Viruses have ways of making sure that this happens. They can attach themselves to other programs or hide in code that is run automatically when you open certain types of files. The virus can copy itself to other files or disks and make changes on your computer. Virus side effects, often called the payload, are the aspect of most interest to users. Password-protecting the documents on a particular day, mailing information about the user and machine to an address somewhere are some of the harmful side effects of viruses.address somewhere are some of the harmful side effects of viruses.Password-protecting the documents on a particular day, mailing information about the user and machine to an Various kinds of viruses include macro virus, parasitic or file virus, Boot virus,E-mails are the biggest source of viruses. Usually they come as attachments with emails. The Internet caused the spreading of viruses around the globe. The threat level depends on the particular code used in the WebPages and the security measures taken by service providers and by you. One solution to prevent the viruses is anti-virus softwares. Anti-virus software can detect viruses, prevent access to infected files and often eliminate the infection.Computer viruses are starting to affect mobile phones too. The virus is rare and is unlikely to cause much damage. Anti-virus experts expect that as mobile phones become more sophisticated they will be targeted by virus writers. Some firms are already working on anti-virus software for mobile phones. .......for complete information contact us or leave email id in message box.

VIRTUAL SURGERY(SEMINAR TOPIC)

ABSTRACT

Rapid change is under way on sever fronts I medicine and surgery. Advance in computing power have enable continued growth in virtual reality, visualization, and simulation technologies. The ideal learning opportunities afforded by simulated and virtual environments have prompted their exploration as learning modalities for surgical education and training. Ongoing improvements in this technology suggest an important future role for virtual reality and simulation in medicine.

INTRODUCTION

Rapid change in most segments of the society is occurring as a result of increasingly more sophisticated, affordable and ubiquitous computing power. One clear example of this change process is the internet, which provides interactive and instantaneous access to information that must scarcely conceivable only a few years ago.

Same is the case in the medical field. Adv in instrumentation, visualisation and monitoring have enabled continual growth in the medical field. The information revolution has enabled fundamental changes in this field. Of the many disciplines arising from this new information era, virtual reality holds the greatest promise. The term virtual reality was coined by Jaron Lanier, founded of VPL research, in the late 1980’s. Virtual reality is defined as human computer interface that simulate realistic environments while enabling participant interaction, as a 3D digital world that accurately models actual environment, or simply as cyberspace..

Virtual reality is just beginning to come to that threshold level where we can begin using Simulators in Medicine the way that the Aviation industry has been using it for the past 50 Years — to avoid errors.

In surgery, the life of the patient is of utmost importance and surgeon cannot experiment on the patient body. VR provide a good tool to experiment the various complications arise during surgery….........................

I Capture the Castle (1948) A novel by Dodie Smith

This is the journal of Cassandra Mortmain; an extraordinary account of life with her extraordinary family. First, there is her eccentric father. Then there is her sister, Rose - beautiful, vain and bored - and her stepmother, Topaz, an artist's model who likes to commune with nature. Finally, there is Stephen, dazzlingly handsome and hopelessly in love with Cassandra.

In the cold and crumbling castle which is their home, Cassandra records events with characteristic honesty, as she tries to come to terms with her own feelings. The result is both marvellously funny and genuinely moving.

The god of small things By Arundhati Roy

The story of the tragic decline of an Indian family whose members suffer the terrible consequences of forbidden love, The God of Small Things is set in the state of Kerala, on the southernmost tip of India. Armed only with the invincible innocence of children, the twins Rahel and Esthappen fashion a childhood for themselves in the shade of the wreck that is their family -- their lonely, lovely mother, Ammu (who loves by night the man her children love by day), their blind grandmother, Mammachi (who plays Handel on her violin), their beloved uncle Chacko (Rhodes scholar, pickle baron, radical Marxist, bottom-pincher), their enemy, Baby Kochamma (ex-nun and incumbent grandaunt), and the ghost of an imperial entomologist's moth (with unusually dense dorsal tufts).

When their English cousin and her mother arrive on a Christmas visit, the twins learn that Things Can Change in a Day. That lives can twist into new, ugly shapes, even cease forever. The brilliantly plotted story uncoils with an agonizing sense of foreboding and inevitability. Yet nothing prepares you for what lies at the heart of it.
