The P89V51RD2 is an 80C51 microcontroller with 64 kB Flash and 1024 bytes of data RAM.A key feature of the P89V51RD2 is its X2 mode option. The design engineer can choose to run the application with the conventional 80C51 clock rate (12 clocks per machine cycle) or select the X2 mode (6 clocks per machine cycle) to achieve twice the throughput at the same clock frequency. Another way to benefit from this feature is to keep the same performance by reducing the clock frequency by half, thus dramatically reducing the EMI
Each station will have a destination code, user have to type the destination code in-between two hash symbols and sent it to the toll free no (system end) So that the controller verifies the destination code and checks whether the user have sufficient balance, if so then it generates random no then sends it to the user mobile no simultaneously assigns printer to hold print certain data until a second enable from the controller , as soon as the user enter the random no via key pad controller sends printer the second enable , so that the user can collect the print out(ticket).
The system end will send reply SMS (5 digit random number) to user’s mobile phone.
The cost of the railway ticket will be reduced from mobile balance.
The random no along with the user ph no has to be entered in the keypad for collecting ticket.
Railway ticket will be collected from the thermal printer.
The GSM device receives all the data through the serial communicating device with a microcontroller kit and then sends data to the corresponding mobile. We have the data displayed in a mobile, which is considered as the SYSTEM END .
In this project we have two main units one is USER END (mobile phone) and another is SYSTEM END (Automatic Ticket vending machine which is placed in railway ticket counter).The user just have to send an SMS to get the railway ticket in reply from the SYSTEM END , user will receive FOUR digit password. This password has to enter in machine to receive a railway ticket. That cost of the railway ticket will be reduced from user mobile balance.
Having read horror and science fiction from an early age, King had developed an intuitive sense of what readers enjoy in a good horror novel. He uses abrupt plot twists for shock value and loves to create imaginary worlds where his characters no longer control their environment. In a Stephen King novel, the characters are completely at the mercy of others, whether those “others” are dark supernatural forces, strange monsters, flesh and blood villains or demons from within themselves.
Among his other interests, King occasionally finds time to play guitar in a rock band called the Rock Bottom Remainders, which is composed entirely of fellow authors, including humorist and columnist Dave Berry and Amy Tan.
His subsequent works explore witchcraft and various aspects of the occult to both frighten and delight the readers that make each one into a best seller. Notable among them are, which Salem’s Lot (1975), The Shining (1976), Firestarter (1980), Cujo (1981), Different Seasons (1982), Christine (1983), Pet Semetary (1983), Skeleton Crew (1986), The Tommyknockers (1987), The Dark Half (1989), The Stand (1990), Four Past Midnight (1990), The Darj Tower III: the Waste Lands (1991), Needful Things (1991), Gerald’s Game (1992) and Dolores Claiborne (1992). King also created an original screenplay for Sleepwalkers(1991).
An avid supporter of the US military, Clarcy works in an office lined with war games, books on weapons and government produced maps, all tributes to his lifelong fascination with technology and the military. In turn, he uses his books to advocate a strong American military posture.
The success of his books has resulted in his access to a wide variety of sources and information within military and intelligence intelligence circles that sets Clancy apart from other writers of military thrillers.
His first novel, The Hunt for Red October (1984), is about a Russian submarine captain who defects, along with his sub, to the United States was a best seller. The book reached The New York Times best-seller list after President Ronald Reagan pronounced it “the perfect yarn” and “non-putdownable.”
Notes for her strong advocacy of social justice Alice Walker’s early work included Revolutionary Petunias and Other Poems (1973), which earned a National Book Award nomination and a Lillian Smith Award from the Southern Regional Council and In Love and Trouble (1973), a series of stories about black women. Her book Meridian (1976) is considered one of the best novels of the Civil Rights struggle and You Can’t Keep A Good Woman Down (1981) combines that theme with her feminist ideals.
Since the early 1980s, Alice Walker’s works have included In Search Of Our Mother’s Gardens (1983); Horses Make a Landscape Look More Beautiful (1984); To Hell With Dying (1988); The Temple of My Familiar (1989)l and possessing the Secret of Joy (1992). She contributed to Double Stitch: Black Women Write About Mothers & Daughters (1993) and Everyday Use (1994).
Having graduated from Sarah Lawrence Collage in 1966, she was writer in residence and a teacher of black studies at Jackson State Collage (1968-1969), Tougaloo College (1970-1971), and a lecturer in literature at both Wellesley and the University of Massachusetts from 1972 to 1973.
In the 1960s, she was active in the support of the Civil Rights movement and she became an outspoken feminist in the 1970s.
His rough, angular face is best recalled, however, from his work as an actor in such films as Renaldo and Clara (1978); Days of Heaven (1978); Resurrection (1980); Raggedy Man (1981), Frances (1982); and as test pilot Chuck Yeager in The Right Stuff (1983), for which he was nominated for the best supporting actor Oscar. In this role, he portrayed a man much like the heroes in his own plays. He went on to play the lead in the film version of his own Fool For Love in 1985.
He has also appeared in Country (1984); Crimes of the Heart (1986); Steel Magnolias (1989); Hot Spot (1990); Bright Angel (1991); Defenseless (1991); Thunderheart (1992), and The Pelican Brief (1993)
Sam Shepard has also penned a number of screenplays that pursue his themes of rebellious loners in a violent or hostile world, many of which are based on his plays. Among them are Me and My Brother (1967) Zabriski Point (1970) and Renaldo and Clara (1978) as well as his great Fool For Love (1986). In 1983, German director Wim Wenders commissioned him to adapt his 1982 book motel Chronicles for the screen. The result was the screenplay for Paris, Texas (1984), which won the Golden Palm Award at the Cannes Film Festival. It was the story of a reunion of father and son.
His best-known work is the 1983 play Fool for Love, which won an Obie Award. It is a story of love and incest set in the American West.
Continuing to explore the mythic dimensions of Western lore, he published The Sad Lament of Pecos Bill on the Even of Killing His Wife in 1983. He followed this with A Lie of the Mind (1985), which won the New York Drama Critic’s Circle Award 1986).

Socrates, a Greek philosopher, preached the principle that knowledge is also power. Plato, another Greek philosopher, gave his people the idea of philosopher king’s rule. He favoured a government run by intellectuals and specialists.
Great intellectuals have worked for the welfare of the people. In India, we have the Rajya Sabha, the Upper House, comprising intellectuals representing different walks of life. Their expertise is made use of. Members of the Rajya Sabha deliberate with a view to prodding the government to take welfare measures for the welfare of the people. They give liberally of their time and would not brook any injustice.
Their sacrifice is tremendous. For instance, Socrates had to drink hemlock. Jesus Christ was crucified. Karl Marx, who wrote Das Kapital suffered hardships. Swami Dayanand was poisoned. Mahatama Gandhi was shot by a fanatic.
Karl Marx, died in squalor, but he gave new hope to the neglected working class. Jesus Christ who gave a message of love and compassion to mankind became immortal when he was crucified. Gandhi gave his life preaching non-violence, truth, service and brotherhood. Intellectuals have a humanizing role in society.
Intellectuals, by and large, live for others. Lenin devoted his life for the upliftment of the working class. In India, Gandhi preached truth and non-violence as a way of life. He wrested power from the British through satyagraha a novel peaceful technique. Gandhi became a martyr like Socrates and Jesus Christ.
By their revolutionary ideas, intellectuals were able to bring about vast changes in the state and society. The ideas evolved and propounded by Gautam Buddha, Adi Shandaracharya, Nanak, Dayanand, Ramakrishna Paramhans, Vivekananda and others have had profound affect on the life of Indians. Their teachings hold good to this day. Today there is so much stress and strain around the life and teachings of these intellectuals give us peace and show us the way. We learn the art of living.
India, now needs most the intellectuals in different professions. Communalism is raising its head. Regionalism is dividing the people on linguistic lines. Anti-national and separatist forces are surfacing. Terrorism sponsored by a neighbor is on the increase.
Social evils remain. Corruption is found here and there. The country stands at the cross roads to follow the same path as in the past or to follow a new path leading the country to lasting peace, progress and prosperity. In the latter case, intellectuals have a great role to play.

Teflon was invented accidentally by Roy Plunkett of Kinetic Chemicals in 1938. Plunkett was attempting to make a new CFC refrigerant, the perfluorethylene polymerized (say that 3 times fast!) in a pressurized storage container. In this original chemical reaction, iron from the inside of the container acted as a catalyst.
Like many artificial sweeteners, the sweetness of cyclamate was discovered by accident. Michael Sveda was working in the lab on the synthesis of anti-fever medication. He put his cigarette down on the lab bench and when he put it back in his mouth he discovered the sweet taste of cyclamate. Cancer inducing Aspartame was discovered in 1965 by James M. Schlatter, a chemist working for G.D. Searle & Company. Schlatter had synthesized aspartame in the course of producing an anti-ulcer drug candidate. He discovered its sweet taste serendipitously when he licked his finger, which had accidentally become contaminated with aspartame.
Initially wine was distilled as a preservation method and as a way to make the wine easier for merchants to transport. It was also thought that wine was originally distilled to lessen the tax which was assessed by volume. The intent was to add the water removed by distillation back to the brandy shortly before consumption. It was discovered that after having been stored in wooden casks, the resulting product had improved over the original distilled spirit. No one is sure who it was that discovered the delightful taste of this distilled liquor, but he was clearly guided by God in its discovery for the betterment of man.
And the forth Accidental discoveries is
Percy LeBaron Spencer of the Raytheon Company was walking past a radar tube and he noticed that the chocolate bar in his pocket melted. Realizing that he might be on to a hot new product he placed a small bowl of corn in front of the tube and it quickly popped all over the room. Tens of millions of lazy cooks now have him to thank for their dull food!
now don't just sit around go bake something for you to munch on...

Some of man’s greatest discoveries have been made entirely by accident. If it weren’t for many of these things, life would be very different for us.
A Scientist named Sir Alexander Fleming was studying Staphylococcus long ago(seriously i don't know whats that).He turned up at work one day and discovered a blue-green mould that seemed to be inhibiting growth of the bacteria. He grew a pure culture of the mould and discovered that it was a Penicillium mould.After further experiments, Fleming was convinced that penicillin could not last long enough in the human body to kill pathogenic bacteria, and stopped studying it after 1931, but restarted some clinical trials in 1934 and continued to try to get someone to purify it until 1940.
(guys no offense OK)
