Everyone:

Hello!

I am a third year master major in automation at ×× University, P. R. China. With tremendous interest in Industrial Engineering, I am writing to apply for acceptance into your Ph.D. graduate program.

Education background

In 1995, I entered the Nanjing University of Science & Technology (NUST) -- widely considered one of the China’s best engineering schools. During the following undergraduate study, my academic records kept distinguished among the whole department. I was granted First Class Prize every semester,In 1999, I got the privilege to enter the graduate program waived of the admission test.

At the period of my graduate study, my overall GPA(3.77/4.0) ranked top 5% in the department. In the second semester, I became teacher assistant that is given to talented and matured students only. This year, I won the Acer Scholarship as the one and only candidate in my department, which is the ultimate accolade for distinguished students endowed by my university. Presently, I am preparing my graduation thesis and trying for the honor of Excellent Graduation Thesis.

Research experience and academic activityWhen a sophomore, I joined the Association of AI Enthusiast and began to narrow down my interest for my future research. With the tool of OpenGL and Matlab, I designed a simulation program for transportation scheduling system. It is now widely used by different research groups in NUST. I assumed and fulfilled a sewage analysis & dispose project for Nanjing sewage treatment plant. This was my first practice to convert a laboratory idea to a commercial product.In retrospect, I find myself standing on a solid basis in both theory and experience, which has prepared me for the Ph.D. program. My future research interests include: Network Scheduling Problem, Heuristic Algorithm research (especially in GA and Neural network), Supply chain network research, Hybrid system performance analysis with Petri nets and Data Mining.

Thank you!

Four years’ university education gives me a lot of things to learn,a lot of chances to try,and a lot of practices to improve myself.It teaches me not only what to study and how to think,but also to see the importance of practical ability (such as doing expriment as much as possible). In the university life,i have made many good friends.They help me improve my study and research ability, do ererything just like a man,and often give me good example to follow.

Besides what i have introduced myself above,i also have many interests in my spare time.I like playing football,which is an effective way i think to improve my body health,and it can teach me how to join in a group and deal with other people.Drawing and writing is another favor to me.

Above all,i choose the major in order to broad my view in biology scince,and enhance my research ability.I will do my best to join the new group and be good at postgraduate study.

Dear Tom,

I`m happy to share my opinion about hometown，shijiazhuang. Today,shijiazhuang is quite different from ten years ago.In the past,there was a little road in the city,and the road was very narrwo.As there is the capital city of Hebei Province,the traffic was very heavy.But there have built a lot of roads in these years,and all of these are broad.

There were only 3 parks in the city at ten years ago,and the air pollution was very serious.However,there are a great many of new parks were built.People often go to the nearest park do morning excise,and children also enjoy there.Of course,the air also improved a lot.

Today`s shijiazhuang is a beauty and modern city ,welcome to my hometown with your family.

Hello everyone！ My name is * * *, from Jiangsu * *. Very pleased to enter the academic atmosphere of the * * * * college. After all, for every student, public undergraduate is a dream that is worth working through. Today, it is becoming the youth of the post, dream of the stage, the struggle of the blue sky.

For this was rooted in the heart of the dream, we work hard, we fought in the busy high school life, we only know must strive to finish each paper, do well every quality inspection, in each examination room are outstanding. We dont even have time to ask ourselves if its going to be hard work.

Today, I finally arrived at * * * and came to the beautiful campus of the university. Actually, in March of this year, I stepped into this city with a long history for 4 times. However, the legend of the picturesque scenic spots: Dr. Sun Yat-sens Mausoleum, Mochou Lake, the Qinhuai River, Confucius temple, I never want to see. Those famous snacks, I did not want to have a try. I dont want to go shopping in those busy commercial centers in Xinjiekou.

Why? Because I am very clear, I came to * * *, the purpose is to participate in the art of radio and television director of the examination. I remember when I gave myself a chance to choose more, and in the confused eyes of my teachers and classmates, I often played the violin on my back, and took the south train at 4 in the morning.

What kind of day is that? While at the same time to course review, while also practicing the violin concerto butterfly, while reciting the historical geography textbooks, while also have time to read reviews, stories, practice commentary, prepared speech. Even with some basic drawings, I dare not relax. You may know: at Nanjing Arts Institute was next to a park, I took the examination room to see from the south, first, look at the list, and then to go to the provincial exam retest, located south Normal University, I dont know how many times through to a total of 8 times, this park? Or maybe the 10 time? But even today, I dont know what the name of that park is

When the Nanjing Arts Institute professional examination scores down, the provinces fifth results did not bring me joy. I am still in learning, in practice, a tiny bit are not slack. The teacher said, "you have got a good result in the cultural class. Why do you want to do art?" Students say: your violin level already by the China Conservatory of Music grade 8 examination, why practicing until late at night? I dont know how to answer. I just have to try and even try my best. In order to dream, in order to be able to enter the University hall.

Finally, my dream came true. I love art, but I love Chinese language and literature more. Although I gave up art, but art has shed sweat and no waste, because art is able to help us better understand the literature, literature and art combined with each other, a beautiful flower, bear the fruit of happiness.

I sincerely hope that with the help of teachers and students, I can bring my special skills in art field into full play in Chinese language and literature. We can have the opportunity to contribute to our professional development and the development of our school.

Thank you all!

Please look at the new building over there. Its ourlibrary that was painted white again this year. It not only looks morebeautiful, but also has increasingly more books than before. Reading differentkinds of books can enhance our horizons and increase our knowledge. I stillremember I entered the school two years ago, the library was old enough and Ialways couldnt find my favorite comic books. Therefore, I often complained tomy classmates that the library was out of fashion that we were not able tolearn fresh knowledge in it.

What was even worse, as a member of school basketballteam, my partners and I had few chances to practice, as the playground was toosmall to play andfull of so many students after school. Luckily, I dont haveto worry about that anymore, because our playground is large enough for all ofus to play games, and basketball court is also bigger. Thats wonderful!

My school has changed a lot, for it is more beautifuland modern. I love my school.

The large number of our population has become one of the most serious problems of our society. according to a recent survey of the national bureau of statistics, there are more than 1.3 billion people in our country, which account for about 1/5 of all the people in the world. the same survey also predicts that our population will grow quickly in the years to come.

overpopulation has brought about a series of negative effects to our economic development and social security. in the first place, too many people impose a heavy burden on our environment. as a result, we suffer from a shortage of fresh water and natural resources. in the second place, as the supply of labor greatly exceeds the demand of the society, many people become employed. this is a source of social unrest. last but not least, we have to manufacture all kinds of products to meet the needs of the people, which causes environment pollution to our lakes and land.

serious though the problem seems, we have to take some measures to tackle it. on the one hand, the government should carry out more strictly the policy of family planning, thus reducing the total number of population. on the other hand, all the people should realize the harms of overpopulation. with the concerted efforts of all the parties concerned, we’re sure to solve the problem in the future.
