Research experience and academic activity

When 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 schedul-ing 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 Schedul-ing Problem, Heuristic Algorithm research (especially in GA and Neural network), Supply chain network research, Hybrid system performance analysis with Petri nets and Data Mining.

During the following undergraduate study, my academic records kept distinguished among the whole department.

I was granted First Class Prize every semester, and my overall GPA(89.5/100) ranked No.

1 among 113 students.

In 1999, I got the privilege to enter the graduate program waived of the admission test.

I selected the Shanghai Jiao Tong University to continue my study for its best reputation on Combinatorial Optimization and Network Schedu ling where my research interest lies.

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 activity，When a sophomore, I joined the Association of AI Enthusiast and began to narrow down my interest for my future research.

In 1997, I participated in simulation tool development for the schedu ling system in Prof.

Wang’s lab.

With the tool of OpenGL and Matlab, I designed a simulation program for transportation schedu ling system.

It is now widely used by different research groups in NUST.

In 1998, 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 1999, I joined the distinguished Professor Yu-Geng Xis research group aiming at Network flow problem solving and Heuristic algorithm research.

Soon I was engaged in the FuDan Gene Database Design.

My duty was to pick up the useful information among different kinds of gene matching format.

Through the comparison and analysis for many heuristic algorithms, I introduced an improved evolutionary algorithm -- Multi-population Genetic Algorithm.

By dividing a whole population into several sub-populations, this improved algorithm can effectively prevent GA from local convergence and promote various evolutionary orientations.

It proved more efficiently than SGA in experiments, too.

In the second semester, I joined the workshop-schedu ling research in Shanghai Heavy Duty Tyre plant.

The schedu ling was designed for the rubber-making process that covered not only discrete but also continuous circumstances.

To make a balance point between optimization quality and time cost, I proposed a Dynamic Layered Schedu ling method based on hybrid Petri Nets.

The practical application showed that the average makespan was shortened by a large scale.

I also publicized two papers in core journals with this idea.

Recently, I am doing research in the Composite Predict of the Electrical Power system assisted with the technology of Data Mining for Bao Steel.

I try to combine the Decision Tree with Receding Optimization to provide a new solution for the Composite Predictive Problem.

This project is now under construction.

Besides, In July 2000, I got the opportunity to give a lecture in English in Asia Control Conference (ASCC) which is one of the top-level conferences among the world in the area of control and automation.

In my senior year, I met Prof.

Xiao-Song Lin, a visiting professor of mathematics from University of California-Riverside, I learned graph theory from him for my network research.

These experiences all rapidly expanded my knowledge of English and the understanding of western culture.

I hope to study in depth .

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 Schedu ling Problem, Heuristic Algorithm research (especially in GA and Neural network), Supply chain network research, Hybrid system performance analysis with Petri nets and Data Mining.

Please give my application materials a serious consideration.

Thank you very much.

扬州是一座历史名城。下面是小编整理分享给大家的介绍扬州的优秀英语作文，欢迎阅读鉴赏。希望大家喜欢！

Yangzhou (simplified Chinese: 扬州) is a prefecture-level city in central Jiangsu Province, Peoples Republic of China. Sitting on the northern bank of the Yangtze River, it borders the provincial capital of Nanjing to the southwest, Huaian to the north, Yancheng to the northeast, Taizhou to the east, and Zhenjiang across the river to the south. Historically it is one of the wealthiest of Chinas cities, known at various periods for its great merchant families, poets, painters, and scholars.

Geography and climate

Rivers: the Yangtze River, Jinghang Canal, Baoshe River, Datong River, Beichengzi River, Tongyang Canal, Xintongyang Canal, Baima Lake, Baoying Lake, Gaoyou Lake, Shaobo Lake.

Local landscape: Slender west lake, Ge garden, He garden, Da ming temple, Phoenix island, etc. Subtropical monsoon climate with humid changeable wind; longer winters for about 4 months, summers 3 months and shorter springs and autumns, 2 months respectively; frost-free period of 222 days and annual average sunshine of 2177 hours. Average temperature: 15 °C annually; the hottest in July of 27.6 °C and the coldest in January of 1.7 °C; maximum temperature of 39.8 °C and minimum 19 °C

The annual average precipitation is 1,030 mm, and about 45 percent of rainfall is concentrated in the summer. The rainy season known as "plum rain season" usually lasts from mid-June to late July. During this season, the plums are ripening, hence the name plum rain.

Cuisine

Yangzhou dishes may be one of the reasons why the people of Yangzhou are so infatuated with their city. They have an appealing color, aroma, taste and appearance. The original color of each ingredient is preserved after cooking, and no oily sauce is added, so as to retain the fresh savor of the food.

In Yangzhou all dishes, whether cheap or expensive, are elaborate. Cooks will not scrimp on their work, even with Zhugansi (stewed sliced dry bean curd), a popular dish that costs only a few yuan. Dry bean curd is made by each restaurant that serves it, so the flavor is guaranteed. The cook slices the 1-cm-thick curd into 30 shreds, each one paper-thin but none broken, and then stews them for hours with chopped bamboo shoots and shelled shrimps in chicken soup. In this way the dry bean curd shreds can soak up the flavor of the other ingredients, and the soup is clear but savory. It is not only Yangzhou cooks but also the ordinary people who are conscientious about cooking.

My father is a very respectable man in the world.Although he is not tall and strong as any of the heroes described in the novels,not handsome as any of those stars of stage and screen, he is the greatest man in my eyes.As a worker in a steel factory, he worked hard for me and my mother in his whole life, none penny was spent for himself.

He would never buy drinks on street under the torrid noonday sun for saving money to buy me an ice-cream.

cheerful，open-minded,warm-hearted...all nice words I can put on my dear father.

you would have fun with him all day long during the talk with him.

He is a very easy-going man so thats why he has so many friends.To help anyone who ever or never helped us means a lot to him.

I love my dad as I love myself, i pray to God that He could let me be his daughter in my next life if there is...

Good morning Sir, (What will you say if it is a woman?)

I am glad to be here for this interview. First, let me thank you for finding time in the midst of pressing affairs.

I am 25 years old and I am local. (I live locally sounds better) I am seeking an opportunity to work with XXX as Sales. (IN sales or As a Sales representative/whatever)。My professional experience and my awareness of your unparalleled reputation have led me to want to work for your company.

I have a bachelor degree with a major in Mechanical and Electrical field.(pause) Graduated from the XXX university in 20xx. Over the past three years, I have worked with XXX Co.,Ltd as Sales (again, in sales or as a sales man/person/rep?) who responsible (with responsibility mainly) for the market of Hunan. During this period, I have learnt much. I learned the values of teamwork and commitment, how to win, how to work hard, how to concentrate and focus on goals, and how to balance my time and priorities. Additional experience in other fields such as graduation practice in factory and commercial negotiation also reinforces my value to your company.

I enjoy thinking, enjoy learning, enjoy working, (and I am )able to bear work pressure.

In my free time, I often participate (in) activities such as table tennis (and) badminton.

I am expecting to become your colleague on some day. (More tactful to say ’I would love to become you colleague/join the company)

Because being offhand in advance, let’s leave it at that. (This sentence makes no sense. ’Being offhand’ means to be rude, inconsiderate, ill-mannered so I don’t think that is whay you mean! In advance of what? ’Let’s leave it at that’ is a command, it sounds rather abrupt and ill-mannered to me, again I don’t think this is what you meant. How about ’I would love to join your company and you would not regret giving me this opportunity.’ and just finish with a smile!)

Thanks.

Sichuan is located in the Upper Yangtze Valley in the southwestern part of the country. The second largest of the Chinese provinces, it covers an area of 220,100 square miles (570,000 square kilometres). Szechwan is bordered by the provinces of Kansu and Shensi to the north, Hupeh and Hunan to the east, and Kweichow and Yunnan to the south and by the Tibet Autonomous Region to the west and the province of Tsinghai to the northwest. It is the most populous province in China. The name Szechwan means “Four Streams” and refers to the four main tributaries of the Yangtze River, which flows through the province. The capital, Cheng-tu, is located in the centre of the province.

From economic, political, geographical, and historical points of view, the heart and nerve centre of Szechwan is in the eastern basin area, commonly known as the Sichuan, or Red, Basin. Its mild and humid climate, fertile soil, and abundant mineral and forestry resources make it one of the most prosperous and economically self-sufficient regions of China. The area has been seen by some as China in a microcosm and is often viewed as a country within a country. The Chinese call the basin Tien Fu Chih Kuo, which literally means “Heaven on Earth”.

Dad grew up in a single parent family, perhaps this is not perfect family created his fathers reticent character. Until there is me, my father will always have some smile.

Perhaps the boys heart and personality accounted for the upper hand, my father earnestly told me reason, I always disdain, turn a deaf ear, or severely refute a pass. In this regard, my father just silently smoking. I thought it was naive. Can learn no fathers urging, the results naturally fell. At that moment, although my father did not hit me, but the death of the general silence, desperately smoking, my father greeted his face showing disappointment look. I am determined, must be in the study and life to achieve success, by praise. Let my father show a rare smile.

Dads smile is more out of my sensible. That day at noon to eat fish, my father was a big fish caught, rice balls, water, steamed bread swallowed, are of no avail. Cross here is painful, my father kept moaning. I am very worried. Home school at night, I still do not worry that hateful fishbone, even homework is also absent-minded. Dad a home, I asked: "Dad, the fish did not go down?" "Go on!" Dad smiled, it seems very satisfied.

My mom and dad may not be the best, but love me; my mom and dad may not be the best, but in my heart is the most beautiful of the most handsome. Because one thing makes me know my mom and dad is the best. Do not lose someone elses mom and dad.

I remember when I was four years old, I came back from the kindergarten, finished homework on the outside and the children play games ----- turn. I called my mother bought me a product of orange Shuang, is a glass bottle to do, I and the children turn when the halo, it fell to the ground, the glass bottle to scratch my face, out of a lot of blood Well, left a deep mark, when I touch my face, I am very sad, Mom and Dad also tears.

Blink of an eye I was twelve years old, on the sixth grade.

Now I read the sixth grade, see my mother and dad for my little early test is good, busy busy busy, almost every day I will flow a tear, my mother sitting on the sofa, I saw my mothers white hair and more; to the father of tea Daddy has lost a lot. See my mom and dad so worried about me, I have no reason not to learn, I have no reason in such a good environment do not seriously study, I have no reason not to listen to my mothers father. Mom and Dad do not have to worry about me, why do they worry about me, because I do not listen, do not study hard. So I went to junior high school, I must change their own, I want to become obedient, good learning good boy. Mom and Dad often say where it does not matter, as long as the attitude, hard to learn, so good test a good high school, so I should attitude to positive, good learning.

Mom and Dad, so I am in junior high school, and I will become more sensible, I want for you, for me, for my grandfather grandmother, good study. Will not let you worry.

When I was five years old, my mother decided to send me to learn dance

class, at first, I was afraid, because I knew nobody there. But as when I went

there, I found there were a lot of children who were at my age, we became
