1)   Personal Statement
As Harbin Institute of Technology’s first and, currently, only student studying toward three simultaneous degrees in Electrical Engineering, Computer Science, and Business Administration, I am often asked by my peers where I gathered all the energy to even think about doing this. My answer to them is that if they had lived their childhood in a remote isolated town like mine, a place with virtually no learning opportunities,  and then one day through their efforts, they had the chance to study at one of China’s top Science and Engineering universities, it would be only natural that they would want to devote all they have to absorb the world of information available to them. Realizing no student from our small town’s high school had ever gone to college, my parents, with great expectations for me, sent me away to live with my grandparents in the city the year I finished elementary school. At age 11, I assumed the responsibility of becoming a top student in my class and taking good care of my often sick and aged grandparents. Those days were tough. I was so eager to please my parents and to fill the mixed determination and guilt they felt for letting me leave home to break a path for my future at such a young age that I not only worked diligently at school but also did all the labor at my grandparents’ house.
My hard work paid off. In***, at age 17, I was admitted as the youngest student in my class to the school of my dreams, III. Majoring in Electrical Engineering, I was ranked second in my class in my freshman year and won a Freshman Scholarship. Due to my excellent academic performance, when an opportunity to major in Business Administration, in addition to Electrical Engineering, came during my sophomore year, I did not hesitate to throw myself into this program. This special program requires an average GPA of 80/100 and a “pass” grade on every final exam. Failure to meet these requirements would result in automatic disqualification in the second major. Engaging in this program certainly doubled my workload. However, I deem it worthwhile since the experience stretched my potentials, improved my abilities on a broader scale, and provided me with a wider vision than that of my peers. Though this process was difficult, requiring many midnight study sessions in poorly lit and even more poorly heated student dormitories, I managed to maintain the No.2 standing in my class.
My desire to take full advantage of III’s dynamic academic atmosphere and my positive experiences of succeeding in two majors boosted my confidence and drove me to take on further challenges. In my junior year, I enrolled myself in the Computer Science program as my minor. This program requires an average minimum GPA of 75/100 and “pass” on every final exam. Although the additional coursework required me to give up even more of my virtually nonexistent free time, I greatly enjoyed learning various aspects of Computer Science, including software programming and hardware design. My computer knowledge has benefited me greatly in my current research. My optimistic character, high intelligence, determined attitude, and, most of all, my persistent hard work won me a Research Assistant position in a research group led by Professor FFF, a well-known scientist in the Electrical Engineering field and a distinguished faculty member at our university. I was so intrigued by our research that instead of returning home that summer, I spent my entire break conducting research on the “Use of CCD Digital Cameras in Satellites.” Our research currently focuses on two aspects: (1) simulating and modulating the CCD digital camera, and (2) building data structures and programming adapted software to interpret the data.
Through this research, I gained substantial firsthand experiences in applying the theories I have learned in classes to real life research. After painstaking efforts of testing and validating various models, our group succeeded in setting up a working model. We are now working to find good algorithms to integrate with the data.
Professor FFF was so deeply impressed by my excellent performance and maturity that he suggested I go abroad to pursue graduate study. To prepare for this, adding to my already full workload, I used my early mornings and late nights to study for the TOEFL and GRE and took them in my junior year. As a result, I successfully passed the most intensive period of my academic career to date and scored a high***on the GRE.  
Every time my friends ask me how I can handle all my responsibilities, I tell them if a person enjoys what they are doing, the workload seems much lighter. As much as I am interested in my studies, I have not limited myself to only classes and researches. I served as the Vice Student Chairman of my class, as well as the Student Representative for several courses. I am an active member of III’s reading and dancing clubs. Reading is my hobby. I enjoy reading biographies of great people such as Einstein, Fayman, Bill Gates, Carnegie, Napoleon, and Hill. I am also very interested in Psychology and have read many books by Freud and Jung. Reading in my spare time not only helps me relax but also constantly lifts my spirits and gives me with more energy to go further.
As I am graduating from college with three degrees, I am looking forward to going even further than what I have accomplished so far. Looking back on my difficult experiences at a young age and my determination to succeed at whatever tasks I set my eyes on in college, I am proud that I have become a goal-oriented man with integrity, diligence, and determination. I have become the person that my parents had hoped I would become. I have full confidence that I will succeed in your prominent program. I plan to devote all my energy to conduct research with your distinguished professors and to continue to excel.

2)     Statement of Purpose
A debate has existed since the last century about whether or not a machine will ever be able to imitate all that a human being does. Can we possibly create thinking, feeling, and intelligent beings? This question is the driving force behind my strong interest in Artificial Intelligence (AI). My aspiration to be an AI scientist dates back to my early childhood. Artificial Intelligence is so intriguing to me that I have always been totally fascinated by the splendid expectations of the future of AI technology. Even though there have been no great breakthroughs in AI field over the past twenty years, there are still some people working hard on it. I am one of those who believe that one day AI will contribute to the world in its magic way, but not the way of “Terminators” in sci-fi movies.
I began my research in the field of Artificial Intelligence when I was a graduate student at XX University. In XXXX, my first AI model, “Neural Network System for Test” (Version 1.0, Alfa), was used for model recognition and was successfully developed independently by applying feed forward NNs and Hebb study rules. I then developed the Beta version with feed forward NNs and Backpropagation algorithm, also called the supervised learning model and widely used in some practical fields. Following these two successful models, I started to develop the “Neural Network System for Test” (Version 1.0, Gamma) with advanced inheritance algorithm, and Hopfield feedback network system (Version 1.0, Theta) to simulate a dynamic nonlinear system. Additionally, with the programming experience of these AI models, I developed a new algorithm for computer graphics that was published on Computer Graphics “20XX International Academic Publishers”. These experiences have given me a great opportunity to understand the nature of Artificial Intelligence, and have strengthened my confidence to become a scientist.
Although I have achieved many successes in developing AI models and algorithms in the past three years, I still feel that I have not dug deep enough in the AI field. As I proceed with my research, I have come to realize that a more advanced and systematical study of Artificial Intelligence and Algorithm is necessary for my future research career as a scientist. In many people’s eyes, AI is simply a kind of trivial “Computing Technology” based on its mathematical theory; however, I believe that someday in the near future, our dream of “self-evolution of machines” will surely come true. For the pursuit of this dream, I believe that  a pursuit of a Ph.D. degree is the indispensable way to deepen my knowledge and understanding of the AI world.
Your university is ideal for me. It has a distinguished educational and research reputation. But what has impressed me most is that many of your on-going projects are similar to mine. If admitted to your program, I will be able to make full use of my research experience to finish this degree. My solid background in Artificial Intelligence (especially machine learning) and algorithm design and analysis will help me more in the following topics, both theoretically and experimentally:
Artificial Neural Network.
Multi-Agent Learning.
Computer Graphics Algorithm
I am confident that my diverse research experience, firm commitment to Artificial Intelligence and algorithm have qualified me to undertake different challenges. I look forward to fulfilling my dream by working efficiently and  hard at your esteemed institute.

 3   Personal Statement  
Witnessing my Dad successfully fight to survive cancer, I learned to appreciate life and the opportunities it presents. I was in my first year of high school and could not have cared less about homework and exams. Spending most of my time hanging out with friends on the street, I seldom opened my books. It came as no surprise when I failed all courses except Chinese and English. I remember it was on the day I boasted about getting “A”s in these two courses without even trying that my Dad told me he had cancer. He was calm and serious. I was speechless, ashamed, and desperate. All my life, my Dad had spoiled me and built a secure home for our family. I never worried about anything. As my sad and panicked tears poured down my cheeks, my Dad said to me, “XXX, it is time that you grow up, be strong, and make good use of yourself.”
Saying good-bye to my relaxed life style was not easy, but it became easier every time Dad recounted a story of my childhood when I visited him at the hospital. His favorite story was the fishing trip we took together when I was four. He recalled all my funny questions and the eccentric “suggestions” I gave on how to catch a big fish. “You were so curious and bright!” “I knew then you were a different child.” “Just be yourself, take your time, and you will catch up”, he said in a weak voice but with much confidence. I was so determined to prove Dad is right that I concentrated on my studies completely and rose to No.1 in my class the following semester. Dad likes to attribute his gradual recovery to my academic progress. Although I know his doctors and his optimistic attitude made the real difference, I am proud that he thinks that way and most of all, I feel so fortunate that my own personal “cancer” was also cured by this experience.  
The following year, I scored high in the most competitive National College Entrance Examination and got accepted to XXX University. I couldn’t stop my tears when I dashed to my Dad and broke the good news to him! In his firm warm arms, I vowed to myself that never again in my life would I waste time. I also vowed to treasure each opportunity trusted on me and give all I have to achieve my best! During the four years in college, majoring in Corrosion and Protection of Metals in the Mechanical Department, I consistently worked hard and achieved great academic success. Applying the theoretical knowledge I learned from the various courses I had taken, I successfully completed my thesis research XXXXXX successfully in 6 months. Besides maintaining good academic standing, I also participated in many social activities. I was one of the founding organizers of the Student Union and organized many large-scale parties and activities. Due to my presentation and leadership in the Community Volunteers’ Association, I was awarded the “Honor Citizenship” by the local government. I was indeed proud when my advisor made the remark at the graduation ceremony that he was proud to have worked with a diligent, responsible, charming, and influential student like me. After graduation, I worked in SSS at the Painting Department of JJJ Co., Ltd, the major ship manufacturer in China. During this period, I had a chance to apply my knowledge learned from the university. In three years, I worked very hard and completed two research projects perfectly. “Her passion for the job is incredible. She puts all her heart and energy into the job and can’t bear any mistakes,” my colleague would say when introducing me. In the three years that I have worked for this company, I have kept careful and responsible habits while painting the surfaces of ships. Generally, it is not considered suitable for women to work at the worksite and I am the only female in my painting department. However, to gain important information, I went to the worksite by myself. During my second year at the company, I began to design the painting technology and process and I was put in charge of painting two self-unloading ten-thousand-ton ships coded H2227 and H2228 when they were first made by my company. Despite the construction complexities and execution difficulties, I worked out an effective painting process after I analyzing the blueprints and making process recommendations to the experienced engineers. This painting process set an example for the later work that was similar in nature. I have also served as an assistant to our principal engineer who studied the painting on oil tankers that work under special circumstances such as icy conditions.
As my work and research becomes more complicated, I am finding that my knowledge is very limited. For example, while the clean-up of rust is the most tiring and dirty process, it is necessary to guarantee the painting quality. Until now, no effective and economical technology has been introduced to improve this process. Does the kind of paint exist that does not demand a clean surface? Dirt-proof paint is harmful to marine organisms and pollutes the sea. Is there a kind of paint that does not pollute the sea? In addition, how to improve the cohesion of the paint layers; how to improve the corrosion resistance, durability and shock resistance of paint film; how to improve the corrosion resistance of the material in order to reduce the large quantity of paint used in painting? All these questions drive me to enrich myself and do more research in order to find answers. I successfully passed the GRE and TOEFL in spite of my busy schedule and have decided to apply to study for a Master’s Degree in Chemical Engineering in your engineering school. My major interests in the future reside in the following areas: the properties of new materials, corrosion and protection of materials, and environmentally friendly chemical technology. If you feel that any other areas are more suitable for me, your comments and suggestions will be highly appreciated. I am attracted to the history and reputation of your graduate engineering school and look forward to studying under the prominent professors in your program while using the advanced facilities in your department to conduct worthy research on ship surface painting. After gaining substantial experience, I plan to return to China in order to devote myself to the promotion of the development of chemical technology in China.

 4)        Personal Statement
I have immense love and admiration for my illiterate farmer parents. They don’t speak fancy words, yet they taught me to be humble, true, and kind to myself and other people; they do not make much money, yet they always made sure I had adequate money for tuition and books; they had great expectations for me, yet they never forced anything on me. I began to appreciate my parents’ unconditional love and sacrifice when I was just a little boy. Ever since I discovered that earning good grades made my parents happy, I have studied diligently at school to be the best student I can be. My childhood dream was simple and clear: to become a highly educated person. As I am writing this personal statement, I realize that, in some sense, I have already achieved my childhood goal. I will soon graduate from XXX University, one of China’ top universities known as the cradle of engineers, as an exceptional student honored with numerous awards. On the other hand, I realize that I am just getting closer to my goal. I still have lot to learn. For this reason, I am applying for the acceptance to your graduate program, a vital step in reaching my ultimate goal.
I first became interested in electronics when I was in middle school and received a cassette player from my physics teacher on my fifteenth birthday. Curious about the circuit diagram printed on the cassette’s introduction booklet, I asked my teacher how it worked. Although he explained to me patiently, I could not quite grasp its wonder at the time but I was determined to do so. In high school, I read some illuminative books about electronics recommended by my physics teacher. In my spare time, I made electronics devices such as doorbells. When my experiments finally worked, I was fascinated. I found that being able to put what I have learned into practice is a great pleasure. Later, at our school’s Science and Technology Fair, my paper “A New Way to Measure Resistance” won the first prize. I performed excellently in the National University Entrance Examinations and without any hesitation, I chose to study Electronics Engineering at XXX University.
While studying at XXX, driven by my intense interest and clear goals, I have worked very hard and steadily remained in the top 5% of my class, with an overall GPA of 3.56 in the highly competitive Electronics Engineering Department, which is comprised of top students from all over China. I am particularly good at mathematics and physics. My excellent academic record has earned me many honors and scholarships. Eager to learn more than what is taught in class, I often read books and journals concerning the cutting-edge electronics technology in order to broaden my scope. I am also enthusiastic about the lectures given by prominent professors, from whom I can absorb innovative ideas. XXX places great emphasis on undergraduate students’ independent research ability. Under these circumstances, I have not only developed meticulous research habits but have also mastered scientific analytic methods. When still a junior student, I was selected to join the state laboratory of fine functional electronic materials and devices, led by a prestigious professor EEE, a member of the Chinese Academy of Sciences. There, I had the precious opportunity to work on characterization of semiconductors such as GBT. During my internship, I also obtained first-hand experiment experience from working in several large IC manufacture companies and institutions including National Research Institute of Electricity and Electronics. I feel that I have benefited greatly from these experiences. I not only work hard academically but also participate in various activities enthusiastically. I am the leader of XXX University’s Delegation, taking part in “Protecting the Wetlands Action”, a campaign launched and sponsored by World Fund For Nature (WWF) and reported by China Youth Daily. Our team’s innovative prospectus about investigating the living environment of Red Crowned Crane, a precious and endangered bird with only 3000 left on earth, in one of world’s biggest Red Crowned Crane’s gathering place Yancheng, Jiangsu province, earned us 5000 RMB worth of financial support given by WWF. Only nine other teams in China received this grant in 2001. Our month-long investigation proved to be a great success. I was also the Office Director of the Student Union. I once tactfully convinced the Ever Bright Bank to sponsor our National Day Party with the agreement to offer them the naming rights if they solved our financial problems. During my tenancy, I also managed and organized many instructive and popular activities such as Do It Yourself (DIY) and Voluntary Blood Donation. Due to my consistent hardworking attitude and conspicuous work achievement, I was awarded “Excellent Office Director of the Student’s Union”- an honor given to only a few students each year. All of these unique social experiences have greatly enhanced my leadership and communication abilities.
In recognizing my outstanding academic record, excellent research ability and prominent performance in social work, my soon-to-be Alma Mater has offered me to exempt me from the entrance examination if I choose to enter graduate studies at this school, a privilege given to only top students. However, I turned down this offer because I long to study abroad. One reason is that, due to the low budget of Chinese education funds, some lab experiments in Chinese universities are so out-of-date that conducting certain demanding experiments is difficult or even impossible. Another reason is that I realize, frankly speaking, that China’s electronic industry is far behind the times. During my internship in YYY company, whose calculate amplifier was the first in China and was used on China’s first man made Satellite OrientalRed, I found all so-called advanced equipment in their streamline are bought secondhand from American companies. To my astonishment, one of these “advanced” systems used to control the oxidation (a vital process in manufacturing IC) is still using 14-inch software that is too outdated to find on the market. Since America is in the leading position in electronic industry and education, it is an ideal place for me to take full advantage of my potential to grasp information that is at the forefront of technology. Furthermore, the culture in America is so diverse that I feel I will be able to acquire broader perspectives and more profound insights.
My research interest is semiconductor device/physics, as well as Semiconductor Processing and Technology. In my mind, devices are the most basic components of circuits. To achieve a deeper understanding of devices is very helpful to the design and fabrication of IC. The success we had on diode and transistors is revolutionary in the history of electronics. I would also like to make great achievements on this field. Among hundreds of graduate schools in the United States, I consider your university the best and most suitable for me. Your department has up-to-date research facilities and impressive research funds, which shows your program’s leading position in the US. Under your esteemed faculty’s guidance, together with my solid academic background, I’ m sure my childhood dream will become a reality.
After my graduation, I will devote myself to the development of China’s electronic industry. I not only want to be a man of success but also to be a man of value.

5)       Personal Statement
I wish to pursue a Ph.D. degree in your University in order to extend my academic and career development. Holding a Bachelor’s degree in Electrical Engineering, I have worked in an electronics company as an experienced electrical engineer for two years. I think it is the right time that I go back to school and study in a doctoral program of EE. A Ph.D. in EE will give me invaluable knowledge for my career by researching cutting-edge hardware product design and development. Your university provides the ideal place for me to do this research. I am confident that my education and research experience, from both university laboratories and industrial companies, prove my commitment to the EE field. I also believe that the experienced professors and the advanced academic environment of your program will help me achieve my professional goals.
I have been interested in electronics since my childhood. Electronics such as the radio and television were very magical things to me. My parents’ appliances were seldom in good condition because I always took them apart in order to discover the mysteries behind their magic. I always saved my pocket money to buy reference books on electronics and electronic devices. Even before entering college, I designed some simple circuits and fixed defective home appliances, giving me my first practical experience. Electronics fascinated me and I was filled with strong desire to design and improve electronic devices. My great interest in EE was cultivated at that time and from there my entire career path was defined. After graduating from high school, I was admitted into CCC University after being exempted from the entrance examination. Based on my interests, I naturally selected EE as my major. Four years of comprehensive training in the EE department provided me excellent mastery of electronics theories and practices. I excelled in all courses including the most difficult ones: Basics of Analog Electronic Techniques (93/100), Basics of Digital Electronic Techniques (99/100), Curricular Project of Electronic Technique (95/100), Signal and System (96/100) and Electric Power Electronics (80/100). Furthermore, I actively involved myself in practical research and laboratory work at the university so that I could integrate textbook knowledge with hands-on working experience. My was able to enrich my knowledge exponentially through these kinds of experiences.
I began laboratory work relatively early compared to most of my peers. During my junior year at CCC University, I joined the Electronics Lab of the EE Department and had the opportunity to conduct research in the field of Embedded System Design. This was my first, and most important, step into a professional research career. During the process, I got chance to use the Microchip Technology Inc.’s newest generation of the PICmicro microcontroller (MCU) to design my embedded system. I selected the best microcontroller for my application and became familiar with the MPLAB Integrated Development Environment (IDE) software and many others including Assembly Language and C Language based on the PICmicro microcontroller (MCU) and PC (personal computer), Protel98 in schematic and PCB circuit board design. I often became so absorbed in this interesting and original research that I would work on the programs and electronic circuits in the laboratory all day and all night. Even when I went back to my apartment, the problems were still on my mind.
In July 1999, along with two other team members, I was selected by our university to attend the National Undergraduate Electronics Design Contest. In the following three months, we completely devoted ourselves to prepare for the competition that was to be held in September 1999. Our task was to use the microprocessor provided by the Microchip Technology Inc. to establish an Intelligent Phonetic System. The main functions of this system were to sample, compress, store and play back voice signals. Since the original voice signals transmitting through the microphone were mixed with other noises, a noise canceller was necessary. After being filtered through the noise canceller, the voice signals would then be amplified before entering into the A/D converter. Because of memory limitations, the digital signals first had to be compressed using certain algorithms. Later, the stored digital data needed to be converted back into analog voice signals. The whole process was controlled by the microprocessor. My job was to build the hardware, including the analog and the digital circuits for the system; the other two students were in charge of the software development. We had to cooperate efficiently to accomplish the task within the allotted time. Our hard work paid off. We won the first prize in the competition after three months’ collective effort. This experience was a milestone in my research career. I not only obtained invaluable research experience, but also understood the importance of cooperation. It was after this project that I made my finial decision to take the research career path.
After graduation, I joined an electronics company as a hardware designer. At the time, I was so exited about the fact that my childhood dream had finally come true. Working for this company, I learned many new skills. For instance, I learned programmable logic, FPGAs (Field Programmable Gate Arrays) and the hardware language VHDL on Xilinx Platform. I also proved to my colleagues and the project manager that I was an excellent hardware developer. The ASIC (Application Specific Integrated Circuit) that I designed has been widely used on our company’s products. For example, it was used in the terminal computer as the POS (Point Of Sale) for banks and supermarkets. During this period, I gained valuable practical research experience and learned to take advantage of high-tech media to effectively communicate and work with others. I find the most efficient method of learning is through interacting with people who share common interests and concerns. I often use the Internet to discuss problems with other electrical engineers. I also frequently browse some important electronics companies’ web sites to check if there are any new tools or services that might be helpful for my work. This approach has broadened my horizons and improved my flexibility. The Internet has become a creative source for me to solve problems. However, it is also during this time while working in this company, I have begun to realize that I am still way behind many other engineers, especially those abroad. China’s electronics industry has a long way to go before catching up with that of the US. I believe that the 21st century is a critical time for the rapid development of electronics technology and I have set my long-term career goal to become an expert who can influence, or perhaps even lead, this revolution. Therefore, it is vital that I pursue higher education through further systematic training in the field of Electronics Engineering. I believe that attaining a Ph.D. Degree from your university will be the cornerstone on which to achieve my goals. I believe that this degree will provide the academic training, experiences and skills needed to achieve my success in the EE domain. I am confident that my educational background, research experience, passion toward this field, and dedication has well prepared me for graduate study. I am looking forward to sharing my knowledge and working with you and my prospective classmates in the near future.
