最新中文美国研究生留学个人陈述范文

中美网美国留学  www.usaer.net  2015-03-18    编辑: usaedit1

编者按:远赴美国研究生留学的学生,应该如何准备书写研究生留学个人陈述呢?美国研究生留学个人陈述,简而言之就是ps,就是Personal Statement或Statement of Purpose的缩写。

Pocketed with this passion and thinking, I tasted to use mathematical modeling into practice and solve the practical problems by attending the National College Mathematical Modeling Contest with the other two schoolmates on behalf of our college. It required us to evaluate the water quality of Changjiang River according to the data, through which we had to analyze the water pollution in every region and predict the trend of it in the future. Finally we had to bring out the plan against it. It was really a challenge for us towards flood of data and estimations as long as 17 pages.

We tried almost a whole day only to filter those data and take the evaluations into comprehensive account. Pulling down various models we had built before, we were so defeated that we wanted to give up many times. However, we finally found the satisfactory model thanks to our encouragement to each other which armed us with full strength to go further.We managed to evaluate the water quality by Composite index model, which could not only represent the evaluation factors, but also reflect the main impacts of the contaminations to the water pollution.

We predicted the future water pollution through multiple linear regressions fitting and brought out the plan against it by building linear optimization model. Finally, we got the second prize in Beijing for our thesis. Three days’ and nights’ modeling experience had cooled our passion and gave us even more calm thinking instead. The creation of the mathematical modeling, along with the successful solution to the problems through it lied on the solid mathematics foundation, strong modeling ability, accumulation of the knowledge on different fields, unique creative ideas and creativity.

参加数学建模比赛的经历更加激发起我的学习兴趣,使我在学习数学理论的同时更加注重它们的应用性。除此之外,我抓住一切可能的机会再次参加实际的数学建模。大三的上学期,我有幸参加了为期3天的电工数学建模实习:给某大型运动会比赛项目排序。由于对图论知识很熟悉,我很快将问题转化为寻找最佳Hamilton回路。

接近87亿种不同的排序的数据量,比上次的全国数模竞赛更大,我的算法运行时间相当长而且运行的结果也很不理想。这种情况的发生不仅仅没有打消我的积极性,反而使我的情绪高涨,这是人生中难得的自我考验,自我提高的机会!通过查询资料改用遗传算法,运行时间和结果都大大提高。最后成功地完成这次实习.这次实习给我的感触很大,一个数学模型是否能够完美地解决实际问题还要考虑其运算成本,实际问题不仅需要一个成功的模型还需要一个快速有效的算法。

The experience from this contest further aroused my interest in mathematics. I began to pay more attention to its application as well as learning the theories. In addition, I tried to catch every opportunity to take part in the practical mathematical modeling. My efforts finally rewarded when I was in the first term as a junior. I had a chance to participate in the 3-day electrician mathematical modeling practice-----classifying the sports programs for a big sports meeting. Being familiar with the Graph Theory, I immediately found the way to solve the problems by seeking the best Hamilton circuit line.

Facing the nearly 8.7 billion data files with different orders much more than that on the National Mathematical Modeling Contest, I spent a long time on Algorithm without any perfect result. I wasn’t defeated towards this case, but so excited instead that I could have such a chance to challenge and improve myself. Looking up dozens of files, I finally made a perfect end of the practice by using the Genetic Algorithm into full account. It needs both a successful model and an effective arithmetic to solve these problems. , which largely shortened the operation time and improved the operation result. I learnt a lot from this practice. I came to know that to build successful mathematics modeling that can effectively solve the practical problems, we must take the operation cost

电工数模实习结束后,浓厚的学习兴趣和电工数学实习的教训促使我和数学系、计算机系几名同学共同筹划并创建“数学建模沙龙”,将计算机算法和数学模型共同作为沙龙的主题。每周二下午,我们会组织有兴趣的同学一起,以传授经验、分享心得、共同思考、共同讨论的方法学习和交流数学思想和算法。

传统的运输问题、储存问题和新兴的模拟退火算法、蚂蚁算法都曾成为我们的讨论话题。通过这个活动我从数学系和计算机系的同学身上分享了更多的知识,他们的思维方式,处理问题的方法!到目前为止这个活动仍然在进行着,参加的人数也越来越多。带动了学校的一个学习热潮,我为此感到非常的兴奋!

Summarizing my failures in the mathematical modeling electrician practice and proceeding from my interest in this field, I began to think of collaborating on the “Mathematical Modeling Saloon” with several students from mathematics and computer departments, taking the Computer Algorithms and mathematical modeling as the two themes of the book. Every Tuesday afternoon, we would organized those students interested in this field to study and exchange the ideas and arithmetic by imparting experience, sharing what we learnt, pondering together and discussing with each other.

Both the traditional transportation & storage problems and the modern Stimulated Annealing Arithmetic (SAA), Ant Algorithm have ever been the topic of our discussion, from which I have learnt many thinking styles and methods to the problems from the students both in mathematics and computer department. So far, I am excited to see that this activity is still in the wind with more and more participants and it aroused a learning upsurge in our college.

在老师的推荐下,大三暑假,我参加了邢永丽老师的教学改革项目——“提高数学课堂教学质量”的结果分析。04-05年,邢老师在她和其他几个数学老师的任课班级上做了课堂互动的教学实践,其数据大多以调查问卷等文字形式出现。此模型的特点让我马上联想到模糊数学定量分析模型,但敢于尝试新模型的念头让我最后选择了AHP层次分析法。

通过量化数据,应用AHP层次分析法定量分析老师的综合素质、授课技巧等因素在师生互动、提高数学课堂教学质量中所起的作用,得出教师的授课技巧和课堂问题设置在课堂互动中所占分量最重的结论,并和邢老师合作完成《层次分析法在课堂互动教学效果评价中的应用》论文,邢老师和我对论文都非常满意,已向多个期刊投稿并有望发表。

Recommended by my teacher, I have participated in the Teaching Reform Program of Mrs. Xing yongli----the results analysis of “Improving the mathematics teaching quality on class”. Mrs. Xing, along with some other mathematics teachers experienced the class mutual activities in 2004 to 2005 with the character data files in form of paper investigations. For this style of data files, I finally used the Analytic Hierarchy Process (AHP) as a creative challenge instead of the fuzzy mathematical quantitative analysis models, which firstly knocked my mind.

By quantitating data and using the AHP, I succeeded in analyzing how the overall quality of the teachers and their teaching skills work in improving the mathematics teaching quality on class, from which we got the conclusion that the teaching skills and the way to put forward questions on class play the most important role in the class mutual activities. Besides, Mrs. Xing collaborated with me on the thesis named “The Application of Analytic Hierarchy Processinto the Evaluation of Class Mutual Activities”. Both of us were satisfied with this thesis and contributed it to many presses to be published.

和数学建模一样,金融工程的灵魂是创新思维和创造能力,而数学和数学建模知识在金融工程的应用更让我对这门学科充满了兴趣;更重要的是,金融工程技术能给人们的生活、社会的稳定、国家的发展做出重要贡献,我想这个也更加符合我学习数学建模的初衷。

Similar with the mathematical modeling, the soul of the Financial Engineering is also the creativity. Therefore, the perfect application of the mathematics and mathematical modeling into the Financial Engineering once more surged my enthusiasm in this field. Furthermore, the Financial Engineering plays the important part in people’s living, social stability and the national development, which is my original intention to choose this field I think.
