As the physical quality of life improves in our increasingly global and technologically focused world, it is particularly important to focus on psychology. In fact, psychology is one of the most popular subjects studied in universities by students across the globe, and there is an increasing interest in studying this fascinating - and constantly changing - field.

This course will cover a wide range of topics from the field of psychology to provide a comprehensive introduction to the subject. Course lessons will focus on consciousness, sensation, perception, learning, memory, thinking, emotion, evolution, motivation, personality, social psychology, and happiness. In every lesson, we use empirical studies of psychology and classical theoretical perspectives as examples, concluding the course with the relatively new perspective of positive psychology. In this course, you will gain an understanding of psychological modes of thought and master the basic methods of psychological research, while freeing yourself of psychological misconceptions and misunderstandings.

在人们物质生活飞速发展的今天，关注心理学显得尤为重要。在美国大学，心理学是学生人数最多且最受欢迎的学科之一。本课程分为13章，分别阐述绪论、意识、感觉、知觉、学习、记忆、思维、情感、进化、动机、人格、社会以及幸福问题。在每一章中，都会以心理学的实证研究作为例证，以经典理论观点作为主导，以积极正面的心理学研究为方向，让学生掌握心理学的基本内容和前沿动态，了解心理学的思考方式，去除对心理学的疑惑与误解，掌握基本的心理学研究方法。    

Despite the large volume of data mining papers and tutorials available on the web, aspiring data scientists find it surprisingly difficult to locate an overview that blends clarity, technical depth and breadth with enough amusement to make big data analytics engaging. This course does just that.

Each module starts with an interesting real-world example that gives rise to the specific research question of interest.

Students are then presented with a general idea of how to tackle this problem along with some intuitive and straightforward approaches.

Finally, a number of representative algorithms are introduced along with concrete examples that show how they function in practice.

While theoretical analysis sometimes overcomplicates things for students, here it’s applied to help them better understand the key features of the techniques.

本课程完整覆盖数据挖掘领域的各项核心技术，包括数据预处理、分类、聚类、回归、关联、推荐、集成学习、进化计算等。强调在知识的广度、深度和趣味性之间寻找最佳平衡点，在生动幽默中讲述数据挖掘的核心思想、关键技术以及一些在其它相关课程和教科书中少有涉及的重要知识点。本课程适合对大数据和数据科学感兴趣的各专业学生以及工程技术人员学习，不追求纯粹的理论推导，而是把理论与实践有机结合，让学生学到活的知识、有用的知识和真正属于自己的知识，特别是数据分析领域的研究方法和思维方式。

计算机是现代社会中用于解决问题的重要工具。利用计算机解决实际问题需要将问题抽象，并对数据进行操作，最后通过计算机程序求解问题。而本门课程主要内容就是对以上内容进行研究。

图灵奖获得者N.Wirth写了一本经典著作“程序=算法+数据结构”。数据结构，是抽象的表示数据的方式；算法，则是计算的一系列有效、通用的步骤。算法与数据结构是程序设计中相辅相成的两个方面。

我 们会围绕着“算法+数据结构=程序”的思路，以问题求解为导向进行学习。希望能够帮助大家提高理论、抽象、设计的能力。在扎实的经典理论基础上，运用问题 抽象、数据抽象、算法抽象来分析问题，应用适当的数据结构和算法来设计和实现相应的程序。通过课程学习，大家的抽象思维能力、问题求解能力将得到较大提 升，编程能力和代码质量会有质的飞跃！

在求解实际问题方面，我们会学习到通过权衡时空和其他资源开销，利用数据结构来组织数据、设计高效的算法、完成高质量的程序以满足错综复杂的实际应用需要。

此外，课程所学到的内容会被利用到计算机科学后续的各个课程中，如操作系统、软件工程、数据库概论、编译技术、计算机图形学、人机交互等。希望可以为大家将来从事计算机相关的学习、研究和开发工作打下扎实的基础。

本课程采用张铭主编的国家“十一五”规划教材《数据结构与算法》（高等教育出版社）。适合计算机以及相关理工专业的大二本科生学习，需要先修过计算概论等课程，具有结构化和面向对象的程序设计基础。

课程主要包括的内容有：线性表，栈与队列，字符串，二叉树，树，图，排序（内排序，外排序），检索，索引，高级数据结构、以及数据结构应用。课程持续16周（分为两个session，每个8周），学习者每周在本课程上需要投入4－8小时。

Computers are an important tool for problem solving and are deeply involved in modern life. Computers perform operations on data. What is the logical relationship among data? How is data stored in computers? What algorithms are required to solve particular problems? These are the questions that will be answered in “Data Structures and Algorithms,” an important core course in Computer Science. The course also introduces students to fundamental data structures and classical algorithms used in more specialized courses, including Operating Systems, Software Engineering, Database Systems, Compiler Principles, Computer Graphics and Human Computer Interaction.

Niklaus Wirth described the important and indivisible link between algorithms and data structure in his book, Algorithms + Data Structures = Programs.

The course will build on Wirth’s ideas as it helps students improve their knowledge of theory and their ability to think abstractly to solve problems. Building on a solid theoretical foundation, students will analyze problems using data and algorithm abstraction. Students will learn how to organize data efficiently and make tradeoffs between space and time complexity, design efficient and effective algorithms, and implement high quality programs to solve complex real-world problems. After studying this course, students will be well prepared for further study and research in engineering and other computer-related areas.

This is an intermediate-level course appropriate for sophomore students majoring in computer science or other science/engineering disciplines. Students should have learned "introduction to computing", with the knowledge of structured and object-oriented programming.

This course is presented in two eight-week sessions.

Students who score 60% or higher will receive an Honor Code Certificate.

The Autumn 2014 Sessions of this course are supported by Google.

Finite Element Method (FEM) is a powerful tool. FEM is an effective numerical technique for partial differential equations (PDEs) in engineering. The fact that modern engineers can obtain detailed information for structural, thermal, electromagnetic problems with virtual experiments largely gives credit to FEM. The finite element method provides infinite possibilities for engineering, and this course provides a detailed introduction of FEM and its applications in engineering and beyond.

This course is divided into 15 lessons, which introduce basic equations of mechanics, mathematical principles of FEM, realizations in both discrete and continuum structures, various applications in engineering and skills at modeling with FEM software. Examples are demonstrated with MATLAB and ANSYS.

有限元方法(finite element method)：基于数学力学原理，采用计算机信息化分析手段，完整获取复杂工程问题及科学研究中的定量化结果，也被称为一种基于计算机信息化处理的“虚拟实验”，在数学上它是求取复杂微分方程近似解的有效工具，是现代仿真技术的重要基础原理。有限元分析的力学基础是弹性力学，方程求解的数学原理是加权残值法和泛函极值原理，实现的方法是数值化离散技术，最终的载体是有限元分析软件。有限元方法已成为机械、航空航天、土木、力学等专业学生的必备知识。

1999年欧元问世引起世人瞩目，人们在关注它给欧洲经济、世界经济和国际货币体系带来何种影响的同时，也必然要探究欧元产生的背景。实际上，欧元的诞生不是偶然的，它是欧洲经济一体化发展的必然结果。

欧盟作为当今世界上最大的区域性贸易集团，是区域经济一体化的先驱。在世界经济全球化、区域经济一体化的今天，特别是2010年1月1日中国—东盟自由贸易区全面启动的情况下，我们研究和考察欧盟在经济一体化进程中采取的政策和措施不仅十分必要，而且也非常具有现实意义。

今年是欧盟诞生60周年。在欧洲一体化走过的历程中，我们看到其中经历的风雨挫折和不懈与成就。这几年，欧债危机、难民潮和英国脱欧等使欧盟成为世界的焦点。欧盟和其倡导的欧洲一体化前景如何？相信学习本课程后，你会对此问题有比较客观的见解。

本课程通过老师讲解，结合观看课件、现实案例、生动视频，让同学们对欧洲经济一体化的背景、它所实施的相关政策对欧盟及其成员国经济发展的影响有一个比较全面的了解，分析欧盟实施的一些相关政策的成效，并在此基础上探讨其对我国的启示及借鉴意义。

每个主题由十余组对话和小组讨论，外籍老师的中西方文化差异介绍，中国老师的重点词汇、句型讲解，听力理解练习和口语测试构成。通过学习和练习，你将可以和讲英语的朋友们自如地交谈、讨论与主题相关的任何问题。本课程的学习方法有很多。英语学习者可以在反复地听和跟读对话的过程中，不断积累语言素材，和你身边的朋友或同课程的学习者进行对话练习；英语教师可以选用本课程中适合的主题，组织学生进行听说训练，组织高效课堂。也许你不能理解每段对话的全部内容，只需听懂大意，随着课程的进展，你听懂的内容会越来越多。让我们一起实现一次英语听说的飞跃吧。
