This course covers the signal representation/analysis, especially how to represent the complex signals in simple format either in time or frequency domain. Based on that, it also covers how signals behave after passing through various linear, time-invariant systems. It consists of following individual yet highly related sessions including Introduction, time-domain analysis on the linear, time-invariant systems, signal representation in frequency domain (Fourier analysis & Fourier transform), Laplace Transform, Discrete time-domain signals, Z-Transform, Discrete & Fast Fourier transform, the state space analysis of the linear systems, and etc. This course focuses on the basic theory and analytical method from time-domain to transform domain, from continuous to discrete, from the description of single-input-single-output to the state variables. It will lay down a solid foundation for the further study for courses including Digital Signal Processing, Stochastic Process, Communication Circuit, Principle of Communication. The requisite courses include calculus, linear algebra, complex variable functions, principles of electric circuits.

This course will lead students to practice the content production and operation of all categories, all processes and all media. Students participate in the actual work of the project, master the ability of graphic writing, video production and podcast production in a real all-media environment, participate in large-scale live broadcasting and large-scale activities, carry out actual operation under the guidance of teachers, and ride the waves in the ocean of digital media. The content involved includes but is not limited to interviewing and photographing senior professors, new scholars, outstanding students and alumni, reporting campus scenery, interesting courses and lectures, campus sports activities, cultural activities, community activities, exhibition performances and so on.

Among the many fields of modern logic research, modal logic has been deeply applied in many fields from humanities to software design because of its good balance between expressiveness and complexity. In this course, the concepts and methods of modal logic will be introduced with its application in modeling time, knowledge, necessity, and social behavior. In this way, students will be brought into an environment similar to actual research and experience the interaction between different concepts and needs in theory and practice. This course will guide students to become familiar with classic textbooks, manuals, and important articles, and enable students to explore and learn deeper content on their own when they have further interest. 

The course will explore the history of the Modern Movement from the 19th century onward, including its gestation, maturation, decline, and the subsequent evolution of foreign architecture. This course not only helps students understand the roots and processes of the dramatic architectural transformations over the past centuries but also provides intellectual nourishment for their current design training.

This course is designed for students pursuing careers in fixed-income securities trading and modeling, as well as those interested in academic or regulatory research in fixed-income markets and credit risk management. It provides a comprehensive overview of China’s fixed-income markets and policy interest rate system. Students will learn key modeling techniques to price and analyze various fixed-income instruments, including default-free bonds, corporate bonds, and interest-rate derivatives. While the topics are inherently quantitative, the course emphasizes practical applications over purely technical aspects. The goal is to equip students with fundamental knowledge, trading strategies, and hands-on programming skills.

This course systematically introduces the core issues and cutting-edge research problems of international sinology. Through case analysis and in-depth theoretical discussion, this course teaches the academic methods and theoretical framework of international sinology and introduces historical methods on society, material, thought, literature, and multidisciplinary and cross-cultural comparison. The main content includes but is not limited to research topics such as ancient history, literature, anthropology, and ancient China from a cross-cultural perspective under international sinology.

This course focuses on the principles and applications of welding and cutting technology, as well as the latest developments and application status of this technology at home and abroad. It aims to enable students to not only master the basic knowledge of modern welding and cutting and related technologies, but also understand the forefront of discipline development, grasp the development trend of the discipline, broaden their horizons, and activate academic thinking, so as to improve the ability of graduate students to carry out innovative research. The main contents include: introduction to different welding methods such as gas welding, arc welding, resistance welding, pressure welding, high-energy beam welding, as well as cutting methods, welding automation, welding sensors, welding forming methods, etc., focusing on their latest developments and applications.

The aim of this course is to familiarize the student with some of the cornerstones of modern logic: the completeness of first-order logic, Gödel’s incompleteness theorems, and Church and Turing’s results on undecidability. Proofs of these results are presented in some detail, including quick introduc)ons to basic model theory, primi)ve recursive and recursive func)ons, Peano arithme)c, and the method of ‘arithme)za)on’ of metalogic, on which the incompleteness and undecidability results rely. The philosophical implica)ons of these results, and the techniques used to prove them, are also discussed, and the intui)ve ideas behind the technical construc)ons are emphasized.

This course explains the emergence, development, and design of social insurance systems from the industrial revolution to the modern society. The course discusses the insurance protection needs of the society as a whole, discussing many benefit programs designed to reduce economic uncertainty, including social security, health insurance, workers' compensation, unemployment compensation, and disability insurance. We discuss principles, features, and policy issues related to social insurance and public assistance programs.

In this subject, students are introduced to gene structure and function, DNA replication, transcription and translation; molecular biology; protein structure and its relationship to protein function.
