• ### Báo cáo khoa học: "Introduction to Computational Advertising"

Web advertising is the primary driving force behind many Web activities, including Internet search as well as publishing of online content by third-party providers. Even though the notion of online advertising barely existed a decade ago, the topic is so complex that it attracts attention of a variety of established scientiﬁc disciplines, including computational linguistics, computer science, economics, psychology, and sociology, to name but a few.

• ### Lecture Introduction to Computers: Chapter 13A - Peter Norton's

Chapter 13A - Creating computer programs. This chapter define the term computer program, describe the use of flowcharts and pseudocode in programming, identify two ways in which a program can work toward a solution, differentiate the two main approaches to computer programming, list and describe three elements of object-oriented programming.

• ### Fundamentals of Computer Science using Java

This book is an introduction to computer science. Computer science is the study of computer hardware, algorithms, and data structures and how they fit together to provide information systems. Each of these topics can be studied at various levels. For example, physicists study the properties of matter that allow hardware components to be designed, electrical engineers study how the components can be combined to produce circuits, and computer engineers study how circuits can be combined to produce computers.

• ### An Introduction to Computational Physics Second Edition

.An Introduction to Computational Physics Numerical simulation is now an integrated part of science and technology. Now in its second edition, this comprehensive textbook provides an introduction to the basic methods of computational physics, as well as an overview of recent progress in several areas of scientiﬁc computing. The author presents many step-by-step examples, including program listings in JavaTM , of practical numerical methods from modern physics and areas in which computational physics has made signiﬁcant progress in the last decade.
