Bolalar adabiyoti

Har tomonlama barkamol yangi avlodni tarbiyalab voyaga yetkazish davlatimizning bugungi kundagi eng muhim vazifalaridan biridir. Masalaga shu nuqtayi nazardan qaraladigan bo‘lsa, yoshlar ta’lim-tarbiyasida bolalar adabiyoti yetakchi o‘rinda turadi. „Bolalar adabiyoti“ majmuasi hozirgi zamon talablaridan kelib chiqib, pedagogik yo‘nalishdagi kasb-hunar kollejlari uchun chop etilgan „Bolalar adabiyoti“ darsligi asosida tuzilgan. Unda bolalar folklori, hozirgi zamon bolalar adabiyotining paydo bo‘lishi, rivojlanishi, bosib o‘tgan yo‘li atroflicha tahlil qilinadi.

Charming Proofs

The DOLCIANI MATHEMATICAL EXPOSITIONS series of the Mathematical Association of America was established through a generous gift to the Association from Mary P. Dolciani, Professor of Mathematics at Hunter College of the City University of New York. In making the gift, Professor Dolciani, herself an exceptionally talented and successful expositor of mathematics, had the purpose of furthering the ideal of excellence in mathematical exposition. The Association, for its part, was delighted to accept the gracious gesture initiating the revolving fund for this series from one who has served the Association with distinction, both as a member of the Committee on Publications and as a member of the Board of Governors. It was with genuine pleasure that the Board chose to name the series in her honor.

DISCRETE-TIME SIGNAL PROCESSING

This third edition of Discrete-Time Signal Processing is a descendent of our original textbook Digital Signal Processing published in 1975. That very successful text appeared at a time when the field was young and just beginning to develop rapidly. At that time the topic was taught only at the graduate level and at only a very few schools. Our 1975 text was designed for such courses. It is still in print and is still used successfully at a number of schools in the United States and internationally. By the 1980's, the pace of signal processing research, applications and implementation technology made it clear that digital signal processing (DSP) would realize and exceed the potential that had been evident in the 1970's. The burgeoning importance of DSP clearly justified a revision and updating of the original text. In organizing that revision, it was clear that so many changes had occurred both in the field and in the level and style with which the topic was taught, that it was most appropriate to develop a new textbook, strongly based on our original text, while keeping the original text in print. We titled the new book, published in 1989, Discrete-Time Signal Processing to emphasize that most of the DSP theory and design techniques discussed in the text apply to discrete-time systems in general, whether analog or digital.

Convex Analysis and Optimization

This book focuses on the theory of convex sets and functions, and its connections with a number of topics that span a broad range from continuous to discrete optimization. These topics include Lagrange multiplier theory, Lagrangian and conjugate/Fenchel duality, minimax theory, and nondifferentiable optimization. The book evolved from a set of lecture notes for a graduate course at M.I.T. It is widely recognized that, aside from being an eminently useful subject in engineering, operations research, and economics, convexity is an excellent vehicle for assimilating some of the basic concepts of real analysis within an intuitive geometrical setting. Unfortunately, the subject's coverage in academic curricula is scant and incidental. We believe that at least part of the reason is the shortage of textbooks that are suitable for classroom instruction, particularly for nonmathematics majors. We have therefore tried to make convex analysis accessible to a broader audience by emphasizing its geometrical character, while maintaining mathematical rigor. We have included as many insightful illustrations as possible, and we have used geometric visualization as a principal tool for maintaining the students' interest in mathematical proofs.
