ANALOG AND DIGITAL COMMUNICATIONS

The objective of this book, like its previous edition, is to provide an introduction to the basic principles in analog and digital communications for advanced undergraduates in electrical or computer engineering. The assumed background is circuit analysis, and prior exposure to signals and systems course is helpful. The book can be used as a self-contained textbook or for self-study. Each topic is introduced in a chapter with numerous solved problems. The solved problems constitute an integral part of the text. In this edition, there are two chapters dealing with basic tools. These tools are then applied to next three chapters in analog communication systems, including sampling and digital transmission of analog signal. Probability, random variables, and random processes are introduced in Chapters 6 and 7 and applied to the chapters that follow. Effect of noise in analog communication systems is covered in Chapter 8. Chapter 9 treats the effect of noise in digital communication and the subject of optimum reception. Information theory and source coding is treated in Chapter 10. A distinctive feature of this edition is the new chapter, Chapter 11, on error control coding, including linear block codes, cyclic codes, and convolutional codes.

ELECTRONIC DEVICES AND CIRCUITS

The subject matter of electronics may be divided into two broad categories: the application of physical properties of materials in the development of electronic control devices and the utilization of electronic control devices in circuit applications. The emphasis in this book is on the latter category, beginning with the terminal characteristics of electronic control devices. Other topics are dealt with only as necessary to an understanding of these terminal characteristics. This book is designed to supplement the text for a first course in electronic circuits for engineers. It will also serve as a refresher for those who have previously taken a course in electronic circuits. Engineering students enrolled in a nonmajors’ survey course on electronic circuits will find that portions of Chapters 1 to 7 offer a valuable supplement to their study. Each chapter contains a brief review of pertinent topics along with governing equations and laws, with examples inserted to immediately clarify and emphasize principles as introduced. As in other Schaum’s Outlines, primary emphasis is on the solution of problems; to this end, over 350 solved problems are presented.

Theory and Problems of Astronomy

The purpose of this Outline is to serve as a supplement to a basic astronomy text. Much of the material here is abbreviated, and students should use this book as a guide to the key concepts in modern astronomy, but not as an all-inclusive resource. Topics covered range from planetary astronomy to cosmology, in the modern context. The first chapter covers most of the phsyics required to obtain a basic understanding of astronomical phenomena. The student will most likely come back to this chapter again and again as they progress through the book. The order of the topics has been set by the most common order of these topics in textbooks (near objects to far objects), but many of the chapters are quite independent, with few references to previous chapters, and may be studied out of order.

THEORY AND PROBLEMS OF ACOUSTICS

This book is designed primarily to supplement standard texts in physical or applied acoustic at the senior undergraduate level, based on the belief that numerous solved problems constitute one of the best means for clarifying and fixing in mind basic principles. Moreover, the statements of theory and principle are sufficiently complete that, with proper handling of lecture-problem time, the book could be used as a text. It should be of considerable value to the physics and engineering students who are interested in the science of sound and its applications. The practicing engineers could also make frequent references to the book for its numerical solutions of many realistic problems in the area of sound and vibration.

Scattering Theory: The Quantum Theory on Nonrelativistic Collisions

This book is intended for any student of physics who wants a thorough grounding in the quantum theory of nonrelativistic scattering. It is designed for a reader who is already familiar with the general principles of quantum mechanics (as taught, for example, in the first year graduate course at most American universities) and who has some small acquaintance with scattering theory, as would be acquired in the same first-year course. It is my hope to bring the student of atomic or nuclear physics to the point where he can begin reading the literature and tackling real problems, with a complete grasp of the underlying principles. For the student of high-energy physics I have tried to provide the necessary background for his later study of relativistic problems.

Миллионер без правил. Как разбогатеть в XXI веке

Приводить истории успешных проектов можно очень много, интернет пестрит рассказами миллионах, заработанных разными людьми. В качестве примера очень удачного стартапа мы можем взять всемирно известный проект Стива Джобса. Компания Эпл, занимающая лидирующее место на рынке мобильных девайсов, – тоже стартап.

НИТРОЗОНАФТОЛЛАР АСОСИДАГИ ИММОБИЛЛАНГАН ОРГАНИК РЕАГЕНТЛАР ЁРДАМИДА АТРОФ-МУҲИТ ОБЪЕКТЛАРИДА БАЪЗИ ОҒИР МЕТАЛЛАРНИ СОРБЦИОН- ФОТОМЕТРИК АНИҚЛАШ

Жаҳонда экологик хавфсизликни таъминлаш мақсадида оғир металларни мониторинг қилиш ва аниқлаш усулларини такомиллаштириш борасида изланишлар олиб борилмоқда. Атроф-муҳитнинг турли объектларидаги мис, кобальт ва темир ионларни аниқлашда органик реагентлардан фойдаланилган ҳолда спектроскопик усуллар кенг қўлланилмоқда. Аниқлашнинг мавжуд бўлган методлари металлни ажратиб концентрлаш ва кейинчалик аниқлаш учун кўп вақт сарфланиши билан боғлиқ. Янги реагентларни мақсадли синтези асосида янги сорбцион- спектроскопик усулларини яратилиши, заҳарли металлардан атроф-муҳит объектларининг ифлосланиш даражасининг ошиши, айниқса оғир металларнинг мониторингини олиб боришга катта эътибор қаратиш зарур.

SCATTERING OF ELECTROMAGNETIC WAVES

Electromagnetic wave scattering is an active, interdisciplinary area of research with myriad practical applications in fields ranging from atomic physics to medical imaging to geoscience and remote sensing. In particular, the subject of wave scattering by random discrete scatterers and rough surfaces presents great theoretical challenges due to the large degrees of freedom in these systems and the need to include multiple scattering effects accurately. In the past three decades, considerable theoretical progress has been made in elucidating and understanding the scattering processes involved in such problems. Diagrammatic techniques and effective medium theories remain essential for analytical studies; however, rapid advances in computer technology have opened new doors for researchers with the full power of Monte Carlo simulations in the numerical analysis of random media scattering. Numerical simulations allow us to solve the Maxwell equations exactly without the limitations of analytical approximations, whose regimes of validity are often difficult to assess.
