The use of smart antennas to increase mobile communications channels has re-ignited research and development in the field. Practicing engineers are eager to discover more about this subject, and need a comprehensive book that can provide a learning platform and prevent the loss of time spent on searches through journal literature.Smart Antennas examines nearly all aspects of array signal processing and presents them in a logical manner. It delivers a detailed treatment of antenna array processing schemes, adaptive algorithms to adjust weighting, direction of arrival (DOA) estimation methods, diversity-combining methods that combat fading and reduce errors.The book introduces the various processor structures suitable for the narrowband field, examining the behavior of both element space and beamspace processors. It then explores adaptive processing, focusing on the simple matrix inversion algorithm, constrained least mean squares (LMS), the neural network approach, and more. The text also describes smart antennas that are suitable for broadband signals, and presents analyses and techniques suitable for correlated fields in narrowband and broadband signals.This volume supplements its content with extensive references, enabling you to further investigate smart antenna array schemes and application.

"Жратва" — книга-протест "человека из толпы" против бесконечных социальных экспериментов и опытов, представляющих собой неспровоцированное посягательство на достоинство человека и качество жизни. Это — набор историй и рецептов, по большей части смешных, о том, что и как можно есть. Все эти байки разделены на три части: "Рыба", "Мясо", "Ни рыба, ни мясо". Текст написан профессиональным ученым, но непрофессионально и неровно: то изысканно-изящные ресторанные пассажи, то грубый общепитовский сарказм, то добродушный домашний юмор — жизнь разнообразна и, по счастью, нелепа, что помогает нам хоть чему-нибудь научиться и хоть что-нибудь понять. Книга рассчитана на узкий круг читателей, не утерявших аппетита и вкуса к жизни. Широкие слои вегетарианцев, лечебно голодающих, профессионалов жратвы на раутах и официальных обедах, работников частного и особенно государственного сектора общественного питания, а также врачей-диетологов просят не беспокоиться.

This encyclopedia set, part of the Macmillan Science Library series, is designed to accommodate middle-school students through college undergraduates. The work contains approximately 300 signed entries on a variety of topics relating to animal science, including animal development, functions, behavior, ecology, and evolution. The connection between animals and humans is also explored in entries such as Animal testing, Apiculture, and Domestic animals. Also included are biographies of noted scientists who have made "significant contributions" to the field (for example, Henry Walter Bates, Rachel Carson, Gregor Mendel) as well as introductions to career opportunities in the related disciplines. Articles appear in alphabetical order and range in length from several paragraphs to several pages. All are accompanied by see also references and further reading suggestions (including Web sites). Each volume begins with a complete table of contents, a geological time scale, five- and six-kingdom classification comparisons, a phylogenetic tree of life, and a chart of measurements, abbreviations, and conversions. Each concludes with a topic outline, an index (volume 4 contains a cumulative index), and a 600-plus-word glossary.

After the Encyclopedia of Sociology had been in print only three years, we began to receive inquiries about when there would be a revised edition. This was surprising given that the Encyclopedia was so well received, that its distribution had been much broader than even optimistic supporters of the project had anticipated, and that the articles were largely broad reviews and summaries of areas of knowledge in sociology. However, some areas in sociology changed quickly during the last decade as we approached the Millennium so that interest in a recapitulation and updating did not seem inappropriate. In addition, the social sciences appear to have softened their borders, and thus we realized that a substantial and thoughtful addition of titles would add breadth and depth to the Encyclopedia.
