Complex environmental problems are often reduced to an inappropriate level of simplicity. While this book does not seek to present a comprehensive scientific and technical coverage of all aspects of the subject matter, it makes the issues, ideas, and language of environmental engineering accessible and understandable to the nontechnical reader.
Improvements introduced in the fourth edition include a complete rewrite of the chapters dealing with risk assessment and ethics, the introduction of new theories of radiation damage, inclusion of environmental disasters like Chernobyl and Bhopal, and general updating of all the content, specifically that on radioactive waste.
Since this book was first published in 1972, several generations of students have become environmentally aware and conscious of their responsibilities to the planet earth. Many of these environmental pioneers are now teaching in colleges and universities, and have in their classes students with the same sense of dedication and resolve that they themselves brought to the discipline. In those days, it was sometimes difficult to explain what indeed environmental science or engineering was, and why the development of these fields was so important to the future of the earth and to human civilization. Today there is no question that the human species has the capability of destroying its collective home, and that we have indeed taken major steps toward doing exactly that. |

The U.S. Army Campaigns of World War II.
World War II was the largest and most violent armed conflict in the history of mankind. However, the half century that now separates us from that conflict has exacted its toll on our collective knowledge. While World War II continues to absorb the interest of military scholars and historians, as well as its veterans, a generation of Americans has grown to maturity largely unaware of the political, social, and military implications of a war that, more than any other, united us as a people with a common purpose. Highly relevant today, World War II has much to teach us, not only about the profession of arms, but also about military preparedness, global strategy, and combined operations in the coalition war against fascism. During the next several years, the U.S. Army will participate in the nation’s 50th anniversary commemoration of World War II. The commemoration will include the publication of various materials to help educate Americans about that war. The works produced will provide great opportunities to learn about and renew pride in an Army that fought so magnificently in what has been called “the mighty endeavor.” World War II was waged on land, on sea, and in the air over several diverse theaters of operation for approximately six years. The following essay is one of a series of campaign studies highlighting those struggles that, with their accompanying suggestions for further reading, are designed to introduce you to one of the Army’s significant military feats from that war. This brochure was prepared in the U.S. Army Center of Military History by Dale Andradé. I hope this absorbing account of that period will enhance your appreciation of American achievements during World War II.

В учебном пособии рассматриваются основы теории вероятностей и понятия статистической проверки гипотез. Обсуждаются теория стационарных случайных процессов, теория марковских цепей и процессов, включая центральную предельную теорему для цепей Маркова и предельный переход от динамической системы к диффузионному процессу. Обобщен опыт различных конкретных применений теории вероятностей. Рассмотрены вопросы приложений теории случайных процессов, включающие, в частности, проблему прогноза с использованием вероятностных моделей и методов.
Для студентов физико-математических и физико-технических специальностей вузов. |

Рассматриваются прямоугольный импульс без внутриимпульсной модуляции, ФКМ импульс, ЛЧМ импульс и квазинепрерывный сигнал. Анализируются автокорреляционные и взаимно корреляционные функции. Исследуется весовая обработка сигналов. Оцениваются энергетические потери при обнаружении сигналов. Проведена оценка интенсивности пассивных помех для различных условий применения сигналов. Для квазинепрерывных сигналов исследованы алгоритмы устранения неоднозначности измерений. Рассмотрены применения сигналов при радиолокационном обзоре и при обнаружении целей.
Для научных работников и радиоинженеров, занимающихся проектированием радиолокационных станций, а также для аспирантов и студентов соответствующих специальностей. |
