Radiation Dosimetry, Second Edition, Volume I: Fundamentals describes the significant aspects and fundamentals of radiation dosimetry. This books deals with the concepts and units of dosimetry; special problems of energy deposition in the microscopic domain; interactions of x and y rays, charged particles, and neutrons with matter; mathematical theory of radiation fields; ionization; and cavity-chamber theory. Other topics discussed include the LET distributions, Compton and photoelectric effect, pair production by photons, dosimetry principles, and interactions of neutrons with tissue elements. The calculation of neutron dose in large objects; ionization in gases, liquids, and solids; and cavity dimensions comparable with the electron ranges are also deliberated. This publication likewise covers the measurement of absorbed dose and exposure and application of cavity theory to devices other than the ionization chamber. This volume is a valuable reference for radiation workers, but is also beneficial to students and researchers interested in radiation dosimetry.

eBook
9 7 8 - 1 - 4 8 3 1 - 9 4 6 3 - 9

Advances in Control Systems: Theory and Applications, Volume 6 provides information pertinent to the significant progress in the field of control and systems theory and applications. This book presents the higher level of automata, which represent the embodiment of the application of artificial intelligence techniques to control system design and may be described as self-organizing systems. Organized into four chapters, this volume begins with an overview of the existing technology in learning control system. This text then demonstrates how to apply artificial intelligence techniques to the designs of off-line and on-line learning control systems. Other chapters consider the decomposition methods and the associated multilevel optimization techniques applicable to control system optimization problems. This book discusses as well the complex optimal system control problems applied to the trajectory optimization problem. The final chapter deals with systems described by partial differential equations. This book is a valuable resource for control system engineers.

Ecology of Insect Vector Populations

Ecology of Insect Vector Populations provides a review and appraisal of the ecology of insect vectors of disease, with particular attention to the problems of sampling adult insect vector populations. The book examines the manner in which the inter-related problems of insect ecology, behavior, and population sampling have been explored over a wide range of investigations on disease vectors. The text focuses mainly on the study of blood-sucking dipterous insects such as tse-tse flies, mosquitoes, black-flies, and midges along with the appraisal of relevant studies on house-fly and blow-fly populations. The studies of the ecology of the wingless vectors of disease or plague such as the fleas are carried out extensively. The dissertation will be of interest to medical entomologists, animal ecologists, and epidemiologists.

Advances in Control Systems: Theory and Applications, Volume 5 provides information pertinent to the significant progress in the field of control and systems theory and applications. This book presents the problem of the optimal control of a system. Organized into six chapters, this volume begins with an overview of the fundamental conditions in the calculus of variations that are basic to the optimal control problem. This text then examines one of the basic problems in control and systems theory in general. Other chapters consider a number of rather basic results in optimal nonlinear filtering and describe the characteristic function of the state of vector of a nonlinear system. This book discusses as well a significant application area of control and systems theory, which is the optimal control of nuclear reactors. The final chapter deals with optimal control with bounds on the state variables. This book is a valuable resource for practicing engineers.

Weather Studies presents thorough discussions on various aspects of weather and weather studies. This text first presents the methods of measuring the weather, including measuring the temperature, humidity, rainfall, snowfall, visibility, wind force and direction, and pressure. Then, this book explains how to put these measurements in graphs to better present the data. This topic is followed by discussions on “weather in pairs,” or the relationships of weather measurements, such as of temperature and pressure, wind, and humidity, as well as of visibility and wind direction and humidity. This book ends by discussing local weather and forecasting the weather. This selection will be very invaluable to those studying the weather, including weather researchers, meteorologists, and students of meteorology.

Fruit Growing studies fruits, including its characterization and kinds; essential agricultural, horticultural, and silvicultural practices; and consumption. This book first qualifies what fruit is and then discusses some fruits such as berries and bush fruits. Various practices in growing, maintaining, and harvesting fruits are then examined, including cutting, layering, pruning, stooling, grafting, and pruning. How to plan and maintain a fruit garden is also explained. The latter part concerns itself with fruit storage, preparation, and record keeping. This text is a very helpful guide for those interested in putting up their own fruit garden, as well as to those in the field of agriculture, horticulture, human nutrition, and food technology.
