Available in PDF, EPUB and Kindle. Book excerpt: Management and Analysis of Biological Populations demonstrates the usefulness of optimal control theory in the management of biological populations and the Liapunov function in simulating an ecosystem model under large perturbations of its initial state and continual disturbances on its dynamics. The first chapter of the book introduces the topic by presenting the different models in ecology and discussing the stability concepts, the ecological engineering, and various relevant functions in ecosystem modeling. The next chapter contains a brief survey of static optimization techniques and optimal control theory for systems, which are modeled by differential and difference equations. Another chapter covers methods that use Liapunov and Liapunov-like functions to establish that a given population model is stable relative to finite perturbations of its initial state and that it is non-vulnerable relative to large continual disturbances. The book also covers fisheries and logistic modeling, including a discussion of a few management problems. Moreover, this reference considers stability in an ecosystem model with complexities due to species richness, nonlinearities, time delays, and spatial heterogeneity. Finally, it explains how to manage pests and greenhouse crops. The book is an excellent reference source for students and professionals in ecology and environmental engineering. Research professionals and extended workers in agriculture and agronomy will also find this book invaluable.

Download or read book A Speech Understanding System written by Alan Sander Hoffman and published by . This book was released on 1973 with total page 280 pages. Available in PDF, EPUB and Kindle. Book excerpt: A computer speech understanding program is used as an illustrative example of a typical program at Rand. The various elements of a complete speech processing procedure are illustrated. Processing of the electrical signal corresponds to the temporal variation of the pressure or acoustic waveform. There has to be a model of the language, with the rules and their variations specified, and a model of the user and an indication of what constraints he puts on the system. Semantic processing of these various elements allows the computer to interpret or understand what has been said.
Download or read book Theoretical Approaches to Biological Control written by Bradford A. Hawkins and published by Cambridge University Press. This book was released on 2008-10-14 with total page 428 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biological control is the suppression of pest populations using predators, parasitoids and pathogens. Historically, biological control has largely been on a trial-and-error basis, and has failed more often than it has succeeded. However by developing theories based upon fundamental population principles and the biological characteristics of the pest and agent, we can gain a much better understanding of when and how to use biological control. This book gathers together recent theoretical developments and provides a balanced guide to the important issues that need to be considered in applying ecological theory to biological control. It will be a source of productive and stimulating thought for all those interested in pest management, theoretical ecology and population biology.

Download or read book Fisheries Management written by Geoffrey Waugh and published by Routledge. This book was released on 2019-03-04 with total page 215 pages. Available in PDF, EPUB and Kindle. Book excerpt: Among the problems of the modern fisheries industry is the persistent trend toward the severe depletion of fish stocks, resulting in low catch rates and poor economic returns, along with unnecessary accumulations of capital investments. Dr. Waugh argues that these problems call for effective management procedures based on bioeconomic modelling, which integrates the population dynamics of fish resources with the economic processes of harvesting and marketing. Assessing developments in bioeconomic theory, Dr. Waugh discusses why recent advances have not been fully translated into improvements in the management of marine fisheries. He cites the difficulties of reaching a consensus concerning suitable objectives for fisheries management, as well as the problems of designing a regulatory framework to improve the operation of the industry. To illustrate the utility of bioeconomic modelling, Dr. Waugh presents case studies of two Australian fisheries. A dynamic, stochastic, numeric model is developed for the Exmouth Gulf Prawn Fishery to provide insights into the optimal exploitation of a yearly resource, where fluctuations in recruitment, natural mortality, and catchability are important. The study of the New South Wales Abalone Fishery highlights the difficulties of obtaining the necessary overview of a fishery and the problems in collecting the data required for modelling and management.

Download or read book On the Dynamics of Exploited Fish Populations written by Raymond J.H. Beverton and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 541 pages. Available in PDF, EPUB and Kindle. Book excerpt: Among the fishes, a remarkably wide range of biological adaptations to diverse habitats has evolved. As well as living in the conventional habitats of lakes, ponds, rivers, rock pools and the open sea, fish have solved the problems of life in deserts, in the deep sea, in the cold antarctic, and in warm waters of high alkalinity or of low oxygen. Along with these adaptations, we find the most impressive specializations of morphology, physiology and behaviour. For example we can marvel at the high-speed swimming of the marlins, sailfish and warm-blooded tunas, air-breathing in catfish and lungfish, parental care in the mouth-brooding cichlids, and viviparity in many sharks and toothcarps. Moreover, fish are of considerable importance to the survival of the human species in the form of nutritious, delicious and diverse food. Rational exploitation and management of our global stocks of fishes must rely upon a detailed and precise insight of their biology. The Chapman & Hall Fish and Fisheries Series aims to present timely volumes reviewing important aspects of fish biology. Most volumes will be of interest to research workers in biology, zoology, ecology and physiology but an additional aim is for the books to be accessible to a wide spectrum of non-specialist readers ranging from undergraduates and postgraduates to those with an interest in industrial and commercial aspects of fish and fisheries.
Download or read book Operations Research and Management in Fishing written by A. Guimarães Rodrigues and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 332 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over eleven years have passed since the last NATO sponsored meeting on Fishing which took the form of a Conference held in Trondheim in 1979. The proceedings contained in this book consist of papers presented in support of an Advanced Study Institute on Operations Research and Management in Fishing held at P6voa de Varzim, Portugal from March 25 to April 7 1990. It was originally intended to use the five themes, Production Functions and Management; Marine Fish Stocks; Fisheries Models; Fish Farming and Miscellaneous. There were no contributions on Fish Processing and the Fish Farming papers were not original. It was also decided to group the papers on Fisheries Models and Marine Fish Stocks together which means the proceedings has four headings: - Opening Session - Production Functions and Management - Marine Fish Stocks and Fisheries Models - Miscellaneous The contributions give a broad and complete overview of historical approaches and of recent trends on research in different sectors of fisheries. Criteria for quota distribution and schemes based on conclusions drawn from models and methods are presented. Surveillance methods are described in relation to species conservation and catch improvement. Different levels of regulatory enforcement are discussed and the implications of new technologies are introduced. Applications of Expert Systems to stock assessment and efficiency improvement in field sampling are presented. Models for fleet dispatch planning and fleet structure appraisal are introduced and procedures for operational capacity evaluation of fishery harbours are considered.
