Soft cover. Zustand: New. "Mathematical Biology is not as hierarchical and systematic as other areas of mathematics. However, one topic that is invariably included in any textbook on quantitative ecology is population dynamics. This book attempts to present in a systematic way the most common and elementary models of population growth. In this book the term population is used in a very general sense and hence the models can be applied to study the evolution of any type of biological organism. In each chapter the models are arranged in the order of mathematical complexity. The first chapter presents an overview of mathematical models and their characteristics. Chapter 2 discusses at length various discrete models of population growth. While chapter 3 discusses the classical deterministic models, chapter 4 includes extensions and recent modifications of the models presented in the previous chapter. The qualitative solutions of the models, which are sometimes more valuable and useful than quantitative solutions, are included in chapter 5. Properties of the logistic map, bifurcation diagrams, feigenbaum constant, an introduction to chaos and Lyapunov exponent are some of the topics covered in this chapter. Chapter 6 is devoted to classical models of interaction between two different species. Chapter 7 presents models on human and plant epidemiology. Finally, chapter 8 presents an introduction to stochastic models. The pre-requisites assumed are knowledge in difference equations, differential equations, matrix algebra and probability theory. A unique feature of the book is the inclusion of MATLAB M-files at the end of each chapter. These programs will definitely facilitate the reader to gain greater depth of knowledge about the models discussed in the respective chapter and obtain not only numerical solutions but also graphical understanding. The book can be prescribed for one semester course for postgraduate students or as an elective subject at advanced undergraduate level. The lucid presentation of the mathematical models interweaved with MATLAB programs would make this book an ideal one for the graduate and postgraduate students specializing in quantitative biology.".

Hardcover. Zustand: New. 2nd Edition. The Present book is unique in that it seeks to blend the theory of the Production Economics with empirical analysis of exclusively Indian situations. The applications presented here are from research works relating to local issues of the irrigation sector of the southern States of India, particularly Tamil Nadu. The material presented, both theoretical and empirical have been extensively classroom tested over the past two decades. The book contains twelve chapters. Starting with the first chapter on Agricultural Production Process- Selected Agro-economics Procedures explaining the production situation that are analyzed in the book. The second chapter Mathematical Analysis of Production Relationships presents a concise summary of the basic production economics theory forming the basis of subsequent chapters. The concept of the production function that forms the fundamental tool of production economics analysis is reviewed and its conceptual extensions leading to various decision making situations are explored. The subsequent chapters extend the basic theoretical analysis with illustrated empirical applications. These chapters cover the analytical approach to economic optimum, decision making with no risk and uncertainty in agriculture, trend/growth specifications and measurement of inequality, technology, input use and factor shares, economic efficiency in agricultural production, yield gaps, and yield penalties and yield declines. The final two chapters extend the analytical framework from production function analysis to programming approaches and the techniques of project evaluation. The lucid presentation of theory mingled with applications would make this book an ideal one for the graduate and postgraduate students specializing in production economics.
