The advantages of optical communications are many: ultra-high speed, highly reliable information transmission, and cost-effective modulation and transmission links to name but a few. It is no surprise that optical fiber communications systems are now in extensive use all over the world. Along with software and microelectronics, optical communication represents a key technology of modern telecommunication systems. Optical Communications: Components and Systems provides the basic material required for advanced study in theory and applications of optical fiber and space communication systems. After a review of some fundamental background material, component-based chapters discuss all relevant passive and active optical and optoelectronic components used in point-to-point links and in networks. Systems chapters address the analysis and optimization of both incoherent and coherent systems, introduce fiber optic link design, and discuss physical limits. The authors also provide an overview of applications such as optical networks and optical free-space communications. The advanced interactive multimedia communications of today and the future rely on optical fiber and space communication techniques. Optical Communications: Components and Systems offers engineers and physicists a working reference for the selection and design of optical communication systems and provides engineering students with a valuable text that prepares them for work in this essential and rapidly growing field.

Principles of Polymer Science introduces several basic and advanced aspects of polymers for the undergraduate and graduate students in chemistry, chemical engineering, and materials science. The second and thoroughly revised edition includes the technical aspects of synthesis, characterization, behavior, and technology in a straightforward and lucid manner. Separate chapters on natural, inorganic, and specialty polymers will attract readers from inderdisciplinary courses. The book presents several laboratory experiments, multiple choice questions, a glossary of technical words, and brief sketches of polymer pioneers.

Based on a course developed by the author, Mechanics provides an introduction to classical mechanics. Each chapter begins with an introduction to the topics under discussion and is followed by precise definitions, propositions, and theorems and ends with exercises that reinforce students understanding. The treatment of the subject is mathematical, but the mathematics used is elementary. In fact, all the mathematics presented involve basic vector algebra and differential calculus of vector valued functions of a real variable. The author avoids explaining the underlying geometry in an explicit manner. Instead, he presents geometric discussions in a kinematical disguise - a treatment beneficial not only to the mathematics student but also to students of physics and engineering.

Essential for students of both undergraduate and postgraduate classes, Modern Plant Physiology addresses new developments in tissue culture, stress physiology, and secondary metabolities. This detailed and comprehensive handbook, written by a renowned figure in botanical education, focuses on many essential concepts, including: the metabolisms of nitrogen, amino acids, protein, fat, and nucleic acid; photosynthesis; photorespiration; hormones; senescence, aging and abscission; photoperiodism; and the physiology of flowering. The text offers tabulated differences between allied processes such as Fluorescence and Phosphorescence, thus providing a clear conception and better understanding of the subject matter.

Reducing crop losses, minimizing pesticide use, avoiding pesticide residues, increasing farmer's income and enhancing environmental health are the hallmarks of sustainable agriculture. How can this be achieved through the use of green pesticides? This book deals with this question.

Power system oscillations without a big disturbance occur spontaneously in a power system and if they are not damped out properly may lead to grid failure. In this book we examine the methodology to study this phenomenon from several angles.
