An interdisciplinary approach to understanding queueing and graphical networks In today's era of interdisciplinary studies and research activities, network models are becoming increasingly important in various areas where they have not regularly been used. Combining techniques from stochastic processes and graph theory to analyze the behavior of networks, Fundamentals of Stochastic Networks provides an interdisciplinary approach by including practical applications of these stochastic networks in various fields of study, from engineering and operations management to communications and the physical sciences. The author uniquely unites different types of stochastic, queueing, and graphical networks that are typically studied independently of each other. With balanced coverage, the book is organized into three succinct parts: Part I introduces basic concepts in probability and stochastic processes, with coverage on counting, Poisson, renewal, and Markov processes Part II addresses basic queueing theory, with a focus on Markovian queueing systems and also explores advanced queueing theory, queueing networks, and approximations of queueing networks Part III focuses on graphical models, presenting an introduction to graph theory along with Bayesian, Boolean, and random networks The author presents the material in a self-contained style that helps readers apply the presented methods and techniques to science and engineering applications. Numerous practical examples are also provided throughout, including all related mathematical details. Featuring basic results without heavy emphasis on proving theorems, Fundamentals of Stochastic Networks is a suitable book for courses on probability and stochastic networks, stochastic network calculus, and stochastic network optimization at the upper-undergraduate and graduate levels. The book also serves as a reference for researchers and network professionals who would like to learn more about the general principles of stochastic networks.

Полный вариант заголовка: «A view of the internal evidence of the Christian religion / [by Soame Jenyns]».
Manufacturers can be green and highly profitable at the same time Profits do not have to be sacrificed to environmental responsibility, or vice versa. Following this book's tested and proven approach, readers discover how to create and operate manufacturing facilities that are highly profitable while meeting or exceeding the environmental standards of their local community, state, and federal governments. The authors' approach is broad in scope, setting forth the roles and responsibilities of organizational functions such as marketing, product design, manufacturing technology, management, and human resources. The book begins with an overview explaining why profitability and green manufacturing must be viewed as a single objective. Next, the book becomes a «how to» guide to creating and maintaining an environmentally compliant and profitable manufacturing operation, with chapters covering: Manufacturing, waste, and regeneration Building a decision-making model Environmental regulation, standards, and profitability Case studies Tools used to improve manufacturing operations The facility Applying the profitable and compliant process chart The final chapter is dedicated to a step-by-step approach in the application and use of the profitable and compliant process chart, a core working tool discussed in the book. In this chapter, several actual manufacturing applications, along with their worksheets, are presented to illustrate how this approach can minimize resources and waste. Armed with this comprehensive systems approach, readers will no longer view profitability and green manufacturing as two opposing goals. Instead, they'll have the tools and knowledge needed to create and maintain a manufacturing operation that is both profitable and green.
Generally a laser (light amplification by stimulated emission of radiation) is defined as “a device which uses a quantum mechanical effect, stimulated emission, to generate a coherent beam of light from a lasing medium of controlled purity, size, and shape”. Laser material processing represents a great number of methods, which are rapidly growing in current and different industrial applications as new alternatives to traditional manufacturing processes. Nowadays, the use of lasers in manufacturing is an emerging area with a wide variety of applications, for example, in electronics, molds and dies, and biomedical applications.
