It covers all the relevant topics along with the recent developments in the field. The book begins with an overview of operations research and then discusses the simplex method of optimization and duality concept along with the deterministic models such as post-optimality analysis, transportation and assignment models. While covering hybrid models of operations research, the book elaborates PERT (Programme Evaluation and Review Technique), CPM (Critical Path Method), dynamic programming, inventory control models, simulation techniques and their applications in mathematical modelling and computer programming. It explains the decision theory, game theory, queueing theory, sequencing models, replacement and reliability problems, information theory and Markov processes which are related to stochastic models. Finally, this well-organized book describes advanced deterministic models that include goal programming, integer programming and non-linear programming.

As the world of Indian journalism continues to grow, with print, television and electronic news constantly competing to outdo each other, veteran journalist Alok Mehta takes a close look at the lack of ethical journalism. In his essays, he makes a strong case for a journalistic code of conduct, similar to those in other countries such as the UK and USA, and outlines several recommendations Indian journalists must keep in mind to maintain their credibility and integrity in an increasingly corrupt environment. Not only must journalists expand the scope of their reporting, they must do so in a sensitive and aware manner, to maximise public awareness and to create and mould public opinion. Only then can their readers make informed choices and take strong stands on issues they believe in.

The subject matter of this book is to present the procedural steps required for modeling and simulating the basic dynamic system problems in SIMULINK (a supplementary part of MATLAB) which follow some definitive model. However, the key features of the text can be cited as follows: The book is on the whole a guiding tool for the undergraduate and graduate students of science and engineering who want to work out or simulate the classroom modeling problems using SIMULINK To check the understanding of SIMULINK output and deliberate the reliability on SIMULINK, analytical solutions of the model outputs are inserted in most chapters Since the text presents modeling ranging from elementary to advanced level, audience spectrum of the text includes engineers, teachers, researchers, and scientists who are beginners in using SIMULINK Know-how aspects of SIMULINK are covered in a made-easy way so that the average reader becomes benefited even if starting from the scratch Tabular block links at the end of each chapter required for a particular class of problems help the reader bring them in the model file and simulate quickly Over 300 classroom-modeling examples are simulated with clarity and systematic steps Appropriate for individual or classroom exercise There are ten chapters in the book bearing the following titles: Introduction to SIMULINK Modeling Mathematical Functions and Waves Modeling Ordinary Differential Equations Modeling Difference Equations Modeling Common Problems of Control Systems Modeling Some Signal Processing Problems Modeling Common Matrix Algebra Problems Modeling Common Statistics and Conversion Problems Fourier Analysis Problems Miscellaneous Modeling and Some Programming Issues

A cell phone's roaming feature allows the user to get service when traveling beyond the boundaries of his/her service provider. Wireless service providers make approximately 30% of their operating profit from roaming. But despite being a major source of income, roaming suffers from a number of technological problems in the handoff between networks. Signal strength is wildly variable, calls are frequently dropped, and quality of service is poor. Based upon training courses the author teaches at Agilent and Hewlett-Packard, this is the first book to give communications engineers the know-how to faultlessly design and manage roaming services.

Sex in Development examines how development projects around the world intended to promote population management, disease prevention, and maternal and child health intentionally and unintentionally shape ideas about what constitutes "normal" sexual practices and identities. From sex education in Uganda to aids prevention in India to family planning in Greece, various sites of development work related to sex, sexuality, and reproduction are examined in the rich, ethnographically grounded essays in this volume. These essays demonstrate that ideas related to morality are repeatedly enacted in ostensibly value-neutral efforts to put into practice a "global" agenda reflecting the latest medical science.Sex in Development combines the cultural analysis of sexuality, critiques of global development, and science and technology studies. Whether considering the resistance encountered by representatives of an American pharmaceutical company attempting to teach Russian doctors a "value free" way to offer patients birth control or the tension between Tibetan Buddhist ideas of fertility and the modernization schemes of the Chinese government, these essays show that attempts to make sex a universal moral object to be managed and controlled leave a host of moral ambiguities in their wake as they are engaged, resisted, and reinvented in different ways throughout the world.

This delightful and instructive history of invention shows why National Public Radio dubbed Tenner " the philosopher of everyday technology." Looking at how our inventions have impacted our world in ways we never intended or imagined, he shows that the things we create have a tendency to bounce back and change us.
The reclining chair, originally designed for brief, healthful relaxation, has become the very symbol of obesity. The helmet, invented for military purposes, has made possible new sports like mountain biking and rollerblading. The typewriter, created to make business run more smoothly, has resulted in wide-spread vision problems, which in turn have made people more reliant on another invention-- eyeglasses. As he sheds light on the many ways inventions surprise and renew us, Tenner considers where technology will take us in the future, and what we can expect from the devices that we no longer seem able to live without.

Passionate, succinct, chilling, closely argued, sometimes hilarious, touchingly well-intentioned, and essential.” —Margaret Atwood, The New York Review of Books

Nearly fifteen years ago, in The End of Nature, Bill McKibben demonstrated that humanity had begun to irrevocably alter and endanger our environment on a global scale. Now he turns his eye to an array of technologies that could change our relationship not with the rest of nature but with ourselves. He explores the frontiers of genetic engineering, robotics, and nanotechnology—all of which we are approaching with astonishing speed—and shows that each threatens to take us past a point of no return. We now stand, in Michael Pollan’s words, “on a moral and existential threshold,” poised between the human past and a post-human future. McKibben offers a celebration of what it means to be human, and a warning that we risk the loss of all meaning if we step across the threshold. Instantly acclaimed for its passion and insight, this wise and eloquent book argues that we cannot forever grow in reach and power—that we must at last learn how to say, “Enough.”

For Industrial Engineering courses focusing on logistic engineering and management.

An authoritative exploration of logistics management within the engineering design and development process, this book concentrates on the design, sustaining maintenance and support of systems from a lifecycle perspective. This is the only text that deals with logistics and system support: (1) as an integrated entity and an integral part of the overall structure of a total “system”; (2) from a total system life-cycle perspective—from the initial identification of a need through design and development, production, utilization and support, and retirement and material disposal; and (3) as a major consideration early in the system life cycle during the system engineering design and development process.

Journalism and mass communications professionals entering the innovative world of new media technology face a wave of challenging and often unanticipated ethical quandaries. "Digital Dilemmas: Ethical Issues for Online Media Professionals" is the first title in Blackwell Publishing's "Media and Technology" series (Alan B. Albarran, series editor). This important new text establishes a framework for discussing, understanding, and ultimately making sound decisions on meeting these ethical challenges. In addition, the book provides guidelines for approaching and making decisions from an ethical standpoint.

Part one of the text gives background and overview information to examine existing professional ethical codes and their applicability in the new media. Part two delves into the ethical dilemmas faced by all online communications professionals--privacy, speech and intellectual property. Part three warns the reader about three specific types of ethical hazards--speed vs. accuracy and quality; validating Internet sources; and blurring editorial with commercial information.

Through the use of historical summaries, discussion of specific problems, case study illustrations, critical thinking exercises, chapter summaries, key points, and recommended readings, each chapter comprehensively explores ethical issues. Aimed at students as well as practicing journalists and media professionals, "Digital Dilemmas" serves as the essential text and user's guide to the emerging ethical challenges facing those who work or plan to work in the online media.

For introductory courses (sophomore/junior) in Digital Signal Processing and Signals and Systems. Text may be used before the student has taken a course in circuits.

This text is derived from DSP First: A Multimedia Approach, published in 1997, which filled an emerging need for a new entry-level course not centered on analog circuits in the ECE curriculum. It was also successfully used in 80 universities as a core text for linear systems and beginning signal processing courses. This derivative product, Signal Processing First SPF contains similar content and presentation style, but focuses on analog signal processing. Note: DSP First: A Multimedia Approach remains in print for those who choose a digital emphasis for their introductory course.

[An] absorbing survey of oceanography . . . [this] elegant study is an excellent resource.­­Publishers Weekly

A fascinating examination of the earths oceans

This exhaustive overview of oceanography captures the excitement of discovery in the making. The Oceans opens up the world of ocean science to the general reader and raises significant questions about the future of the ancient, nurturing ocean itself.

The oceans cover more than 70 percent of the globe, yet less than 5 percent of that expanse has been explored. But, as Drs. Prager and Earle show in this vivid survey of ocean research, our knowledge is suddenly accelerating: various dives, soundings, computer analyses, and other probes are uncovering amazing facts about the 142 million square miles beneath the seas.
