Objective English for Competitive Examination

    This text is a lucid presentation of the principles of working of all types of sensors and transducers which form the prime components of the instrumentalisation systems.

    It offers a broad view of the functioning of the public sector and its role in a democratic society. Widely adopted in previous editions,the new Fifth Edition has been reworked throughout,including extensive updating to allow for legislative changes,changes in data,and new theoretical developments. It includes in-depth coverage of the Tax Reform Act of 1986 and its implications today.

    Len Fisher turns his attention to the science of cooperation in his lively and thought-provoking book. Fisher shows how the modern science of game theory has helped biologists to understand the evolution of cooperation in nature, and investigates how we might apply those lessons to our own society. In a series of experiments that take him from the polite confines of an English dinner party to crowded supermarkets, congested Indian roads, and the wilds of outback Australia, not to mention baseball strategies and the intricacies of quantum mechanics, Fisher sheds light on the problem of global cooperation. The outcomes are sometimes hilarious, sometimes alarming, but always revealing. A witty romp through a serious science, Rock, Paper, Scissors will both teach and delight anyone interested in what it what it takes to get people to work together.

    Some of these problems are new, while others have puzzled and bewitched thinkers across the ages. Such challenges offer a tantalizing glimpse of the field's unlimited potential, and keep mathematicians looking toward the horizons of intellectual possibility.In Visions of Infinity, celebrated mathematician Ian Stewart provides a fascinating overview of the most formidable problems mathematicians have vanquished, and those that vex them still. He explains why these problems exist, what drives mathematicians to solve them, and why their efforts matter in the context of science as a whole. The three-century effort to prove Fermat's last theorem—first posited in 1630, and finally solved by Andrew Wiles in 1995—led to the creation of algebraic number theory and complex analysis. The Poincaré conjecture, which was cracked in 2002 by the eccentric genius Grigori Perelman, has become fundamental to mathematicians' understanding of three-dimensional shapes. But while mathematicians have made enormous advances in recent years, some problems continue to baffle us. Indeed, the Riemann hypothesis, which Stewart refers to as the “Holy Grail of pure mathematics,” and the P/NP problem, which straddles mathematics and computer science, could easily remain unproved for another hundred years.An approachable and illuminating history of mathematics as told through fourteen of its greatest problems, Visions of Infinity reveals how mathematicians the world over are rising to the challenges set by their predecessors—and how the enigmas of the past inevitably surrender to the powerful techniques of the present.

    All of a sudden, she finds herself pretending—unwillingly at that—to be his girlfriend to make his ex jealous.Now, not only does she have to deal with dirty looks from the girls in school who want Kenji for themselves, but her supposed boyfriend is getting on her nerves. He's hotheaded, never seems to agree with her on anything—and everything about him screams gangster.Has Athena gotten herself into more trouble than she can handle? Or has she actually found herself a boy she can call hers—gangster be damned?

    

    It begins by introducing students to the basics of communication systems without using probabilistic theory. Only after a solid knowledge base--an understanding of how communication systems work--has been built are concepts requiring probability theory covered. This third edition has been thoroughly updated and revised to include expanded coverage of digital communications. New topics discussed include spread-spectrum systems, cellular communication systems, global positioning systems (GPS), and an entire chapter on emerging digital technologies (such as SONET, ISDN, BISDN, ATM, and video compression). Ideal for the first communication systems course for electrical engineers, Modern Digital and Analog Communication Systems offers students a superb pedagogical style; it consistently does an excellent job of explaining difficult concepts clearly, using prose as well as mathematics. The author makes every effort to give intuitive insights--rather than just proofs--as well as heuristic explanations of theoretical results wherever possible. Featuring lucid explanations, well-chosen examples clarifying abstract mathematical results, and excellent illustrations, this unique text is highly informative and easily accessible to students.

    Following closely behind is y, or gamma, a constant that arises in many mathematical areas yet maintains a profound sense of mystery. In a tantalizing blend of history and mathematics, Julian Havil takes the reader on a journey through logarithms and the harmonic series, the two defining elements of gamma, toward the first account of gamma's place in mathematics. Introduced by the Swiss mathematician Leonhard Euler (1707-1783), who figures prominently in this book, gamma is defined as the limit of the sum of 1 + 1/2 + 1/3 + . . . Up to 1/n, minus the natural logarithm of n--the numerical value being 0.5772156. . . . But unlike its more celebrated colleagues π and e, the exact nature of gamma remains a mystery--we don't even know if gamma can be expressed as a fraction. Among the numerous topics that arise during this historical odyssey into fundamental mathematical ideas are the Prime Number Theorem and the most important open problem in mathematics today--the Riemann Hypothesis (though no proof of either is offered!). Sure to be popular with not only students and instructors but all math aficionados, Gamma takes us through countries, centuries, lives, and works, unfolding along the way the stories of some remarkable mathematics from some remarkable mathematicians.-- "Notices of the American Mathematical Society"

    However, we live in an economic era when making money is no longer as easy as investing in good stocks and mutual funds and watching them appreciate over time. Today’s volatile and interconnected financial system means that the stocks you own can come crashing down today and climb even higher tomorrow due to developments in Europe and the Middle East. Yet, investing in the stock market still provides one of the best returns for your savings and the only way through which an average income earner can hope to become financially free. This is why it is important for you to become a savvy investor who knows how to achieve consistent profits —even in an uncertain global economy.In this book, you are going to learn to…• Invest in Winning Stocks That Generate High Double-Digit Returns• Identify Market Uptrends and Downtrends Accurately• Hedge and Protect Your Portfolio from Market Crashes• Short Sell and Profit in a Down-trending Market• Manage Your Risks and Maximize Your Returns• Develop the Psychology of a Disciplined Investor• Build a Winning Portfolio That Suits Your Investment Goals• Build a Passive Income Stream from Real Estate Investment Trusts• Build a Multi-Million Dollar Net Worth on an Average Income

    But some of the passengers on board luckily survived. They survived at chilling for many days in hope for help by eating the flesh from dead bodies of their own friends who died in Crash.

    In this lively and groundbreaking new book, economist Ian Ayres shows how today's best and brightest organizations are analyzing massive databases at lightening speed to provide greater insights into human behavior. They are the Super Crunchers. From internet sites like Google and Amazon that know your tastes better than you do, to a physician's diagnosis and your child's education, to boardrooms and government agencies, this new breed of decision makers are calling the shots. And they are delivering staggeringly accurate results. How can a football coach evaluate a player without ever seeing him play? Want to know whether the price of an airline ticket will go up or down before you buy? How can a formula outpredict wine experts in determining the best vintages? Super crunchers have the answers. In this brave new world of equation versus expertise, Ayres shows us the benefits and risks, who loses and who wins, and how super crunching can be used to help, not manipulate us.Gone are the days of solely relying on intuition to make decisions. No businessperson, consumer, or student who wants to stay ahead of the curve should make another keystroke without reading Super Crunchers.
