Description : 'At a time when we are paying a heavy price for the collective delusion that being plugged in 24/7 is an express elevator to the top, The Off Switch reminds us that there is an alternative. Mark Cropley shows that intentionally switching off from work is not only essential for our well-being, it also allows for the unwinding and renewal that help us perform at our best when we switch back on.' Arianna Huffington Work better not longer– learn how to be more productive by switching off from work in the evenings, worrying less and facing the new working day fresh, full of energy and ambition. Work is a big part of our lives, but it's easier than ever to let it take over. Laptops, tablets and smartphones that are supposed to free us from the office actually bind us to it. If you've ever felt stressed as you checked your work email in the evenings, or found yourself unable to sleep worrying about tomorrow's meeting, then this is the book for you! Learning to flick THE OFF-SWITCH when you leave work is essential– not only for your sanity but also for your job. If you can learn to relax and rest effectively when you’re not at work, you can then get more done when you’re in the office. It’s a win-win solution! In this unique book, Professor Mark Cropley, a world expert in how we recover from the working day, blends engaging real-life case studies, clinical expertise and evidence-based techniques to provide a complete guide for how to switch off better – get more enjoyment from your free time, and still get more done.
Description : 'Sensational. Wildly hilarious. An amazing read' - Stephen Fry 'Andy Kershaw is a compulsive truth-teller and he does it with verve, wit and passion. He is one of the few truly original voices in broadcasting and his book is already a classic' - Fergal Keane Andy Kershaw truly has no off switch. As a teenager he was promoting major rock gigs. He was Billy Bragg's driver and roadie one day and presenting Whistle Test and Live Aid the next. A passionate music enthusiast, he is a man with an obsessive curiosity about the world. Over a twenty-five year career, he has worked for the Rolling Stones and Bruce Springsteen, shared an office with John Peel and amassed a record collection that weighs seven tons. He has won more Sony Radio awards than any other broadcaster. He has visited 97 countries and as a foreign correspondent, filed numerous reports for Radio 4. He was also one of the few journalists present during the Rwanda genocide. The past few years have seen him go through a turbulent time in his personal life, but he has put this behind him, written his story and returned to the airwaves fronting the BBC's Music Planet series. Rebel. Maverick. Music fanatic. Andy Kershaw shares the story of his life with candour, insight, immediacy and incredible humour.
Description : Switch-Mode Power Converters introduces an innovative, highly analytical approach to symbolic, closed-form solutions for switched-mode power converter circuits. This is a highly relevant topic to power electronics students and professionals who are involved in the design and analysis of electrical power converters. The author uses extensive equations to explain how solid-state switches convert electrical voltages from one level to another, so that electronic devices (e.g., audio speakers, CD players, DVD players, etc.) can use different voltages more effectively to perform their various functions. Most existing comparable books published as recently as 2002 do not discuss closed-loop operations, nor do they provide either DC closed-loop regulation equations or AC loop gain (stability) formulae. The author Wu, a leading engineer at Lockheed Martin, fills this gap and provides among the first descriptions of how error amplifiers are designed in conjunction with closed-loop bandwidth selection. BENEFIT TO THE READER: Readers will gain a mathematically rigorous introduction to numerous, closed-form solutions that are readily applicable to the design and development of various switch-mode power converters. Provides symbolic, closed-form solutions for DC and AC studies Provides techniques for expressing close-loop operation Gives readers the ability to perform closed-loop regulation and sensitivity studies Gives readers the ability to design error amplifiers with precision Employs the concept of the continuity of states in matrix form Gives accelerated time-domain, steady-state studies using Laplace transform Gives accelerated time-domain studies using state transition Extensive use of matrix, linear algebra, implicit functions, and Jacobian determinants Enables the determination of power stage gain that otherwise could not be obtained

Description : Over the last decade, fluorescence has become the dominant tool in biotechnology and medical imaging. These exciting advances have been underpinned by the advances in time-resolved techniques and instrumentation, probe design, chemical / biochemical sensing, coupled with our furthered knowledge in biology. Complementary volumes 9 and 10, Advanced Concepts of Fluorescence Sensing: Small Molecule Sensing and Advanced Concepts of Fluorescence Sensing: Macromolecular Sensing, aim to summarize the current state of the art in fluorescent sensing. For this reason, Drs. Geddes and Lakowicz have invited chapters, encompassing a broad range of fluorescence sensing techniques. Some chapters deal with small molecule sensors, such as for anions, cations, and CO2, while others summarize recent advances in protein-based and macromolecular sensors. The Editors have, however, not included DNA or RNA based sensing in this volume, as this were reviewed in Volume 7 and is to be the subject of a more detailed volume in the near future.
Description : When designing switch-mode power supplies (SMPSs), engineers need much more than simple "recipes" for analysis. Such plug-and-go instructions are not at all helpful for simulating larger and more complex circuits and systems. Offering more than merely a "cookbook," Practical Computer Analysis of Switch Mode Power Supplies provides a thorough understanding of the essential requirements for analyzing SMPS performance characteristics. It demonstrates the power of the circuit averaging technique when used with powerful computer circuit simulation programs. The book begins with SMPS fundamentals and the basics of circuit averaging models, reviewing most basic topologies and explaining all of their various modes of operation and control. The author then discusses the general analysis requirements of power supplies and how to develop the general types of SMPS models, demonstrating the use of SPICE for analysis. He examines the basic first-order analyses generally associated with SMPS performance along with more practical and detailed methods for developing SMPS and component models. The final chapter features the circuit-averaging macromodel of the integrated circuit PWM controller illustrated through analyses of three power supplies. Practical Computer Analysis of Switch Mode Power Supplies builds a strong foundation on the principles of SMPS analysis, enabling further development and advancement of the techniques while supplying meaningful insight into the process.
