Book Description
Ultra Wide Band Technology (UWB) has reached a level of maturity that allows us to offer wireless links with either high or low data rates. These wireless links are frequently associated with a location capability for which ultimate accuracy varies with the inverse of the frequency bandwidth. Using time or frequency domain waveforms, they are currently the subject of international standards facilitating their commercial implementation. Drawing up a complete state of the art, Ultra Wide Band Antennas is aimed at students, engineers and researchers and presents a summary of internationally recognized studies.

Book Description
Nonnegative matrix factorization (NMF) in its modern form has become a standard tool in the analysis of high-dimensional data sets. This book provides a comprehensive and up-to-date account of the most important aspects of the NMF problem and is the first to detail its theoretical aspects, including geometric interpretation, nonnegative rank, complexity, and uniqueness. It explains why understanding these theoretical insights is key to using this computational tool effectively and meaningfully. Nonnegative Matrix Factorization is accessible to a wide audience and is ideal for anyone interested in the workings of NMF. It discusses some new results on the nonnegative rank and the identifiability of NMF and makes available MATLAB codes for readers to run the numerical examples presented in the book. Graduate students starting to work on NMF and researchers interested in better understanding the NMF problem and how they can use it will find this book useful. It can be used in advanced undergraduate and graduate-level courses on numerical linear algebra and on advanced topics in numerical linear algebra and requires only a basic knowledge of linear algebra and optimization.

Book Description
Suitable for both individual and group learning, Engineering Acoustics focuses on basic concepts and methods to make our environments quieter, both in buildings and in the open air. The author’s tutorial style derives from the conviction that understanding is enhanced when the necessity behind the particular teaching approach is made clear. He also combines mathematical derivations and formulas with extensive explanations and examples to deepen comprehension. Fundamental chapters on the physics and perception of sound precede those on noise reduction (elastic isolation) methods. The last chapter deals with microphones and loudspeakers. Moeser includes major discoveries by Lothar Cremer, including the optimum impedance for mufflers and the coincidence effect behind structural acoustic transmission. The appendix gives a short introduction on the use of complex amplitudes in acoustics.

Book Description
At the age of twenty-eight, Marty Ellis is still a bachelor who graduated with a major in journalism and a minor in photojournalism. He enjoys his life with various girlfriends while knocking back drinks in bars, going out to dinner, and rolling in the sheets. Yet inevitably, he grows tired of these surface-level-only feelings, shells out his standard goodbye speech, and moves on. However, using only his body and saying sayonara to his love lifeaEUR(tm)s revolving door is not how he wants to live for the rest of his life. How will he ever know what true love feels like if he doesnaEUR(tm)t ascertain how to actually give it? In what way will he begin to be able to discover the whole package that runs beneath the surface of a woman? Unexpectedly, Marty is blindsided when his best friend invites him to leave New Jersey for a weekend trip. Lauren Morris is a beautiful thirty-two-year-old woman who, after graduating at the age of twenty-one with a masteraEUR(tm)s degree in business, took a huge leap of faith and purchased an old farmhouse in Vermont. After ten years of hard work and sweat equity, she has transformed it into a beautiful inn that has become extremely lucrative. But winter is fast approaching, and she is dreading that feeling of loneliness that is connected to darkened afternoons and long, empty nights. Will a man ever enter her life? One that she could love and perhaps be with until death due them part? After meeting Marty, Lauren begins to consider if this man might be the one she has been waiting for her whole life. But then again, she is older than he is; long distance relationships hardly ever work out; and sudden heartbreaking unforeseen events rock both of their worlds. And if they do fall in love, which one of them will have to make the ultimate sacrifice and give up what theyaEUR(tm)ve worked so hard to achieve in order to be together? With so many changes causing so many challenges, will they get through them together, or will one push the other away?

Book Description
Connected objects today present a range of opportunities in medicine. We live in a new digital era where the monitoring and analysis of one's own health information no longer belongs solely to the realm of science fiction. The success of these new devices resides in their usage, which integrates seamlessly into the daily life of the user in order to continually collect the maximum amount of data. These medical connected devices therefore constitute a new hope in transforming user experience as well as the care pathway. They offer a better level of support and a better quality of life for those suffering from chronic illnesses or mental, sensorial or physical disabilities. However, these solutions also pose systematic problems, especially regarding the risks linked to their usage. This book presents a cartography which clearly details all the potential risk scenarios linked to the usage of connected devices as well as the actions which should be undertaken to promote balanced governance and guarantee the development of high-quality medical devices. - Aims to help the reader understand the difference between a connected object and a medical connected device - Identifies and evaluates all the potential risks and perspectives associated with the use of connected medical devices - Shows how to make a comprehensive risk analysis with standards like ISO 31000 and 14971
