Book Description
Autonomie énergétique des systèmes embarqués sans fil et sans batterie examine la question de l’autonomie énergétique des systèmes embarqués sans fil, en particulier dans le contexte aéronautique où la problématique du poids et de la complexité du câblage électrique sont essentiels alors que de nouveaux besoins en termes de réseaux de capteurs apparaissent. Cet ouvrage propose des éléments de réponse aux problématiques concernant l’autonomie énergétique utilisant la récupération de l’énergie ambiante. Il décrit tout d’abord le cadre général des réseaux de capteurs sans fil et de l’autonomie énergétique. Les architectures de circuits de traitement de l’énergie sont ensuite abordées. Fruit d’une collaboration ancienne avec un avionneur, cet ouvrage présente enfin des applications réelles et concrètes et traite aussi bien des aspects généraux que pratiques – principes physiques, architectures, choix et qualification des composants.

Book Description
From the #1 New York Times bestselling author of The Giver of Stars and the forthcoming Someone Else's Shoes, discover the love story that captured over 20 million hearts in Me Before You, After You, and Still Me. They had nothing in common until love gave them everything to lose . . . Louisa Clark is an ordinary girl living an exceedingly ordinary life—steady boyfriend, close family—who has barely been farther afield than their tiny village. She takes a badly needed job working for ex–Master of the Universe Will Traynor, who is wheelchair bound after an accident. Will has always lived a huge life—big deals, extreme sports, worldwide travel—and now he’s pretty sure he cannot live the way he is. Will is acerbic, moody, bossy—but Lou refuses to treat him with kid gloves, and soon his happiness means more to her than she expected. When she learns that Will has shocking plans of his own, she sets out to show him that life is still worth living. A Love Story for this generation and perfect for fans of John Green’s The Fault in Our Stars, Me Before You brings to life two people who couldn’t have less in common—a heartbreakingly romantic novel that asks, What do you do when making the person you love happy also means breaking your own heart?

Book Description
Electrochemical capacitors are electrochemical energy storage devices able to quickly deliver or store large quantities of energy. They have stimulated numerous innovations throughout the last 20 years and are now implemented in many fields. Supercapacitors Based on Carbon or Pseudocapacitive Materials provides the scientific basis for a better understanding of the characteristics and performance of electrochemical capacitors based on electrochemical double layer electrodes or pseudocapacitive materials, as well as providing information on the design and conception of new devices such as lithium-ion capacitors. This book details the various applications of supercapacitors, ranging from power electronics and stationary use, to transportation (hybrid vehicles, trams, planes, etc.). They are increasingly used in the automotive sector, especially as part of stop/start systems that have allowed for energy recovery through braking and reduced fuel consumption.

Book Description
This book is part of a set of books which offers advanced students successive characterization tool phases, the study of all types of phase (liquid, gas and solid, pure or multi-component), process engineering, chemical and electrochemical equilibria, and the properties of surfaces and phases of small sizes. Macroscopic and microscopic models are in turn covered with a constant correlation between the two scales. Particular attention has been given to the rigor of mathematical developments. This second volume in the set is devoted to the study of liquid phases.

Macroscopic and microscopic models are in turn covered with a constant correlation between the two scales. Particular attention has been given to the rigor of mathematical developments. This volume, the final of the Chemical Thermodynamics Set, offers an in-depth examination of chemical thermodynamics. The author uses systems of liquids, vapors, solids and mixtures of these in thermodynamic approaches to determine the influence of the temperature and pressure on the surface tension and its consequences on specific heat capacities and latent heats. Electro-capillary phenomena, the thermodynamics of cylindrical capillary and small volume-phases are also discussed, along with a thermodynamic study of the phenomenon of nucleation of a condensed phase and the properties of thin liquid films. The final chapters discuss the phenomena of physical adsorption and chemical adsorption of gases by solid surfaces. In an Appendix, applications of physical adsorption for the determination of the specific areas of solids and their porosity are given.

Book Description
The electrochemical energy storage is a means to conserve electrical energy in chemical form. This form of storage benefits from the fact that these two energies share the same vector, the electron. This advantage allows us to limit the losses related to the conversion of energy from one form to another. The RS2E focuses its research on rechargeable electrochemical devices (or electrochemical storage) batteries and supercapacitors. The materials used in the electrodes are key components of lithium-ion batteries. Their nature depend battery performance in terms of mass and volume capacity, energy density, power, durability, safety, etc. This book deals with current and future positive and negative electrode materials covering aspects related to research new and better materials for future applications (related to renewable energy storage and transportation in particular), bringing light on the mechanisms of operation, aging and failure.

Book Description
Building Wireless Community Networks is about getting people online using wireless network technology. The 802.11b standard (also known as WiFi) makes it possible to network towns, schools, neighborhoods, small business, and almost any kind of organization. All that's required is a willingness to cooperate and share resources. The first edition of this book helped thousands of people engage in community networking activities. At the time, it was impossible to predict how quickly and thoroughly WiFi would penetrate the marketplace. Today, with WiFi-enabled computers almost as common as Ethernet, it makes even more sense to take the next step and network your community using nothing but freely available radio spectrum. This book has showed many people how to make their network available, even from the park bench, how to extend high-speed Internet access into the many areas not served by DSL and cable providers, and how to build working communities and a shared though intangible network. All that's required to create an access point for high-speed Internet connection is a gateway or base station. Once that is set up, any computer with a wireless card can log onto the network and share its resources. Rob Flickenger built such a network in northern California, and continues to participate in network-building efforts. His nuts-and-bolts guide covers: Selecting the appropriate equipment Finding antenna sites, and building and installing antennas Protecting your network from inappropriate access New network monitoring tools and techniques (new) Regulations affecting wireless deployment (new) IP network administration, including DNS and IP Tunneling (new) His expertise, as well as his sense of humor and enthusiasm for the topic, makes Building Wireless Community Networks a very useful and readable book for anyone interested in wireless connectivity.
