Available in PDF, EPUB and Kindle. Book excerpt: UN CERTAIN NOMBRE DE PROBLEMES D'ACTUALITE EN COMPATIBILITE ELECTROMAGNETIQUE (CEM) SONT RELATIFS A L'EMISSIVITE DE SYSTEMES ELECTRIQUES OU ELECTRONIQUES. LES VALEURS DU CHAMP ELECTROMAGNETIQUE RAYONNE PAR DE TELLES STRUCTURES SONT PARFAITEMENT DEFINIES DES LORS QUE L'ON CONNAIT LEUR DISTRIBUTION DE COURANT. DANS CETTE ETUDE, NOUS NOUS INTERESSONS A DES STRUCTURES FILAIRES AERIENNES COMPOSEES DE CONDUCTEURS CYLINDRIQUES PARFAITS, SITUEES AU-DESSUS D'UN SOL PARFAITEMENT CONDUCTEUR OU DE CONDUCTIVITE FINIE, ET POUVANT ETRE EXCITEES PAR UN GENERATEUR DE TENSION OU SUBIR L'ILLUMINATION D'UNE ONDE PLANE INCIDENTE. LE PRINCIPE DE CETTE NOUVELLE METHODE DE CALCUL REPOSE SUR L'EVALUATION NUMERIQUE DE NOUVEAUX PARAMETRES LINEIQUES PROPRES, IMPEDANCES ET ADMITTANCES, QUI TIENNENT COMPTE DES DISCONTINUITES GEOMETRIQUES DU FIL (COUDE, CHANGEMENT DE DIRECTION) ET DES COUPLAGES ENTRE CELLULES MAILLANT LE CONDUCTEUR. CES MATRICES SONT DETERMINEES PAR APPLICATION DU FORMALISME INTEGRAL (RESOLUTION DE L'EQUATION DE POCKLINGTON PAR LA METHODE DES MOMENTS) SUR UN OU PLUSIEURS CONDUCTEURS COMPOSANT LA STRUCTURE. LA DISTRIBUTION DE COURANT SUR L'ENSEMBLE DE LA STRUCTURE MULTIFILAIRE EST ALORS DETERMINEE PAR LA RESOLUTION DES EQUATIONS DES TELEGRAPHISTES PAR LA TECHNIQUE DES VARIABLES D'ETAT. LE FAIT D'INTRODUIRE CES NOUVEAUX PARAMETRES DANS LES MATRICES DES IMPEDANCES ET ADMITTANCES LINEIQUES CONDUIT ALORS A CONSIDERER LA STRUCTURE COMME UNE LIGNE NON-UNIFORME. L'EVALUATION DES CHAMPS RAYONNES, EN ZONE PROCHE OU LOINTAINE, EST ENSUITE OBTENUE DE FACON CLASSIQUE PAR LE THEOREME DE SUPERPOSITION. LA VALIDATION DE CETTE NOUVELLE METHODE EST EFFECTUEE SOIT A PARTIR DE RESULTATS DE MODELISATION ISSUS DU LOGICIEL NEC2D, SOIT PAR CONFRONTATION AVEC DES RESULTATS DE MESURES SUR UNE STRIP-LINE FILAIRE. CETTE CONFIGURATION PERMET, EN PARTICULIER, UNE ETUDE DE L'INFLUENCE DU NOMBRE DE CONDUCTEURS SUR LA PRESENCE DE ZONES HOMOGENES DANS LE VOLUME DE TEST DE LA STRIPLINE.

Book excerpt: “Simplexity, as I understand it, is the range of solutions living organisms have found, despite the complexity of natural processes, to enable the brain to prepare an action and plan for the consequences of it. These solutions are simplifying principles that enable the processing of information or situations, by taking into account past experience and anticipating the future. They are neither caricatures, shortcuts, or summaries. They are new ways of asking questions, sometimes at the cost of occasional detours, in order to achieve faster, more elegant, more effective actions.” A. B. As Alain Berthoz demonstrates in this profoundly original book, simplicity is never easy; it requires suppressing, selecting, connecting, thinking, in order to then act in the best way possible. And what if we, in turn, are inspired by the living world to process the complexity that surrounds us? Alain Berthoz is professor at the Collège de France where he is co-director of the Laboratoire de physiologie de la perception et de l’action. [Laboratory for the physiology of perception and action]. He is a member of the French Academy of Sciences, and is the author of Le Sens du mouvement [The Brain's Sense of Movement] and La Décision [Emotion and Reason].

Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: 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 excerpt: Interest in computer applications has led to a new attitude to applied logic in which researchers tailor a logic in the same way they define a computer language. In response to this attitude, this text for undergraduate and graduate students discusses major algorithmic methodologies, and tableaux and resolution methods. The authors focus on first-order logic, the use of proof theory, and the computer application of automated searches for proofs of mathematical propositions.
