Book excerpt: L'OBJECTIF DE CETTE ETUDE EST D'EVALUER LES POTENTIALITES DU TRANSISTOR BIPOLAIRE A HETEROJONCTION (TBH) POUR L'AMPLIFICATION DE PUISSANCE A HAUT RENDEMENT INDISPENSABLE POUR LES SYSTEMES DE RADIOCOMMUNICATIONS MOBILES. APRES LA DESCRIPTION DES MOYENS DE CARACTERISATIONS DE TRANSISTORS DE PUISSANCE DISPONIBLES AU SEIN DU LABORATOIRE, LES DEVELOPPEMENTS DE METHODOLOGIES ET D'OUTILS DE SIMULATION ET D'OPTIMISATION ET DES AMPLIFICATEURS DE PUISSANCE SONT PRESENTES. LES POTENTIALITES DU TBH POUR L'AMPLIFICATION DE PUISSANCE A HAUT RENDEMENT A 1.8 GHZ SONT EVALUEES PAR L'UTILISATION INTENSIVE DES OUTILS D'OPTIMISATION DEVELOPPES. UN MODE DE FONCTIONNEMENT OPTIMAL EN RENDEMENT SPECIFIQUE AU TBH EST DEMONTRE. ENSUITE, LES PERFORMANCES THEORIQUES EN TERMES DE PUISSANCE, DE RENDEMENT ET DE LINEARITE D'UN TRANSISTOR BIPOLAIRE A HETEROJONCTION ET D'UN TRANSISTOR A EFFET DE CHAMP DE DIMENSIONS SIMILAIRES SONT COMPARES. DES VALIDATIONS EXPERIMENTALES POUR UN FONCTIONNEMENT EN MONOPORTEUSE ET EN BIPORTEUSE SONT PRESENTEES. DEUS CONCEPTIONS D'AMPLIFICATEURS A BASE DE TBH EN BANDE L ET S RESPECTIVEMENT EN TECHNOLOGIE HYBRIDE ET MMIC SONT DECRITES DANS CE MEMOIRE. LES MESURES EFFECTUEES SUR L'AMPLIFICATEUR EN TECHNOLOGIE HYBRIDE CONFIRMENT LES POTENTIALITES DU TBH DANS LE DOMAINE DES RADIOCOMMUNICATIONS. EN EFFET, UN RENDEMENT EN PUISSANCE AJOUTEE DE 77% A ETE MESURE POUR UNE FAIBLE POLARISATION DE SORTEI (3,3 V)

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: Throughout the world, the cause and impact of global warming and climate change is being passionately debated. While many claim that a climate crisis is imminent if greenhouse gases are not curbed, others argue that the effects have been overblown. Through objective overviews, primary sources, and full-color illustrations, this title will examine What Is Global Warming and Climate Change? What Are the Consequences of Global Warming? What Are the Controversies Surrounding Global Warming? What Are the Solutions for Global Warming?
