Book Description
LES SOURCES MICRO-ONDES DE FORTE PUISSANCE, TYPE VIRCATOR ONT VU LEUR INTERET ACCRU CES DERNIERES ANNEES. ELLES SONT TOUTES BASEES SUR LE MEME PRINCIPE QUI PERMET D'OBTENIR UN RAYONNEMENT MICRO-ONDE A PARTIR DE FAISCEAUX D'ELECTRONS INTENSES. UNE ETUDE GENERALE CONCERNANT LES DIODES, A L'ORIGINE DE L'EMISSION ET DE L'ACCELERATION DES CHARGES, AINSI QUE DES GUIDES D'ONDES DANS LESQUELS SE PROPAGE L'ENERGIE, A ETE ENTREPRISE. DES SIMULATIONS D'EXPERIENCES PROVENANT SOIT DE LA LITTERATURE SOIT DU CESTA ONT ETE FAITES A L'AIDE D'UN CODE PARTICULAIRE ELECTROMAGNETIQUE DU CEA, LE CODE M2V. MAL ADAPTE AU PROBLEME, IL N'A PAS DONNE DE RESULTATS ASSEZ SATISFAISANTS POUR ENVISAGER UNE ETUDE THEORIQUE POUSSEE. UN NOUVEAU CODE PARTICULAIRE ELECTROMAGNETIQUE, LE CODE CODEX A ETE REALISE SUR CRAY T-90 AFIN DE PALLIER A CET INCONVENIENT. TOUTE SON ORIGINALITE RESIDE DANS LE FAIT QUE LES CHAMPS ELECTRIQUES ET MAGNETIQUES SONT CALCULES A PARTIR DES POTENTIELS SCALAIRE ET VECTEUR ET NON DES DENSITES DE CHARGES OU DE COURANT. DE CETTE MANIERE, DES CONDITIONS LIMITES SATISFAISANTES SUR LES CHAMPS ONT PU ETRE IMPOSEES, FACTEUR EXTREMEMENT IMPORTANT POUR UNE BONNE MODELISATION. APRES DE NOMBREUX TESTS DE VALIDATION, CE CODE A PARFAITEMENT RESTITUE DES EXPERIENCES DE TYPE VIRCATOR PROVENANT DU CESTA. IL A MIS EN EVIDENCE UN NOUVEAU PHENOMENE, LE GLISSEMENT DE LA FREQUENCE D'EMISSION. DE PREMIERES ETUDES DE DIMENSIONNEMENT ONT PERMIS DE RELIER LA GEOMETRIE DE LA DIODE A LA FREQUENCE MICRO-ONDE ET LA PUISSANCE QUI EN RESULTE. LE PROJET DEMOM REALISE EN COLLABORATION AVEC LES CEA DE BORDEAUX ET DE VAUJOURS UTILISE UN GENERATEUR EXPLOSIF AU LIEU D'UN GENERATEUR ELECTRIQUE. LE CODE CODEX A SIMULE LES EXPERIENCES, EN METTANT A JOUR UN PROBLEME DE MESURE AU NIVEAU DE LA FREQUENCE D'EMISSION. UNE ETUDE DU COURANT, PAR SA FORME TEMPORELLE, SON INTENSITE, A MONTRE L'INFLUENCE DU COUPLE COURANT-TENSION SUR LES RESULTATS. CE CODE, TRES SATISFAISANT, AIDE A L'ETABLISSEMENT D'UN MODELE ANALYTIQUE SIMPLIFIE, QUI PERMETTRA D'UN COTE, D'AUGMENTER LE RENDEMENT, ASSEZ BAS, D'UNE TELLE SOURCE, ET DE L'AUTRE DE POUVOIR MIEUX SELECTIONNER LA FREQUENCE D'EMISSION.

Book Description
Earthen architecture constitutes one of the most diverse forms of cultural heritage and one of the most challenging to preserve. It dates from all periods and is found on all continents but is particularly prevalent in Africa, where it has been a building tradition for centuries. Sites range from ancestral cities in Mali to the palaces of Abomey in Benin, from monuments and mosques in Iran and Buddhist temples on the Silk Road to Spanish missions in California. This volume's sixty-four papers address such themes as earthen architecture in Mali, the conservation of living sites, local knowledge systems and intangible aspects, seismic and other natural forces, the conservation and management of archaeological sites, research advances, and training.

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.
