Book excerpt: LA 1ERE PARTIE DE CETTE THESE EST CONSACREE A UNE ETUDE THEORIQUE DES PROPRIETES OPTIQUES DES COMPOSES TAL (AL=FE, CO, NI) ET COGA ET DES COMPOSES XPD#3 (X=SC, Y, LA, CE) A L'AIDE D'UN PROGRAMME QUE NOUS AVONS CONSTRUIT DANS LE CADRE DE LA METHODE DES ORBITALES MUFFIN-TIN LINEARISEES (LMTO) ET QUI CALCULE LA PARTIE IMAGINAIRE DE LA FONCTION DIELECTRIQUE AINSI QUE LA CONDUCTIVITE OPTIQUE. L'AVANTAGE DU FORMALISME LMTO EST QU'IL PERMET D'ANALYSER CES FONCTIONS SUIVANT LES CONTRIBUTIONS DES DIFFERENTES SYMETRIES ET DES DIFFERENTES ATOMES ET D'INTERPRETER AINSI L'ORIGINE DES PICS. POUR LA 1ERE SERIE DE COMPOSES LES SPECTRES OPTIQUES CALCULES SONT EN BON ACCORD AVEC CEUX OBTENUS EXPERIMENTALEMENT. DANS LA 2EME SERIE, NOUS AVONS PU INTERPRETER L'ORIGINE DES PICS A BASSE ENERGIE DE LA CONDUCTIVITE OPTIQUE DE CEPD#3. DANS LA 2EME PARTIE DE CETTE THESE NOUS AVONS ETUDIE LES PROPRIETES ELECTRONIQUES ET LA STABILITE RELATIVE DES DIFFERENTES PHASES MAGNETIQUES DES SUPERRESEAUX FE/RU PAR LA METHODE LMTO D'APRES LES PARAMETRES CRISTALLINS OBTENUS EXPERIMENTALEMENT. NOS RESULTATS SONT EN ACCORD AVEC L'EXPERIENCE EN CE QUI CONCERNE L'ETAT FONDAMENTAL FERROMAGNETIQUE DE CES COMPOSES LORSQU'ILS POSSEDENT PLUS DE 4 PLANS DE FER. PAR CONTRE ILS NE PERMETTENT PAS D'EXPLIQUER LA PRESENCE DES PLANS DE FER NON MAGNETIQUES QUI ONT ETE OBSERVES EXPERIMENTALEMENT AUX INTERFACES. ETANT DONNE QUE RU DETRUIT FACILEMENT LE MAGNETISME DE FE DANS LES ALLIAGES FE#XRU#1##X CES PLANS NON MAGNETIQUES DANS LES SUPERRESEAUX FE/RU POURRAIENT ETRE DUS A LA FAIBLE INTERDIFFUSION AUX INTERFACES OBSERVEE DANS LES ECHANTILLONS

Available in PDF, EPUB and Kindle. Book excerpt: LES PROPRIETES PHYSIQUES DES MULTICOUCHES INTERESSENT PLUSIEURS DOMAINES DE LA PHYSIQUE (OPTIQUE, MAGNETISME PAR EXEMPLE). POUR UTILISER CES MULTICOUCHES AU MIEUX IL EST INDISPENSABLE DE BIEN CONNAITRE LA STRUCTURE DES DIFFERENTES COUCHES AINSI QUE LA MORPHOLOGIE DES INTERFACES ENTRE LES COMPOSANTS DE LA MULTICOUCHE. NOUS AVONS ETUDIE DEUX TYPES DE MULTICOUCHES QUI ONT DES STRUCTURES TRES DIFFERENTES: A) DES MULTICOUCHES AMORPHES QUI TROUVENT LEURS APPLICATIONS DANS LE DOMAINE DE L'OPTIQUE INTERFERENTIELLE DE RAYONS X: (MO/SI)#N, (W/SI)#M (PERIODE D'ENVIRON 10 NM), B) DES MULTICOUCHES METALLIQUES MAGNETIQUES DONT LES APPLICATIONS TECHNOLOGIQUES POTENTIELLES SONT PRINCIPALEMENT DANS LE DOMAINE DE L'ENREGISTREMENT VERTICAL A HAUTE DENSITE: (AU/CO)#N (PERIODE D'ENVIRON 2 NM). NOUS PRESENTONS DANS CE TRAVAIL LES RESULTATS DE L'ETUDE PAR MICROSCOPIE ELECTRONIQUE EN TRANSMISSION DE CES MULTICOUCHES OBSERVEES DE FACE ET SUR LA TRANCHE. COMME L'INTERPRETATION DES MICROGRAPHIES D'OBJETS AUSSI MINCES (COUCHE INDIVIDUELLE DE QUELQUES PLANS ATOMIQUES) EST DIFFICILE NOUS AVONS ETUDIE, POUR LES MULTICOUCHES (AU/CO)#N, LA VISIBILITE DES DETAILS SUR LES COUCHES DE COBALT EN FAISANT DE LA SIMULATION D'IMAGES A PARTIR DE MODELES. CES CALCULS PERMETTENT DE RAISONNABLEMENT INTERPRETER LES IMAGES OBTENUES. NOUS AVONS AINSI OBTENU, D'UNE PART, DES INFORMATIONS SUR LA STRUCTURE DE CHAQUE MATERIAU EN PRESENCE, D'AUTRE PART, UNE DESCRIPTION PRECISE DES COUCHES ET DES INTERFACES ENTRE LES DIFFERENTS MATERIAUX

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.

Book excerpt: The Institute for Amorphous Studies was founded in 1982 as the international center for the investigation of amorphous mate rials. It has since played an important role in promoting the und er standing of disordered matter in general. An Institute lecture series on "Fundamentals of Amorphous Materials and Devices" was held during 1982-83 with distinguished speakers from universities and industry. These events were free and open to the public ,and were attended by many representatives of the scientific community. The lectures themselves were highly successful inasmuch as they provided not only formal instruction but also an opportunity for vigorous and stimulating debate. That last element could not be captured within the pages of a book I but the lectures concentrated on the latest advances in the field I which is why their essential contents are he re reproduced in collective form. Together they constitute an interdisciplinary status report of the field. The speakers brought many different viewpoints and a variety of back ground experiences io bear on the problems involved I but though language and conventions vary I the essential unity of the concerns is very clear I as indeed are the ultimate benefits of the many-sided approach.

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?

Available in PDF, EPUB and Kindle. Book excerpt: This advanced text for undergraduate and graduate students introduces mathematical logic with an emphasis on proof theory and procedures for algorithmic construction of formal proofs. The self-contained treatment is also useful for computer scientists and mathematically inclined readers interested in the formalization of proofs and basics of automatic theorem proving. Topics include propositional logic and its resolution, first-order logic, Gentzen's cut elimination theorem and applications, and Gentzen's sharpened Hauptsatz and Herbrand's theorem. Additional subjects include resolution in first-order logic; SLD-resolution, logic programming, and the foundations of PROLOG; and many-sorted first-order logic. Numerous problems appear throughout the book, and two Appendixes provide practical background information.
