This book was released on 1996 with total page 120 pages. Available in PDF, EPUB and Kindle. Book excerpt: POUR LA REALISATION DES EXPERIENCES SOUTERRAINES (DECROISSANCES DOUBLE BETA, RECHERCHE DE LA MATIERE NOIRE, PROBLEME DES NEUTRINOS SOLAIRES...), AFIN DE DIMINUER LES NIVEAUX DE BRUIT DE FOND IL EST NECESSAIRE DE POUVOIR SELECTIONNER ET CONTROLER LES MATERIAUX DES DETECTEURS POUR LEUR FAIBLE TAUX, VOIRE L'ABSENCE DE CONTAMINATIONS RADIOACTIVES. DANS CE BUT, ON S'EST PARTICULIEREMENT INTERESSE AU DEVELOPPEMENT DE LA SPECTROMETRIE GAMMA BAS BRUIT DE FOND. UN DETECTEUR GERMANIUM PERMETTANT DE MESURER DES ACTIVITES DE L'ORDRE DE 200 MICRO-BQ/KG A ETE REALISE PUIS INSTALLE AU LABORATOIRE SOUTERRAIN DE MODANE. SES PERFORMANCES EN EFFICACITE ET BRUIT DE FOND ONT ETE ANALYSEES TANT DU POINT DE VUE EXPERIEMENTAL QUE PAR SIMULATIONS MONTE CARLO (GEANT). LA SENSIBILITE DE CET OUTIL A AUSSI PERMIS D'ETUDIER LES DECROISSANCES DOUBLE BETA DEUX NEUTRINOS DES ISOTOPES 100MO, 82SE, 96ZR, 106CD, ET 92MO, VERS LES ETATS EXCITES DES ISOTOPES 100RU, 82KR, 96MO, 106PD, ET 92ZR.

Book excerpt: CE TRAVAIL ENTRE DANS LE CADRE DE L'EXPERIENCE NEMO (MISE EN EVIDENCE DE LA DOUBLE DESINTEGRATION SANS EMISSION DE NEUTRINOS DU #1#0#0MO) ET PLUS PARTICULIEREMENT DANS LA SELECTION PAR SPECTROMETRIE DES MATERIAUX NECESSAIRES A LA CONSTRUCTION DU DETECTEUR NEMO3. AFIN D'EVITER D'UNE PART UNE SURCHARGE DES SPECTROMETRES ULTRA BAS BRUIT DE FOND INSTALLES AU LABORATOIRE SOUTERRAIN DE MODANE ET D'AUTRE PART LEUR POSSIBLE POLLUTION PAR UN ECHANTILLON TROP ACTIF, NOUS AVONS DEVELOPPE AU NIVEAU DE LA MER UN SPECTROMETRE GERMANIUM BAS BRUIT DE FOND DONT LES PERFORMANCES PERMETTENT DE MESURER DES ACTIVITES TRES FAIBLES (DE L'ORDRE DE 10 A 20 MBQ/KG EN #2#0#8TL ET #2#2#6RA). LES SENSIBILITES DE MESURE PERMETTENT DE SELECTIONNER ET DE CONTROLER LA TOTALITE DES MATERIAUX DE NEMO3 AVANT UN EVENTUEL ENVOI A MODANE POUR DES MESURES SUPPLEMENTAIRES. POUR ATTEINDRE DE TELS TAUX, UNE ETUDE COMPLETE DES DIFFERENTES COMPOSANTES DU BRUIT DE FOND (RAYONNEMENT COSMIQUE, RAYONNEMENT GAMMA ET NEUTRONS) POUVANT PERTURBER LES MESURES AINSI QUE L'OPTIMISATION DES DIFFERENTS BLINDAGES ONT ETE REALISEES. GRACE A SES TRES BONNES SENSIBILITES DE MESURES, LE SPECTROMETRE GE PEUT EGALEMENT ETRE UTILISE DANS D'AUTRES DOMAINES D'APPLICATIONS TELS QUE L'ENVIRONNEMENT, LA RADIOPROTECTION, ETC.. AFIN D'AMELIORER ENCORE SES PERFORMANCES, UN SYSTEME D'ANTICOMPTON AVEC SCINTILLATEURS PLASTIQUES A ETE ETUDIE, PUIS PROPOSE A LA REALISATION.

Available in PDF, EPUB and Kindle. Book excerpt: Energy density functional (EDF) approaches have become over the past twenty years a powerful framework to study the structure and reactions of atomic nuclei. This book gives an updated presentation of non-relativistic and covariant energy functionals, single- and multi-reference methods, and techniques to describe small- and large-amplitude collective motion or nuclei at high excitation energy. Edited by an expert in energy density functional theory, Dr Nicolas Schunck, alongside several experts within the field, this book provides a comprehensive and informative exploration of EDF methods. Detailed derivations, practical approaches, examples and figures are used throughout the book to give a coherent narrative of topics that have hitherto rarely been covered together.

This book was released on 2013-03-25 with total page 403 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book summarizes the findings and contributions of the European ARTEMIS project, CESAR, for improving and enabling interoperability of methods, tools, and processes to meet the demands in embedded systems development across four domains - avionics, automotive, automation, and rail. The contributions give insight to an improved engineering and safety process life-cycle for the development of safety critical systems. They present new concept of engineering tools integration platform to improve the development of safety critical embedded systems and illustrate capacity of this framework for end-user instantiation to specific domain needs and processes. They also advance state-of-the-art in component-based development as well as component and system validation and verification, with tool support. And finally they describe industry relevant evaluated processes and methods especially designed for the embedded systems sector as well as easy adoptable common interoperability principles for software tool integration.
