Book excerpt: DANS LES SEMICONDUCTEURS A LARGEUR DE BANDE INTERDITE DIRECTE, LES PROCESSUS DE REABSORPTION DU PHOTON EMIS, SONT CONNUS POUR LEUR CONTRIBUTION A L'AUGMENTATION DE LA DUREE DE VIE ET DE LA DIFFUSION DES PORTEURS MINORITAIRES DANS LE CAS D'UNE CELLULE SOLAIRE PUISQU'ILS CONTROLENT LE RENDEMENT PHOTOVOLTAIQUE. LA REABSORPTION EST LIEE A LA STRUCTURE DE BANDE DU SEMICONDUCTEUR DE BASE UTILISE DANS LA FABRICATION DE PHOTOPILES. LA MESURE DU DECLIN DE PHOTOLUMINESCENCE EST UN DES MOYENS QUI PERMET D'EVALUER LA DUREE DE VIE DES PORTEURS MINORITAIRES. IL EN RESULTE QU'UNE BONNE MODELISATION DU DECLIN DE CETTE PHOTOLUMINESCENCE EST NECESSAIRE POUR EVALUER DE FACON PRECISE LA DUREE DE VIE ET LES PARAMETRES DE TRANSPORT. AINSI, NOUS NOUS SOMMES INTERESSES A UNE ETUDE THEORIQUE DETAILLEE DES MECANISMES RELIES A LA STRUCTURE DE BANDE DE CES MATERIAUX ET POUVANT INFLUENCER LA DECROISSANCE DE LUMINESCENCE, EN PARTICULIER LA REABSORPTION QUI JUSQU'ICI N'A PAS BIEN ETE PRISE EN COMPTE DANS TOUTES LES CONFIGURATIONS EXPERIMENTALES. NOUS AVONS RESOLU LE PROBLEME POUR LES DEUX CAS PRATIQUE D'INJECTION: LE CAS LINEAIRE, LIE AUX FAIBLES NIVEAUX D'INJECTION ET LE CAS NON LINEAIRE, LIE AUX FORTES INJECTIONS. CE MODELE DYNAMIQUE TIENT COMPTE DES CONDITIONS EXPERIMENTALES NOTAMMENT DES CARACTERISTIQUES GEOMETRIQUES ET OPTIQUES DE L'ECHANTILLON AINSI QUE DES CARACTERISTIQUES TEMPORELLES DE L'EXCITATION. LES RESULTATS AINSI OBTENUS ONT MONTRE QUE NOTRE MODELE AMELIORE L'ANALYSE DES DONNEES EXPERIMENTALES FOURNIES PAR LA CARACTERISATION. L'AJUSTEMENT GLOBAL ENTRE LES EXPERIENCES ET LE CALCUL PERMET DE DETERMINER LES PARAMETRES DE TRANSPORT TELS LE COEFFICIENT DE DIFFUSION, LES VITESSES DE RECOMBINAISON INTERFACIALES AUSSI BIEN QUE LA DUREE DE VIE NON-RADIATIVE DES PORTEURS MINORITAIRES, ET CE BIEN QUE L'EXPERIENCE SOIT PUREMENT OPTIQUE

Available in PDF, EPUB and Kindle. Book excerpt: This report provides the most comprehensive and rigorous analysis of Iraqi income and expenditure in several decades. The report makes extensive use of the Iraq Household Socio-Economic Survey, the first nationwide income and expenditure survey since 1988. IHSES data is complemented income and expenditure data from a wide range of other measures of living standards, allowing us to analyze living standards in a holistic way. The analysis presented here was performed with two main goals first, to inform the Government s Poverty Reduction Strategy; and second, to serve as a baseline for future assessments of changes in living standards and the identification of critical issues for deeper examination. Iraqi living standards have two unusual characteristics. First, they have fallen over the past generation. Second, they feature surprisingly little inequality. These characteristics are both rooted in Iraq s recent history of authoritarian government, war, military occupation, insurgency, and civil strife leading to infrastructure destruction and population displacement. There have been few opportunities for individuals to prosper from professional or entrepreneurial activities. Decades of neglected investment have resulted in deterioration of social services and economic infrastructure. Consequently, individuals have lacked capabilities to prosper and an investment climate conducive to prosperity. School enrollment and life expectancy have declined. Extremely low returns to education reflect the combination of poor educational quality and lack of employment opportunities. In terms of economic infrastructure, access to reliable electricity and water, and even access to paved roads are low, are further reflections of decades of neglect. While the upper end of the distribution has been pulled down by a lack of opportunities, the lower end has been supported by direct government provision of food. The Public Distribution System (PDS) provides 85 percent of food needs. While PDS has been useful as a safety net for the poor and the vulnerable, the system is expensive, inefficient, and fiscally risky. Indeed, PDS food rations account for a far greater share of public spending than does education or health. Going forward, Iraq faces two main challenges. First, although Iraq does not have to develop from scratch, it faces a formidable challenge in re-development. Second, a shift by the Government is required from direct provision of basic subsistence toward investment in human capacities. The Government can provide an enabling environment through investments in economic infrastructure and services to business and citizens, thus allowing the population to make productive use of education and their own labor. Both challenges are now being taken up by the Poverty Reduction Strategy, which articulates a detailed set of required actions and outlines priorities for government spending.

Book excerpt: From environmental management to land planning and geo-marketing, the number of application domains that may greatly benefit from using data enriched with spatio-temporal features is expanding very rapidly. This book shows that a conceptual design approach for spatio-temporal databases is both feasible and easy to apprehend. While providing a firm basis through extensive discussion of traditional data modeling concepts, the major focus of the book is on modeling spatial and temporal information.
