Investigation of new approaches
ISBN: 9786203579895 / Angielski / Miękka / 140 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. The objective of this study is to investigate new approaches that may overcome the issuesof phase separation and high dislocation density in InxGa1-xN materials with high indiumconcentration, for the realization of high efficiency InxGa1-xN based solar cells.Two novel approaches are proposed that may overcome the basic challenges involvedin the InxGa1-xN heterojunction solar cells. The first approach consists in the growthof a thick multi-layered InGaN/GaN absorber, called Semibuk approach. These GaNinterlayers need to be thick enough to be effective and thin enough to allow carrier...

Identifizierung und Analyse von Stakeholdern im Kontext von Wäldern
ISBN: 9786202848404 / Niemiecki / Miękka / 108 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. Die Abholzung der Naturwälder in den Bergregionen Pakistans ist eines der schwerwiegendsten Umweltprobleme. Obwohl zahlreiche Entwicklungs- und Erweiterungsprojekte zum Schutz und zur Entwicklung der Wälder durchgeführt werden, ist die Rate der Waldvernichtung in Pakistan immer noch sehr hoch. Da die forstbezogenen Projekte ihre angestrebten Ziele nicht erreichen, müssen die Ursachen für die Ineffektivität dieser Projekte untersucht werden. Daher zielte die Studie darauf ab, die Rollen und Interaktionen der Beteiligten zu analysieren, d.h. der ausführenden Stellen, der Geberagenturen,...

L'épuisement des forêts naturelles dans les zones montagneuses du Pakistan est l'un des problèmes environnementaux les plus graves. Malgré la mise en oeuvre de nombreux projets de développement et d'extension pour protéger et développer les forêts, le taux d'épuisement des forêts est encore très élevé au Pakistan. L'échec des projets liés aux forêts à atteindre les objectifs prévus exige que l'on étudie les causes de l'inefficacité de ces projets. Ainsi, l'étude visait à analyser les rôles et les interactions des parties prenantes, à savoir les agences de mise en...

User Selection and Scheduling Algorithms for MIMO-BC Systems
ISBN: 9783639662597 / Angielski / Miękka / 2014 / 172 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. This book investigates the problem of user selection and scheduling in MIMO-BC. A low-complexity user selection algorithm is proposed when the BS has perfect channel-state information and the performance of the proposed algorithm with linear and non-linear precoding techniques is evaluated. A signalling scheme for the MIMO-BC systems in the absence of perfect CSIT is presented. A novel transmit-antenna selection scheme is proposed. The performance of the proposed scheme with different user selection algorithms and linear receivers is evaluated. The book considers a cross-layer scheduling...
