Abstract

Ce rapport propose une contribution au débat sur l’énergie, abordé pour l’essentiel sous l’angle des recherches à conduire pour relever les défis successifs qui se poseront dans les prochaines décennies. Le rôle de la science dans ce débat est d'identifier les voies de recherche qui permettront de faire face au besoin croissant d’énergie, en discernant à l’avance les problèmes scientifiques majeurs qu'il faudra surmonter au prix d'un effort soutenu…

Abstract

Die optimale Lagerung des Patienten ist von entscheidender Bedeutung für den Erfolg einer Bestrahlung. In dieser Arbeit wird ein 2D-3D-Registrierungsverfahren für Hochenergiekontrollaufnahmen entwickelt, das die relevante anatomische Information gezielt herausarbeitet. Virtuelle Projektionsbilder können unter Ausnutzung des 3D-Radonraumes schnell berechnet werden. Die mathematische Entkopplung der Freiheitsgrade ermöglicht eine vollständige und robuste Lagebestimmung innerhalb weniger Sekunden.

Abstract

Enfoca a formação das cidades paulistas criadas junto à antiga Companhia Estrada de Ferro Noroeste do Brasil - atual Novoeste, do início da construção da ferrovia, em 1905, até 1914, data que marca o término da ligação entre Bauru (SP) e Porto Esperança, no atual Mato Grosso do Sul. Nesse período, surgem, a partir das estações, povoados que apresentam certas constantes urbanísticas. Cidades como Lins, Penápolis e Araçatuba merecem análise detalhada. O autor verifica que nelas predominou, desde a sua origem, a lógica da especulação imobiliária e do lucro como base para a vida urbana.

Abstract

The influence of the cell size of mobile communication networks onto the exposure to electromagnetic fields is investigated in this work. The exposure is assessed by means of a radio network planning. In a novel approach the path loss for the coverage and the path loss for the exposure are distinguished. The developed model is applied to different wave propagation models and cell structures. The results are discussed.

Abstract

Nowadays drivers have to get along with an increasing complex visual environment in road traffic. There are not only distractions available within the vehicle, like radio, navigation system and passengers. The environment outside the car becomes also more and more complex. Car drivers’ gaze behaviour while being distracted is studied on the basis of some examples. Furthermore different performance indicators are analysed.

Abstract

Thema der Arbeit ist ein alternatives Anregungskonzept für organische Leuchtdioden, bei dem elektrische Leistung über isolierte Elektroden zugeführt wird. Dabei können Verlustprozesse vermieden werden, die der Entwicklung einer organischen Laserdiode bisher im Weg stehen. Untersucht werden die Ladungsträgerdynamik und die optischen Eigenschaften der Strukturen. Eine praktische Anwendung des Konzepts stellt die transparente organische Leuchtdiode mit kapazitiver Anregung (KapOLED) dar.

Abstract

Als Beitrag zur Entwicklung von Röntgenlinsen liefert diese Arbeit erste Ergebnisse von achromatischen refraktiven Linsen zum Einsatz bei wissenschaftlichen Experimenten an Speicherringen. Es werden achromatische Röntgenlinsen studiert, entwickelt und getestet, die zum einen beim Einsatz an monochromatischen Quellen bei Variation der Energie, zum anderen beim Einsatz an breitbandigen Strahlrohren gebraucht werden.

Abstract

A short introduction to the theory of surface plasmon polaritons (SPPs) is given. The application of the SPPs in on-chip signal processing is discussed. In particular, two concepts of plasmonic modulators are reported, wherein the SPPs are modulated by 40 Gbit/s electrical signals. Phase and Mach-Zehnder modulators employing the Pockels effect in electro-optic organic materials are discussed. A few micro-meter long SPP absorption modulator based on a thin layer of indium-tin-oxide is reported.

Abstract

In this work, an innovative real-time microwave control approach is proposed, to improve the temperature homogeneity under microwave heating. Multiple adaptive or intelligent control structures have been developed, including the model predictive control, neural network control and reinforcement learning control methods. Experimental results prove that these advanced control methods can effectively reduce the final temperature derivations and improve the temperature homogeneity.
