Abstract

Energy markets are already undergoing considerable transitions to accommodate new (renewable) energy forms, new (decentral) energy players, and new system requirements, e.g. flexibility and resilience. Traditional energy markets for fossil fuels are therefore under pressure, while not-yet-mature (renewable) energy markets are emerging. As a consequence, investments in large-scale and capital intensive (traditional) energy production projects are surrounded by high uncertainty, and are difficult to hedge by private entities. Traditional energy production companies are transforming into energy service suppliers and companies aggregating numerous potential market players are emerging, while regulation and system management are playing an increasing role. To address these increasing uncertainties and complexities, economic analysis, forecasting, modeling and investment assessment require fresh approaches and views. Novel research is thus required to simulate multiple actor interplays and idiosyncratic behavior. The required approaches cannot deal only with energy supply, but need to include active demand and cover systemic aspects. Energy market transitions challenge policy-making. Market coordination failure, the removal of barriers hindering restructuring and the combination of market signals with command-and-control policy measures are some of the new aims of policies.The aim of this Special Issue is to collect research papers that address the above issues using novel methods from any adequate perspective, including economic analysis, modeling of systems, behavioral forecasting, and policy assessment.The issue will include, but is not be limited to: Local control schemes and algorithms for distributed generation systems; Centralized and decentralized sustainable energy management strategies; Communication architectures, protocols and properties of practical applications; Topologies of distributed generation systems improving flexibility, efficiency and power quality; Practical issues in the control design and implementation of distributed generation systems; Energy transition studies for optimized pathway options aiming for high levels of sustainability

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

3D printing is rapidly emerging as a key manufacturing technique that is capable of serving a wide spectrum of applications, ranging from engineering to biomedical sectors. Its ability to form both simple and intricate shapes through computer-controlled graphics enables it to create a niche in the manufacturing sector. Key challenges remain, and a great deal of research is required to develop 3D printing technology for all classes of materials including polymers, metals, ceramics, and composites. In view of the growing importance of 3D manufacturing worldwide, this Special Issue aims to seek original articles to further assist in the development of this promising technology from both scientific and technological perspectives. Targeted reviews, including mini-reviews, are also welcome, as they play a crucial role in educating students and young researchers.

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.
