Design and Construction Modifications of Switched Reluctance Machines

Although the design principles of the Switched Reluctance Machines (SRMs) are available in different fragments in numerous bibliography positions, there no exists the complex design procedure of whole drive system taking into account the SR Machine, control system and supply device as well. The hybrid design method for SRM drives with application of new analytical calculation methods, finite element method and simulation models is proposed in this thesis. The calculation/design system is characterised by important effectivity and reliability. The new possibilities in analytical determination of saturation effects and core losses under various modes of control, including sensorless method, are also taken into account. The correctness of the proposed design algorithms are verified by laboratory tests made on three motor prototypes manufactured in industry for concrete application. This dissertation provides the elements indispensable for more accurate and complex analysis and design of drives with switch reluctance motors. The elements of electrical motor and control system design as well as the considerations on the choice of supply device and controller subsystems are jointed in the thesis for final receiving of the design tool for considered industrial drive system

Kampfmittel im Meer – Der Umgang mit Belastungsschwerpunkten

Kampfmittel im Meer stellen aufgrund des von ihnen ausgehenden Risikos für die Bevölkerung und die bereits eintretende Belastung der Umwelt eine enorme Herausforderung dar. Von besonderer Bedeutung sind hierbei Belastungsschwerpunkte wie das Versenkungsgebiet Kolberger Heide. Dieser Beitrag beschreibt mögliche Maßnahmen, um mit solchen Belastungsschwerpunkten umzugehen. Hierzu gehören die Einrichtung von Sperrgebieten, die Etablierung eines Monitoring-Programms, die Durchführung historischer Recherchen sowie technischer Erkundungsarbeiten, die Räumung von Kampfmitteln und an die Öffentlichkeit gerichtete Informationskampagnen. Anschließend wird untersucht, wie diese Maßnahmen bislang in der Kolberger Heide Anwendung finden. Zuletzt werden mögliche zukünftige Maßnahmen vorgeschlagen

World ocean review: Mit den Meeren leben 7. Lebensgarant Ozean – nachhaltig nutzen, wirksam schützen

Im Fokus der siebten Ausgabe des »World Ocean Review« stehen die Auswirkungen des Klimawandels auf die Physik des Meeres und auf seine Lebensgemeinschaften; die Folgen von Fischerei, Schifffahrt, Ressourcenabbau, Energiegewinnung und Meeresverschmutzung sowie die Fragen, wie sich Wirkstoffe aus dem Meer nutzen lassen und wie der Ozean künftig so verwaltet werden kann, dass sowohl sein Schutz als auch die Teilhabe möglichst aller Menschen an seinen Leistungen und Gütern gewährleistet sind
