Die weltweit steigenden Investitionskosten in der Elektromobilität und die damit einhergehenden gesellschaftlichen Veränderungen müssen für eine kollektive Akzeptanz der Bevölkerung zu einer verbesserten Ökobilanz beitragen. Emissionsanalysen elektrifizierter Antriebslösungen werden zunehmend kritisch hinterfragt und weichen Life Cycle Assessments (LCAs), die die gesamte Wertschöpfungskette untersuchen. Das Ziel eines nachhaltigen Antriebs harmonisiert mit einem langlebigen und ressourcenschonenden Design, bei dem sich Emissionen während der Fertigung und Entsorgung über den gesamten Lebenszyklus amortisieren. Aufgrund steigender elektrischer und thermischer Belastungen wird das Isolationssystem zunehmend zum bestimmenden Faktor der Lebensdauer elektrischer Maschinen. In der vorliegenden Dissertation wird daher die Forschungsfrage untersucht, in welchem Maß das elektrische Isolationssystem die Lebensdauer und die Zuverlässigkeit einer elektrischen Maschine steigert. Zusätzlich werden die Auswirkungen des Isolationssystems auf die Performance der Maschine berücksichtigt, die sich aus einem veränderten Kupferfüllfaktor und einer optimierten Kühlung ergeben können.

This open access book describes marked advances in imaging technology that have enabled the visualization of phenomena in ways formerly believed to be completelyimpossible. These technologies have made major contributions to the elucidation of the pathology of diseases as well as to their diagnosis and therapy. The volume presents various studies from molecular imaging to clinical imaging. It also focuses on innovative, creative, advanced research that gives full play to imaging technology inthe broad sense, while exploring cross-disciplinary areas in which individual research fields interact and pursuing the development of new techniques where they fuse together. The book is separated into ...
An expanded and updated edition of a comprehensive presentation of the theory and practice of model checking, a technology that automates the analysis of complex systems. Model checking is a verification technology that provides an algorithmic means of determining whether an abstract model—representing, for example, a hardware or software design—satisfies a formal specification expressed as a temporal logic formula. If the specification is not satisfied, the method identifies a counterexample execution that shows the source of the problem. Today, many major hardware and software companies use model checking in practice, for verification of VLSI circuits, communication protocols, software...
