Bei der Erprobung prototypischer Antriebsstränge sind präzise Schadensfrüherkennungsmechanismen von höchster Bedeutung. Erwin Brosch deckt die Schwachstellen der heutigen Überwachungsmethodik insbesondere im Hinblick auf die elektrischen Antriebe auf. Im Weiteren zeigt er Optimierungen der Überwachungen und damit auch der Schadensfrüherkennung auf. Es gelingt dem Autor, Erfahrungswerte von Experten in Überwachungen zu transferieren. Trotz des geringen Detailwissens über die prototypischen elektrischen Maschinen kann er eine Methode zur Erstellung von thermischen Simulationen von sich stetig verändernden elektrischen Antriebssträngen erarbeiten. Bei allen gezeigten Methoden werden typische Abläufe und Prozesse bei der Erprobung berücksichtigt.

Climate Change and Circular Economics: Human Society as a Closed Thermodynamic System aims to go beyond the concept of ‘fighting climate change’ to analyze the capacity of human society to evolve in relation to the environment based on a more complex approach. The book stresses the role of resource recovery by innovation in reducing the temperature increase, determined through an irreversible thermodynamic approach. Determining the speed of temperature increase contributed by selected economies and comparing these to environmental recovery time constants shows that emerging economies have a much greater speed and consequently a larger impact on environmental capability to recover.Chapters progress from an analysis of present society as a dissipative open system to a thermodynamics view of the need for a circular economy, a big data analysis of climate change and risk mitigation, economic indicators, including entropy and economics, risk maps of climate change events risks, and insights into the ‘Gibbs paradox’, which describes the connection of two separate systems (like society and environment).

This book analyses issues surrounding the efficient integration of demand response programmes in residential communities. It also explores the benefits and energy efficiency co-ordination corresponding to demand response service in a cooperative system. The author explains how sensors, communication technologies, computational ability, and control can be effectively combined to create a demand planification system. Smart appliances (SAs) and other connected devices, together with smart communities (SCs)¿which enable energy consumers to pursue common goals through cooperation and coordinated behaviour within the framework of the Internet of things (IoT)¿have raised expectations regarding deployment of the information and communication technologies (ICTs) to encourage uptake of demand response (DR) energy efficiency programmes. DR programmes pursue a reduced carbon footprint, balanced supply and demand, and behavioural change in consumers. The book provides sustainable evidence of ICT-supported energy management that can help consumers flexibly manage demand through the formation of sustainable SCs that maximise renewable energy use through large-scale cooperative management mechanisms. SCs cooperating securely in identifying consumption patterns can foster sustainable and efficient energy use, with the outcome of benefits for the participants and for the environment.

Durch den teils massiven Publikumsschwund nach der Pandemie stellt sich die Frage, ob diese als Brandbeschleuniger gewirkt hat für bereits vorhandene Trends. Der Autor geht dem nach anhand der Besuchszahlen bis zur letzten vollständigen vorpandemischen Spielzeit 2018/19. Er zeigt historische Zeitreihen zu Sparten- und Personalentwicklung, Vertriebskanälen und den Einnahmen. Die Theaterstatistik des Bühnenvereins dient vielen Entscheidungsträgern als Grundlage für z.B. kulturpolitische Steuerungen, obwohl sie nicht die komplette deutsche Theaterlandschaft abbildet. Deshalb beleuchtet der Autor weitere Anbieter. Da die Theaterstatistik große kulturpolitische Bedeutung hat, gibt es zum Schluss einige Vorschläge für die Zukunft.
