Due to the low energy content of the high-voltage traction battery, the range of battery electric vehiclesis currently restricted. Compared to conventional vehicles, the range is significantly lower. Thus, using a battery electric vehicle everyday might result in a complex conflict of objectives between range, dynamic and comfort requirements.For this purpose, this study develops a holistic system approach, in order to implement and apply range-extending functionalities.

Ambitious targets for the use of renewable electricity (RES-E) have been formulated by the EU Commission and the EU Member States. Taking into account technical, economic, and ecological framework conditions of the electricity market in a model-based approach, this book provides a comprehensive, quantitative assessment of the future penetration of renewable electricity in the European electricity market.

Telephone service conversations are a central component of social and economic communication practice. They are to a considerable extent pre-planned and standardized. In addition to the desired positive effects (uniformity, efficiency, customer orientation), established call standards lead to unwanted negative effects such as speaking-linguistic stereotypes, over-marking or automated call handling. These and other phenomena are the object of investigation in the research focus on professional telephony at the Martin Luther University Halle-Wittenberg. The author bundles and systematizes the past research work, extended by own investigations and illustrates exemplary approaches, concepts and concrete measures for optimization of conversations in telephone customer service. Judith Pietschmann completed her PhD at the Martin Luther University Halle-Wittenberg in 2017. As a lecturer in the Department of Speech Science and Phonetics, she teaches and researches in the main areas of oral communication in institutional contexts, qualitative and quantitative speech impact research, prosody in interaction and communicative promotion of competence in professional qualification.

If numeric data from the Web are brought together, natural scientists can compare climate measurements with estimations, financial analysts can evaluate companies based on balance sheets and daily stock market values, and citizens can explore the GDP per capita from several data sources. However, heterogeneities and size of data remain a problem. This work presents methods to query a uniform view - the Global Cube - of available datasets from the Web and builds on Linked Data query approaches.

This work analyses technological least-cost pathways for deep emission reductions in the European power sector. It seeks a better understanding of the role renewable energies play in the transformation process up to 2050. Therefore, a model is developed which optimises capacity expansion and hourly dispatch of both conventional and renewable power generation, transmission grids and storage facilities in all hours of the analysed years. The model is applied to four long-term scenarios.

Is it possible to change the language in a group? And if so, how? In politics and business, conclusive answers to these questions are of great interest. Karolina Suchowolec finds them by analysing the current state of research on language planning, planned languages, controlled languages and terminology work, examining the findings for their possible generalisation and deriving from this language guidance as an overarching linguistic object of research. She has empirically investigated its practical implementation. As a result, she formulates an overview of the challenges of language control as well as the solution approaches postulated in the relevant literature - a solid basis for further theoretical research and support for practical language control. Karolina Suchowolec, *1984, studied Applied Linguistics and German as a Foreign Language in Dresden and earned her doctorate in Linguistics in Hildesheim. As a research assistant at the Institute for German Language in Mannheim, she is involved in terminological and applied linguistic projects. Her research interests include specialist communication, terminology management, controlled languages and knowledge modelling.

The emergence of the Internet of Things (IoT), combined with greater heterogeneity not only online in cloud computing architectures but across the cloud-to-edge continuum, is introducing new challenges for managing applications and infrastructure across this continuum. The scale and complexity is simply so complex that it is no longer realistic for IT teams to manually foresee the potential issues and manage the dynamism and dependencies across an increasing inter-dependent chain of service provision. This Open Access Pivot explores these challenges and offers a solution for the intelligent and reliable management of physical infrastructure and the optimal placement of applications for the provision of services on distributed clouds. This book provides a conceptual reference model for reliable capacity provisioning for distributed clouds and discusses how data analytics and machine learning, application and infrastructure optimization, and simulation can deliver quality of service requirements cost-efficiently in this complex feature space. These are illustrated through a series of case studies in cloud computing, telecommunications, big data analytics, and smart cities.

This book is a collection of contributions to the Special Issue “Historical Acoustics: Relationships between People and Sound over Time”. The research presented here aims to explore the origins of acoustics and examine the relationships that have evolved over the centuries between people and auditory phenomena. Sounds have indeed accompanied human civilizations since the beginning of time, helping them to make sense of the world and to shape their cultures. Several key topics emerged, such as the acoustics of historical worship buildings, the acoustics of sites of archaeological interest, the acoustics of historical opera houses, and the topic of soundscapes as cultural intangible heritage. The book, as a whole, reflects the vibrant research activity around the “acoustics of the past”, which will hopefully be serve as a foundation for inspiring the future path of this discipline.

With the growing emphasis on enhancing the sustainability and efficiency of industrial plants, process integration and intensification are gaining additional interest throughout the chemical engineering community. Some of the hallmarks of process integration and intensification include a holistic perspective in design, and the enhancement of material and energy intensity. The techniques are applicable for individual unit operations, multiple units, a whole industrial facility, or even a cluster of industrial plants. This book aims to cover recent advances in the development and application of process integration and intensification. Specific applications are reported for hydraulic fracturing, palm oil milling processes, desalination, reactive distillation, reaction network, adsorption processes, herbal medicine extraction, as well as process control.

The term “first-principles calculations” is a synonym for the numerical determination of the electronic structure of atoms, molecules, clusters, or materials from ‘first principles’, i.e., without any approximations to the underlying quantum-mechanical equations. Although numerous approximate approaches have been developed for small molecular systems since the late 1920s, it was not until the advent of the density functional theory (DFT) in the 1960s that accurate “first-principles” calculations could be conducted for crystalline materials. The rapid development of this method over the past two decades allowed it to evolve from an explanatory to a truly predictive tool. Yet, challenges remain: complex chemical compositions, variable external conditions (such as pressure), defects, or properties that rely on collective excitations—all represent computational and/or methodological bottlenecks. This Special Issue comprises a collection of papers that use DFT to tackle some of these challenges and thus highlight what can (and cannot yet) be achieved using first-principles calculations of crystals.
