Kosteneffiziente und nachhaltige Automobile: Bewertung der realen Klimabelastung und der Gesamtkosten – Heute und in Zukunft
by Martin Zapf Hermann Pengg Thomas Bütler Christian Bach Christian WeindlIn diesem Buch werden für repräsentative Fahrzeuge mit unterschiedlichen Antriebskonzepten Gesamtkosten und Treibhausgasemissionen vorgestellt. Die Gesamtkosten sind zum einen aus Kundensicht, aber auch unabhängig von der nationalen Steuerbelastung ermittelt. Es werden sowohl fossile als auch erneuerbare Energieträger betrachtet. Auf Basis systemtheoretischer Grundlagen und wissenschaftlicher Erkenntnisse zum Klimawandel wird die Vorgehensweise entwickelt. Es kommen beispielsweise folgende Methoden zum Einsatz: Lebenszyklusanalysen, Total-Cost-of-Ownership, CO2-Vermeidungskosten und Verbrauchswerte, die Realverbräuche besser widerspiegeln als Normverbrauchswerte. Letztere sind anhand von Verbrauchsfunktionen (Willans-Ansatz) für unterschiedliche Fahrprofile modelliert. Es wird zudem ein politisches Instrument vorgestellt, mit welchem die Temperaturziele des Abkommens von Paris möglichst treffsicher und kosteneffizient eingehalten werden können.

Systems, Decision and Control in Energy IV: Volume I. Modern Power Systems and Clean Energy (Studies in Systems, Decision and Control #454)
by Artur ZaporozhetsThe concept of "energy" includes methods for obtaining and using various types of energy for the needs of human society. Energy is one of the foundations for the development of modern society. The effectiveness of solving social, economic and technical problems, as well as the anthropogenic transformations of nature, is largely determined by energy production and the scale of energy production.Modern energy is not a separate industry, but it penetrates widely into other areas, in particular, chemical, transport, aerospace, construction, metallurgy, engineering, agriculture, etc. The energy sector is based on complex technical systems that are multicomponent, spatially distributed systems that during their operation are affected to a wide range of design and non-design thermomechanical loading conditions, the effects of aggressive fields and units, unauthorized influences (operator errors, terrorism, sabotage) and can reach various limit states.Complex technical systems are characterized by complex non-linear interactions between their constituent elements, complex chains (scenarios) of cause-effect relationships between hazardous, probabilistic events and processes that occur during their life. These scenarios can be implemented over complex ramified scenario trees.Ensuring the operational reliability, durability and safety of power equipment is a difficult task, which is associated with the organization of the reliability of control over the operation of power plants and ensuring optimal conditions for their operation. In this regard, we can distinguish a whole class of tasks related to the development of control systems, diagnostics and monitoring in the energy industry, which are presented in this book. Of particular relevance now is the use of UAVs in the energy sector.Particular attention must be paid to the environmental consequences of the operation of energy facilities, the main of which is significant environmental pollution in large cities and industrial areas.The development of environmental management information systems is the prerogative of the state, corporations and one of the main directions of the national informatization policy. A clearly debugged system of environmental monitoring gives a general idea of the features of the current ecological state, the main directions of state policy in the field of environmental protection, the use of natural resources and environmental safety. The methodology and hardware-software tools for monitoring the state of the environment presented in the monograph are effective tools for supporting decision-making in managing the environmental safety of the atmosphere during its technogenic pollution.

Control of Fuel Combustion in Boilers (Studies in Systems, Decision and Control #287)
by Artur O. ZaporozhetsThis book examines key issues in improving the efficiency of small and medium power boiler units by adding control systems for the fuel combustion process. The original models, algorithms, software and hardware of the system developed for controlling the fuel combustion process are presented. In turn, the book presents a methodology for assessing the influence of climatic factors on the combustion process, and proposes new methods for measuring the thermophysical characteristics, which require taking into account the concentration of oxygen in the air. The system developed here was implemented on a boiler of the NIISTU-5 type, which is widely used for heat power engineering in Ukraine and other Eastern European countries. Given its scope, the book offers a valuable asset for researchers and engineers, as well as lecturers and graduate students at higher education institutions dealing with heat engineering equipment.
Systems, Decision and Control in Energy IV: Volume IІ. Nuclear and Environmental Safety (Studies in Systems, Decision and Control #456)
by Artur Zaporozhets Oleksandr PopovIn recent years, the scale of environmental hazards has been growing, emergencies occur more often at special facilities, in particular nuclear power, the largest of which was the accident at the Chernobyl nuclear power plant in Ukraine on April 26, 1986. With the advent of nuclear power, it was believed that nuclear power reactors were safe enough, control and monitoring systems, protective screens and trained personnel would guarantee their trouble-free operation. There is also a trend now that nuclear power is "environmentally friendly" because it provides a reduction in greenhouse gas emissions with replacing power plants working on fossil fuels. Some countries, such as the United States, have recently classified nuclear energy as a renewable energy source. Despite this, nuclear power is potentially dangerous due to: - possible accidents at power plants, accompanied by the ejection of radioactive materials into the environment; - ejections of about 250 radioactive isotopes into the environment as a result of the operation of nuclear reactors; - emissions of 85Kr, which changes the electrical conductivity of the atmosphere. This gas behaves like a greenhouse gas in the atmosphere, thereby contributing to anthropogenic climate change on Earth; - pollution of the biosphere with plutonium; - radioactive waste is the most important cause of environmental hazard, which remains unresolved. Civilian nuclear power reactors operating throughout the world annually generate large amounts of low-, medium- and high-level radioactive waste. Radioactive pollution accompanies all parts of the complex production of nuclear energy: the extraction and processing of uranium, the operation of nuclear power plants, the storage and regeneration of fuel, which has a significant impact on the environmental friendliness of nuclear energy. In addition, up to 300 natural and technogenic emergencies are registered annually, as a result of which people die and great economic damage is caused. The main reasons for the occurrence of technogenic accidents and catastrophes and the strengthening of the negative impact due to the occurrence of natural and technogenic emergencies in Ukraine are: obsolete fixed assets, in particular for environmental purposes; large volume of transportation, storage and use of hazardous substances; the emergency state of a significant part of public utility networks; insufficient investment support for the process of introducing the latest resource-saving and environmentally friendly technologies in environmentally hazardous industries, primarily in the metallurgical, chemical, petrochemical and energy sectors; environmental problems associated with significant changes in the state of the geological and hydrogeological environment and caused by the closure of unprofitable mining enterprises and mines; unwillingness of economic subjects to take measures to prevent accidents and catastrophes at high-risk and potentially hazardous facilities.
Remote Instrumentation and Virtual Laboratories
by Sandro Zappatore Norbert Meyer Roberto Pugliese Franco DavoliAccessing remote instrumentation worldwide is one of the goals of e-Science. The task of enabling the execution of complex experiments that involve the use of distributed scientific instruments must be supported by a number of different architectural domains, which inter-work in a coordinated fashion to provide the necessary functionality. These domains embrace the physical instruments, the communication network interconnecting the distributed systems, the service oriented abstractions and their middleware. The Grid paradigm (or, more generally, the Service Oriented Architecture -- SOA), viewed as a tool for the integration of distributed resources, plays a significant role, not only to manage computational aspects, but increasingly as an aggregator of measurement instrumentation and pervasive large-scale data acquisition platforms. In this context, the functionality of a SOA allows managing, maintaining and exploiting heterogeneous instrumentation and acquisition devices in a unified way, by providing standardized interfaces and common working environments to their users, but the peculiar aspects of dealing with real instruments of widely different categories may add new functional requirements to this scenario. On the other hand, the growing transport capacity of core and access networks allows data transfer at unprecedented speed, but new challenges arise from wireless access, wireless sensor networks, and the traversal of heterogeneous network domains. The book focuses on all aspects related to the effective exploitation of remote instrumentation and to the building complex virtual laboratories on top of real devices and infrastructures. These include SOA and related middleware, high-speed networking in support of Grid applications, wireless Grids for acquisition devices and sensor networks, Quality of Service (QoS) provisioning for real-time control, measurement instrumentation and methodology, as well as metrology issues in distributed systems.

Consumer Behaviour and Social Network Sites: The Impact of Negative Word of Mouth (Routledge Focus on Business and Management)
by Sarah ZaraketThis book provides a solid understanding of electronic word of mouth (eWOM) by taking the reader through the process of information diffusion from rumour generation in times of traditional word of mouth (WOM) to negative social eWOM and examining how consumers process it. Consumer Behaviour and Social Network Sites tackles different themes relating to negative eWOM. Drawing on both intensive scientific research and professional examples, it bridges the gap between the academic and professional worlds. The book contrasts negative social eWOM to traditional WOM while discussing the specificities of different social networking sites in diffusing such information. It looks at why and how consumers decide to create, share and react to negative social eWOM, suggesting that there are more reasons than are commonly presumed for consumers to articulate themselves on these platforms. It also provides an appreciation of web users' behaviours with regards to negative social eWOM and how it can alter their decision-making journey. The book concludes with several strategies and key takeaways to deal with and prevent negative social eWOM. Most books on WOM are purely professional and lack the theoretical contextualization of the issue. Moreover, they often provide insights on brand-to-consumer conversation but not consumer-to-consumer (C2C) communication. This short book provides marketing academics, students and practitioners with an important insight into these C2C communications that can potentially be harmful to brands.
