The two-volume work covers the essential principles of electrical engineering and information technology. Volume 1 essentially focuses on direct-current linear electrical networks and operational amplification circuits, as well as with electrical and magnetic fields. In addition to integrated exercises, the book also contains supplementary practice examples.Das zweibändige Werk behandelt die wichtigsten Grundlagen der Elektrotechnik und Informationstechnik. Band 1 befasst sich im Wesentlichen mit linearen elektrischen Netzen und Operationsverstärkerschaltungen bei Gleichstrom sowie mit elektrischen und magnetischen Feldern und wendet sich an Leser, die mit den Grundbegriffen der Differential- und Integralrechnung vertraut sind; anspruchsvollere Hilfsmittel der Feldtheorie werden im Text erläutert. Band 2 behandelt die Wechselstromlehre einschließlich des Drehstromsystems, die Leitungstheorie, die Maxwellschen Gleichungen, die Fourier-Darstellung von Zeitfunktionen, die Berechnung von Ausgleichsvorgängen mit Hilfe der Laplace-Transformation und die Z-Transformation.

Master's Thesis from the year 2013 in the subject Electrotechnology, grade: 1,0, University of Applied Sciences Regensburg (Fakultät Elektro- und Informationstechnik), language: English, abstract: Virtualization has come a long way since its beginnings in the 1960s. Nowadays, Virtual Machine Monitor (VMM)- or hypervisor-based virtualization of servers is the de facto standard in data centers. In recent years, virtualization has also been adopted to embedded devices such as avionics systems and mobile phones. The first mass deployment of embedded virtualization can probably be seen in video game consoles, though. However, the functionalities and possibilities provided by embedded virtualization today for the most part still are where they were when virtualization was in its infancy in the mainframe era. Moreover, it is still not employed by automotive electronics at all thus far. This thesis presents advancements achieved in hardware virtualization since then as well as their possible merits for embedded virtualization. The emphasis hereby lies on increases in reliability of the resulting embedded systems. Additionally, the focus is on automotive Electronic Control Units (ECUs) and especially the upcoming automotive domain controller architecture. This work is divided into five parts: The first one constitutes an introduction to the problem domain and highlights benefits of virtualizing embedded devices - in particular Domain Controller Units (DCUs), i. e. 'server' variants of ECUs - beyond the mere partitioning into time and space. In the second part, an overview of virtualization technology centered around its basic principles is given. Against this background, complications of virtualizing Input/Output (I/O) operations with current hardware architectures and the adaption of their processors to virtualization are elaborated on. Moreover, the most prominent implications for security as well as requirements and specialties encountered in the context of embedded virtualization are discussed. The third chapter then summarizes embedded virtualization solutions found on today's market. Besides, it details hypervisor techniques resembling the state of the art for servers. In the fourth part, concepts for enhancing reliability - in some aspects also availability - through virtualization and eventually the approach proposed for reliable embedded systems are depicted. Finally, the fifth chapter presents the demonstrator - foremost a technology preview of the latter - built as part of working on this thesis.

Zwischenprüfungsarbeit aus dem Jahr 2002 im Fachbereich Informatik - Allgemeines, Note: 1,7, Hochschule der Medien Stuttgart (Fachbereich Information und Kommunikation), Veranstaltung: Informationstechnik, Sprache: Deutsch, Abstract: Gegenstand der hier vorgestellten Arbeit ist es, das Modell zur Verständnis der Semiotik, nämlich das Semiotische Dreieck von Ogden und Richards von 1923, inhaltlich zu erläutern, sowie dieses Modell und die umfangreichen Zusammenhänge mit Hilfe der Anwendung Flash von Makromedia zu animieren. Mit einer interaktiven Animation soll bewirkt werden, sich umfangreiche Erklärungen in Schriftform zu sparen und sich der Vorteile des Lernens durch Bilder und ergänzende Texte zu bedienen. Die psychologischen Inhalte sollen interaktiv und anschaulich dargestellt werden, dass auch der Laie verstehen kann, was sich dahinter verbirgt und somit die Grundlegende Problematik der Kommunikation an sich verständlicher wird. Die Inhalte sollen dadurch zu einer Verbesserung der Kommunikation und zu mehr Verständnis der einzelnen daraus folgernden Fachgebiete führen. Schlagwörter: Semiotisches Dreieck, Semiotik, Bildsemiotik, Kommunikation Topic of the represented work is the model of the semiotic triangle of Ogden and Richards form 1923, whose contents are illustrated here for a better comprehension, as well as to incite this model and the extensive coherences with Macromedia Flash. With an interactive animation rise is given to avoid extensive explanations in a written form and make case of the advantages of the learning through pictures and completing texts instead.The psychological contents shall be represented in an interactive and vivid way so that even a layman can get the point and that the basic problems of communication can get clearer. Through this the contents shall lead to an improvement of communication and also to more unterstanding of their single subjects. Keywords: semiotic triangle, semiotics, kommunication

Diploma Thesis from the year 2009 in the subject Computer Science - Commercial Information Technology, grade: 2, Fachhochschule des bfi Wien GmbH (Projektmanagement und Informationstechnik), language: English, abstract: The IT Infrastructure Library (ITIL) framework is a defacto standard for a holistic Service Management approach. In its third version a five stage lifecycle model provides principles, roles, processes and functions next to a plurality of information for the history of a service from the cradle to the grave. Preceding activities ensure an efficient implementation of ITIL framework for different kinds of management systems used by IT departments or service providers for small and medium-sized business (SMB). This master thesis reviews the corresponding theory of ITIL and organisational change management as well as project management methods necessary for ITIL framework implementation. Most small and medium-sized businesses rush into the implementation of ITIL framework because an essential analytic planning was not or ineffectually done. The dependences and coherences between the Service Strategy, Service Design, Service Transition, Service Operation as well as Continual Service Improvement allege how to efficiently implement the holistic ITIL framework. Based on a survey of SMBs experiences and level of organisational maturity this information gets combined and framed in an implementation plan in due consideration of all coherences and dependencies to assure optimum quality of implementation. With such a plan, SMBs are in a position to generate as much as possible achievement compared with an adequate scale of effort. SMB has also the assurance that only the appropriate parts of ITIL framework are affected for its System or Service Management approach. The chain of causation starts with a summary of all five ITIL lifecycle stages and its interfaces next to a survey of SMB's experiences with such a framework and level of organisational maturity. It ends with an implementation plan based on the participators statements and adequate project management methods for definition of objectives, pinpointing of dependencies, object and work breakdown structures and environment analysis. My major conclusion of this master thesis is that costs saving characteristics of ITIL framework do not appear by ITIL framework implementation. They appear in case of consistent application.
