This unique book provides a fully revised and up-to-date treatment of the TTCN-3 language TTCN-3 is an internationally standardised test language with a powerful textual syntax which has established itself as a global, universal testing language. Application of TTCN-3 has been widened beyond telecommunication systems to areas such as the automotive industry, internet protocols, railway signalling, medical systems, and avionics. An Introduction to TTCN-3 gives a solid introduction to the TTCN-3 language and its uses, guiding readers though the TTCN-3 standards, methodologies and tools with examples and advice based on the authors' extensive real-world experience. All the important concepts and constructs of the language are explained in a step-by-step, tutorial style, and the authors relate the testing language to the overall test system implementation, giving the bigger picture. This second edition of the book has been updated and revised to cover the additions, changes and extensions to the TTCN-3 language since the first version was published. In addition, this book provides new material on the use of XML, test framework design and LTE testing with TTCN-3. Key Features: Provides a fully revised and up-to-date look at the TTCN-3 languageAddresses language standardization, tool implementation and applying TTCN-3 in real world scenarios such as VoIP and LTE testingExplores recent advances such as TTCN-3 core language extensions on type parameterization, behavior types, real time and performance testingIntroduces the use of ASN.1 and XML with TTCN-3Written by experts in the fieldIncludes an accompanying website containing code samples and links to the relevant standards documents (www.wiley.com/go/willcock_ttcn-3_2e) This book is an ideal reference for test engineers, software developers, and standards professionals. Graduate students studying telecommunications and software engineering will also find this book insightful.

The development of scalable microfabricated ion traps with multiple segments for the realization of quantum computing is a challenging task in quantum information science. The research on the design, development, fabrication, and operation of the first European micro-trap is shown in this thesis. This chip-based micro-trap is an outstanding candidate towards experiments for a future quantum processor with trapped single ions. In the experiments coherent quantum state manipulation is demonstrated, and sideband cooling to the motional ground state is realized. The heating rate is determined and the applicability for quantum computation is proven. Furthermore planar trap designs are investigated - a planar microparticle trap was built and operated. A linear microfabricated planar trap was operated, showing the proof of concept of a novel designed and fabricated Y-shaped planar trap.

Stephan Schulz entwickelt eine allgemeine Methodik zur Anwendung der kollektiven Entscheidungstheorie auf juristische Probleme bei Abstimmungen und untersucht auf dieser Basis ausgewahlte Rechtsfragen der Beschlussfassung im Aktienrecht. Im Mittelpunkt stehen: das Bestehen und der Umfang positiver Stimmpflichten von Aktionaren, die gerichtliche Inhaltskontrolle von Hauptversammlungsbeschlussen und die ungeschriebenen Zustimmungsrechte der Hauptversammlung.
