Functions, which can be summarized to the keyword Internet Protocol Television (IPTV) describe the transmission of video services to users via Internet Protocol (IP). Accompanying to this new television transmission path Home Theatre PCs (HTPC) running a so called Media Center platform are more and more entering the living rooms as a companion for the popular LCD and Plasma displays. Perfect ease of use and the visual integration on the screen and also into the living room is raising their acceptance. These HTPCs are a central node for multimedia services such as TV, radio and email within the networked household. Thus, there are good preconditions for the use of a HTPC as end device for Telco operator driven IPTV and telecommunication services. In the context of this diploma thesis possibilities for the provisioning of IPTV and Next Generation Network (NGN) services on a converged multimedia home entertainment platform for the living room will be investigated, especially Vista Media Center platforms. For this reason, standardization activities will be investigated, which deal with the integration of IPTV and telecommunication services into NGN. The validation of the results will be achieved by the design and implementation of a Vista Media Center Add-In, which can be integrated as an IP Multimedia Subsystem (IMS) based User Agent (UA) in ETSI TISPAN Release 2 IPTV infrastructures. Additionally, a Cross Domain messaging service for IMS based UA is created, which enables a cross-network communication between users.
The objective of this diploma thesis is to analyse the results of functional tests carried out on hydraulic valve blocks at Wujin Plant of Bosch Rexroth (Chang-zhou) Co., Ltd., (China). Based on this analysis, tests could be checked for systematic errors and root causes of failures be identified. Finally, this helped i n-crease the first pass yield of testing to release resources so far bound in inefficient testing processes. Furthermore, a tracking mechanism was established to monitor the function of crucial sensors at test benches.
The following thesis contains a detailed business plan of a formula student combustion racecar. This includes the evaluating of existing knowledge about the car combined with required information about the market and seed capital. Subsequently the already presented plan is described with the interpretation for future business plans. In this connection the acceptance of electro mobility shall be evaluated and first ideas for the presentation of an electric car shall be created.
The H.323 umbrella standard describes audiovisual communication over packetswitched networks. This thesis illustrates the standard in detail with regards to architecture and implementation. The second part of this dissertation is dedicated to examining the Gmail Voice and Video plug-in, an Internet-based audiovisual communication platform. In the course of this thesis a secured kiosk environment for the Gmail Voice and Video plug-in is being developed.
This thesis looks at Customer Relationship Management in a different way. In order to identify factors that influence the acceptance of one of its components – the analytical CRM – it focuses on theopinion of the company’s employees. The objective of this thesis is to identify factors that positvely influence the acceptance of analytical Customer Relationship Management within organizations.
This thesis work is focusing on the optimization and improvement of IP network and IP transit operations and strategy as well as service offerings. Therefore, this thesis tries to give suggestions at different areas of engineering, business, strategy and operational contexts. This thesis is written in English, as this topic itself is mainly handled in English language too. The first part will try to identify and evaluate methods which are helpful to improve the practical work which will be focused in the second part of this work.
Die vorliegende Diplomarbeit befasst sich mit der Analyse, Auswertung und Empfehlung einer Berechnungsmethode für die axiale Klemmkraft und Wellenmuttern-Anzugsmoment bei Hochgenauigkeits-Axial-Schrägkugellagern für Gewindetriebe. Des Weiteren wird der Einfluss der Klemmkraft bzw. WellenmutternAnzugsmomentes auf unterschiedliche Lagersätze und –anordnungen überprüft und Korrekturfaktoren dafür erarbeitet
Die vorliegende Arbeit befasst sich mit der Leistungsmessung während der Strategieentwicklung im Bereich des Einkaufs am Beispiel DANIELI Österreich. Das Hauptziel ist es, dass System von Danieli Österreich darzustellen, um ein Verständnis der Leistungsmessung in der Praxis zu generieren. Die draus erworbenen Kenntnisse sollen weiterführend in einer Analyse dazu dienen, um die tatsächlichen Einsparung in diesen Ländern aufzuzeigen. Aufgrund Vorgaben der Geschäftsführung ist DANIELI Österreich gezwungen 20% seines Einkaufsvolumens im ehemaligen Jugoslawien einzukaufen, weshalb Möglichkeiten sowie Risiken in den Ländern Bosnien und Herzegowina, Serbien und Kroatien dargestellt werden, um die Einkaufsstrategie zu optimieren.
The Infinica product suite consists of multiple individual microservice applications, mainly gathered around Infinica Process Engine which allows the execution of highly individualised process definitions. For estimating process performance, a layered queuing network approach has been applied. In the first step this required the implementation of a basic modelling framework. Subsequently the implemented framework was used to evaluate the applicability of the approach by creating two models and comparing them with actual performance measurements. Although the calculated results deviated from the expected results, analysis showed that the differences may
derive from an inaccurate model. Nevertheless the general approach seems to be appropriate for the given application as well as for microservices in general, especially when extended with advanced modelling techniques, as the analysed modelled results appear consistent.

This diploma thesis discusses interoperability problems between certified RFID readers and transponders based on the ISO/IEC14443 standardand the root cause for them.
The main goal is the definition of new test methodsand parameters that can supplement the existing test regime for such systems and allowthe identification of those problems beforehand.
