Because research find ings often do not have direct or immediate relevance to IS professionals in industry , the question arises as to how those findings should be disseminated to them in a suitable form at such time as they do become relevant. A central argument of this paper is that the traditional mechanisms whereby academic researchers disseminate their(More)
In the late 1990's, there was substantial activity within the " Web engineering " research community and a multitude of new Web approaches were proposed. However , numerous studies have revealed major gaps in these approaches, including coverage and interoperability. In order to address these gaps, the Model-Driven Engineering (MDE) paradigm offers a new(More)
The FlexRay bus system is the new de-facto standard for connecting electronic control units (ECUs) in cars. Because of its time-triggered message scheduling, it is regarded as the basis for applications like drive-by-wire. In order to fulfill the associated safety requirements, a reliable membership service is mandatory for providing consensus on all(More)
1 Motivation Newest publications resume the impact of application marketplaces as an arbitra-tive competitive advantage in the market of mobile devices (Laube 2009, p. 8). Neologisms like " App-Mania " (Sandin 2009, p. 1) stand for this evolution on the mobile side. On the PC side other trends in form of Software-as-a-Service or electronic marketplaces and(More)
Large-scale simulations of the swelling of a long N-mer in a melt of chemically identical P-mers are used to investigate a discrepancy between theory and experiments. Classical theory predicts an increase of probe chain size R ∼ P(-0.18) with decreasing degree of polymerization P of melt chains in the range of 1 < P < N(1/2). However, both experiment and(More)
INTRODUCTION There has been considerable speculation of late that the design of hypermedia and Web-based systems warrants new methods different from those used in conventional software design (Kautz & Nørbjerg, 2003). However, much confusion abounds within this debate because fundamental concepts such as hypermedia, multimedia, and Web-based systems are(More)
We consider the problem of quickest detection, i.e. we sequentially monitor a data sequence to detect a shift in the sampling distribution which may occur at an unknown time instance. Conventional quickest detection procedures typically require a-priori knowledge of the underlying pre- and post-change distributions of the process. Such knowledge may not be(More)
To my family I Acknowledgments I would like to thank all people who have supported and inspired me during my doctoral work. I especially wish to thank Prof. Dr.-Ing. Abdelhak Zoubir for supervising this work. It is really an honor and a pleasure to be supervised by an outstanding professor who gave me a highly inspiring mix of freedom in work and research(More)
