The system requirements specification (SRS) is a highly dynamic document that grows and evolves throughout a software development project, and it is critical that it be carefully engineered and managed. Because the SRS fulfils many roles and is of interest to a diversity of stakeholders, its management should be a collaborative process supported by an(More)
The cross-linking of polymer brushes is studied using the bond-fluctuation model. By mapping the cross-linking process into a two-dimensional (2D) percolation problem within the lattice of grafting points, we investigate the gelation transition in detail. We show that the particular properties of cross-linked polymer brushes can be reduced to the(More)
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)
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)
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)
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)
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)
External-cavity designs satisfy strigent demands Twin trends of higher performance and lower unit price drive rapid growth in spectroscopic applications for tunable, narrow-linewidth diode-laser sources Michael Lang Tunable narrow-linewidth lasers first became commercially available around 20 years ago with the development of etalon-narrowed CW dye lasers(More)
