MOTIVATION: The genome projects produce a wealth of protein sequences. Theoretical methods to predict possible structures and functions are needed for screening purposes, large-scale comparisons and in-depth analysis to identify worthwhile targets for further experimental research. Sequence-structure alignment is a basic tool for the identification of model folds for protein sequences and the construction of crude structural models. Empirical contact potentials (potentials of mean force) are used to optimize and evaluate such alignments. RESULTS: We propose new scoring schemes based on a contact definition derived from Voronoi decompositions of the three-dimensional coordinates of protein structures. We demonstrate that Voronoi potentials are superior to pure distance-based contact potentials with respect to recognition rate and significance for native folds. Moreover, the scoring scheme has the potential to provide a reasonable balance of detail and ion such that it is also useful for the recognition of distantly related (both homologous and non-homologous) proteins. This is demonstrated here on a set of structural alignments showing much better correspondence of native and model scores for the Voronoi potentials as compared to conventional distance-based potentials.
Co-design is concerned with the joint design of hardware and software making up an embedded computer system [Wol94]. A top down design flow for an embedded system begins with a system specification. If it is executable, it may be used for simulation, system verification or to identify algorithmical bottlenecks. In contrast to other chapters of this book, the specification is not developed in this case study, rather it is given from the beginning. Furthermore we are not concerned with partitioning or synthesis of dedicated HW. Instead we focus on the problem how to find an off-the-shelf micro-controller which implements the desired functionality and meets all specification constraints. If feasible, this is usually much cheaper then using dedicated hardware. This chapter will answer the question of feasibility for a real life problem from automobile industry.
The growing number of production enterprises that use software systems to support the production planning and control (PPC-systems and limited life-time of these systems imply that many enterprises have to decide whether or not an existing PPC-system is worthwhile reengineering. The factores that have an impact on this decision are non-quantifiable. Since the fuzzy-set-theory provides facilities to deal with non-quantifiable variables, a decision-tool based upon a fuzzy model was conceived.
Mit dem Projekt METHPRO werden die Entwicklung und der Einsatz einer Methodik verfolgt, mit deren Hilfe Softwareanwender sowie -anbieter die organisatorischen und technischen Prozesse zur integrierten Planung und Steuerung von Produktion (PPS), Instandhaltung (IPS) und Qualitätsmanagement (QM) gestalten und individuell anpassen können. Der Beitrag zeigt, wie ein objektorientierter Prototyp entwickelt wird, der diese integrierten Prozesse unterstützt.
