To ensure high quality and to avoid misunderstandings, the requirements have to be validated. Because of the ambiguity of natural language and the resulting absence of an automatic mechanism, this has to be done manually. Such manual validation techniques are timeconsuming, error-prone, and repetitive because hundreds or thousands of requirements must be checked. With an automatic validation the requirements engineering process can be faster and can produce requirements of higher quality. To realize an automatism, we propose a controlled natural language (CNL) for the documentation of requirements. On basis of the CNL, a concept for an automatic requirements validation is developed for the identification of inconsistencies and incomplete requirements. Additionally, automated correction operations for such defective requirements are presented. The approach improves the quality of the requirements and therefore the quality of the whole development process.}}, author = {{Holtmann, Jörg and Meyer, Jan and von Detten, Markus}}, booktitle = {{2011 IEEE Fourth International Conference on Software Testing, Verification and Validation Workshops}}, isbn = {{9781457700194}}, title = {{{Automatic Validation and Correction of Formalized, Textual Requirements}}}, doi = {{10.1109/icstw.2011.17}}, year = {{2011}}, } @inproceedings{20960, abstract = {{Heutige Steuergeraete im Automobilbereich zeichnen sich durch eine hohe Funktionsvielfalt und eine hohe Vernetzung untereinander aus.

Several tools help to identify implementations of software patterns, e.g. Design Patterns, in source code and thus help to reveal the underlying design. In case of the reverse engineering tool suite Reclipse, detection algorithms are generated from manually created, formal pattern specifications. Due to numerous variants that have to be considered, the pattern specification is error-prone. Because of this, the complex, step-wise generation process has to be traceable backwards to identify specification mistakes. To increase the traceability, we directly interpret the detection algorithm models (story diagrams) instead of executing code generated from these models. This way, a reverse engineer no longer has to relate generated code to the story diagrams to find mistakes in pattern specifications. }}, author = {{Fockel, Markus and Travkin, Dietrich and von Detten, Markus}}, booktitle = {{Proceedings of the 8th International Fujaba Days}}, title = {{{Interpreting Story Diagrams for the Static Detection of Software Patterns}}}, year = {{2011}}, } @inproceedings{17420, abstract = {{Occlusion culling is a common approach to accelerate real-time rendering of polygonal 3D-scenes by reducing the rendering load. Especially for large scenes, it is necessary to remove occluded objects to achieve a frame rate that provides an interactive environment. In order to benefit from the culling properly, often hierarchical data structures are used. These data structures typically create a spatial subdivision of a given scene into axis-aligned bounding boxes. These boxes can be tested quickly, but they are not very precise. By using these boxes, the included objects are detected as visible, even if other objects occlude them (false-positives). To get perfect results, the models’ original geometry included in the box has to be tested, but this would require too much computational power. To overcome this problem, original objects’ approximations could be used, but typical methods for mesh simplification cannot be applied, because they do not create an outer hull for a given object. We present a model simplification algorithm, which generates simple outer hulls, consisting of only few more triangles than a box, while preserving an object’s shape better than a corresponding bounding box. This approach is then extended to a hierarchical data structure, the so-called hull tree, that can be generated for a given scene to improve the visibility tests. Next, we present an approximative rendering algorithm, which combines the features of the hull tree with the use of inner hulls for efficient occlusion detection and global state-sorting of the visible objects. }}, author = {{Suess, Tim and Koch, Clemens and Jähn, Claudius and Fischer, Matthias}}, booktitle = {{Proceedings of the Graphics Interface 2011 Conference, May 25-27, St. John's, Newfoundland, Canada}}, editor = {{Brooks, Stephen and Irani, Pourang}}, pages = {{79----86}}, publisher = {{Canadian Human-Computer Communications Society}}, title = {{{Approximative occlusion culling using the hull tree}}}, year = {{2011}}, } @inproceedings{17421, author = {{Klaas, Alexander and Laroque, Christoph and Dangelmaier, Wilhelm and Fischer, Matthias}}, booktitle = {{Proceedings of the 2011 Winter Simulation Conference (WSC)}}, isbn = {{9781457721090}}, title = {{{Simulation aided, knowledge based routing for AGVs in a distribution warehouse}}}, doi = {{10.1109/wsc.2011.6147883}}, year = {{2011}}, } @inproceedings{17450, author = {{Suess, Tim and Jähn, Claudius and Fischer, Matthias and Meyer auf der Heide, Friedhelm and Koch, Clemens}}, booktitle = {{Augmented & Virtual Reality in der Produktentstehung}}, pages = {{185----197}}, publisher = {{Verlagsschriftenreihe des Heinz Nixdorf Instituts}}, title = {{{Ein paralleles Out-of-Core Renderingsystem für Standard-Rechnernetze}}}, volume = {{295}}, year = {{2011}}, } @phdthesis{17454, author = {{Suess, Tim}}, title = {{{Parallel Real-Time Rendering using Heterogeneous PC Clusters}}}, year = {{2011}}, } @inproceedings{1891, author = {{W.
