The properties of different microCT systems have been determined by simulations based on GEANT4. We demonstrate the influence of the detector material and the X-ray spectrum on the obtained contrast. Four different detector materials (selenium, cadmium zinc telluride, cesium iodide and gadolinium oxysulfide) and two X-ray spectra (a molybdenum and a tungsten source) have been considered. The spectra have also been modified by aluminum filters of varying thickness. The contrast between different tissue types (water, air, brain, bone and fat) has been simulated by using a suitable phantom. The results indicate the possibility to improve the image contrast in microCT by an optimized combination of the X-ray source and detector material.}, language = {en} } @article{Dachwald2004, author = {Dachwald, Bernd}, title = {Interplanetary Mission Analysis for Non-Perfectly Reflecting Solar Sailcraft Using Evolutionary Neurocontrol}, series = {Astrodynamics 2003 : proceedings of the AAS/AIAA Astrodynamics Conference held August 3 - 7, 2003, Big Sky, Montana / ed. by Jean de Lafontaine. - Pt. 2. - (Advances in the astronautical sciences ; 116,2)}, journal = {Astrodynamics 2003 : proceedings of the AAS/AIAA Astrodynamics Conference held August 3 - 7, 2003, Big Sky, Montana / ed. by Jean de Lafontaine. - Pt. 2. - (Advances in the astronautical sciences ; 116,2)}, publisher = {Univelt}, address = {San Diego, Calif.}, isbn = {0-87703-509-1}, pages = {1247 -- 1262}, year = {2004}, language = {en} } @article{HagemannBreitschuhGraberetal.2004, author = {Hagemann, Hans-J{\"u}rgen and Breitschuh, S. and Graber, S. and Schmitz, G{\"u}nter}, title = {Internet Laboratory Courses with Remote Access and Control of Real Measurements on Sensors and Electronic Components}, series = {Mechatronics \& Robotics 2004 : Aachen, Germany, September 13 - 15, 2004 / [APS - European Centre for Mechatronics].

Seite 1-14 ISBN 3-86068-213-X International Conference on Computing in Civil and Building Engineering <10, 2004, Weimar> Summary In our project, we develop new tools for the conceptual design phase. During conceptual design, the coarse functionality and organization of a building is more important than a detailed worked out construction. We identify two roles, first the knowledge engineer who is responsible for knowledge definition and maintenance; second the architect who elaborates the conceptual de-sign. The tool for the knowledge engineer is based on graph technology, it is specified using PROGRES and the UPGRADE framework. The tools for the architect are integrated to the in-dustrial CAD tool ArchiCAD. Consistency between knowledge and conceptual design is en-sured by the constraint checker, another extension to ArchiCAD.}, subject = {CAD}, language = {en} } @article{FockeMinkForcher2004, author = {Focke, Markus and Mink, Andreas and Forcher, Ralf}, title = {Intelligente Zulaufsteuerung durch Telematikgest{\"u}tzte Transportevents : Konzeption eine Telematikbasierten Supply Chain Event Managements f{\"u}r die Zulaufsteuerung industrieller Produktionsunternehmen / Focke, Markus ; Mink, Andreas ; Forcher, Ralf}, series = {Logistik-Management. 6 (2004), H. 4}, journal = {Logistik-Management. 6 (2004), H. 4}, isbn = {1436-6231}, pages = {47 -- 59}, year = {2004}, language = {de} } @article{StarkeHackel2004, author = {Starke, G{\"u}nther and Hackel, Matthias}, title = {Integrierte Oberfl{\"a}chendigitalisierung f{\"u}r die flexible Automatisierung bei kleinen Losgr{\"o}ßen}, series = {Mechatronics \& robotics 2004 : Aachen, Germany, September 13 - 15, 2004 / [IEEE ...].
