T1 - A Model Framework Weaving Approach, In: Proceedings of the First Workshop on Models and Aspects - Handling Crosscutting Concerns in MDSD at the 19th European Conference on Object-Oriented Programming (ECOOP 2005) T2 - 19th European Conference on Object-Oriented Programming (ECOOP 2005) N2 - Nowadays, in software development usually various models and description fragments are created. Some of these artifacts describe the core of the application, such as the data model or the user interaction model. Other artifacts describe cross-cutting concerns, such as security or the requirement: “every change of data has to be confirmed by the user, before it is written into the database”. During the development process these artifacts are combined, transformed, and finally implemented manually or even automatically. For instance a designer may combine a model of a dialog component specifying an action, that changes data, with a common description of a generic confirm dialog. The integrated dialog description may be afterwards implemented by a programmer. The manual combination of both artifacts and the transformation of the combined description into code are errorprone and hard to change. Industry basically tests or actually uses two approaches for the combination today: 1. At the level of code and execution Aspect-Oriented Programming (AOP) is used [KLM+97]. An aspect defines a cross-cutting concern and the weaving instructions. A code weaver provides the actual weaving at compile or runtime. 2. At the level of design models and analysis models Model-Driven Software Development (MDSD) is used [KWB03]. A model in MDSD is a first class development artifact. Thus models are significantly more abstract than the implementation of code. However, these models cannot be executed. Hence, a abstract model is transformed into another, typically more detailed. A series of such transformations results in executable code. Thereby, a model transformer or a code generator reads some of the artifacts. The other artifacts and the combination rules are implemented in transformation rules or code generation templates (or somewhere else in the transformation / generation approach).

T1 - Berechnung der Trittschalldämmung von Holzbalkendecken mit Finite Elemente Methoden“ T2 - DAGA Tagunsband N2 - Die vorliegende Arbeit entstand im Rahmen ei nes Forschungsprojekts des Lehrstuhls für Computation in Engineering an der Technische n Universität München in Kooperation mit dem Fraunhofer Institut für Bauphysik, Stuttg art und dem ift Schallschutzzentrum, Rosen- heim. Die primäre Zielsetzung des Forschungsp rojekts lag in der Entwicklung konstruktiver Maßnahmen zur Verbesserung der tieffreque nten Trittschalldämmung von Holzdecken. Zur Entwicklung dieser Maßnahmen war zunächst durch die Klärung der akustischen Wechselwirkungen zwischen Deckenauflage und Rohdecke ein besseres Verständnis für das Schwingungsverhalten der Dec kenaufbauten zu erarbeiten . Um den erheblichen Aufwand einer rein empirischen (messtechnischen) Untersuchung dieser Wechselwirkungen zu re- duzieren, wurde die Entwicklung und Bereitste llung leistungsfähiger Berechnungsmodelle angestrebt. Im Teilprojekt der Technischen Universität München wurde hierzu ein Be- rechnungsmodell auf Basis der Finiten Eleme nte Methode erarbeitet, dessen Validierung anhand von Messergebnissen aus der Datenbank des ift Schallschutzzentrums, Rosenheim erfolgte. Zur Visualisierung der Ergebnisse und einer rationellen Modellerstellung wurde eine graphische Nutzeroberfläche entwickel t. Anhand der numerischen Berechnungen des validierten Modells wurden die Wechselwirkungen der Deckenkomponenten untersucht und optimierte Konstruktionen erarbeitet. Nach der messtechnischen Überprüfung der optimierten Konstruktionen im ift Schallschutzzentrum konnten die Ergebnisse in Form von Konstruktionshilfen für optimierte Au fbauten zusammengestellt werden.

T1 - Calibration-Free Hand-Eye Calibration: A Structure-from-Motion Approach T2 - Joint Pattern Recognition Symposium N2 - The paper presents an extended hand-eye calibration approach that, in contrast to the standard method, does not require a calibration pattern for determining camera position and orientation. Instead, a structure-from-motion algorithm is applied for obtaining the eye-data that is necessary for computing the unknown hand-eye transformation. Different ways of extending the standard algorithm are presented, which mainly involves the estimation of a scale factor in addition to rotation and translation. The proposed methods are experimentally compared using data obtained from an optical tracking system that determines the pose of an endoscopic camera. The approach is of special interest in our clinical setup, as the usage of an unsterile calibration pattern is difficult in a sterile environment.

It extends the popular Iterative Closest Point (ICP) algorithm by estimating a scale factor between the two point sets in every iteration. The presented algorithm is especially useful for the registration of point sets generated by structure-frommotion algorithms, which only reconstruct the 3-D structure of a scene upto scale. LiketheoriginalICPalgorithm,thepresentedalgorithm requires a rough pre-alignment of the point sets. In order to determine the necessary accuracy of the pre-alignment, wehaveexperimentallyevaluatedthebasinofconvergence of the algorithm with respect to the initial rotation, translation, andscale factor between the two point sets.
