Both methods have been compared in terms of accuracy and computational effort. It is shown that they give comparable results if all numerical parameters are controlled carefully. LBM requires a much higher computational effort, however, in contrast to ASD it is able to simulate partially sintered agglomerates as well. The results show that even a very small amount of sintering leads to a significant reduction in the drag force. The analysis of the drag force on agglomerates as well as on aggregates shows that there is no simple geometric quantity which is uniquely related to the drag force. Moreover, there is a significant variation in drag force for single aggregates at different orientations or for the orientation averaged drag force of different aggregates of the same size. This is explained by the structural effects which may lead to a variation in the drag force up to +-20%.}}, author = {{Binder, Christian and Feichtinger, Christian and Schmid, Hans-Joachim and Thürey, Nils and Peukert, Wolfgang and Rüde, Ulrich}}, issn = {{0021-9797}}, journal = {{Journal of Colloid and Interface Science}}, number = {{1}}, pages = {{155--167}}, title = {{{Simulation of the hydrodynamic drag of aggregated particles}}}, doi = {{10.1016/j.jcis.2006.04.045}}, volume = {{301}}, year = {{2006}}, } @article{26148, abstract = {{Die Modellierung der wandnahen Bereiche bei der Simulation von Zweiphasenströmungen spielt in der Praxis eine entscheidende Rolle, wenn erwünschter oder unerwünschter Transport der dispersen Phase zu einer Oberfläche bedeutend ist.

Our algorithm is a variant of KMHybrid [28, 20], i.e. it uses a combination of Lloyd-steps and random swaps, but as a novel feature it uses coresets to speed up the algorithm. A coreset is a small weighted set of points that approximates the original point set with respect to the considered problem. The main strength of the algorithm is that it can quickly determine clusterings of the same point set for many values of k. This is necessary in many applications, since, typically, one does not know a good value for k in advance. Once we have clusterings for many different values of k we can determine a good choice of k using a quality measure of clusterings that is independent of k, for example the average silhouette coefficient. The average silhouette coefficient can be approximated using coresets.To evaluate the performance of our algorithm we compare it with algorithm KMHybrid [28] on typical 3D data sets for an image compression application and on artificially created instances. Our data sets consist of 300,000 to 4.9 million points. We show that our algorithm significantly outperforms KMHybrid on most of these input instances. Additionally, the quality of the solutions computed by our algorithm deviates less than that of KMHybrid.We also computed clusterings and approximate average silhouette coefficient for k=1,…,100 for our input instances and discuss the performance of our algorithm in detail.}}, author = {{Frahling, Gereon and Sohler, Christian}}, booktitle = {{Proceedings of the twenty-second annual symposium on Computational geometry - SCG '06}}, title = {{{A fast k-means implementation using coresets}}}, doi = {{10.1145/1137856.1137879}}, year = {{2006}}, } @inproceedings{18351, abstract = {{In this paper the ideas of a new research project are presented.

Linear ultrasonic motors in contrast have only found limited applications. The main reason for the limited range of application of these very attractive devices seems to be their small force and power range. Attempts to build linear ultrasonic motors for high forces and high power applications have not been truly successful yet. To achieve larger force and higher power, multiple miniaturized motors can be combined. This approach, however, is not as simple as it appears at first glance. The electromechanical behaviour of the individual motors differs slightly due to manufacturing and assembly tolerances. The individual motor characteristics are strongly dependent on the driving parameters (frequency, voltage, temperature, pre-stress, etc.) and the driven load and the collective behaviour of the swarm of motors is not just the linear superposition of the individual drive's forces. Thus, the bundle of motors has to be synchronized and controlled appropriately in order to obtain an optimized drive that is not oversized and costly. We have investigated driving and control strategies of a set of linear ultrasonic motors. Our contribution will be divided into three main parts. In part I ultrasonic linear motors will be introduced. In part II driving strategies for a single motor as well as for a bundle of motors will be presented. These concepts will be verified by simulation results and experimental data. In part III a simplified model for the motor's electromechanical behaviour will be given.}}, author = {{Mracek, Maik and Hemsel, Tobias}}, issn = {{0041-624X}}, journal = {{Ultrasonics}}, keywords = {{Ultrasonic linear motor}}, pages = {{e597 -- e602}}, title = {{{Synergetic driving concepts for bundled miniature ultrasonic linear motors}}}, doi = {{10.1016/j.ultras.2006.05.201}}, volume = {{44, Supplement}}, year = {{2006}}, } @inbook{9551, abstract = {{Friction occurs in the contact between tyre and road. The friction of rubber material on dry surfaces is dominated by hysteresis and adhesion effects. Hysterisis friction is characterised by the energy dissipation within the visco-elastic material, which is caused by its deformation while passing the surface roughness. Hysteresis effects are modelled by an extended linear visco-elastic material with several Maxwell elements. The development of a model in the time domain allows to consider nonlinear effects. Additionally temperature effects are taken into account based on the WLF-transformation. Adhesion forces originate from molecular bindings between the contact partners. This effect is simulated by applying a modified model of Achenbach on real surfaces. The temperature distribution within the friction contact region is investigated experimentally as well. Furthermore global stick-slip vibrations of a rubber block element are investigated using a global contact model.
