it's OWL ReSerW successfully completed:
Intelligent communication between processes, a significant reduction of consumed resources and utilization of new gripping technology: these are the results of the project "Ressourceneffiziente selbstoptimierende Großwäscherei" (ReSerW), which have been realized by Kannegiesser and four research institutions within the leading edge cluster it's OWL. During the final presentation on April 27, all partners expressed their satisfaction with the outcome of the joint project.

The results were obtained by close cooperation between Kannegiesser and the research institutions CITEC (University of Bielefeld), the Institute for Industrial Mathematics (Paderborn University), the Heinz Nixdorf Institut (Paderborn University), and the Fraunhofer Institute for Mechatronic design. Dirk Littmann, managing director of Kannegiesser, reported on the advances in the development of industrial laundries with respect to productivity, quality, flexibility, and energy efficiency. Using intelligent communication and mathematical optimization techniques, a significant reduction of the consumed resources could be realized during the last years. According to Littmann, the required amount of water per kg laundry could be reduced from ten to three liters, the energy consumption from 2 kWh to 0,8 kWh, and the amount of washing detergents could be reduced by 50 percent.

Prof. Dr. Jens Starke (TU Denmark): "Multiscale analysis of the macroscopic behaviour of particle models" (20.11.2014, 11 Uhr, Room O 1.258)
On November 20th, Jens Starke from TU Denmark will be giving a talk about "Multiscale analysis of the macroscopic behaviour of particle models ".

Abstract: A numerical multiscale approach called equation-free analysis is in the framework of slow-fast dynamical systems further improved and applied to particle models. The method allows to perform numerical investigations of the macroscopic behavior of microscopically defined systems including continuation and bifurcation analysis on the coarse or macroscopic level where no explicit equations are available. This approach fills a gap in the analysis of several complex real-world applications including particle models with intermediate number of particles where the microscopic system is too large for direct investigations of the full system and too small to justify large-particle limits. An implicit equation-free method is presented which reduces numerical errors of the analysis considerably. It can be shown, that the implicitly defined coarse-level time stepper converges to the true dynamics on the slow manifold. The method is applied to perform a coarse bifurcation analysis of microscopic particle models describing first car traffic on single lane highways and second pedestrian flow in two space dimensions. The results include an equation-free continuation of traveling wave solutions, identification of saddle-node and Hopf-bifurcations as well as two-parameter continuations of bifurcation points.
