Furthermore products and the corresponding manufacturing processes get more and more complex. Therefore, companies need new methods for the planning of manufacturing systems. One promising approach in this context is digital factory/virtual production—the modeling and analysis of computer models of the planned factory with the objective to reduce time and costs. For the modeling and analysis various simulation methods and programs have been developed. They are a highly valuable support for planning and visualizing the manufacturing system. But there is one major disadvantage: only experienced and long trained experts are able to operate with these programs. The graphical user interface is very complex and not intuitive to use. This results in an extensive and error-prone modeling of complex simulation models and a time-consuming interpretation of the simulation results.\r\n\r\nTo overcome these weak points, intuitive and understandable man–machine interfaces like augmented and virtual reality can be used. This paper describes the architecture of a system which uses the technologies of augmented and virtual reality to support the planning process of complex manufacturing systems. The proposed system assists the user in modeling, the validation of the simulation model, and the subsequent optimization of the production system. A general application of the VR- and AR-technologies and of the simulation is realized by the development of appropriate linking and integration mechanisms. For the visualization of the arising 3D-data within the VR- and AR-environments, a dedicated 3D-rendering library is used."}]},{"publication_status":"published","date_updated":"2022-01-06T06:53:11Z","author":[{"id":"146","first_name":"Matthias","last_name":"Fischer","full_name":"Fischer, Matthias"},{"first_name":"B.","last_name":"Mueck","full_name":"Mueck, B."},{"full_name":"Mahajan, K.","last_name":"Mahajan","first_name":"K."},{"full_name":"Kortenjan, M.","last_name":"Kortenjan","first_name":"M."},{"full_name":"Laroque, C.","last_name":"Laroque","first_name":"C."},{"full_name":"Dangelmaier, W.","last_name":"Dangelmaier","first_name":"W."}],"publication_identifier":{"isbn":["0780395190"]},"title":"Multi-User Support and Motion Planning of Humans and Humans Driven Vehicles in Interactive 3D Material Flow Simulations","year":"2005","status":"public","user_id":"15415","doi":"10.1109/wsc.2005.1574470","language":[{"iso":"eng"}],"_id":"17415","citation":{"ieee":"M.

In this paper we present a novel framework for analyzing property testing algorithms. Our framework is based on a connection of property testing and a new class of problems which we call abstract combinatorial programs . We show that if the problem of testing a property can be reduced to an abstract combinatorial program of small dimension , then the property has an efficient tester.\r\n\r\nWe apply our framework to a variety of problems. We present efficient property testing algorithms for geometric clustering problems, for the reversal distance problem, and for graph and hypergraph coloring problems. We also prove that, informally, any hereditary graph property can be efficiently tested if and only if it can be reduced to an abstract combinatorial program of small size.\r\n\r\nOur framework allows us to analyze all our testers in a unified way, and the obtained complexity bounds either match or improve the previously known bounds. Furthermore, even if the asymptotic complexity of the testers is not improved, the obtained proofs are significantly simpler than the previous ones. We believe that our framework will help to understand the structure of efficiently testable properties."}],"date_created":"2020-09-01T11:35:41Z","type":"journal_article","department":[{"_id":"63"}]},{"page":"866-877","language":[{"iso":"eng"}],"_id":"18768","user_id":"15415","doi":"10.1007/11523468_70","year":"2005","title":"Facility Location in Sublinear Time","status":"public","author":[{"full_name":"Bădoiu, Mihai","last_name":"Bădoiu","first_name":"Mihai"},{"last_name":"Czumaj","first_name":"Artur","full_name":"Czumaj, Artur"},{"last_name":"Indyk","first_name":"Piotr","full_name":"Indyk, Piotr"},{"last_name":"Sohler","first_name":"Christian","full_name":"Sohler, Christian"}],"publication_identifier":{"isbn":["9783540275800","9783540316916"],"issn":["0302-9743","1611-3349"]},"publication_status":"published","date_updated":"2022-01-06T06:53:52Z","date_created":"2020-09-01T11:53:19Z","place":"Berlin, Heidelberg","type":"conference","department":[{"_id":"63"}],"publication":"Proc. of the 32nd International Colloquium on Automata, Languages and Programming (ICALP)","citation":{"short":"M.

We develop streaming (1 + ɛ)-approximation algorithms for k-median, k-means, MaxCut, maximum weighted matching (MaxWM), maximum travelling salesperson (MaxTSP), maximum spanning tree (MaxST), and average distance over dynamic geometric data streams. Our algorithms maintain a small weighted set of points (a coreset) that approximates with probability 2/3 the current point set with respect to the considered problem during the m insert/delete operations of the data stream. They use poly(ɛ −1, log m, log ∆) space and update time per insert/delete operation for constant k and dimension d. Having a coreset one only needs a fast approximation algorithm for the weighted problem to compute a solution quickly. In fact, even an exponential algorithm is sometimes feasible as its running time may still be polynomial in n. For example one can compute in poly(log n, exp(O((1+log(1/ɛ)/ɛ) d−1))) time a solution to k-median and k-means [21] where n is the size of the current point set and k and d are constants. Finding an implicit solution to MaxCut can be done in poly(log n, exp((1/ɛ) O(1))) time. For MaxST and average distance we require poly(log n, ɛ −1) time and for MaxWM we require O(n 3) time to do this."}],"date_created":"2020-09-01T13:49:23Z","type":"conference","department":[{"_id":"63"}],"status":"public","year":"2005","title":"Coresets in Dynamic Geometric Data Streams","author":[{"first_name":"Christian","last_name":"Sohler","full_name":"Sohler, Christian"},{"last_name":"Frahling","first_name":"Gereon","full_name":"Frahling, Gereon"}],"date_updated":"2022-01-06T06:53:52Z","page":"209-217","_id":"18787","language":[{"iso":"eng"}],"user_id":"15415"},{"status":"public","_id":"18790","page":"37-52","volume":331,"user_id":"15415","citation":{"ieee":"A.
