Predicting a system of many components with a huge amount of interactions is beyond human skills. The currently common use of simulations for design support is not satisfying, as it is time-consuming and the results are most likely sub- optimal. In this work, we present the derivation of an analytical, time-, and space-continuous model for a swarm of autonomous robots based on the Fokker-Planck equation. While the motion model is in most parts physically motivated, the communication model is based on a heuristic approach. A showcase application to a recently proposed scenario of collective perception in a huge swarm of robots with very limited abilities is given and the simulation results are compared to the model. Despite the high level of abstraction, the prediction discrepancies are small and the parameters can be mapped one-to-one from the model to the control algorithm. Finally, we give an outlook on the capabilities of the proposed model, discuss its limitations, and suggest an improvement that could reduce the number of empirically determined parameters."}],"_id":"20432","language":[{"iso":"eng"}],"page":"23--31","user_id":"15415","doi":"10.1109/saso.2007.3","author":[{"last_name":"Hamann","first_name":"Heiko","full_name":"Hamann, Heiko"},{"full_name":"Wörn, Heinz","first_name":"Heinz","last_name":"Wörn"}],"publication_identifier":{"isbn":["0769529062"]},"status":"public","title":"A Space- and Time-Continuous Model of Self-Organizing Robot Swarms for Design Support","year":"2007","publication_status":"published","date_updated":"2022-01-06T06:54:27Z"},{"intvolume":"        17","date_updated":"2022-01-06T06:54:27Z","author":[{"first_name":"Heiko","last_name":"Hamann","full_name":"Hamann, Heiko"},{"full_name":"Wörn, Heinz","last_name":"Wörn","first_name":"Heinz"},{"full_name":"Nagy, Marius","last_name":"Nagy","first_name":"Marius"},{"first_name":"Naya","last_name":"Nagy","full_name":"Nagy, Naya"}],"status":"public","year":"2007","title":"Embodied Computation","volume":17,"user_id":"15415","_id":"20433","language":[{"iso":"eng"}],"page":"287--298","citation":{"ama":"Hamann H, Wörn H, Nagy M, Nagy N.

First, the design and the control of 5 to 10cm3 sized mobile micro robots with five degrees of freedom will be shown. They can handle miniaturized parts as for example an optical component or a biological cell with a size in the micrometre-area with an accuracy of 100nm under a microscope or a raster-electron microscope. Second, the design and the control of a 1cm3-sized mobile untethered micro robot will be demonstrated. Here, the robot consists of five parts: the Piezzo locomotion module, the micro control unit, the communication unit, the navigation system and the micro gripper. The mobile robot can be guided and positioned in an arena with an accuracy of 5 micrometre and can be programmed and controlled over the wireless communication unit. Third, the design and the control of 3 × 3 × 3 mm3 sized micro-/nanorobots with 2 degrees of freedom will be presented. The transmission of energy and the communication between the robots is realized via infrared. The robot controller is fully integrated and has limited functionalities. Via basic sensors communication functions and elementary rules and behaviours the micro robot can act in a swarm consisting of hundreds and thousands of robots. Future applications could be monitoring-, inspection-, exploring-tasks etc. of big areas or objects."}],"date_created":"2020-11-19T11:37:49Z","department":[{"_id":"63"},{"_id":"238"}],"type":"conference","author":[{"first_name":"Heiko","last_name":"Hamann","full_name":"Hamann, Heiko"},{"full_name":"Szymanski, Marc","last_name":"Szymanski","first_name":"Marc"},{"full_name":"Wörn, Heinz","last_name":"Wörn","first_name":"Heinz"},{"full_name":"Estana, Ramon","last_name":"Estana","first_name":"Ramon"},{"last_name":"Xie","first_name":"Ming","full_name":"Xie, Ming"},{"full_name":"Dubowsky, Steven","first_name":"Steven","last_name":"Dubowsky"}],"status":"public","title":"From Micro to Nano and Swarm Robotics","year":"2007","date_updated":"2022-01-06T06:54:27Z","_id":"20434","language":[{"iso":"eng"}],"page":"15--24","doi":"10.1142/9789812770189_0003","user_id":"15415"},{"date_created":"2020-08-14T13:30:00Z","department":[{"_id":"63"}],"type":"journal_article","citation":{"ama":"Ziegler M.

The method developed therefore clones existing simulation runs online and allows the navigation within these existing simulation runs.

The space used by our algorithm to estimate the clustering coefficient is inversely related to the clustering coefficient of the network itself. The space used by our algorithm to compute the number K 3,3 of bipartite cliques is proportional to the ratio between the number of K 1,3 and K 3,3 in the graph.\r\n\r\nSince the space complexity depends only on the structure of the input graph and not on the number of nodes, our algorithms scale very well with increasing graph size. Therefore they provide a basic tool to analyze the structure of dense clusters in large graphs and have many applications in the discovery of web communities, the analysis of the structure of large social networks and the probing of frequent patterns in large graphs.\r\n\r\nWe implemented both algorithms and evaluated their performance on networks from different application domains and of different size; The largest instance is a webgraph consisting of more than 135 million nodes and 1 billion edges.

The density can be determined in an efficient scheme by solving one-particle non-interacting Schrödinger equations—the Kohn–Sham equations. The complication of the problem is hidden in the—unknown—time-dependent exchange and correlation potential that appears in the Kohn–Sham equations and for which it is essential to find good approximations. Many approximations have been suggested and tested for finite systems, where even the very simple adiabatic local-density approximation (ALDA) has often proved to be successful. In the case of solids, ALDA fails to reproduce optical absorption spectra, which are instead well described by solving the Bethe–Salpeter equation of many-body perturbation theory (MBPT). On the other hand, ALDA can lead to excellent results for loss functions (at vanishing and finite momentum transfer). In view of this and thanks to recent successful developments of improved linear-response kernels derived from MBPT, TDDFT is today considered a promising alternative to MBPT for the calculation of electronic spectra, even for solids. After reviewing the fundamentals of TDDFT within linear response, we discuss different approaches and a variety of applications to extended systems."}],"extern":"1","language":[{"iso":"eng"}],"doi":"10.1088/0034-4885/70/3/r02","title":"Time-dependent density-functional theory for extended systems","year":"2007","author":[{"first_name":"Silvana","last_name":"Botti","full_name":"Botti, Silvana"},{"full_name":"Schindlmayr, Arno","last_name":"Schindlmayr","first_name":"Arno","orcid":"0000-0002-4855-071X","id":"458"},{"last_name":"Del Sole","first_name":"Rodolfo","full_name":"Del Sole, Rodolfo"},{"first_name":"Lucia","last_name":"Reining","full_name":"Reining, Lucia"}],"publication_identifier":{"eissn":["1361-6633"],"issn":["0034-4885"]},"date_updated":"2022-01-06T06:53:40Z","publication_status":"published","intvolume":"        70","article_type":"review","external_id":{"isi":["000244875800003"]},"file_date_updated":"2020-08-30T15:37:17Z","isi":"1","citation":{"bibtex":"@article{Botti_Schindlmayr_Del Sole_Reining_2007, title={Time-dependent density-functional theory for extended systems}, volume={70}, DOI={<a href=\"https://doi.org/10.1088/0034-4885/70/3/r02\">10.1088/0034-4885/70/3/r02</a>}, number={3}, journal={Reports on Progress in Physics}, publisher={IOP Publishing}, author={Botti, Silvana and Schindlmayr, Arno and Del Sole, Rodolfo and Reining, Lucia}, year={2007}, pages={357–407} }","ama":"Botti S, Schindlmayr A, Del Sole R, Reining L.

As a major new result, we identify the bond length between the octahedrally coordinated iron atoms and their neighbouring oxygen atoms as the main characteristic parameter, and we show that the transition occurs if external strain reduces this interatomic distance from 2.06 Å in equilibrium to below a critical value of 1.99 Å.

It combines the strength of density-functional theory for ground-state total energies with quasiparticle corrections to the excitation spectrum obtained from many-body perturbation theory. The latter is implemented within the G0W0 approximation, in which the electronic self-energy is constructed non-self-consistently from the Green’s function of the underlying Kohn–Sham system. The method is general and applicable to arbitrary bulk or surface defects. As an example we consider anion vacancies at the (110) surfaces of III–V semiconductors. Relative to the Kohn–Sham eigenvalues in the local-density approximation, the quasiparticle corrections open the fundamental band gap and raise the position of defect states inside the gap. As a consequence, the charge-transition levels are also pushed to higher energies, leading to close agreement with the available experimental data."}],"extern":"1","file":[{"creator":"schindlm","date_created":"2020-08-28T16:49:56Z","description":"© 2007 Springer-Verlag, Berlin, Heidelberg","file_size":649066,"access_level":"closed","file_name":"Schindlmayr-Scheffler2007_Chapter_QuasiparticleCalculationsForPo.pdf","date_updated":"2020-08-30T15:42:34Z","relation":"main_file","content_type":"application/pdf","file_id":"18594","title":"Quasiparticle calculations for point defects at semiconductor surfaces"}],"date_created":"2020-08-28T16:43:51Z","type":"book_chapter"}]
