The algorithms are checked for their suitability for the present optimization problem and optimal simulation conditions are determined, with the focus on minimal processing time. The procedure leads to a very good agreement between experimental and simulated spectra in a passable period of time.

While motion cost and communications cost constitute the primary energy consumers, each of them is investigated independently. By taking into account the power consumption of both entities, the overall energy efficiency of a system can be further improved. In this paper, the energy optimization problem of radio communication and motion is examined. We consider a hybrid wireless network that consists of a single autonomous mobile node and multiple relay nodes. The mobile node interacts with the relays within its vicinity by continuously communicating high-bandwidth data, e.g. triggered by a multimedia application like video surveillance. The goal is to find the best path such that the energy consumption for both mobility and communications is minimized. We introduce the Radio-Energy-Aware (REA) path computation strategy by utilizing node mobility. Given the starting point, the target point and the position of the relays, our simulation results show that the proposed strategy improves the energy efficiency of mobile node compared to the Motion-Energy-Aware (MEA) path constructed based only on the mobility cost. }}, author = {{Ooi, Chia Ching and Schindelhauer, Christian}}, booktitle = {{MWCN'08: Proc. of IFIP Joint Conference on Mobile Wireless Communications Networks (MWCN 2008) and Personal Wireless Communications (PWC 2008)}}, isbn = {{9780387848389}}, issn = {{1571-5736}}, publisher = {{Springer}}, title = {{{Detours Save Energy in Mobile Wireless Networks}}}, doi = {{10.1007/978-0-387-84839-6_6}}, year = {{2008}}, } @book{25839, author = {{Parisi, Salvatore}}, publisher = {{Verlagsschriftenreihe des Heinz Nixdorf Instituts, Paderborn}}, title = {{{A Method for the intelligent Authoring of 3D Animations for Traimimg and Maintenance}}}, volume = {{228}}, year = {{2008}}, } @article{25938, author = {{Karaolis-Danckert, N and Buyken, Anette and Kulig, M and Kroke, A and Forster, J and Kamin, W and Schuster, A and Hornberg, C and Keil, T and Bergmann, RL and Wahn, U and Lau, S}}, issn = {{0002-9165}}, journal = {{Am J Clin Nutr}}, number = {{5}}, pages = {{1356--1364}}, title = {{{How pre- and postnatal risk factors modify the effect of rapid weight gain in infancy and early childhood on subsequent fat mass development: results from the Multicenter Allergy Study 90.}}}, doi = {{10.1093/ajcn/87.5.1356}}, volume = {{87}}, year = {{2008}}, } @article{26891, author = {{Buyken, Anette and Karaolis-Danckert, Nadina and Remer, Thomas}}, issn = {{0002-9165}}, journal = {{The American Journal of Clinical Nutrition}}, pages = {{221--230}}, title = {{{Association of prepubertal body composition in healthy girls and boys with the timing of early and late pubertal markers}}}, doi = {{10.3945/ajcn.2008.26733}}, year = {{2008}}, } @article{26892, author = {{Libuda, Lars and Alexy, Ute and Buyken, Anette and Sichert-Hellert, Wolfgang and Stehle, Peter and Kersting, Mathilde}}, issn = {{0007-1145}}, journal = {{British Journal of Nutrition}}, title = {{{Consumption of sugar-sweetened beverages and its association with nutrient intakes and diet quality in German children and adolescents}}}, doi = {{10.1017/s0007114508094671}}, year = {{2008}}, } @article{27137, author = {{Libuda, Lars and Alexy, Ute and Remer, Thomas and Stehle, Peter and Schoenau, Eckhard and Kersting, Mathilde}}, issn = {{0002-9165}}, journal = {{The American Journal of Clinical Nutrition}}, pages = {{1670--1677}}, title = {{{Association between long-term consumption of soft drinks and variables of bone modeling and remodeling in a sample of healthy German children and adolescents}}}, doi = {{10.3945/ajcn.2008.26414}}, year = {{2008}}, } @article{27586, author = {{Libuda, Lars and Alexey, U. and Stehle, P. and Kersting, M.}}, journal = {{Aktuelle Ernährungsmedizin}}, pages = {{123--131}}, title = {{{Konsum von Erfrischungsgetränken und Entwicklung des Körpergewichts im Kindes- und Jugendalter – Gibt es eine Verbindung? }}}, doi = {{10.1055/s-2007-986311}}, volume = {{33}}, year = {{2008}}, } @article{27587, author = {{Libuda, Lars and Kersting, M.}}, journal = {{Ernährungsumschau}}, pages = {{646}}, title = {{{DONALD News: Erfrischungsgetränke und Ernährungsqualität. }}}, volume = {{55}}, year = {{2008}}, } @article{27714, author = {{Buyken, Anette and Karaolis-Danckert, Nadina and Remer, Thomas and Bolzenius, Katja and Landsberg, Beate and Kroke, Anja}}, issn = {{1930-7381}}, journal = {{Obesity}}, pages = {{389--395}}, title = {{{Effects of Breastfeeding on Trajectories of Body Fat and BMI throughout Childhood}}}, doi = {{10.1038/oby.2007.57}}, year = {{2008}}, } @article{27773, author = {{Toeller, M. and Buyken, Anette and Heitkamp, G. and Berg, G. and Scherbaum, W.}}, issn = {{0018-5043}}, journal = {{Hormone and Metabolic Research}}, pages = {{680--685}}, title = {{{Prevalence of Chronic Complications, Metabolic Control and Nutritional Intake in Type 1 Diabetes: Comparison Between Different European Regions}}}, doi = {{10.1055/s-2007-978820}}, year = {{2008}}, } @inbook{27887, author = {{Schlegel-Matthies, Kirsten}}, booktitle = {{Ernährung, Kultur, Lebensqualität.

It is difficult to determine the individual robot’s behavior based on the swarm behavior and vice versa due to the high number of agent–agent interactions. A step towards a solution of this problem is the development of appropriate models which accurately predict the swarm behavior based on a specified control algorithm. Such models would reduce the necessary number of time-consuming simulations and experiments during the design process of an algorithm. In this paper we propose a model with focus on an explicit representation of space because the effectiveness of many swarm robotic scenarios depends on spatial inhomogeneity. We use methods of statistical physics to address spatiality. Starting from a description of a single robot we derive an abstract model of swarm motion. The model is then extended to a generic model framework of communicating robots. In two examples we validate models against simulation results. Our experience shows that qualitative correctness is easily achieved, while quantitative correctness is disproportionately more difficult but still possible.}}, author = {{Hamann, Heiko and Wörn, Heinz}}, issn = {{1935-3812}}, journal = {{Swarm Intelligence}}, number = {{2-4}}, pages = {{209--239}}, title = {{{A framework of space–time continuous models for algorithm design in swarm robotics}}}, doi = {{10.1007/s11721-008-0015-3}}, volume = {{2}}, year = {{2008}}, }
