@inproceedings{499, abstract = {{We present a new online algorithm for profit-oriented scheduling on multiple speed-scalable processors.Moreover, we provide a tight analysis of the algorithm's competitiveness.Our results generalize and improve upon work by \citet{Chan:2010}, which considers a single speed-scalable processor.Using significantly different techniques, we can not only extend their model to multiprocessors but also prove an enhanced and tight competitive ratio for our algorithm.In our scheduling problem, jobs arrive over time and are preemptable.They have different workloads, values, and deadlines.The scheduler may decide not to finish a job but instead to suffer a loss equaling the job's value.However, to process a job's workload until its deadline the scheduler must invest a certain amount of energy.The cost of a schedule is the sum of lost values and invested energy.In order to finish a job the scheduler has to determine which processors to use and set their speeds accordingly.A processor's energy consumption is power $\Power{s}$ integrated over time, where $\Power{s}=s^{\alpha}$ is the power consumption when running at speed $s$.Since we consider the online variant of the problem, the scheduler has no knowledge about future jobs.This problem was introduced by~\citet{Chan:2010} for the case of a single processor.They presented an online algorithm which is $\alpha^{\alpha}+2e\alpha$-competitive.We provide an online algorithm for the case of multiple processors with an improved competitive ratio of $\alpha^{\alpha}$.}}, author = {{Kling, Peter and Pietrzyk, Peter}}, booktitle = {{Proceedings of the 25th ACM Symposium on Parallelism in Algorithms and Architectures (SPAA)}}, pages = {{251--260 }}, title = {{{Profitable Scheduling on Multiple Speed-Scalable Processors}}}, doi = {{10.1145/2486159.2486183}}, year = {{2013}}, } @inproceedings{4991, author = {{Oertel, Simon and Thommes, Kirsten and Walgenbach, Peter}}, booktitle = {{Academy of Management Proceedings}}, number = {{1}}, pages = {{11642}}, title = {{{Born in the GDR: Imprinting, Structural Inertia and the Survival Chances of Organizations}}}, year = {{2013}}, } @inproceedings{4992, author = {{Thommes, Kirsten and Akkerman, Agnes and Vyrastekova, Jana}}, booktitle = {{Academy of Management Proceedings}}, number = {{1}}, pages = {{12251}}, title = {{{The after effects of strikes on team collaboration-experimental evidence}}}, year = {{2013}}, } @book{6984, editor = {{Beutner, Marc and Kremer, H.-Hugo and Wirth, W.}}, title = {{{Berufsorientierung, Gewaltsensibilisierung und Kompetenzentwicklung - Konzepte zur beruflichen Bildung im JUngtätervollzug}}}, year = {{2013}}, } @article{6985, author = {{Kremer, H.-Hugo and Fischer, M. and Tramm, T.}}, journal = {{bwp@ Berufs- und Wirtschaftspädagogik - online}}, number = {{24}}, title = {{{Didaktik beruflicher Bildung}}}, year = {{2013}}, } @book{6986, editor = {{Feng, X. and Rützel, J. and Kremer, H.-Hugo}}, title = {{{Standardization, professionalization and the measurements}}}, year = {{2013}}, } @article{7236, author = {{Lo, Fang-Yuh and Guo, Jhong-Yu and Huang, Cheng-De and Chou, Kai-Chieh and Liu, Hsiang-Lin and Ney, Verena and Ney, Andreas and Chern, Ming-Yau and Shvarkov, Stepan and Reuter, Dirk and Wieck, Andreas D. and Pezzagna, Sébastien and Massies, Jean}}, issn = {{1567-1739}}, journal = {{Current Applied Physics}}, pages = {{S7--S11}}, publisher = {{Elsevier BV}}, title = {{{Evidences of defect contribution in magnetically ordered Sm-implanted GaN}}}, doi = {{10.1016/j.cap.2013.11.051}}, volume = {{14}}, year = {{2013}}, } @article{7239, author = {{Steinhoff, A. and Kurtze, H. and Gartner, P. and Florian, M. and Reuter, Dirk and Wieck, A.
