An example for this are embedded systems in autonomous cars that communicate in order to coordinate their actions. Our model is a variant of the classical Page Migration Problem. Moreformally, we consider a mobile server holding a data page.The server can move in the Euclidean space (of arbitrary dimension). In every round, requests for data items from the page pop up at arbitrary points in the space. The requests are served, each at a cost of the distance from the requesting point and the server, and the mobile server may move, at a cost D times the distance traveled for some constant D . We assume a maximum distance m the server is allowed to move per round. We show that no online algorithm can achieve a competitive ratio independent of the length of the input sequence in this setting. Hence we augment the maximum movement distance of the online algorithms to ( 1 + δ) times the maximum distance of the offline solution. We provide a deterministic algorithm which is simple to describe and works for multiple variants of our problem. The algorithm achieves almost tight competitive ratios independent of the length of the input sequence.}}, author = {{Feldkord, Björn and Meyer auf der Heide, Friedhelm}}, booktitle = {{Proceedings of the 29th ACM Symposium on Parallelism in Algorithms and Architectures (SPAA)}}, pages = {{313--319}}, title = {{{The Mobile Server Problem}}}, doi = {{10.1145/3087556.3087575}}, year = {{2017}}, } @inproceedings{65, abstract = {{Heterogeneous compute nodes in form of CPUs with attached GPU and FPGA accelerators have strongly gained interested in the last years. Applications differ in their execution characteristics and can therefore benefit from such heterogeneous resources in terms of performance or energy consumption. While performance optimization has been the only goal for a long time, nowadays research is more and more focusing on techniques to minimize energy consumption due to rising electricity costs.This paper presents reMinMin, a novel static list scheduling approach for optimizing the total energy consumption for a set of tasks executed on a heterogeneous compute node. reMinMin bases on a new energy model that differentiates between static and dynamic energy components and covers effects of accelerator tasks on the host CPU. The required energy values are retrieved by measurements on the real computing system. In order to evaluate reMinMin, we compare it with two reference implementations on three task sets with different degrees of heterogeneity. In our experiments, MinMin is consistently better than a scheduler optimizing for dynamic energy only, which requires up to 19.43% more energy, and very close to optimal schedules.}}, author = {{Lösch, Achim and Platzner, Marco}}, booktitle = {{Proceedings of the 28th Annual IEEE International Conference on Application-specific Systems, Architectures and Processors (ASAP)}}, title = {{{reMinMin: A Novel Static Energy-Centric List Scheduling Approach Based on Real Measurements}}}, doi = {{10.1109/ASAP.2017.7995272}}, year = {{2017}}, } @article{6552, author = {{Bause, Fabian and Claes, Leander and Webersen, Manuel and Johannesmann, Sarah and Henning, Bernd}}, issn = {{0171-8096}}, journal = {{tm - Technisches Messen}}, number = {{3}}, title = {{{Viskoelastizität und Anisotropie von Kunststoffen: Ultraschallbasierte Methoden zur Materialparameterbestimmung}}}, doi = {{10.1515/teme-2016-0056}}, volume = {{84}}, year = {{2017}}, } @inproceedings{6556, author = {{Claes, Leander and Chatwell, René Spencer and Vrabec, Jadran and Henning, Bernd}}, booktitle = {{PROCEEDINGS -- AMA Conferences 2017}}, isbn = {{978-3-9816876-4-4}}, pages = {{304--309}}, publisher = {{AMA Service GmbH}}, title = {{{A Spectral Approach to Acoustic Absorption Measurement}}}, doi = {{10.5162/sensor2017/C1.2}}, year = {{2017}}, } @inproceedings{6557, author = {{Claes, Leander and Jäger, Axel and Johannesmann, Sarah and Webersen, Manuel and Kupnik, Mario and Henning, Bernd}}, booktitle = {{PROCEEDINGS -- AMA Conferences 2017}}, isbn = {{978-3-9816876-4-4}}, pages = {{605--610}}, publisher = {{AMA Service GmbH}}, title = {{{Acoustic Material Characterization of Additively Manufactured Components}}}, doi = {{10.5162/sensor2017/P2.9}}, year = {{2017}}, } @inproceedings{6559, author = {{Claes, Leander and Zeipert, Henning and Koppa, Peter and Tröster, Thomas and Henning, Bernd}}, booktitle = {{Proceedings of Meetings on Acoustics}}, pages = {{030004}}, title = {{{Additively manufactured acoustic diffuser structures for ultrasonic measurement applications}}}, doi = {{10.1121/2.0000688}}, year = {{2017}}, } @inproceedings{6565, author = {{Jäger, Axel and Johannesmann, Sarah and Claes, Leander and Webersen, Manuel and Henning, Bernd and Kupnik, Mario}}, booktitle = {{2017 IEEE IUS~Proceedings}}, title = {{{Evaluating the Influence of 3D-Printing Parameters on Acoustic Material Properties}}}, year = {{2017}}, } @inproceedings{6566, author = {{Johannesmann, Sarah and Claes, Leander and Webersen, Manuel and Henning, Bernd}}, booktitle = {{Fortschritte der Akustik - DAGA 2017}}, pages = {{999--1002}}, publisher = {{Deutsche Gesellschaft für Akustik e.V. 2017}}, title = {{{Inverser Ansatz zur akustischen Charakterisierung plattenförmiger Materialproben}}}, year = {{2017}}, } @inproceedings{6572, author = {{Jurgelucks, Benjamin and Feldmann, Nadine and Claes, Leander and Henning, Bernd and Walther, Andrea}}, booktitle = {{Proceedings of Meetings on Acoustics}}, pages = {{030010}}, title = {{{Material parameter determination of a piezoelectric disc with triple-ring-electrodes for increased sensitivity}}}, doi = {{10.1121/2.0000707}}, year = {{2017}}, } @inproceedings{6575, author = {{Bause, Fabian and Claes, Leander and Webersen, Manuel and Henning, Bernd}}, booktitle = {{PROCEEDINGS -- AMA Conferences 2017}}, isbn = {{978-3-9816876-4-4}}, pages = {{414}}, title = {{{Ultrasonic measurements in the characterization of viscoelasticity and aging of polymers}}}, doi = {{10.5162/sensor2017/C8.1}}, year = {{2017}}, } @inproceedings{6583, author = {{Feldmann, Nadine and Bause, Fabian and Henning, Bernd}}, booktitle = {{Proceedings – AMA Conferences 2017}}, title = {{{Determining fractional Zener model parameters from low frequency DMA measurements}}}, doi = {{10.5162/SENSOR2017/B1.4}}, year = {{2017}}, } @misc{6591, author = {{Claes, Leander and Feldmann, Nadine and Henning, Bernd}}, title = {{{Spektrale Verfahren zur Bestimmung der akustischen Absorption in fluiden Medien}}}, year = {{2017}}, } @inproceedings{66, abstract = {{In budget games, players compete over resources with finite budgets.

If the total demand on a resource does not exceed its budget, the utility of each player who chose that resource equals his demand. Otherwise, the budget is shared proportionally. In the general case, pure Nash equilibria (NE) do not exist for such games. In this paper, we consider the natural classes of singleton and matroid budget games with additional constraints and show that for each, pure NE can be guaranteed.

An example using PCM as cooling storage for refrigerators that has been investigated: A focus of this paper is the use of that load shifting ability to provide balancing power. Another emphasis is on the protection of individual consumer data: To keep the state of use of each individual consumer (actually: interactive consumer or “prosumer”) anonymous, but still performing the sales of balancing power, the orders for load-dispatching can be transmitted via transmitted via a regional, non-individual broadcasting message within the GSM network. Demonstrating DSMs capacities, abilities and limits concerning domestic applications is an important task to prepare large-scale implementation and to convince stakeholders.
