Integrating applications running on different devices is often a problem, because the services provided by those applications are not meant to be integrated. In this demonstration, we present our XDAI-A framework which enables cross-device integration of services provided by Android apps. The framework uses adapters to convert Android-internal service interfaces of existing apps into external services with a platform-independent interface that can be accessed from applications on other devices and even other platforms. Our ready-to-use framework does not require to alter existing Android apps, since the adapters are installed separately. For the convenient specification of adapters, our framework comes with a domain-specific language (DSL). Additionally, we provide an infrastructure to find and integrate devices and their applications' services.}}, author = {{Wolters, Dennis and Kirchhoff, Jonas and Gerth, Christian and Engels, Gregor}}, booktitle = {{Service-Oriented Computing -- ICSOC 2016 Workshops}}, editor = {{Drira, Khalil and Wang, Hongbing and Yu, Qi and Wang, Yan and Yan, Yuhong and Charoy, François and Mendling, Jan and Mohamed, Mohamed and Wang, Zhongjie and Bhiri, Sami}}, isbn = {{978-3-319-68136-8}}, pages = {{203--206}}, publisher = {{Springer International Publishing}}, title = {{{XDAI-A: Framework for Enabling Cross-Device Integration of Android Apps}}}, doi = {{10.1007/978-3-319-68136-8_25}}, year = {{2017}}, } @inbook{5896, author = {{Kempen, Leander and Wassong, Thomas}}, booktitle = {{Hochschuldidaktik im Dialog.

In addition to assigning jobs to processors, the scheduler must distribute the resource among the processors (e.g., for three processors in shares of 20\%, 15\%, and 65\%) and adjust this distribution over time. Each job $j$ comes with a size $p_j \in \mathbb{R}$ and a resource requirement $r_j > 0$. Jobs do not benefit when receiving a share larger than $r_j$ of the resource. But providing them with a fraction of the resource requirement causes a linear decrease in the processing efficiency. We seek a (non-preemptive) job and resource assignment minimizing the makespan.Our main result is an efficient approximation algorithm which achieves an approximation ratio of $2 + 1/(m-2)$. It can be improved to an (asymptotic) ratio of $1 + 1/(m-1)$ if all jobs have unit size. Our algorithms also imply new results for a well-known bin packing problem with splittable items and a restricted number of allowed item parts per bin.Based upon the above solution, we also derive an approximation algorithm with similar guarantees for a setting in which we introduce so-called tasks each containing several jobs and where we are interested in the average completion time of tasks (a task is completed when all its jobs are completed).}}, author = {{Kling, Peter and Mäcker, Alexander and Riechers, Sören and Skopalik, Alexander}}, booktitle = {{Proceedings of the 29th ACM Symposium on Parallelism in Algorithms and Architectures (SPAA)}}, pages = {{123----132}}, title = {{{Sharing is Caring: Multiprocessor Scheduling with a Sharable Resource}}}, doi = {{10.1145/3087556.3087578}}, year = {{2017}}, } @inproceedings{5914, abstract = {{During the last years, alternative drive technologies, for example electrically powered vehicles (EV), have gained more and more attention, mainly caused by an increasing awareness of the impact of CO2 emissions on climate change and by the limitation of fossil fuels. However, these technologies currently come with new challenges due to limited lithium ion battery storage density and high battery costs which lead to a considerably reduced range in comparison to conventional internal combustion engine powered vehicles. For this reason, it is desirable to increase the vehicle range without enlarging the battery. When the route and the road slope are known in advance, it is possible to vary the vehicles velocity within certain limits in order to reduce the overall drivetrain energy consumption. This may either result in an increased range or, alternatively, in larger energy reserves for comfort functions such as air conditioning. In this presentation, we formulate the challenge of range extension as a multiobjective optimal control problem. We then apply different numerical methods to calculate the so-called Pareto set of optimal compromises for the drivetrain power profile with respect to the two concurrent objectives battery state of charge and mean velocity. In order to numerically solve the optimal control problem by means of a direct method, a time discretization of the drivetrain power profile is necessary. In combination with a vehicle dynamics simulation model, the optimal control problem is transformed into a high dimensional nonlinear optimization problem. For the approximation of the Pareto set, two different optimization algorithms implemented in the software package GAIO are used. The first one yields a global optimal solution by applying a set-oriented subdivision technique to parameter space. By construction, this technique is limited to coarse discretizations of the drivetrain power profile. In contrast, the second technique, which is based on an image space continuation method, is more suitable when the number of parameters is large while the number of objectives is less than five. We compare the solutions of the two algorithms and study the influence of different discretizations on the quality of the solutions. A MATLAB/Simulink model is used to describe the dynamics of an EV. It is based on a drivetrain efficiency map and considers vehicle properties such as rolling friction and air drag, as well as environmental conditions like slope and ambient temperature. The vehicle model takes into account the traction battery too, enabling an exact prediction of the batterys response to power requests of drivetrain and auxiliary loads, including state of charge.}}, author = {{Dellnitz, Michael and Eckstein, Julian and Flaßkamp, Kathrin and Friedel, Patrick and Horenkamp, Christian and Köhler, Ulrich and Ober-Blöbaum, Sina and Peitz, Sebastian and Tiemeyer, Sebastian}}, booktitle = {{Progress in Industrial Mathematics at ECMI 2014 }}, isbn = {{9783319234120}}, issn = {{1612-3956}}, pages = {{633--641}}, publisher = {{Springer International Publishing}}, title = {{{Multiobjective Optimal Control Methods for the Development of an Intelligent Cruise Control}}}, doi = {{10.1007/978-3-319-23413-7_87}}, year = {{2017}}, } @misc{5946, author = {{Kühn, Sarah}}, publisher = {{Universität Paderborn}}, title = {{{Outsourcing und Qualität im Supply Chain - Eine Gleichgewichtsanalyse}}}, year = {{2017}}, } @misc{5950, author = {{Gunning, Justine}}, publisher = {{Universität Paderborn}}, title = {{{Crowdfunding Plattformen als Vermittler auf zweiseitigen Märkten - Eine mikroökonomische Analyse}}}, year = {{2017}}, } @article{5975, author = {{Tramm, T. and Kremer, H.-Hugo and Reinmann, G.}}, journal = {{bwp@ Berufs- und Wirtschaftspädagogik - online}}, number = {{30}}, title = {{{Entwicklungsbezogene Praxisforschung }}}, year = {{2017}}, } @book{5978, author = {{Kückmann, Marie-Ann and Kremer, H.-Hugo}}, title = {{{Innovationsarena 3i: Handreichung zur multiprofessionellen Teamarbeit (mpT) in der Ausbildungsvorbereitung am Berufskolleg}}}, year = {{2017}}, } @proceedings{5980, editor = {{Scheideler, Christian and Taghi Hajiaghayi, Mohammad}}, isbn = {{978-1-4503-4593-4}}, publisher = {{ACM}}, title = {{{Proceedings of the 29th ACM Symposium on Parallelism in Algorithms and Architectures, SPAA 2017, Washington DC, USA, July 24-26, 2017}}}, doi = {{10.1145/3087556}}, year = {{2017}}, } @misc{60, author = {{Niehus, David}}, publisher = {{Universität Paderborn}}, title = {{{Semantically Secure Attribute-based Searchable Encryption}}}, year = {{2017}}, } @article{6051, author = {{Menke, Peter and Ell, Basil and Cimiano, Philipp}}, issn = {{1875-8533}}, journal = {{Applied Ontology}}, number = {{2}}, pages = {{131--155}}, publisher = {{IOS Press}}, title = {{{On the origin of annotations: A module-based approach to representing annotations in the Natural Language Processing Interchange Format (NIF)}}}, doi = {{10.3233/ao-170180}}, volume = {{12}}, year = {{2017}}, } @phdthesis{61, author = {{Strothmann, Thim Frederik}}, publisher = {{Universität Paderborn}}, title = {{{Self-* Algorithms for Distributed Systems}}}, doi = {{10.17619/UNIPB/1-150}}, year = {{2017}}, } @misc{62, author = {{Weis, Eduard}}, publisher = {{Universität Paderborn}}, title = {{{Searchable Encryption}}}, year = {{2017}}, } @inbook{6240, author = {{Kremer, H.-Hugo and Beutner, Marc}}, booktitle = {{Jugendstrafvollzug - (k)ein Ort der Bildung!?}}, editor = {{Schweder, M.}}, isbn = {{9783779934523}}, pages = {{114--129}}, title = {{{"Der Unterschied ist, die hat man erwischt" - Berufliche Bildung im Jugendstrafvollzug}}}, year = {{2017}}, }
