@misc{1795, abstract = {{Distributed revision control is widespread throughout the software industry. Systems like git and mercurial gained a lot of users over the last years and started to supersede central systems like Subversion or CVS in some projects. While restricting access to those central systems is basically possible, it is difficult to control the propagation of contents in a distributed revision control system because every user has a local copy of the whole repository. In this thesis a concept is developed and implemented that allows secure storage of confidential data in a distributed revision control system and enables users to manage read and write permissions on single confidential files. Therefore different cryptographic methods are used, such as asymmetric encryption, digital signatures and convergent encryption. These techniques are applied in a manner that fits the special requirements of a revision control system and allows a space efficient storage of changes to the encrypted files.}}, author = {{Lass, Michael}}, publisher = {{Paderborn University}}, title = {{{Sichere Speicherung vertraulicher Daten in verteilten Versionskontrollsystemen}}}, year = {{2013}}, } @inproceedings{1798, author = {{Keller, Matthias and Robbert, Christoph and Peuster, Manuel}}, booktitle = {{Proceedings of the ACM SIGCOMM 2013 conference on SIGCOMM }}, title = {{{An evaluation testbed for adaptive, topology-aware deployment of elastic applications}}}, year = {{2013}}, } @inproceedings{1799, author = {{Ali-Ahmad, Hassan and Cicconetti, Claudio and de la Oliva, Antonio and Draxler, Martin and Gupta, Rohit and Mancuso, Vincenzo and Roullet, Laurent and Sciancalepore, Vincenzo}}, booktitle = {{2013 Second European Workshop on Software Defined Networks}}, isbn = {{9781479924332}}, publisher = {{IEEE}}, title = {{{CROWD: An SDN Approach for DenseNets}}}, doi = {{10.1109/ewsdn.2013.11}}, year = {{2013}}, } @inbook{1800, author = {{Blanckenstein, Johannes and Garcia-Jimenez, Javier and Klaue, Jirka and Karl, Holger}}, booktitle = {{Lecture Notes in Electrical Engineering}}, isbn = {{9783319030708}}, issn = {{1876-1100}}, pages = {{165--177}}, publisher = {{Springer International Publishing}}, title = {{{A Scalable Redundant TDMA Protocol for High-Density WSNs Inside an Aircraft}}}, doi = {{10.1007/978-3-319-03071-5_18}}, year = {{2013}}, } @misc{18000, author = {{Blumentritt, Fritz}}, publisher = {{Universität Paderborn}}, title = {{{Cliquenbildung in verteilten Systemen}}}, year = {{2013}}, } @inproceedings{1802, author = {{Wette, P. and Graffi, K.}}, booktitle = {{2013 Conference on Networked Systems}}, isbn = {{9781467356459}}, publisher = {{IEEE}}, title = {{{Adding Capacity-Aware Storage Indirection to Homogeneous Distributed Hash Tables}}}, doi = {{10.1109/netsys.2013.9}}, year = {{2013}}, } @inproceedings{1803, author = {{Dannewitz, Christian and Herlich, Matthias and Karl, Holger}}, booktitle = {{37th Annual IEEE Conference on Local Computer Networks -- Workshops}}, isbn = {{9781467321297}}, publisher = {{IEEE}}, title = {{{OpenNetInf - prototyping an information-centric Network Architecture}}}, doi = {{10.1109/lcnw.2012.6424044}}, year = {{2013}}, } @inbook{1804, author = {{de la Oliva, Antonio and Morelli, Arianna and Mancuso, Vincenzo and Draexler, Martin and Hentschel, Tim and Melia, Telemaco and Seite, Pierrick and Cicconetti, Claudio}}, booktitle = {{Lecture Notes of the Institute for Computer Sciences, Social Informatics and Telecommunications Engineering}}, isbn = {{9783642379345}}, issn = {{1867-8211}}, pages = {{28--41}}, publisher = {{Springer Berlin Heidelberg}}, title = {{{Denser Networks for the Future Internet, the CROWD Approach}}}, doi = {{10.1007/978-3-642-37935-2_3}}, year = {{2013}}, } @book{18064, editor = {{Meister, Dorothee M. and von Gross, F. and Sander, U.}}, publisher = {{Juventa Verlag}}, title = {{{Enzyklopädie Erziehungswissenschaft Online - Medienpädagogik}}}, year = {{2013}}, } @inbook{18081, author = {{Kamin, A.-M. and Meister, Dorothee M.}}, booktitle = {{Enzyklopädie Erziehungswissenschaft }}, editor = {{Meister, Dorothee M. and von Gross, F. and Sander, U.}}, publisher = {{Beltz Juventa}}, title = {{{Medienpädagogik in Institutionen der Erwachsenen- und Weiterbildung}}}, year = {{2013}}, } @inbook{18082, author = {{Meister, Dorothee M.}}, booktitle = {{Medienkompetenzförderung für Kinder und Jugendliche.

The amount of used powder, which is not sintered, can be refreshed and used for further building jobs. Due to cost reduction, better mechanical properties and a simpler processing it is reasonable to combine virgin and used powder for part manufacturing. During the building time the powder is thermally loaded and its structure is changed. State of the art in laser sintering is a defined powder ratio. Since the powder ageing depends on the individual history of sintering, this procedure cannot ensure a defined powder quality. However, for a serial production it is necessary to characterize the raw material, as well as all other steps along the process chain, in order to ensure a high reproducibility and reliability. Rheological, physical and particle properties are considered to correlate powder and chosen material properties. Different powder qualities adjusted by the Melt Volume Rate (MVR) are tested using promising rheological properties like viscosity or molecular weight. Investigations about powder bed density, bulk properties as well as thermal characterization complement the experimental setup. These parameters are correlated with mechanical, electrical, thermal and physical material properties of laser sintered parts. The most important influencing factors along the process chain are kept constant. At the end a procedure is shown to obtain a defined powder quality. This procedure will be transferred to other materials and will be tested using other laser sintering machines of the same type as well as other types.}}, author = {{Rüsenberg, Stefan and Schmid, Hans-Joachim}}, booktitle = {{International Conference of the Polymer-Processing-Society (PPS)}}, title = {{{Advanced characterization method of Nylon 12 materials for application in laser sinter processing}}}, doi = {{10.1063/1.4873877}}, volume = {{29}}, year = {{2013}}, } @inproceedings{22197, author = {{Josupeit, Stefan and Rüsenberg, Stefan and Schmid, Hans-Joachim}}, booktitle = {{Merseburger Rapid Prototyping Forum}}, title = {{{Mechanische und rheologische Untersuchungen neuer Laser Sinter Materialien}}}, doi = {{https://www.rp-netzwerk.de/images/stories/pdf/rapid_7/Universitaet_Paderborn_DMRC_RP-Forum2013.pdf}}, volume = {{7}}, year = {{2013}}, } @inproceedings{22201, author = {{Rüsenberg, Stefan and Bagsik, A. and Büsching, J. and Schmid, Hans-Joachim}}, booktitle = {{RapidTech}}, title = {{{Additiv versus Konventionell: Benchmarking am Beispiel eines Designs aus der Luftfahrtindustrie}}}, year = {{2013}}, } @inproceedings{22373, author = {{Adam, Guido and Zimmer, Detmar}}, title = {{{Design for additive manufacturing}}}, year = {{2013}}, } @article{22374, abstract = {{Additive Fertigungsverfahren stellen Bauteile und Baugruppen aus Kunststoff- oder Metallwerkstoffen schicht¬weise, ohne formgebendes Werkzeug her.
