Thus, biomechanical analysis of textile devices has to include the impact of strain on stretchability and effective porosity. Prolift® and Prolift + M®, developed for tension free conditions, were tested by measuring stretchability and effective porosity applying mechanical strain. For comparison, we used Dynamesh-PR4®, which was designed for pelvic floor repair to withstand mechanical strain. Prolift® at rest showed moderate porosity with little stretchability but complete loss of effective porosity at strain of 4.9 N/cm. Prolift + M® revealed an increased porosity at rest, but at strain showed high stretchability, with subsequent loss of effective porosity at strain of 2.5 N/cm. Dynamesh PR4® preserved its high porosity even under strain, but as consequence of limited stretchability. Though in tension free conditions Prolift® and Prolift + M® can be considered as large pore class I meshes, application of mechanical strain rapidly lead to collapse of pores. The loss of porosity at mechanical stress can be prevented by constructions with high structural stability. Assessment of porosity under strain was found helpful to define requirements for pelvic floor devices. Clinical studies have to prove whether devices with high porosity as well as high structural stability can improve the patients' outcome.}, language = {en} } @misc{Alt2014, author = {Alt, Helmut}, title = {Energiekonzept mit kurzer Br{\"u}cke zu witterungsabh{\"a}ngigen, hohen Strompreisen : KTG Jahrestagung in Stuttgart, 22.- 24. 5. 2012}, pages = {1 -- 60}, year = {2014}, language = {de} } @inproceedings{HartungHillgaertnerSchmitzetal.2014, author = {Hartung, Frank and Hillg{\"a}rtner, Michael and Schmitz, G{\"u}nter and Schuba, Marko and Adolphs, Fabian and Hoffend, Jens and Theis, Jochen}, title = {IT-Sicherheit im Automobil}, series = {AmE 2014 : Automotive meets Electronics, Beitr{\"a}ge der 5.

The novel RoboCup Logistics League Sponsored by Festo (LLSF) aims at such CPS logistic scenarios in an automation setting. A team of robots has to produce products from a number of semi-finished products which they have to machine during the game. Different production plans are possible and the robots need to recycle scrap byproducts. This way, the LLSF is a very interesting league offering a number of challenging research questions for planning, coordination, or communication in an application-driven scenario. In this paper, we outline the objectives of the LLSF and present steps for developing the league further towards a benchmark for logistics scenarios for CPS. As a major milestone we present the new automated referee system which helps in governing the game play as well as keeping track of the scored points in a very complex factory scenario.}, language = {en} } @article{HoltrupSadeghfamHeuermannetal.2014, author = {Holtrup, S. and Sadeghfam, Arash and Heuermann, Holger and Awakowicz, P.}, title = {Characterization and optimization technique for microwave-driven high-intensity discharge lamps using hot S-parameters}, series = {IEEE transactions on microwave theories and techniques}, volume = {62}, journal = {IEEE transactions on microwave theories and techniques}, number = {10}, publisher = {IEEE}, address = {New York}, issn = {0018-9480}, doi = {10.1109/TMTT.2014.2342652}, pages = {2471 -- 2480}, year = {2014}, abstract = {High-intensity discharge lamps can be driven by radio-frequency signals in the ISM frequency band at 2.45 GHz, using a matching network to transform the impedance of the plasma to the source impedance. To achieve an optimal operating condition, a good characterization of the lamp in terms of radio frequency equivalent circuits under operating conditions is necessary, enabling the design of an efficient matching network. This paper presents the characterization technique for such lamps and presents the design of the required matching network. For the characterization, a high-intensity discharge lamp was driven by a monofrequent large signal at 2.45 GHz, whereas a frequency sweep over 300 MHz was performed across this signal to measure so-called small-signal hot S-parameters using a vector network analyzer. These parameters are then used as an equivalent load in a circuit simulator to design an appropriate matching network. Using the measured data as a black-box model in the simulation results in a quick and efficient method to simulate and design efficient matching networks in spite of the complex plasma behavior. Furthermore, photometric analysis of high-intensity discharge lamps are carried out, comparing microwave operation to conventional operation.}, language = {en} } @article{AlhwarinFerreinScholl2014, author = {Alhwarin, Faraj and Ferrein, Alexander and Scholl, Ingrid}, title = {IR stereo kinect: improving depth images by combining structured light with IR stereo}, pages = {1 -- 9}, year = {2014}, language = {en} } @book{Hoever2014, author = {Hoever, Georg}, title = {Vorkurs Mathematik : Theorie und Aufgaben mit vollst{\"a}ndig durchgerechneten L{\"o}sungen. - (Springer-Lehrbuch)}, publisher = {Springer Spektrum}, address = {Berlin [u.a.]}, isbn = {978-3-642-54870-3 (Druckausg.)}, pages = {X, 292 S. : graph.

A depth image is computed by calculating the distortion of a known infrared light (IR) pattern which is projected into the scene. While these sensors are great devices they have some limitations. The distance they can measure is limited and they suffer from reflection problems on transparent, shiny, or very matte and absorbing objects. If more than one RGB-D camera is used the IR patterns interfere with each other. This results in a massive loss of depth information. In this paper, we present a simple and powerful method to overcome these problems. We propose a stereo RGB-D camera system which uses the pros of RGB-D cameras and combine them with the pros of stereo camera systems. The idea is to utilize the IR images of each two sensors as a stereo pair to generate a depth map. The IR patterns emitted by IR projectors are exploited here to enhance the dense stereo matching even if the observed objects or surfaces are texture-less or transparent. The resulting disparity map is then fused with the depth map offered by the RGB-D sensor to fill the regions and the holes that appear because of interference, or due to transparent or reflective objects. Our results show that the density of depth information is increased especially for transparent, shiny or matte objects.}, language = {en} } @inproceedings{GebhardtRitzSiekmannetal.2014, author = {Gebhardt, Andreas and Ritz, Thomas and Siekmann, Kirsten and Wallenborn, Ramona}, title = {Additive manufacturing businesses in the process chain of individualized mass products}, series = {DDMC 2014 : Proceedings of the Fraunhofer Direct Digital Manufacturing Conference}, booktitle = {DDMC 2014 : Proceedings of the Fraunhofer Direct Digital Manufacturing Conference}, editor = {Demmer, Axel}, publisher = {Fraunhofer}, address = {Stuttgart}, isbn = {978-3-8396-9128-1 (E-Book)}, year = {2014}, language = {en} } @inproceedings{RitzIzquierdoTelloDamm2014, author = {Ritz, Thomas and Izquierdo Tello, C{\´e}sar and Damm, Sebastian}, title = {Connecting a pedelec to the cloud as basis for gamification in multi modal mobility planning}, series = {MobileCloud 2014 : 2nd IEEE International Conference on Mobile Cloud Computing, Services, and Engineering Oxford, United Kingdom 7-10 April 2014}, booktitle = {MobileCloud 2014 : 2nd IEEE International Conference on Mobile Cloud Computing, Services, and Engineering Oxford, United Kingdom 7-10 April 2014}, publisher = {IEEE Service Center}, address = {Piscataway, NJ}, isbn = {978-1-4799-2504-9}, doi = {10.1109/MobileCloud.2014.25}, pages = {101 -- 108}, year = {2014}, language = {en} } @inproceedings{OegunKlingHeuermannetal.2014, author = {{\"O}gun, Celal Mohan and Kling, Rainer and Heuermann, Holger and Gr{\"a}ser, Ulrich and Schopp, Christoph}, title = {Elektrodenlose quecksilberfreie Niederdrucklampen betrieben mit Mikrowellen}, series = {Licht 2014 [Elektronische Ressource] : Den Haag, Holland ; 21.
