Drug screenings are essential in the development of new components, particularly for evaluating the potential of drugs to induce life-threatening pro-arrhythmias. Between 1988 and 2009, 14 drugs have been removed from the market for this reason [3]. The microelectrode array (MEA) technique is a robust tool for drug screening as it detects the field potentials (FPs) for the entire cell culture. Furthermore, the propagation of the field potential can be examined on an electrode basis. To analyze MEA measurements in detail, we have developed an open-source tool.}, language = {en} } @inproceedings{FerreinBharatheeshaSchifferetal.2019, author = {Ferrein, Alexander and Bharatheesha, Mukunda and Schiffer, Stefan and Corbato, Carlos Hernandez}, title = {TRROS 2018 : Teaching Robotics with ROS Workshop at ERF 2018; Proceedings of the Workshop on Teaching Robotics with ROS (held at ERF 2018), co-located with European Robotics Forum 2018 (ERF 2018), Tampere, Finland, March 15th, 2018}, series = {CEUR Workshop Proceedings}, booktitle = {CEUR Workshop Proceedings}, number = {Vol-2329}, issn = {1613-0073}, pages = {68 Seiten}, year = {2019}, 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{StenderRitz2003, author = {Stender, Michael and Ritz, Thomas}, title = {{\"U}berbetriebliche Ad-hoc-Anwendungsintegration im Mobile Business}, series = {Wirtschaftsinformatik 2003 : Medien, M{\"a}rkte, Mobilit{\"a}t: - Bd. 1}, booktitle = {Wirtschaftsinformatik 2003 : Medien, M{\"a}rkte, Mobilit{\"a}t: - Bd. 1}, editor = {Uhr, Wolfgang}, publisher = {Physica-Verl.}, address = {Heidelberg}, isbn = {3-7908-0111-9}, pages = {103 -- 118}, year = {2003}, language = {de} } @inproceedings{RitzStrauch2010, author = {Ritz, Thomas and Strauch, Jakob}, title = {„Offline Strategie"-Patterns f{\"u}r mobile SOA Prozesse}, series = {Mobile und ubiquit{\"a}re Informationssysteme : Technologien, Anwendungen und Dienste zur Unterst{\"u}tzung von mobiler Kollaboration ; Proceedings zur 5.

The joint between the humerus and the ulna is called humeroulnar joint and the joint between the humerus and the radius is called humeroradial joint. Lateral and medial collateral ligaments stabilize the elbow. Statistically, 2.5 out of 10,000 people suffer from radial head fractures [1]. In these fractures the cartilage is often affected. Caused by the injured cartilage, degenerative diseases like posttraumatic arthrosis may occur. The resulting pain and reduced range of motion have an impact on the patient's quality of life. Until now, there has not been a treatment which allows typical loads in daily life activities and offers good long-term results. A new surgical approach was developed with the motivation to reduce the progress of the posttraumatic arthrosis. Here, the radius is shortened by 3 mm in the proximal part [2]. By this means, the load of the radius is intended to be reduced due to a load shift to the ulna. Since the radius is the most important stabilizer of the elbow it has to be confirmed that the stability is not affected. In the first test (Fig. 1 left), pressure distributions within the humeroulnar and humeroradial joints a native and a shortened radius were measured using resistive pressure sensors (I5076 and I5027, Tekscan, USA). The humerus was loaded axially in a tension testing machine (Z010, Zwick Roell, Germany) in 50 N steps up to 400 N. From the humerus the load is transmitted through both the radius and the ulna into the hand which is fixed on the ground. In the second test (Fig. 1 right), the joint stability was investigated using a digital image correlation system to measure the displacement of the ulna. Here, the humerus is fixed with a desired flexion angle and the unconstrained forearm lies on the ground. A rope connects the load actuator with a hook fixed in the ulna. A guide roller is used so that the rope pulls the ulna horizontally when a tensile load is applied. This creates a moment about the elbow joint with a maximum value of 7.5 Nm. Measurements were performed with varying flexion angles (0°, 30°, 60°, 90°, 120°). For both tests and each measurement, seven specimens were used. Student's t-test was employed to determine whether the mean values of the measurements in native specimen and operated specimens differ significantly.}, language = {en} } @inproceedings{TeixeiraBouraNiederwestbergMcLeodetal.2016, author = {Teixeira Boura, Cristiano Jos{\´e} and Niederwestberg, Stefan and McLeod, Jacqueline and Herrmann, Ulf and Hoffschmidt, Bernhard}, title = {Development of heat exchanger for high temperature energy storage with bulk materials}, series = {AIP Conference Proceedings}, volume = {1734}, booktitle = {AIP Conference Proceedings}, number = {1}, doi = {10.1063/1.4949106}, pages = {050008-1 -- 050008-7}, year = {2016}, language = {en} } @inproceedings{BischofEyKucketal.2015, author = {Bischof, Michael and Ey, Ludger and Kuck, Alexander and Rahier, Michael and Ritz, Thomas}, title = {Nutzerzentrierte Gestaltung und Entwicklung eines kontextsensitiven HMI}, series = {Mensch und Computer 2015 : Workshop}, booktitle = {Mensch und Computer 2015 : Workshop}, editor = {Weisbecker, Anette}, publisher = {De Gruyter Oldenbourg}, address = {Berlin}, isbn = {978-3-11-044333-2}, pages = {467 -- 474}, year = {2015}, language = {de} } @inproceedings{Dahmann2011, author = {Dahmann, Peter}, title = {Stemme S10 VTX als multifunktionales Forschungsflugzeug}, series = {Deutscher Luft- und Raumfahrtkongress 2011 : Bremen, 27. bis 29.
