The aim of this article is to evaluate the effectiveness of using a Myo control armband and the Kinect 2 for recognition of gestures in order to interact with virtual objects in a weather report scenario. The Myo armband has an inertial measurement unit and is able to read electrical activity produced by skeletal muscles, which can be recognized as gestures, which are trained by machine learning. A Kinect sensor was used to build up a dataset which contains motion recordings of 8 different gestures and was also build up by a gesture training machine learning algorithm. Both input methods, the Kinect 2 and the Myo armband, were evaluated with the same interaction patterns in a user study, which allows a direct comparison and reveals benefits and limits of each technique.}, language = {en} } @article{BaeklerHehlNester2011, author = {Baekler, Peter and Hehl, Friedrich W. and Nester, James M.}, title = {Poincar{\´e} gauge theory of gravity: Friedman cosmology with even and odd parity modes: Analytic part}, series = {Physical Review D}, volume = {83}, journal = {Physical Review D}, number = {2}, publisher = {APS}, doi = {10.1103/physrevd.83.024001}, year = {2011}, language = {en} } @article{BaeklerHehl2011, author = {Baekler, Peter and Hehl, Friedrich W.}, title = {Beyond Einstein-Cartan gravity: quadratic torsion and curvature invariants with even and odd parity including all boundary terms}, series = {Classical and Quantum Gravity}, volume = {28}, journal = {Classical and Quantum Gravity}, number = {21}, publisher = {IOP}, doi = {10.1088/0264-9381/28/21/215017}, year = {2011}, language = {en} } @article{BaeklerHehl2006, author = {Baekler, Peter and Hehl, Friedrich W.}, title = {ROTATING BLACK HOLES IN METRIC-AFFINE GRAVITY}, series = {International Journal of Modern Physics D}, volume = {15}, journal = {International Journal of Modern Physics D}, number = {5}, publisher = {World Scientific}, doi = {10.1142/s0218271806008589}, pages = {635 -- 668}, year = {2006}, language = {en} } @inproceedings{BackesFaberAnthrakidisetal.2008, author = {Backes, Klaus and Faber, Christian and Anthrakidis, Anette and Ille, Fabian and Adam, Mario and Schramm, Sebastian}, title = {A small scale Combined Cooling, Heating and Power System}, series = {World Renewable Energy Congress X and Exhibition, 19-25.07.2008, Glasgow}, booktitle = {World Renewable Energy Congress X and Exhibition, 19-25.07.2008, Glasgow}, editor = {WREN,}, address = {Glasgow}, year = {2008}, language = {en} } @inproceedings{BackesAdamWirthetal.2018, author = {Backes, Klaus and Adam, Mario and Wirth, Hans Peter and G{\"o}tzelmann, Dennis and Helbig, Sonja and Eggert, Daniel}, title = {Efficient Design of Solar Assisted Heating Systems for Multi-Family Houses}, series = {Proceedings of EuroSun 2018, 12th International Conference on Solar Energy for Buildings and Industry, 10.-13.09.2018, Rapperswil / Switzerland, International Solar Energy Society}, booktitle = {Proceedings of EuroSun 2018, 12th International Conference on Solar Energy for Buildings and Industry, 10.-13.09.2018, Rapperswil / Switzerland, International Solar Energy Society}, editor = {H{\"a}berle, Andreas}, publisher = {International Solar Energy Society}, address = {Freiburg}, isbn = {978-3-9820408-0-6}, doi = {10.18086/eurosun2018.01.02​}, pages = {1 -- 9}, year = {2018}, language = {en} } @inproceedings{AytenHerderVonolfen2010, author = {Ayten, H{\"u}seyin and Herder, Jens and Vonolfen, Wolfgang}, title = {Visual Acceptance Evaluation of Soft Shadow Algorithms for Virtual TV Studios}, series = {HC '10 Proceedings of the 13th International Conference on Humans and Computers}, booktitle = {HC '10 Proceedings of the 13th International Conference on Humans and Computers}, publisher = {University of Aizu Press}, address = {Aizu-Wakamatsu}, pages = {66 -- 71}, year = {2010}, abstract = {Shadows in computer graphics are an important rendering aspect for spatial objects. For realtime computer applications such as games, it is essential to represent shadows as accurate as possible. Also, various tv stations work with virtual studio systems instead of real studio sets. Especially for those systems, a realistic impression of the rendered and mixed scene is important. One challenge, hence, is the creation of a natural shadow impression. This paper presents the results of an empirical study to compare the performance and quality of different shadow mapping methods. For this test, a prototype studio renderer was developed. A percentage closer filter (pcf) with a number of specific resolutions is used to minimize the aliasing issue. More advanced algorithms which generate smooth shadows like the percentage closer soft shadow (pcss) method as well as the variance shadow maps (vsm) method are analysed. Different open source apis are used to develop the virtual studio renderer, giving the benefit of permanent enhancement. The Ogre 3D graphic engine is used to implement the rendering system, benefiting from various functions and plugins. The transmission of the tracking data is accomplished with the vrpn server/client and the Intersense api. The different shadow algorithms are compared in a virtual studio environment which also casts real shadows and thus gives a chance for a direct comparison throughout the empirical user study. The performance is measured in frames per secon}, language = {en} } @article{AslanTaymazBenim2015, author = {Aslan, Erman and Taymaz, Imdat and Benim, Ali Cemal}, title = {Investigation of LBM curved boundary treatments for unsteady flows}, series = {European Journal of Mechanics -

A bulk Cu/Co ratio of ~2 was found to be most suitable in terms of activity and product distribution. Surface enrichment of Mo for all samples was observed by XPS, which significantly influenced the performance of the catalysts. Mo was found to be both a structural and a chemical promoter. Strong metal-support interactions were further achieved by modification of alumina with magnesia.
