Unfortunately, the more functions are available, the less they are accessible to the average user. The design of the user interface suffers from a lack of suitability for the tasks, does not conform to user expectations and a suboptimal self-descriptiveness. The usability of modern mobile phones was tested in a broad survey with over 1300 participants. An internet based simulation offered tasks and an online evaluation. It could be pointed out that mobile phones are not only hard to access for novices but also those who consider themselves experts have difficulties when confronted with unknown functions or another brand of phone. Approaches to increase the usability are discussed.}, language = {en} } @inproceedings{deBanffyHall2014, author = {de B{\´a}nffy-Hall, Alicia}, title = {Bridging Scholarship and Practice in Community Music through Action Research}, series = {CMA XIV: Listening to the World: Experiencing and Connecting the Knowledge from Community Music Proceedings from the International Society for Music Education}, booktitle = {CMA XIV: Listening to the World: Experiencing and Connecting the Knowledge from Community Music Proceedings from the International Society for Music Education}, editor = {Cohen, Mary}, address = {Salvador, Brazil}, isbn = {978-0-9942044}, pages = {94 -- 101}, year = {2014}, language = {en} } @inproceedings{HelmPugachevNeef2008, author = {Helm, Peter and Pugachev, Alexander and Neef, Matthias}, title = {Breaking the Swirl With Brush Seals: Numerical Modeling and Experimental Evidence}, series = {Proceedings of the ASME Turbo Expo 2008 : presented at the 2008 ASME Turbo Expo, June 9 - 13, 2008, Berlin, Germany}, volume = {4}, booktitle = {Proceedings of the ASME Turbo Expo 2008 : presented at the 2008 ASME Turbo Expo, June 9 - 13, 2008, Berlin, Germany}, publisher = {ASME}, address = {New York}, organization = {American Society of Mechanical Engineers Corporation; International Gas Turbine Institute Corporation}, isbn = {978-0-7918-4314-7}, doi = {10.1115/GT2008-50257}, pages = {1387 -- 1396}, year = {2008}, abstract = {Striving for smaller losses in turbomachinery has led to many advancements in the design of seals. Modern sealing concepts such as brush seals hold a great potential to increase the efficiency of both flight engines and stationary turbines. At the same time, in order to maintain stable operating conditions of the rotor, swirl-induced forces must be kept at a minimum in the sealing channels. Therefore, the influence of the permeable and flexible bristle pack of brush seals on the flow around the rotor surface must be known. In this paper the swirl flow in the cavities of two different seal geometries is studied experimentally and numerically. A conventional three-tooth labyrinth serves as a reference. A second seal arrangement with a bristle pack upstream of two teeth is compared with the reference labyrinth. The swirl is evaluated experimentally from total and static pressure measurements in various axial and circumferential positions. Additionally, the axial swirl distribution is calculated using computational fluid dynamics (CFD). Here, the numerical model of the brush seal is based on the porous medium approach and is calibrated using the experimental values of the leakage and the bristle clearance by adjusting the thickness of the bristle pack. The calibrated CFD model is then used to study the impact of the brush seal on the swirl component of the sealing flow. The observed significant decrease of the swirl by the brush seal shows good agreement with the experimental data. The impact of changes in bristle pack clearance on the swirl is also investigated and compared with experimental evidence. The aim is to show that the brush seals have a natural tendency to interrupt seal swirl. They can therefore be used for swirl control in order to create a beneficial impact on the dynamic stability of turbomachines.}, language = {en} } @article{KochOstermannSteinhageetal.2015, author = {Koch, Sabine C. and Ostermann, Thomas and Steinhage, Anna and Kende, Philip and Haller, Karl and Chyle, Fabian}, title = {Breaking barriers: Evaluating an arts-based emotion regulation training in prison}, series = {The Arts in Psychotherapy}, volume = {42}, journal = {The Arts in Psychotherapy}, publisher = {Elsevier}, doi = {10.1016/j.aip.2014.10.008}, pages = {41 -- 49}, year = {2015}, language = {en} } @article{ChyleOstermannBoehm2018, author = {Chyle, Fabian and Ostermann, Thomas and Boehm, Katja}, title = {Body- and movement-based interventions with male offenders - a narrative review}, series = {International Journal of Comparative and Applied Criminal Justice}, volume = {42}, journal = {International Journal of Comparative and Applied Criminal Justice}, number = {4}, publisher = {Taylor \& Francis}, issn = {0192-4036}, doi = {10.1080/01924036.2017.1364278}, pages = {359 -- 375}, year = {2018}, 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{Franz1996, author = {Franz, J{\"u}rgen}, title = {Benefits of Communication Methods in Environmental Protection}, series = {IETE Technical Review}, volume = {13}, journal = {IETE Technical Review}, number = {3}, publisher = {Taylor \& Francis}, doi = {10.1080/02564602.1996.11416600}, pages = {153 -- 162}, year = {1996}, language = {en} } @techreport{DeckertBussHasencleveretal.2016, author = {Deckert, Carsten and Buß, Mareike and Hasenclever, Stephanie and M{\"a}ckel, Frederic and Nyssen Guill{\´e}n, Viola and Silverio, Isabell and Wegner, Eileen}, title = {Beer Picking Game - Entwicklung und Realisierung eines Planspiels zur Simulation eines Kommissionierbereichs}, series = {CBS Working Paper Series}, volume = {2}, journal = {CBS Working Paper Series}, publisher = {Cologne Business School}, address = {K{\"o}ln}, organization = {Cologne Business School}, year = {2016}, language = {en} } @techreport{DeckertRehbergRuetten2017, author = {Deckert, Carsten and Rehberg, David and R{\"u}tten, Pia}, title = {Beer Inventory Game: Entwicklung und Realisierung eines Planspiels zur Simulation selektiver Lagerhaltungsstrategien im Distributionsnetzwerk}, series = {CBS Working Paper Series}, volume = {3}, journal = {CBS Working Paper Series}, publisher = {Cologne Business School}, address = {K{\"o}ln}, organization = {Cologne Business School}, doi = {10.13140/RG.2.2.31366.88641}, year = {2017}, language = {en} }
