Thus, we argue that, on a perceptual level, reverberation basically breaks down into interaural differences and spectro-temporal cues and that the separation of a perceived timbre into a sound source and a surrounding room is a purely cognitive process. To investigate the connection between the perception of reverberation cues and timbre analysis, the sensitivity for changes in reverberation was compared to timbre perception abilities. The Timbre Perception Test was used to measure the perception of the temporal envelope, spectral centroid, and spectral flux of artificial sounds. Sensitivity for changes in reverberation time was tested with a discrimination task using speech and noise with speech-alike spectral and temporal envelopes as source signals. Musical and acoustical expertise was assessed through the Goldsmiths Musical Sophistication Index and self-reports on experience with and knowledge of acoustics. There was a considerable correlation between timbre and reverberance perception ability, but timbre perception and academic experience predicted only 41\% of the variance in reverberance perception. Still, perception abilities related to similar acoustical phenomena seem to be better indicators of listening skills than self-reports on acoustical or musical expertise.}, language = {en} } @misc{BuchClaasEilertetal.2022, author = {Buch, Susanne and Claas, Oliver and Eilert, Eva and Fliegner, Angelika and Raatz, Philip and Reiter, Martin and Schick, Elena and Slowig, Benjamin}, title = {Hochschul{\"u}bergreifende Zusammenarbeit gestalten: FDMScouts.nrw}, publisher = {Zenodo}, doi = {10.5281/zenodo.7100472}, year = {2022}, abstract = {Im Rahmen des 55.

These are web applications with "super-powers" which are meant to provide the kinds of user experiences previously only native mobile applications could. Therefore they are able to match native applications in their capabilities but still thrive on the reachability of the web. They achieve this by implementing certain characteristics which originate from innovative standards and sophisticated best practices. Conveniently, as it is the web, PWAs are working seamlessly cross-platform. One of the closest things to a PWA so far may be an application created with the NativeScript framework. Such an application is also developed with web technologies yet able to use any native interface directly. This is made possible by using a designated runtime for mediating between JavaScript and the mobile system. Eventually, NativeScript is able to offer a high degree nativity yet also of convenient abstraction during development. This paper is set out to deliver further insight into both approaches by contrasting them based on the characteristics of PWAs. For this purpose, these characteristics are elaborated and adjusted to be applicable to native mobile applications. Hence a reasonable basis for what to expect from a native application is derived. Then NativeScript is assessed on this basis by the means of transferable concepts and technologies as well as a prototypic mobile application. Finally, an informed discussion and conclusion is performed based on the results. The comprehensive characteristics of PWAs resolve previous shortcomings with well thought out concepts and new technologies. These are transferable to native mobile applications to a far extent and may also be put into practice with NativeScript. The framework's approach may be very well called ingenious, however, in the long run it might fall short of the innovative concept of PWAs. Having said this, it is still able to serve as a practical measure for creating appealing user experiences for multiple systems with arguably little effort. Due to large overlap a transformation between the two application types is a realistic option. Either way, web technologies are far from what they used to be and it is exciting to see how the mobile and web landscape will evolve in the future.}, language = {en} } @techreport{WeidekampMaicherWojciechowskiTylletal.2021, author = {Weidekamp-Maicher, Manuela and Wojciechowski, Manfred and Tyll, Susanne and Drewniok, Arthur and Helmes, Ina and Pohlmann, Wolf Eric}, title = {Technikberatung als Baustein der Wohnberatung: Erfahrungen, Rahmenbedingungen und aktuelle Entwicklungstrends}, address = {D{\"u}sseldorf}, organization = {Hochschule D{\"u}sseldorf}, isbn = {978-3-941334-33-5}, doi = {10.20385/978-3-941334-33-5}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:due62-opus-29827}, pages = {213}, year = {2021}, subject = {Wohnberatung}, language = {de} } @misc{OPUS4-3648, title = {Forschungsreport 2021}, editor = {Wojciechowski, Manfred}, address = {D{\"u}sseldorf}, organization = {Hochschule D{\"u}sseldorf}, doi = {10.20385/opus4-3648}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:due62-opus-36487}, pages = {224}, year = {2022}, language = {de} } @misc{OPUS4-2902, title = {Forschungsreport 2020}, editor = {Wojciechowski, Manfred}, publisher = {Hochschule D{\"u}sseldorf}, address = {D{\"u}sseldorf}, organization = {Hochschule D{\"u}sseldorf}, doi = {10.20385/opus4-2902}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:due62-opus-29023}, pages = {200}, year = {2021}, abstract = {Der Forschungsreport 2020 ist in bew{\"a}hrter Form in die drei großen Themenbereiche der HSD gegliedert: Gesellschaft \& Kultur, Technik, Umwelt \& Energie sowie Kommunikation \& Medien.

Furthermore, capturing talents' height can also be used to adjust the parameters of elements in the virtual environment, like the position and scaling of a virtual display. In addition to the talents, a rigid body was tracked as placeholder for graphics, easing the interaction tasks for a talent.

A Eulerian-Lagrangian formulation is used to describe the two-phase flow. Turbulence is modelled within a RANS (Reynolds averaged numerical simulation) framework. Four turbulence viscosity- (TV) based models, namely the standard k-ε model, realizable k-ε model, renormalization group theory k-ε model, and the shear stress transport k-ω model are used. In addition, a Reynolds stress transport model (RSM) is employed. The models are assessed by comparing the predicted velocity fields with the measurements of other authors. In terms of overall average values, the agreement of the predictions to the measurements is observed to be within the range 20-40\%. A better performance of the RSM compared to the TV models is observed, with a nearly twice as better overall agreement to the experiments, particularly for the swirl velocity. In the second part of the investigation, the resolution of the discrete particle phase in modelling the turbulent particle dispersion (TPD) and particle size distribution (SD) is investigated. Using the discrete random walk model for the TPD, it is shown that even five random walks are sufficient for an accuracy that is quite high, with a less than 1\% mean deviation from the solution obtained by thirty random walks. The approximation of the measured SD is determined by a continuous Rosin-Rammler distribution function, and inaccuracies that can occur in its subsequent discretization are demonstrated and discussed. An investigation on the resolution of the SD by discrete particle size classes (SC) indicates that 12 SC are required for an accuracy with a less than 1\% mean deviation from the solution with 18 SC.

The blood flows in two different hardshell reservoirs are computationally investigated. A special emphasis is placed on the prediction of an onset of transition and turbulence generation. Reynolds-averaged numerical simulations (RANS) based on a transitional turbulence model, as well as large eddy simulations (LES) are applied to achieve an accurate prediction. In the LES analysis, the non-Newtonian behavior of the blood is considered via the Carreau model. Blood damage potential is quantified applying the Modified Index of Hemolysis (MIH) based on the predicted flow fields. The results indicate that the flows in both reservoirs remain predominantly laminar. For one of the reservoirs, considerable turbulence generation is observed near the exit site, caused by the specific design for the connection with the drainage tube. This difference causes the MIH of this reservoir to be nearly twice as large as compared to the alternative design.
