Grund daf{\"u}r ist der wachsende Wunsch nach unabh{\"a}ngigen Trainingsm{\"o}glichkeiten. GYMLET bietet den Sportler:innen die M{\"o}glichkeit, ihre Fitness funktional, selbstorganisiert und unabh{\"a}ngig zu trainieren. Dabei kann durch den selbstbestimmten Trainingsort neben der k{\"o}rperlichen Fitness vor allem die Motivation zur sportlichen Aktivit{\"a}t und das Wohlbefinden gesteigert werden. Unterst{\"u}tzt wird das Trainingssystem durch eine App, welche den Sportler:innen neben Nutzungsm{\"o}glichkeiten als Coach und Trainingsplaner dient. Um diese Trainingsm{\"o}glichkeit an die Zielgruppe heranzutragen, ist eine Kampagnenstrategie aus zwei Phasen entstanden. In dieser sollen Postings und Clips {\"u}ber Instagram und Youtube ver{\"o}ffentlicht werden. Zus{\"a}tzlich werden Zeitschriften und m{\"o}gliche Kooperationen mit Therapeuten oder Freizeitunterk{\"u}nften zur Ver{\"o}ffentlichung der Kampagne genutzt.}, language = {de} } @masterthesis{Buechel2021, type = {Bachelor Thesis}, author = {B{\"u}chel, Carolin}, title = {Fitnesssport: Gestaltung eines mobilen Outdoor-Trainingssystems}, publisher = {FH Aachen}, address = {Aachen}, school = {Fachhochschule Aachen}, pages = {212 Seiten}, year = {2021}, abstract = {Der Wunsch nach Gesundheit und Individualisierung der eigenen Freizeit als Ausgleich zum Alltag ist heute in der Gesellschaft so ausgepr{\"a}gt wie noch nie.

This paper introduces a validated methodology to investigate the aeroelastic instabilities of wing-propeller systems and to understand the dynamic mechanism leading to wing and whirl flutter and transition from one to the other. Factors such as nacelle positions along the wing span and chord and its propulsion system mounting stiffness are considered. Additionally, preliminary design guidelines are proposed for flutter-free wing-propeller systems applicable to novel aircraft designs. The study demonstrates how the critical speed of the wing-propeller systems is influenced by the mounting stiffness and propeller position. Weak mounting stiffnesses result in whirl flutter, while hard mounting stiffnesses lead to wing flutter. For the latter, the position of the propeller along the wing span may change the wing mode shapes and thus the flutter mechanism. Propeller positions closer to the wing tip enhance stability, but pusher configurations are more critical due to the mass distribution behind the elastic axis.}, language = {en} } @article{BoehnischBraunMuscarelloetal.2023, author = {B{\"o}hnisch, Nils and Braun, Carsten and Muscarello, Vincenzo and Marzocca, Pier}, title = {A sensitivity study on aeroelastic instabilities of slender wings with a large propeller}, series = {AIAA SCITECH 2023 Forum}, journal = {AIAA SCITECH 2023 Forum}, publisher = {AIAA}, address = {Reston, Va.}, doi = {10.2514/6.2023-1893}, pages = {1 -- 14}, year = {2023}, abstract = {Next-generation aircraft designs often incorporate multiple large propellers attached along the wingspan. These highly flexible dynamic systems can exhibit uncommon aeroelastic instabilities, which should be carefully investigated to ensure safe operation. The interaction between the propeller and the wing is of particular importance. It is known that whirl flutter is stabilized by wing motion and wing aerodynamics. This paper investigates the effect of a propeller onto wing flutter as a function of span position and mounting stiffness between the propeller and wing. The analysis of a comparison between a tractor and pusher configuration has shown that the coupled system is more stable than the standalone wing for propeller positions near the wing tip for both configurations. The wing fluttermechanism is mostly affected by the mass of the propeller and the resulting change in eigenfrequencies of the wing. For very weak mounting stiffnesses, whirl flutter occurs, which was shown to be stabilized compared to a standalone propeller due to wing motion. On the other hand, the pusher configuration is, as to be expected, the more critical configuration due to the attached mass behind the elastic axis.}, language = {de} } @article{BoehnertBlaschkeBiewendt2023, author = {B{\"o}hnert, Arno and Blaschke, Florian and Biewendt, Marcel}, title = {Impact of sustainability on the strategic direction of luxury companies}, series = {European Journal of Marketing and Economics}, volume = {6}, journal = {European Journal of Marketing and Economics}, number = {1}, publisher = {Revistia}, address = {London}, issn = {2601-8659}, pages = {70 -- 85}, year = {2023}, abstract = {Today's society is undergoing a paradigm shift driven by the megatrend of sustainability.

For this purpose, interviews were conducted with managers from the luxury industry, in which they were asked about specific measures taken by their companies as well as trends in the industry. In a subsequent evaluation, the trends in the luxury industry were summarized for the areas of ecological, social, and economic sustainability. It was found that the area of environmental sustainability is significantly more focused than the other sub-areas. Furthermore, the need for a customer survey to validate the industry-based measures was identified.}, language = {en} } @inproceedings{BoehmHellmannsBackesetal.2006, author = {B{\"o}hm, Stefan and Hellmanns, Mark and Backes, Andreas and Dilger, Klaus}, title = {Lock-in thermography based NDT of automotive parts}, series = {Proceedings of the 3rd World Congress on Adhesion and Related Phenomena : WCARP-III, October 15 -18, 2006, Beijing, China}, booktitle = {Proceedings of the 3rd World Congress on Adhesion and Related Phenomena : WCARP-III, October 15 -18, 2006, Beijing, China}, publisher = {Beijing Adhesion Society of China}, address = {Beijing}, pages = {382 -- 384}, year = {2006}, language = {en} }
