Furthermore, the parametric impact with different chimney divergence angles (CDA, ϕ), and ground absorber slope angle (GSA, γ) on the SCPP performance is also scrutinized. Optimum divergence angle (ϕ=+0.75◦) enhances the power generation up to ~ 47\% (76 kW) with a horizontal ground absorber surface. An increase or decrease in CDA lessens the power generation. With a sloped ground absorber angle γ=0.6◦, the gain in power generation is 60\% (82 kW). The study of combination of ground sloped absorber (γ=0.6◦) and divergent chimney (ϕ=+0.75◦) shows enhancement of the power generation upto 80\% (92 kW) more than the classical Manzaranes plant.}, language = {en} } @techreport{Deckert2024, author = {Deckert, Carsten}, title = {Good Vibrations from Electronic Circuits: The Technological Development of the Synthesizer}, issn = {2941-4075}, doi = {10.20385/opus4-4439}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:due62-opus-44394}, pages = {28}, year = {2024}, language = {en} } @article{BarbashovGellingsOezenetal.2024, author = {Barbashov, Maksim and Gellings, Markus and {\"O}zen, Semih and Jahr, Andreas}, title = {Hochgeschwindigkeitsverschleißtests an Scheibenm{\"a}hwerkmessern verschiedener Hersteller nach der Verschleißtopfmethode}, series = {Agricultural engineering.eu}, volume = {79}, journal = {Agricultural engineering.eu}, number = {2}, publisher = {Kuratorium f{\"u}r Technik und Bauwesen in der Landwirtschaft e.

These knives are therefore exposed to high levels of wear and tear, and will also be ofen changed because of loss of material by bad cutting quality. That is why it is interesting to save costs during manufacturing in spite of a correspondingly long service life. This research records the current manufacturing quality of the mower blades and examines how they behave in comparison. Based on the obtained results, further decisions on the methods, procedures and ways of extending the life of the disc mower blades should be proposed. For the investigations, a test bench based on a wear pot was used. The wear that occurs on the blade is determined using several parameters and compared accordingly. The parameters of the test setup determined as a result of the test can be used for further studies of wear resistance.}, language = {en} } @misc{OPUS4-4468, title = {961 - Vierte Satzung zur {\"A}nderung der Pr{\"u}fungsordnung f{\"u}r den weiterbildenden Masterstudiengang Taxation an der Hochschule D{\"u}sseldorf vom 03.07.2024}, address = {D{\"u}sseldorf}, organization = {Hochschule D{\"u}sseldorf}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:due62-opus-44683}, pages = {2}, year = {2024}, abstract = {Aufgrund der \S\S 2 Abs. 4, 64 Abs. 1 des Gesetzes {\"u}ber die Hochschulen des Landes Nordrhein-Westfalen (Hochschulgesetz - HG) vom 16.09.2014 (GV.

This research employed the Experience Sampling Method via the smartphone app MuPsych to continuously capture real-time data on individuals' music listening behaviors and related emotional responses. Over a span of two weeks, participants from Germany were prompted to report on various factors as they engaged in music listening, resulting in a rich dataset. Results indicate that Spotify Premium was the most frequently used music application, with personal playlists being the preferred listening format. To unravel the intricacies of these responses and their determinants, linear mixed-effects model analysis was utilized. Among the critical findings, the Perceived Usefulness and Perceived Ease of Use, two of the central constructs of the Technology Acceptance Model, emerged as significant predictors for the valence and enjoyment of the music experienced by users during the onset of music listening sessions. This highlights the imperative role of user-friendly interfaces in enhancing positive emotional states even before fully engaging with the music, underscoring the need for designers and developers of music-related apps to prioritise usability and useful functions.}, language = {en} } @article{GeerkensSieberichsBraunetal.2024, author = {Geerkens, Simon and Sieberichs, Christian and Braun, Alexander and Waschulzik, Thomas}, title = {QI²: an interactive tool for data quality assurance}, series = {AI and Ethics}, volume = {4}, journal = {AI and Ethics}, publisher = {Springer Nature}, issn = {2730-5961}, doi = {10.1007/s43681-023-00390-6}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:due62-opus-42945}, pages = {141 -- 149}, year = {2024}, abstract = {The importance of high data quality is increasing with the growing impact and distribution of ML systems and big data.

Durch die Beteiligung m{\"o}glichst vieler B{\"u}rger am politischen Diskurs kann ein neuer inklusiver und vielstimmiger Kommunikationsraum geschaffen werden, in dem die pluralen, vielschichtigen Stimmen der Gesellschaft {\"u}ber die pers{\"o}nlichen Kommunikationsnetzwerke der Einzelnen hinaus in den Austausch treten und so Koorientierung erm{\"o}glicht wird. Doch in der Forschung gibt es unterschiedliche Deutungen, ob und inwieweit diese Potenziale eingel{\"o}st werden. Der vorliegende Beitrag analysiert basierend auf einer Onlinebefragung die Teilhabe an verschiedenen Formen der Anschlusskommunikation aus einer Milieuperspektive. Die Befunde zeigen, dass die Muster der Anschlusskommunikation sich mit den Ergebnissen der sonstigen Kommunikationspraktiken in den politisch-kommunikativen Milieus decken. Ein politisch selbstbewusstes, engagiertes und informiertes Milieu nutzt besonders die proaktiven M{\"o}glichkeiten der Anschlusskommunikation, um Meinungen zu debattieren und auszutauschen. Ein sich in der kommunikativen Teilhabe zur{\"u}ckhaltendes Milieu partizipiert in ebenso geringem Maße an der Anschlusskommunikation und koppelt sich so von einem integrierten Kommunikationsraum ab. Sich abschottende Milieus legen einen starken Fokus auf reaktive Formen der Anschlusskommunikation, die zur permanenten Affirmation eigener Ansichten genutzt werden. Diese unterschiedliche Nutzung tr{\"a}gt dazu bei, dass gesellschaftliche Spaltungstendenzen eher best{\"a}rkt statt reduziert werden.}, language = {de} } @misc{OPUS4-4502, title = {965 - Erste Satzung zur {\"A}nderung der Pr{\"u}fungsordnung (studiengangspezifische Bestimmungen) f{\"u}r den Masterstudiengang Kommunikations-, Multimedia- und Marktmanagement an der Hochschule D{\"u}sseldorf vom 23.07.2024}, address = {D{\"u}sseldorf}, organization = {Hochschule D{\"u}sseldorf}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:due62-opus-45022}, pages = {2}, year = {2024}, abstract = {Aufgrund der \S\S 2 Abs. 4, 64 Abs. 1 des Gesetzes {\"u}ber die Hochschulen des Landes Nordrhein-Westfalen (Hochschulgesetz - HG) vom 16.09.2014 (GV.
