Im Projekt EILD.nrw wurden Open Educational Resources (OER) für die Lehre im Fach Datenbanken entwickelt. Lehrende können die Tools und Kurse in einer Vielzahl von Lernszenarien einsetzen. Studierende der Informatik und Anwendungsfächer lernen den kompletten Lebenszyklus von Datenbanken kennen. Zu diesem Zweck wurden Quizze, interaktive Tools, Lehrvideos und Kurse für Lernmanagementsysteme entwickelt und unter einer Creative Commons-Lizenz veröffentlicht.
Welche Strukturen formen die transnationale Care-Arbeit? Wie lassen sich diese Strukturen verändern? Und welche Rolle spielen die Erkenntnisse für die Selbstorganisation der Arbeiter*innen?
Ebendiese und weitere Fragen werden in der vorliegenden Arbeit analysiert, indem Erkenntnisse aus postkolonial-feministischen Theorien mit Theorien der sozialen Bewegungsforschung verknüpft werden. Insofern bildet die Arbeit die individuelle und kollektive Handlungsfähigkeit von marginalisierten Gruppen ab und verortet diese innerhalb gesellschaftlicher Machtstrukturen, die ihre Möglichkeiten bedingen und eingrenzen.

A numerical study is carried out meticulously to scrutinize the impact of different shapes of chimneys like circular (outer dia, dc), convergent (outer dia, 0.5dc), divergent (outer dia, 1.5dc), sudden contraction (outer dia, 0.5dc), and sudden expansion (outer dia, 1.5dc) on the performance of an SCPP. 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.
Nachhaltigkeit als transdisziplinäre Herausforderung für Nonprofit-Organisationen – Eine Einführung
(2023)
Over the past decades, research in room acoustics has established several derivative measures of an impulse response, some of which are incorporated in the ISO 3382 standards. These parameters intend to represent perceptual qualities, but were developed without a consistent modeling of room acoustical perception. More recent research proposed comprehensive inventories of room acoustic perception that are purely based on evaluations by human subjects, such as the Room Acoustical Quality Index (RAQI). In this work RA-QI scores acquired for 70 room impulse responses were predicted from room acoustical parameters. Except for Reverberance, the prediction of RAQI factors performed rather poor. In most cases, the sound source had a greater impact on RAQI scores. All analyses are published in an online tool, where users can upload omnidirectional and binaural impulse responses, and instantly obtain and visualize several physical descriptors, as well as predicted RAQI scores for three different sound sources. So far, acceptable prediction accuracy is achieved for Reverberance, Strength, Irregular Decay, Clarity and Intimacy. Larger data sets of evaluated impulse responses are required to improve the model performance and enable reliable predictions of room acoustical quality. Therefore, the administration of RAQI evaluations within the website is currently being developed.
