In this paper we presented the results of the workshop with the topic: Co-creation in citizen science (CS) for the development of climate adaptation measurements - Which success factors promote, and which barriers hinder a fruitful collaboration and co-creation process between scientists and volunteers? Under consideration of social, motivational, technical/technological and legal factors., which took place at the CitSci2022. We underlined the mentioned factors in the work with scientific literature. Our findings suggest that a clear communication strategy of goals and how citizen scientists can contribute to the project are important. In addition, they have to feel include and that the contribution makes a difference. To achieve this, it is critical to present the results to the citizen scientists. Also, the relationship between scientist and citizen scientists are essential to keep the citizen scientists engaged. Notification of meetings and events needs to be made well in advance and should be scheduled on the attendees' leisure time. The citizen scientists should be especially supported in technical questions. As a result, they feel appreciated and remain part of the project. For legal factors the current General Data Protection Regulation was considered important by the participants of the workshop. For the further research we try to address the individual points and first of all to improve our communication with the citizen scientist about the project goals and how they can contribute. In addition, we should better share the achieved results.
Ausbildung in der Akustik
(2022)
Die Wissenschaft der Akustik mit ihrer Vielfallt und Interdisziplinarität bietet hervorragende Möglichkeiten an beruflichen Betätigungsfeldern und hat viele von uns in ihren Bann gezogen. Ausbildung in der Akustik bedeutet mehr als Studierenden nur Wissen und Fähigkeiten zu vermitteln. Eigentlich ist nach dem Studium auch der Lernprozess nicht abgeschlossen, sondern wie viele Akustiker:innen meinen, fängt dieser erst dann richtig an. Um eine sehr gute Ausbildung zu gestalten, bedarf es neben Vorbildern an Personen auch Lehrformate, Methoden und Tools. Die folgenden sechs Kurzbeiträge sind Beispiele gelungener Maßnahmen in der Ausbildung der Akustik und sollen anregen, die Qualität in der Lehre stetig zu verbessern.
A new planar compact antenna composed of two crossed Cornu spirals is presented. Each Cornu spiral is fed from the center of the linearly part of the curvature between the two spirals, which builds the clothoid. Sequential rotation is applied using a sequential phase network to obtain circular polarization and increase the effective bandwidth. Signal integrity issues have been addressed and designed to ensure high quality of signal propagation. As a result, the antenna shows good radiation characteristics in the bandwidth of interest. Compared to antennas of the same size in the literature, it is broadband and of high gain. Although the proposed antenna has been designed for K- and Ka-band operations, it can also be developed for lower and upper frequencies because of the linearity of the Maxwell equations.
