Nach der Corona-Pandemie haben Messeveranstaltungen als physische Interaktionsplattformen der Fachöffentlichkeit zu alter Stärke zurückgefunden. Die Digitalisierung erweitert die Angebote auf den Messen über Virtual Reality, Augmented Reality, Robotik und den Einsatz von künstlicher Intelligenz (KI). Bei der Programmierung von Messerobotern mit Unterstützung von KI stellt sich die Frage, wie emotional die Mensch-Roboter Interaktion gestaltet werden sollen. Aus der Forschung zur Robotik im Pflegebereich ist z. B. bekannt, dass emotional programmierte Roboter einen Zusatznutzen für die Anwender bringen. Aber gilt das auch für ein Messegespräch, in dem die emotional-menschliche Komponente Vertrauensfördernd wirket soll? Dazu wurde die folgende Forschungsfrage untersucht: „Inwiefern beeinflussen Emotionen als Teil der nonverbalen Interaktion im Rahmen der Mensch-Roboter-Interaktion die Akzeptanz von sozialen Robotern bei Messegesprächen?“ Zur Beantwortung der Forschungsfrage wurde ein Laborexperiment durchgeführt. Es wurde eine emotional und eine sachlich programmierte Version des Furhat-Roboters konzipiert, mit denen Probanden im Rahmen eines Messegesprächs interagiert haben. Nach Auswertung der Ergebnisse konnten kaum signifikanten Unterschiede in der Akzeptanz zwischen der emotionalen und der sachlichen Roboterversion festgestellt werden. Mögliche Investition in emotionale Programmierungselemente von Robotern im Messeeinsatz sollten nach diesen Ergebnissen hinterfragt werden.

As a contribution to addressing the challenges posed by climate change, acoustic ecology, and in particular the study of changes in soundscapes, provides an opportunity to better understand and subsequently manage climate change. This paper focuses on the development of new spectrogram-based analysis methods to expand the possibilities of comparative analysis of soundscapes. The database to be analysed with the new methods is provided by the WikliNathi project, a long-term monitoring study to investigate the sonic changes of populations of living organisms as well as geophone and anthropophone sounds in a nature reserve. The developed methods of analysis will be presented in detail. Selected audio recordings are analysed for changes in the sounds of great tits, grasshoppers and frogs from 2018 to 2023 using spectral flatness, temporal flatness and onset detection in aligned time-frequency regions. The evaluation of the results shows that the proposed new methods can be used to obtain more detailed and complementary results in future studies as part of this and other bioacoustic projects.

Laser sintering, also known as powder bed fusion—laser beam, employs a laser to sinter-powdered polymeric materials, such as Polyamide 12. Despite the process, a significant portion of the powder remains unsintered. However, due to elevated temperatures, material degradation occurs, altering its chemical characteristics. Industrially, a common practice involves utilizing a mixture of virgin and aged powder, with the latter having undergone multiple thermal cycles without sintering. Developing an effective powder recycling methodology is fundamental for fully realizing the potential of Polyamide 12. This work focuses the attention on reused powder to manufacture parts in Polyamide 12 through selective laser sintering and evaluates the correlation between the properties of reused powder and the strength of manufactured part through six consecutive printing processes. To achieve this, a wide experimental approach was planned and developed to arrive to establish a clear relationship between the degree of crystallinity of the powder and the ultimate tensile strength of the part made from that powder. This relationship may be used to choose the kind of powder based on the strength required to the manufactured part in exercise. At the same time, if only a kind of powder is available, this relationship allows to predict the mechanical strength of the part manufactured.

In this chapter, an overview is given of the research work during the years 2007 until 2016 in the field of tolerance analysis, optimization and synthesis of mechanisms ([11] and [17]). At the beginning, the challenges related to mechanisms are highlighted, especially the time-dependent behaviour of a mechanism during its operation and the different kinds of deviation occuring during the production and the operation of the mechanism. After that, the integrated approach for the statistical tolerance analysis of mechanisms is described. This approach is then enlarged to a complete tolerance analysis, optimization and synthesis approach before its applicability is demonstrated in a case study. The chapter will end with a summary.
