More or less visible, wireless sensor networks are already applied in many aspects of our lives and for different purposes. During the 20 years of Fachgespr{\"a}ch Sensornetze (FGSN) we were able to observe the process of the birth and evolution of wireless sensor networks. What do they look like now, from that time perspective? Is there still room for research andimprovements? Or are they maybe already that mature that everything has already been said? And what do they look like from the industry point of view? What is the future of sensor networks? Where are they heading? These retrospective and perspective views are the central topic of the 20th edition of the Fachgespr{\"a}ch Sensornetze (FGSN 2023) held on the 4th of September 2023 at Hasso-Plattner-Institut as part of the NetSys 2023 conference in Potsdam. We were happy to meet again, to discuss these subjects within the scientific community. The aim of this series of Fachgespr{\"a}ch is to give scientists from academia and industry the opportunity for an informal exchange of ideas and to strengthen cooperation in this multidisciplinary research area.}, subject = {Wireless sensor networks; Sensor; Netzwerk; Kongress ; Applications; Drahtlose Sensornetze; Anwendungen; Forschung; Research}, language = {en} } @inproceedings{OPUS4-6523, title = {Utopia Kulturelle Bildung : Kunst, Medien und Kultur in der Transformationsregion Lausitz - Tagungsband}, editor = {Menrath, Stefanie Kiwi and Damm, Nadja and Media To Be (M2B) e.V.,}, doi = {10.26127/BTUOpen-6523}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:co1-opus4-65239}, year = {2023}, abstract = {Die Publikation versammelt die Ergebnisse der Veranstaltung „Utopia Kulturelle Bildung: Kunst, Medien und Kultur in der Transformationsregion Lausitz", die im Juni 2023 vom Fachgebiet „Medienp{\"a}dagogik: {\"A}sthetische Praxis in der Sozialen Arbeit" der BTU Cottbus-Senftenberg in Kooperation mit dem gemeinn{\"u}tzigen Verein M2B e.V. durchgef{\"u}hrt wurde.

From his extensive architectural oeuvre, a group of six church buildings with geometrically complex forms stands out, recognised by architectural historians as particularly innovative and influential. These churches, located in Bohemia (Czech Republic), and often collectively referred to as the 'radical', 'dynamic', 'Guarinesque', or simply 'Bohemian' group, are: St. Joseph in Obořiště (1702-11), the Castle Church in Smiřice (1702-11), St. Nicholas in the Lesser Town of Prague (1703-11), St. Clare in Cheb (1707-11), St. Margaret in Břevnov (1708-16), and the Church of the Holy Assumption in Nov{\´a} Paka (1709-24). The brick vaults of these six buildings, sequences of oval domes and double-curved vault areas, are of particular interest for building research. In this study, the geometric design of the vaults of Dientzenhofer's 'radical' churches is documented, analysed, and compared using 3D laser scans of the buildings as primary source. The 3D models generated from the scans enable a geometric analysis through the method of reverse geometric engineering, breaking down the vaults' complex three-dimensional forms into their basic two-dimensional components: segments of circles with different radii and orientations, curved in one or two directions. These forms can be found in the architectural and stereotomic treatises that were widespread at the time. By comparing the vault geometry of the six churches with each other and with the geometric concepts discussed in the treatises, general statements can be made about the architect's design choices. On the basis of this investigation, hypotheses are made about the design and underlying geometric ideas of the vaults of Dientzenhofer's 'radical group', and the results are placed in context.}, subject = {Geometric Design; Brick Vault; Christoph Dientzenhofer; Reverse Engineering; Stereotomy; Geometrischer Entwurf; Backsteingew{\"o}lbe; Reverse Engineering; Stereotomie; Dietzenhofer, Christoph; Kirchenbau; Baugestaltung; Gew{\"o}lbe; Ziegel; Geometrie; Dreidimensionales Modell}, language = {en} } @inproceedings{PechmannHagelauerWengeretal.2023, author = {Pechmann, Stefan and Hagelauer, Amelie and Wenger, Christian and Reichenbach, Marc}, title = {1.

Measures of electrocortical and neurovascular brain activity are quantified to provide a dynamic representation of the psychological state of the user, with respect to cognitions, emotions and motivation. As such, NAT can access unique aspects of human information processing, and human intelligence, which can subsequently be used to enable more versatile and more human-like forms of machine intelligence. Current trends in different scientific fields indicate an increased interest in integrating context-sensitive information from the human brain into Artificial Intelligence. NAT'22, the Neuroadaptive Technology Conference 2022, was intended to bring scientists interested in Physiological Computing, Applied Neurosciences and Passive Brain-Computer Interfaces together with experts from the fields of Artificial Intelligence, Machine Learning and Intelligent Systems. The main goals of the conference were an exchange of research questions and findings from these fields and the identification of common goals and joint ventures in the domain of Neuroadaptive Technology, including: real-time signal processing, unsupervised vs. supervised ML, designing neuroadaptive interaction, explainable AI (XAI), neuroadaptive applications, hybrid AI systems (DL + symbolic AI) for applied neurosciences, ethics of neurotechnology in real world (responsibility for action, security), cloud-based solutions for data management and more. NAT'22 was held in L{\"u}bbenau, near Berlin, and organised by the Society for Neuroadaptive Technology.

The building, a popular pilgrimage church, is known in the history of art and architecture as a Late Baroque jewel with a curious design and famous frescoes. While the shape of the building and its vault has led to different interpretations in the past, its geometry has not yet been analysed on a reliable basis. Moreover, the construction of the brick vault has not yet been subject to scientific research. In order to investigate these aspects, a 3D laser scan of the vault's extrados and intrados was utilised as the primary source. The 3D model generated from the scan not only enabled the detailed description of structural ribs, brick patterns and construction details on the extrados, but also made a geometrical analysis using reverse geometric engineering possible. The results show a geometric design of the vault surfaces as well as double-curved arches based on simple plane circle segments. This clear geometric definition of the vault is associated with a remarkable simplicity of construction method and centering. In the context of other vault designs by members of the Dientzenhofer professional circle of master builders and architects, the vault of St. Hedwig can be seen as both a continuation and an improvement in terms of geometric design and construction details.}, subject = {Kilian Ignaz Dientzenhofer; Legnickie Pole; Geometric design; Construction; Vault; Geometrischer Entwurf; Konstruktion; Gew{\"o}lbe; Dientzenhofer; Kilian Ignaz; Wahlstatt (Liegnitz); Kirchenbau; Gew{\"o}lbe; Dreidimensionale Rekonstruktion; Geometrie}, language = {en} } @inproceedings{OPUS4-5998, title = {21st EEEIC International Conference on Environment and Electrical Engineering - Student Edition : Wrocław - Ostrava - Cottbus, June 2022}, editor = {Schwarz, Harald and Janik, Przemysław and Gono, Radomir and Lehmann, Dirk}, isbn = {978-3-940471-71-0}, doi = {10.26127/BTUOpen-5998}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:co1-opus4-59982}, year = {2022}, abstract = {In the time of increased awareness about the environment problems by the public opinion and also intensive international efforts to reduce emissions of greenhouse gases, as well increase of the generation of electrical energy to facilitate industrial growth, the conference offers broad contribution towards achieving the goals of diversification and sustainable development.

In addition, this development results in a decreasing system inertia, which is expected to yield faster frequency dynamics. Therefore power-electronics-interfaced units have to take over system control tasks and, in particular, frequency control. For this purpose, accurate and fast estimation algorithms for time-varying frequency signals are needed. Motivated by this fact, we propose a time-varying parameter estimator and a tuning criterion, which for sufficiently small initial estimation errors allows to reconstruct the time-varying frequency signal of a symmetric three-phase waveform in finite time. The proposed estimator is derived by using a time-varying version of the super twisting algorithm and its performance is illustrated via numerical examples.}, subject = {Distributed power generation; Frequency control; Parameter estimation; Power plants; Power system control; Frequenzsignale; Massentr{\"a}gheit; Systemsteuerung; Transformation; Frequenzdynamik; Energieversorgung; Frequenzstabilit{\"a}t}, language = {en} }
