Beitrag zur Entwicklung von Konstantflusspumpen für Frischbeton unter genauerer Betrachtung der Dickstoffventile
(2021)
On almost every construction site, mobile fresh-concrete pumps of different designs can be found, all of which have an interruptions in delivery. In this work, a fresh-concrete constant-flow pump is developed and simulated. ...
Abbildende Ellipsometrie mit Lichtwegumkehrung für die optische Charakterisierung von gekrümmten Oberflächen
(2023)
Ellipsometry is a measuring method for surface characterization and thin-film measurement of flat surfaces using polarized light. However, a new measuring principle based on return-path ellipsometry and retroreflection ...
Wirksamkeit der Taktplanung aus Perspektive des Bauherrn am Beispiel von Produktionsimmobilien in der Automobilindustrie
(2022)
This work analyses the time effect that occurs due to the use of takt planning and takt control during the construction process from the perspective of the client. At first the historical courses of takt planning and takt ...
New Type of sub-THz Oscillator and Amplifier Systems Based on Helical-Type Gyro-TWTs
(2023)
This work presents the development of a new sub-THz source for the generation of trains of coherent high-power ultra-short pulses at 263 GHz via passive mode-locking of two coupled helical gyro-TWTs. For the first time, ...
Self-learning Anomaly Detection in Industrial Production
(2023)
Configuring an anomaly-based Network Intrusion Detection System for cybersecurity of an industrial system in the absence of information on networking infrastructure and programmed deterministic industrial process is ...
Ein Verfahren zur lexikographischen modellprädiktiven Regelung mit der Anwendung auf eine permanenterregte Synchronmaschine
(2022)
In classical approaches for the torque control of Permanent Magnet Synchronous Machines the torque references are converted into current references by static lookup tables which consider power losses. This procedure is ...
Active Vision for Scene Understanding
(2021)
Visual perception is one of the most important sources of information for both humans and robots. A particular challenge is the acquisition and interpretation of complex unstructured scenes. This work contributes to active ...
Spannungseinprägende aktive Filter zur Kompensation der Stromverzerrungen von Netzstromrichtern
(2023)
In this thesis, the use of voltage-source active filters for harmonic mitigation of grid-connected power converters is proposed. Based on a modeling of this novel converter configuration, an operating strategy is derived ...
Der Quasi-n-Level Betrieb des Flying Capacitor Umrichters für Mittelspannungsanwendungen
(2024)
The quasi-n-level operation of the flying capacitor converter (FCCs) is an optimized operation mode of a multilevel converter. The quasi-n-level operation of a multilevel converter was presented with an analysis of its ...
