Bildfolgenbasierte Gewinnung und Nutzung partikelindividueller Bewegungsinformation in der optischen Schüttgutsortierung
(2022)
Sensor-based sorting enables the separation of individual particles from a material stream. In this work, a novel sorting system using an area-scan camera is investigated. The use of high-speed cameras raises exciting ...
Praxis der Digitalen Signalverarbeitung
(2017)
The basics of digital signal processing are introduced with eight practical experiments. The experiments cover a wide range of different topics such as sensor fusion, vibration analysis, acoustics and image processing. The ...
Adding nonlinearity to an electromagnetic-magnonic quantum hybrid device
(2020)
In this book, hybrid systems based on yttrium-iron-garnet (YIG), three dimensional microwave cavity resonators, and superconducting transmon qubits, are investigated by continuous wave and pulsed microwave spectroscopy. ...
Power Generation by Resonant Self-Actuation
(2023)
Research into micro energy harvesting systems has been driven by the need for self-sustaining, stable power sources for interconnected wireless sensors. Waste heat, particularly at temperatures below 200 °C, presents a ...
Parameter- und Ordnungsidentifikation von fraktionalen Systemen mit einer Anwendung auf eine Lithium-Ionen-Batteriezelle
(2022)
Model-based methods are increasingly being used for a safe and efficient operation of battery cells. For modeling battery cells, fractional models which are characterized by non-integer derivative orders have become ...
Biegefestigkeit von Trägern aus kreissektorförmigen Lamellen
(2022)
Laminated Segment Timber (LST) consists of mutually glued trapezoidal lamellas made of Spruce. Due to the optimization of process parameters the wood yield can be increased to an average of 85 %. LST and layered LST are ...
Analyse und Modellbildung von PEM-Brennstoffzellen mittels elektrochemischer Impedanzspektroskopie
(2024)
This work presents a physically motivated model for predicting the current/voltage behavior of PEM fuel cells. Extensive impedance measurements and DRT analyses were used to identify and quantify all loss processes. The ...
Entwicklung einer Methode zum Einsatz von Reinforcement Learning für die dynamische Fertigungsdurchlaufsteuerung
(2023)
This work aims to develop a method that can reschedule the matrix production in the case of a disruption. For this purpose, different artificial intelligence methods are combined in a novel way. The developed method is ...
Untersuchung der Augensicherheit durch Multi-Pulsbestrahlung für LiDAR-Anwendungen
(2022)
LiDAR (Light detection and ranging) represents one of the key technologies for autonomous driving. For this reason, this work is concerned with the question of eye safety of the laser-based technology. For this purpose, ...
Modellierung und Optimierung der strömungstechnischen Vorgänge in Abweiseradsichtern
(2022)
Centrifugal classifiers are processing machines used in the gas-particle classification. The aim of this work is to reduce energy costs by improving the classification properties and reducing the pressure drop. In addition ...
Effizienzoptimierung mobilhydraulischer Load-Sensing-Systeme durch Reduzierung systembedingter Druckverluste am Beispiel eines Hydraulikbaggers
(2024)
In this thesis, a hydraulic circuit will be developed, which can reduce the partial load losses of hydraulic-mechanic load-sensing systems (LS). As reference application, the LS system of an hydraulic excavator will be ...
Perspectives on warm conveyor belts - sensitivities to ensemble configuration and the role for forecast error
(2023)
Warm conveyor belts (WCBs) are weather systems that substantially modulate the large-scale extratropical circulation. As they can amplify forecast errors and project them onto the Rossby wave pattern, they are of high ...
Der Spröd-duktil-Übergang in ultrafeinkörnigem Wolfram
(2023)
High brittle-ductile transition temperatures preclude the use of conventionally manufactured tungsten (W) as a structural material. Ultrafine grained (UFG) W materials, however, exhibit the brittle-ductile transition at ...
Dynamics of Rotors on Refrigerant-Lubricated Gas Foil Bearings
(2021)
The gas foil bearing (GFB) technology is a key factor for the transition to oil-free rotating machinery. Among numerous advantages, GFBs offer the unique ability to be lubricated with working fluids such as refrigerants. ...
Optical coherence tomography for characterization of nanocomposite materials
(2021)
Major challenges in nanoparticle and nanocomposite development are the control of particle size and shape, and to achieve uniform particle dispersion. In this book, the application of optical coherence tomography (OCT) for ...
Knowledge-Driven Harmonization of Sensor Observations: Exploiting Linked Open Data for IoT Data Streams
(2021)
The rise of the Internet of Things leads to an unprecedented number of continuous sensor observations that are available as IoT data streams. Harmonization of such observations is a labor-intensive task due to heterogeneity ...
Principles of Catastrophic Forgetting for Continual Semantic Segmentation in Automated Driving
