Diagenetic controls on fluid flow and mechanical properties in Rotliegend reservoir sandstones
(2021)
Reservoir quality of Rotliegend sandstones is mainly controlled by their permeability, and porosity, and their mechanical properties. Thus, diagenetic porosity-reducing processes need to be understood to evaluate reservoir ...
Technologische Beschreibung und physiologische Bewertung eines hochaufgelösten Laserscanner- Scheinwerfersystems
(2023)
The approach of a laser scanning headlamp for adaptive light functions includes six laser sources which are deviated on a micro mirror. The oscillation of that mirror generates an extended light distribution on a white ...
Frequenzkamm-basiertes breitbandiges MIMO-OFDM-Radar
(2022)
In recent years, OFDM has become more and more important for radar applications. A disadvantage, however, is the need for high sampling rates, which is exactly the starting point of the frequency comb OFDM radar scheme. ...
Multisensorielle Navigation und Kartierung in schwierigen Bedingungen
(2023)
Robust navigation as well as mapping of the environment are critical for autonomous aerial vehicles. This is especially challenging in poor visual conditions or degraded GNSS. Therefore, this thesis proposes multi-sensor ...
Detektion und Klassifizierung unterschiedlicher Bedeckungen auf Abschlussscheiben von LiDAR-Sensoren
(2022)
By providing a high resolution at high distances in a broad field of view, LiDAR sensors are a key element in automated driving cars. However, in harsh environmental conditions, particles from rain or dust attach on the ...
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 ...
Motion Planning for Autonomous Vehicles in Partially Observable Environments
(2023)
This work develops a motion planner that compensates the deficiencies from perception modules by exploiting the reaction capabilities of a vehicle. The work analyzes present uncertainties and defines driving objectives ...
Theoretische und praktische Entwicklung einer aufgeklebten CFK Stahlbetonverstärkung unter Berücksichtigung der vollständigen Kompatibilität zum Betonstahl
(2021)
Components made of reinforced or pre-stressed concrete often show deficits or damage that lead to the necessity of a strengthening action. In this case, strengthening and repair with externally bonded (EB) CFRP strips is ...
