Optimizing drying processes for agricultural products utilising non-invasive measurement and adaptive control systems
(2021)
With increasing population and global warming, the need for functional yet nutritional food combined with energy efficient processes has risen significantly. The new “Industry 4.0” revolution acknowledging this need aims to develop and improve processes that are affordable as well as sustainable. For a process like drying this means a shift towards smart or intelligent drying systems using a multidisciplinary approach. This encompasses the use of advanced computational algorithms and control systems integrated with ...

Development of feedback control for energy policy design to guarantee sustainable solar and wind power investment growth
(2021)
Energy transition in the power sector is one of the main pathways to achieving the climate targets. In order to stimulate renewable power development, regulatory policies play a vital role. However, these policies have so far attained only partial results or unexpected consequences due to the unsuitable designs. Therefore, the study addresses the question, “How do regulatory policies have to be designed in order to create a favorable environment for renewable power development?”
This work proposes to use feedback ...

Fine-scale grassland monitoring using unmanned aerial vehicle borne remote sensing
(2020-04)
RS is widely employed as a non-destructive methodology to monitor grasslands. Usage of UAV as the RS platform benefits to provide high spatial (fine-grain) and temporal resolution, unclouded data over small grassland extent. Therefore, this thesis evaluated the applications of UAV-borne RS for fine-scale grassland monitoring along with practical farm condition. Grass biomass estimation, predicting forage quality of grass and mapping invasive lupine in grasslands are considered as applications of UAVborne RS.

Entwicklung einer selbstjustierenden Formgebungsstruktur zur Herstellung formspezifischer 3D-Partikel basierend auf Nanoimprint-Technologie
(2020-11)
Ausgehend vom Soft-Nanoimprint-Verfahren wurde im Rahmen dieser Arbeit die Self-Aligned Molding Technology (SAMT) entwickelt. Die SAMT-Prägetechnologie ermöglicht eine wesentliche Reduzierung des Justieraufwands zur Herstellung echter 3D-Strukturen. Das Konzept basiert auf einem ‚Waffeleisen‘-Prinzip in Mikrometergröße und erlaubt in einem einstufigen Prägeprozess die Erzeugung komplexer 3D-Strukturen und -Partikel. Die SAMT Prägeform wurde in Form von 35 µm breiten V-Gräben im elastischen Polydimethylsiloxan (PDMS) ...
