Dynamical Modeling and Control of Multiphase Heat Transport Systems Based on Loop Heat Pipes
(2022)
Effective heat transport systems in aerospace are based on multiphase loop heat pipes (LHPs). For a precise thermal control of the electronics, electrical heaters are additionally used to control the operating temperature ...
Transactive Control of Coupled Electric Power and District Heating Networks
(2023)
The design of approaches for future market-based energy network operation faces the technical challenge of needing to coordinate a vast number of network participants spatially and temporally, in order to balance energy ...
Energy-efficient, scalable and modular industrial microwave applicator for high temperature alkaline hydrolysis of PET
(2023)
Microwave-assisted alkaline hydrolysis of PET can be 20 times faster and at lower temperatures. This work presents a novel industrial microwave applicator at 2.45 GHz with homogeneous distribution to support this reaction, ...
Entwicklung eines Entscheidungsunterstützungssystems (EUS) für die Auswahl von Verfahren zur Instandsetzung von Einkammerschleusen für die Schifffahrt unter laufendem Betrieb
(2023)
A two-stage decision support system (DSS) was developed for the selection of maintenance procedures for single-chamber locks while they are in operation. The Choosing by Advantages Decision Making System (CBA) tabular ...
Kleinskalige Charakterisierung der Fest-Flüssig-Trennung und Betrachtung des Scherbruchs von Proteinkristallen
(2022)
Proteins are macromolecules composed of amino acids that are essential for a large number of biological metabolic processes. Proteins are also used in technical applications, for example to catalyze reactions. The objective ...
Convective precipitation simulated with ICON over heterogeneous surfaces in dependence on model and land-surface resolution
(2021)
The impact of land-surface properties like vegetation, soil type, soil moisture, and the orography on the atmosphere is manifold. These features determine the evolution of the atmospheric boundary layer, convective conditions, ...
Roboter für Assistenzfunktionen
(2024)
The performance and flexibility of robot technologies make it possible to bring robots to everyday life. This creates many challenges: safety, legal regulations, reliability, reusability, and business models must be ...

Innovative tools and design strategies
(2023)
The research deals with a question about Architecture and its design strategies, combining historical information and digital tools. Design strategies are historically defined, they rely on geometry, context, building ...
Simulation of the thermoforming process of UD fiber-reinforced thermoplastic tape laminates
(2021)
In this work, initially, the requirements on a simulation model of the non-isothermal stamp forming process of unidirectional fiber-reinforced, and thermoplastic tape laminates are investigated experimentally. On this ...
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 ...
Numerical prediction of curing and process-induced distortion of composite structures
(2021)
Fiber-reinforced materials offer a huge potential for lightweight design of load-bearing structures. However, high-volume production of such parts is still a challenge in terms of cost efficiency and competitiveness. ...
On the Electro-Chemo-Mechanical Coupling in Solid State Batteries and its Impact on Morphological Interface Stability
(2021)
Solid state batteries with a lithium metal electrode are considered the next generation of high energy battery technology. Unfortunately, lithium metal is prone to harmful protrusion or dendrite growth which causes dangerous ...
Entwicklung von Modellen zur speichergestützten Versorgung mit regenerativen Energien in Inselnetzen
(2022)
The proposed method for the configuration of renewably powered energy supply systems as isolated grids backed by energy storage technology and based on statistical models shows the economic viability of such a system. The ...
Fiber Orientation Tensors and Mean Field Homogenization
(2023)
Effective mechanical properties of fiber-reinforced composites strongly depend on the microstructure, including the fibers' orientation. Studying this dependency, we identify the variety of fiber orientation tensors up to ...
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 ...
Compaction and cementation controls on reservoir quality in Buntsandstein red beds
(2022)
Reservoir quality in fluvial siliciclastic rocks is variable. Permeability is influenced by micron-scale grain coatings or bedding style on the m-/km-scale. Outcrops allow the analysis of depositional environments and ...
