On the Impact of Non-Optimal Parameters in Additive Manufacturing - From Microstructure to Mechanical Properties
(kassel university press, 2024)
The additive manufacturing with its layerwise built-up comprises a variety of tempting properties such as an unprecedented freedom of design and tailorable mechanical properties. Amongst others, the laser-based powder bed fusion of metals (PBF-LB/M) as one representative additive manufacturing process permits the production of highly complex parts requiring a minimum of post-processing effort. As the additive manufacturing techniques are still rather new, there are still several open questions concerning the ...

Design, Control, and Harmonic Compensation for Stand-Alone and Grid-Connected Voltage-Source Converters: Simulation and Experimental Validations
(kassel university press, 2024)
Voltage source converters (VSCs), among other power converters, play a crucial role in supplying power to both local loads and the grid at the PCC. During standalone operation, VSCs ensure stable power for loads by regulating the output voltage. In grid-connected mode, the regulation shifts to controlling output current, such as converter side current (CSC) or grid side current (GSC), to inject sinusoidal current into the electrical grid. The nonlinear characteristics of the loads connected to the power converters ...

Improving the Security-Constrained Operative Planning of Flexibilities in Distribution Grids Using Artificial Intelligence and High-Performance Grid Calculation
(kassel university press, 2024)
The penetration from renewable distributed energy resources (DERs) such as wind and solar massively increases the risk of grid congestions on transmission lines/transformers and voltage violations. To guarantee grid security, the operators must perform grid congestion management (GCM), e.g., with active power curtailment from DERs in the operative planning and real-time phases. Compared to the real-time GCM, for grid operative
planning, grid congestions must be identified through forecasting-based grid simulations. ...

Theologie als Lehramtsstudium
(kassel university press, 2023)
Das Lehramtsstudium Theologie besitzt eine Qualität eigener Art. Anders als bei Studienabschlüssen, die sich ausschließlich auf die Theologie richten, liegt die Besonderheit des Lehramtsstudiums in der Verzahnung der Theologie mit anderen Studienfächern. Diese Verbindung führt über die bloße Addition unterschiedlicher Studieninhalte zu einem Mehrwert, der aus der Auseinandersetzung mit den anderen Fachkulturen resultiert. Lehramtsstudierende der Theologie vollziehen im Laufe ihrer Studienzeit eine anspruchsvolle ...

Handlungsbroschüre. Ko-Kreative Entwicklung von Lernmaterialien im Arbeitsprozess in der Fertigungsindustrie – Eine anwenderzentrierte Betrachtung
(kassel university press, 2022)
Digitale Lernsysteme sind heute viel mehr als reine Wissensdatenbanken, in welchen Mitarbeitende zentral abgelegte Wissensbausteine abrufen können. Mithin geht es um die Entwicklung solcher Wissensbausteine durch Mitarbeitende als eine zentrale Herausforderung bei der Gestaltung von digitalen Lernsystemen. Insbesondere deshalb, da bestehende Lernmaterialien oftmals nicht den Erfordernissen eines arbeitsprozessintegrierten Lernansatzes folgen. Dies liegt daran, dass die Lernmaterialien von Mitarbeitern erstellt werden, ...

Ultra-High Performance Concrete and High Performance Building Materials for Sustainability Construction
(kassel university press, 2024)
Sustainable construction, with the overarching goal of reducing the environmental footprint of everything we build is becoming increasingly important and urgent in the light of the climate change the world is facing. The use of innovative and sustainable building materials, especially concrete as the worldwide most commonly used building material, offers a great opportunity to significantly reduce climate-relevant emissions in the construction sector. Due to their performance and reliable durability, the use of ...
