Partizipative Infrastrukturentwicklung in nordhessischen Dorfgemeinschaften
(kassel university press, 2022)
A functioning rural community, diverse club activities or special local traditions. These are familiar to most inhabitants of the rural area. However, these aspects represent quality of rural life only for some, while less appreciated by others. The latter consider infrastructure, which are meant to be added value, a waste of communal funds.
Debating voluntary services and infrastructure of rural areas is a central topic of this dissertation entitled “Participatory development of infrastructure to promote village ...

Entwicklung eines Algorithmus zur luftqualitätsgeführten Volumenstromregelung bei Dunstabzugshauben
(kassel university press, 2018)
Die vorliegende Arbeit analysiert im Rahmen einer systematischen Untersuchung die luftqualitätsgeführte Volumenstromregelung bei Dunstabzugshauben mit VOC-Sensoren.Zunächst werden unterschiedliche VOC-Sensoren ausgewählt und durch messtechnische Untersuchungen charakterisiert. Danach erfolgt die Aufstellung eines mathematischen Modells zur Bilanzierung der Massenströme bei Koch- und Garprozessen. Die anschließend durchgeführte versuchstechnische Auswertung der Lüftungseffektivität untersucht deren Einfluss auf die ...

Selbstreflexion zwischen psychologischer Theorie und schulischer Praxis
(kassel university press, 2023)
Der vielfach betonten Notwendigkeit für Lehrkräfte sich im professionellen Handeln stetig zu reflektieren und der Forderung diese Fähigkeit bereits in der Lehramtsausbildung anzubahnen, steht die mangelnde Klarheit darüber gegenüber, wie genau sich Selbstreflexion praktisch vollzieht, was sie auslöst und wie sie gefördert werden kann. Die vorliegende Dissertation arbeitet die aktuelle theoretische Konzeptualisierung der Selbstreflexion aus psychologischer Perspektive auf und versucht die Rolle emotionalen Erlebens ...

Mixed-mode cohesive cracks and complex potentials of linear elastic fracture mechanics: new theoretical aspects and numerical applications
(kassel university press, 2023)
The J-integral is a powerful tool to determine crack tip loading, where the J-integral vector also allows for the quantification of crack deflection applying the J-integral vector criterion. Although originally formulated for sharp cracks with a crack tip singularity, the J-integral vector can also be derived for cracks with cohesive zones. The relation and proof of equivalency of the first coordinate of the vector and the crack tip opening displacement, typically associated with the cohesive zone model, has been ...

Comparison and investigation of various topography sensors using a multisensor measuring system
(kassel university press, 2022)
With increasing miniaturization and rising demands on the manufacturing accuracy of surface structures in the micro- and nanometer range, the requirements for measurement technology to ensure manufacturing quality also increase. Various tactile and optical measurement techniques are available for this purpose. Since these differ in their transfer behavior, the systematic deviations occurring in height values measured on critical surface structures also differ. The identification of such systematic measurement deviations ...

Application-Oriented Reactive Power Management in German Distribution Systems Using Distributed Energy Resources
(kassel university press, 2022)
Nowadays, according to the technical connection guidelines in Germany (VDE-AR-N) for distributed energy resources (DERs), a relevant reactive power provision potential can be provided from the existing DERs in the German distribution grids. The German distribution system operators, therefore, could make use of the existing reactive power potential for providing different kinds of ancillary services. In this thesis, an application-oriented reactive power management concept is proposed and discussed. The proposed ...

A Hybrid Flow-based Intrusion Detection System Incorporating Uncertainty
(kassel university press, 2022)
The advances of today’s cyberattacks threatening network infrastructures are both versatile and alarming. This requires thoroughly planned security solutions to spot malicious behavior in those networks. Systems serving this duty are intrusion detectors commonly relying on deep packet inspection, which come up with high resource consumption because network traffic is observed at a very fine granularity. With increasing link speeds of current and future networks, this situation is becoming a serious affair for operational ...

Interdependencies in infrastructure investment decisions in multi-energy systems
(kassel university press, 2022)
In the EU, the heating and cooling sector accounts for 50% of final energy demand. The EU's current climate protection goals demand a decarbonization of this sector by 80-95% by 2050. To reach this goal, one major scenario predicts the predominant use of gas-based systems supplied with CO₂ neutral gases to mitigate CO₂ emissions. A second scenario foresees a strong electrification of heating systems through heat pumps powered by renewable electricity.
Both scenarios have a strong impact on electricity and even more ...

Organic Computing
(kassel university press, 2022)
The Organic Computing Doctoral Dissertation Colloquium (OC-DDC) series is part of the Organic Computing (OC) initiative which is steered by a Special Interest Group of the German Society of Computer Science (Gesellschaft für Informatik e.V.). It provides an environment for PhD students who have their research focus within the broader OC community to discuss their PhD project and current trends in the corresponding research areas, including, for instance, research in the context of Autonomic Computing, Self-adaptive ...
