A novel evaluation framework for energy losses in low voltage distribution grids
(kassel university press, 2020)
Decentralization of energy generation in power distribution systems is recognized as an important development strategy to incorporate more small-scale renewable sources, reduce greenhouse gas emissions and increase energy efficiency. Beside integrating more decentralized generators into existing systems, an efficient system operation is equally important to achieve an overall sustainable energy system. In order to keep track of upcoming changes regarding system efficiency, an accurate determination of energy losses ...

Cooperative intention detection using machine learning. Advanced cyclist protection in the context of automated driving
(kassel university press, 2021)
Cyclists will play an essential role in future traffic. It is crucial to detect cyclists and predict their intentions to avoid accidents and achieve a highly efficient traffic flow. Vehicles equipped with sensors, data processing systems, and communication abilities acquire and maintain a local model of their surrounding traffic environment, e.g., crossing cyclists. Cooperating and interacting vehicles, roadside units, and cyclists equipped with smart devices and other body-worn sensors exchange information.They form ...

Bausteine einer wertschätzenden Schulkultur
(kassel university press, 2020)
Die vorliegende Arbeit setzt sich am Beispiel der Georg-Christoph-Lichtenberg-Gesamtschule Göttingen tiefergehend mit dem Begriff der „Wertschätzung“ und der möglichen Wirkungsweise eines wertschätzenden Verhaltens auseinander. Ziel dieser Arbeit ist es gewesen, die wichtigsten Bausteine einer wertschätzenden Schulkultur herauszuarbeiten und zu definieren, sie für interessierte Pädagoginnen und Pädagogen zugänglicher zu machen und konkrete Handlungsanweisungen für ein wertschätzendes Miteinander im schulischen Kontext ...

Multi-Year Time-Series-Based power system planning with hybrid optimization and supervised learning methods
(kassel university press, 2021)
The increasing share of renewable energy sources (RES) in the power system necessitates new planning methods for power systems systems. On the one hand, flexible operational measures must be included in planning. On the other hand, conventional measures have to be considered. An integrated optimization of both measures is needed. This integrated optimization requires time series simulations of the power system in comparison to traditional worst case planning approaches.
The high voltage (HV) level has the highest ...

Optimizing Control of Distributed Cyber-Physical Systems
(kassel university press, 2021)
In this thesis, a set of modeling and control strategies are proposed for Cyber-physical systems (CPS), which aim at ensuring a safe, reliable, and highly performant operation of each local subsystem contained in the CPS. Modeling of CPS is challenging since not only must the tight interconnection of continuous and discrete dynamics of local subsystems be exactly represented, but so must also the interleaving structure between different subsystems. Optimal control of CPS, accordingly, should take into account not ...

Untersuchungen zum Einsatz leistungselektronischer Spannungsregler in Niederspannungsverteilnetzen mit hohem Anteil dezentraler Erzeugungsanlagen
(kassel university press, 2020)
Die steigende Stromerzeugung aus erneuerbaren Energien stellt das elektrische Energieversorgungssystem vor neue Herausforderungen. Für Verteilnetze mit zunehmender Durchdringung mit dezentralen Erzeugungsanlagen sind besonders Maßnahmen zur Spannungshaltung relevant. Systemkonzepte zur aktiven Spannungsregelung stellen hierbei Alternativen zu konventionellen Netzverstärkungsmaßnahmen dar. In dieser Arbeit wird daher der Einsatz von leistungselektronischen Spannungsreglern in aktiven Niederspannungsverteilnetzen ...

Design and Modeling of Semiconductor Terahertz and Infrared Sensing Structures for Protein Characterization
(kassel university press, 2020)
The subject area of biological sensing becomes progressively more attractive for medicine and fundamental biological research. In these fields, the investigation of characteristic fingerprints of membrane proteins is important, as they are responsible for the communication and activity of biological cells. Moreover, these complex structures are essential for the transport of various substances into the cell and are suitable as a drug target. These kinds of proteins provide vibrational resonances between 200GHz and 2 ...

Entwicklung eines Verkehrssicherheitsprogramms für Radfahrende zwischen 11 und 14 Jahren mit dem Fokus auf metakognitiven Fähigkeiten
(kassel university press, 2022)
Im Jahr 2019 verunglückten ca. 29.000 Kinder (bis 15 Jahre) im Straßenverkehr in Deutschland (Statistisches Bundesamt 2020). Die Jahrgänge mit den meisten Unfallopfern sind dabei die 11- bis 14-Jährigen, von denen wiederum etwa die Hälfte (ca. 6.000 Kinder) mit dem Fahrrad verunglückte. Die Zahl der verunglückten Radfahrer steigt nach dem Wechsel von der Grundschule auf die weiterführende Schule stark an. Dies ist auf ein geändertes Fahrverhalten nach dem Schulwechsel im Vergleich zur Grundschulzeit zurückzuführen. ...

Grazing effects and resource use by large herbivores in arid and semi-arid rangelands
(kassel university press, 2022)
The present study resulted in the development and application of a high-resolution, spatially-explicit agent-based model of ruminant livestock herds in semi-arid rangelands. The model provides a useful tool to assess potential strategies and effects of locally adapted herd and rangeland utilization on sustained food security and household economy of livestock keepers in tropical and sub-tropical drylands. The findings of this study might furthermore spark interest in the further application of object-based, dynamic ...

Capital, Labour & the State in the Gulf
(kassel university press, 2022)
To date, issues of international mobility of capital, people and information continue to be a central part of debates within a large array of academic disciplines. One often and widely made observation is that there is a fundamental asymmetry between the international mobility of capital and labour in favour of capital. In this context, many scholars contend that the international mobility of capital and/or its promotion by states stands in sharp contrast to the restrictions on the international mobility of labour. ...
