Organic Food System cases around the world
(kassel university press, 2021)
The global food system continues to be threatened by climate change, environmental degradation, food insecurity, and hidden hunger. Consequently, both ecosystem- and human health issues will continue or worsen if no sustainable strategies are adopted. In the search for food system transformation, organic is a promising approach to achieve sustainable food systems. From a food systems perspective organic actors share a value-based ethical vision and follow codifi ed principles that lead to sustainable outcomes. Organic ...

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 ...

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 ...

Handwerk @ Home
(kassel university press, 2021)
Die Publikation "Grown in Germany' dokumentiert die Kooperation zwischen der Studienwerkstatt Textil in der Kunsthochschule Kassel und dem Fachbereich Architektur, Stadtplanung, Landschaftsplanung der Universität Kassel im Sommersemester 2020. Ziel der Veranstaltung war die Annäherung an das funktionale und ästhetische Potential des Webens als Handwerk und das Sammeln eines Fundus an für die Technologie des Webens geeigneten Rohstoffen, die in Deutschland vorkommen, wachsen oder anfallen. Die Studierenden setzten ...

Reactive power grid adequacy studies for distribution grids with high distributed generation
(kassel university press, 2020)
The study aims to develop practicable grid planning procedures for an advanced reactive power management at the transmission-distribution (T-D) interface by making use of controllable reactive power sources at the distribution level, like distributed energy resources (DER) and reactive power compensators. In Germany, also the high voltage level is mainly considered as a part of distribution grid, and the T-D interface is determined at the interface between high voltage and extra high voltage level. A predefined ...

Thermische Prozessierung & funktionale Charakterisierung von Fe-Mn-Al-Ni-basierten Formgedächtnislegierungen
(kassel university press, 2020)
Im Rahmen der vorliegenden Arbeit werden die thermische Prozessierung sowie das funktionale Verhalten von Fe-Mn-Al-Ni-basierten Formgedächtnislegierungen erforscht. Dabei wird zunächst die Mikrostruktur im Hinblick auf Korngröße, Korngrenzen und Ausscheidungsteilchen so modifiziert, dass die Legierung in der Lage ist gute pseudoelastische Eigenschaften aufzuweisen. Anschließend wird das funktionale Verhalten im Hinblick auf den Einfluss von Kornorientierungen und Korngrenzen sowie auf die mehrmalige zyklische ...

Advanced theory of optical wave propagation and interferometric sensors for topography measurement
(kassel university press, 2020)
This manuscript provides a compendium for the application of the nonuniform wave model to standard problems of two beam interference and addresses common educational issues associated with wave propagation at attenuating interfaces. It also reports scientific advances in interferometric applications focusing on an interferometric point sensor with optical path length modulation and an areal measuring RGB-interferometer for fast topography measurements in the sub millisecond regime.

Architekturen und Verfahren für modulare Pilotsysteme und Erweiterungen von Netzleitstellen
(kassel university press, 2021)
Durch den erhöhten Anteil von dezentralen Erzeugern wie Photovoltaik- und Windkraftanlagen sind neue Ansätze für eine bessere Integration in das Stromnetz erforderlich. Einen Ansatz stellen Softwarelösungen dar. Bisher werden Stromnetze von Leitwarten und dessen Software gesteuert und überwacht. Eine Leitwarten-Software ist aber oft ein in sich geschlossenes System, das nur von deren Anbieter gewartet und um neue Funktionen erweitert werden kann. Es können aber auch andere Hersteller neue Lösungen anbieten, die ...

On the Detection and Selection of Informative Subsequences from Large Historical Data Records for Linear System Identification
(kassel university press, 2022)
Performing experiments for system identification of continuously operated plants might be restricted as it can impact negatively normal production or cause safety issues. In such cases, using historical logged data for system identification can become an attractive alternative instead of carrying out new experiments.
However, since such plants work normally at operating points that are seldom changed, parameter estimation methods with logged data can suffer numerical problems. Methods to locate and select informative ...
