Die Austro Moderne
(2023-01-10)
Die Länder Zentraleuropas lassen sich nicht einfach als Nachholer der westlichen Modernisierung begreifen. Der Beitrag zeigt vielmehr auf, wie die technischen Entwicklungen in den Autofabriken Lohner in Wien und Austro-Daimler in Wiener Neustadt vor sich gingen und der leichte und leistungsstarke Benzinmotor den Flugzeugbau (die Taube von Etrich) und Luftschiffbau vorantrieb. Im Flugzeugbau war Österreich um 1910 führend. Das kreative Milieu in Wien wird daran deutlich, dass die Hauptverwaltung der Lohnerwerke bloß ...

Minerva-Gentner Symposium: Burchard of Mount Sion’s Descriptio Terrae Sanctae
(2023-03-09)
The Minerva-Gentner Symposium on Burchard of Mount Sion’s Descriptio Terrae Sanctae, organized by Ingrid Baumgärtner and Jonathan Rubin, was held at Bar-Ilan University in Ramat Gan, Israel, from 28 November to 1 December 2022. In the workshop, German, Israeli, Italian and British scholars discussed the challenges – on the level of content, textual philology and technology – of publishing this work in print and digital form. The focus of the discussion was on questions relating to the new edition of the Descriptio , ...

Effect of market-driven minigrids on the frequency stabilization process of isolated middle-sized power grids
(2006-11-22)
Neueste Entwicklungen in Technologien für dezentrale Energieversorgungsstrukturen, erneuerbare Energien, Großhandelsenergiemarkt, Mini- und Mikronetze, verteilte Intelligenz, sowie Informations- und Datenübertragungstechnologien werden die zukünftige Energiewelt maßgeblich bestimmen. Die derzeitigen Forschungsbemühungen zur Vernutzung aller dieser Technologien bilden die Voraussetzungen für ein zukünftiges, intelligentes Stromnetz. Dieses neue Konzept gründet sich auf die folgenden Säulen: Die Versorgung erfolgt durch ...

Trucking in the Eastern Bloc
(2023-03-10)
This article explores the tensions during the Cold War between the need to have infrastructure to enable truck transport in the countries of the Eastern Bloc. Using “shortage economy” as the theoretical framework to analyse the Eastern bloc the article shows restrictions the shortage economy imposed on investments in infrastructure. The Western management started in the 1980s to let the enterprises’ transports to be carried out by external truck transport service providers – a policy which is known as “outsourcing”. ...

Quenching of High Entropy Alloys after Annealing
(2020)
The effect of cooling rate after annealing at 900 °C on the microstructure and hardness of high entropy alloys was investigated using two typical samples with the chemical composition of Co₁₆Cr₁₄.₅Fe₂₉Mn₁₁.₅Ni₂₉ and Co₁₁.₅Cr₇Fe₂₇Mn₂₇Ni₂₇(Nb₀.₀₈C₀.₅) (at%). The microstructural characterisation and hardness measurements were carried out by optical microscopy, scanning electron microscopy, wavelength-dispersive X-ray spectroscopy, electron back scattered diffraction, X-ray diffraction technique and Vickers hardness ...

Finding Spaces for Urban Food Production – Matching Spatial and Stakeholder Analysis with Urban Agriculture Approaches in the Urban Renewal Area of Dortmund-Hörde, Germany
(Department of Organic Food Quality and Food Culture at the University of Kassel, Germany and Federation of German Scientists (VDW), 2015-05-20)
Using the case of an economically declined neighbourhood in the post-industrial German Ruhr Area (sometimes characterized as Germany’s “Rust Belt”), we analyse, describe and conclude how urban agriculture can be used as a catalyst to stimulate and support urban renewal and regeneration, especially from a socio-cultural perspective. Using the methodological framework of participatory action research, and linking bottom-up and top-down planning approaches, a project path was developed to include the population affected ...

On the reliability of residual stress measurements in unidirectional carbon fibre reinforced epoxy composites
(2021-03-03)
The present work introduces a novel methodology to analyse non-uniform residual stresses in composite materials. For robust determination of stresses in complex structures made of different layers, it is first necessary to prove that residual stress analysis in a single layer structure can reliably be accomplished. In present work a unidirectional carbon fibre reinforced epoxy is investigated. For residual stress determination, the integral incremental hole drilling method is used. It is revealed that the standard ...
Working paper
Taylor and Taylorism
(2023-04-20)
Beyond the perspectives of labour science and industrial sociology, in which extensive deepening of the division of labour can be crystallized as an element of consensus under Taylorism, the concept of Taylorism found its way into general intellectual history. In 1954, the German-American management expert Drucker ranked scientific management among the most important contributions of the USA to Western culture. The dissemination of the concept of Taylorism in Western culture outlined here points to a high rank of ...

Abschlussergebnisbericht - KMU-Wissenstransferlabor „Digitale Fabrik“
(2023-04)
Der digitale Wandel stellt aufgrund der hohen Gestaltungskomplexität insbesondere kleine und mittlere Unternehmen (KMU) immer noch vor große Herausforderungen. Reifegradmodelle und Roadmaps bieten Möglichkeiten, diese Komplexität beherrschbar zu machen. Vor diesem Hintergrund hat das Fachgebiet Produktionsorganisation und Fabrikplanung an der Universität Kassel im Rahmen des Forschungsprojektes Wissenstransferlabor „Digitale Fabrik“ (Wislab) ein KMU-spezifisches Reifegradmodell, einen zugehörigen Erhebungsleitfaden ...

Comparative investigation of two-dimensional imaging methods and X-ray tomography in the characterization of microstructure
(2017-10-02)
The microstructural features of three different materials have been quantified by means of 2D image analysis and X-ray micro-computer tomography (CT) and the results were compared to determine the reliability of the 2D analysis in the material characterization. The 3D quantification of shrinkage pores and Fe-rich inclusions of an Al-Si-Cu alloy by X-ray tomography was compared with the statistical analysis of the 2D metallographic pictures and a significant difference in the results was found due to the complex ...
