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 , ...

Methoden zur Beurteilung der statischen Brauchbarkeit von Tragwerken
(Institut für Baustatik und Baudynamik, Universität Stuttgart, 2020)
Fehler in der Tragwerksplanung können zu kinematischen (beweglichen) Tragwerken führen, die aus statischer Sicht unbrauchbar sind. Mit dem Ziel, den Statiker beim Auffinden und Beheben derartiger Fehler zu unterstützen, müssen spezielle Methoden entwickelt werden. Dieser Beitrag enthält einen Überblick über klassische und moderne Methoden. Dabei erfolgt eine Klassifizierung in indirekte, direkte, Ursachen-spezifische und akademische Methoden.

Utilizing Continuous Kernels for Processing Irregularly and Inconsistently Sampled Data With Position-Dependent Features
(2023-03-13)
Continuous Kernels have been a recent development in convolutional neural networks. Such kernels are used to process data sampled at different resolutions as well as irregularly and inconsistently sampled data. Convolutional neural networks have the property of translational invariance (e.g., features are detected regardless of their position in the measurement domain), which is unsuitable for certain types of data, where the position of detected features is relevant. However, the capabilities of continuous kernels ...

On the Challenges toward Realization of Functionally Graded Structures by Electron Beam Melting—Fe-Base Shape Memory Alloy and Stainless Steel
(ASTM International, 2020-09-22)
In the present study, an iron-manganese-aluminum-nickel (Fe-Mn-Al-Ni) shape memory alloy was processed on an austenitic steel (AISI 304) build platform by electron beam melting in order to study the feasibility of realizing functionally graded structures consisting of two different materials (i.e., a functional and a structural material). Compression specimens consisting of the processed shape memory alloy and the austenitic build platform in equal parts were investigated. The microstructure was analyzed in the ...

Effects of the Cellular Morphology on Fatigue Deformation Mechanisms of Physically Foamed Polycarbonate
(2023)
In this study, the tension–tension fatigue behavior of foam injection molded thermoplastic microcellular Polycarbonate (PC) is characterized. The variation in morphology is obtained by modifying the mold temperature, injection volume, injection flow rate, and blowing agent content (physical and chemical) in the polymer melt. The relationship between the wide range of morphological qualities and relevant fatigue properties is made explicit via a statistical correlation coefficient analyses. The analysis is made between ...

Microstructural and Mechanical Properties of AISI 4140 Steel Processed by Electron Beam Powder Bed Fusion Analyzed Using Miniature Samples
(ASTM International, 2022-02-26)
The present study reports on the identification of an adequate process window for electron beam powder bed fusion (E-PBF) of AISI 4140 steel. For characterization, only miniature samples were used. It is clearly revealed that, for comparison and evaluation of different conditions, the use of such small samples is absolutely sufficient, even under fatigue loading. The initial E-PBF as-built condition is compared with conventionally heat-treated conditions (i.e., normalized as well as quenched and tempered). Based on ...

Unionsrechtliche Maßnahmen zugunsten des beschleunigten Ausbaus von erneuerbaren Energien
(2023)
Bislang beschränken sich die Vorgaben der Richtlinie über erneuerbare Energien darauf, bestimmte Anteile erneuerbarer Energien am Energiemix vorzuschreiben. So sah Art. 3 im Jahr 2018 vor, den Anteil am Gesamtenergieverbrauch bis 2030 auf 32 % zu steigern. Art. 16 verlangt bislang vor allem die Einrichtung von Anlaufstellen, Regelungstransparenz und eine Verfahrensdauer von zwei, ausnahmsweise drei Jahren. Inhaltliche Vorgaben für Genehmigungsverfahren fehlen dagegen bislang noch.
In jüngster Zeit unternimmt die ...
