Die Tagesschau-App und die Notwendigkeit der Schaffung eines "Intermedienkollisionsrechts"

The article takes up the example of online news-services to describe the overall purpose of Germany\u27s public broadcasting corporation within the new networks of electronic media. It argues that the rise of the Internet is an evolutionary jump in the history of media. For this reason the traditional constitutional regime of guaranteeing pluralism in broadcasting can no longer be applied as a rationale and justification. Rather, a new constitutional type of conflict of law rules should be inaugurated to cope with the rising economic competition between public and private online news-services

Ship-scale CFD benchmark study of a pre-swirl duct on KVLCC2

Installing an energy saving device such as a pre-swirl duct (PSD) is a major investment for a ship owner and prior to an order a reliable prediction of the energy savings is required. Currently there is no standard for how such a prediction is to be carried out, possible alternatives are both model-scale tests in towing tanks with associated scaling procedures, as well as methods based on computational fluid dynamics (CFD). This paper summarizes a CFD benchmark study comparing industrial state-of-the-art ship-scale CFD predictions of the power reduction through installation of a PSD, where the objective was to both obtain an indication on the reliability in this kind of prediction and to gain insight into how the computational procedure affects the results. It is a blind study, the KVLCC2, which the PSD is mounted on, has never been built and hence there is no ship-scale data available. The 10 participants conducted in total 22 different predictions of the power reduction with respect to a baseline case without PSD. The predicted power reductions are both positive and negative, on average 0.4%, with a standard deviation of 1.6%-units, when not considering two predictions based on model-scale CFD and two outliers associated with large uncertainties in the results. Among the variations present in computational procedure, two were found to significantly influence the predictions. First, a geometrically resolved propeller model applying sliding mesh interfaces is in average predicting a higher power reduction with the PSD compared to simplified propeller models. The second factor with notable influence on the power reduction prediction is the wake field prediction, which, besides numerical configuration, is affected by how hull roughness is considered

Harold J. Berman (1918 ‐ 2007)

In the 20th century, a specifically normative integration of Western civilization collapsed – and in the 20th century all paradigms corresponding to this system lost their meaning. The symbols of a great Western (legal-) society regressed into nothing more than shallow and abstract nationalisms; visions of a just community were transformed into the law of nation-focused social engineers on both sides of the iron curtain. Expedience, practicability, and the reduction of law to an apparatus of technical tricks, replaced fundamental legal convictions. A world ends when its metaphor has died. These are the core theories in Harold J. Berman’s book Law and Revolution: The Formation of the Western Legal Tradition, which made him famous. Foi no século XX que uma particular integração normativa Ocidental entrou em colapso – e foi no século XX que todos os paradigmas correspondentes a esse sistema perderam seu significado. Os símbolos da grande sociedade (jurídico) Ocidental regrediram a nada mais que nacionalismos abstratos e superficiais; visões de uma comunidade justa foram transformadas por uma engenharia social em ambos os lados da cortina de ferro, em um direito focado no Estado Nacional. Eficiência, praticidade, e a redução do direito a um aparato de truques técnicos, substituíram convicções legais fundamentais. Um mundo acaba quando sua metáfora morre. Essas são as teorias centrais no livro Law and Revolution: The formation of Western Legal Tradition de Harold J. Berman (publicado em português pela editora Unisinos como Direito e Revolução: A formação da tradição jurídica Ocidental), que o tornou famoso
