A numerical scheme for moment equations of kinetic theory, due to LeTallec & Perlat, is considered for the calculation of stationary heat transfer in the Grad 13 moment system and linearized extended thermodynamics of 14 moments. It is shown that the required distance of grid points must be considerably smaller than the mean free path. Thus, the kinetic scheme is useful only in the case of larg...

A design study of a 7 MeV/u C injector LINAC for a synchrotron for light-ion tumour therapy is presented. The injector consists of a 14.5 GHz ECR ion source, a LEBT line, a 216 MHz RFQ structure of 1.2 m length for acceleration from 6 keV/u to 300 keV/u and a subsequent 216 MHz IH drift tube LINAC of 4.0 m length for acceleration to 7 MeV/u. The IH structure consists of four drift tube sections...

The Grad-Shafranov (GS) reconstruction technique, a single-spacecraft based data analysis method for recovering approximately two-dimensional (2-D) magnetohydrostatic plasma/field structures in space, is improved to become a multi-spacecraft technique that produces a single field map by ingesting data from all four Cluster spacecraft into the calculation. The plasma pressure, required for the t...

We study restricted homomorphism dualities in the context of classes with bounded expansion. This presents a generalization of restricted dualities obtained earlier for bounded degree graphs and also for proper minor closed classes. This is related to distance coloring of graphs and to the “approximative version” of Hadwiger conjecture.

We all know that teachers teach and good learning relies signiicantly on good teaching. We also know that the major ingredients of good teaching are academic competency, pertinent course objectives, coherent syllabus, and integrated, objective-related assessment of student learning. More recently, the emphasis on active learning has revealed that actively engaging students in the process of lea...

In industrialisierten Branchen wie dem Automobilsektor manifestiert sich die Industrialisierung aus Herstellersicht unter anderem in einer zunehmenden unternehmensexternen Spezialisierung. Ziel des Beitrags ist es daher zu untersuchen, ob sich eine solche Industrialisierung auch in der relativ jungen SoftwareBranche beobachten lässt. Diese Untersuchung wurde für das Wertschöpfungssystem um die ...

Recent advances in vision tasks (e.g., segmentation) highly depend on the availability of large-scale real-world image annotations obtained by cumbersome human labors. Moreover, the perception performance often drops significantly for new scenarios, due to the poor generalization capability of models trained on limited and biased annotations. In this work, we resort to transfer knowledge from a...

Finite width photospheric sources are used to generate coronal potential magnetic field configurations. The prescription of a suitable distribution of the magnetic flux function within such regions allows to solve the Grad-Shafranov equation and, using the superposition principle, to obtain magnetic field configurations related to arbitrary combinations of photospheric sources and sinks. Follow...
