We give a summary of the state-of-the-art of heterostructure RF-device simulators for industrial application based on III-V compound semiconductors and compare critical modeling issues. Results from two-dimensional hydrodynamic simulations of High Electron Mobility Transistors (HEMTs) and Heterojunction Bipolar Transistors (HBTs) with MINIMOS-NT are presented. Simulation examples are chosen to ...

We present the derivation of the hydrodynamic limit under Eulerian scaling for a general class of one-dimensional interacting particle systems with two or more conservation laws. Following Yau’s relative entropy method it turns out that in case of more than one conservation laws, in order that the system exhibit hydrodynamic behaviour, some particular identities reminiscent of Onsager’s recipro...

Hydrodynamic modeling of rivers with flood simulation requires an accurate description the riverbed and inundation morphology. Depending on a geodetic survey method data collected, digital elevation models different accuracy can be created. This paper describes methodology for creating hybrid model intended hydraulic calculations, analysis, results systematization interpretation. The case study...

Context. The progenitor mass of type IIP supernova can be determined from either hydrodynamic modeling of the event or pre-explosion observations. Aims. To compare these approaches, we determine parameters of the sub-luminous supernova 2005cs and estimate its progenitor mass. Methods. We compute the hydrodynamic models of the supernova to describe its light curves and expansion velocity data. R...
