Creating steep density profile with a separatrix
Themesoscopic properties of a plasma in a cylindrical magnetic field are investigated from the view point of test-particle dynamics. When the system has enough time and spatial symmetries, a Hamiltonian of a test particle is completely integrable and can be reduced to a single degree of freedomHamiltonian for each initial state. The reduced Hamiltonian sometimes has an unstable fixed point (sad...
متن کاملTransparency of overdense plasma with V shape density profile
In this study, we investigate the transparency of an overdense inhomogeneous plasma slab. This anomalous transmission is achieved when the conditions provided for the incident electromagnetic wave to excite coupled surface waves on the both sides of the slab. These conditions require that the homogeneous overdense plasma, or the metallic film, is placed between two dielectric layers. Here, the ...
متن کاملAutomatic Tailoring of an Actor Profile Ontology
Knowledge tailoring is a powerful tool to customize a system according to the particular view and interests of the user, in such a way that usability of the system becomes significantly improved. In this paper, the tailoring of an actor profile ontology is discussed in the context of a HomeCare integrated system that is being designed and implemented in the EU K4Care project. The paper analyzes...
متن کاملUnstable Rotational States of Closed String with Massive Points
For the closed string carrying 2 or 3 point-like masses the stability problem for central and linear rotational states is considered. This problem is important for applications of these model to describing baryons, glueballs or other exotic hadrons. The linear rotational state correspond to an uniform rotation of the system with rectilinear string segments, connecting massive points. The state ...
متن کاملTransformed density rejection with inflection points
The acceptance-rejection algorithm is often used to sample from non-standard distributions. For this algorithm to be efficient, however, the user has to create a hat function that majorizes and closely matches the density of the distribution to be sampled from. There are many methods for automatically creating such hat functions, but these methods require that the user transforms the density so...
