Tytuł:: Infinite-horizon Markov control processes with undiscounted cost criteria: from average to overtaking optimality
Autorzy:: Hernández-Lerma, Onésimo
Vega-Amaya, Oscar
Powiązania:: https://bibliotekanauki.pl/articles/1339029.pdf
Data publikacji:: 1998
Wydawca:: Polska Akademia Nauk. Instytut Matematyczny PAN
Tematy:: uniform ergodicity
Lyapunov stability conditions
(discrete-time) Markov control processes
Poisson's equation
undiscounted cost criteria
Opis:: We consider discrete-time Markov control processes on Borel spaces and infinite-horizon undiscounted cost criteria which are sensitive to the growth rate of finite-horizon costs. These criteria include, at one extreme, the grossly underselective average cost

Opis:: Particle-in-cell (PIC) technique is a widely used computational method in the simulation of low density collisionless plasma flows. In this study, a new two-dimensional (2-D) electrostatic particle-in-cell solver is developed that can be applied to non-rectangular configurations.

Tytuł:: An analytical-numerical method for calculating the stationary thermal field in electrical systems with elliptical cross-sections

Opis:: In this article, an analytical-numerical approach to calculating a stationary thermal field in the elliptical region is presented. The eigenfunctions of the Laplace operator were determined analytically, whereas the coefficients of the eigenfunctions were obtained numerically. The cooling was modeled with 3rd kind (Hankel’s) boundary condition, where the total heat transfer coefficient was the sum of the convective and radiative components. The method was used to analyze the thermal field in an elliptical conductor and a dielectrically heated elliptical column. The basic parameters of these systems, i.e. their steady-state current rating and the maximum charge temperature, were determined. The results were verified using the finite element method and have been presented graphically.
