Solving 2D Reaction-Diffusion Equations with Nonlocal Boundary Conditions by the RBF-MLPG Method
Tập 25 - Trang 521-529 - 2014
This paper is concerned with the development of a new approach for the numerical solution of linear and nonlinear reaction-diffusion equations in two spatial dimensions with Bitsadze-Samarskii type nonlocal boundary conditions. Proper finite-difference approximations are utilized to discretize the time variable. Then, the weak equations of resultant elliptic type PDEs are constructed on local subd......
Direct Simulation of Laminar–Turbulent Transition in a Viscous Compressible Gas Layer
Tập 25 Số 1 - Trang 27-48 - 2014
We present simulation results for oscillatory modes in supersonic flow past an aircraft with a hypersonic jet engine. The flow of viscous compressible gas is modeled by a quasi-gas dynamic (QGD) system of equations. A coordinate transformation is applied to adapt the computational region to the configuration of the compression shock in supersonic flow past an object. An original method is proposed......

Maximum approximation of the best guaranteed result in a two-level hierarchical game
Tập 6 - Trang 157-162 - 1995
We consider the well-known two-level hierarchical game between the center and the production divisions in the presence of uncontrolled external factors. The problem of the best guaranteed result for the center in this game is approximated by a maxmin problem with separable variables. A stochastic quasigradient solution method is considered.
Integral Equation Method in Electromagnetic-Sounding Inverse Problems
Tập 14 - Trang 345-349 - 2003
The use of the integral equation method in electromagnetic-sounding inverse problems is considered. Several approaches to the solution of these inverse problems are proposed.

A Bound on the Real Stability Radius of Continuous-Time Linear Infinite-Dimensional Systems
Tập 12 - Trang 359-368 - 2001
The article examines bounds on disturbance norms under which a linear infinite-dimensional dynamical system remains stable.
