In an unfavorable period of development the country's economy, various types subjective economic behavior, including labor, entrepreneurial, credit, savings are considered to be more relevant for periods well-being. However, degree its impact on other behavior is so great that it cannot ignored by decision makers in public governance and corporate management. The article analyzes existing relat...

Richardson extrapolation is applied to improve the accuracy of the numerical solution of boundary integral equations. The boundary integral equations arise from a direct boundary integral method for solving a Laplace’s equation interior Dirichlet problem. Specifically, the Richardson extrapolation is used to improve the accuracy of collocation. Numerical justification is provided to support the...

The Time Delay Control with Switching Action (TDCSA) method, which consists of Time Delay Control(TDC) and a switching action of sliding mode control(SMC), has been proposed as a promising technique in the robust control area, where the plant has unknown dynamics with parameter variations and substantial disturbances are preset. When TDCSA is applied to the plant with saturation nonlinearity, h...

In potential theory, the boundary element method is recognized as a powerful numerical tool. Usually it works with the simple fundamental solution based on the wholeor half-space scalar Green function. In the case of a uniform and isotropic domain connected only to isolated regions, a Fredholm integral equation of the second kind with respect to the potential can be derived [l, 21 which is solv...
