A DRBEM model for microwave heating problems
Applied Mathematical Modelling, 1995 The paper deals with the model equation \(T_t = \Delta T + \gamma(T) |E|^2\), where \(T\) is the temperature, \(\gamma (T)\) the thermal absorptivity, and \(|E|\) the amplitude of the electric field, which is supposed to depend exponentially on the spatial variables (in two or three dimensions).

The Improved Moving Least‐Square Ritz Method for the One‐Dimensional Sine‐Gordon Equation
Mathematical Problems in Engineering, Volume 2014, Issue 1, 2014., 2014 Analysis of the one‐dimensional sine‐Gordon equation is performed using the improved moving least‐square Ritz method (IMLS‐Ritz method). The improved moving least‐square approximation is employed to approximate the 1D displacement field. A system of discrete equations is obtained by application of the Ritz minimization procedure.

Differential Quadrature Solution of Hyperbolic Telegraph Equation
Journal of Applied Mathematics, Volume 2012, Issue 1, 2012., 2012 Differential quadrature method (DQM) is proposed for the numerical solution of one‐ and two‐space dimensional hyperbolic telegraph equation subject to appropriate initial and boundary conditions. Both polynomial‐based differential quadrature (PDQ) and Fourier‐based differential quadrature (FDQ) are used in space directions while PDQ is made use of in ...
