SEMI-DISCRETE CENTRAL DIFFERENCE METHOD FOR DETERMINING SURFACE HEAT FLUX OF IHCP [PDF]
Journal of the Korean Mathematical Society, 2007 A semi-discrete central difference method is employed in the time domain to solve an ill-posed boundary value problem. The method has wide application in determining the surface heat flux in a body to be determined from the temperature data measured at distanced locations. The method is based on the previous study of \textit{L.

Implicit Subspace Iteration to Improve the Stability Analysis in Grinding Processes
Applied Sciences, 2020 An alternative method is devised for calculating dynamic stability maps in cylindrical and centerless infeed grinding processes. The method is based on the application of the Floquet theorem by repeated time integrations. Without the need of building the
