On the Stability of Fully-Explicit Finite-Difference Scheme for Two-Dimensional Parabolic Equation wcture of the transition matrix of a finite-difference scheme and demonstrate that depending on the parameters of nonlocal conditions the proposed method can be stable or unstable. The results of numerical experiment with one test problem are also presented and they validate theoretical results.

Chinese Chess Recognition Based on Log-Polar Transform and FFT, Fast Fourier Transform (FFT) can achieve translation-invariant. A simple measurement is used to assess the similarity after horizontal and vertical projection. Experiment results have shown that the algorithm can effectively recognize all chesses.

Adaptive Discontinuous Galerkin B-Splines on Parametric Geometriesl points of the B-spline approximations. That enables an efficient adaptive local refinement. Discrete B-splines are used for cascading conjugate gradient iterations. In addition, we provide results on single patches in two and three dimensions.
