We present a new program tool for interactive 3D visualization of some fundamental algorithms for representation and manipulation of
Bézier curves. The program tool has an option for demonstration of one of their most important applications - in graphic design for creating letters by means of cubic Bézier curves. We use Java applet and JOGL as our main visualization techniques. This choice ensures the platform independency of the created applet and contributes to the realistic 3D visualization....
Variance reduction has always been a central issue in Monte Carlo experiments. Population Monte Carlo
can be used to this effect, in that a mixture of importance functions, called a D-kernel, can be iteratively
optimized to achieve the minimum asymptotic variance for a function of interest among all possible mixtures.
The implementation of this iterative scheme is illustrated for the computation of the price of a European
option in the Cox-Ingersoll-Ross model. A Central Limit theorem as well...
This paper presents the main concept and several key features of the user-defined interface of COMSOL Java API for the solution of mechanical problems in fractured rock. This commercial computational system based on FEM has yet to incorporate fractures in mechanical problems.
Our aim is to solve a 2D mechanical problem with a fracture which is defined separately from finite-element discretization and the fracture properties are included through the constitutive laws. This will be performed based...
We study the theoretical and numerical coupling of two hyperbolic systems of conservation laws at a fixed interface. As already proven in the scalar case, the coupling preserves in a weak sense the continuity of the solution at the interface without imposing the overall conservativity of the coupled model. We develop a detailed analysis of the coupling in the linear case. In the nonlinear case, we either use a linearized approach or a coupling method based on the solution of a Riemann problem. We...
