Feature-based parametric modeling is the de facto standard in CAD. Boundary representation-based direct another CAD paradigm developed recently. They have complementary advantages and limitations, thereby offering huge potential for improvement towards an integrated scheme. Most existing integration methods are by industry typically treat edits as pseudo-features, where little can be said about...

In a distribution ray tracer, the crucial part of the direct lighting calculation is the sampling strategy for shadow ray testing. Monte Carlo integration with importance sampling is used to carry out this calculation. Importance sampling involves the design of integrand-specic probability density functions which are used to generate sample points for the numerical quadrature. Probability densi...

in this paper, three dimensional (3d) static and dynamic analysis of thick plates based on the meshless local petrov-galerkin (mlpg) is presented. using the kinematics of a three-dimensional continuum, the local weak form of the equilibrium equations is derived. a weak formulation for the set of governing equations is transformed into local integral equations on local sub-domains by using a uni...

ABSTRACT This paper presents the modification of a non-iterative algorithm for the component-oriented simulation of the dynamics of multibodies. Now the method can be implemented for the component-oriented simulation of the dynamics of CAD systems with redundant c...

in this paper, we solve the quadratic $alpha$-functional equations $2f(x) + 2f(y) = f(x + y) + alpha^{-2}f(alpha(x-y)); (0.1)$ where $alpha$ is a fixed non-archimedean number with $alpha^{-2}neq 3$. using the fixed point method and the direct method, we prove the hyers-ulam stability of the quadratic $alpha$-functional equation (0.1) in non-archimedean banach spaces.

In the information systems field, there is growing interest in the issue of method integration. The aim of this paper is to begin to build a framework for the understanding and evaluation of work in this area, using a new model of a method to analyse the 'method for method integration' and its resulting products. Introduction In the software engineering and information systems development commu...
