We investigate the influence of the shape parameter in the meshless Gaussian RBF finite difference method with irregular centres on the quality of the approximation of the Dirichlet problem for the Poisson equation with smooth solution. Numerical experiments show that the optimal shape parameter strongly depends on the problem, but insignificantly on the density of the centres. Therefore, we su...

Abstract In the present paper, we construct a new class of operators based on type Bézier bases with shape parameter λ and positive s . Our include some well-known operators, such as classical Bernstein, α -Bernstein, generalized blending -Bernstein special case. this prove approximation theorems for these operators. Approximation properties our are illustrated graphs variables , n It should be...

the logistic, gompertz, richards and asymmetric logistic growth curve models were fitted to body weight data of local ghanaian chickens and french sasso t44 chickens. all four growth models provided good fit for each sex by genotype growth data with r2 values ranging from 86.7% to 96.7%. the rate constant parameter, k, ranged between 0.137 and 0.271 and were significantly different from zero fo...

In this paper, we study several approximation properties of Szasz-Mirakjan-Durrmeyer operators with shape parameter ??[?1,1]??[?1,1]. Firstly, obtain some preliminaries results such as moments and central moments. Next, estimate the order convergence in terms usual modulus continuity, for functions belong to Lipschitz type class Peetre's K-functional, respectively. Also, prove a Korovkin theore...
