We have developed a three level implicit method for solution of the Helmholtz equation. Using the cubic spline in space and finite difference in time directions. The approach has been modied to drive Numerov type nite difference method. The method yield the tri-diagonal linear system of algebraic equations which can be solved by using a tri-diagonal solver. Stability and error estimation of the...

In this paper we investigate Object Oriented Binary Space Partitioning. The Binary Space Partition Tree (BSP-Trees) is a widely used and e ective data structure for solid modeling and hidden surface removal. We present algorithms for eÆciently constructing Object BSP Trees(OBSP) in 2-Dimensions. The term object used arises since the construction of our tree utilizes the property of hierarchical...

The clinical longevity of tooth-coloured restorations, whether direct or indirect, using composites and ceramics, greatly depends on the quality and stability of their marginal adaptation. In this issue, two interesting studies 7,15 bring this subject and lead us to an exciting discussion. Poor marginal adaptation of direct and indirect restorations exposes the dentin pulp complex to the oral e...

We want to study the perturbation growth of an initial seed of an ellipsoidal shape in Top-Hat collapse model of the structure formation in the Modied Chaplygin gas cosmology. Considering reasonable values of the constants and the parameters of the model under study, we can show that a very small deviation from spherical symmetry (ellipsoidal geometry) in the initial seed leads to a nal highly ...

connections, with a buer size of 32 and a pipe size of 50 packets, the relative shares of throughput were 31%, 39%, and 30%. This anomalous behavior can be removed by simply changing the congestion avoidance increase algorithm to read: cwnd += 1 / wnd With this change, bcwndc always increases by one in every epoch. For those who are interested in experimenting with the above algorithm, the modi...

in this paper, we introduce a new class of implicit functions and also common property (e.a) in modified intuitionistic fuzzy metric spaces and utilize the same to prove some common fixed point theorems in modified intuitionistic fuzzy metric spaces besides discussing related results and illustrative examples. we are not aware of any paper dealing with such implicit functions in modified intuit...

In this paper, we present a method for solving the rst kind Abel integral equation. In thismethod, the rst kind Abel integral equation is transformed to the second kind Volterraintegral equation with a continuous kernel and a smooth deriving term expressed by weaklysingular integrals. By using Sidi's sinm - transformation and modied Navot-Simpson'sintegration rule, an algorithm for solving this...

This paper is concerned with parameter estimation and inference in a cointegrating regression, where as usual endogenous regressors as well as serially correlated errors are considered. We propose a simple, new estimation method based on an augmented partial sum (integration) transformation of the regression model. The new estimator is labelled Integrated Modi…ed Ordinary Least Squares (IM-OLS)...

In this work, we conduct a comparative study among the combine Laplace transform and modied Adomian decomposition method (LMADM) and two traditional methods for an analytic and approximate treatment of special type of nonlinear Volterra integro-differential equations of the second kind. The nonlinear part of integro-differential is approximated by Adomian polynomials, and the equation is reduce...
