A WENO re-averaging (or re-mapping) technique is developed that converts function averages on one grid to another grid to high order. Nonlinear weighting gives the essentially non-oscillatory property to the re-averaged function values. The new reconstruction grid is used to obtain a standard high order WENO reconstruction of the function averages at a select point. By choosing the reconstructi...

We present a new third-order central scheme for approximating solutions of systems of conservation laws in one and two space dimensions. In the spirit of Godunov-type schemes, our method is based on reconstructing a piecewisepolynomial interpolant from cell-averages which is then advanced exactly in time. In the reconstruction step, we introduce a new third-order, compact, CWENO reconstruction,...

third-degree perineal lacerations in 7 mares were repaired surgically by a one-stage method (goetz technique). primary healing occurred in all of them without any complication. the conception rate obtained after surgery was 70.1%. five horses out of seven got pregnant after surgery and no further injury was seen at subsequent foaling. three mares have produced several healthy foals without any ...

Finite difference WENO schemes have established themselves as very worthy performers for entire classes of applications that involve hyperbolic conservation laws. In this paper we report on two major advances that make finite difference WENO schemes more efficient. The first advance consists of realizing that WENO schemes require us to carry out stencil operations very efficiently. In this pape...

In this paper we propose a third order accurate finite volume scheme based on polynomial reconstruction along with a posteriori limiting within an Adaptive-Mesh-Refinement (AMR) simulation code for hydrodynamics equations in 2D. The a posteriori limiting is based on the detection of problematic cells on a so-called candidate solution computed at each stage of a third order Runge-Kutta scheme. S...

vital decisions made at the strategic level in an organization are not only intricate but also costly to alter. it is therefore important to find a comprehensive approach to deal with such a possibility. one of the major problems of a common balanced scorecard (bsc)-based model in strategic management is lack of a ranking system for strategic objectives in order to enable prioritization of the ...
