The methods that are developed in this paper for differencing the discrete ordinates equations
on a triangular xy grid are based on piecewise polynomial representations of the angular …

Three new difference schemes for solving the neutron transport equation are presented. In
some situations these new methods give smoother results than the diamond difference …

Although many different tests are used to diagnose myocardial contusion, the clinical
implications of the diagnosis are unclear. This makes it difficult to decide which patients require …

The effectiveness of the acceleration techniques known as coarse mesh re-balance and the
synthetic method is examined for the iterative processes of transport codes. These two …

Using projection operators, we rederive xy geometry discrete ordinates-to-spherical harmonics
(S N → P N-1 .) fictitious sources defined in the literature as ray-effect mitigating devices. …

A two-dimensional(x, y) tial mesh is currently under neutron transport code based on a triangular
spadevelopment at Los Alamos. This code w* 11 offer several advantages over present …

A class of finite difference methods known as alternating semi-implicit techniques is presented
for the solution of the multigroup diffusion theory reactor kinetics equations in two space …

… To simplify notation for the following analysis, we write all three sources simply as S , which
we will treat as a known quantity. Of course, S depends on the unknown flux ¥ , but we will …

… for each of the three geometries will be given. In the following development we will omit …
In this section, we will depart from the traditional usage of the diamond difference scheme and …

This volume contains a detailed biography of Elgar, and is part of the'Master Musicians' series
written by WH Reed. In writing this biography, Reed was aided by Elgar's daughter who …
