Accelerations of the discrete ordinate method for nadir viewing geometries [PDF]

AIP Conference Proceedings, 2013
In this paper we analyze several acceleration techniques for the discrete ordinate method with matrix exponential for the solution of the radiative transfer equation. These techniques include the left eigenvectors matrix approach for computing the inverse of the right eigenvector matrix, the telescoping technique, and the method of false discrete ...

Constructing an interval of Minkowski space from a causal set

, 2006
A criticism sometimes made of the causal set quantum gravity program is that there is no practical scheme for identifying manifoldlike causal sets and finding embeddings of them into manifolds.

Quasi-Random Discrete Ordinates Method for Transport Problems

, 2023
The quasi-random discrete ordinates method (QRDOM) is here proposed for the approximation of transport problems. Its central idea is to explore a quasi Monte Carlo integration within the classical source iteration technique. It preserves the main characteristics of the discrete ordinates method, but it has the advantage of providing mitigated ray ...
