Low-Memory, Discrete Ordinates, Discontinuous Galerkin Methods for Radiative Transport [PDF]
SIAM Journal on Scientific Computing, 2020 The discrete ordinates discontinuous Galerkin ($S_N$-DG) method is a well-established and practical approach for solving the radiative transport equation. In this paper, we study a low-memory variation of the upwind $S_N$-DG method. The proposed method uses a smaller finite element space that is constructed by coupling spatial unknowns across ...

Low-energy electron transport with the method of discrete ordinates [PDF]
, 1971 The one-dimensional discrete ordinates code ANISN was adapted to transport low energy (a few MeV) electrons. Calculated results obtained with ANISN were compared with experimental data for transmitted electron energy and angular distribution data for ...

Analysis of stray current induced by cathodic protection on steel-framed masonry structures [PDF]
, 2011 Cathodic protection (CP) has been successfully employed to protect steel-framed masonry buildings from corrosion related damage. When a CP system is installed to protect the structural members, other metallic items which are within the fabric of the ...
