The anisotropic approximations of the Henyey-Greenstein phase function for neutron transport equation [PDF]
The effect of anisotropic scattering on the eigenvalues of a multiplying (c >1) and non-multi-plying (c < 1) slab in one-speed neutron transport equation is studied.

Solute Transport Control at Channel Junctions Using Adjoint Sensitivity
Water quality control and the control of contaminant spill in water in particular are becoming a primary need today. Gradient descent sensitivity methods based on the adjoint formulation have proved to be encouraging techniques in this context for river ...

Test particle description of transport processes for states with a continuous mass spectrum [PDF]
Aiming at a description of transport processes where the dynamically generated width of the states is potentially large a transport equation beyond the quasiparticle approximation is derived in first order gradient expansion. An effective particle number

Radiative transfer of acoustic waves in continuous complex media: Beyond the Helmholtz equation [PDF]
Heterogeneity can be accounted for by a random potential in the wave equation. For acoustic waves in a fluid with fluctuations of both density and compressibility (as well as for electromagnetic waves in a medium with fluctuation of both permittivity and

Quantum master equation scheme of time-dependent density functional theory to time-dependent transport in nano-electronic devices [PDF]
In this work a practical scheme is developed for the first-principles study of time-dependent quantum transport. The basic idea is to combine the transport master-equation with the well-known time-dependent density functional theory.

Nonclassical Particle Transport in 1-D Random Periodic Media [PDF]
We investigate the accuracy of the recently proposed nonclassical transport equation. This equation contains an extra independent variable compared to the classical transport equation (the path-length $s$), and models particle transport taking place in ...
