Monte Carlo methods for radiation transport analysis on vector computers
(Elsevier, 1984)
The development of advanced computers with special capabilities for vectorized or parallel calculations demands the development of new calculational methods. The very nature of the Monte Carlo process precludes direct ...
Calculation of Photon‐Absorption Coefficient in Laser‐Produced Hydrogen Plasmas
(The American Institute of Physics, 1971-12)
The absorption coefficient for ruby‐laser photons in laser‐produced hydrogen plasmas is calculated for temperatures up to 5×105°K using second‐order perturbation theory. The calculations include inverse bremsstrahlung in ...
The influence of a plane boundary on the thermophoretic force in the knudsen regime
(Elsevier, 1987-05)
The effect of a plane diffusely reflecting wall on the thermophoretic force acting on a particle in the Knudsen regime is investigated. A general expression for the force on a particle in a nonuniform gas is given and then ...
Interpretation of dynamic scattering experiments on ternary polymer mixtures
(Elsevier, 1992)
The dynamics of a ternary polymer mixture consisting of either homopolymers A and B, or diblock copolymers A-B, in a matrix of homopolymers C, is studied using the random phase approximation and assuming incompressibility. ...
An investigation of nonlinear xenon oscillation by method of averaging
(Elsevier, 1973-12)
A nonlinear analysis of xenon-temperature controlled nuclear reactor dynamics is presented. The set of equations in question belongs to a general class of rate equations with quadratic nonlinearities. Boundedness of the ...
Temperature dependence of CsI(Tl) gamma-ray excited scintillation characteristics
(Elsevier, 1993-02-01)
The gamma-ray excited, temperature dependent scintillation characteristics of CsI(Tl) are reported over the temperature range of -100 to + 50[deg]C. The modified Bollinger-Thomas and shaped square wave methods were used ...
Spectral representations for the memory kernel characterizing self-diffusion
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1974-11)
Approximate spectral representations are developed for the memory kernel which characterizes self-diffusion. These spectral representations are based upon approximate eigenfunctions constructed via the Rayleigh variational ...
Theory of Self‐Diffusion in Classical Fluids: The Van Hove Self‐Correlation Function G8(r,t)G8(r,t)
(The American Institute of Physics, 1970-09)
Projection operator techniques have been applied to study the diffusion of a test particle in a classical many‐particle system such as a liquid or a plasma. Particular attention has been directed towards the calculation ...
DPM, a fast, accurate Monte Carlo code optimized for photon and electron radiotherapy treatment planning dose calculations
(IOP Publishing Ltd, 2000-08-01)
A new Monte Carlo (MC) algorithm, the `dose planning method' (DPM), and its associated computer program for simulating the transport of electrons and photons in radiotherapy class problems employing primary electron ...
