Integral transport methods. The integral transport methods construct an expression for the angular flux at a given location by integrating over all external and scattering sources that could contribute, taking in account the probability of the source neutral reaching the given location without a collision. The collision probability method result from partitioning the domain of the problem into a large number of finite size regions and formulating the equation to calculate the average value of the neutral flux in each region. Like the Monte Carlo method, the result of collision probability method can be very accurate. This method has been successfully implemented for neutral propagating in 3D rectangular grids. Since the collision probability method is based on a global particle balance, the neutral flux at a given region is coupled to the neutral scalar flux of any other regions via collision probabilities which must be calculated by multi-dimensional numerical integration involving expensive evaluation of Bickley functions.  3, record 4, English, - collision%20probability%20method

Dans la méthode de résolution par probabilité de collision, on découpe l’espace en éléments de volumes V_i, que l’on va considérer comme homogènes, et l’on calcule les facteurs de probabilité de collision qui représentent la probabilité qu’un neutronémis dans le volume V_i subisse sa première interaction dans le volume V_j. On entend par neutron émis dans V_i tout neutron qui y a été créé ou dont les caractéristiques (énergie, direction) y ont été modifiées suite à une diffusion ou à une autre interaction.  1, record 4, French, - m%C3%A9thode%20de%20r%C3%A9solution%20par%20probabilit%C3%A9%20de%20collision

The integrals in (4.2) are evaluated numerically, after discretization over the vertical grid, considering the atmosphere as a pile of homogeneous layers. As the cooling rate is strongly dependent on local conditions of temperature and pressure, and energy is mainly exchanged with the layers adjacent to the level where fluxes are calculated, the contribution of the distant layers is simply computed using a trapezoidal rule integration, but the contribution of the adjacent layers is evaluated with a two-point Gaussian quadrature ...  3, record 6, English, - Gaussian%20quadrature
