In classical kinetic models a particle free path distribution is exponential, but this is more likely to be an exception than a rule. In this paper we derive a generalized linear Boltzmann equation (GLBE) for a general free path distribution in the f

We investigate the question whether the D 1 approximation to the linear Boltzmann equation (LBE) can be used as an amendment to the diffusion approximation instead of the P 1 and P 1 / 3 solutions. We study two initial value problems in 3D: for a loc

A technique of the shape optimization of radiant enclosures with specular-diffuse surfaces is proposed. The shape optimization problem is formulated as an operator equation of the first kind with respect to a surface to be optimized. The operator equ

We consider the model of heat conduction, based on the first-order approximation to the dual-phase-lag (DPL) constitutive relation. This model is described by the Jeffreys-type equation. We study an initial value problem for the three-dimensional Jef

Optimal shape design problems of steady-state radiative heat transfer are considered. The optimal shape design problem (in the three-dimensional space) is formulated as an inverse one, i.e., in the form of an operator equation of the first kind with

Procedures for the preparation of bevels and the determination of their geometrical parameters have been developed. Using these procedures study of compositional and optical spatially resolved inhomogeneities of AlxGa1−xN layers grown on (0001) sap

The diffusion equation (DE) is widely used for approximate description of non-anomalous diffusion and Brownian motion (BM). However, the DE is wrong in describing the mean-square displacement (MSD) of a particle at small values of time, where the MSD
