Invariant Imbedding and Neutron Transport Theory IV-Generalized Transport Theory [PDF]
Indiana University Mathematics Journal, 1959 Abstract : The aim of the paper is to extend previous results and techniques so as to include an extensive category of transport processes involving deterministic and stochastic interactions and general geometries. Characteristic func tions and probabilities as well as expected values (fluxes) are determined. (Author)

Estimation of the efficiency of road construction machines in the design [PDF]
E3S Web of ConferencesThe reasons for the decrease in the efficiency of road construction machines are fluctuations in speed and load, deviations of which from the optimal value in terms of efficiency and causes an increase in energy losses and a decrease in efficiency.

Extrability as a strategy for successful employment of people with disability [PDF]
SHS Web of Conferences, 2022 This research is one of the attempts to understand the phenomenon of extrability, which means additional opportunities for people with disability, which are formed in the process of successful social adaptation and socialization, thanks to which people ...

Multiband effects in equations of motion of observables beyond the semiclassical approach
New Journal of Physics, 2019 The equations of motion (EOM) for the position and gauge invariant crystal momentum are considered for multiband wave packets of Bloch electrons. For a localized packet in a subset of bands well-separated from the rest of the band structure of the ...

Quasiclassical theory of charge transport in disordered interacting electron systems [PDF]
, 2003 We consider the corrections to the Boltzmann theory of electrical transport arising from the Coulomb interaction in disordered conductors. In this article the theory is formulated in terms of quasiclassical Green's functions.

The High-Density Symmetry Energy in Heavy-Ion Collisions and Compact Stars
Universe, 2018 High-density nuclear symmetry energy is of crucial importance in astrophysics. Information on such energy has been obtained from mass–radius determinations of neutron stars (NSs), and in the future NS mergers will increasingly contribute.

Hydrodynamic transport functions from quantum kinetic theory [PDF]
, 2000 Starting from the quantum kinetic field theory [E. Calzetta and B. L. Hu, Phys. Rev. D37, 2878 (1988)] constructed from the closed-time-path (CTP), two-particle-irreducible (2PI) effective action we show how to compute from first principles the shear and
