RESEARCH OF THE FACTORS INFLUENCING THE OPERATIONAL PERFORMANCE OF URBAN PUBLIC TRANSPORT [PDF]

open access: yesAvtomobilʹnyj Transport (Harʹkov), 2021
Problem. Currently, there is no universal approach to improve the efficiency of the urban public transport operation. Different methods are used during the estimation of public transport operation cost and the quality of services for the passengers.

Transport Theory [PDF]

open access: yesJournal of Physics and Chemistry of Solids, 1959
The usual theories of electrical conductivity suffer from a number of weaknesses. A more general theory will be described which gives the entire density matrix of a system of charge carriers in the steady state. It will be shown that the usual theory is valid under certain limiting conditions, but that in general there are rather complicated ...

Transport theory with nonlocal corrections [PDF]

open access: yes, 1998
A kinetic equation which combines the quasiparticle drift of Landau's equation with a dissipation governed by a nonlocal and noninstant scattering integral in the spirit of Snider's equation for gases is derived.

On the Bilinear Second Order Differential Realization of an Infinite-Dimensional Dynamical System: An Approach Based on Extensions to M2-Operators

open access: yesFractal and Fractional, 2023
Considering the case of a continual bundle of controlled dynamic processes, the authors have studied the functional-geometric conditions of existence of non-stationary coefficients-operators from the differential realization of this bundle in the class ...

Time-Dependent Thermal Transport Theory [PDF]

open access: yesPhysical Review Letters, 2015
Understanding thermal transport in nanoscale systems presents important challenges to both theory and experiment. In particular, the concept of local temperature at the nanoscale appears difficult to justify. Here, we propose a novel theoretical approach where we replace the temperature gradient with controllable external black-body radiations.

Transport Theory of Massless Fields [PDF]

open access: yes, 1997
Using the Schwinger-Keldysh technique we discuss how to derive the transport equations for the system of massless quantum fields. We analyse the scalar field models with quartic and cubic interaction terms.
