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.

Estimation of the efficiency of road construction machines in the design [PDF]

open access: yesE3S Web of Conferences
The 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.
