Comparing Transition Systems with Independence and Asynchronous Transition Systems [PDF]

open access: yes, 1996
Transition systems with independence and asynchronous transition systems are noninterleaving models for concurrency arising from the same simple idea of decorating transitions with events. They differ for the choice of a derived versus a primitive notion

Accounting for the effects of saturation of magnetic circuits for the mechanical characteristics of asynchronous traction engines

open access: yesTrudy Odesskogo Politehničeskogo Universiteta, 2014
The tangential and radial dynamic inductances on properties of asynchronous traction motors are investigated. Possibility of using the method of dynamic inductances at construction of mathematical model of asynchronous traction motor is shown.

ANALYTICAL SOLUTION FOR A SIX-MASS THERMODYNAMIC MODEL OF A TEFC INDUCTION MOTOR

open access: yesИзвестия Томского политехнического университета: Инжиниринг георесурсов, 2022
The relevance of the study is determined by the fact that the thermal operating modes of asynchronous motors largely determine their reliability. Currently, the issues of calculating the steady-state thermal modes of engines are well developed.
