Modular nonblocking verification using conflict equivalence [PDF]
, 2006 This paper proposes a modular approach to verifying whether a large discrete event system is nonconflicting. The new approach avoids computing the synchronous product of a large set of finite-state machines.

Observation and Distinction. Representing Information in Infinite Games [PDF]
, 2020 We compare two approaches for modelling imperfect information in infinite games by using finite-state automata. The first, more standard approach views information as the result of an observation process driven by a sequential Mealy machine. In contrast,

Influence of frequency on the synchronous electrical machine parameters
Vestnik MGTU, 2018 The current and moment of resistance to rotation of the inductive synchronous electric machine under inductive load have been considered. For a synchronous machine with an inductive load, Theorem 1 is valid: the current amplitude in the inductive load of

Nonlinear Analysis of an Improved Swing Equation [PDF]
, 2016 In this paper, we investigate the properties of an improved swing equation model for synchronous generators. This model is derived by omitting the main simplifying assumption of the conventional swing equation, and requires a novel analysis for the ...

Vectorial formalism for analysis and design of polyphase synchronous machines [PDF]
, 2003 A vectorial formalism for analysis and design of polyphase synchronous machines without reluctance and saturation effects is described. We prove the equivalence of such a machine with a set of magnetically independent machines, which are electrically and
