Grammar induction refers to the process of learning grammars and languages from data; this finds a variety of applications in syntactic pattern recognition, the modeling of natural language acquisition, data mining and machine translation. This special topic contains several papers presenting some of recent developments in the area of grammar induction and language learning, as applied to vario...

This paper focuses on the airgap reluctances that connect stator and rotor teeth in a Magnetic Equivalent Circuit (MEC) model of an induction machine. A dimensionless analytical expression is adopted for the position dependence of these reluctances, the three degrees of freedom of which are identified and validated by Finite Element (FE) modelling, considering a simplified geometry and the comp...

Preliminary communication In this paper a fundamental mathematical model (algorithm) for determination of condition of induction machine as well as the simulation procedure for measurement of certain values in program MATLAB has been presented. A scheme of measuring system and results of simulation application are presented on output lists. Thus, measuring system gradually develops and improves...

Iron loss is a possible source of performance deterioration, especially for a torque regulation, in field oriented induction machine. In this paper, study on the model of an induction machine with iron losses, a flux estimation strategy, the design of direct and indirect field oriented controller, a precise torque regulation scheme and the determination of a core loss resistance are discussed. ...
