In previous parts of this series [Mettes et al. (2004). Acta Cryst. A60, 621-636; McClurg & Keith (2010). Acta Cryst. A66, 38-49] a method for constructing global phase diagrams (GPDs) for molecular crystals was developed and the method was applied to single-component ordered crystal structures of tetrahedral molecules. GPDs are useful for visualizing what types of crystal structures a given mo...

This paper applies genetic algorithms to the problem of induction motor parameter determination. Generally available manufacturers published data like starting torque, breakdown torque, full load torque, full load power factor etc, are used to determine the motor parameters for subsequent use in studying machine transients. Results from several versions of the genetic algorithm are presented as...

This paper presents the modelling and parameter determination of an induction motor. The dynamic induction motor model was derived in relatively simple terms by using the concept of space vectors in d-q variables based on two-axis theory equations and the space phasor notation. A synchronous reference frame in which rotor flux lies on the d-axis was chosen with simplified dynamic equations and ...
