Combinatorial expression of LIM homeobox genes in subsets of embryonic motor neurons defines early stages in the topographic and functional organization of the spinal cord motor columns.

This paper deals with the synthesis of fuzzy state feedback controller of induction motor with optimal performance. First, the Takagi-Sugeno (T-S) fuzzy model is employed to approximate a non linear system in the synchronous d-q frame rotating with electromagnetic field-oriented. Next, a fuzzy controller is designed to stabilise the induction motor and guaranteed a minimum disturbance attenuati...

Motor neurons extend axons along specific trajectories, but the molecules that control their pathfinding remain poorly defined. We show that two LIM homeodomain transcription factors, Lim1 and Lmx1b, control the initial trajectory of motor axons in the developing mammalian limb. The expression of Lim1 by a lateral set of lateral motor column (LMC) neurons ensures that their axons select a dorsa...

Induction motor is a typical member of a multi-domain, non-linear, high order dynamic system. For speed control a three phase induction motor is modelled as a d–q model where linearity is assumed and non-idealities are ignored. Approximation of the physical characteristic gives a simulated behaviour away from the natural behaviour. This paper proposes a bond graph model of an induction motor th...

This paper proposes a modified dynamic equivalent circuit model for linear induction motor considering both longitudinal end effect and transverse edge effect. The (speed-dependent effect) is based on conventional Duncan’s approach. investigated by using three correction factors applied to the secondary resistance magnetizing inductance. Moreover, iron saturation effect, skin air-gap leakage ar...

Input frequency is one of the important variables in design and performance analysis of single-sided linear induction motors (SLIMs). Changing the frequency changes both the dimension of the SLIM in design process and the performance of the designed motor. The frequency influences the induced eddy currents in the secondary sheet as well as saturation level of the secondary back-iron. In this pa...

Tubular linear induction motor (TLIM) can be used as a capsule pump in a large pneumatic capsule pipeline (PCP) system. Parametric performance evaluation of the designed 1-meter diameter PCP-TLIM system yields encouraging results for practical implementation. The capsule thrust and speed inside the TLIM pump can be calculated from the combination of the PCP fluid mechanics and the TLIM equation...
