Samples of 12 hard winter wheats and their flours that produced breads varying in crumb grain scores were studied for 38 quality parameters including: wheat physical and chemical characteristics; flour ash and protein contents,starch damage,swelling power,pasting characteristics,and flour particle size distribution; dough properties determined by a mixograph; and breadmaking properties for pup loaves (100g flour). Only two parameters,the protein content of wheat and the granulation of flour,showed significant correlations with bread crumb grain scores. Protein content of wheat ranging 12.9%～14.5% determined by an NIR method showed a weak inverse relationship (r =-0.61,p<0.05) with bread crumb grain score. Flour particle size distribution measured by both Alpine Air Jet Sieve and NIR methods revealed that the weight wt % of particles less than 38μm in size and representing 9.6%～19.3% of the flour weights was correlated positively (r =0 .78,p<0.01) with crumb grain score,whereas wt % of flour particles larger than 125μm had an inverse relationship (r =-0.60,p<0.05) with crumb grain score.

Induction motor driven by vector control method makes high performance control of torque and speed possible. The decoupling of flux and electromag netic torque obtained by field orientation depends on the precision and the accuracy of the estimated states. Rotor asymmetries lead to perturbations of air gap flux patterns in induction machines. These perturbations in flux compo nents affect the electromagnetic torque, as well as stator currents and voltages. This paper first investigates the control of the induction motor using an extended kalman filter （EkF） for a direct fieldoriented control. It then studies the broken rotor bars （BRBs） fault by the monitoring the rotor resistance. The hypothesis on which the detection is based is that the apparent rotor resistance of the motor will increase when a rotor bar breaks. The rotor resistance is estimated and value to detect BRBs fault. compared with its nominal The EkF estimates the rotor flux, speed and rotor resistance on line by using only measurements of the stator voltages and currents. Simula tion results show the effectiveness of the proposed method in the cases of load torque perturbation and speed reversion.

关键词： The present pagination reports both Brownian diffusion and thermophoresis aspects subject to magneto hydrodynamic Williamson fluid model. Assuming the flow is unsteady and blood is treated as Williamson fluid over a wedge with radiation. The governing equations are transformed into ordinary differential equations by using similarity variables. The analytical solutions of the transformed governing equations are obtained by using the Rk 4th order method along with shooting technique solver. The effects of various physical parameters such as Hartmann number local Weissenberg number radiation parameter unsteadiness parameter Prandtl number Lewis number Brownian diffusion thermophoresis wedge angle parameter moving wedge parameter on velocity temperature concentration skin friction heat transfer rate and mass transfer rate have been discussed in detail. The velocity and temperature profile deprives for larger We and an opposite trend is observed for concentration. The radiation parameter is propositional to temperature and a counter behaviour is observed for Pr.
