A New Induction Motor V/f Control Method Capable of High-Performance Regulation at Low Speeds
Abstract
A novel open-loop speed control method for induction motors that provides high output torque and nearly zero steady-state speed error at any frequency is presented. The control scheme is based on the popular constant volts per hertz (V/f) method using low-cost open-loop current sensors. Only stator current measurements are needed to compensate for both stator resistance drop and slip frequency. The scheme proposed fully compen ....etc

ABSTRACT
Amaranthus spinosus Linn. complete plant material was extracted successively by petroleum ether, chloroform, methanol, and water. All the extracts were subjected to in vitro non-enzymatic haemo-glycosylation method, i.e. an oxidation reaction. The degree of haemoglycosylation in the presence of different extracts of Amaranthus spinosus were measured colorimetrically at 520 nm. The preventive effect of haemoglobin glycosylation at the two concentration; 0.5 and 1 mg/mL was estimated as follows: pet. ether; 13.1%, 16.4%, chlorof ....etc

Abstract:
The billions of dollars of Commercial banks losses to check frauds make automatic verification of signatures of checks a major requirement in the new Interbank Check Imaging(ICI) environment. In this seminar we shed some light on the problem of check fraud, and introduce the application of an ASV method to the security of the financial transactions in electronic banks. The problem of transferring ASV research into an applicable system that can be integrated into electronic banks environment, with its implications, is dealt with in ....etc

Abstract
Auto-focusing in imaging systems depends on
the determination of the correct image focus criterion. In this
research, the image captured by a liquid-filled diaphragm (LFD)
fluid lens was analyzed to determine a focus measure criterion
that can be used to establish the correct focus and thus quantify
the image quality. The LFD lens was actuated using a steppermotor
driven syringe mechanism. The lens diaphragm was made
of polydimethylsiloxane (PDMS) polymer that exhibit good
optical properties. The lens focal length was ....etc
