Artificial Vision System for the Blind using Ultra Sonic Wave transmission reception techniques
Abstrct:
The various systems have been developed to help blind individuals orienting in the surround space. The range of these systems is very wide and stretches from the simplest, inexpensive devices to the complex, multi-component vision systems which transforming the optical camera images into electric signals and transmit them to the cerebral cortex via implanted electrodes. However, these systems are very complex, expensiv ....etc

WIND BASED MEASUREMENT AND UNCERTAINITY ANALYSIS USING ULTRA SONIC SENSORS WITH KALAMAN FILTERING
ABSTRACT
Strong growth figures prove that wind is now a mainstream option for new power generation. All the successful megawatt-class wind technology developments to date are results of evolutionary design efforts based on the premise that control can significantly improve energy capture and reduce dynamic loads. The main challenge is wind stochasticity that impacts both power quality and drive train fatigue life for a ....etc

Detection of corrosion damage in aircraft wing skin structures is an ongoing NDT challenge. Ultrasonic methods are known and well-accepted techniques, which are relatively simple to carry out in terms of setup, probes and instrumentation and operator training. However, with conventional inspection from the top surface using a transducer at normal incidence (0o to the normal to the surface) producing a visual picture in the form of a C-scan, it is very tie consuming to point-by-point inspects large aircraft wing skin areas. In addition it is too ....etc

ULTRA SONIC motor is a newly developed motor, and it has excellent performance and many useful features, e.g.: high-torque density, low speed, compactness in size, no electromagnetic interferences, and so on. USM is a kind of piezo motor. The proposed speed control scheme is assumed for these applications because they require quick and precise speed control of actuators for various load conditions. A speed control method of USM using adaptive control is proposed.
Artificial Neural Network (ANN), which follows the biological neural cells in bra ....etc
