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

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.

ELECTRONIC DEVICE FOR BLIND MOBILITY AID
INTRODUCTION
Many people with visual impairments can travel independently, using a wide range of tools and techniques.
Blind people are faced with many problems such as independent and graceful travel.
A long cane is used to extend the user's range of touch sensation.
It is usually swung in a low sweeping motion, across the intended path of travel, to detect obstacles.
However, techniques for cane travel can vary depending on the user ....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

Abstract
Blind people need to become as independent as
possible in their daily life in order to guarantee a fully social
inclusion. Mobility means the possibility of freely moving,
without support of any accompanying person, at home, in public
and private buildings, and in open spaces, as the streets of the
town. Mobile and wireless technologies, and in particular the
ones used to locate persons or objects, can be used to realize
navigation systems in an intelligent environment. Such systems
open new opportunities to improve th ....etc

F-Function Lobe Balancing for Sonic Boom Minimization
The early sonic boom theory defined the F-function distributions for two-shock (bow and tail) signatures with minimum impulse, minimum overpressure, or minimum bow-shock overpressure. The cross-sectional area distributions for wing-body wind tunnel models were derived using the iterative methods. But these methods have a disadvantage that a two shock ground signature, which being the worst case of the system is optimeised by these methods. the ground-signature parameter is physical ....etc
