A variable-speed controller, for an existing 225 kW fixed-speed wind power generator, is presented in this paper. A sensorless direct torque control algorithm-based controller is proposed for the squirrel-cage induction generator. Generator torque reference is derived based on sensorless maximum power tracking mode algorithm, up to the base speed of the generator. A three-phase front-end converter is used here to deliver the generated power to the grid with unity-power-factor operation at all wind speeds. This algorithm is based on direct activ ....etc

Although there is good road safety performance the number of people killed and injured on our roads remain unacceptably high. So the roads safety strategy was published or introduced to support the new casualty reduction targets. The road safety strategy includes all forms of invention based on the engineering and education and enforcement and recognizes that there are many different factors that lead to traffic collisions and casualties. The main reason is speed of vehicle. We use traffic lights and other traffic manager to reduc ....etc

ABSTRACT
In today's fast moving World, the accidents are increasing at a very fast rate. One of the major causes of these accidents is over a speeding of vehicles. A major step has been taken rather to increase the road safety, so as to minimize the accidents

One of a major development was the introduction of speed cameras. This camera, usually containing radar, is electronic devices those working are still a mystery to most electronic hobbyists. The principle of these speed cameras is Doppler Eff ....etc

Abstract.
In this paper we propose a scheme for ball detection and tracking in
broadcast soccer video. There are two alternate procedures in the scheme: ball
detection and ball tracking. In ball detection procedure, ball candidates are first
extracted from several consecutive frames using color, shape, and size cues.
Then a weighted graph is constructed, with each node representing a candidate
and each edge linking two candidates in adjacent frames. Finally, Viterbi algorithm
is employed to extract the optimal path as ball’s l ....etc
