A recursive estimation of depth from a sequence of images is proposed. Using the spherical projection, a simple equation is derived that relates image motion with the object motion. This equation is reformulated into a dynamical state space model for which Kalman filter can be easily applied to yield the estimate of depth. Point correspondences have been(More)
A comprehensive simulation on the optimization of the management of the non linear effects in long haul light wave systems has been carried out by chirped RZ format as the format has significant advantages over the RZ and NRZ modulation formats in WDM systems We have tried to demonstrate that a system reach of long-haul light wave link could be(More)
Our proposed project was mainly based on GSM networks and controller. Barometer is a well-organized tool for determining atmospheric pressure. The altimeter is a tool which calculates the vertical distance in accordance with a reference level. The barometric altimeter, computes the altitude according to the atmospheric pressure. Accuracy and size are the(More)

The direct torque control theory has achieved great success in the control of induction motor and Permanent Magnet Synchronous Motor. Many attempts have been made to implement the idea of DTC of induction motor to PMSM since 1990's.The DTC is implemented by selecting the proper voltage vector according to the switching status of inverter which was(More)
