In this paper, a new algorithm for accurate optical flow estimation using discrete wavelet approximation is proposed. The image sequences are always assumed to be noiseless in the computation of optical flow, since there is always a method that can perform such tas

The purpose of this work is to reduce the data volume and to achieve a low bit rate in the digital representation of Low vision medical digital images (X-ray & MRI), without a perceived loss of image quality. In JPEG compression, it is passible to control the compression ratio and image quality by

An efficient and practical method for minimization of energy loss in electrical networks over intervals of time is presented. The proposed method uses different loading conditions during each given time interval instead of single snapshot loading of the network. The given interval is divided into sever

The multilevel voltage source inverters are recently applied in many applications such as ac power supplies and ac motor drives. The concept of multilevel voltage source inverter is explained. The concept of the harmonic elimination pulse-width-modulation (HEPWM) technique based on Walsh function is

As far as electrical power system is concerned, there has been a need to find out the future load in advance. Load forecasting has been a central integral process, throughout planning and operation of electrical utilities. An approach of artificial neural networks (multi layer perceptron) to short term

Load flow studies are important in power system planning, control and operating strategies when applied in real time mode. Comparative study between different load flow solution methods (the (Newton Raphson (NR), Fast De-coupled (FD)) conventional methods and Artificial Neural Network (ANN) method

In this paper discrete wavelet transform based orthogonal frequency division multiplexing (DWT-OFDM) system its proposed to improve the bandwidth efficiency by removing the cyclic prefix (CP). For further enhancement of performance of th

A new algorithm for reconstruction of a completely lost blocks using the 1-D discrete wavelet transform is proposed in this paper. Fading in wireless channels can cause the entire transmission of block-coded images to be received with errors and causing the information of the block to be lost. Instead

Thickness Deep drawing was carried out on circular blanks having a of (0.6 mm)from low carbon steel ( 0.07% C ) & dual phase steel using a conical diehaving die semi - angle of ( 20 ° ) and throat diameter of ( 13.8mm) withpunch of ( 12 mm ) diameter . Mixture of graphite powder & mineral oil wasused as a lubricant It was found that the limiting drawing ratio ( L. D. R ) forlow carbon steel is ( 2.79 ) at the blank diameter of ( 33.5 mm ) and deepdrawing was limited by fracture in the cups curvature at blank diameter of (34 mm ) while the limiting drawing ratio for the dual phase steel was ( 2.33 )at the blank diameter of ( 28 mm ) and deep drawing was limited by wrinklingin the flange of the cup . It was also found that the maximum drawing load fordual phase steel is greater than that for low carbon steel for all drawing ratios
