Abstract The aim of this work is to design an algorithm which combines between steganography and cryptography that can hide a text in an image in a way that prevents, as much as possible, any suspicion of the hidden text The proposed system depends upon preparing the image data for the next step (DCT Quantization) through steganographic process and using two levels of security: the RSA algorith...

The combination of the remote-area-diesel generators with a battery storage and renewable energy source such as photovoltaic (PV) can greatly overcome the problems of these generators. In this paper a PV/Diesel generator hybrid energy system is sized to meet the load for about 100% availability. Where, for a given load characteristic and a given diesel generator a methodology is developed to op...

Optical character recognition systems improve human-machine interaction and are urgently required for many governmental and commercial departments. A considerable progress in the recognition techniques of Latin and Chinese characters has been achieved. By contrast, Arabic Optical Character Recognition (AOCR) is still lagging although the interest and research in this area is becoming more inten...
