    Abstract: This paper propose a new method for improving shielding effectiveness (SE) of a rectangular enclosure with multiple circular apertures. In this method in order to compensate the effects of the apertures on (SE) parameter, we use two metallic walls each containing apertures instead of the one wall. By using two walls for shielding an enclosure, the ... Show More

    Abstract: This paper proposes a pixel-based compression algorithm for character digital image in improving the storage of characters in memory during system operation. In particular, in this algorithm, each character binary image in text is grouped by binary numbers and then encoded to reduce the character image capacity of the character compared to the orig...
