Abstract: This paper presents a new algorithm to remove misalignment of scanned Braille pattern using image processing. It is known that because of scanner imperfections, error occurs in scanned Braille pattern document. In this paper indexing method has been used for fixing the corner pixel value of tilted Braille pattern. The proposed work employs basic triangular property. Thereby we have calculated the angle by which the corner dots have been thrown out of alignment on a respective side. Since a variety of different Braille patterns are available, some being regular and exactly symmetrical, sorting method is used for symmetrical and unsymmetrical Braille pattern. This simulation has been carried out in MATLAB (R 2010a) and yields almost perfect results with acceptable errors and removes misalignment of Braille pattern.

Abstract: This study examines the use of Geosynchronous satellites for collecting sunlight, harnessing it to produce solar power and transmitting the generated power back to Earth using Wireless power transmission(WPT), safely and reliably. The advantage of placing solar cells in space is the 24 hour availability of sunlight. Also the urgency of finding an alternative energy source due to the depleting energy resources on earth calls for Space Based Solar Power. Here we study the concept of Solar Power Satellites (SPS), investigate the feasibility of implementation, the overall architecture & the underlying components. The results highlight the effectiveness of this system as an environment friendly, low-loss and large-scale method of energy transfer.
