The Solar Energy is produced by the Sunlight is a renewable source of energy which is eco- friendly. Every hour enough sunlight energy reaches the earth to meet the world’s energy demand for a whole year. In today’s generation we needed Electricity every hour. This Solar Energy is generated by as per applications like industrial, commercial, and residential. In this article, we have reviewed about the Solar Energy from Sunlight and illustration given to estimate the parameters for solar energy set up.

Braille is the language used by visually impaired persons. Braille language comprises of collection of Braille cells which are embossed on a metal plate. Maintaining these bulky metal plates and distributing them to other parts of the world is a challenging task. This paper proposes a new technique of translating the Braille Cells embossed on plate to a natural language English character which can be easily distributed over network to make it globally accessible. Initially Braille documents are scanned, and preprocessing techniques like adaptive histogram and Laplacian filters are applied to augment the dots by eliminating the noise. The existence of dot pattern in every cell is detected with a Threshold and transformed to sequence of Binary matrix. A cell information is translated to 3x2 matrix with binary values of 0’s and 1’s representing absence and presence of dots in a cell. Convolutional Neural Network is used for feature extraction and Classification and Regression Trees (CART) classifier is utilized for recognize the character.
