Confocal microscopy is a family of techniques that employ patterned illumination and synchronized imaging to create cross-sectional views of biological specimens. In this paper, we adapt confocal imaging to improving visibility underwater by replacing the optical apertures used in microscopy with arrays of video projectors and cameras. In our principal experiment, we show that using one project...

This paper addresses issues with computer simulation involved in designing illumination for architectural structures. In particular, the reflectance and transmittance of materials were studied respect to their influence on luminance values, thus directly power levels luminaires applied under particular projects. Raster images derived from digitally processed daytime pictures used precisely defi...

India shares the longest border with Bangladesh. The Indo-Bangladesh came into existence after India’s partition in 1947 which was finally called 1971. This is not carefully managed from its existence. Border management mainly started 1989. article discusses emergence of border.
