Semiconformal symmetry- A new symmetry of the spacetime manifold of the general relativity
, 2019 In this paper we have introduced a new symmetry property of spacetime which is named as semiconformal curvature collineation, and its relationship with other known symmetry properties has been established.

Stereo image processing system for robot vision [PDF]
, 2009 More and more applications (path planning, collision avoidance methods) require 3D description of the surround world. This paper describes a stereo vision system that uses 2D (grayscale or color) images to extract simple 2D geometric entities (points,

Proper curvature collineations in non-static plane symmetric space-times
, 2010 The most general form of non-static plane symmetric space-times is considered to study proper curvature collineations by using the rank of the 6X6 Riemann matrix and direct integration techniques. Studying proper curvature collineations in each non static case of the above space-times it is shown that when the above space-times admit proper curvature ...
