    Development of an automated handwriting analysis system
    (2011) Kamath, V.; Ramaswamy, N.; Navin, P.; Desai, V.; Kulkarni, S.M.
    In the present study a method has been proposed for the behavioral prediction of a person through automated handwriting analysis. The present work identifies the psychological traits in the writing namely size, slant and pressure, baseline, number of breaks, margins, speed of writing and spacing between the words. The handwriting is analyzed through Image Processing in MATLAB. The behavioral pattern of the person is predicted from the above traits of the handwriting. The developed system identifies handwriting closely which may not be possible for a graphologist. It is real time and involves less image preprocessing. The proposed system is calibrated with manual analysis. The results obtained through the system are in good agreement to more than 80 percent of the cases with ideal manual analysis. © 2006-2011 Asian Research Publishing Network (ARPN).

    Path Generation Techniques for Multi-Direction and Nonplanar Additive Manufacturing with an Industrial Robot
    (Institute of Electrical and Electronics Engineers Inc., 2024) Krishna, J.V.; Navin, P.; Guruprasad, K.R.
    A conventional Additive Manufacturing(AM) system always deposits the material in the direction of gravity. It requires support structures to print overhangs and produces staircase effects since the curved surfaces are approximated with parallel planes. A traditional AM system has three axes, where the material is deposited in the XY plane, and the print bed goes down in the Z direction upon printing one layer. In a gantry-type AM machine, the print head is stationary, and it can't orient. A multi-axis AM system can deposit the material in different directions and attain continuous curved paths. This paper presents the path generation methods for Multidirection and nonplanar robotic AM to eliminate support structures and staircase effects. © 2024 IEEE.
