Abstract: Abstract This paper presents a general framework for the motion design of cam mechanisms using Non-Uniform Rational B-Spline (NURBS). The follower motion is described by the NURBS function. To establish motion curves, the system of… read more here.

Abstract: We study curve motion by the binormal flow with curvature and torsion depending velocity and sweeping out immersed surfaces. Using the Gauss-Codazzi equations, we obtain filaments evolving with constant torsion which arise from extremal curves… read more here.
