Ai = Prismatic joints along the horizontal circular guide Bi = Spherical joints on the moving platform Ci = Prismatic joints on the vertical columns (i = 1,2,3) {F} = Fixed global reference frame {M} = Moving frame α, β, γ = ZYX Euler angles of rotation about the three joint axes of rider. α', β', γ', δ' = ZYXZ’ Euler angles of rotation about the four joint axes of chair on the moving platform ...

In the present investigation we have studied the peristaltic flow of a couple stress fluid in a non-uniform rectangular duct. The flow is investigated in a wave frame of reference moving with the velocity c away from the fixed frame. The peristaltic waves propagating on the horizontal side walls of a non-uniform rectangular duct is studied under lubrication approach. The exact solutions of velo...

We vary the quantization parameter in H.264 video encoding by increasing it by a well-chosen offset in every other frame, which we call reduced frames. As the motion compensation for a reduced frame is performed mainly from the previous frame (which is non-reduced), we obtain a large reduction in bit rate with only a small loss in video quality. We then develop an algorithm for the offset selec...
