3-D surface morphology measurements of compact graphite irons were used to analyze the fractal characteristics of the surfaces to relate the dry sliding surface morphology to the fractal dimension. The measurements show that the fractal dimensions (Df) of the sliding surfaces vary from 1 ...

In this paper, we study on the application of radical B-spline wavelet scaling function in fractal function approximation system. The paper proposes a wavelet-based fractal function approximation algorithm in which the coefficients can be determined by solving a convex quadratic programming problem....

Off-ramp area congestion and off-ramp queue spill over are wide-spread reasons for expressway traffic jams in China. A control strategy was developed to reduce the number of collisions between expressway and surface street vehicles and to reduce spill over by controlling the surface street vehicles ...

To combat packet loss and realize robust video transmission over Internet and wireless networks, a new multiple description (MD) video coding method is proposed. In the method, two descriptions for each video frame is first created by group of blocks (GOB) alternation. Motion information is then dup...

Streaming video is becoming increasingly popular among Internet multimedia applications. A robust coding scheme for DCT-based scalable video streaming over the Internet is proposed in this paper. Compared with conventional MPEG4-PGS (fine granular scalable) and progressive FGS(PFGS), the proposed me...
