    Springer

    Notes: Abstract For fractional programs involving several ratios in the objective function, a dual is introduced with the help of Farkas' lemma. Often the dual is again a generalized fractional program. Duality relations are established under weak assumptions. This is done in both the linear case and the nonlinear case. We show that duality can be obtained for these nonconvex programs using only a basic result on linear (convex) inequalities.

    A portable fault-tolerant parallel software MPEG-1 encoder (1996)
    Springer
    Multimedia tools and applications 2 (1996), S. 183-197 
    Details
    ISSN: 1573-7721
    Keywords: MPEG encoding ; parallel programming ; fault tolerance
    Source: Springer Online Journal Archives 1860-2000
    Topics: Computer Science
    Notes: Abstract MPEG video compression is quite difficult to achieve in real time, and hardware solutions for this problem are expensive. We present a portable, fault-tolerant, parallel, MPEG-1 encoder implemented in software. We detail the implementation strategy for the encoder and give performance results on a network of workstations and a massively parallel processor. We also show that our encoder can efficiently adapt to fluctuating processing power typical in workstation networks.
