  • SimPle stochastic games and P-Matrix generalized linear comPlementarity Problems
    Lecture Notes in Computer Science, 2005
    Co-Authors: Bernd Gärtner, Leo Rüst
    Abstract:

    We show that the Problem of finding oPtimal strategies for both Players in a simPle stochastic game reduces to the generalized linear comPlementarity Problem (GLCP) with a P-Matrix, a well-studied Problem whose hardness would imPly NP = co-NP. This makes the rich GLCP theory and numerous existing algorithms available for simPle stochastic games. As a sPecial case, we get a reduction from binary simPle stochastic games to the P-Matrix linear comPlementarity Problem (LCP).

  • the friction and wear of electroless ni P Matrix with Ptfe and or sic Particles comPosite
    Tribology International, 2006
    Co-Authors: Hezhou Liu, Bin Shen, Lei Liu
    Abstract:

    Abstract In this PaPer, the friction behaviour and wear mechanism of electroless Ni–P Matrix with PTFE and/or SiC Particles comPosite coating are investigated by virtue of ring-on-disk wear machine at a high load of 150 N. The worn surface, wear debris and the comPosition changes after wear were characterized using scanning electron microscoPy (SEM) and energy-disPersive analysis of X-ray (EDAX). By comParison with Ni–P and Ni–P–SiC coatings, the results indicated that the combination of a PTFE-rich mechanical mixed layer (PRMML) formed on the worn surface and hard SiC were resPonsible for the good tribological ProPerties of the hybrid Ni–PPTFE–SiC comPosites at high load. After heat treatment at 400 °C for 1 h, the wear rate of Ni–P Matrix comPosites decreased with corresPonding increase in microhardness. During sliding, an obvious decrease in the temPerature rise with PTFE addition was attributed to the good anti-friction of PTFE.
