    Surface tension of pentafluoroethane (HFC-125) (1994)
    Springer
    International journal of thermophysics 15 (1994), S. 941-948 
    Details
    ISSN: 1572-9567
    Keywords: capillary rise ; HFC-125 ; refrigerant ; surface tension
    Source: Springer Online Journal Archives 1860-2000
    Topics: Physics
    Notes: Abstract A set of accurate surface-tension data for HFC-125 has been obtained experimentally with both an absolute capillary rise technique and a differential capillary rise technique in the temperature range of 233.15–333.15 K. The purity of the experimental HFC-125 sample is 99.98 wt%. The two sets of experimental results with an absolute capillary rise method agree well with each other and, also, with the experimental results with a differential capillary rise method. The absolute deviations of experimental results with these two methods are within 0.01 mN · m−1. The relative deviation are within 0.2%. A van der Waals surface-tension correlation is also proposed.

    A Class of Nonmonotone Conjugate Gradient Methods for Unconstrained Optimization (1999)
    Springer
    Journal of optimization theory and applications 101 (1999), S. 127-140 
    Details
    ISSN: 1573-2878
    Keywords: Nonmonotone conjugate gradient method ; nonmonotone line search ; global convergence ; unconstrained optimization
    Source: Springer Online Journal Archives 1860-2000
    Topics: Mathematics
    Notes: Abstract In this paper, we introduce a class of nonmonotone conjugate gradient methods, which include the well-known Polak–Ribière method and Hestenes–Stiefel method as special cases. This class of nonmonotone conjugate gradient methods is proved to be globally convergent when it is applied to solve unconstrained optimization problems with convex objective functions. Numerical experiments show that the nonmonotone Polak–Ribière method and Hestenes–Stiefel method in this nonmonotone conjugate gradient class are competitive vis-à-vis their monotone counterparts.
