    Fitting and using growth curves (1981)
    Springer
    Oecologia 49 (1981), S. 293-299 
    Details
    ISSN: 1432-1939

    Topics: Biology
    Notes: Summary A technique is presented for fitting and analyzing growth patterns using Gompertz, power, and exponential curves. Data collection involves measuring growth rate as a function of size. This is useful because growth rates at many different sizes can be measured at the same time, which removes the effect of environmental change from the observed growth pattern. Using size instead of age as the independent variable is important because size is usually more closely related to growth rate than is age. The particular technique presented here yields estimates of the variance of the curve parameters so that growth curves for different populations can be compared.

    Elektrischer Widerstand von metastabilenAg, Fe- undCu, Fe-Legierungen bei tiefen Temperaturen (1975)
    Springer
    The European physical journal 22 (1975), S. 117-120

    Topics: Physics
    Notes: Abstract Ag, Fe undCu, Fe alloys of high concentration (up to 20 at %), which cannot be produced as solid solution in bulk, are produced by the simultaneous condensation of both the components on a substrate at a temperature of 4.2 or 78 K. By cooling the two alloys show a minimum and a maximum of the electric resistance, both dependent on concentration and annealing temperature. In contrast toAg, Fe theCu, Fe alloys with more than 3,5 at % show an additional minimum at temperatures between 10 and 1 K, which disappears if the samples are annealed at 380 K.

    The Fix-Heiberger procedure for solving the generalized Ill-conditioned symmetric eigenvalue problem (1992)
    New York, NY : Wiley-Blackwell
    International Journal of Quantum Chemistry 41 (1992), S. 387-397 
    Details
    ISSN: 0020-7608
    Keywords: Computational Chemistry and Molecular Modeling ; Atomic, Molecular and Optical Physics
    Source: Wiley InterScience Backfile Collection 1832-2000
    Topics: Chemistry and Pharmacology
    Notes: We review a formalism introduced by Fix and Heiberger in 1972 for solving the generalized (or nonorthogonal) eigenvalue problem for ill-conditioned symmetric matrices and we discuss its application in quantum chemistry. A few examples dealing with the calculation of high Rydberg orbitals are presented.
