A computer program for determination of thin films thickness and optical constants
Applied Surface Science, 2005 A computer simulation program for processing transmission spectra of amorphous optical thin films deposited on weakly absorbing substrates and evaluation of the refractive index n, extinction coefficient k and thickness d was developed. The computer code is the implementation of an optical characterisation algorithm based on the determination of the ...

A computer program to evaluate a counting loss correction constant in XRF analysis
X-Ray Spectrometry, 1981 Abstract Different sources of counting loss are described and the relation R t = R m exp ( R t τ) is considered valid for most ...

An improved computer program for the computation of formation constants from potentiometric data
Inorganica Chimica Acta, 1976 Abstract An improved version of the computer program MINIQUAD is described. The new program, MINIQUAD 75, is faster by a factor of 2–3 and more reliable in extreme cases. The programs are compared on a benchmark consisting of eight chemical problems.

Analytica Chimica Acta, 1986 Abstract The performance of five of the best-known computer programs LETAGROP, SCOGS, MINIQUAD, SUPERQUAD and ESTA, is critically discussed. All these programs are based on least-squares refinement procedures but differ in some important aspects: (a) the definition of the residuals function; (b) the minimization procedure; (c) the statistical and ...

A Computer Program for Estimation of the Constant Elasticity of Substitution Production Function
Applied Statistics, 1971 The paper describes a Fortran IV program for estimation of a non‐linear‐in‐the‐parameters production function known as the Constant Elasticity of Substitution (CES) model (see Arrow et al., 1961). This model, specified with multiplicative errors, is estimated by applying an approximate modified Newton method in which second‐order derivatives are not ...

Journal of Inorganic and Nuclear Chemistry, 1979 Abstract Two new computer programs are introduced which determine “best-fit” acid dissociation constants for di-, tri- and tetra-dentate ligands, and “best-fit” complex formation constants for complexes having a maximum order of two, three, or four.

Die Angewandte Makromolekulare Chemie, 1977 AbstractThe vinyl chloride batch suspension polymerization at constant polymerization rate governed by means of a temperature program, is presented.The method of establishing this temperature program by means of a digital computer, using the kinetic model proposed by Hamielec et al. for mass and suspension polymerization of vinyl chloride, is described.
