Computer Program for Determining Optical Constants of a Film on an Opaque Substrate

Applied Optics, 1969
Abstract : A computer program is described that determines the optical constants of silver sulfide tarnish films on an opaque silver substrate. The program uses data from normal incidence reflectance measurements taken on two films of different thickness on silver. The sulfide film thickness were measured ellipsometrically.

MKVPCI: a computer program for Markov models with piecewise constant intensities and covariates

Computer Methods and Programs in Biomedicine, 2001
We present a computer program for fitting Markov models with piecewise constant intensities and for estimating the effect of covariates on transition intensities. The basic idea of the proposed approach is to introduce artificial time-dependent covariates in the data to represent the time dependence of the transition intensities, and to use a modified ...

Computer Program for a Double Exponential Equation to Determine Biological Constants

Journal of Pharmaceutical Sciences, 1967
A new computer program in Fortran II (with Format) for the equation, C = a 0 k a V d ( k a − k d ) ⋅ ( e − k d t − e − k a t ) , has been written. This program overcomes the problems of the previous programs published.

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 ...

General Computer Programs for the Determination of Formation Constants from Various Types of Data

, 1985
In chemical equilibrium studies it is often necessary to find an adequate model description, represented by the function f(x; β 1,..., β m ). Good agreement between the experimental data and the values calculated from that model is taken as evidence of having selected the best model. It should be noted immediately that this is not the only criterion by

Computer Program for Constant Pressure or Constant Volume Combustion Calculations in Hydrocarbon-Air Systems

Journal of Engineering for Power, 1977
A complete Fortran-II computer program is presented which can be used to compute the equilibrium composition and final state of the products after constant pressure or constant volume combustion in any hydrocarbon-air system.

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 ...

POLAG—a general computer program to calculate stability constants from polarographic data

Talanta, 1980
A general computer program, POLAG, that will calculate stability constants from polarographic data, has been written. The program requires no pretreatment of the experimental data. Any equilibrium model, consisting of species having the general formula M(m)H(j)(OH)(k)L(n)L'(p) may be fitted to the data. The performance and versatility of POLAG has been
