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

open access: closedJournal 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

open access: closedApplied 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

open access: closedTalanta, 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

A damped non-linear least-squares computer program (DALSFRK) for the evaluation of reaction rate constants

open access: closedJournal of the Chemical Society, Dalton Transactions, 1978
After consideration of the limitations of linear treatments for the analysis of kinetic data, a damped non-linear least-squares computer program (DALSFRK) is described. The program, which employs Marquardt's algorithm as the basis of minimisation, has been developed with the aid of synthetic data.

Computer programs for the determination of optical constants from transmission spectra and the study of absolute absorption intensities

open access: closedJournal of Molecular Structure, 2002
Abstract FORTRAN computer programs used in the determination of optical constants and other physical properties from transmission measurements have been written by the Jones and Bertie research groups. Over the last several years, C++ has emerged as the standard programming language and it has become desirable to convert these programs. In this paper,

Computer quadrature programs for the determination of best-fit acid dissociation and complex formation constants

open access: closedJournal 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.

Application of a computer temperature program to the vinyl chloride batch suspension polymerization at constant rate

open access: closedDie 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.

Exponential model for a regulatory enzyme. Computer program for the determination of the model constants from initial velocity data

open access: closedInternational Journal of Bio-Medical Computing, 1987
The paper describes a program (DESCENT) which evaluates the constants of the exponential model for a regulatory enzyme with up to four substrates or up to three substrates and one effector. The program operates by repetitive adjustment of the model constants so as to secure a better fit between the observed and calculated initial velocities of reaction.
