Computer program of calculation method for a constant-environment calorimeter

Thermochimica Acta, 1987
Abstract A computer program (in BASIC) for the determination of heats of solution and reaction in a constant-environment calorimeter has been developed. Particular attention was paid to the choice of parameters such as K / C and the endpoint of a generic calorimetric reaction in solution.

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 ...

Program PKAS: a novel algorithm for the computation of successive protonation constants

Canadian Journal of Chemistry, 1982
A new algorithm for the simultaneous determination of any number of protonation constants from potentiometric equilibrium data is described. This algorithm is characterized by a unique approach to the internal refinement of the constants and by the analytical nature of the numerical analysis whereby minimization is sought and achieved on the residuals

Host/Guest Interactions and NMR Spectroscopy. A Computer Program for Association Constant Determination

Journal of inclusion phenomena and molecular recognition in chemistry, 1997
A computer program is presented for the computation of association constants for host/guest compounds based on experimental data obtained from the NMR spectra of samples with different host/guest ratios of known concentration.

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

SUPERQUAD: an improved general program for computation of formation constants from potentiometric data

Journal of the Chemical Society, Dalton Transactions, 1985
A new computer program has been developed in which formation constants are determined by minimisation of an error-square sum based on measured electrode potentials. The program also permits refinement of any reactant concentration or standard electrode potential. The refinement is incorporated into a new procedure which can be used for model selection.

A computer program for determination of equilibrium constants and binding site concentrations in radioimmunoassay systems

Computer Programs in Biomedicine, 1980
We propose a method allowing the automatic determination of equilibrium constants and binding site concentrations for an immune serum composed of a series of homogeneous antibody subpopulations. It is then possible to decompose the 'Scatchard plot' in its straight components corresponding to each antibody subpopulation.
