The Estimation of Rate Constants in Systems of Linear and Nonlinear Differential Equations Using the Polynomial-approximated Least Squares-error and Iterative Search Technique

Abstract A new technique is proposed for estimating the rate constants in systems of linear or nonlinear differential equations, using a polynomial approximation of the observed concentrations of species participating in the reaction and an iterative search technique. The method is implemented by minimizing the errors of the concentrations (of species), as computed by the theoretical equations derived from the linear differential equations or by the trapezoidal averaging simulation, relative to those calculated by the polynomial approximation. The present technique requires the concentrations (at the initial reaction stage) of s-2 species (the s species takes part in the reaction). Two kinetic example, A\ightleftarrowsB\ightleftarrowsC and S+E\ightleftarrowsES→P, have been used to illustrate and develop the present technique.

ESTIMATING MECHANISM AND KINETIC RATE CONSTANTS USING ITERATIVE SEARCH TECHNIQUE I. ANATION REACTION OF AQUOPENTAAMMINERUTHENIUM(III) COMPLEXES IN AQUEOUS SOLUTION

Abstract The elementary reaction mechanism and the kinetic rate constants for the anation reaction of aquopentaammineruthenium(III) complexes are estimated by a new iterative search technique. The anation mechanism is well illustrated by the SN1 and SN2 combined reaction map. The five-coordinated species participates directly in the reaction as a momentarily living intermediate, and the seven-coordinated species seems to be allowed only in the transition state.

An application of search technique in truss configurational optimization

A hypothesis of unimodality and an efficient algorithm called iterative search technique are proposed in optimizing the configurations of determinate and indeterminate trusses under multiple loading conditions. Some of the results may be compared with Michell Structure and show good agreement.

Information dissemination and automatic information systems

Automatic information dissemination, search, and retrieval systems have become increasingly important in recent years, because of the urgency of the information problems themselves, and also because of a wide-spread feeling that computers can help in providing the much needed solutions. Over the past few years much has been learned about the design of automatic information systems and about the effectiveness of various types of analysis and search procedures. The present report reviews the principal techniques of interest and provides a forecast of the systems design and type of operations likely to be implemented in automatic information systems of the future. The information dissemination process is first examined in detail. The main functions and organization of information systems are then reviewed, and present capabilities are described using some of the currently existing operational systems as examples. Finally, future systems are considered, including in particular those based on automatic content analysis and on user-controlled searches. Specifically examined are author indexing and automatic analysis techniques, automatic typesetting and composition procedures, automatic and semiautomatic dictionary construction, and iterative search techniques.
