A numerical method may be used to obtain a quadratic Lyapunov Function for a high order system x= f(x), where f(x) is a continuous function of x, so that the vohtme of the asymptotic stability reagion obtained is maximised. Summary--This paper deals with the problem of automatically constructing a

β¦ Synopsis
This paper presents a novel, knowledge-based method for measuring semantic similarity in support of applications aimed at organizing and retrieving relevant textual information. We show how a quantitative context may be established for what is essentially qualitative in nature by effecting a topological transformation of the lexicon into a metric space where distance is well-defined. We illustrate the technique with a simple example and report on promising experimental results with a significant word similarity problem.

The Ewald method is applied to accelerate the evaluation of the Green's function (GF) of an infinite equispaced linear array of point sources with linear phasing. Only a few terms are needed to evaluate Ewald sums, which are cast in terms of error functions and exponential integrals, to high accurac
## The use of the microcomputer for the processing of analytical data in the laboratory is currently increasing. However, computational methods which have been used successfully on minicomputers may not be suitable for microcomputer implementation due to the lack of available precision. This paper
