Applying Lyapunov’s approach to the investigation of the stability of the motion according to first order approximation equations, the regions are singled out in the space ...

This paper introduces a visual framework in computational environment for displaying multi-region, multi-sector classical models, associated with authors such Isard, Chenery, ...

MathOptimizer is a Mathematica application package that provides tools for solving a very general class of global and local optimization problems. It is particularly suited ...

The two-dimensional kinetic model of the scrape-off layer recently suggested by Catto and Hazeltine [Phys. Plasmas 1, 1882 (1994)] is extended by allowing for ion recycling ...

In modern industrial manufacturing, a great amount of data is gathered to monitor and analyze a given production process. Intelligent analysis of such data helps to reveal as ...

The use of Mathematica in deriving mean likelihood estimators is discussed. Comparisons are made between the mean likelihood estimator, the maximum likelihod estimator, and ...

The 1D Heisenberg spin model with anisotropy of the XXZ type is analysed in terms of the symmetry given by the quantum Galilei group gamma q(1). For a chain with an infinite ...

Although much of the research done by modern physicists would be impossible without the use of computers, today’s physics curricula do not generally reflect their ...

In this paper we present a generic modeling strategy for the derivation of approximated symbolic expressions for small-signal characteristics of analog circuits. This ...

The Fril fuzzy data browser is a software tool which can automatically derive rules from large bodies of data. The data need not be completely known, and the derived rules ...
