In this paper we report the development of a symbolic computing tool for the automatic design of linear and nonlinear state observers for nth order nonlinear dynamical ...

This Mathematica notebook gives a collection of formulas/procedures for map projections and geodetic functions that I have used and studied. The formulas are defined and ...

CirclePack computes and display circle packings. Given a triangulation of a closed orientable surface it computes the corresponding circle packing. It will do this in ...

In the latest Calculus; by J. Stewart, we can notice many new problems which can be solved by using modern mathematical technologies, for example, Mathematica and Geometer's ...

The micro-geometry of surfaces is critical to the success of most manufacturing processes and the performance of manufactured products. Surfaces, such as those on mill rolls, ...

The Mathematica notebook, ContextFreeGrammar.nb, contains a command AcceptQ that takes a context-free grammar and a string as arguments and determines whether the string is ...

The Mathematica software package provides a range of tools for working with atomic and molecular systems. The symbolic tools include orthogonal polynomials and Clebsch-Gordan ...

We are presenting an algorithm capable of simplifying tensor polynomials with indices when the building tensors have index symmetry properties. These properties include ...

Contains many Mathematica programs for doing the geometry of curves in R2 and R3, and surfaces in R3. Examples include the computation of curvature, geodesics, minimal ...

A finite difference method and Gauss method of numerical integration are used to approximate the integro-differential system of an equation with the global error z(h)=O(h/sup ...
