The condition for the DAE index to be higher than one is calculated symbolically. Using Analog Insydes a function for the computer algebra system Mathematica is written. It ...

In this paper the governing differential equations for coupled bending and torsional vibrations of a uniform beam possessing no cross sectional symmetry have been solved in ...

The coefficient matrix of 2-dimensional linear differential equation systems has complex eigenvalues and eigenvectors if and only if there are lines of attraction. The proof ...

The computer program ‘Fecom.nb’ implementing the Fedosov ∗-product in Darboux coordinates is presented. It has been written in Mathematica 6.0 but it can be easily ...

This guide covers Mathematica Version 6.0, which is a major upgrade to previous versions of the software. Several interactive features have been incorporated into the user ...

Machine element analysis has a goal of describing function and other aspects of machine elements in a theoretical form. This paper shows how ideas from object-oriented ...

Mathematica 5 contains new functionality that allows users to solve, possibly quantified, systems of equations and inequalities with domain restrictions on the variables. The ...

This paper introduces a numerical method with which it is possible to synthesize the element characteristic of a not specified circuit element or even a circuit block ("black ...

Several numerical methods, such as the finite element method, reduce applied mechanics and additional engineering problems to systems of linear algebraic equations. It has ...

MathModelica is a Mathematica extension, which provides a modeling, and simulation environment for Mathematica based on the new standard of physical modeling languages called ...
