Most algebraic calculations which one sees in linear systems theory, for example in IEEE TAC, involve block matrices and so are highly non-commutative. Thus conventional ...

We demonstrate the use of several code implementations of the Mellin-Barnes method available in the public domain to derive analytic expressions for the sunset diagrams that ...

Dark energy cosmologies with an equation of state parameter w less than -1 are often found to violate the null energy condition and show unstable behaviour. A solution to ...

A Mathlink interface to model reduction modules from the SLICOT library. It supports Balance & Truncate model reduction (BTA) AB09AD; Singular perturbation approximation ...

Ampcalculator (AMPC) is a Mathematica c based program that was made publicly available some time ago by Unterdorfer and Ecker. It enables the user to compute several ...

The application of a two-step hybrid technique to the geometrically nonlinear analysis of curved beams is used to demonstrate the potential of hybrid analytical techniques in ...

The application of a two-step hybrid technique to the geometrically nonlinear analysis of curved beams is used to demonstrate the potential of hybrid analytical techniques in ...

A dynamical system is, in its most general form, described by a system of six coupled first order differential equations which cannot be solved rigorously. An approximate ...

The BenderWu package allows for analytic computation of the perturbative series in 1D quantum mechanics around a harmonic minimum of the potential. The code is based on the ...

An automatic code is proposed for the perturbation analysis of strongly non-linear two-degree-of-freedom systems with cubic non-linearities. The recently proposed [1] ...
