A general four-dimensional normal form of a double Hopf bifurcation is considered. As a particular case, the normal form of a forced (non-autonomous) non-linear oscillator ...

Under the assumption that a farmer employs precision farming equipment and methods for phosphorus fertilizer application in corn production, this study investigates the ...

The nonlinear free and forced vibrations of a simply supported, circular cylindrical shell in contact with an incompressible and inviscid, quiescent and dense fluid are ...

Amplitude equations are often used to describe marginally unstable phenomena in physical systems. Allowing for spatial modulation, the canonical forms for these equations are ...

An excellent article in the American Journal of Physics, by Fairen, Lopez, and Conde develops power series approximations for various systems of nonlinear differential ...

This graduate level course, which is offered every two years, is typically taken by about 15 students. The students are a mix of undergraduates and graduate students in ...

The accurate experimental determination of solid drug solubility in supercritical fluids (SCFs) and its correlation are crucially important to the development of ...

The main goal of this paper is to show how the computer algebra system Mathematica allows us to study and to develop some topics on Operator Theory. In particular, some ...

Thirty-nine detailed mechanisms for combustion of hydrogen, carbon monoxide and methanol are investigated using ReactionKinetics, a Mathematica based package published ...

Adapting a method recently proposed by C. Marboe and D. Volin for N=4 super-Yang-Mills, we develop an algorithm for a systematic weak coupling expansion of the spectrum of ...
