If equilateral triangles are constructed outwards or inwards on the sides of any given triangle, then the centroids of these triangles are the vertices of an equilateral ...

What is the effect on the line of regression when one extra point is appended to the original set of data points? This question may arise when one is up-dating time series ...

We consider the two-dimensional quasi-steady Stokes flow of an incompressible Newtonian fluid occupying a time-dependent simply-connected region bounded by a free surface, ...

We show that the symmetry classes of torsion-free covariant derivatives ∇T of r-times covariant tensor fields T can be characterized by Littlewood-Richardson products ...

Solving nonlinear systems, especially algebraic polynomial systems, is a fundamental problem which occurs frequently in various models of science and engineering like ...

M@th Desktop (MD) is a bank of mathematical e-learning resources based on Mathematica, and running on Versions 4-6, developed at the University of Graz under the supervision ...

Taking into account uncertainties on data or parameters while certifying results of computations in terms of bounding of errors is a big challenge that has to be faced by ...

CalcLink is an add-on package that provides bidirectional connectivity with Calc, the spreadsheet component of the platform-independent OpenOffice suite. With CalcLink it's ...

Gröbner bases are special bases of polynomial ideals which are very important in computer algebra. Gröbner bases of toric ideals can be used to perform integer linear ...

The emission spectrum of HCN has been recorded at 1463 K using hot gas molecular emission (HOTGAME) spectroscopy in the wavenumber region of 2900–3500 cm1 with a ...
