Generally, various types of ultra-subharmonic motions can be observed in numerical simulations of periodically forced, non-linear oscillators. However, theoretical ...

For several years the Chair of Higher Mathematics of the USTU and Ural-multimediacenter of USTU have been developing and using computer technologies for math learning. There ...

The logistic curve is presented as a mathematical model for population growth in calculus, differential equations and mathematical modeling textbooks. However, there is ...

We provide explicit presentations of members of a suite of R matrices arising from the (\dot{0}_m|\alpha) representations of the quantum superalgebras U_q[gl(m|1)]. Our ...

The Banach-Tarski Paradox asserts that a solid ball in 3-space may be decomposed into five disjoint sets that can be rearranged to form two solid balls, each the same size as ...

Statistical methods to classify products as acceptable or not have been developed to insure an outgoing quality level under non-desctructive testing. Control procedures are ...

Over the last two decades anomalous relaxation and diffusion processes have been studied from both the experimental and theoretical point of view. Anomalous transport ...

In this paper, we introduce the Banzhaf power indices for simple games on convex geometries. We define the concept of swing for these structures, obtaining convex swings. The ...

The package TTC (Tools of Tensor Calculus) implements the majority of the basic tools of tensor and exterior calculus in a differentiable manifold using the point-of-view of ...

We discuss the capabilities of MathLie in supporting the symmetry analysis of differential equations. MathLie is a computer algebra program written in Mathematica 3.0 and ...
