THE METHOD OF FINDING POINTS OF INTERSECTION OF TWO CUBIC BEZIER CURVES USING THE SYLVESTER MATRIX
Journal Title: Silesian Journal of Pure and Applied Mathematics - Year 2016, Vol 6, Issue 1
Abstract
Sylvester matrix is used to create a 9th degree polynomial from coefficients of two cubic Bezier curves. The real roots of this polynomial allow to compute points of intersection of aforementioned curves. An additional constraint is used to indicate valid points. The “reverseinverse law” is presented in order to reduce the cost of calculation in this particular case. Also some limitations of the method as well as the ways to avoid them, if possible, are pointed out.

BASIC SUMS AS PARAMETERS CHARACTERIZING
We discuss the method of distributions’ characterization of geometric objects on the plane. The method is based on the basic sums. These basic sums perform the same role in description of image as the n-point correlation...
CHARACTERISTICS AND DECOMPOSITION OF EXPRESSIONS IN THE PF-NOTATION
The paper presents a selected aspects of classical parenthesis-free notation. With the introduction of the concepts of the pattern of expression and the characteristics were obtained convenient tools for classification a...
THE MODES OF A MIXTURE OF TWO NORMAL DISTRIBUTIONS
Mixture distributions arise naturally where a statistical population contains two or more subpopulations. Finite mixture distributions refer to composite distributions constructed by mixing a number K of component distri...

Theoretical and numerical modeling of flow transients in pipelines is a challenging field of research. The governing flow equations constitute a system of nonlinear hyperbolic partial differential equations enforcing the...
THE ULTRAMETRIC PROPERTIES OF BINARY DATASETS
Many multivariate algorithms commonly applied for binary datasets depend on a proper metric (i.e., dissimilarity function) imposed on binary vectors. In the following work the relationships between different metrics defi...
