This work aims to optimize the methods of light and electron microscopy for documentation of polymer composite samples. The main task was to adapt the well-known techniques of metallography (i.e. sample preparation and microscopic examination) to multi-component polymer materials. There were ...

We discuss bichromatic (two-color) front solutions to the bistable Nagumo lattice differential equation. Such fronts connect the stable spatially homogeneous equilibria with spatially heterogeneous 2-periodic equilibria and hence are not monotonic like the standard monochromatic fronts. We provide explicit...

In the past, public procurement has become a government policy tool through which support has been given to certain sectors, products or groups of entrepreneurs. Such support often directed to selected regions. The current public procurement trend is also supportive, but not directly&#x...

We discuss multichromatic front solutions to the bistable Nagumo lattice differential equation. Such fronts connect the stable spatially homogeneous equilibria with spatially heterogeneous n -periodic equilibria and hence are not monotonic like the standard monochromatic fronts. In contrast to the...

This paper is focused on a possible methodology for estimating of regression curve by nonparametric kernel regression approach. The main objective is a description of nonparametric regression function with using Nadaraya-Watson approach including a real data application for beer consumption in&#x...
