Моделі оптимальних інформаційних систем на двовимірних комбінаторних конфігураціях

This paper belongs to the field of systems engineering and is aimed at improving the qualitative indices of vector data information technologies (e.g. 2D vector data coding design) with respect to reliability, precision and other significant operating characteristics of the systems based on the combinatorial configurations theory, namely the Ideal Ring Bundles (IRB)s.

Seismicity of central part of Ukrainian shield in 2007 - 2013 period

Purpose. To perform a comparative analysis of record forms and earthquake spectrograms and explosions in quarries and mines what located in area of Kriviy Rih iron-ore basin (Kryvbas) for detection of seismic event signs of different nature this region with magnitude Mb ≥ 3,0 is the research object. Methods.

Structural Transformations of Collagen Containing Raw Materials under Alkaline Treatment

In the research of the rawhide structural transformations in chemical-and-colloidal processes under the action of alkaline dispersion, collagen of the dermis gets free of preservative agents and globular proteins. The conditions of rawhide alkaline treatment, under which the structure of a semi-finished product preserving amino-acid composition of collagen of the dermis is formed, have been outlined. A comparative analysis of the developed technologies of a leather semi-finished product formation from cattle rawhide has been carried out.
