Increase in an Entropy of a Code Word in the Binary Channel With Constant Duration

Transmission and perception of information are based on property of matter — reflection. Reflection is objective material process as a result of which system “A” interacting with system “B” reflects its image by change of the properties or acquires the new properties connected to closeness of system “B”. Therefore, the content of reflection is defined by features of the displayed system “B”, and the form of reflection — change of properties of the perceiving system “A”.

Segmentation of partially-blurred images using wavelet transform

In the research a method for segmentation of partially-blurred images using the wavelet transformation, particularly coiflet of the order L=3 is presented. The entropy is used as a segmentation criterion based on wallet transformation. K-means method is used for image segmentation. Developed method was tested and has shown good results of his work; it correctly performs more than 82 % of pixels of image, and in many individual cases, more than 90 %.

Thermodynamic properties of solubility of 2-methyl-5-arylfuran-3-carboxylic acids in organic solvents

The temperature dependencies of both acids solubility in acetonitrile, dimethylketone, isopropanol, ethylacetate and benzene were investigated. The results were represented by Shredder’s equation according to which enthalpies, entropies and Gibbs energy of solubility at 298 K were determined. Fusion heats of the acids were determined using differential thermal analysis. In accordance with obtained values the enthalpies, entropies and Gibbs energy of mixing were calculated. The compensating effect of mixing was observed for al solvents with carboxy group.
