The key to the mystery of the stone book

In datum research with the help of mathematical methods as heuristic cluster analysis, method of correlation galaxies and method of chi-squared for comparison nominal features was worked out the system of comparison the petroglyphs of elks and deer from Belomorye. The breaking the petroglyphs up according to the similarity between them with the revelation the groups of elks and deer was suggested. With the usage of achieved results the system “PIRS” was worked out. It is intended for specialists, who study the petroglyphs. In this system the search of similar depictions of the petroglyphs was organized on the basis on the neuron Hemming network.

New method for cold welding of parts by plastic deformation

Cold welding of parts with plastic deformation is used in cases when effects of high temperature, vibration and impulse loading are inadmissible. Researching the methods of presser welding it was established that not only the quality of the bridging but the thickness of the bridge in vulnerable cross-section has an influence on the strength of the weld. The method of increasing the strength of weld joint of work pieces made of aluminium alloys is proposed. Tests of a new method of welding electric tires and encapsulation of capsules are described. It was found out that the strength of joint increases twofold.

Sludge as a gift of nature - original method of the bio-utilisation

The problem of domestic waste has been one of the most urgent problems for mankind for a long time. The sludge of municipal cleaning structures is one of the sorts of waste products. I developed the design of the engineering plant and the shop for the practical utilization of the red California worm in sludge handling in municipal cleaning processes. After utilization, biohumus is generated which can be used as fertilizer for planting of trees in towns, in agriculture and so on, and so forth. Profit can therefore be made from the “waste” of municipal cleaning processes.
