Refitting of flint materials is in recent times a standard method of dealing with flint materials. Among the archaeologists, however, there is a feeling of insufficiency and disproportion between the time needed for conjoining the blocks and the scientific effects coming out of them. Above all, there is at present no method for comparing different effects with other conjoined blocks. Regardless it comes from one archaeological site or whether are from different ages or territorially distant from each other. The paper presents a proposition of a new method for the analysis of flint refittings. The idea of research is to determine the relationships between the various detached pieces. The results are presented in a graph which we can further analyze and compare with others. The process itself is similar to the simplification of functions invented by Newton and Gauss, which is why the name of the method: refitting calculus.Refitting of flint materials is in recent times a standard method of dealing with flint materials.

Multilayered antifriction nanostraction covering for lubrication in the tribocoupling

In article principles of creation of a new way of the lubrication a wheel-rail tribosystem by drawing on a lateral side of a rail head of a multilayered antifriction nanostructurial covering possessing property of blocking negative segregation phenomena in metals of a wheel and a rail are considered

Simulation of the coordination number of random sphere packing

Given article presents a generalized equation for calculating the average coordination number from the density of a random sphere packing, supplemented by a dependence on the threshold value of the interparticle distance in two- and three-dimensional spaces. It is shown that the calculation of the average coordination numbers according to the proposed equation gives an unambiguous correspondence between the simulated, calculated and experimental data for threshold values of more than 1.02 particle diameters. An explanation of the weak dependence of the average coordinate number on the packing density for small threshold values of the interparticle distance is given in this wor

Mathematical model of coordination number of spherical packing

The article considers a mathematical model of the coordination number, which allows obtaining an equation for multi component spherical packing in the entire range of its change. The resulting model can be used in both 2-d and 3-d spaces. The concept of the coordination index is introduced as a function of the inter-particle distance related to a single particle located near the central particle. The model provides unambiguous compliance between the simulated and calculated data on the coordination numbers of the spherical packin

Symbolic-numeric approach for solving linear differential equations of the fourth order

This paper presents a symbolic-numeric approach for solving linear differential equations of the fourth order in the form of generalized power series. The working program allows to find solutions to differential equations of the fourth order in the form of power series, generally, of any order, but is limited by capabilities of a given computer. Some examples of solving differential equations of the fourth order are presented, which show the efficiency of the developed progra

Computer modelling of material objects’ structure. Part III. Clustering of nucleon systems

The structure of light atomic nuclei, such as hydrogen, helium and lithium nuclides, was studied based on the cluster approach. Atomic nuclei are formed as systems consisting of free and bound lovetons, as well as neutron electrons and electron-positron pairs. The work focuses on the mass of the atomic nucleus and its binding energy as the main basic characteristic

Computer modelling of material objects’ structure : Part I. Space-time

Present paper considers a structure model of discrete space-time, the properties of which are determined by the substrate. As a substrate a 2-dimensional plane under no matter is chosen, the surfaces of which are space and anti-space. A new concept called spacetron, considered as a spatial element of the substrate, which is the basis for the subsequent formation of 4-dimensional space-time, is propose
