Modeling of partially regular microreliefs formed on the end faces of rotation bodies by a vibration method

The scheme of formation of a set of variants of grooves of partially regular microreliefs formed on the end faces of rotation bodies by a vibration method has been developed, and the conditions of their existence have been determined. Using a block approach, mathematical models of partially regular microreliefs have been constructed, which described a set of their variants, taking into account such characteristics as the shape of axial lines of continuous regular microroughness, type, and location of axial symmetry lines of grooves, and groove shape.

Some aspects of the individual methods of prevention of juvenile offenders

In the article the features of individual prevention of juvenile delinquency and method of implementation. The attention to specific principles, hierarchy management, methods of different levels of special prevention of juvenile delinquency. The expediency distinguish methods of studying juvenile offender in order to further the prevention of it, and immediately the individual methods of prevention. The article revealed the essence of appropriate methods. Recommendations for their productive implementation.

Розроблення методики оцінювання важливості характеристик стеганографічних алгоритмів

In this paper the problem of estimating the importance of each of the characteristics of steganographic algorithms is solved. The resulting estimates are used in the analysis of the existing algorithms for information embedding and multiobjective choice of the best algorithm. The technique allows providing an equally weighted algorithms estimation, and also considers the importance of coefficients of characteristics.
