A CLASSIFICATION ALGORITHM BASED ON ENSEMBLES OF NONPARAMETRIC MODELS
Abstract
The paper deals with a classification strategy which utilises nonparametric modeling of a decision rule in a case of large feature vector length and large sample volume. An algorithm of collective assessment of k-nearest neighbors is proposed, which significantly reduces the computational cost. The work of algorithm is demonstrated on one application problem.

SPIN AND CHARGE CORRELATIONS OF THE ELECTRONS IN THE DIMER WITH DEGENERATE ORBITALS AND ELECTRON OCCUPATION n = 1,5
Abstract
The spin-spin correlation functions in the dilatational and transverse components of the spin, the correlators of density of electrons, located on different orbitals in the Hubbard model in two limiting cases are calculated by the method of exact diagonalization; the Coulomb repulsion on the node point is comparable to the width of the band (U ≈ W) and significantly lower (U < W) as compared with degenerate orbitals and the occupation number n = 1,5 are calculated by the method of exact diagonalization. A non-collinear spin arrangement and the temperature dependence of the spin and charge correlations of electrons are revealed.

ELEMENTS OF A NUMERICAL PROBABILISTIC ANALYSIS
Abstract
In this paper the authors define the notion of a numerical probabilistic analysis. Its elements are considered in terms of theories and their applicability in practice. The authors explore the notion of probabilistic extensions, present overview of the approaches to the calculation of functions of random arguments and operations on them, and provide with examples of elements of the analysis in the practice of solving economic problems. It is shown that this approach can be considered in some cases, as a real alternative to the Monte Carlo method that can significantly improve the calculation accuracy and to reduce their volume.

AUTOMATION OF PROCESS OF PRODUCTION OF MOLDS FOR MANUFACTURE OF LIP SEALS
Abstract
Lip seals are used to ensure the tightness of the executive units of hydraulic systems. An important role for improving tightness is played by form of distribution diagrams of contact stresses, which excludes or reduces possibility of hydrodynamic pressure, as well as providing a return fluid leak in the sealing chamber. Currently used methods of production of contact seals, with the help of injection molds are based on the sizing of the GOST 14896-84 on the seals and the mold. However, the dimensions given in this document often do not guarantee the specified resource because it does not take into account the operating conditions. The paper describes a method of automation of process of production of molds for manufacture of lip seals, through the construction of parametric models of contact-type lip seals, which include the optimization of their design parameters and shape, according to the specific set conditions of subsequent operation, to provide a given guaranteed working capacity resource.
