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.

For the process of renewal of the order (k 1, k 2), generalizing the acquainted simple and general processes of restoration in the theory of reliability, there has been proved convergence of the renewal quantity distribution at the t moment to the normal distribution.

The paper considers the algorithm of the continuous model (profile) correction. The initial data are the initial profile and the previous inquiry history. The PLSA (Probabilistic Latent Semantic Analysis) methodology is used in the algorithm. To achieve the object in view, the term temporary latent semantic space is introduced.

On the spaces H a the estimates are found for the norm of the error functional δ N[f ] of cubature formulas possessing the Haar d-property in the two-dimensional case.

Asymptotic properties of multidimensional nonparametric regression, synthesis of which is grounded on estimations of a probability density of Rosenblatt-Parzen, are explored. Their quantitative dependence on flavor of kernel function and features of initial statistical data is determined.

The paper analyzes the technologies of modern web programming, based on the use of JavaScript/AJAX/CSS/PHP. The functional capabilities of a number of popular web application frameworks are considered. The specifications of the developed web application for spatial metadata processing are discussed.

The authors offer a mathematical description of gas-liquid flow in micro channels of various geometry with the account of chemical reactions, friction and heat exchange and make a comparison of results of calculation of fluid flow in micro channels with the data which were already published. Gas-liquid flows in micro channels of complex geometry with chemical reactions and heat exchange are shown on an example of flow in micro channels of liquid monopropellant micro thruster. Results of calculations of processes of catalytic and thermal decomposition of a hydrazine, hydro- and gas flow in the distributive block, the catalytic reactor and a nozzle, heat exchange processes in the engine chamber, are presented.

The authors consider the capability of accuracy improvement of melting control at the electron beam welding process, due to optimal choice of scanning signal magnitude.

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.

At welding with direct and reverse polarity in carbon dioxide with the wires of 1.2 mm diameter at a current of 12 amps or more. Spraying at the minimal voltages is not observed.
