In this paper we present the calculation method of the gliding radial bearing similar to the circular one in the presence of unevenness on the barrel surface. As a result, we suggest the construction of a non-circular bearing which has twice as high bearing capacity in comparison with the circular one. Impact of barre…
Estimation criteria of the personnel by means of marking their basic properties influencing reliability are considered. On the basis of the selected properties indicators characterizing each of them according to a special technique are worked. An attempt to apply formal logic for shaping and using properties and quali…
An improved method for constructing and training single-layered spiking neural networks is preposed. The method allows to apply single-layered spiking neural networks that encode each data dimension by one neuron of the input layer for the recognition of complex and overlapping clusters with procedure of unsupervised…
The possibility to decrease the computational expenditures when solving the boundary problems at the expense of the rational representation of the Green's functions is shown in the article. The capability of more optimal algebralization of the mathematical relations is illustrated on the example of solving the problem…
A number of successful theoretical models of hardness have been developed recently. A thermodynamic model of hardness, which supposes the intrinsic character of correlation between hardness and thermodynamic properties of solids, allows one to predict hardness of known or even hypothetical solids from the data on Gibb…
A conceptual model of the computer-aided decision support system in an emergency situation at the machine-building plant is discussed in the article.
In the light of the propositions on the modernization and technological development of the national economy made by President D.A. Medvedev, the directions of constant and urgent necessity of carrying out this work taking into account the branches providing accumulation and replenishment of the capital are proved. On…
Substantiation and definition of the new concept ‘geopedagogics’ due to the global processes in the modern world are given in the article. The problem of education evolution and a new educational model formation is put.
Electric circuit of analog and digital units of fine positioning system of machine parts using the programmable microcontroller is presented. The instrumentation electric drive controlled with PIC16F877A microcontroller is designed. The device is equipped with the interpolation unit, the digital display and the matrix…
Family records of several Cossack families demonstrate that market economic thinking was typical for Cossacks even in the prereform period. Thinking, behavior, moral and ethical arrangement of life among Don landowners of all categories were not only close to the traditional Russian serfdom type, but also show that th…
Solution of the problem of acceleration and increase of measurement tools choice objectivity with help of database creation on ACCESS basis is considered. As a result the opportunity of a wide review of measurement tools of the set measured size, their choice according to the required metrological and technical charac…
We report on a novel type of Bi-doped crystal that exhibits ultrabroadband photoluminescence in the near infrared (NIR). Emission centers can be generated and degenerated reversibly by annealing the material in CO atmosphere and air, respectively, indicating that emission is related to the presence of Bi-species in lo…
In this paper, a new sandwich with an orthogrid stiffened shape memory polymer (SMP) based syntactic foam core was proposed, fabricated, programmed, impacted, healed (sealed), and compression tested, for the purposes of healing impact damage repeatedly and almost autonomously. Two prestrain levels (3% and 20%), two im…
Phase change memory (PCM) could potentially achieve high density with large, 3Dstacked crosspoint arrays, but not without a BEOL-friendly access device (AD) that can provide high current densities and large ON/OFF ratios. We demonstrate a novel AD based on Cu-ion motion in novel Cu-containing Mixed Ionic Electronic Co…
The nonbiodegradable and nonrenewable nature of plastic packaging has led to a renewed interest in packaging materials based on bio-nanocomposites (biopolymer matrix reinforced with nanoparticles such as layered silicates). Bio-nanocomposite films based on soy protein isolate (SPI) and modified montmorillonite (MMT) w…
Composite magnetic nanoparticles (MNPs) consisting of an MNP core and drug loaded polymer shell can increase the efficacy of cancer therapy by overcoming several limitations of conventional hyperthermia and chemotherapy. Multimodal therapy consisting of simultaneous hyperthermia and chemotherapy can increase therapeut…
We consider a continuum model describing the dynamic behavior of nematic liquid crystal elastomers (LCEs) and implement a numerical scheme to solve the governing equations. In the model, the Helmholtz free energy and Rayleigh dissipation are used, within a Lagrangian framework, to obtain the equations of motion. The f…
Magnetic nanowires are a good platform to study fundamental processes in Magnetism and have many attractive applications in recording such as perpendicular storage and in spintronics such as non-volatile magnetic memory devices (MRAM) and magnetic logic devices. In this work, nanowires are used to study magnetization…
Understanding of charge transport mechanisms in nanoscale structures is essential for the development of molecular electronic devices. Charge transport through 1D molecular systems connected between two contacts is influenced by several parameters such as the electronic structure of the molecule and the presence of di…
Defect characterization in 1.2 MeV Ar8+ irradiated polycrystalline ZnO has been carried out by x-ray diffraction (XRD), scanning electron microscopy (SEM) along with electrical resistivity, and photoluminescence (PL) measurements at room temperature (RT). Interestingly, irradiation with the initial fluence (1×1015 ion…
