The problem of grain harvesting unit productivity as MMS is dealt with the method of rational labor regime introduction. The plot of productivity coefficient change are made up by different operating conditions of personnel. The plots consider the influence of man factor on changing of the grain harvesting unit produc…
In present article the design procedure and modeling of the stationary and almost stationary magnetic field, based on transformation of a vertical magnetic field to a potential of sources is stated. In result, electric currents are replaced with magnetic charges, and the equations for vectors of a field are replaced w…
The functional copolymers, having a combination of rigid/flexible linkages and an ability of complex-formation with interlayered surface of organo-silicate, and their nanocomposites have been synthesized by interlamellar complex-radical (co)terpolymerization of intercalated monomer complexes of maleic anhydride (MA) a…
In rubber investigation, many strain energy models have been proposed for the hyperelastic behavior. One of earlier models, that of Gent-Thomas (1958), based on theoretical and experimental considerations, has been forsaken in the rubber modeling literature, because of difficulties in establishing its domain of validi…
There are proposed some algorithms of digital signal processing specific for audio pieces recorded in the form of wav-files. A concept of auto correlation function is introduced, and there are indicated some objective parameters which characterizing the signals of such a type. Some practical aspects of possible aspect…
Results of experimental determination of the processes of development fatigue crack in tube steel with structure of the natural ferrit-martensitic composite material (NFMC) are presented. It is shown that achievement of constructive heavy-duty is caused by special mechanism of the spreading crack in steel with structu…
In paper the equations of a nonholonomic constraint of the second order which exhibits the properties at turning on lenix a flexible drive in a drive of a thrasher of the grain combine are gained. For a justification of type of a nonholonomic constraint the oscillogram of real processes of acceleration of a thrasher i…
The adequate mathematical model of the process of the functioning of aerial - latticed grain cleaning machine with mutitier lattice - like moduli has been constructeol.
An experimental research of fractional technologies of a food grain cleaning is executed and theirs principal results are given. Key words: fractional technology, experimental research, food grain, cleaning, experimental cleaning grain unit.
Application of method АКАР («Analytical designing of the aggregated regulators on the set invariant varieties») sinergetics theories of management for synthesis of laws of management by spatially-nenvariantnym nonlinear distributed object of management is considered. The object of management chooses water horizont the…
In article there are brought the cardinal principles of creation of the spindle node condition monitoring system of turning unit based on fuzzy-logic. There will be analyzed different factors, influencing upon accuracy of the processing product on machine tool with CNC and are chose the main influence. The fuzzy-logic…
The problem of mathematical description of the moving process of a labour body in the soil with allowance for fastening elasticity is being soloed now. The analogy with the problems of aero and hidroelasticity is being established now. A model in the form of Coshy has been obtained; drag force depends on elastic shift.
An efficient analytical method of studying multidimensional systems with a purpose of extracting controllable sub-systems of the Jordan forms is presented. A mathematical model and algorithms for estimation of the presence of Jordan signs in controllable multidimensional systems on the basis of which a decomposition o…
We have performed ab initio LDA calculations of the electronic structure of newly discovered prototype high-temperature superconductors AFe 2 As 2 (A = Ba, Sr) and compared it with the previously calculated electronic spectra of ReOFeAs (Re = La, Ce, Pr, Nd, Sm). In all cases, we obtain almost identical densities of s…
Abstract This paper describes the electrochemical performance of carbon onions as electrode materials in electrical double layer capacitors with water electrolytes. Onion‐like carbon (OLC) species were produced by vacuum annealing of detonation nanodiamonds (NDs) powder at 1170–2170 K. The material capability of the c…
Plastic deformation at constant rate and low temperatures starting with 20–30K, as a rule, occurs in the form of oscillations of the deforming stress (serrated deformation). Low-temperature serrated deformation (LTSD) appears under special conditions where deformation occurs as a result of the specific conditions of d…
In recent years, medicinal chemists have begun to realize that dendrimers may be a keystone in the future of medicine. The field of oncology will soon be revolutionized by novel strategies for diagnosis and therapy employing dendrimer-based nanodevices. In the near future, cancer diagnosis via MRI will be improved by…
The location of the energy levels of rare-earth (RE) elements in the energy band diagram of BaF2 and CdF2 crystals is determined. The role of RE 3+ and RE 2+ ions in the capture of charge carriers, luminescence, and the formation of radiation defects is evaluated. It is shown that the substantial difference in the lum…
The parameters of many-body potentials for Co, Nb and Zr metals, based on the embedded-atom method, have been systematically derived. The analytical potential scheme allows us to reproduce correctly the cohesive energies and structural properties of the pure metals and selected alloys making use of a small set of para…
Transparent and stable composites of calcium carbonate and an acidic macromolecule are obtained at mild conditions. The nanosegregated structure is formed in the amorphous composite materials in the bulk and thin-film states. The transparent, stable, and crack-free thin films might be beneficial for coating of materia…
