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 of these multidimensional systems into Jordan sub-systems has been built.

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 monitoring system and experimental checking data of the result of the designed system functioning will be presented.

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 with the equation for scalar function.

In this paper given results of comparative experiments on research of correcting ability of two Reed-Muller codes likelihood decoders (Sidel'nikov-Pershakov decoder and Loidreau-Sakkour decoder) are presented. For reception of experimental results the program imitating model of the digital data link is realized.

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 aspects of possible classification of various audio pieces are studied.

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 Central site of the Kislovodsk deposit of mineral waters.

The problem of mathematical modelling of stratified blood current in a blood vessel has been soled in the paper on the basis of a model of separated current of two inmixed liquids in a narrowing conic tube. The influence of viscidity relations of strata on the types of speed distribution and relative expenses nave been evaluated.

In the article the theoretical aspects of the functional scheme's construction and the groundwork of the intellectual systems of the decision-making support are scrutinized. They are discovered by means of the complex application of the mathematical methods at the solving of the problems in the various spheres of an activity.

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.

The structure and interrelations of subsystems of expert system for of a combine's harvester technological adjustment is considered. expert system's operating modes and various aspects of representation of knowledge are described.

To cite data technique and results of research of speed of movement and the sizes of portions of grain weight on the basis of records of oscillograms of efforts of compression moving in a gap of a thresher of a grain stream.

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 productivity as MMS.

The analysis of agricultural machines as objects of hydrofication is lead. The description of the device and functioning one-machine drive is given, the mathematical model, dynamics of a multiline hydraulic drive is resulted.

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.

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 is used It is displayed, that the accepted schematization of real process of turning on lenix-transmissions incidentally differs from it. Three phases of operation lenix-transmissions are selected at turning on and for each phase constraint equations are gained. The generalised constraint equation merges all three phases of operation and is a nonlinear nonholonomic constraint of the second order. Outputs contain assay values of the gained differential equation on integrability and confirm, that connection is nonlinear to nonholonomic the second order.

The adequate mathematical model of the process of the functioning of aerial - latticed grain cleaning machine with mutitier lattice - like moduli has been constructeol.

A withdrawa l of a mathematica l mode l of stress-strain state curved beam changing sections and curvature in polar coordinates, allowing the decision through power and logarithmic functions.

In article the approach to the analysis of an intense condition of a design based on division of stress on stress connected with the structural stress, a configuration of a design as a whole and with microgeometry in front of the toe, the notch stress is considered. Results of increase of fatigue durability pipe connections are submitted by change of their constructive form based on the given approach.

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 structure of NFMC.
