Abstract
The smoothing process is considered. Depending on the smoother digging into the work surface, the eq uation in variations about the smoothi ng balance point varies. For providing the rational setting of the process, the method based on the vibroacoustic emission signal analysis, in which the gradient parameters of the mechani cal - and physical properties of the surface coating are represented, i s offered.

Abstract
The possibilities of the modern software package of block - modular simulation to the transient simulation tasks in the gas stream in the natural gas transportation area are considered. An approach to modeling in vec tor format the spatiall y distributed cell model object generated on the special nonlinear basis is offered. This permits to solve the problems on diagnosis and flow control in the transient processes by macro - cellular modeling of its mass and kinetic energy balance. The adequacy of the starting and ending state of the cell model is provided by the calculation of the reference - parameter vector that characterizes the steady - state flow, and by comparing it with these states.

Abstract
It is shown that the intensive threshing mechanism, containing the drum with smooth rasp bars an d the concave with a convex inlet and canting bars with flanges (_/ - shaped bars) without rods throughout the remaining exte nsion, may become more effective with fuller allowance for mechanical - and - physical properties of the threshed m aterial. The changeabi lity of the classical space geometry between rasp bars under the resistance reduction of the concave is proved. The laboratory tests and test - use of the intensive threshing mechanism are resulted.

Abstract
The theoretical research on the noise emission process under the ball - and - rod hardening of the bar - and plane - type parts is considered. The analytic dependences of the produced noise spectra are obtained. That is th e basis for making the engineering de cisions on the bringing the acoustic characteristics to the sanitary norms at the design stage of such processes.

Abstract
The problem on the design values optimal choice of the grain combine drive elements, when these elem ents are implemented through the V - belt and hydraulic transmissions, is set and solv ed. For this purpose the minimax pri nciple, implemented through the method of the optimal design of the state - space dynamic system parameters under the alternating loads, is used. The author’s previously generated theoretical model of the combine d rive dyn amic system with the nonlinear nonholonomic first - order constraint is used to form the state space.

Abstract
The heuristic potential of the ‘sociocode’ concept in the analysis of the social essence and histori cal typology is considered. The qualitative difference typology of the cultural oases provides the basis f or solving the problem of ethnocultural contradictions. The thesis on the incompatibility of sociocodes is regarded as a meani ngful principal for the comprehension of the current civilizational conflict prospects. The incompatibility of socio codes is cause d by different ways and rates of the new knowledge acquisition and utilization, and of the social process es renewal. The foundations for conceptualizing ‘knowledge society’ are revealed.
