ELEMENTAL ESTIMATION OF OPERATORS’ PSYCHOPHYSIOLOGICAL STATE IN MAN-MACHINE CONTROLE SYSTEMS
Pupkov K.A.
Abstract
A problems of operators’ psychophysiological parameters estimation in man-machine systems is considered. To estimate the psychophysiological parameters it is proposed to use a pure time delay of operator and motor activity delay. It is show that integral delay may be effective integral estimation for man - operator state and its psychophysiological parameters.

THE KINEMATIC MODEL OF LINK MOBILITY FREQUENCY- CONTROLLED ELECTRIC DRIVE OF THE MANIPULATION ROBOT
Shraim A., Vnukov A.A.
Abstract
The article considers the kinematics of the level of mobility of the manipulator with an electromechanical transducer, the mathematical model and the design scheme of the two-mass model of mobility managers of the industrial robot with two rotating inertia-communicable elements boundby the elastic element. Mathematical relationships allow the regulator to take into account the angular speed of rotation of the asynchronous engine on the current site of the braking, stopping accuracy actuator transients develop a model of a real object, represented in the form of a two-mass mathematical model. The equations of the two-mass mathematical model can be used for a simplified version of the simulation, when the two-mass model is reduced to an equivalent one-mass model for mathematical modeling of the dynamic braking mode variable frequency drive manipulation robot. The received equations are used to model the possibility of operation of a variable frequency-controlled induction motor without overheating the windings.

THE RESULTS OF THE U/PB DATING OF DETRITAL ZIRCONS FROM THE PRECAMBRIAN AND PALEOZOIC SANDSTONES OF THE WESTERN PART OF BASHKIR UPLIFTS (THE SOUTHERN URALS)
Pyzhova E.S.
Abstract
There are the results of U-Pb dating of detrital zircons from the sandstones of the Bashkir uplift of the Southern Urals and the analysis of U-Pb-isotopic ages of detrital zircons from the six stratigraphic levels of the Riphean-Paleozoic section in the region.It is shown that in the long history of accumulation sedimentary strata of the Bashkir uplift may be allocated a special time interval. This interval is separated from the rest of the history of accumulation of sedimentary by boundaries of abrupt change in the composition of debris entering the sedimentary basins. There is a very great similarity of the spectra ages of detrital zircons from rocks of this range - the Late Early Cambrian lithic - and Ordovician quartzose sandstone. The proposed interpretation of the destruction Vend-Early Cambrian sedimentary strata, transport and accumulation of recycled quartz clastic material resulted in the formation ordovician essentially quartz sandstones.

CRITERIA FOR DISTINGUISHING RESERVOIRS OF HYDROCARBONS DEPOSITS OF PUR-TAZ PETROLEUM REGION (AREA)
Zubkova E.V., Myursep A.G.
Abstract
A distinctive lithology feature of productive strata of hydrocarbon deposits is zeolitization sandy layers. High capacity of zeolites to adsorb water molecules affects the basic physical properties of the reservoir, such as density, electrical resistivity, and natural radioactivity. Zeolitization of reservoirs are attributed mainly to the layers of BT.

GLASSFIBER REINFROCED CONCRETE
Al-Habeeb A.H., Abass A.A.
Abstract
Plain concrete possess very low tensile strength, limited ductility and little resistance to cracking. Internal micro cracks are inherently present in concrete and its poor tensile strength is due to propagation of such micro cracks. Fibres when added in certain percentage in the concrete improve the strain properties well as crack resistance, ductility, as flexure strength and toughness. Mainly the studies and research in fiber reinforced concrete has been devoted to steel fibers. In recent times, glass fibres have also become available, which are free from corrosion problem associated with steel fibres. The present paper outlines the experimental investigation conducts on the use of glass fibres with structural concrete.
