Abstract

A tamping – an effective way of soil compaction. At a tamping the ground is dabed at the expense of a tool impact energy. Hinged ground sealing the equipment to excavators hydrostamps on the basis of hydraulic impact devices are perspectiv. Data about ground sealing equipment on the basis of hydraulic impact devices are resulted. Power indicators (energy, capacity of individual blow) hydropneumatic impact devices depend on speed mobile part and its such design data, as weight, course size mobile part, pressure of gymnastics of gas of the pneumoaccumulator. Dependences of mass of loose ports and an impact energy from width of a dabed surface soil and contact voltages on a ground surface are presented.

Abstract

For a dynamical system of a plane pendulum with vibration damping, describing the oscillations of the load of a bridge crane on a flexible cable suspension in a separate vertical plane, it is proposed to use a sinusoidal function with an offset to determine the time dependence of the deviation angle of the cargo rope from the gravitational vertical. Varying the acceleration time with a change in the rope deflection angle according to the proposed analytical dependence allows to achieve different speeds of cargo movement in the absence of cargo oscillation mode, as well as various maximum acceleration of the suspension point. An analytical solution is obtained for the problem of suppressing residual oscillations of the bridge crane load that arise after the full acceleration or deceleration of the suspension point of the load on the freight trolley. To derive the dependencies, a method is used to recalculate known analytical dependencies of the angle of deviation of the load line of a bridge crane from the gravitational vertical, depending on the acceleration, speed, and displacement of the suspension point of the load.

Abstract

As a result of the stand experimental studies on the digging of cohesive soils under hydrostatic pressure by the modern flat blade having a longitudinal gap near the cutting edge, a significant reduction of resistance to digging in comparison with digging in the same conditions the conventional flat blade was found. Provided that such reduction of the soil digging resistance is due to the penetration of the water through the longitudinal gap at the front face of the blade, which substantially reduces the coefficient of friction between the front face of the blade and a soil layer. The experimental studies conducted on the stand of physical modeling for study the process of digging the soil under hydrostatic pressure. The depth of immersion of the working body in the water was simulated by creation of a corresponding hydrostatic pressure in the hermetic chamber of the stand.

Abstract

The methodology of modeling pressure-free pressure filtration of water in urban construction is considered. A feature of this process is the presence of a creeping boundary of the free surface of water in a fractured porous medium if real nonstationary flows are considered as a function of time. The simplest one-dimensional case of pressure-free pressure filtration of water is considered. The hypothesis of the theory of filtration is stated, which allows to bring it to a new level of ideas about the motion of water in fractured-porous media with pressure-free flow. In contrast to the traditional point of view, the pressure for non-stationary filtration on the free surface of the water surface leaving the waterproof roof remains for some time in a state of vacuum, that is, below atmospheric. The author’s method of spreadsheets is proposed as a modeling tool. The motion of the creeping boundary is suggested to be realized using a conditional programming operator. The directions of the further development of the proposed methodology are indicated.

Abstract

In this article the question of increase in accuracy of transformation of three-coordinate sensors of vector physical quantities due to their design. Сonstructive errors, characteristic of threecoordinate sensors, are analysed. The analysis was applied to accuracy overall sensitivity of the sensor with three coordinates, and errors caused by the deviation of the axes sensor from orthogonal. It is shown that the error of the overall sensor sensitivity can be reduced to the desired minimum by calibrating the sensor for each coordinate, and the error due to non-orthogonality of the coordinate axes can be significant and reach a few percent (1.75%/deg). To reduce this error must be strict adherence to the orthogonality of the coordinate axes of the sensor.

Abstract

This work considers comparison of two images (original and target) that represent curves correspondingly shaped of set of points in two-dimensional space. The problem can be solved by finding the initial image of diffeomorphism that would allow to overlap matching points of deformable image with template’s points. Solution to the problem is based on the method of constructing a minimized functionality, which characterizes evolution process of the diffeomorphic transformation of the image from initial to the final one and “penalty charge” for the deviation of the image path from the required trajectory. An algorithm for solving the diffeomorphic transformation equation is developed on the basis of the gradient descent method. The considered problem of comparing two images can be used for constructing optimal metamorphosis of images, when there is no exact correspondence between the target image and the final image of the diffeomorphism. The designed algorithms can be used through a biometrical system, in images and subjects classification systems, machine vision systems, images and patterns recognition, tracking systems.

The methodology of the study of the relationship between culture and institutions in economic processes is proposed. Cultural-value system as a special component of the economic reality, contributing to the formation of the institutional shell is interpreted. Cultural values and institutional structuring of the economy acts as a compromise of interacting, heterogeneous entities at different levels are show. The relevance and increasing importance of the realization of ethical-oriented approach in the formation of institutional practices and the solution of strategical problems are justified.
