The most important task in the manufacture of concrete structures and products to provide the required quality of the front surface of the finished product. Currently, there are quite a number of ways to improve the quality of concrete products and structures surface. One of these ways is isolated unit of the underlying layer in reinforced concrete and concrete structures.

In recent decades, a trend of annually growth in the number of patients with defects of facial skull and cerebral cranium as a result of serious concomitant craniofacial injuries has been emerged. Clinical material is presented by 53 patients in the period of 1985-2008. A technology of fixation of perforated implants of clear titanium by titanium screws was used during reconstructive ...

Two-layer coating of the «thermodiffusion layer – PVD coating TiAlN» was obtained. Microhardness and tribological properties of the resulting two-layer coatings and the contribution of TiAlN coating in integrated micro-hardness of the surface on different substrates was investigated.

Results of comparison tests of the copper coverings created by galvanic sedimentation and the deformation cladding by the flexible tool (DCFT) are given. Delamination tests have shown that the plated coverings do not exfoliate from basis material even at breakdown of experimental samples while electroplated coatings exfoliated on 0,5 cycles of a bend. Tribotechnical tests have ...

There is no doubt that new pre-select gearbox will be the best of automatic transmissions in the near future. That why it is necessary to use innovative methods of diagnostics to avoid unexpectable expenses for repairs. Article gives an information about new method of diagnostics, which is based on computer diagnostics and parallel monitoring of gearbox work in dynamics on special stand.

In the thesis the shortcomings of the modern systems reduce the toxicity of diesel engines. The proposed method improve the performance parameters of a diesel engine using a gas fuel and a system for realization of this effect.

The report describes loosely coupled inertial-satellite navigation system for moving object. The system uses measurements of magnetometric sensor for correction of navigation information. Extended Kalman filter is used for processing the navigation data. The results of modeling the behavior of the system under various driving modes shows an increase in the accuracy of determination ...

This research is connected with the expansion of global satellite navigation systems application. All the experiments conducted were devoted to the development of the algorithm of obtaining the mobile objects orientation angles using satellite signals. For obtaining and processing of experimental data adaptive filters were used. The results obtained can be applied for solving a ...

In the paper authors compare additive manufacturing processes that use wire and processes that use metal powder. Also, there are new results of author’s investigates in Electron Beam Free Form Fabrication process.

This work describes a method and apparatus designed to combat AFS, whose operating principle is based on the temperature regulation in the well. Also, the paper presents a demonstration of physical and mathematical formulas for the software to implement the full automation in the management of the developed device.
