We develop a photothermal technology to control optical heating of polymer and liquid crystal films through a refractory titanium nitride (TiN) metasurface. The metasurface represents an array of identical square-shaped ...

A prototype of a low-cost GNSS receiver assembled on base of the u-blox ZED-F9P module is described in the paper. The original low-cost GNSS receiver (OGNSS-R) allows made the parallel registration of 184 channels in the ...

This paper discusses the use of electro contact baking of steel powder on a bronze bushing. Its main design parameters are: taper angle of the matrix part - a, deg.; internal diameter of the matrix - D, mm; length of the ...

In this research considers the combustion of methane mixtures with hydrogen or propane-butane fuel as applied to water heating installation. The determination of conditions under which the considered mixtures have a ...

Titanium powders are widely used in selective laser melting and electron beam melting technologies to create medical implants. However, powders of a certain fractional composition are suitable for these purposes. A gradual ...

In this work, a new process of plasma-electrolyte sputtering under the action of ultrasonic vibration is proposed, which makes it possible to obtain a finely dispersed metal powder with an average particle diameter of about ...

A solid fuel combustion chamber of the Helmholtz-resonator-type is investigated. In previous works, the air supply tube and the combustion product outlet tube were open at the outlet. In this paper, we consider a device ...

The process of adjusting a gear broaching machine is considered, according to the angle of the cone of the depressions and the symmetry of the side profiles of the gear wheel. Standard adjustment methods do not allow ...

The gear broaching method, in contrast to the hobbing methods with hob cutters, belongs to the shaping copying methods. The result of the gear broaching is a gear profile that is geometrically different from the theoretical ...

The article presents the results of solving the scientific problem of ensuring folding, which is complex and includes the appointment of optimal tolerances, maximum deviations and landings in the design. The authors presented ...
