The SLM-process has been optimized for manufacturing of parts from Co-base alloy powder on the machine ПТК-ПС. The XRD analysis is researched and physic-mechanical properties of the samples made on optimum parameters of selective laser melting are defined.

The 21st century is a time of active introduction of elements of robotic technology in the life of the entire human society and geodesy in particular. Innovations in the development of modern geodetic instruments and their software increase productivity, technical skills, and accuracy. One of the developing areas has become the industry of 3D scanner shooting software.

A new technology for processing vegetative plants on large agricultural areas at night with a UAV is described. The use of an unmanned aerial vehicle as a mobile platform with a device attached to it for stimulating non-thermal intensity of vegetative plants with optical laser radiation at various stages of ontogenesis contributes to the development of plants at the initial stages of vegetation and, as a consequence, at later stages of growth, increasing their resistance to certain diseases and productivity., which allows at the stage of storage to significantly increase the safety of the crop without additional investment in the vegetable store.

The article discusses the possibility of using QR-code in the production complex of the center of technical competence of tool production, in the visualization of technical parameters of the tool, the recommended modes of material processing by the selected tool in the code encoding.

Relationships of cause and effect which are the cornerstone of the phenomenon of observability of area of hydrophysical indignations from an underwater moving object, including its exit to a sea surface when lighting the area in the thickness of water by a laser beam and radiation of the sea surface over an object with a radar station signal are described in the article. In the stationary marine environment the laser beam creates a backscattering signal of a fixed level. In the area of hydrodynamic indignations from an underwater moving object the signal of a backscattering of variable brightness to the relevant structure and level of indignations is seen. The similar phenomenon of a backscattering of the electromagnetic radiation of radar station that creates glare effects on the screen of radar station in a zone of an exit of hydrodynamic indignations is observed on a water surface. It is shown that these phenomenons have similar nature caused by the change of dimensional orientation of dipoles of molecules and liquid crystals clusters of water in the field of the hydrodynamic indignations accompanying the moving of an underwater object. Establishing of this characteristic, in case of its confirmation by test data, meets the requirements of qualification of opening.
