Video surveillance systems are the most high-tech components of the security system at any facility, which are firmly integrated into our lives as elements of ensuring its safety. The most effective ways for self-service stores are to install video surveillance systems in the sales area, utility rooms and warehouses, install anti-theft frames and tags on the goods. The control ...

The article examines polygonal hole machining using a Watts drill and shows how an appropriate movement toolpath for the cutting tool is developed, using the Mathcad software.

The paper presents options for upgrading a roller press in terms of equipping it with an active system for stabilizing the thermal conditions of the rollers, as well as by using elastic membranes in the cells of the rollers. The efficiency of using a roller press is ensured by increasing the service life of the roller structure and the stability of the process of pressing bulk material.

In this study, grinding of alumina, zirconia and titanium dioxide coatings sprayed by air-plasma method was investigated theoretically and experimentally.

The microstructure and phase composition of the material based on impact diamonds obtained by hot dynamic pressing have been investigated.

An approach to assessment of vehicle driver’s vigilance during professional activity is proposed. The approach is based on monitoring of the vehicle, driver, and environment states; and involves detecting the unintentional deviation from the driving lane, unsafe distance from the vehicle ahead, potential collision with a pedestrian in front of the vehicle, and speed limit signs ...

Requirements for selection of materials for diffusion barriers of PVD-coatings are formulated. The problem of TiN coating using as barrier sublayers is studied in this paper. It was shown that TiN coatings from 2 to 4 mi-crometers of thickness has a dense structure and satisfactory adhesive strength as to base and to protective layer. But they content structural components with ...

The spectra of infrared radiation separation by plasmonic dielectric/metal/dielectric structures were calculated using the finite difference method in the time domain. It was found that modification of the dielectric/metal/dielectric structure design can affect the type and magnitude of conductivity in the 8–13 μm range.

In recent years, virtual reality (VR) has become an important tool in various industries, including manufacturing and education. It provides an opportunity to visualize and test concepts and prototypes before they are physically built in production and to practice the necessary skills in training. In this article we will consider the possibility of using virtual reality for ...

The article focused on the investigation of the effect of laser pulses parameters on the removal intensity of organic-based layers from some steel surfaces. A series of experiments was carried out and it was found that two of the input parameters that most evidently influence the intensity of the laser cleaning process are the duty cycle and the pulse duration of laser irradiation.
