An increase in the extraction of resources is accompanied by their losses and dilution of ores due to the technogenic impact on ore-bearing massifs. The possibility of preserving the earth’s surface is provided by technologies with filling technological voids with hardening mixtures based on leach tailings, the insufficient activity of which is increased by processing in disintegrators under the influence of high energy. Experimental proof of the possibility of controlling the state of the hardening mixture was obtained in the course of many years of use of the disintegrator as part of the filling complex. The possibility of replacing cement with activated tailings has been proven not only as inert fillers but also as binders, which makes it possible to replace commercial cement with cheaper production of commercial products. Utilization of metals from enrichment tailings of various types of minerals allows the use of secondary tailings without restrictions on sanitary requirements. The combined effect of mechanical and chemical energies allows waste-free disposal of enrichment tailings and creates, in essence, a new base of metal raw materials to meet the needs of industry.

At present, a large number of developments in the field of neural networks are being carried out. All of the researchers are trying to use in their solutions and software products the algorithms of neural networks for maximum and automation without a clue of understanding they work. This circumstance can lead to erroneous data. The article is intended to consider the principles of the operation of neural networks in automated systems.

The authors examine dynamic and metrological characteristics of a vortex-acoustic flowmeter, a classification, a brief description, and the operation principle of widely used flowmeters. They present the results of research and exploitation of vortex-acoustic and electromagnetic flowmeters within the calibration interval (CI), obtained on an automated laboratory research test bench. The authors give some practical advice on choice of devices for flow metering based on the procedure of metrological reliability.

The operating system is the most important software component of any computer, and therefore, the security of the enterprise information system as a whole depends on the level of implementation of the security policy in a single operating system. In general, Linux operating systems (OS) cannot be considered as a ready-to-use security system. There are many recommendations on improving Linux security, but the authors of these recommendations do not guarantee that their recommendations are sufficient to achieve the required level of system security. This study attempts to systematize available methods for increasing the level of security of application software for Linux-like OSs operating as part of control systems at nuclear power facilities. The required level of security of the entire system can be achieved at the application software level.
