Issues of high-quality and reliable water supply are closely related to automation and management of engineering systems for stormwater and wastewater treatment. Options for managing continuous technological processes formulate different goals. Different control algorithms correspond to different variants, and, consequently, different methods of algorithmic support systems and control system structures. The expediency of dividing the general task of sorption purification control into several subtasks of a smaller dimension is shown where the control system acquires a hierarchical structure: at the lower level, the task of separate adsorption tanks controlling is solved, at the upper level, the task of controlling the entire purification plant as a whole. The criterion of operational management is provided. The scheme of adaptive control of continuous sorption purification systems is given.

One of the main conditions for ensuring information security is to prevent the spread of false and intentionally distorted information. Filtering the content of Internet information resources can serve as a solution to this problem. Recently, an approach using methods and mathematical models of artificial intelligence has been increasingly considered for the analysis and classification of disseminated data. The use of neural networks allows you to automate the process of processing a large array of information and connect a person only at the decision-making stage. The paper focuses on the learning process of a neural network. Various learning algorithms are considered: stochastic gradient descent, Adagrad, RMSProp, Adam, Adama and Nadam.

This work investigated the influence of the type of vertical switching on the level of thermomechanical stresses and temperature deformation in a three-dimensional microassembly. Three microassembly models with the most common types of vertical connections were considered: solder balls in the package holes, metallized holes in the package, and end-switching tracks. For each of the three models, the effect of the sealing compound parameters on the thermomechanical load was additionally investigated.

A huge part of the territory of Russia is located in the permafrost zone. Ensuring the reliability of pipeline systems transporting hydrocarbons in these conditions requires an integrated approach that takes into account the structure of the soil, the peculiarities of construction methods, the temperature characteristics of the soil and the transported products. Evaluation of the interaction of the pipeline with frozen ground is an important factor in the design. And the justification of the choice of an engineering solution for the construction of pipeline systems, ensuring their stable position, is one of the tasks of our research. The gas pipeline at the Kamennomysskoye-Sea field is considered as an object of research. A brief description of the features of the construction area is given. A strength calculation was performed, on the basis of which the design parameters of the pipeline were adopted. A comparative analysis of the ways of laying the pipeline was carried out, which made it possible to identify the most satisfying conditions of reliability and economic efficiency.

The results of studies of the effect of mineral additives of natural and man-made origin on some properties of fine-aggregate concrete with the introduction of a mineral additive from 10 to 25% of the cement weight instead of either a part of cement with an increase in the value of W/ C, or a part of sand with a constant value of the value of W / C are presented. A slight, up to 3%, change in the average density of concrete was revealed. A decrease in the E-modulus from 4 to 14% was recorded when replacing a part of cement, while an increase in the flexural strength, depending on the dosage, was up to 26% (marshallite) and 6% (chemical water treatment sludge), and a decrease in the compressive strength was from 10 to 22%. When replacing part of the sand, an increase of up to 10% of the E-modulus, the flexural strength from 19 to 38% (marshallite) and up to 11% (chemical water treatment sludge) was recorded. The increase in the compressive strength, depending on the type and dosage of the additive, ranged from 8 to 20%. No significant effect of additives on the porosity of cement stone was revealed.

The seismic activity of the zones through which the pipelines are laid has always caused serious concern. The analysis of emergency situations on pipeline systems caused by an earthquake revealed factors affecting their stability: longitudinal and transverse displacement of the soil, the effect of soil liquefaction, faults resulting in open cracks and shear deformations. To prevent damage to pipelines during seismic impact, it is necessary to take into account the nature of the impact on the pipeline structure, the required level of safety for this seismic impact. Currently, special attention is paid to structural solutions and materials from which pipelines are made. The conducted studies allow us to form an approach to assessing the operability of polyethylene and steel pipelines in earthquake-prone areas, and on the basis of a comparative analysis of their stability, to make recommendations on the use of pipelines under specified conditions.
