The paper focuses on energy efficient reconstruction of construction systems by means of their upward extension using modular spatial structures. It is further noted that the existing contradictory definition of the term “modular structures” necessitates classifying modular structural elements by spatial dimension, type and size, weight, degree of prefabrication, constructability and environmental safety. A list of the world’s leading manufacturers is provided featuring modular spatial structures to be used in the construction of new buildings and reconstruction of existing buildings. Also, the paper underlines the importance of using added stories in making modular roof structures of lightweight metallic structures (LMS) and lightweight thin-wall steel structures (LTSS) and provides an overview of the main types of modules, pointing out the key benefits of modular structures.

The important function of the automatic process control system is the ability to forecast and control the quality of a product. The implementation of these functions can be done by using formal models that allow to do the quick reconfiguration of the technological process when the composition of the raw materials and the requirements of product characteristics are changed, etc. in relation to the prediction and management of quality indicators of road and construction bitumens, methods of getting formal models that relates bitumen quality indicators with technological parameters of their production both for classical regression equations and for formal neural networks. The method of getting such models has been worked out on abstract dependencies with further adaptation of the production of bitumen. According to the received formal models the automated process control system can solve both the direct problem of predicting quality indicators by substituting the input technological parameters for the model input, and the inverse problem using nonlinear programming methods to minimize the deviation functions of the quality parameters obtained from the model from the target values given operator technologist.

The article shows the possibility of describing complex objects with parallel functioning components in the form of structures built on the basis of neural networks. The neural network is represented by an operator matrix, that is, a formal description that gives a universal way to solve many non-standard control problems. Matrix apparatus is shown to significantly improve the efficiency of the method compared to previously known. It is concluded that the representation of the neural network by the operator matrix provides a universal way to solve the problems of transport and information flows management; neuron-like systems based on such representation of the neuron are able to catch complex nonlinear relationships, self-improvement, learning in the process of use. Their use provides ample opportunities for finding and implementing effective solutions to the problems of management and control of flows

The article describes the algorithm of recognition of schematic diagrams in the framework of structural design of complex technical objects. It is specified that at statement of a problem of development of the specialized vectorizer it is necessary to define: software subsystems of the simplest tracer; algorithms of the analysis of images; formats of representation of the end result; initial data (formats) for recognition. As a result, it was concluded that for structural and circuit design, during which the vertex of the final portrait of the graph of the projected system is replaced, obtained after optimization by the criterion of the set of the smallest external stability, it is necessary to recognize images of graphic elements. The proposed algorithm allows for adequate recognition of the elements of electronic circuits, which further makes it possible to automatically replenish the database of elements with new elements in a given format.

The paper considers the main factors determining the quality of underground water deposits within the RO, done hydrochemical and geoecological assessment of groundwater RO. The entropy of the groundwater ecosystem is calculated. It was found that most of the deposits have an entropy of less than 30%. that is, the water is clean enough, not experienced external influences. However, the water quality has deviations in individual indicators from the requirements of SanPiN 2.1.4.1074-01, which can be eliminated by conventional methods of water treatment.

The paper reports that there currently exist various technologies and methods for achieving energy efficiency of reconstructed buildings and facilities. It highlights the fact that practically all mansard construction technologies conform to the up-to-date requirements for energy efficiency and resource conservation. At the same time, the analysis of a number of foreign and national publications shows that the modern trends in ensuring energy efficiency of buildings and facilities are based on the use of solar, thermal and biocincrete panels, which also prove to be environmentally friendly.

This paper logically continues the first part of the work describing roof construction with the use of translucent materials. The analysis of the current tendencies in the construction of roofs for sports and entertainment facilities showed that the contemporary studies are focused on the development of sliding roofs and the most recent trends feature façade and roof coatings made of ethylene copolymer and tetrafluorethylene based (ETFE) film. This paper discusses the most prominent advantages of membrane cushion roofing in the light of the summary analysis covering the articles of foreign authors. It mentions that ETFE cushion roofs are also used to restore buildings and structures of historical significance. The paper goes on to suggest a new structure of sliding roof and describes the construction technology taking into account the experience of building ETFE cushion roofs.

In this article we consider technique of determination of degree of homogeneity of heterogeneous mixtures by using tool contactless method. This method uses optoleptical information of mixture surface. This method can be used in automatic control systems. An optoleptical information may be obtained using standard devices of photosensitive scanning. The value of entropy of otptoleptical information is used to estimate the degree of mixture homogenization. Operations of component mixing are widely used in technological processes. The degree of homogenization of mixture is the one of quality indicators of mixing process. The degree of homogenization is usually determined by laboratory method, which requires additional time for analysis. The degree of homogenization can also be determined by using the senses. In this case, the results of determination depends on the experience of the expert. In this article we looked at an example for the paint industry. The method can be applied to a wide range of heterogeneous composition.

The purpose of this work was to study the influence of the structural and geometric parameters of the twist drill on the quality of the processed hole and productivity of machining the high strength polymeric composite material – glass fiber epoxy-based plastics that are reinforced by titanium foil. In the structure of high loaded polymeric composite parts the reinforcing layers made from the titanium foil are used. These titanium layers are placed between layers of the winding unidirectional glass fiber tape or the carbon fiber tape. In order to reach the required dimensional accuracy, the macro- and micro geometry of the hole surfaces, to eliminate the overheat, burning, and delaminations of material, need to use sharp-edged tools, which wear out quickly, and remove the drill from the workpiece at frequent intervals to clean the chips from the flutes of the drill and the hole being drilled. We studied the drilling of glass fiber reinforced laminates at the different schemes of sharpening the drills made from the high-speed steel. We present some experimental results of the optimal feed and speed for the studied twist drills, the dependencies of the highness parameters of roughness, and also characters and degree of delamination at starting and finishing hole for the different tools, feed and cutting speed.
