The environmental performance of recreational facilities in Rostov-on-Don was assessed. The object of the study were 15 parks and gardens of the city. Depending on the structure of the territory (the share of the green area, the density of tree planting), the parks were grouped into three groups. The influence of parks and gardens on microclimate parameters was studied - air and surfaces temperatures, air humidity. The greatest reclamation effect on the microclimate is possessed by parks with dense plantations (planting density of trees above 400 pcs / ha). Green spaces have the strongest influence on surfaces temperature, decreasing it by 11.4 - 13.8 ° С. The smallest changes are recorded for air temperature, which decreases on average by 1.9 - 2.3 ° C. Humidity increases by 2.7%. The presence of the effect plantations of trees at parks on microclimate parameters is proved by statistical methods.

The article presents the results of experimental studies of the parameters of micro-sized metal particles and sprayed films obtained by the method of electric explosion of metallic conductors (EVP) and electro-explosive spraying (EVN), respectively. Copper (Cu) and aluminum (Al) metal wires were used as explosive conductors. Geometrical parameters and physicochemical analysis of the obtained microparticles and thin films were carried out by means of the universal two-beam electronic system Versa 3D. From the analysis of the obtained samples of sprayed thin films and fine particles, it follows that with a discharge current density J≈10 ^ 10 A / m ^ 2 millisecond, the film thickness and particle sizes can reach values ​​less than micron scale.

The article deals with technologies that work with the Internet of things, and their implementation in various industries. The Internet of Things is considered as a higher level automation, therefore, it becomes possible to make automated complex logical decisions related to the choice of the structure of the process and operations, the assignment of technological bases and other similar tasks. A model based on a universal primitive called Actor for concurrent and distributed computing is considered. Covered issues of implementing an agent-based approach for applications of the Internet of things. The necessary condition for the implementation of the IoT model has been established; this is the possibility of scalability and the availability of fault tolerance configuration. To meet the real need for scalability, as well as fault tolerance, Akka provides comprehensive functions in routing, clustering, edging, and retaining agents. The use of the Akka framework for agent implementation has been analyzed.

The paper presents an analytical description of the unfolding surface of one of the products of light industry – aerodynamic shape. All surface elements are designed in the Maple environment based on the 4GL package commands. A set of commands allowing to describe surfaces and spatial curves analytically is proposed for the construction of 3D graphical objects. Elements sweep aerodynamic shape are conical and cylindrical sweep with a special character of their boundaries. The proposed description of the surface of the air shape allows you to design a technical product of specified geometric dimensions according to the calculated geometry of the elements of the air shape.

Fractal geometry is used in the development of new designs based on the principles of fractal shaping and the study of generations of fractal structures. The structure generation is characterized by optimization of the original geometry in the process of iteration. Fractal structures of older generations have the best indicators of reliability. The aim of the study is to develop an algorithm for modeling new designs based on the principles of fractal shaping. The development of fractal structures requires the creation of new technologies and materials.

In this paper, the concept of minimal intuitionistic dominating vertex subset of intuitionistic fuzzy graph was considered, and on its basis the notion of a domination set as an invariant of the intuitionistic fuzzy graph was considered. A method and an algorithm for finding all minimal intuitionistic dominating vertex subset and domination set were proposed. This method is the generalization of Maghout’s method for fuzzy graphs. The example of finding the domination set of the intuitionistic fuzzy graph was considered as well. The considered method and algorithm can be used to find other invariants, in particular, externally stable set, intuitionistic base and antibase of the intuitionistic fuzzy graphs.

The problem of designing and construction of objects of various purposes of an eco-sustainable type in urbanized areas is currently extremely topical. Directions and techniques used in theory and practice to improve the quality of the urban environment, still remain the subject of many scientific disputes and professional discussions. In their article, the authors propose to act in accordance with a number of environmental principles in order to solve urban-planning tasks of this kind on the territory of complex development. According to the authors, with an integrated approach to solving the problem, architectural and town-planning activities, modified according to the principles listed in the article, should ultimately contribute to the development of natural processes. In this case there will be a significant increase in the level of construction development of the territories in terms of the quality of the processes performed and an increase in the level of environmental safety.

Technical progress makes humanity create new technologies and methods in all spheres of life. Evaluation of property also in there. In current moment there are several methods, which are badly obsolete. For example, there are some cases, when building in decrepit or emergency condition were able to buy in cost several times higher than objective cost. These cases aren't unique. New method of evaluation of property could possibly help if not to stop in all appearing of this cases but less their amount. New method is based on Building Information Model (BIM). This model allow take all needed information about building in the currnet moment of time and see in dynamic, how change different indicators of building. This system can be more useful if it associates some amount of building, which differs indicators of interest building and reflecting effects of that building on themselves. This technology can be looked as Extented BIM. Consideration of implementing BIM in evaluation of property has very perspective vay - this can accelerate the time building can be evaluated, and also it let potential client to see all information about building which he need. This makes process of purchase-sale of property more clear, which, by turn, help avoid conflicts when property being researched before purchasing.

The article deals with the existing problems in our country, arising in the management of material resources in the process of construction of buildings and structures. The main problem in the material resources management system is that due to their late and incomplete delivery to the construction projects, there are significant downtime of working and construction machines and mechanisms. The don state technical University (DSTU) is developing an intelligent construction management system, which includes a method of planning and accounting for the movement of material resources to ensure synchronization of the processes of construction and installation works and their complete supply. The use of this technique allows to optimize the timing and volumes of supplies of material resources in accordance with a given technology of production operations and the simultaneous control of their inventory in the onsite warehouse

Today, catalysts based on zeolites containing transition metal ions are being intensively developed, ensuring the selectivity of the reaction of direct oxidation of methane to methanol. In current work, the X-ray absorption spectroscopy complimented with the structural models obtained in frames of the density functional theory were used to study the dependence of the local atomic structure of copper centers in mordenite type zeolites synthesized by solid-phase ion exchange using CuCl and H-MOR, upon the annealing temperature at different stages of synthesis. The typical Cu – O interatomic distances and the corresponding coordination numbers are determined. The dependence of the fraction of copper ions on the zeolite on the annealing temperature was established.
