  • Investigation of micro-dimensional metal structures obtained by electric explosion of conductors (part 2)

    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.

  • Environmental assessment of recreational facilities in Rostov-on-Don

    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.

  • Implementing IoT applications using the Akka agent model

    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.
