MODELING THREADS AND THREADED CONNECTIONS IN THE SYSTEM OF THE AUTOMATED DESIGNING
DescriptionThe work was carried out not only in the scientific, but also in practical directions, the key part of which was the modeling of the system. Consideration of the presented modeling processes occurred on the basis of the delivered pedagogical experiment associated with the introduction in the discipline "Engineering Graphics" of a new tool for the military educational institution to obtain the final graphic design document. The purpose of the experiment included a comparative analysis of modeling tools (manual and machine) and their impact on the production of the final product (drawing). As a tool, the computer-aided design system Кompas-3D was used. The presented research was worked out in practical classes of the specified discipline, the theme of one of them was "Image of thread and threaded connections". With the help of the graphic editor Compass-3D, a model of the shaft and bushing with the specified thread profile was obtained, as well as the assembly unit based on them. The entire way of obtaining the above objects for convenience and ease of perception has been broken down into certain stages. The results of the pedagogical experiment were very satisfactory; the goal of the practical training was fully achieved

Description
A thermal physical and mathematical model of laser cladding with TiNi on steel was developed which allows us to monitor the formation of the structure and the properties of the surface layer. A description of the model included assumptions and simplifications; analysis of the energy balance; numerical modeling of thermal processes; evaluation of the temperature distribution; experimental verification of the obtained solutions. The composition of the steel and TiNi alloy was examined as a two-layer material with different thermal characteristics. The energy balance of the system was described with a heat equation in a three-dimensional form. The main channels of the radiation energy costs were taken into account: absorption surface of the product, loss owed to the reflection surface, energy absorbed by the coating which did not come down to the base material. To solve the differential equation of heat conduction we used the Fourier integral method. In assessing the temperature distribution we have reviewed a dimensional problem when exposed to a point source of the Gaussian distribution in a pulsed mode. Computer calculations used MathCAD graphs of temperature changes at different depths of the TiNi layer and the steel substrate. The results obtained allowed us to develop the recommendations for optimizing the technological parameters of laser cladding of TiNi. The simulation of thermal processes significantly reduces the time and resources required to develop the technology, allowing prediction of the quality of the surface layer during the development of the technology and promoting the adoption of efficient technical and technological solutions

MODELING OF MANAGEMENT SITUATIONS IN CONSTRUCTION OF REAL ESTATE OBJECTS
DescriptionThe article proposes an approach to constructing a methodology for modeling managerial situations in the construction of real estate objects using a hierarchical system and choosing a developer company to be charged with the construction of real estate. A comprehensive methodology has been developed on the basis of which it is possible to forecast problem situations that arise during the construction of a real estate object and conduct a scientifically valid choice of a developer company

MODEL OF INFORMATION EXPOSURE IN SOCIAL NETWORKS
DescriptionOn the basis of hydrodynamic analogy between turbulent transport of momentum, heat and mass transfer, and information in the conditions of modern electronic social networks, we consider a model of informational influence. The flow of information is represented as a stream of random events with simplest flow properties. In addition to the flow of information impact there were introduced the concepts of density, velocity and viscosity of the information flow. These parameters had been derived from the construction of dimensionless criteria characterizing the balance between inertia and viscosity of the information flow of information influence. This criterion serves as a numeric parameter determining the boundary of the transition from low-intensity to high intensity of information influence the turbulent nature of the attack. We have also analyzed the ranges of changes and the meaning of the entered parameters from the point of the organized network information inserts. The existence of the information in time and procedural nature of the concept of information allow us to focus on the properties of information flow as inertia, dynamics and relaxation

MODEL OF INFORMATION SECURITY FOR CONTROL PROCESSES OF COMPUTER NETWORKS
DescriptionIn order to improve the security of information transfer we have offered one of the possible approaches to modeling process control computer networks with elements of intelligent decision support. We proceed from the graph model of network nodes which are network devices with software control agents, and arcs are logical channels of information exchange between the equipment computer systems. We built an addressless sensing technology which ensures the completeness of monitoring of all network equipment. To classify the computer networks state we provided a method for calculating the values of reliability. Development of signal mismatch triggers the control cycle as a result of which the adjustment of the state of network equipment. For existing tools we proposed adding network control expert system consists of a knowledge base, inference mechanism and means of description and fill in the knowledge base

MODEL OF MANAGEMENT SYSTEM OF LABOR PROTECTION OF A MACHINEBUILDING COMPANY
DescriptionThe article considers a combination of the process-based and systematic approach in the management of OSH at the enterprise for the development of the OSH management system model. The OSH management system is created by the enterprise based on the model provision, the branch requirements and recommendations of the current standards. Features of the system are determined by the state of the external and internal environment of the enterprise (context). The context forms the basic requirements for the inputs of the system and determines its capabilities. An analysis of the context of the enterprise makes it possible to identify the system: describe its inputs and outputs, identify key stakeholders and consumers. Based on this analysis, a model of the OSH management system is suggested, which, in analogy with the modern model of the quality management system, allows us to identify the place of the OSH in the context of the organization, and also to clarify the interaction of the main groups of OSH

MONITORING OF INDUSTRIAL EMISSIONS TO THE ATMOSPHERE OF NOVOCHERKASSK SDPP
DescriptionWhen combustion of fuel in thermal power plants, combustion products are formed, which contain: fly ash, particles of unburnt pulverized fuel, sulfuric and sulfur dioxide, nitrogen oxide, gaseous products of incomplete combustion, sodium salts, soot particles, calcium dioxide, etc. Getting into the atmosphere, they cause great harm to the components of the biosphere. The article presents a laboratory analysis of industrial emissions into the atmosphere of 1-7 power units for 2015 and 2016 at Novocherkassk State District Power Plant. The components NO2, NO, CO, SO2, C (soot) have been determined. It is established that for the whole observed period of excess of maximum permissible emissions was not revealed. Emissions of each of the components are within the same level and are stable

MONITORING OF THE EFFICIENCY OF ASH CATCHING AT NOVOCHERKASSK SDPP
DescriptionThe electric method of gas dedusting is the most effective, since it allows capturing solid particles with a size from 0.01 µm to tens of microns. The efficiency of dust and gas cleaning equipment of Novocherkassk SDPP for cleaning flue gases from ash at power units 1-7 in the period from February 2015 to February 2017 is considered. The main equipment is electrostatic precipitators. As a solid fuel, Donetsk culm is used. It is established that the efficiency of waste gas purification at power units 5-7 was about 99 %, while at power units from the 1st to the 4th this value was within 95-96 %. The data obtained correspond to the design data, but it is recommended that the cleaning devices be improved to improve their efficiency. The most acceptable is a combined electrofilter-bag filter
