Much attention is paid to the spheres of such devices application and specific requirements to the operators, performing the control of these devices. </em></p> <p><em>Main reason of the unsatisfactory realization of the tasks, carried out by the remotely controlled devices is human factor. In greater part of cases it occurs due to the discrepancy of the qualities of the person to the functions, performed by the remotely controlled devices operator. For this reason in the process of the selection of the staff for such activity it is necessary to take into consideration psychophysiological aptitude of the candidate. Among the set of the personal qualities professionally important qualities (PIQ) are determining for the successful professional activity. The paper defines main professionally important qualities of the operator of remotely controlled devices. For the assessment of the basic PIQ of the operator the authors suggest to use psychologic testing, applying Cattell`s sixteen personality factor questionnaire. For the evaluation of the candidate aptitude for the work with the remotely controlled devices fuzzy model, based on Mamdani-type inference is developed. Each factor of the model is presented by the linguistic variable, for which the set of values is determined. Output linguistic variable for which the term-set of values is determined, Gaussian function is selected as the membership function. The base of fuzzy rules is constructed. The developed fuzzy model is planned to be used in the automated system for the assessment of the candidates in the operators of the remotely controlled devices.</em></p> Vasyl Kychak Leonid Koval Vitaliy Makogon Copyright (c) 2021 2021-03-04 2021-03-04 3 10.31649/2307-5392-2020-3-1-5 DEFORMATION ENERGY OF THE TRANSPORT MEANS IN THE CONDITIONS OF THE TRAFFIC ACCIDENTS <p><em>The article considers the method for assessing the energy of deformations of the transport vehicles in road traffic accidents (RTAs). The intensity of the transport vehicles operation, as well as the increase in their number is accompanied by numerous accidents. In most cases, accidents are caused by the violation of speed limits. In this regard, methods, able to assess the strain energy consumed during the impacts of motor vehicles are relevant. The determination of the energy of deformation and destruction of the structural elements of vehicles is important for determining the speed of the transport vehicles motion before a collision. Besides, information, regarding the energy used to deform vehicles in road accident conditions allows vehicle manufacturers to reduce the amount of expensive, less informative and extremely inflexible car tests. In the given research, the problem of estimating the energy before a collision, based on full-scale tests is solved. On the example of automotive technical expertise, initial data were obtained to determine the values of the speeds of automobiles, as well as their deformation energy absorbed during the impact.</em></p> <p><em>The essence of the model for assessing the strain energy is that any inelastic impact between transport vehicles leads to an equivalent elastic impact, which takes into account the total energy consumption, including the work of deformation, the work of the forces of resistance to the displacement of the transport vehicles in the process of the repulsion after the impact and kinetic losses in the process of the impact. The reliability of the developed method for assessing the energy of deformation of vehicles in the condition of the traffic accident is confirmed. Based on full-scale tests, the strain energy is determined by the energy equivalent method and the hardness method. Satisfactory convergence of the results of calculating the strain energy by two methods is shown. The results obtained confirm the reliability of determining the speed calculated by these methods, as well as using a surveillance camera. The hardness method, proposed as an alternative to the energy equivalent method, enables to calculate the energy in the conditions of the traffic accident of any transport vehicles, including cars for which ”crash-tests” are not carried out.</em></p> Vitaliy Ogorodnikov Tetiana Arkhipova Copyright (c) 2021 2021-03-04 2021-03-04 3 10.31649/2307-5392-2020-3-18-23 THEORETICAL SUBSTANTIATION OF «ENGINE-DRIVER-TRAIN-TRAFFIC OPERATOR» SYSTEM IMPROVEMENT <p>The paper presents the mathematic model which reflects various factors of negative impact on the quality of the decisions taken by the operator of the transport system, its components are: professional training, labour conditions and work place organization, operation mode and rest mode, degree of uncertainty &nbsp;of the &nbsp;information, arriving to the operator. The concept of the description of the fault-free operation system is suggested. Algorithm of obtaining different variants of operators labour activity protection against faults emergence and the algorithm of the selection of the most rational variant are determined. Analysis of the results of the social studies regarding the problems of the most labour-consuming operator functions is carried out. On the base of the analysis of the set of factors, which influence the quality of the decisions taken by the operator of the transport system, the system, providing the error-free operation of both train operator and engine-driver is suggested, the base of the system is mathematic model. Mathematic model, simulating the error-free operation of the transportation process and technical facilities with the necessary reliability, is developed. The technique of transport system operator training in order to obtain qualitative training with the needed reliability is highlighted. Reliability dependences of the transport system operator professional training on the number of training cycles and different matrices of transient probabilities are obtained, the approach, regarding the determination the time (training cycles), necessary for achieving the preset training reliability is formed on their base. The parameters of the environment which provide the necessary probability of the correctness function realization by the operator, are determined. Calculations of the resulting function of error-free work of the transport system operator, using all the elements are carried out. Optimal reliability of the operator is determined on the base of consideration of n<sup>th</sup> number of different variants of the environment parameters and selection of the variant with minimal total expenses.</p> Natalia Chernetska-Biletska Igor Baranov Marija Miroshnikova Sergiy Kuzhel Copyright (c) 2021 2021-03-04 2021-03-04 3 10.31649/2307-5392-2020-3-24-32 STUDY OF THE SPREADING DYNAMICS OF THE SOLID MUNICIPAL WASTE MANAGEMENT METHODS IN UKRAINE <p>Aim of the research is the determination of the regressive dependences, which describe the dynamics of the spreading of the methods of solid municipal waste management in Ukraine. Among the main methods of solid municipal waste management the following ones were considered: waste burial, burning, processing, recycling, composting. In the course of the research the method of regression analysis of the results of single-factor experiments and other pair dependences with the selection of the best kind of function from the most widely-spread variants by the criterion of maximum correlation factor is used. Regression was carried out on the base of the linearized transformations, which enable to reduce the non-linear dependence to the linear one. Determination of the regression equations coefficients was carried out by the developed computer program "RegAnaliz", protected by the certificate of state registration of the rights to the copyright object. Adequate regression &nbsp;dependences, describing the spreading &nbsp;dynamics of&nbsp; the methods of solid municipal waste management in Ukraine and allow to forecast the spreading of such methods of waste management as waste burial, burning, processing, recycling, composting, have been obtained. Graphic dependences, describing the spreading dynamics of&nbsp; the methods of solid municipal waste management and allow to illustrate the dynamics and show the sufficient coincidence of the theoretical and actual results have been constructed. It is established that in Ukraine the spreading of the solid municipal waste burial drops hyperbolically, burning – changes according to the quadratic dependence, processing and recycling – grows hyperbolically and composting – grows according to the power – law dependence. The spreading of solid municipal waste composting increases most intensively. The following spreading of the methods of solid municipal waste management in Ukraine in 2021 is forecast: waste burial – 93.68%, burning – 0.41%, processing and recycling – 4.02%, composting – 0.121%.</p> Oleg Bereziuk Copyright (c) 2021 2021-03-04 2021-03-04 3 10.31649/2307-5392-2020-3-6-11 3D-BIOPRINTING AND DEVELOPMENT OF THE DENTAL IMPLANTATION CLASSIFICATIONS <p><em>Regenerative medicine as an independent branch &nbsp;was formed at the end of the last century</em><em>. </em><em>The</em> <em>given</em> <em>scientific</em> <em>direction</em> <em>comprises</em><em>: </em><em>cellular</em> <em>technologies</em><em>, </em><em>cellular</em> <em>therapy</em><em>, </em><em>sub</em><em>-</em><em>cellular</em> <em>surgery</em><em>, </em><em>targeted</em> <em>therapy</em><em>, </em><em>3D-bioprinting, dental implantology, etc</em><em>. </em></p> <p><em>Discoveries in the sphere of medical-biological science during the recent thirty years and modern information technologies promoted the development of the regenerative medicine, which occupies leading positions in science</em><em>. </em><em>From</em> <em>the</em> <em>point</em> <em>of</em> <em>view</em> <em>of</em> <em>organization</em><em>-</em><em>systemic</em> <em>positions</em> <em>the</em> <em>regenerative</em> <em>medicine</em> <em>can</em> <em>be</em> <em>considered</em> <em>as</em> <em>a</em> <em>complex</em> <em>system</em> <em>of</em> <em>scientific</em><em>-</em><em>engineering</em><em>, </em><em>practical</em> <em>and</em> <em>bioethical</em> <em>measures</em><em>, </em><em>which</em><em>, </em><em>using</em> <em>the</em> <em>mechanisms</em> <em>of</em> <em>the</em> <em>tissue restoration,</em> <em>regeneration</em><em>, </em><em>morphogenesis, available in human organism </em><em>, </em><em>is</em> <em>able</em> <em>to</em> <em>regenerate</em> <em>adequately the structures and functions of the injured organ or tissue</em><em>. </em></p> <p><em>Proteomic</em> <em>studies</em><em>, </em><em>research</em><em>, </em><em>using</em> <em>cellular</em> <em>technologies</em><em>, </em><em>tissue</em> <em>engineering</em><em>, </em><em>technology</em> <em>of</em> <em>creating</em> <em>biomaterials</em><em>, 3</em><em>D</em><em>-</em><em>printing</em> <em>and</em> <em>other</em> <em>modern</em> <em>technologies</em> <em>are</em> <em>referred</em> <em>to</em> <em>the</em> <em>most</em> <em>advanced</em> <em>directions</em> <em>of</em> <em>the</em> <em>regenerative</em> <em>medicine</em> <em>development</em><em>. </em><em>However</em><em>, </em><em>the</em> <em>availability</em> <em>of</em> <em>numerous</em> <em>classifications</em> <em>creates</em> <em>the</em> <em>information</em> <em>contradiction</em><em>, </em><em>when</em><em>, </em><em>on the </em><em>&nbsp;</em><em>one</em> <em>hand</em><em>,</em><em> the </em><em>&nbsp;</em><em>more</em> <em>classifications</em> <em>are</em> <em>used, the</em> <em>more</em> <em>information</em> <em>the</em> <em>doctor</em> <em>gets</em><em>, </em><em>and</em> <em>on</em> <em>the</em> <em>other</em> <em>hand</em> <em>– </em><em>the more</em> <em>separate</em> <em>classifications</em> <em>are</em> <em>proposed</em> <em>to</em> <em>the</em> <em>doctor ,the &nbsp;greater is the probability of taking the multivalued decision as a result of the redundant information, which will be different for each specialist, both by the volume and by the content</em><em>.</em></p> <p>The research contains the integrated classification of the means of dental implantation, based on new class of the dental implants-intelligent dental implants and three new classification features, that provided the solution of the information contraction and achieving &nbsp;the information balance, elimination of the multivalued decisions and the redundant information.</p> Sergey Zleplko Sergey Tymchyk Mykhaylo Palamarchuk Leonid Koval Andriy Dushkevich Copyright (c) 2021 2021-03-04 2021-03-04 3 10.31649/2307-5392-2020-3-12-17
