The Role of International Law in the War on Illicit Drugs
Authors: Lloyd Chidi
Published: April 2021

The paper evaluates the role of international law in the so-called fight against illicit drugs. It assesses the harm caused by the non-medicinal use of such drugs, finding that this does indeed exist but recognising that the very rendering of drugs as illicit may also cause such harm. The key harms here are human rights violations and the undermining of personal autonomy. The work argues that an effective framework for the control of drugs should seek to mitigate the harm associated with drug use with minimal restrictions on autonomy. It submits that the international framework cannot be considered as effective in this regard, and that it is underpinned by Western notions of morality from the mid-20th Century rather than any objective assessment either of harm caused by drugs. It is shown that the framework does not envisage a clear role for States in managing the type of drug problems.

До числа основних проблем досліджень бездротових сенсорних мереж (БСМ) відносяться моделювання та управління топологією мережі з метою підвищення її зв'язності, а також маршрутизація з мінімальними часовими і енергетичними затратами. В роботі здійснено порівняння можливих топологій БСМ між собою та розглянуто статистику кінцевої затримки, пропускної здатності, завантаження. Ре-зультати вказують на те, що деревоподібна мережа має більшу пропускну здатність і кінцеву затримку. Крім того, згасання погіршує продуктивність мережі та накладні витрати на маршрутизацію. Зроблено висновок, що продуктивність мережі з топо-логією зірки прийнятна для малих мереж, тоді як на основі сітки найкраще підходить для мереж з великою кількістю мобільних вузлів.

Published: April 2021

The content, properties and peculiarities of interoperability are considered in relation to integrated hierarchical systems. The structure of a unified element for the functional interaction of the levels of the hierarchical system is proposed. This element is common for interacting systems, performs different functions in these systems, and is built in the form of a finite state machine with a controlled structure. A computer program for modeling the interaction of the levels of a hierarchical system is proposed. An example is given of modeling the interaction of systems using the proposed unified element, which confirmed the possibility of interaction between systems by controlling the behavior of one automaton with the help of another.

The tests were performed on ER7 steel according to EN 13262. Based on the hardenability test (GOST 5657) by the method of end hardening (Jomen) the distance from the surface from which unilateral cooling was performed, where the hardness met the requirements of regulatory documentation for wheels of test steel, and the distance where the formation of needle structures, including bainite and otmanshtette, no longer took place. Simulation was applied in the software package QForm VX 8.2, as a result, a model was developed, for the adaptation of which the results of the experiment were used. Confirmed the high convergence of the results of the calculation and the experiment. At the same time, the model allowed to obtain an instantaneous cooling rate in a form that is more in line with the physical meaning of the process and to avoid the scatter of actual values associated with the discreteness of data capture. It is established that the instantaneous cooling rate changes in the process of continuous uniform supply of the cooler. The permissible range of cooling rates of the surface and central sections of the wheel rim during accelerated cooling of ER7 steel is determined. The data can be used to improve the heat treatment modes of railway wheels of current production in order to achieve a high set of mechanical properties both with the existing cooling technology and with differentiated cooling on the modernized equipment of the thermal section of the wheel shop. The developed model can be used to build thermokinetic diagrams under continuous cooling and to develop recommendations for heat treatment modes to achieve the specified mechanical properties under a certain structural state.
Estimation of the numerical efficiency of global optimization methods
Authors: Kosolap Anatolii
Published: April 2021

Currently, test problems are used to test the effectiveness of new global optimization methods. In this article, we analyze test global optimization problems to test the numerical efficiency of methods for their solution. At present, about 200 test problems of unconditional optimization and more than 1000 problems of conditional optimization have been developed. We can find these test problems on the Internet. However, most of these test problems are not informative for testing the effectiveness of global optimization methods. The solution of test problems of conditional optimization, as a rule, has trivial solutions. This allows the parameters of the algorithms to be tuned before these solutions are obtained. In test problems of conditional optimization, the accuracy of the fulfillment of constraints is important. Often, small errors in the constraints lead to a significant change in the value of an objective function. Construction of a new package of test problems to test the numerical efficiency of global optimization methods and compare the exact quadratic regularization method with existing methods.The author suggests limiting oneself to test problems of unconstrained optimization with unknown solutions. A package of test problems of unconstrained optimization is pro-posed, which includes known test problems with unknown solutions and modifications of some test problems proposed by the author. We also propose to include in this package J. Nie polynomial functions with unknown solutions. This package of test problems will simplify the verification of the numerical effectiveness of methods. The more effective methods will be those that provide the best solutions. The paper compares existing global optimization methods with the exact quadratic regularization method proposed by the author. This method has shown the best results in solving most of the test problems. This paper presents some of the results of the author's numerical experiments. In particular, the best solutions were obtained for test problems with unknown solutions. This method allows solving multimodal problems of large dimensions and only a local search program is required for its implementation.

For designing routes of sink drawing pipes a certain assortment it is necessary to choose correctly the initial sizes of preparation, to calculate admissible deformations on diameter and a wall. Sink drawing to pipes after short-drawing drawing or rolling on cold rolling mills, ie pipes having a certain difference.When designing routes to drawing it is necessary to predict in advance the size and direction of change wall thickness. The analysis of influence and its character for each parameter on change of wall thickness is carried out. Taking into account the analysis and the nature of the identified dependences, tested the construction of multiple linear and nonlinear regression to determine the wall thickness of the workpiece by , , , , .To order to assess the accuracy of the pipes after sink drawing, technological routes of pipes production from carbon steel grades were developed and investigated. According to the developed routes by the production technology, batches of tubes were drawn, samples were taken from each batch and wall thickness measurements were made at equally distant points of pipe cross-section.According to the results of measurements, correlation-regression analysis was performed, factors influencing the variation of difference were determined and regression models were built.With a small diversity of the workpiece (less than 3%) the diversity of the finished pipes increases, with a diversity of the workpiece 3 ... 4% the diversity of the finished pipes changes little and > 4% the diversity of the finished pipes decreases.The intensity of the correction ( <1) depends on the compression ratio in diameter : the larger the value , the more intense the correction of the difference. That is, to correct the difference ( >4%) in the sink drawing, it is necessary to increase the coefficient of extraction.The results of research are introduced into the calculations of routes and technological maps of production in order to predict the diversity of finished pipes during drawing and supplemented the software for determining the size of the workpiece when designing routes for drawing carbon cold-formed pipes by sink drawing.

The goal of the paper is to create a training model based on real raw noisy data and train a neural network to determine the behavior of the fuel level, namely, to determine the time and volume of vehicle refueling, fuel consumption / excessive consumption / drainage.Various algorithms and data processing methods are used in fuel control and metering systems to get rid of noise. In some systems, primary filtering is used by excluding readings that are out of range, sharp jumps and deviations, and averaging over a sliding window. Research is being carried out on the use of more complex filters than simple averaging – by example, the Kalman filter for data processing.When measuring the fuel level using various fuel level sensor the data is influenced by many external factors that can interfere with the measurement and distort the real fuel level. Since these interferences are random and have a different structure, it is very difficult to completely remove them using classical noise suppression algorithms. Therefore, we use artificial intelligence, namely a neural network, to find patterns, detect noise and correct distorted data. To correct distorted data, you first need to determine which data is distorted, classify the data.In the course of the work, the raw data on the fuel level were transformed for use in the neural network training model. To describe the behavior of the fuel level, we use 4 possible classes: fuel consumption is observed, the vehicle is refueled, the fuel level does not change (the vehicle is idle), the data is distorted by noise. Also, in the process of work, additional tools of the DeepLearning4 library were used to load data training and training a neural network. A multilayer neural network model is used, namely a three-layer neural network, as well as used various training parameters provided by the DeepLearning4j library, which were obtained because of experiments.After training the neural network was used on test data, because of which the Confusion Matrix and Evaluation Metrics were obtained.In conclusion, finding a good model takes a lot of ideas and a lot of experimentation, also need to correctly process and transform the raw data to get the correct data for training. So far, a neural network has been trained to determine the state of the fuel level at a point in time and classify the behavior into four main labels (classes). Although we have not reduced the error in determining the behavior of the fuel level to zero, we have saved the states of the neural network, and in the future we will be able to retrain and evolve our neural network to obtain better results.

The importance of the effective study of the initial programming course (CS1), on the one hand, and the need to take into account the requirements for IT professionals today, on the other hand, encourage universities to flexibly change educational components, adjust curricula and disciplines. The relevance of finding approaches that positively affect the effectiveness of learning the basics of programming, due to the complexity of this course for students and the high level of dropout in the first session.The paper analyzes the approaches of foreign universities in teaching the CS1 course. The tendencies of the Ukrainian IT labour market concerning the need for adjustment of the content of the Algorithmization and programming course (Ukrainian analogue CS1) are investigated.It is established that there is no universal solution to the problems associated with teaching the initial programming course in the universities. Important factors that positively affect the success of programming training are the motivation of students, a set of didactic processes and methods, as well as good knowledge of the subject by teachers. To increase the effectiveness of training, researchers propose to change the programming language used in the introductory programming course and to introduce new classes of tasks in the curriculum. The effectiveness of the solutions depends on the regional specifics and traditions of IT education.Considering the ranking of programming languages in demand in Ukraine, the need to establish a relationship between disciplines and specifics of courses, the appropriate scheme of using programming languages are C / C ++ in Algorithmization and programming course (CS1) and then Java / C # in Object-oriented programming course (CS2). Another solution is to collaborate with IT companies and to involve students in writing real programs.

System approach to data analysis of pandemic development and forecasting
Authors: Bakhrushyn Volodymyr
Published: April 2021

The Covid-19 pandemic is one of the greatest challenges to humanity of last decades. Effective prevention of its development is the problem of decision-making with many criteria, high uncertainty of the results of a choice, insufficiently understood feedbacks. There has been collected statistics on the main indicators of the pandemic over the past year. However, according to most researchers, the initial data on the number of infected and fatal cases are significantly underestimated. This makes inaccurate other important indicators, in particular, those that characterize the nature of the dynamics, the rate of infection and its mortality. At the same time, a large number of research results provide additional sources of information to improve the quality of pandemic analysis and forecasts. Mathematical models infections spreading have been significantly developed, which make it possible to refine individual indicators.According to model estimates, the maximum number of daily cases can be 50 times higher than the official data, and the dates of maxima can be up to 4-5 weeks earlier. For Ukraine, the highest values of "excess mortality" (as a percentage of the average level in 2015 - 2016) were observed in September (15.8%), October (20.3%), November (33.7%) and December (29.2%). In January 2021, according to incomplete preliminary data it is expected the significant reducing of the indicator to the value less than 2%. Per 100 thousand inhabitants, the "excess mortality" in 2020 was about 38.8 thousands (in the first 5 months there were negative values of the indicator), and for the period from June 2020 to January 2021 - about 53.5 thousands, or 14.1% of the base level for this period. An analysis of Google's search queries gives grounds to assume that in early January 2020, the pandemic spread in many countries on different continents, and precautionary measures were taken too late.The obtained data show that the involvement of additional sources of information makes it possible to compensate for the imperfections of official operational data and to un-derstand better the patterns of occurrence and development of Covid-19 pandemic. At the same time, a system approach to decision-making on prevention the development of a pandemic should take into account the information on morbidity and mortality statistics as well as other information, in particular on virus mutations, re-infection, vaccination, testing, socio-economic consequences etc. This should be the subject of further research.
