Fire resistance evaluation of reinforced concrete floors with fire-retardant coating by calculation and experimental method

With the help of a previously developed technique based on the solution of inverse and direct problems of heat conductivity, the fire resistance of a hollow-core reinforced concrete floor with “Neosprei” fire- retardant plaster coating was estimated. The thermal and physical characteristics, as well as characteristics of the fire-proof ability of “Neosprei” fire-retardant plaster coating, have been determined. The conclusion has been made on the effectiveness of this coating and on the boundaries of the fire-retardant coatings use to ensure the normed values of the fire resistance degree of hollow-core reinforced concrete floors, including in the mining industry

Issues of copyright for objects created by artificial intelligence

The paper substantiates the problem of recognising artificial intelligence as the author of intellectual property objects. The conditions of copyrightability and the possibility of compliance of copyright objects created by AI with such requirements are given. The article contains answers provided by artificial intelligence at our request. The article issues of types of objects that AI can create are being studied. Authors paid attention to problems of compilation and plagiarism in things made by AI. The research proves that objects created by AI can meet all copyrightable requirements. The authors emphasised that the only exception is the normative condition that only a human can be the author. It was concluded that the impossibility of recognising AI as the work's author is an artificial limitation. The authors emphasised that such a paradigm will change in the future. The authors suggest that the current state of AI is very close to the stage of deterministic understanding of human free will. AI is a surrogate representation of human intelligence with similar properties for analysis, self-improvement, and decision-making

Соціокультурний вимір та сучасна інтерпретація теорії суспільного договору

Purpose of Article. The purpose of the article is to reveal the socio-cultural dimension of the theory of social contract, to comprehend the basic determinants of service-oriented public policy through the implementation of a comparative analysis of theories of "contractionism" ("contractualism") and "clientelism" ("clientism"), especially in the clarification of functional relationships between subjects and objects of interaction in the context of their historiography and modern use. Methodology. The methodological basis of the study is a comparative and systematic analysis, as well as historical logical and retrospective methods that ensured the study of the theories of "contractionism" ("contractualism") and "clientelism" ("clientism") in the historical context of development and interpretation of modern development of the Ukrainian state, allowed to reveal the essence and highlight the ideology and socio-cultural foundations of service-oriented public policy. Scientific novelty. The scientific novelty consists in expanding theoretical ideas concerning the ideology of constructing a service state and the role of customer-oriented relations in international and national practice of public governance. The service orientation is substantiated as the basic principle of the transformation of the system of rendering of governance services. Conclusions. The relevance of the concept of a public contract (social contract) is substantiated by the necessity for practical implementation of the ideology of the service state. The basic principles of contractualism and constructive dialogue as the value orientations of modern integration processes in Ukraine are determined. The importance of contractualism as a mechanism of constructive dialogue in the conditions of functioning of a social contract is substantiated. The achievement of social consensus through the conclusion of a social contract is considered as the basis for the development of civil society, and, at the same time, a guarantee of the legitimacy of power. At the same time, the destructiveness of clientism (clientelism) in the relationship between government and civil society is substantiated.Цель статьи – раскрыть социокультурное измерение теории общественного договора, осмыслить базовые детерминанты сервисно-ориентированной государственной политики через осуществление сравнительного анализа теорий "контракционизма" ("контрактуализма") и "клиентизма" ("клиентелизма"), особенно при выяснении функ- циональных связей между субъектами и объектами взаимодействия в контексте их историографии и современного использования.

Justification of Ice Melting Power on 10 kV Overhead Power Lines

The fuzzy multicriteria model of the ice melting system on radial 10 kV overhead power lines was developed. Three criteria were taken into account: the minimum of reduced annual costs for ice melting system, the minimum of amount of electric energy not provided to consumers during melting, and the minimum of the amount of electricity consumed for the ice melting. The model also takes into account the fuzzy limitation of the permissible ice melting power associated with the uncertainty of weather conditions. Based on the model we justified the value of ice melting power, which should be provided by serial ice melting devices of industrial production, intended for use on radial 10 kV overhead power lines, taking into account the uncertainty of initial data

How to write a Wikipedia article

How to write an article on Wikipedia is a question that is relevant for many people who contribute to this reference web portal. The creators of Wikipedia have provided various sources from which you can find answers to the main questions. The authors of this study aimed to identify and analyze the main recommendations offered to users who write or edit Wikipedia articles. The results of the study suggest that the basic rules for writing and editing articles include the following: using information from published materials and avoiding personal ideas, opinions, considerations, reflections, dubious or unproven facts; using published materials from reliable independent sources that can be verified; presenting facts, interpretations, and theories without editorial sympathies or bias in order to achieve neutrality (a neutral point of view); and providing complete information covering all aspects that must be described proportionally according to their importance. The authors conclude that these rules are logical and reasonable and are best suited for amateurs who, without adequate knowledge and experience, aim to write acceptable reference content

Method of Detecting Radio Signals using Means of Covert by Obtaining Information on the basis of Random Signals Model

The article presents a developed method for determining random radio signals. Random signals can be signals from hidden means of obtaining information.The signal is considered as a random process. The description of such signals is based on probability theory and the theory of random functions. In the practice of analysis of random radio signals, static methods based on the theory of stationary random functions have become widespread. The existing models of a stationary random process are not adequate for a large number of random processes, especially for processes that are dynamic in nature and are observed during a finite time interval.The developed method allows to detect signals from hidden means of obtaining information with greater efficiency. The novelty of the method is to determine the deviation of the main parameters of the signals from the function of the sample. The method is based on determining the function of a sample of signals of a given radio range. The function of the sample is obtained as the implementation of the smoothing function of a random process, by the method of least squares using the principle of sliding smoothing.It is proposed to determine the signals of the means of covert receipt of information by the instantaneous deviation of the parameters of random signals. To determine the signals of the means of covert obtaining information, it is proposed to determine the deviation of the amplitude of the random signals from the amplitude of the signals of the sample function, then, if necessary, to determine the deviation of the signal phases. So, the effectiveness of the method is achieved by determining two parameters of the deviation of the amplitude and phase. This makes it possible to detect random signals with a higher probability.Determining the function of the sample of the required radio band significantly increases the probability of determining random signals, by reducing the scanning time of a given radio band, by excluding known signals from the additional software analysis of a given radio band

Blood Plasma Serotonin and von Willebrand Factor as Biomarkers of Unstable Angina Progression Toward Myocardial Infarction

Aim: To investigate the serotonin and von Willebrand factor (vWF) concentrations among unstable angina (UA) patients without and with progression toward myocardial infarction (outcome) and to assess the utility of both as prognostic markers of UA complications. Materials and methods: In observational cohort study, we recruited 103 patients with ischemic heart disease (the median age 65.0 (59.0-69.0) years, 45 females (43.7%)). After full set of investigations including high sensitive Troponin I test and 28-day follow-up period, we defined three groups: Group 1 - stable angina patients (n=22) as control, Group 2 - UA patients without outcome (n=71), Group 3 - UA patients with outcome (n=10). We analyzed the blood plasma serotonin content by the ion-exchange chromatography with measurement of serotonin on fluorescence spectrophotometer. VWF concentration was determined by ELISA. We compared the concentrations of observed parameters among the groups with the Kruskal-Wallis test (with post-hoc Mann-Whitney test with Bonferroni-Holm correction). We assessed binary logistic models, receiver operating characteristic curves, calculated sensitivity (Se), specificity (Sp), and positive likelihood ratio (LR+) for each indicator. Results: We registered elevation in serotonin concentration and decline in vWF concentration in Group 3 in comparison with Group 2 (22.670 (20.687-24.927) μg/ml vs 11.980 (8.120-15.000) μg/ml, p< 0.001, and 0.117 (0.109-0.120) rel.units/ml vs 0.134 (0.127-0.143) rel.units/ml, p < 0.001) and Group 1 (12.340 (10.052-13.619) μg/ml, p < 0.001, and 0.137 (0.127-0.156) rel.units/ml, p < 0.001), respectively. No significant differences in serotonin and vWF concentrations between Group 1 and Group 2 were detected (p=0.81 and p=0.36, respectively). The probability of outcome increased significantly (by 60.7% and 59.7%, LR+ 19.0 [6.0, 60.0] and 18.0 [3.9, 80.0]) if serotonin concentration was above 21.575 μg/ml (Se=80.0%, Sp=95.8%, AUC=0.975) and vWF concentration was below 0.114 rel.units/ml (Se=50.0%, Sp=97.2%, AUC=0.973), respectively. Conclusions: Serotonin and vWF as biomarkers are demonstrated promising results for rule-in the patients with risk of short-term UA progression toward myocardial infarction
