Earth’s Stratospheric Aerosol Parameters Reconstruction from Polarimetric Measurements of the Sky

Earth’s climate changes are the result of natural changes in the energy balance of Sun irradiation and influence of anthropogenic factors on the variations of ozone layer thickness and stratospheric aerosol abundance. It is developed a miniature polarimeter for satellite polarimetric experiments in the ultraviolet region of the sunlight spectrum. The main task of this device is to the obtain an information on the stratospheric aerosol physical properties. We tested this polarimeter on a bench specially designed and manufactured as well. It is possible to measure by it the phase dependences of the degree of linear polarization (DLP) of solar radiation scattered by the Earth’s atmosphere. A set of special computer programs was developed for comparing the spectral polarimetric measurements DLP data of cloudless sky with model calculations of DLP for the artificial gas-aerosol medium. Thus, the prototype of satellite polarimeter as well as special computer programs make it possible to study the Earth’s atmosphere aerosol physical characteristics.

Development of the automated system for assessing radiation risks to the population of the Russian Federation based on the data of radiation-hygienic certification of territories

The assessment of the radiation risk based on the data of the radiation-hygienic passports of the territories makes it possible to give a brief quantitative characteristic of the negative impact of sources of ionizing radiation on the health of the population of various regions of the Russian Federation at the population level. The calculation of individual indicators of radiation risk for the population of particular region of the Russian Federation is a time-consuming task that requires referring to radiation-hygienic passports of territories for particular years. Therefore, the purpose of the performed work was to develop specialized software designed to assess the indicators of radiation risk to the population of the Russian Federation according to the data of the radiation-hygienic certification system of territories. Automation of the calculation of radiation risk allows not only to simplify the calculation procedure but also to carry out a spatial-temporal analysis of risk in dynamics for different regions of the Russian Federation over long periods. The methodological basis for the software development is guideline MR 2.6.1.0145-19 “Calculation of radiation risk according to the data contained in the radiation-hygienic passports of the territories to provide a comprehensive comparative assessment of the radiation safety status of the population of the subjects of the Russian Federation”. To achieve the set goal, two computer programs were developed: 1) to automate the process of calculating radiation risk based on the information contained in the radiation-hygienic passports of territories, a computer program “Calculation of radiation risk indicators according to RGPT data”; 2) for the spatial visualization of the calculations, a specialized geographic information system “Radiation risks of the population of the Russian Federation according to radiation-hygienic certification data”. The computer programs developed in the course of the work allow an automated calculation of radiation risk based on the data of radiation-hygienic passports of territories, visualize the spatially distributed results of calculating radiation risk, carry out a preliminary assessment of the state of radiation safety, based on the data contained in radiation-hygienic passports of territories using radiation risk indicators.

Review of the theoretical approaches regarding the legal protection of objects generated by artificial intelligence systems in the field of copyright and related rights

Keywords: artificial intelligence, copyright, related rights, sui generis The publication provides a descriptive review of existingtheoretical approaches regarding the legal protection of objects generated byartificial intelligence systems in the field of copyright and related rights, namely.1) The inexpediency of legal protection of computer-generated objects. It is concludedthat the absence of legal regulation and free circulation of generated objects isconsidered the easiest option. Still, hardly fair and justified, as the creation of artificialintelligence systems requires large and significant investments in their development.2) The possibility of protecting computer-generated objects by copyright as originalworks. It has been established that extending the concept of «originality» to computergeneratedobjects seems unjustifiable.3) The introduction of the latest iteration of the fiction theory and establishing aspecial legal status for artificial intelligence systems. It is noted that such an approachseems premature because the existing artificial intelligence systems are amanifestation of «narrow» or «weak» artificial intelligence and not artificial generalintelligence.4) Protection of specific generated objects through related rights. It is concludedthat the objects generated by AI systems may be protected in Ukraine through theprism of related rights, under the condition that the relevant object can be attributedto a phonogram, videogram, or broadcast (program) of broadcasters respectively.5) Protection of generated objects through a special legal regime under copyrightlaw. It is described that this approach cannot be considered a universal example forimitating the legal protection of objects generated by computer programs because itsapplication leaves more questions and inconsistencies than solving the problem onthe merits.6) Protection of generated objects through sui generis law. It is assumed that applyingsuch an approach to the protection of objects generated by computer programswill not lead to significant changes in copyright and will protect the interests and investmentsof developers of artificial intelligence systems.

The methods of implementing the activities are: planning, implementing, and evaluating activities. At the activity planning stage, the team coordinated and discussed with supervisors, subject teachers (ICT and Science), and school principals. At the activity implementation stage, the team trained students in using software applications, namely Microsoft Office and PhET. Applications in Microsoft Office that are chosen to be trained to students are Excel, Word, and PowerPoint. Meanwhile, PhET Simulation taught to students is the topic of Static Electricity. The training schedule for Microsoft Office uses ICT subject time, while for PhET uses Science subject time. At the activity evaluation stage, the team together with the supervisors identify the obstacles experienced and the improvement efforts made every week. The team also coordinated and discussed with ICT subject teachers, science teachers, and school principals about the follow-up plan of the training activities. The training provided by the team on technology adaptation in the form of using software applications has improved the skills of junior high school students in using computer programs, namely Microsoft Office and PhET.

Regulation of the Smart Contract in (Romanian) Civil Law

The research aims to organize, examine, and analyze the provisions on smart contracts available in Romanian civil law. “Smart contracts” are not smart, and are not necessarily contracts, although they can be. As self-executing computer programs, smart contracts are operational on the blockchain and unlike traditional legal contracts, once the agreement has been concluded and the smart contract is set in motion, no party can intervene and it will be executed without interruption, modification, or breach. The crucial question in the final contract law topic is what happens when the smart contract's outcomes deviate from those required by law. To answer this issue, we must first understand that whether a smart contract becomes legally enforceable is determined by several circumstances, together with the unique use case, the type of smart contract employed, and the existing legislation. The paper addresses the subject of determining and regulating smart contracts under Romanian current laws. Particular emphasis is placed on two ambiguous definitions of smart contracts: as computer code and as a civil-law contract. The authors conclude that the concept of smart contracts requires more legal regulation, particularly in terms of managing their meaning and comprehension.

THE COMPLEX OF ANCIENT OBSERVATORIES ON THE TABLE MOUNTAIN IN INGUSHETIA

The proximity of the three ancient sanctuaries to each other on the flat top of the Table Mountain against the background of the sacred peaks of Kazbek and Tsey-Loam, the opportunity to observe the sunrises and sunsets in the highlands of the Caucasus, cosmogonic myths, all this gave an assumption about the astronomical functions of these sanctuaries. The purpose of the study was to prove that these ancient sanctuaries were used by the priests to determine the key moments in the annual cycle of the Sun and were a calendar. This is proved by using special computer programs and calculators that determine the azimuth and altitude of the Sun; instrumental observations and measurements on the ground. It is established that the shrines of Myat-Seli and Myater-Dyal on Table Mountain in Ingushetia are a complex of medieval solar near-horizon observatories. And it is hypothesized that these sanctuaries were built on the site from which solar cycles were observed from about the beginning of the 1st millennium BC. This work also provides prerequisites for determining various astronomical observations from sanctuaries and the presence of other ancient observatories in the Caucasus. A method has been developed for searching for prehistoric solar, lunar and stellar near-horizon observatories.
