Navigating Decision Making with Generalized Temporal Intuitionistic Fuzzy Sets and Soft Sets
Authors: Kamacı Huseyin , Petchimuthu Subramanian , Ozlu Serif
Published: November 2024

The study addresses the challenges posed by evolving data within generalized intuitionistic fuzzy sets. Traditional methods often fall short in handling such complexity. To overcome this, we introduce the concept of a generalized temporal intuitionistic fuzzy set, extending the traditional framework to incorporate temporal dynamics. Additionally, we define a generalized temporal intuitionistic fuzzy soft set, integrating temporal aspects into the soft set framework. Recognizing the need for advanced operations like union and intersection to merge opinions across different periods, we propose practical solutions for decision-making in this dynamic context. Two novel multi-criteria decision-making methods are introduced, specifically designed to address decision-making problems within generalized temporal intuitionistic fuzzy soft sets. We develop Scilab codes for these methods, enabling the creation of a multiple-input single-output system. This system is applied to complex real-life examples, involving numerous parameters, time moments, and decision-makers. This comprehensive approach aims to provide robust tools and methodologies for decision-making processes amidst the intricate dynamics of temporal data within the framework of generalized temporal intuitionistic fuzzy sets.
Rings Whose Invertible Elements Are Weakly Nil-Clean

Published: November 2024

Westudythoseringsinwhichallinvertible elements are weakly nil-clean, calling them UWNC rings. This somewhat extends results due to Karimi-Mansoub et al. in Contemp. Math. (2018), where rings in which all invertible elements are nil-clean were considered abbreviating them as UNC rings. Specifically, our main achievements are that the triangular matrix ring Tn(R) over a ring R is UWNC precisely when R is UNC.Besides, the notions UWNC and UNCdocoincide when2 ∈ J(R). Wealso describe UWNC2-primal rings R by proving that R is a ring with J(R) = Nil(R) such that U(R) = ±1+Nil(R). In particular, the polynomial ring R[x] over some arbitrary variable x is UWNC exactly when R is UWNC. Likewise, we furthermore apply the obtained results to group rings showing that if G is a locally finite p-group and R is a UWNC ring such that the prime p is a nilpotent in R, then RG is too a UWNC ring. Some other relevant assertions are proved in the present direction as well.
Harry Potter, a teenage conspiracy myth
Authors:   Université Paul-Valéry Montpellier 3, CUEILLE Julien
Published: November 2024

The Harry Potter series of novels (1997-2007) by J. K. Rowling features a teenage protagonist who is pursued by a group of conspiring wizards who want to kill him and seize power. But Harry himself is a member of a secret society that resorts to conspiracy. And another reading might see in Harry a young man who shares many traits with certain contemporary adolescents, particularly the search for self, narcissistic flaws and interest in fictional plots. This article examines the articulations and issues of these different forms of conspiracy in J. K. Rowling’s successful work. On the basis of the (socio-)anthropological and psychoanalytical representations that inform it, it shows that the imagination of conspiracy that fuels the journey of Harry Potter gives it a mythical dimension that allows its many readers to achieve self-learning.
Female workers, the sensitive part of labor: L’Excès-L’Usine by Leslie Kaplan and Daewoo by François Bon
Authors:   CELIS, Université Clermont Auvergne, NASRALLI Abdelhamid
Published: November 2024

For a long time reduced to a mere energy power, to a machine for production, the working body regains its human and sensitive dimension in the literary production that accompanied the economic crisis of the last three decades. Starting from the 1980s, literary representations of the body are indeed impacted by social and economic changes and the physical and psychological damage they have caused. Incorporated into the flesh and mind, these social violences make the bodies of workers the very principle of their identity and, therefore, the place of questioning for the entire contemporary society.
Outsourcing in the automotive industry of the Kyrgyz Republic: Development prospects
Authors: Abilpeissov Kanash , Adieva Ainura
Published: November 2024

The study was conducted to assess the prospects for the development of outsourcing in the automotive industry of the Kyrgyz Republic and its impact on productivity, economic efficiency, and innovation in the industry. The study used statistical analysis methods to process data on production and employment from official sources, a comparative analysis of successful examples of international cooperation, and methods for assessing risks associated with outsourcing. As a result of the study, it was established that outsourcing in the automotive industry of the Kyrgyz Republic helps to reduce operating costs and increase production efficiency. It was also determined that the transfer of non-core functions to external contractors allows companies to focus on key processes, which accelerates the introduction of innovations. It was also confirmed that outsourcing helps to attract international companies, stimulating economic growth, and creating new jobs. However, the risk of loss of control over the quality and timing of tasks, which requires the development of effective mechanisms for interaction with contractors to minimise possible negative consequences, is identified. The study showed that the successful implementation of outsourcing requires the active participation of government agencies to create a supportive regulatory framework and incentives to attract investment. The results demonstrated that outsourcing contributes to the development of related industries such as auto parts manufacturing and IT services, which in turn stimulates the growth of the local labour market. In the long term, the use of outsourcing can become a key factor in increasing the competitiveness of the country's automotive industry in the international arena. The study provided valuable data on the impact of outsourcing on the efficiency and innovative development of the automotive industry, which can serve as a basis for developing strategies to optimise production processes and improve economic performance in this industries

This study explores how quantum computing might revolutionize music. Given the rising demand in this field, we investigate applying quantum principles and functionality to offer developers and quantum computing experts new opportunities. We provide a complete performance evaluation using two different techniques to combine quantum superposition for pitch generation and the Basak-Miranda algorithm for rhythm generation. Ultimately, we demonstrate that backend code derived from quantum principles can successfully play back music by creating a web application. We envision a future where quantum computing expands the limitations of musical creation, stimulating innovation and pushing the boundaries of artistic expression.

The paper presents the results of a study on the possible causes of differences in the structure and properties of the material samples of the FA`s cover (the screen type of the BN-350 reactor), depending on the temperature and duration of the post-radiation tests. It has been established that prolonged aging of the samples of the BN-350 reactor fuel assembly material up to 5000 hours leads to an increase in the concentration and size of carbide precipitates (such as Me23C6). It is assumed that changes in the microstructure: the grain size, the concentration of secondary precipitates, the displacement of carbides to the grain boundaries and their accumulation at triple junctions, occurs not only with an increase in the test temperature in short-time intervals (650–1050 °C isochoric annealing), and also in long-time exposure to high temperatures (5000 h, 400 °C, 600 °C, isothermally annealed).

INDUCED SEISMICITY MONITORING IN THE REGION OF THE STAROBIN POTASSIUM SALT DEPOSIT OF BELARUS
Authors: Aronov A. G. , Aronov G. A.
Published: November 2024

The paper presents the results of a long-term seismological monitoring within the Starobin potassium salt deposit of Belarus carried out since 1983 till 2017. The seismicity not directly caused by specific deposit mining conditions, but due to the underground rock excavations is discussed. The fact of the induced seismicity manifestation is caused by the fault activation in the salt mining region as a result of changing the stress conditions in the horizons subject to the action of the natural tectonic forces. Spatially, the seismicity manifestations are observed beyond the mine field limits and involve the territories adjacent to the mining region. The averaged values of the seismicity increase are weakly dependent on the mining excavation features, but, firstly, on the geometry of the faults found in the region and the pattern of the regional tectonic stresses.

EXPERIMENTAL STUDY OF DISTRIBUTION OF PERTURBATIONS FROM THE LITHOSPHERE TO IONOSPHERE AT THE EXAMPLE OF UNDERGROUND NUCLEAR EXPLOSIONS AND EARTHQUAKES
Authors: Salikhov N. M. , Pak G. D.
Published: November 2024

Lithosphere-atmospheric-ionospheric relations have been investigated at the example of the perturbations propagation from the lithosphere to ionosphere during underground nuclear explosions at the Semipalatinsk test site and two earthquakes (Mb = 3.5 and Mb = 3.6) near Almaty. Simultaneously, seven days prior to the earthquake the abnormal effects in variations of intensity of a gamma-ray flux, temperatures, acoustic impulses and the Doppler frequency shift of ionospheric signal are registered by a complex of the measuring equipment installed in the mountain area. A retrospective analysis of the recordings of the Doppler frequency shift of ionospheric signal variations during the UNEs at the Semipalatinsk test site detected disturbances in the DFS records 15–18 minutes after the explosion and the response of ionosphere to the acoustic wave. The anomalous effects recorded in ionosphere when UNE radioactive products penetrated the atmosphere and when gamma-ray flux increased prior to earthquake, apparently have a common mechanism for disturbances perturbation to ionosphere, namely, the ionization change of the atmospheric boundary layer leading to the total current change between the ionosphere and the Earth.

A large volume of scientific and research activities is currently carried out in substantiation of new projects on nuclear reactor safety, in which high emphasis is placed on “beyond-design basis” accidents, in spite of the fact that applied technical solutions reduce the probability of such accidents occurrence. To study parameters of severe accidents and develop measures to mitigate consequences an experimental base is necessary, which enables emergency situation modelling maximally close to real conditions. The National Nuclear Center (NNC) – the leading research organization in the atomic sphere in the Republic of Kazakhstan – possesses such an experimental base, providing scientific and technical support for peaceful uses of nuclear power, involving studies oriented towards the improvement of nuclear reactor safety [1]. The article presents the concept and general results of researches carried out on NNC’s experimental base in substantiation of nuclear reactors safety, realized in collaboration with JAEA, which is a key foreign partner in this area, as well as current plans on new experimental program implementation.

Possibilities of experimental study of the model fuel assembly (FA) destruction of ASTRID reactor in a severe accident were studied in this paper. Experiments with model FA can be carried out in a research impulse graphite reactor (IGR) [1] in the framework of joint program between RSE NNC RK and CEA, called SAIGA (SAIGA – Severe Accident InPile experiments for Generation IV reactor and Astrid project) [2]. ASTRID reactor core consists of an inner zone with heterogeneous FA in height, in which the principle of separation of high enrichment fuel into two zones (upper and lower) is applied by fuel layer with a low uranium-235 content, intended for the reproduction of fission substances, and an external zone with homogeneous FA [3]. The study considers two versions of the model FA for reactor tests, which differ in the geometry and composition of the fuel elements installed in them. Test modes of model FA are determined and complex calculations on their justification is conducted.

This paper shows the results of mechanical tests in a wide temperature range of reactor graphite and beryllium oxide. It is established that the compressive strength of graphite with increasing temperature test up to 1000 °C increases by ~10 %, while the fragile nature of the destruction is preserved. An increase in the test temperature leads to a sharp decrease in the strength properties of BeO by ~10 times. As shown by bending tests with increasing temperature, the destruction mechanism changes from brittle to brittle-viscous.

Authors: Kozlovskiy A. L. , Zdorovets M. V. , Dukenbyev K. , Kadyrzhanov K. K.
Published: November 2024

Nanostructured films based on TiO2  with a thickness of 620 nm were obtained by magnetron sputtering. The samples were irradiated at the DC-60 heavy ion accelerator of the Astana branch of the Institute of Nuclear Physics with Fe7+  ionswith an energy of 85 MeV at the fluence of 1×1011 to 1×1014 ions/cm2. The dependences of the change in defects concentration in the structure of thin films from the irradiation dose are established. A decrease in intensities of diffraction peaks indicates an increase in microdistortions in the structure, as well as the formation of regions of disorder. Evaluation of the effect of irradiation on amorphization and destruction of the crystal structure was carried out using a modified Griffiths criterion. It has been established that a decrease in the degree of crystallinity as a result of irradiation leads to the formation of amorphous inclusions in the structure and a decrease in the radiation resistance of thin films.

Recently, carbon materials containing fullerenes have been used as sorbents. The purpose of the study was to explore and compare the sorption properties with respect to heavy metal ions of fullerene-containing materials. This will allow choosing the most effective way of obtaining fullerene-containing sorbents for use in processes of cleaning of environmental objects. For our research, several types of sorbents obtained from shungite and graphite were selected. The results showed that fullerene-containing sorbents bind a significant part of pollutants and reduce the toxicity of the soil. Nevertheless, complete purification from metals is not observed. The obtained results are the basis for further studying the sorption properties of carbon nanomaterials and are of practical importance in the field of nanotechnology, ecology, ecotoxicology, chemical technology of inorganic substances and other.

The paper presents the results of a study of changes in the structural properties and magnetic structure of Fe nanotubes depending on the synthesis conditions. As a method of obtaining, the method of electrochemical synthesis from sulfuric acid electrolyte solutions was used, the voltage range was 1.25 to 2.0 V, with a step of 0.25 V. To study the influence of deposition conditions on the magnetic characteristics and the hyperfine magnetic structure of nanotubes, X-ray diffraction and Mossbauer spectroscopy were used. It has been established that the synthesized nanotubes are whisker-like structures with a textural direction of crystallite growth (110), a body-centered cubic lattice characteristic of the iron phase of the spatial system Im-3m (229). According to the Mossbauer data, the spectra of the studied nanostructures in the general case are a low-intensity Zeeman sextet and a quadrupole doublet characteristic of the paramagnetic state of the Fe2+ and Fe3 cations. The presence of a quadrupole doublet indicates the presence of impurity inclusions in the structure, which leads to a disordering of the magnetic texture, as well as the presence of a large number of cationic vacancies in the crystal structure. During the study, the dynamics of changes in the magnetic texture and the concentration of impurity inclusions from the synthesis conditions were established.

ANALYSIS OF RING-SHAPED SEISMICITY STRUCTURES IN THE REGION OF THE NORTHERN CAUCASUS: POSSIBLE PREPARATION FOR LARGE EARTHQUAKES
Authors: Kopnichev Yu. F. , Sokolova I. N.
Published: November 2024

We have been studying some seismicity characteristics in the region of Northern Caucasus since 1964. It was established that ring-shaped seismicity structure have been formed within depth range of 0–33 km prior to large Racha earthquake of 29.05.1991 (Mw=7,0). Seismicity rings are characterized by threshold magnitude value (Mt) and big axis length (L). Earlier we have obtained correlation dependences of Mt and lgL values on magnitudes of main events Mw for intracontinental earthquakes with mechanisms of reverse and oblique-reverse faulting, prevailing in the region of Northern Caucasus. Using these dependences we estimated magnitudes of large event which could be prepared in the area of ring structure: Mw=7,1±0,2 for the zone of the Racha earthquake. This value is close enough to real magnitude of the event mentioned. New big ring structures were identified at the western outskirt of the Great Caucasus and in the region of the Eastern Caucasus, where large earthquakes are not known according to instrumental and historical data. We estimated magnitudes of possible large earthquakes by characteristics of these structures: Mw=7,0±0,2 and Mw=6,9±0,2 in the regions mentioned respectively. Large seismic event, which probably is prepared at the westernmost part of the Great Caucasus, can represent a special danger due to great density of population and nearness of a few big cities: Krasnodar, Novorossiysk, Sochi etc. It is supposed that ring structures formation is a consequence of geologic systems self-organization, connected with deep-seated fluids migration.

Published: November 2024

The methodological aspects of a systematic approach to solving the problem of predicting the long-term geodynamic stability of the geological environment during underground isolation of radioactive waste in geological formations are discussed. The system approach acts as a way of organizing scientific research and is not so much a method of solving, as a method of setting tasks. It is especially important at the first stage of collecting and systematizing data on the study area. It also helps to focus efforts on identifying the fundamental laws of geodynamic development of the region, which determine the preservation of the insulating properties of rocks for a long time. The methodological aspects of a systematic approach to solving the problem of predicting the geodynamic stability of the geological environment during underground isolation of height-level radioactive waste in geological formations are considered.

Published: November 2024

Beryllium has been widely used in nuclear power engineering. In this case, it refers to rare metals, since its content in the earth's crust is ~ 510−4 %. A small prevalence in nature, a complex technology of extraction from ore and obtaining products determine its high cost [1]. In the process of using beryllium in nuclear power, various radionuclides accumulate in it, which limit its reuse. According to this, the problem of purification of irradiated in a nuclear reactor beryllium from radionuclides is topical.

The article discusses the principle of operation and the composition of the equipment of the direct flow irradiated berillium chlorination plant. This technology involves the conversion of beryllium and its radionuclides to chlorides, followed by their separation. The final product is beryllium chloride in liquid form

The paper presents the results of the study of the effect of ratios of reactive gases N2 and O2 on the structural phase state and the mechanical properties of nitrogen-containing titanium dioxide coatings obtained by reactive magnetron sputtering on the surface of AISI 304 stainless steel. According to the results of the X-ray phase analysis, the coatings contain titanium dioxide in the form of anatase, rutile and a small amount of brookite. It was found that with an increase in the nitrogen content in the working atmosphere, the volume fraction of anatase and rutile increases. An increase in the nitrogen content in the gas atmosphere leads to the formation of a quasihomogeneous surface texture with a less pronounced block structure. Based on the results of nanoindentation, it can be assumed that the formation of a quasihomogeneous texture can cause a decrease in the physicomechanical parameters of the coatings. It was established that the structure, phase composition, and mechanical properties of the coatings depend on the gas ratio N2/O2 in theт negative bias mode (Ubias = −150 V).

The article provides results of the radiation survey of a 1005 km2 area in the vicinity of “Balapan” site. Earlier research into the area adjacent to “Balapan” site served as a ground for the survey thereby revealing a large-scale area of soil contamination with 241Am. 241Am activity concentration in soil reaches values of ~200 Bq/kg. The research result showed that such a large-scale contamination is shaped as fallout “plumes” presumably caused by atmospheric tests on the “Experimental Field” ground. A feature of this contamination is a low content of fission and nuclear activation products commensurable with the global fallout background, which is uncharacteristic of nuclear fallout “plumes” formed by aboveground nuclear tests.
