Authors: Chen Qiyong , Lin Enqiang , Champagne Victor K. , Nardi Aaron , Müftü Sinan
Published: January 2023

In this study, finite element models are used to simulate the impact of porous WC-Co and Al particles cold sprayed onto substrates of the same materials. Effects of high strain rate, heat generation due to plasticity, interfacial friction, heat transfer, and material damage and failure are taken into account as are differences in the initial kinetic energy and strength of the materials. It was found that the influence of porosity increases with impact velocity and that the pores channel stress waves in unique ways not observed for solid particles. The results suggest that using porous particles for solid-state consolidation, as in cold spraying, could have advantages in terms of energy dissipation, although further investigation is required.

Authors: Rojas O. , Prudent M. , López M.E. , Vargas F. , Ageorges H.
Published: January 2023

This study assesses the influence of atmospheric plasma spraying parameters on splat stacking and porosity formation in bioglass coatings prepared from commercial powders. Coating samples were deposited on stainless steel substrates using spraying parameters established through numerical simulations. Different Ar-H2 mixtures were used as the forming gas, and plasma current and spraying distance were varied. Coating microstructure and phase composition were determined by SEM and XRD analysis. Although numerical simulations for each parameter set predicted a suitable Sommerfeld number for proper splat stacking, Na2O and P2O5 volatilization occurred during spraying, promoting the formation of porosity in the coatings. Denser coatings were obtained, however, by adjusting the gas mixture ratio, plasma current, and spraying distance such that enthalpy of the plasma jet is sufficient to overcome the glass transition temperature of the powder and at the same time avoid the evaporation of volatile oxides.

Authors: Azarmi Fardad , Tangpong X.W.
Published: January 2023

This study compares the microstructure of Al2O3 coatings produced by detonation gun spraying (DGS) and laser stereolithography (SLA). The SLA samples mostly consisted of alumina and voids, while the DGS-deposited alumina contained additional features such as splats, pores, cracks, and boundaries. DGS deposits were also denser with about 3% porosity compared to 8% porosity in the SLA samples. EDS analysis showed that both coatings contained only aluminum and oxygen, although additional carbon was detected in the SLA samples, indicating the presence of residual binder (resin based) material. XRD analysis revealed a mixture of α and γ-Al2O3 phases in the DGS coatings, but no phase change in the SLA samples.

The Development of Next Generation Wear Plate Overlays Using Big Data
Authors: Vecchio James
Published: January 2023

This study shows how data-driven modeling tools aid in the development of alloys that meet specific processing, property, and performance requirements. By leveraging a “big data” approach, two new alloys were designed that outperform commonly used materials in hardfacing and wear plate overlay applications. Over one million alloy compositions were analyzed to find two with the right combination of matrix and hard phases to provide the desired level of impact and abrasion resistance. The difference between the two alloys is in their matrix phase; one being austenitic, which has higher toughness, the other being martensitic, which has higher resistance to abrasive wear.

Authors: Ma Xinqing , Rivellini Kristina , Ruggiero Peter , Wildridge George
Published: January 2023

The aim of this work is to find a path toward a thermal barrier coating (TBC) that is more thermally stable and less thermally conductive than current 8YZS coatings. The concept of dual-phase composite ceramics is proposed in an effort to combine the desirable attributes of unique phase constitution, low conductivity, and high ceramic fracture toughness. In addition, efforts are made to optimize the spraying process for low-k ceramic topcoats by controlling the effect of key parameters on porosity, deposition rate, and deposition efficiency. Isothermal oxidation and thermal cycling tests are conducted to evaluate the performance of the low-k TBCs with promising results.

Authors: Kou Cong-Cong , Chen Xu , Zhang Shan-Lin , Li Cheng-Xin , Yang Guan-Jun , Li Chang-Jiu
Published: January 2023

Rare-earth complex oxide ceramics are promising candidate materials for next-generation thermal barrier coatings due to their low thermal conductivity and phase stability. During plasma spraying, the component with a higher vapor pressure may experience severe preferential vaporization, resulting in significant composition change from the starting powder. In this study, Gd2Zr2O7 (GZO) powder with a hollow spherical structure is used as the feedstock material to assess the vaporization behavior of Gd2O3 during atmospheric plasma spraying (APS). Isolated Gd2Zr2O7 splats with regular disc shapes in different sizes were deposited on stainless steel substrates at a deposition temperature of 300 °C to study the effects of particle size on vaporization loss. The elemental composition of each splat was analyzed by EDS, and the ratio of Gd to Zr in different splats with different diameters was obtained. The results show that the vaporization loss of Gd increases markedly with decreasing particle size due to the preferential vaporization of Gd2O3. Using Gd2Zr2O7 powders of a certain size can reduce Gd loss, although the effect is determined by molten droplet size rather than apparent powder particle size.

Published: January 2023

Traffic density in the terminal control area will increase flight safety risks. One effort to reduce the risk is to minimize the controller’s workload when affected by air traffic complexity. This research uses a simulation model to measure air traffic complexity in terminal control areas. The aircraft performance model has been constructed from ADS-B data and represents the aircraft movement in the terminal control area of Soekarno-Hatta International Airport. The simulation model can detect and resolve conflicts to keep separations between aircraft at a specified minimum separation limit. Air traffic complexity measurement uses several indicators, i.e., aircraft density, number of climbing and descending aircraft, aircraft type mixing, conflict control, aircraft speed difference, and controller communication. The weighting factor for each indicator has been obtained from Jakarta Air Traffic Service Center (JATSC) controller perception using an analytic hierarchy process. The simulation results show that the variation of resolution type affects the complexity level significantly. The results of this study can be used as consideration for improving air traffic control procedures and air space structures.

Analytical Model of Subthreshold Swing for Junctionless Double Gate MOSFET Using Ferroelectric Negative Capacitance Effect
Authors: Jung Hakkee
Published: January 2023

An analytical Subthreshold Swing (SS) model is presented to observe the change in the SS when a stacked SiO2-metal-ferroelectric structure is used as the oxide film of a JunctionLess Double Gate (JLDG) MOSFET. The SS of 60 mV/dec or less is essential to reduce power dissipation while maintaining transistor performance. If a ferroelectric material with Negative Capacitance (NC) effect is used, the SS can be reduced below 60 mV/dec. The analytical SS model of the ferroelectric NC FET presented to analyze this was in good agreement with the SS derived from the relation between the drain current and gate voltage, using 2D potential distribution. As results were derived from the analytical SS model, it was found that it is possible to obtain an SS of 60 mV/dec or less even at 15 nm channel length by adjusting the thicknesses of the silicon channel, SiO2, and ferroelectric. In particular, the change in SS according to the ferroelectric thickness was saturated as the thickness of SiO2 increased and was almost constant as the thickness of the silicon channel decreased.

Published: January 2023

The metaverse is the conjunction and optimization of the possibilities of the Internet and technology at their best. It is a consequence of the development and evolution of digital society. Technological innovation, fundamentally oriented toward virtual reality, augmented reality, and mixed realities, contributes significantly to the creation of a solid foundation on which to build an entire universe of virtual worlds. This is a universe that, in turn, requires the creation of backbone content for narratives that attract and retain users by capturing their attention to promote a specific ecosystem that transfers the activities of the real world to a virtual one, either projected or recreated. This research is based on a systematic review of 402 articles and a qualitative analysis of 125 publications. It examines the trends in technology, application, and methodology pertaining to the metaverse in the social sciences field, namely marketing and communication and neuroscience, areas that contribute to the understanding of the social dimension of the metaverse phenomenon. Although there is abundant academic literature on the metaverse in computer science, this is not the case in the aforementioned disciplines. Given that the metaverse is destined to become the next Internet revolution, there is a race among countries and brands to position themselves within it, which is expected to intensify in the coming years. The metaverse can contribute to a wide variety of applications of a social nature, which is why it is a highly competitive tool for nations, companies, and academia, as well as the public and private media. The results indicate a technological transformation proposing a future that includes neuro-technologies based on brain–computer interfaces and the metaverse as the setting. This will occur alongside the solidification of the virtual ecosystem thanks to the emergence of digital natives and Gen Z, as well as the convergence of many different technologies and immersive and participatory content, in which the consumer is the provider, owner, and beneficiary.

Authors:   Western Ukrainian National University, Bolkvadze Nataliia
Published: January 2023

Abstract. Introduction. The world market has been dictating the requirements of an innovative and non-standard approach of doing business for the last decade. Thus, the economy is gaining signs of socio-political and socio-cultural spheres of life. The concept of strategic development in the field of creative industries is widely used in Europe and United States. The practical adaptation of this new society direction is only gaining popularity In Ukraine. Creative industries and services that emerged at the crossroads of art, culture, business, and technology are developing today in the world economy. In particular, dance industry is one of the most important areas of development in the cultural and leisure segment of the economy. The development of the dance business is becoming more profitable and promising because of the growing dance popularity in society. Purpose. The aim of the study is to analyse the development of creative industries in Ukraine on the example of dance studios, and identify existing problems in the development of entrepreneurship in this sphere of activity. Results. The advantages of the creative industries development for national economies are determined. The main advantages are getting profit from exports and imports; increasing employment rates, and the number of small businesses. Activity and pace of development of a dance studio are influenced by a number of factors that can either slow down or speed up this pace. Instability of the economic and political situation in the country, low purchasing power of the population, high rents, rising utility costs, and the unwillingness of entrepreneurs to adopt foreign experiences also lead to stagnation in the development. Dance studios are often exposed to administrative risks associated with rent increases, various fines and inspections. Price risk is now most pronounced, as many people lost their jobs and sources of income during the pandemic and war. Also, prices for training, seminars, and competitions began to rise due to the falling of the Ukrainian economy and rising inflation. All this factors significantly reduces the desire and ability of the population to spend money, and, as a result, there is a decline in dance studios. Conclusions Among the main problems hindering the development of the Ukrainian dance industry are low support for the creative sector by the state and a lack of proper legislative, organizational, and information base for this sector. There is a lack of programs and funds that would provide favorable conditions for the development of the creative potential of individual dancers and dance groups. There is no financial assistance to raise awareness of the Ukrainian dance sector in the international market. Overcoming the problems outlined above, ending the war in Ukraine, and improving the business climate will be able to make this sector of the economy profitable and potentially attractive to investors.

Published: January 2023

Abstract. Introduction. The article analyzes current issues of transformation of the education system in accordance with the Bologna system, taking into account globalization trends, achieving compliance with the information society and finding new forms and methods of higher education, which creates preconditions for intensifying the introduction of computer technology education (ZVO). Purpose The purpose of this article is to study the scientific and methodological foundations of training future economists on the basis of computer technology, which creates real opportunities for their use in education in order to develop creative abilities of students. Results. The analysis of scientific works on the information state of society and the introduction of computer technology in the educational process of free economic science. Attention is paid to the introduction of modern approaches to the training of future economists using computer technology. The role of information and subject complexes, which form the basis of pedagogical software, which is a powerful tool for improving the efficiency of the teacher and improving students' perception of educational material. It has been proven that the application of computer-based learning technologies is the development and use of educational software. The peculiarity of computer-based learning technologies is that they must accumulate in themselves, along with the computer program, the didactic and methodological experience of the subject teacher. The main problem that is seen here is the development of methods for computerization of the discipline. It is possible to either completely restructure and focus on creating new computerized courses, or to implement a methodology with partial computer support of the discipline, which, in our opinion, is more acceptable. The use of information and communication technologies in the process of training future economists has a number of advantages - the ability to control the pace of educational activities, choose the level of complexity of tasks, the ability to clearly demonstrate certain phenomena. New computer technologies open access to non-traditional sources of information, increase the efficiency of independent work, create space for creativity, acquisition and consolidation of professional skills, allow the implementation of fundamentally new forms and methods of learning. Their introduction changes education in general. Conclusions. Therefore, when teaching economic disciplines, there are enough reserves to increase its effectiveness with the help of computer technology. However, following this direction, it is necessary to find a balance in the system "teachercomputer-student".

Abstract. Introduction. Participants of the territorial community are united by a common territory of permanent residence, social interaction with each other, common territorial interests and needs of local significance, self-identification, common values and historical events, communal property, etc. Purpose. The purpose of the article is to deepen the theoretical and methodological foundations of the organization of socio-economic development of territorial communities. Results. The main shortcomings in the functioning of territorial communities are highlighted, among which: the presence of differences in the priority needs of communities and actions by local authorities to meet them; lack of a coordinated feedback mechanism with the local population; insufficient level of quality of services provided by local authorities; insufficient number of employees in local authorities. It is emphasized that the introduction of equal programs of socio-economic development is not rational because each region or community needs special, specialized actions by the authorities. The principles on the basis of which the voluntary association of territorial communities in Ukraine is formed are determined, among which: constitutionality and legality of the process of association of territorial communities; voluntariness of the subjects of the association; economic efficiency; state support; ubiquity of local self-government; transparency and openness; responsibility. Factors influencing the development, approval and implementation of programs of economic and social development of individual territorial communities are systematized, namely: political; ecological; financial and economic; social and others. Conclusions. It was found that the list of indicators of socio-economic development of the united territorial community should contain indicators that characterize the demographic situation; economic efficiency of the united territorial community; financial self-sufficiency; quality and availability of public services; creating comfortable living conditions. The structural elements of the plan of socio-economic development of the united territorial community are considered and it is emphasized that the main results of the plan of development of the territorial community should be published in regional media in order to adhere to the principles of transparency, openness and transparency.

Abstract. Introduction. Financial market penetration in terms of both knowledge and accessibility has become more extensive and widespread as a result of economic globalization. This financial development was followed by an increase in funding demand on the financial market. Bonds and sukuk are two financial instruments that are very attractive to investors. Bonds are a type of debt activity agreement that is licensed through a debt certificate, whereas sukuk are certificates that have the same value and are evidence of ownership of a project or certain investment activities such as assets, benefit rights, and services. Purpose. This research aims to identify and analyze the risks and returns of corporate bonds and sukuk listed on the Indonesia Stock Exchange, as well as to determine whether ROA influences the yield spreads of bonds and corporate sukuk listed on the Indonesia Stock Exchange. Results. The research demonstrates that the return on corporate sukuk is greater than the return on corporate bonds, the risk of corporate sukuk is greater than the risk of corporate bonds, there is a significant difference in return between bonds and corporate sukuk, there is a significant difference in risk between bonds and corporate sukuk, and the Return on Assets (High ROA) significantly decreases yield spreads on corporate bonds and sukuk. Conclusions. The rate of return on corporate sukuk as calculated by Yield to Maturity (YTM) is greater than the rate of return on corporate bonds, while the level of risk of corporate sukuk as calculated by Value at Risk (VaR) is lower than the level of risk of corporate bonds. There is a significant difference in return when corporate sukuk and corporate bonds are measured by Yield To Maturity. High Value at Risk (VaR) and Return on Assets (ROA) indicate a large difference in risk between corporate sukuk and corporate bonds, which considerably reduces yield spreads on sukuk and corporate bonds.

This article analyzes the experience of Ukrainian higher education institutions in measuring the quality of educational activities in the context of quality assurance. Based on the study, it is established that in developing regulatory provisions for quality assurance, higher education institutions are guided by regulations of Ukraine (Law of Ukraine "On Higher Education", "On Education") and other documents (Standards and recommendations for quality assurance in European Higher Education Area, ESG 2015, European Association for the Quality Assurance of Higher Education (ENQA), European University Association (EUA), European Association for Higher Education (EURASHE), international rankings indicators). Criteria for accreditation, framework procedures and rating assessment criteria are used to measure the quality of educational activities in Ukrainian higher education institutions. It is determined that the use of ranking is not a popular component of the group of criteria for assessing the quality of higher education, although this indicator provides an opportunity to classify according to various criteria and is more indicative for determining the competitiveness of higher education. After all, the prospects of using rankings as a criterion for measuring the quality of educational activities is the possibility of ranking higher education institutions by competitive quality, analysis of the functioning of higher education institutions, which provides opportunities to improve the quality of educational services.
