Threshold Voltage Temperature Dependence for a 1.2 kV SiC MOSFET with Non-Linear Gate Stack
Authors: Boccarossa Marco , Maresca Luca , Borghese Alessandro , Riccio Michele , Breglio Giovanni , Irace Andrea , Salvatore Giovanni A.
Published: January 2024

The use of Silicon Carbide (SiC) power MOSFETs is becoming increasingly popular due to their unique properties, including a wide bandgap, higher critical electric field, and superior thermal conductivity compared to traditional Silicon (Si) MOSFETs. The reliability assessment of SiC power MOSFETs holds significant importance across various industries, such as automotive and aerospace, where these devices find numerous applications. One crucial aspect of their reliability is evaluating their performance during short-circuit (SC) events. To address this concern, this study employs TCAD simulations to analyze the behaviour of a SiC power MOSFET equipped with a gate insulator that consists of a stack of silicon dioxide (SiO2) combined with a non-linear dielectric (NLD) material. This NLD exhibits a Curie-Weiss temperature dependence, characteristic of ferroelectric materials. During short-circuit events, failures are often associated with temperature rises. The study demonstrates the effectiveness of using an NLD with a temperature-dependent permittivity (ε) as a gate insulator. By doing so, the temperature increase is mitigated, and the MOSFET’s ruggedness during short-circuit events is enhanced. This advancement in gate insulator technology could significantly improve the overall reliability and performance of SiC power MOSFETs in various applications.

Authors: SEFFAR ANDALOUSSI Sofya , HEMMI Mohamed
Published: January 2024

This article studies the impact of integrating environmental actions at the level of tourism industries, focusing on the tourism sector in Morocco. It examines the impact of integrating environmental processes on the management of these industries and on team cohesion. The paper identifies the concepts of environmental management and team cohesion. To juxtapose the literature with the field, we conducted a field survey in Morocco's oldest region, Fez-Meknes, where tourism is important and local industries took advantage of the absence of tourists during the COVID-19 period to implement several environmental actions. By implementing these processes, tourist industries can improve their brand image and make considerable savings. On the other hand, they need to consider the impact of these new practices on team cohesion. Our article will attempt to examine the relationship between the implementation of environmental initiatives and the cohesion of players in the tourism industries of the Fez-Meknes region.
“Bird in a Cage”: Traditions and Customs That Restrict Women’s Rights in the Kazakh Context as a Research Topic
Authors: Absatar Aruzhan , Alishayeva Botakoz
Published: January 2024

Kazakh traditional wisdom says “Kaytyp kelgen kyz zhaman” - a girl who returns to her parental home after marriage is a disgrace to the family. According to a women’s rights organization, up to 5,000 bride kidnapping acts occur annually in contemporary Kazakhstan. The authors would like to approach this socio-cultural phenomenon through considering the current situation of women and their rights in Kazakhstan. The article examines how outdated traditions and customs violate women’s’ personal boundaries and rights in Kazakhstan. Its main purpose is to attract the attention of the reader and potential researcher and to familiarize them with the topic (a specific form of violence against women), research methods, and research challenges. Until September 2019, there was no special legislation in Kazakhstan aimed at combating domestic violence. However, with the adoption of the Law “On the Prevention of Domestic Violence and the Protection of Victims of Domestic Violence” in September 2019, Kazakhstan introduced institutional measures to prevent and punish domestic violence. Nevertheless, people continue to follow their traditional customs, rather than live in accordance with new legislation.

Use of L1 in Language Teaching: Does the Practicum Experience Change EFL Student Teachers' Views?
Authors: KOCAMAN Serhat , YILDIRIM Rana
Published: January 2024

The use of the mother tongue in language teaching is a long-standing debate that cannot be resolved. While some advocate for the use of the mother tongue (L1), others believe that the use of the mother tongue impedes and adversely impacts foreign language learning. The present study aims to determine whether practicum experience has an impact on ELT student teachers' opinions about the use of the mother tongue in language teaching. This study employed a mixed-methods approach with a questionnaire conducted with 52 student teachers and interviews conducted with 9 participants. The findings of the study indicated that while participants' favorable opinions about L1 use had more than doubled, their unfavorable opinions fell by a factor of three. This occurrence demonstrates unequivocally that ELT student teachers' opinions about the use of L1 changed positively during their practicum experience. This study also seeks to investigate the factors that influence student teachers' opinions about the use of L1 during their practicum experience. The real classroom environment and experience, students' short attention spans, classroom management issues in schools such as crowded classrooms, seating arrangement, and short lesson time, the pressure of the parents and administration as well as students' English proficiency level and interest, are the factors that influence student teachers' opinions about the use of L1. These findings highlighted that student teachers must be trained that using one's mother tongue is not a sin or an ineffective technique, but it conversely may be a valuable instructional instrument for language teaching if it is employed appropriately and efficiently.

Published: January 2024

The use of synthetic pesticides has come under scrutiny, and there has been a subsequent shift toward the investigation of alternative methods for the treatment of plant diseases. One notable advancement in this field is the utilization of porous silicon (PS) powder as a sustainable antifungal agent. The synthesis of PS nanoparticle (PS-NP) powder was carried out using the environmentally friendly ultrasonication process. X-ray powder diffraction, Fourier transform infrared spectroscopy, Raman spectroscopy, UV-VIS absorbance, and photoluminescence were some of the methods used to characterize PS-NPs. The different characterization methods revealed the formation of a nanocrystalline structure possessing a cubic Si crystalline quality. The crystal size of PS-NPs, as determined from X-ray diffractometer data, ranges from 36.67 to 52.33 nm. The obtained PS has a high band gap of 3.85 eV and presents a photoluminescence peak at 703 nm. The antifungal activity of the synthesized PS-NPs was assessed against three molecularly characterized fungi, namely Rhizoctonia solani, Fusarium oxysporum, and Botrytis cinerea, which were obtained from tomato plants. The concentration of PS-NPs at 75 µg/mL exhibited the highest enhancement in growth inhibition percentages as compared to the control group. R. solani had the highest inhibition percentage of 82.96%. In conclusion, the encouraging structural properties and antimicrobial capabilities of PS-NPs pave the way for their application across diverse technological industries. To the best of our knowledge, this is the first in vitro study of PS-NPs to evaluate their fungal control efficiency.
The rise of anti-vaccination legislation in two Midwestern US states: Implications for politics, policy, and society
Authors: Viskupič Filip , Liebl Zachary , Wiltse David L.
Published: January 2024

During the COVID-19 pandemic in the United States, vaccination became a contested issue between politicians at both national and state levels as well as among the public, which became increasingly polarized over this matter. Across the country, a large number of bills were proposed in state legislatures that had the potential to reduce vaccination rates. This short commentary mapped the growth of anti-vaccination legislation in two Midwestern states: South Dakota and Minnesota. We documented the increased volume and scope of anti-vaccination bills and discussed the implications for politics, health, and society. More specifically, it is likely that similar anti-vaccination bills will be proposed in future legislative sessions, which will impose further challenges on public health officials seeking to restore the public’s trust in vaccines.

There’s No Riot Going on – Social Changes from Inside Out. Discourses Surrounding Pop Culture, Authenticity, and Forms of Life in the School Context in the German-speaking Part of Switzerland around 1968
Authors: Bascio Tomas
Published: January 2024

This article shows that social change at the end of the 1960s cannot be understood only in terms of large protest movements, but also on a small scale, as in the case studies analysed here, where the mostly unspoken “moral force of the ideal of authenticity” (Taylor, 1991, p. 17) is expressed by a wide variety of actors. Using two case studies from the school context and with pop culture references, the paper examines how the rebellious practices often described as typical of teenagers around 1968 were present not only among adolescents, but also among young adults – and among young teachers. The boundaries and transitions between young and old, between rejection and acceptance of different practices and forms of life (Jaeggi, 2014) seem to be fluid. Practices in the school context and the forms of life of young people are not always clearly distinguishable from the forms of life of young adults. Forms of life and everyday practices – based on insignia from music, from the world of comics, from fashion – were just as influential for the individual as loud protest movements against the “establishment”.
The Supervision of Schools and the Language of the Czechoslovak Administration. On the Example of School Committees in the Bilingual Moravia
Authors: Puš Ivan
Published: January 2024

Based primarily on printed sources this study examines the building process of educational sector in the first years of Czechoslovakia, with a special emphasis on the issue of the supervisory bodies. Especially primary schools were considered by the so-called nationalist activists, both before and after 1918, strategic for building of the national education. School boards and then school committees played besides others an important role in the school enrolment, a key factor in the rise or fall of individual schools and language communities. Therefore, the process of creation of the school committees in the year 1921 is researched in particular. After the dissolution of the monarchy, a new organization of the school authorities and schools went hand in hand with a new language of the Czechoslovak administration. New laws, role of school boards and later committees, communication between them and teachers from primary schools are researched as well. Through the stenographic records of the Czechoslovak National Assembly and through other sources, the aforementioned points are analysed, on the example of the ethnically or linguistically mixed area of the former Crown land Moravia. The interests of the Czech nationalist activists clashed there with interests of the German nationalist activists. The Czech and German district school boards, as the supervision authorities, were abolished and new school committees were to be established instead. In the linguistically mixed regions they remained separated, which brought political disputes. At the same time, the daily agenda of schools, teachers and pupils’ demands could not be hindered. Ministry of Education and National Enlightenment called for speeding up the administrative steps.

Due to its strong photocatalytic activity, chemical stability, resistance to chemical and optical corrosion, and non-toxic qualities, TiO2 has received a lot of attention as a significant semiconductor material. One of the main areas of research in the field of photocatalysis has always been the system made of ZnO, another significant semiconductor, which has stronger physical and chemical characteristics and photocatalytic activity than TiO2 and ZnO alone.The performance of the photocatalysts can be optimized by adjusting the ratio of the components in the complexes. It was found that the catalytic activity of the particulate ZnO nano photocatalysts could be improved by trace TiO2 addition and high TiO2 concentration in the complex, with higher degradation efficiency for methyl orange under simulated solar illumination. The enhanced performance was attributed to the high photogenerated electron-hole separation rate caused by the increased surface oxygen vacancy defects and the enhanced interfacial charge transfer of the pluralistic heterojunction structure. In addition, there is a certain selectivity of ZnO and TiO2 for the photocatalytic degradation of methylene blue and methyl orange, which is related to the charged nature of the catalyst surface and the ionic nature of the pollutant molecules. The inhibitor studies revealed that the degradation reactions of methylene blue and methyl orange involved the active species hydroxyl radicals, superoxide radicals, and photogenerated holes formed on the catalyst surface, with superoxide radicals dominating the methyl orange reaction. The produced photocatalysts' great stability was validated by cycling experiments. Further research on the impact of catalyst dosage and pH of the contaminant solution on the photocatalytic performance of the catalysts revealed that an increase in catalyst dosage resulted in a greater number of active sites for contaminant molecules and incident light, which increased the efficiency of contaminant degradation. In an alkaline environment, the efficiency of the catalyst for photodegradation of pollutants was significantly increased due to the high concentration of strongly oxidizing hydroxyl radicals contained in the alkaline solution.

Published: January 2024

Objectives: This study aimed to determine the acceptability of coronavirus disease 2019 (COVID-19) vaccines and adherence to the preventive protocol among pregnant antenatal attendees in Niger Foundations Hospital Enugu, South-Eastern Nigeria. Materials and Methods: Using a cross-sectional descriptive survey and in-depth interviews, we conducted a mixed method study from June to December 2021. We administered a structured questionnaire to 210 pregnant women to assess their knowledge and adherence to COVID-19 guidelines and interviewed 25 individuals. Quantitative and qualitative data were analyzed using SPSS v.28 and thematic analysis, respectively. Results: The participants’ age range was 20-43 years, with a mean of 29.9 (4.8) years. Most individuals (81.9%) had a university degree, 40.5% were skilled workers, and 73.3% had parity 0-1. They identified close contact (87.1%), respiratory distress (96.2%), and handwashing with soap (96.2%) as the commonest mode of transmission, symptom, and preventive strategy of COVID-19, respectively. Older women and individuals with higher parity had lower knowledge and adherence to COVID-19 precautions. Most participants rejected the vaccines due to fear of the side effects on themselves and the fetus. Conclusions: Although there was good adherence to COVID-19 protocols among the pregnant women in this study, vaccine acceptance/uptake rate was low. Education on vaccine advantages and correction of conspiracy theories are recommended.
Cesarean Scar Pregnancy: A Tertiary Care Center Experience
Authors: Ghazali Sarah M
Published: January 2024

Objectives: To describe the management and treatment outcomes of cesarean scar pregnancies diagnosed in a tertiary care center. Methods: This study retrospectively described all cases of cesarean scar pregnancy diagnosed and managed at a tertiary care center over a 3-year period. Maternal demographics, clinical presentation, treatment methods, and outcomes were all included in the analysis. Results: uring the study period, 5 cases of cesarean scar pregnancy were diagnosed and managed. The median gestational age at diagnosis was 8 weeks, and all fetuses had positive cardiac activity. All cases were initially treated with systemic intramuscular (IM) methotrexate (MTX), but only one case responded well due to fetal bradycardia present prior to treatment. One patient received further management with transvaginal intracardiac potassium chloride (KCL) injection, which resulted in maternal sepsis, hemorrhage, and ICU admission. The other 3 cases were managed by transabdominal intra-gestational sac MTX +/- KCL and showed good clinical response. Two of these cases required an interval dilation & curettage (D&C) due to persistent vaginal spotting with no complications. Conclusions: It is recommended to avoid using systemic IM MTX as the first-line treatment for scar pregnancy unless the pregnancy is failing or non-viable. Intra-gestational sac treatment may cause persistent retained products of conception, leading to bothersome vaginal spotting. An interval ultrasound guided D&C appears to be safe for managing this complication, but the exact interval needs to be determined through further studies. Sepsis is a rare complication of invasive medical treatment, and close surveillance is advised.

A peri-implant femoral fracture (PIFF) is defined as a femoral fracture in the presence of a pre-existing non-prosthetic implant. Classification systems, treatment guidelines and fixation strategies exist for peri-prosthetic fractures, but there is no standard of care regarding PIFFs.

The aim of the Peri-Implant Spanish Consensus (aka PISCO) investigators is to reach an agreement regarding current practices for management of PIFFs and to propose four main principles to assess surgical treatment and prevention of these fractures.

This consensus review was conducted according to the Delphi method. Twenty-two expert orthopaedic trauma surgeons performed the consensus and the definitive statements were approved unanimously.

Biological fixation principles must be utilized in the surgical treatment of peri-implant femur fractures, which include closed or minimally invasive reduction techniques. The osteosynthesis must protect the entire bone.

Gaps between two implants should be avoided. If implant overlap is not possible to achieve, then spanning inter-implant fixation systems must be used, especially in osteoporotic bone.

Previous implants should be retained during surgical treatment of peri-implant femur fractures. Only those implants that would interfere with current fixation goals should be removed.

If the previous implant is in the femoral neck region, then femoral neck protection must be maintained when treating the peri-implant fracture, even if the neck fracture has already healed.
Manifestation’s Minimization of Social Exclusion In Ukraine Based on Overcoming Dysfunctionality of the Socio-Economic Systems Regulation

Published: January 2024

Achievement of balanced development of socio-economic systems of different levels lies in the plane of effective regulation of processes arising as a result of the action of various factors associated with negative phenomena of both an economic and social nature. Ensuring effective regulatory influence on the part of state and regional authorities is a guarantee of sustainable socio-economic development of the state and its regions, reducing interregional disparities, increasing the investment attractiveness of territories, preventing complications on a political, economic, and interethnic basis. This, in turn, is the basis of national state policy, as well as regional policy as its integral component. The modern dynamism of socio-economic development poses new challenges to the state due to the need to counteract the negative effects of the incessant transformations. We consider the strengthening of inequality and processes of social polarization caused by changes in the social structure of society to be the most striking of them. These changes have resulted today in the spread of such a negative social phenomenon as social exclusion. The problem of social exclusion in Ukraine and its regions is primarily related to the dysfunctionality of the processes of regulation of the main spheres of ensuring citizens' livelihoods, in particular, the spheres of employment, wages, social guarantees and the availability of social services. In addition, the significant risk for individuals to fall into the category of socially excluded today is caused by the presence of other destabilizing factors of an economic nature. These factors include the presence of significant imbalances in the labor market, in particular, a high level of unemployment and a reduction in the number of jobs, a significant level of poverty, including among the working population, the risk of not getting a job in accordance with the acquired qualification level and other factors that are especially threatening for the preservation and development of the human potential of the state.

Published: January 2024

In modern conditions, when market factors have gained even more influence, and the behavior of business structures has become less predictable, companies have to rethink their activities and focus on using the concept of marketing as a management tool. The growth of competition has created conditions for the active use of a marketing approach in order to solve management and sales tasks and increase competitive advantages. The chronology of the development of marketing, which includes 6 main stages, was studied. The main approaches to the interpretation of the concept of “marketing” are analyzed, among which the following are distinguished: philosophical, managerial, organizational, functional, essential, valuable and institutional. Marketing is an activity aimed to generate demand, promote the company’s products/services, attract the attention of consumers and satisfy their needs through the purchase process. The main elements of the marketing strategy were characterized, namely: analysis of the promotion market, research of the target audience, definition of competitors, analysis of the current state of the company, definition of development goals, positioning and development of advertising promotion. The object of the study was the IT company “Uvik Software”, which has been operating on the market since 2013 and specializes in IT services. The current state of marketing activities of the IT company “Uvik Software” was analyzed. A marketing strategy was developed for the IT company “Uvik Software”, in particular, a market analysis was carried out, an analysis of competitors and their products, an analysis of the target audience (a portrait of the target audience was drawn up according to the following parameters: industry, location, financial condition, number of employees and necessary services), carried out SWOT analysis of the company, development goals (business goals, marketing goals, communication goals and media goals), positioning and advertising promotion advice are given.

Optimizing Segregated Waste Collection Routes as a Decision-Making Problem in the Municipal Solid Waste Management System in Small Town
Authors: Ilasz Dominika , Abramczyk Izabela , Gdowska Katarzyna
Published: January 2024

Routing vehicles is a generic decision-making problem of strategic management in any business serving customers in distributed locations with a limited fleet including municipal solid waste collection. This paper introduces an approach tailored for optimizing waste collection routes in small towns and rural areas where dead-end streets are typical in the road network. Leveraging the Traveling Salesperson Problem (TSP), the approach employs optimal route determination taking advantage of the specific character of a road network with many dead-end streets. The service area for waste collection was aggregated, so the graph representing the map results in a relatively small data instance. This facilitated the application of the exact method, i.e. Mixed-Integer Programming using the OpenSolver tool in Excel. Conducted in collaboration with a municipal agency in southeastern Poland, this study outlines a comprehensive methodology, emphasizing the reduction of complex dead-end streets into singular nodes within the graph for effective route optimization. A comprehensive methodology is outlined alongside the solutions attained. Computational experiments focused on minimizing total travel distance during waste collection operations, demonstrating the methodology's success. Beyond efficiency gains, optimized routes hold potential for significant environmental impact reduction. The reduced travel distances result in decreased fuel consumption and emissions, aligning with sustainability goals. Developing an Excel-based decision support tool for municipal solid waste management is a significant contribution, particularly for decision-makers less familiar with Operations Research. The tool's compatibility within the spreadsheet environment streamlines waste management processes for municipal units, enhancing decision-making efficiency in optimizing waste collection routes.

In today's globalized and interconnected world, the impact of global crises poses increasing risks to the economic situation of each country in particular. The study of cross-border cooperation in the context of current crisis processes allows us to identify new risks and ways to minimize them. The purpose of the study is to analyze ways to optimize the management of cross-border projects in the context of the impact of global economic crises. Scenario planning, SWOT analysis, statistical and mathematical research methods are used in the course of the study. The article discusses the peculiarities of managing cross-border projects on the example of the Precarpathian National University in the context of the impact of global economic crises. Using the example of the university, the author analyzes the implementation of cross-border projects for the period of 2020-2022, which occurred during two crises. The first global economic crisis is caused by the COVID-19 pandemic and the second regional crisis is caused by the war in Ukraine. The risks faced by the grantee in implementing international programs are identified. The study analyzed four different cross-border projects, which made it possible to assess all the risks in more detail and identify existing problems. For a detailed analysis, the medium-sized PrePOD project was selected, which operated from 2020 to 2022 and received an average amount of funding. The strengths and weaknesses of cross-border cooperation were assessed. The study pays special attention to the role of the Precarpathian National University, emphasizing the need for financial risk management, effective communication, compliance with the law, and adaptation of national legislation to European standards. The paper formulates strategies for improving the management of cross-border projects in the context of global crises, and proposes to create research centers to improve the management of grant activities. It has been determined that flexibility and communication are the international factors that can reduce the impact of crisis processes on the implementation of international cooperation.
Theoretical Preconditions to Classify Soft Law as Part of the Legal System: The Case of Aviation Law
Authors: Stonkus Saulius
Published: January 2024

This paper examines the theoretical preconditions for classifying aviation soft law as part of the legal system by distinguishing the essential characteristics of this phenomenon and analysing them within the context of different perspectives of legal understanding, presupposed by the competing binary and continuum (relative or gradual normativity) perceptions of Law, as well as the Theory of Functional Normativity.
Canadian Codes of Medical Ethics as a Source of Law
Authors: Lytvynenko Anatoliy A. , Petlina Tetiana V.
Published: January 2024

The article discusses the codes of medical ethics which are adopted in Canada. These acts are not ‘classical’ normative-legal acts, since they are adopted not by legislative bodies, but rather by medical associations, and are aimed at providing rules on the professional conduct of physicians and auxiliary medical personnel; occasionally, they also feature the rules concerning the rights and duties of patients. The article’s sources include the codes of medical ethics adopted in Canada, Canadian court judgments, and academic literature.
The Functions of European Criminal Law and the Criminalization Discourse: between the Harm Principle and the Protection of Legal Goods
Authors: Cardoso Raquel

Agenesis of the sacrum, lumbar and thoracic vertebrae, is a congenital malformation, associated with other complex genetic syndromes. Sacral agenesis is the partial, or total absence of lower vertebral bodies, can occur isolated or in association with other syndromes including spinal cord anomaly such as (VACTREL syndrome, and Currarino triad).1 The incidence of sacral agenesis is 1/50 000 in general population but is 200 times more frequent in infants of diabetic mothers.2 Usually, children with sacral agenesis have dysmorphic features; to note that around 20% of the cases are undetected until the age of 3- 4 years old and many are diagnosed after unsuccessful toilet training. One of the rarest congenital disorders is “Caudal regression syndrome” that affects the distal spinal segments and result in sequelae on the development of the spinal cord. This syndrome has a low incidence in general population, it is characterized by lower limbs deformities with sensory and motor loss, along with neurogenic bladder however, intelligence is conserved. The exact etiology is vague, yet there is an obvious relation with maternal diabetes. Also, the true cause is still unknown, some theories, state the role of genetic factors, hypoperfusion, and teratogens in the pathogenesis of this syndrome. Treatment is mostly supportive, and multidisciplinary. Prenatal imaging studies allow for consistent detection and diagnosis. The physical exam and the diagnostic test required in the newborn period help in the detection of probable complications and establishing a prognosis. We present a clinical case of a girl with a diagnosis of Caudal regression syndrome, describing the workup and management of this patient.

There is significant evidence of the positive health impacts of probiotics in humans and animals, which is why their application has potentially increased in recent years, especially in the food and pharmaceutical industry. In this context, their inhibitory potential has also been explored as a strategy to ensure food safety and biocontrol of pathogens relevant to public health. The objective of the research was to determine the inhibitory effect of microencapsulated Lactobacillus lactis on Salmonella typhimurium and its viability under simulated gastrointestinal conditions. To characterize the lactic strain, a preliminary experimentation was carried out, and based on this information, four inhibition methods were proposed, with different concentrations of the probiotic bacterial supernatant, then the lactic strain was subjected to simulated gastrointestinal conditions, with different pH levels and % of bile and bile salts, and finally the in vitro adhesion assay was performed. Inhibition halos greater than 2 mm (PADS) were found, optimal viability values were observed (3.0x108UFC/mL), adhesion capacity of the strain in cell cultures was evidenced.

Досліджено трансформаційні властивості двох класів узагальнених рівнянь Кортевега-де Фріза з коефіцієнтами, що залежать від часової змінної, а також продемонстровано ефективність методу еквівалентності для побудови точних розв’язків таких рівнянь. Зокрема, знайдено групоїди еквівалентності обох класів рівнянь і доведено, що обидва класи є нормалізованими. Знайдено критерій звідності рівнянь з одного з досліджуваних класів зі змінними коефіцієнтами до стандартного модифікованого рівняння Кортевега-де Фріза, а для другого класу рівнянь встановлено повну подібність до класичного рівняння Кортевега-де Фріза. Показано, що метод еквівалентності знаходження точних розв’язків є більш ефективним для таких класів рівнянь, ніж методи, що застосовувались іншими авторами. В результаті отримано формули для генерації точних розв’язків узагальнених рівнянь Кортевега–де Фріза зі змінними коефіцієнтами та наведено приклади побудови точних розв’язків за допомогою цих формул.
Про побудову керування, що глобально стабілізує рух одноланкового маніпулятора із нелінійно пружним зчленуванням в околі залежної від часу траєкторії
Authors: Хорошун А.С.
Published: January 2024

Отримано закон обертання електродвигуна, який забезпечує глобальну стабілізацію руху моделі одноланкового маніпулятора із пружним зчленуванням в околі заданої залежної від часу траєкторії. Пружність зчленування моделюється торсіонною пружиною, сила пружності якої вважається нелінійно залежною від зміщення. Цей факт унеможливлює застосування звичайного підходу (розрахованого на лінійність сили пружності) і значно ускладнює задачу побудови керування. Проте, застосовуючи техніку DSC (Dynamic Surface Control), отримано бажане керування. Специфічний вибір параметрів керування і констант фільтрів дозволяє уникнути зростання порядку допоміжної системи, а також явища значного ускладнення вигляду як допоміжної системи диференціальних рівнянь, так і закону керування, тобто явища “explosion of complexity”. Зниження порядку системи диференціальних рівнянь та спрощення її вигляду дозволили в даному випадку отримати в явному вигляді відповідну функцію Ляпунова та з її допомогою довести, що запропоноване керування вирішує поставлену задачу керування.
