Authors: Mayorov Vladimir Ivanovich , Voloshin Petr Valerievich , Polyakova Svetlana Vladimirovna , Dunaeva Olga Nikolaevna
Published: June 2024

In world practice, an innovative search for the most effective approaches and methods in ensuring road safety is continuously carried out. This process is closely interconnected with the level of socio-economic development of the state, the development of technology and technology, the growth of motorization of the population and the development of social institutions of society. At present, a risk-oriented approach is becoming more widespread in public administration in this area. It is on the basis of this approach that Russia has adopted the «Strategy for road safety in the Russian Federation for 2018-2024», which includes the following risks: 1) uncontrolled growth of motorization; 2) the deepening gap between the rate of motorization and the rate of development of the road network; 3) the existing priority of economic results of economic activity over the principle of ensuring the safety of life and health of citizens participating in road traffic; 4) decrease in the average age of the driver's staff; 5) underestimation of the role of civil society institutions and the media in shaping law-abiding behavior of road users; 6) the application of priority measures that are not timely provided by the regulatory and methodological framework in the area under consideration. The main research results: 1) substantiated the substantive characteristics of the risks specified in the Strategy, based on domestic and foreign experience; 2) it is noted that despite the obvious significance of the listed risks, the Strategy does not indicate the criteria for their selection, therefore, formally, they are more in line with the direction, which can create difficulties in their differentiated study; 3) the proposal to expand the scope of «age» risks to include the social-age group of «elderly» drivers is substantiated, since the life expectancy of Russian citizens is increasing, the boundaries of the retirement age are pushed back, people remain active for a long time, including as road users. It is concluded that the effectiveness of the application of a risk-oriented approach in the field of road safety is associated with the creation of a clear risk management mechanism, based on an internally uniform and agreed scientific and methodological base, which is currently being actively developed in Russia.

Published: June 2024

In this paper, we provided new methods that improve modeling flexibility of probability distributions. The methods focus on the construction of kernels for possible development of new probability models from (root) variable components or arbitrary functions. These approaches are further grouped into two different categories including construction of kernels from existing probability functions or directly using mathematical deterministic functions. The Direct substitution approach, homogeneous and inhomogeneous interaction methods are captured under kernel development from probabilistic functions. Two distributions namely, Lindley-Sine Distribution (LSD) and Alpha Lindley Distribution (ALD) were developed from the variable component of the Lindley distribution. More so, the combinations of normal and arcsine distribution, and Gumbel and exponential distributions birthed the Double Censored Normal-ArcSine Distribution (DCNAD) and Left Censored Gumbel-Exponential Distribution (LCGED) respectively. Interesting unconventional trends including decreasing sinusoidal, bathtub, triangular and circular trends realized from these developments validates the relevance of the approaches in probability forecasting. Finally, the asymptotic stability of the parameters of the derived distributions was established through simulation study.

Authors: Purnomo Agus , Syafrianita Syafrianita
Published: June 2024

This study endeavors to evaluate the effectiveness of green distribution and green supply chain practices at PT Bio Farma (Persero) in relation to polio vaccine products. The ultimate objective is to establish and attain future green distribution targets. The research methodology utilizes the Green Supply Chain Operations Reference (Green SCOR) model and the Analytical Hierarchy Process (AHP) to analyze the production and distribution data of polio vaccine (OPV) and inactivated polio vaccine (IPV) products from January to December 2023. The performance values for each key component of Green Distribution and Green Supply Chain are as follows: Plan = 22.9, Source = 16.60, Make = 21.53, Deliver = 11.24, and Return = 7.08. The total performance value for Green Distribution and Green Supply Chain is 79.41. According to APICS standards, the performance of Green Distribution and Green Supply Chain is rated as “Good”. Future performance improvements will focus on supply chain and collaborative planning, establishing long-term partnerships with suppliers and customers, optimizing environmentally friendly transportation, and developing the enterprise information system. Our study proposes that the distribution and logistics managers at PT Bio Farma should persistently monitor and assess their operations to enhance the efficiency of their green distribution and green supply chains. By doing so, they can ensure the successful attainment of performance objectives for disseminating the polio vaccine in Indonesia. This research presents a significant advancement by incorporating the Green SCOR framework into the specific domain of polio vaccines, emphasizing sustainability and environmental efficiency. This approach paves the way for new avenues of investigation in green supply chain research and offers a novel viewpoint on how the pharmaceutical industry, specifically vaccine distribution, can utilize sustainable practices to enhance their operations while mitigating environmental ramifications.
A hybrid genetic-simulated annealing algorithm for multiple traveling salesman problems
Authors: Smaili F.
Published: June 2024

The Multiple Traveling Salesman Problem (MTSP) was able to model and solve various theoretical and real-life applications. This problem is one of the many difficult issues that have no perfect solution yet. In this paper, on the one hand genetic algorithms with different combinations of operators and simulated annealing were used to solve the MTSP. On the other hand, the genetic algorithm with the combination of operators that gave the best solutions of the MTSP was hybridized with a Simulated Annealing algorithm. The simulation results showed that the hybrid algorithm significantly outperforms most of the comparable methods in obtaining the best-fitness solutions compared to the other methods in most of the test cases. In addition, by scaling the fitness function according to the amplitude of tours, it was obvious that the non-dominated front obtained by the hybrid algorithm was better than the non-dominated front obtained by the other algorithms.

Published: June 2024

Saudi Arabia's Vision 2030 seeks to transition towards a cashless society and increase non-cash transactions to 70% by 2025. The COVID-19 pandemic has further accelerated cashless activities in Saudi Arabia, with e-payments increasing by 75% in the past year. This study explores consumer behavior towards using e-wallets in the post-COVID-19 era by employing the extended Technology Acceptance Model (TAM). The results of an online survey conducted among 303 Saudi citizens were analyzed using SPSS. This study examines the correlation coefficients between the variables and conducts an ANOVA to determine the influence of all variables on consumer behavior towards e-wallets in Saudi Arabia post-COVID-19. The findings indicate that consumer behavior is positively influenced by perceived usefulness, perceived ease of use, lifestyle compatibility, and traceability, whereas cost does not significantly impact the use of e-wallets. Additionally, the results show that approximately 28.1% of the respondents used e-wallet services due to the pandemic. This study adds to the literature by expanding on previous work on the topic and providing detailed insights into the factors of e-wallet acceptability in Saudi Arabia.

Published: June 2024

Manufacturing companies constantly strive to produce products that promote better competitiveness. In addition, the current business environment requires manufacturing companies to adopt environmentally friendly concepts, which have become a global customer concern. Therefore, companies must inevitably meet environmental protection requirements through ecologically friendly processes and products. Meanwhile, environmentally friendly adoption requires a capital-intensive investment, which doubts the management regarding the investment return. Hence, top management commitment is highly needed to maintain eco-friendly products and contribute to the company's performance. This study examines the role of top management commitment to operational performance through adopting information technology, supply chain integration, and green supply chain management. This study surveyed manufacturing companies that have implemented ISO 14000, as many as 73 companies with criteria of having more than 100 employees. Data is collected using questionnaires directly and online with Google Forms. The results of data processing analysis found that top management commitment influences information technology adoption with a priority scale to maintain competitiveness and strategies that increase competitiveness. Top management commitment through information technology can improve supply chain integration and green supply chain management. In addition, supply chain integration improves green supply chain management and operational performance. Implement environmental-friendly measures by involving external partners to impact operational performance. The results of this study contribute to enriching supply chain management theory by significantly adopting green supply chain management to improve sustainable development and performance. It also makes a practical contribution by providing insight for practitioners to generate added value for customers.

Quantitative Analysis of Urban Transformation using Remote Sensing Data and Machine Learning Approach
Authors: Nita Nimbarte
Published: June 2024

Urban areas are always changing, which makes it hard for planners and lawmakers to keep an eye on growth and handle it well. Combining remote sensing data with machine learning methods is a new way that this study suggests to look at how cities are changing quantitatively. We get a lot of spatial and spectral information from high-resolution satellite images that help us describe urban areas in more detail than ever before. As part of our method, we preprocess satellite images to pull out useful information like land cover, land use, and the shape of cities. Then, these features are fed into machine learning methods like convolutional neural networks (CNNs) and support vector machines (SVMs) to sort and look at how cities have changed over time. We show that our method works by doing a lot of tests and experiments to make sure it can correctly find and measure urban transformation processes, such as population growth, changes in land use, and infrastructure development. We also look at how this method could be used in different urban planning and management situations, like finding places that are likely to grow quickly, figuring out what effect policy changes will have, and guessing how cities will grow in the future. To look at how cities are changing, satellite pictures are used with both guided and unstructured classification methods. For algorithm research, the software tool Arc GIS Pro is used. As more people move to cities, the Nagpur city area has changed a lot. From 2005 to 2023, development went from 7% to 30%. This method can be used to keep an eye on changes in land use, city growth, and the natural impacts of city growth.

Authors: Hendra Oke , Sadiatmi Rini , Hidayat Zulham
Published: June 2024

The governance network serves as a crucial conceptual framework to be applied within the context of air transportation policy, particularly concerning aviation safety. This study aims to conduct a systematic literature review of prior research focusing on governance networks in the aviation safety sector and to elaborate on the existing knowledge landscape, identify prevailing research gaps, and formulate pertinent implications for future investigations. The review relies on a systematic literature review comprising 67 publications from the Scopus database. The review process adheres to the PRISMA method, wherein data from each article are categorized and documented in worksheet format. This approach facilitates systematic data grouping and subsequent descriptive and thematic analysis. The result from the review reveals a significant body of prior research about governance networks within the aviation context, predominantly in Europe and the United States. Research on networks and governance in the aviation sector has been underway since 2004. However, research explicitly applying the concept of governance network within the aviation context remains somewhat limited. Over 18 years, only 19 relevant articles have been identified. Furthermore, applying network governance concepts in aviation safety contexts is an underexplored area, with only ten articles focusing on this aspect. These findings underscore substantial opportunities for further research in the future.

Authors: Arifiyana Djamilah , Wardani Ratih Kusuma
Published: June 2024

In this study, orange peel was used as an adsorbent to determine the adsorption properties of lead metal. The orange peel used in this study came from waste generated by a fruit juice shop. The mass variation of the adsorbent was studied to determine its effect on the adsorption of lead metal. Mass variations used include 0.25-1.5 gram. The operating conditions used in this study included the preparation of 50 mL of 50 mg/L Lead solution, the pH of the mixture was adjusted to pH 4, the stirring speed was 100 rpm for 180 minutes and at 25℃. The results showed that the highest % adsorption was achieved at an adsorbent mass of 0.75 grams, which was 92.9% (2.5 mg/g), while the highest adsorption capacity was obtained at the use of an adsorbent mass of 0.25 grams (7.27 mg/g). Both the decrease in % adsorption and adsorption capacity that occurred in the use of the mass variation of the adsorbent were mostly caused by the aggregation process.

Authors: Pratiwi Widi Ambar , Nasyanka Anindi Lupita
Published: June 2024

Antibiotics are medications that combat bacterial illnesses. There are several negative health outcomes associated with the current epidemic of antibiotic resistance, including higher rates of illness and death, higher healthcare expenditures, and treatment failures. In 2015, there were an increase of 50 million unnecessary antibiotic prescriptions (Unnescecery prescribing) from 150 million, and this number continues to increase every year. Thus, the number of bacteria that are resistant to antibiotics is increasing. This study aims to determine the extent of public awareness on the utilization of antibiotics in Dusun Blungkan, Sendangrejo village, Lamongan district. The design of this research is descriptive research and data collection using questionnaires with Cronbach's alpha value of 0.83 (>0.60) then the questionnaire is declared reliable that covers 7 domains of knowledge namely understanding antibiotics, antibiotic examples, antibiotics use, dosage, contraindications, side effects, and antibiotic resistance. The results showed that in Dusun Blungkan, Sendangrejo Village, Lamongan District, and Lamongan Province there are 21 (70%) people who are aware of the use of antibiotics. Out of 30 respondents, 21 people (70%) have sufficient knowledge, 7 people (23.3%) have less knowledge, and 2 people (6.7%) have good knowledge. Controlled use of antibiotics can prevent resistance. Therefore, accurate information about the importance of antibiotics and how to use antibiotics properly and correctly is needed, as well as more wisdom in using them to avoid unexpected side effects.
The interdisciplinary approach to the assessment of mechanical pain sensitivity in temporomandibular disorders
Authors: Bordeniuc Gheorghe , Lacusta Victor , Tighineanu Marcela , Cazacu Igor , Fala Valeriu
Published: June 2024

Introduction: Temporomandibular disorders (TMDs) are non-dental orofacial pain conditions with a high prevalence in the general population (5-12%). One of the clinical peculiarities is the fact that TMD is often associated with various changes in mechanical pain sensitivity (MPS) at the level of the structures of the stomatognathic system (temporomandibular joint, masticatory muscles), which has the impact of increasing the difficulties of diagnosing this problem for the clinicians. Objective of the study: to evaluate options for clinical investigation of the expression and spatial distribution of mechanical pain sensitivity (MPS) in temporomandibular disorders. Material and methods: We performed the analysis of the variation in the expression of mechanical pain sensitivity (MPS) based on the data obtained by algometry (thresholds of sensitivity/tolerance to pressure) collected in 55 patients. The investigation was carried out in the projection of acupuncture points ST6 (masseter muscle), ST7 (temporomandibular joint). Data collection was carried out in 2 states (relative rest conditions, operational stress modeling). The investigation of the spatial distribution of mechanical pain sensitivity (MPS) was carried out through pain maps at the level of the masseter muscle (30 patients with temporomandibular disorders and 30 asymptomatic people - control group). Results: In the study, it was identified that the expression of mechanical pain sensitivity (MPS) varies according to the test conditions (relative rest/modeled operational stress), being attested statistically significant reductions at the masseter muscle level (tolerance threshold and sensitivity/tolerance threshold ratio) under stress conditions. This state reveals a hypoalgesia occurring after the stressful event, which reflects the complexity of the mechanisms involved in the pathogenesis and evolution of TMD. The observed spatial distribution of mechanical pain sensitivity (MPS) revealed the importance of using complex synthetic indices, which allow the processing of raw data (sensitivity/tolerance thresholds), including the reflection at the level of MPS heterogeneity/homogeneity. Conclusions: Investigating the particularities of mechanical pain sensitivity at the level of the stomatognathic structure, especially masticatory muscles in temporomandibular disorders, which represent a reliable interdisciplinary approach, which requires investigation in multiple standardized conditions (relative comfort/operational stress modeling), with the evaluation of the sensitivity distribution (pain maps). The integral view of TMD through the prism of MPS aspects provides new clinical evaluation criteria (expression intensity, spatial distribution, heterogeneity).

Published: June 2024

Customer loyalty in various industries is an interesting variable to examine. This is because every industry has different dynamics, features, and components that influence customer behavior. The method used in this study is a qualitative method with systematic bibliographic review analysis using Vosviewer tools. The research data is 100 articles taken from databased Emerald from 2015 to 2024. The results of the bibliometric analysis of this study show that there is still the possibility of research in the field of marketing for areas related to customer loyalty. The results of the network visualisation analysis show that there are still nodes with small sizes that show that research has not been rampant in the areas represented, such as service recovery resilience, customer outcomes, flexibility, and return satisfaction. Analysis on overlay visualization shows research trends related to customer loyalty in the areas of autenticity, authentic experience, potential gain, experience quality, and interaction quality. In terms of density, there are still opportunities to examine social selling activity, mindfulness, customer retention strategies, and ethical behavior. This conclusion also leads to the authors' recommendations for future research related to customer loyalty can lead to areas that are trending and have not been explored much by previous researchers.
Numerical modeling of the effectiveness of recycled aggregates in reinforcing soft soil with granular columns
Authors: Yousfi Mohammed Amin , Guettala Salim , Farik Ali , Hamad Haithem Boughezala
Published: June 2024

In recent years, the civil engineering field has increasingly focused on recycled aggregates due to the dwindling availability of natural aggregates and the high carbon footprint associated with their extraction and use. The use of recycled aggregates aims to decrease energy consumption and lessen the environmental impact caused by construction waste. This study illustrates the value of utilizing recycled aggregate materials for soil reinforcement and demonstrates their efficiency compared to natural aggregates. The research employs several numerical simulations carried out using PLAXIS 3D, a finite element software renowned for its advanced modeling capabilities. These simulations leverage the Mohr-Coulomb failure criteria alongside an elastic-perfectly plastic behavior model to assess the performance of various materials under different conditions. Specifically, the study investigates three types of granular columns—Ordinary Stone Columns (OSC), Sand-Fiber Mix (SFM), and Recycled Aggregate Porous Concrete Piles (RAPP)—to reinforce a unit cell model of soft soil under failure loading scenarios. Detailed analysis reveals that recycled aggregate columns exhibit a significantly higher bearing capacity, showing an improvement of up to three times that of columns made with natural aggregates. This superior performance is attributed to the enhanced mechanical properties and better load distribution capabilities of the recycled aggregates. The results are presented through load-settlement curves, which provide a clear visualization of the effectiveness of each type of granular column. Furthermore, the study highlights the practical implications of using recycled aggregates in soil reinforcement projects.  The substantial improvements in bearing capacity demonstrated by the recycled aggregate columns underscore their potential as a viable and sustainable alternative to natural aggregates in various geotechnical applications.
A disponibilidade de terapeutas ocupacionais no Sistema Único de Saúde para o cuidado após acidente vascular cerebral no município de Marília
Authors: Silva Ana Cristina Cardoso da , Pascoal Raiza Pretel
Published: June 2024

O Acidente Vascular Cerebral (AVC) altera funções sensoriais, motoras e cognitivas, impõe restrições no engajamento em ocupações e impacta a vida social, econômica, espiritual e sexual dos sujeitos. É recomendável que o tratamento pós-AVC seja conduzido por equipe multiprofissional nos vários níveis e serviços de atenção à saúde. Esse estudo objetivou mapear a disponibilidade e a distribuição de terapeutas ocupacionais para a assistência das pessoas que sofreram AVC, nos equipamentos de saúde da Rede de Cuidados à Pessoa com Deficiência (RCPCD) do município de Marília-SP. A primeira e a segunda etapa consistiu, respectivamente, na busca pelos equipamentos da RCPCD e na seleção daqueles que apresentavam o terapeuta ocupacional inserido como parte da equipe, de acordo com informações do Cadastro Nacional de Estabelecimentos de Saúde. Na terceira etapa foi realizado contato com terapeutas ocupacionais desses equipamentos, para informarem se estavam designados para o cuidado das pessoas pós-AVC. A análise dos dados foi conduzida por meio de cálculos de estatística descritiva, sendo quantificados os equipamentos disponíveis e o número de profissionais associados.  Existem 64 equipamentos na RCPCD do município estudado, mas apenas 13 terapeutas ocupacionais para atender a população no pós-AVC, 3 no contexto hospitalar, 7 em centros de reabilitação e 3 distribuídos em Unidades de Saúde da Família. Apesar dos avanços das diretrizes nacionais e dos decretos estabelecidos pela categoria profissional, da criação da RCPCD e da Linha de Cuidados do Adulto com AVC, a disponibilidade de terapeutas ocupacionais ainda é baixa e desigual entre os níveis de atenção. No processo de cuidado da pessoa acometida pelo AVC é inerente o tratamento com terapeuta ocupacional e com outros profissionais da saúde, da educação, do trabalho e da assistência social. Portanto, a escassez de profissionais na RCPCD tende a prejudicar o acesso ao cuidado, o processo de reabilitação e a melhora dos sujeitos.

Published: June 2024

O objetivo desta revisão foi unir informações a respeito dos métodos de determinação da acidez potencial do solo, com foco nos solos do noroeste do Paraná e verificar uma alternativa ao tampão SMP que é tóxico e com potencial cancerígeno. A acidez potencial (H+Al) abrange íons H+, H ligados covalentemente e Al+3 que preferencialmente estão aderidos aos coloides e a matéria orgânica na fase sólida do solo. A metodologia de recomendação de calagem fundamenta-se na H+Al, que possibilita a neutralização de todos os tipos de acidez do solo. A determinação da H+Al pode ser realizada por variados métodos, sendo que os mais demorados e trabalhosos são usados na padronização de métodos mais rápidos. A H+Al tem sido estimada pela solução tampão SMP a partir de equações que correlacionam valores de pH SMP com valores de H+Al obtidos por métodos padrão. Porém, o tampão SMP possui substâncias tóxicas, como o p-nitrofenol e o cromato de potássio, que são cancerígenas e perigosas ao ser humano e ao meio ambiente. Com a recomendação alternativa de usar solução tampão livre de reagentes tóxicos para determinação indireta da H+Al, foi proposto o tampão IPR/UEM para solos do Paraná, apresentando metodologia semelhante ao pH SMP, alterando somente o tampão. Porém, para a região noroeste do Paraná, não houve ajuste significativo, tendo baixa representatividade das amostras e pequena variação dos valores, sendo a equação limitada. Assim, compreende-se a necessidade de pesquisas para calibrar a determinação da H+Al pelo tampão IPR/UEM para solos do noroeste paranaense.

Published: June 2024

A cafeicultura tem histórica relevância geopolítica e econômica no Brasil. O caminho técnico e químico da agricultura industrial passou por um desenvolvimento extraordinário, com a ajuda de enorme aparato, tanto da ciência quanto da indústria química e tecnológica. Entretanto, como consequência da agricultura industrial, ao longo do tempo, notou-se uma redução da renda por unidade de produto produzido, já que o produtor rural usualmente se depara com setores comerciais concentrados ou oligopolizados para a compra de seus insumos e precisa vender seus produtos com preços formados pela livre concorrência. Ademais, é evidente que, baseados em recursos finitos, nutrientes essenciais em algum momento não estarão mais disponíveis para a agricultura convencional. Este trabalho objetivou avaliar o comportamento dos solos, a produção de café e a qualidade de bebida após utilizar dois sistemas de adubação em lavoura cafeeira em Unaí, noroeste do estado de Minas Gerais, no Cerrado Brasileiro. No sistema convencional utilizou-se, como fonte convencionais de nutrientes (FCN), ureia, superfosfato simples e cloreto de potássio. O sistema de adubação utilizando fontes regionais de nutrientes (FRN) utilizou somente adubos produzidos na propriedade agrícola por meio da compostagem conjunta de resíduos orgânicos e rochas moídas. Esses dois sistemas de adubação foram praticados desde o plantio da lavoura até sua primeira colheita. A caracterização dos solos após a aplicação dos fertilizantes foi realizada através da Tecnologia Embrapa de Bioanálise de Solo.

Pricing and replenishment of vegetable commodities is a key step in solving the practical problem of short shelf life in vegetable markets. Our research introduces a nuanced, data-driven approach to optimize replenishment and pricing decisions. At the core of our methodology is the development of a comprehensive model that leverages an enhanced ARIMA, meticulously tailored for distinct vegetable categories. This model is designed to capture the intricate dynamics of market demand and supply fluctuations, enabling precise predictions that guide effective pricing and replenishment strategies. To further refine our model's predictive capabilities, we integrate advanced machine learning techniques, including an optimized XGBoost algorithm, facilitated by a genetic algorithm. This integration not only augments the model's accuracy but also provides a robust framework for analyzing and interpreting complex market data. Through a detailed example analysis, we demonstrate the model's efficacy in forecasting demand and optimizing inventory levels, thereby ensuring that pricing and replenishment actions are both strategic and data-informed.

Photodynamic Therapy (PDT) is a new technology that utilizes the photodynamic effect for disease diagnosis and treatment. Its action is based on the photodynamic effect. It is a kind of photosensitization reaction accompanied by biological effects with the participation of oxygen molecules. The process is that specific wavelength laser irradiation causes the photosensitizer absorbed by the tissue to be excited, and the photosensitizer in the excited state passes the energy to the surrounding oxygen, generating highly reactive singlet oxygen, which undergoes oxidative reaction with neighboring biological macromolecules to produce cytotoxicity, which leads to cellular damage and even death. Current research shows that photodynamic therapy shows great advantages in the treatment of caries, periodontal disease and oral squamous carcinoma. This paper mainly provides a further overview of the current status of research at home and abroad on the application of photodynamic therapy in the treatment of dental diseases in recent years.
Analysis of China-U.S. Exchange Rate based on U.S. Dollar Rate Hike
Authors: Ding Shuyu
Published: June 2024

Based on the data on the exchange rate of RMB against the U.S. dollar, the ARIMA model is used to forecast the exchange rate of RMB against the US dollar in the coming year. The results show that the RMB will continue to depreciate, but there is no possibility of a large depreciation. The rate hike of the Federal Reserve System (FED) is both a challenge and an opportunity for China. In the context of the dollar's continued appreciation to contain domestic inflation, capital outflows will intensify to some extent. At the same time, because of the impact of COVID-19, China's room for policy adjustment has been narrowed. However, the rate rise of the US dollar has accelerated the process of de-dollarization and local currency settlement, providing opportunities for the internationalization of the RMB. China should seize the opportunity of the interest rate hike on the U.S. dollar and introduce reasonable policies to further promote RMB internationalization and China's economic recovery.
Momentum Analysis of Tennis Matches Based on Logistic Regression
Authors: Liu Huanyu
Published: June 2024

The paper first selected ten evaluation indicators such as first-serve scoring rate, double fault rate, and ace rate through a literature review. Then, using the entropy weight method, weights were assigned to each evaluation indicator. The top seven indicators with larger weights were selected as independent variables, with the pointing situation as the dependent variable, to establish a binary logistic regression model. The model achieved an accuracy rate of 94.3%. The paper multiplied the regression-derived weight matrix with the seven indicators, normalizing the resulting values to represent the probability of a player pointing probability. The slope of the pointing probability obtained in this way was defined as momentum. Based on the real-time changes in pointing probability during matches, the article calculated the average momentum for each match. By conducting a chi-square test between the direction (positive or negative) of the average momentum and the corresponding match results, with a significance level less than 0.001, the paper demonstrated a strong correlation between the two, suggesting that match outcomes could be predicted by calculating the average momentum.

Authors: Liu Xiao , Dong Jinxian , Wang Siying
Published: June 2024

This study aims to analyze the average efficiency and thermal power output of a heliostat field. A horizontal coordinate system and a mirror coordinate system are established with the center of the mirror field and the center of each heliostat as the origins, respectively. The study considers various factors including three types of shadowing and blockage scenarios, and spillage efficiency. Using rotation matrices and linear equations, a shadowing and blocking efficiency model is constructed. Combining the principles of concentration, ray tracing method, and geometric theory, the energy flux density is converted into a number of scatter points, and then a model for the various efficiencies and thermal power output of the heliostat field is established. Based on this, an optimization model is created with the objective of maximizing the average annual thermal power output per unit mirror area. A genetic algorithm based on a traversal strategy is used for solving this model, thereby facilitating the design of the parameters for the heliostats and the receiver tower in the heliostat field, improving the average annual thermal power output per unit mirror area, and providing assistance for theoretical research.
