An Efficient Computational System For Defect Prediction through Neural Network And Bio-inspired Algorithms
Authors: KHATIR Abdelwahhab , Oulad Brahim Abdelmoumin , MAGAGNINI Erica
Published: October 2024

Detecting and locating damage is essential in maintaining structural integrity. While Artificial Neural Networks (ANNs) are effective for this purpose, their performance can be significantly improved through advanced optimization techniques. This study introduces a novel approach using the Grasshopper Optimization Algorithm (GOA) to enhance ANN capabilities for predicting defect aluminum plates. The methodology begins by deriving input parameters from natural frequencies, with defect locations as the output. A Finite Element Model (FEM) is used to simulate data by varying defect locations, creating a comprehensive dataset. To validate this approach, experimental data from vibration analyses of plates with different defect locations is collected. We then compare the performance of our GOA-optimized ANN against other metaheuristic algorithms, such as Cuckoo Search Algorithm (CSA), Bat Algorithm (BA), and Firefly Algorithm (FA). Notably, CSA's performance is slightly close to GOA. The results show that our GOA-based method outperforms these traditional algorithms, demonstrating superior accuracy in damage prediction. This advancement holds significant potential for applications in structural integrity monitoring and maintenance.

History Politics in Kosovo: Elites’ Memory and Victims’ Counter-Memory in Public Spaces of the De Facto State (Contradictions of Collective Memory and Memorial Culture)
Authors: Kirchanov M. V.
Published: October 2024

The article examines the development of collective historical memory in Kosovo, a region with contested international political status. The study aims to analyze the memorial policies pursued by Kosovo’s regional political elites, which contribute to the consolidation of the region’s political identity. Additionally, the role and significance of history and perceptions of the past in the discourse shaped by the elites of modern Pristina are explored. Methodologically, the article draws on the interdisciplinary contributions of historiography, particularly the memorial turn, as well as studies that analyze nationalism as a factor in the evolution and transformation of memorial cultures. The novelty of the study lies in its examination of the current stage of historical policy development in Kosovo, a region that is striving for institutionalization and recognition as a nationstate. The article demonstrates that: 1) Kosovo's political elites actively leverage both the real and symbolic potential of collective memory, 2) the region’s historical policy and memorial culture are marked by a high degree of ideologization, and 3) nationalism plays a pivotal role in shaping the main vectors and trajectories of historical policy and memorial culture. The study suggests that the memory policies enacted by the elites tend to blend ethnic and civic Albanian nationalism, characterized by a high level of politicization and ideologization of history. This active use and instrumentalization of historical narratives in public and social spaces transforms collective memory into a tool for memorial confrontation and memory wars.

The use of radiofrequency electromagnetic radiation (RF-EMR) has steadily increased since the 1950s. RF-EMR is used in medicine, industry, household appliances, security and navigation, and especially in wireless elecommunications and animal husbandry. The widespread use of RF-EMR, especially with the introduction of 5G networks, raises concerns about potential adverse effects on human and animal health. The effects and mechanisms of RF-EMR impacts of 5G network frequencies on human and animal health are still unknown orpoorly understood. Current research findings include the biological effects of RF-EMR on genotoxicity, cell proliferation, gene expression, cell signalling, cell membrane function, and the function of immune, ematopoietic, and reproductive systems. Exposure of humans and laboratory animals to RF-EMR emitted from cell phones and many other electronic devices of 4G and older technologies has been shown to have detrimental effects on blood cells and to cause changes in the complete blood count. This depends on the type of organisms exposed, sources,frequency, electric field level and duration of exposure. There is sparse data in the available literature on the effects of RF-EMR on haematology indicators and erythrocyte morphometry in domestic animals. Therefore, the aim of this scientific review is to highlight the effects of RF-EMR on haematology indicators, erythrocyte morphometry, and platelet activation in humans and animals, taking into account the findings on the effects of 5G electromagnetic radiation on these indicators. Considering the ubiquitous electromagnetic pollution, it is important to gain knowledge about the effects of RF-EMR on human and animal health. In addition, it is necessary to determine the effects following in vitro exposure of blood to RF-EMR, especially due to the storage and use of blood and blood products in transfusion medicine.

Authors: Siti Kholijah Siti Kholijah , Sihombing Volvo , Irmayani Deci
Published: October 2024

People's shopping patterns and behaviors continue to develop along with technological advances and lifestyle changes, thus requiring retail business actors, especially supermarkets, to better understand their customers' interests and preferences. In this context, accurate analysis of customer shopping interests is very important to improve customer satisfaction and optimize marketing strategies. One solution that can be implemented to analyze people's shopping interests is the application of the K-Nearest Neighbors algorithm, a simple yet effective nearest neighbor-based classification method for recognizing patterns from existing data. This study aims to apply the K-Nearest Neighbors algorithm to classify people's interest in shopping at supermarkets. This study also evaluates the effectiveness and performance of the algorithm in the context of business decision-making in the retail sector. The research methodology includes collecting data on people's shopping interests, data pre-processing, implementing the K-Nearest Neighbors algorithm, and evaluating model performance using evaluation metrics such as accuracy, precision, recall, and F1-score. The results of this study indicate that the K-Nearest Neighbors algorithm is able to achieve an accuracy of 88%, with precision, recall, and F1-score all reaching 92.86%. These results indicate that the K-Nearest Neighbors model is very effective in classifying people's shopping interests, with a low error rate. The resulting confusion matrix also shows the model's ability to identify customers who are interested in shopping with little prediction error. This study concludes that we can rely on the K-Nearest Neighbors algorithm to analyze people's shopping interests in supermarkets. This model not only shows good performance in classification but also has great potential to be implemented in recommendation systems and customer segmentation in the real world. This study contributes to the development of consumer behavior analysis methods in the retail sector, as well as providing a basis for further research to explore other algorithms or combinations of techniques to improve the accuracy and effectiveness of classification models.

The paper presents the Nuna Cave, as one of the more than 20 documented caves in the karstic environment of Miroč Mt. in eastern Serbia. The wider surroundings encompass the 100 km long gorge of the Danube River (Iron Gates, Djerdap) in the segment where it is entrenched into the Southern Carpathian Mountains, with the Pannonian Basin upstream and the Dacian Basin downstream. The first karst explorations in the area date back to the 19th century, while the majority of them took place in the second part of the 20th century, focusing on speleology, hydrogeology, surface karst morphology, biospeleology and geoarchaeology. Tectonically, Miroč Mt. is an anticlinal structure. On the terrain surface, Upper Jurassic limestones are the dominant lithological component. Typical features of karst morphology are ponors (stream-sinks) along the long lines of contacts between karstic and non‐karstic rocks, approving the status of exemplary contact karst along the whole outline. Nuna Cave is the southernmost ponor of Miroč karst. The length of the cave passages is 135 m, while the denivelation between the highest and lowest point is 17 m (+6, −11). Despite the relatively small length, the cave contains large number of indicators pointing to its geological history, morphogenesis and recent hydrological and morphological processes.
FACTORS AFFECTING MOTOR VEHICLE POLLUTION IN CAPITAL CITIES: A CASE STUDY OF MOSCOW

The change in the volume of emissions from Moscow’s motor transport and its territorial proportions was the result of the combined effect of transformational and inherited factors (path dependency). The key among the inherited factors was the transport network and the radial-ring layout, which leads to low network connectivity. Transformational factors are, first of all, the growth of the number of cars, improvement of fuel, and engine. However, in recent years, on the contrary, the number of cars and the structure of the fleet have become a conservative factor, and the city’s development strategies have focused on the construction and reconstruction of roads, strengthening the connectivity of the network and the development of public transport. The construction of roads and the intensive reconstruction of urban transport arteries significantly improve the nature of traffic, reduce the intensity of congestion, but at the same time create new areas of pollution. Emission reduction is achieved only for light trucks on gasoline and heavy trucks on diesel. The main trend in recent years has been the increasing uniformity of pollution from motor vehicles. New housing construction programs and large-scale projects for the transformation of Moscow districts lead to an increase in the connectivity of the city and, at the same time, to the equalization of the density of motor vehicle pollution. The balance of these factors changes over time (if at the beginning of the post-Soviet period the main factors were inherited, then in recent years these are mainly positive transformational factors) and in space: industrial zones have been preserved only on the outskirts of the city, and railway stations are being moved there; the changing topology of the network has not only increased connectivity, but also created a vacuum effect in the center. Based on field observations and calculations, it has been proven that the construction of new highways and interchanges provides a temporary effect of reducing pollution as a result of the redistribution of traffic but stimulates new traffic and creates new areas of pollution.

Published: October 2024

The advent of the 5G era signifies China’s official entry into the digital economy. This technological shift has attracted countless merchants to the market via e-commerce platforms, seeking to capitalize on new opportunities. Concurrently, it offers a novel avenue for expanding seafood sales channels in China. The interactive and intuitive nature of e-commerce live streaming has subtly but significantly influenced and shaped consumers’ purchasing behaviors. In light of this, this study, based on 330 valid survey responses and grounded in the theories of perceived value and consumer trust, explores the psychological mechanisms affecting consumers in the context of e-commerce live streaming for aquatic products. The findings reveal that: (1) Consumer trust positively impacts purchase intention in the context of live-streamed seafood e-commerce. (2) Perceived entertainment value positively influences consumer purchase intention. (3) Perceived utilitarian value also positively influences consumer purchase intention. This paper contributes theoretically by broadening the application of perceived value theory and enhancing the understanding of consumer behavior concerning seafood. Additionally, it may offer practical insights into the expansion of seafood sales channels and market scale in other countries and regions.

Published: October 2024

This study reports the isolation and characterization of a novel bacteriophage, KG853, specifically targeting Pseudomonas aeruginosa ATCC 27853. Morphological analysis using transmission electron microscopy revealed that bacteriophage KG853 belongs to the Bruynoghevirus genus. The phage demonstrated favorable characteristics for potential therapeutic applications, including a short latent period of 30 minutes and a large burst size of 136 plaque-forming units (PFU) per cell. KG853 exhibited stability across various temperatures and pH values, indicating its robustness under various environmental conditions. Genomic analysis showed that KG853 possesses a circular DNA genome of 45,390 base pairs with a GC content of 52.2%. No lysogenic or virulence genes were detected among the 84 open reading frames annotated in the genome, suggesting its safety for potential therapeutic use. Phylogenetic analysis revealed that phage KG853 is closely related to phage PaP3. Notably, KG853 demonstrated the ability to inhibit the formation of 4-hour biofilms by P. aeruginosa, a critical virulence factor in many infections. Host range analysis showed that KG853 is specific to P. aeruginosa, an important characteristic for targeted therapy. These findings suggest that bacteriophage KG853 represents a promising candidate for combating drug-resistant P. aeruginosa infections. Its specific host range, robust physical characteristics, lack of harmful genes, and anti-biofilm activity make it a potential alternative to conventional antibiotics. Further research is warranted to explore its efficacy in in vivo models and potential clinical applications.

Published: October 2024

Electrofishing is a widely preferred method in freshwater. Freshwater conducts electric current at low levels. Therefore, a relatively high voltage electric current is applied in these waters. In this study, the effects of changes in the structure of the water after the electric current applied to the water on gamete quality and embryo-larvae survival rates were investigated. Water samples were collected from the central region of the tank (N), as well as from the positive (+) and negative (-) poles following the application of an electric current to the well water at 165 volts and 3 mA for durations of 15 and 30 minutes. Sperm kinematic velocity parameters, fertilization and hatching rates were determined to be at the highest level in the group where electric current was applied for 30 minutes and water samples were taken from the middle of the tank, 30 (N), were used (P<0.05). Furthermore, it was observed that the Chemical Oxygen Demand value was one of the values lowest in the groups where sperm motility results were found to be the highest (P<0.05). Regardless of the duration of electric current application, it was found that the dissolved oxygen value of the water samples collected from the positive poles was similar to the control group, but higher than the negative poles. In conclusion, the application of electric current resulted in variations in both the sperm kinematic parameter values and the water parameters among the samples collected from different poles. However, there was no statistically significant difference in fertilization and hatching rates between the groups (P>0.05).

Poesia feminina modernista
Authors: Mendes Karla Renata
Published: October 2024

Julieta Barbara lançou seu único livro de poemas, Dia garimpo, em 1939. Desde então, a poeta foi “apagada” da historiografia oficial, tendo a obra relançada apenas em 2022 (mais de 80 anos depois da primeira edição). Casada com Oswald de Andrade, a autora não teria podido dedicar-se à divulgação de seu livro de estreia, sendo prejudicada por imprevistos e por contingências de ordem prática e pessoal. Dessa forma, amparando-se nos pressupostos revisionistas da crítica feminista, o presente trabalho pretende resgatar a figura de Julieta Barbara, evidenciando as suas qualidades literárias e destacando como sua poesia e, em especial o texto Intitulado “Poesia”, situa-se no contexto modernista com o qual dialoga.

Seismic Response of Open Ground Story Reinforced Concrete Buildings, Considering with Soil-Structure Interaction
Authors: Sagar H  , Naveen R
Published: October 2024

This study investigates the seismic behavior of open-ground story (OGS) reinforced concrete buildings with soil-structure interaction (SSI) using SAP2000. The study mainly focused on mid-rise (8-storey) and low-rise (4-storey) OGS buildings, incorporating different masonry infill materials such as brick, concrete blocks, and autoclaved aerated concrete (AAC) blocks. Selected ground motions from the Bhuj, El Centro, and Chi-Chi earthquakes were utilized to simulate varying seismic intensities and frequency content. Critical parameters such as top-story displacement and inter-story drift are analyzed to assess the structural safety and serviceability of RC buildings. The results demonstrate that both OGS coupled with SSI and masonry infill type significantly affect the displacement and drift, with mid-rise buildings showing more pronounced impacts. Furthermore, ground motion characteristics are critical in producing different response patterns. The study highlights the importance of considering SSI, infill materials, and ground motion characteristics in the design of OGS buildings to enhance earthquake resilience and reduce seismic damage.

In today's digital landscape, video streaming platforms have become the cornerstone of entertainment consumption, reshaping how we engage with media. However, traditional approaches to building these platforms, often relying on monolithic architectures, are struggling to keep pace with the evolving demands of users and the complexities of modern infrastructure. This solution explores a new approach that uses contemporary methods like DevOps and microservices to make video streaming platforms faster, more reliable, and easier to use. The system starts by providing a user interface for streaming content and its entire backend architecture is built using specialized tools and methodologies. The methodologies include containerization using Docker and automation of IT infrastructure using Terraform or AWS CloudFormation which serve as Infrastructure as Code. Lastly, CI/CD pipelines are used to automate all stages of the SDLC life cycle. The application will be deployed on AWS cloud and there will be extensive use of AWS services.

Published: October 2024

This study assessed the effects of canopy structure on tree species diversity and forest structure in OmoBiosphere Reserve. Landsat imagery was used; supervised maximum likelihood classification was used to classify the reserve into two canopy structures (closed and open canopies). Random sampling technique was used to delineate 10 sample plots of 30m x 30m in each canopy type. Tree species with a diameter at breast height (Dbh) ≥10cm were enumerated in each sample plot. Shannon Weiner and Simpson’s indices were used to assess the tree diversity, while diameter and height stratification were used to evaluate the forest structure. Shannon Weiner and Simpson’s indices were 3.507 and 0.953, respectively, in open canopy structure (OCS) and 3.396 and 0.951, respectively, in closed canopy structure (CCS). Species richness and population were higher in OCS (64 and 575, respectively) than in CCS (56 and 531, respectively). Milletia thonningii andStrombosia pustulata were the dominant tree species in OCS and CCS, respectively. The mean Dbhand height in OCS were 40.09cm and 22.86 cm; and 50.21cm and 23.05cm in CCS, respectively. The basal area was 110.01m2/ha in OCS and 207.97m2/ha in CCS. The volume yield per hectare in OCS was 343.35m3/ha and 842.49m3/ha in CCS. The OCS was dominated by younger trees than the CCS. Canopy structure affects tree species richness, population, and diversity, as well as tree attributes.

O dossiê Modernismos no Brasil ao longo do século XX surgiu após o contato estabelecido entre seus organizadores por ocasião da Escola São Paulo de Ciência Avançada: Modernismo e projetos de nação, realizada, com o apoio da FAPESP, no Instituto de Estudos Brasileiros da USP, em Julho de 2023.
A chamada para o dossiê visou “reunir pesquisas que problematiz[ass]em o modernismo como conceito que se fixou para designar o período inaugurado com a Semana de Arte Moderna em 1922. O evento, mais do que um ponto de partida, converteu-se em referência de conformidade e aglutinação de forças que vinham se constituindo entre intelectuais desde a segunda metade da década de 1910. Neste dossiê, não restringimos a interpretação do modernismo ao movimento efetuado pelos paulistas, que teriam transformado os campos artísticos de outros estados brasileiros em meros receptáculos de ideias. Deve ser destacado que essa narrativa hegemônica foi empreendida por parte da elite intelectual nas décadas seguintes ao evento e é fundamental reconhecer que as expressões artísticas, ditas regionais, já haviam incorporado novos temas, linguagens e estéticas em suas produções. Diferenças e divergências no interior dos modernismos foram demonstradas por rupturas e continuidades mais ou menos explícitas como, por exemplo, discordância de opiniões em relação à construção das nacionalidades brasileiras, possibilidade de “deglutir” as influências estrangeiras ou decreto do “jejum” não colonial. Com base nessas provocações iniciais, este dossiê pretende ser um espaço para apresentação de pesquisas voltadas para os diversos modernismos existentes no Brasil, seja dos diferentes campos do conhecimento (ciências sociais e humanas, artes visuais, arquitetura, literatura, teatro e música etc.), seja das diferentes perspectivas e subjetividades historicamente invisibilizadas (de mulheres, pessoas negras, LGBTQIAPN+, quilombolas, sujeitos do campo, indígenas ou outras que reivindiquem sua voz).”
Early Morning Activity: New records of diurnal behavior in Mexican bats
Authors: Aguilar Rodríguez Pedro Adrián , Castellanos Osorio Iván Arturo , Aguilar-López Melany , Pérez Sánchez Cristopher Manuel
Published: October 2024

Bats are predominantly nocturnal animals, but some studies, mainly from temperate regions and islands, report bats flying during the day. We report the diurnal foraging of three species of bats in Mexico, one species of the family Vespertilionidae, and two Phyllostomidae (Anoura and Artibeus). In addition, we document the first in situ record of fruit consumption on the ground for Artibeus. Diurnal flight in bats is a poorly documented behavior in the tropics. Furthermore, we suggest that extreme heat and drought may influence this behavior, as two reports occurred during periods of drought.

This study examined how changes in macroeconomic variables impact financial performance of Nigerian banks from 2010 till 2021 using panel data and estimated utilising panel regression analysis and descriptive analysis. The multiple regression model used Real GDP Growth (RGDPG), lagged Real GDP Growth (RGDPG (-1), Inflation (INF), Exchange Rate (EXR), Interest Rate (PLR), Money Supply Growth (GMS), and Liquidity Ratio (LIQ) as proxies of macroeconomic variables and as independent variables while financial performance, captured by both asset and equity returns (ROA) and (ROE) were dependent variables. With the exception of INF plus RGDPG, the panel regression analysis results showed that changes in most of the macroeconomic variables have negative and significant impacts on the financial performance of Nigerian banks. RoA and RoE are negatively and negligibly impacted by real GDP, whereas both RoA and RoE are positively and negligibly impacted by inflation. The research recommended that when creating and putting into practice strategic plans, Nigerian banks should consider how macroeconomic conditions may affect their operations and financial performance. Furthermore, banks are encouraged to be involved in the development of any policies that may affect their operations.

A pesquisa foca na governança da gestão e fiscalização dos contratos administrativos no âmbito da Polícia Militar do Paraná, que por sua vez, quando realizadas de forma diligente e por meio de boas práticas, essas atividades garantem a execução contratual conforme os termos acordados. O estudo procurou abordar aspectos sobre as atividades do gestor e fiscal, delineando a despeito dos perfis/características, casos de impedimento para exercício das funções e as práticas de governança na gestão e fiscalização em contratos da administração pública. Entendemos que por meio das práticas de boa governança se estabelece a proteção aos atos de gestão e fiscalização nas contratações, assim sendo, explorou-se a importância da inclusão do tema Gestão e Fiscalização de Contratos nas grades curriculares dos cursos de formação, especialização e aperfeiçoamento, destacando em paralelo a capacitação contínua. O impacto positivo que um programa estruturado de capacitação pode frutificar na melhoria da eficiência, na mitigação de riscos e na redução de conflitos contratuais. As atividades de capacitação específicas promovem conhecimento profundo das obrigações contratuais e das melhores práticas de gestão e fiscalização. Considerando os objetos ou serviços contratados pela PMPR, o presente estudo trouxe a sugestão da criação de um Manual Técnico aos militares estaduais, visto a peculiaridade e a complexidade do objeto ou prestação de serviços, o que entendemos que promoverá a cultura de governança, integridade e excelência.
Evaluating Convolutional Neural Network Architecture for Historical Topographic Hardcopy Maps Analysis: A Study on Training and Validation Accuracy Variation

Published: October 2024

Convolutional Neural Networks (CNN) are widely used for image analysis tasks, including object detection, segmentation, and recognition. Given the advanced capability, this study evaluates the effectiveness and performance of CNN architecture for analysing Historical Topographic Hardcopy Maps (HTHM) by assessing variations in training and validation accuracy. The lack of research specifically dedicated to CNN’s application in analysing topographic hardcopy maps presents an opportunity to explore and address the unique challenges associated with this domain. While existing studies have predominantly focused on satellite imagery, this study aims to uncover valuable insights, patterns, and characteristics inherent to HTHM through customised CNN approaches. This study utilises a standard CNN architecture and tests the model’s performance with different epoch settings (20, 40, and 60) using varying dataset sizes (288, 636, 1144, and 1716 images). The results indicate that the optimal operation point for training and validation accuracy is achieved at epoch 40. Beyond epoch 40, the widening gap between training and validation accuracy suggests overfitting. Hence, adding more epochs does not significantly improve accuracy beyond the optimum phase. The experiment also shows that the CNN model obtains a training accuracy of 98%, validation accuracy of 67%, and F1-score overall performance of 77%. The analysis demonstrates that the CNN model performs reasonably well in classifying instances from the HTHM dataset. These findings contribute to a better understanding of the strengths and limitations of the model, providing valuable insights for future research and refinement of classification approaches in the context of topographic hardcopy map analysis.

Methane (CH₄), a potent greenhouse gas, significantly contributes to climate change and global warming. Its impact over 100 years surpasses carbon dioxide (CO₂) by 28 times. Addressing methane emissions, particularly from oil and gas production activities such as transmission pipelines, is imperative. One promising avenue is the development of reliable sensors to detect and mitigate methane leaks and prevent hazardous issues. Optical-based methods present notable advantages, including versatility and remote operation, making them pivotal in this endeavor. This review article provides a concise overview of optical-based methane identification technologies, encompassing sensing materials, absorption spectra, operational mechanisms, and recent advancements. Potential perspectives are explored, and inferences from this assessment are also derived. Emphasizing the significance of optical fiber-based methane detection methods, the authors advocate for further research to support ongoing efforts and foster innovation in this critical area.
