{"title":"Machine Learning Models for Predicting Flexural Behavior of FRP-Strengthened RC Beams","authors":"Nasih Habeeb Askander","doi":"10.24271/psr.2024.435650.1472","DOIUrl":"https://doi.org/10.24271/psr.2024.435650.1472","url":null,"abstract":"This study's objective is to overcome limitations in current design recommendations by exploring the application of machine learning to predict the flexural behavior of fiber-reinforced polymer (FRP)-strengthened reinforced concrete beams. Although FRP composites have completely changed structural strengthening, it might be challenging to predict bending moments with precision. This work fills the theoretical and experimental findings gaps by utilizing Artificial Neural Network (ANN) models in conjunction with computational techniques and statistical analysis. It includes gathering data, conducting a thorough literature review, and developing three models: Artificial neural network (ANN), Non-linear Regression (NLR), and Linear Regression (LR). Despite other models, the ANN model stands out for its superior performance and accurate predictions. Understanding material characteristics, FRP properties, and beam dimensions is critical in predicting flexural strength. The most significant parameter studied in this research is the overall depth of the beam (h), followed by the variation in bottom flexural reinforcement ( ρ s ). Additionally, the FRP ratio ( ρ f ) and beam width ( b ), which are both regarded as significant attributes, influence the flexural capacity of FRP-strengthened beams. The ultimate moment (M u ) may be predicted by the ANN model with an error range of -20% to +15%, indicating a significant advancement in strengthening approach optimization. This development could reduce the requirement for expensive experimental testing during construction, thereby enhancing the predictive capacity of structural engineering procedures. Furthermore, the design of flexurally strengthened RC beams with FRP may be made possible by depending on this model, specifically the ANN, without the need for experimental effort.","PeriodicalId":508608,"journal":{"name":"Passer Journal of Basic and Applied Sciences","volume":"89 11","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-06-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141389555","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There was a gap in knowledge regarding the prevalence and accurate species status of Bcc strains in the Kurdistan region of Iraq. Therefore, the current study aimed to direct molecular identification and characterization of Bcc species in respiratory tract infections of hospitalized patients in Duhok province based on PCR amplification and sequencing of the Bcc recA gene. The investigation also targeted the detection of the epidemic marker BCESM ( esmR gene) and the transmissibility marker cblA gene. Results revealed that seven Bcc isolates were identified out of 309 sputum and oropharyngeal swabs. The overall prevalence rate of Bcc was 2.26%, with a higher percentage of isolation in sputum specimens (8.51%, 4/47) compared with oropharyngeal samples (1.14%, 3/262). The results of direct antibiotic susceptibility testing revealed that Imipenem was the most effective antibiotic against Bcc isolates (100% sensitive); contrastingly, Cefixime showed no effect on the isolates. Based on the recA gene sequencing, six Bcc species have been identified, including B. cepacia , B. multivorans , B. cenocepacia , B. anthina , B. contaminans , and B. lata , whose sequence identities ranged from 99.71–100%. Each of B. anthina (OR662134), B. lata (OR662135), B. cenocepacia (OR662137), and B. contaminans (OR662140) were recorded as the first identified and reported Bcc species in Iraq. The transmissibility marker was found in three isolates of the identified Bcc complex species (42.85%, 3/7). Also, B. cepacia was found to be a transmissible epidemic strain ( cblA +/ esmR +). Identifying transmissible and epidemic strains of the Bcc complex in this region puts hospitalized patients at high risk of cross-infection, which may require active surveillance and further investigation.","PeriodicalId":508608,"journal":{"name":"Passer Journal of Basic and Applied Sciences","volume":"9 16","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141228755","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The interdisciplinary study explores how personality traits intertwine with language learning. Analyzing 495 EFL learners in Kurdistan universities, the research deploys statistical methods to uncover correlations between personality traits and language-learning strategies. The results unveil nuanced associations; for instance, Conscientiousness and Neuroticism influence memory strategies, while Conscientiousness and Agreeableness relate to cognitive strategies. Compensation strategies connect with Conscientiousness and Openness, and metacognition strategies demonstrate ties to Extroversion and Openness. Affective strategies align with Conscientiousness and Neuroticism, and social strategies are linked to Extroversion and Openness. These results emphasize the intricate dynamics of how personality traits influence language learning strategies, emphasizing the need for further investigation into the underlying mechanisms governing this interplay.","PeriodicalId":508608,"journal":{"name":"Passer Journal of Basic and Applied Sciences","volume":"110 8","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141234329","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A longitudinal study was conducted from May 2022 to February 2023 to analyze PAH concentrations in water samples collected across three seasons using a GC-MC6890 Agilent gas chromatograph. Samples were collected from Dukan Lake, the City's primary water source, to the last distribution stations within the city. The study focused on four prevalent PAHs: naphthalene, acenaphthylene, acenaphthene, and pyrene. Their concentrations were meticulously compared against established drinking water standards to assess potential health risks. Additionally, the influence of seasons on PAH levels and the impact of PAH concentration on the water's pH were investigated. The results revealed noteworthy seasonal variations in PAH concentrations, with higher levels observed during summer. Naphthalene concentrations were 20% higher in the summer compared to autumn/winter. Acenaphthylene and acenaphthene exhibited statistically significant differences in mean concentrations across the seasons (p-value < 0.0001), with naphthalene also showing significant differences between summer and autumn/winter. All PAH parameters exceeded standard limits in drinking water, posing potential risks to human health and aquatic organisms. Pyrene and other variables did not significantly affect pH (p-value = 0.9360). These findings emphasize the need for continuous monitoring and treatment strategies to mitigate PAH contamination and ensure the safety of the City's drinking water supply. This study provides valuable baseline data for future efforts and management of drinking water resources in Sulaimani City.","PeriodicalId":508608,"journal":{"name":"Passer Journal of Basic and Applied Sciences","volume":"37 8","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140425519","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The proposed approach makes use of the Pade approximation to enhance the performance of computation. The transformation to the Pade arrangement is particularly successful in quickly speeding up convergence and obtaining the solution when working with complex structures that demonstrate geometrically nonlinear properties. In contrast to previous approaches, the suggested method directly solves the problem by formulating an algebraic system of nonlinear equations using the Pade approximation. To arrive at an analytical solution, some of the most well-established methods that make use of iterative techniques include dynamic relaxation, finite element analysis, and minimum total potential energy. A comprehensive evaluation of the proposed technique's precision and reliability was conducted using six different numerical examples. The recommended method's accuracy, consistency, and computational efficiency are shown by carefully comparing the results with those of techniques that have been around for a long time. This work contributes to the advancement of numerical approaches for the analysis of complex structural behavior by providing a reliable and efficient alternative.
