The parameters studied were the opening diameter (140 and 240 mm), number and location of the openings and the shear span-to-depth ratio (<i>a/d</i>). These beams were divided into Group I (<i>a/d</i> = 0.9) and Group II (<i>a/d</i> = 0.5). In each group, one beam had no opening to serve as the control beam. Two beams had one opening in the shear area, two had one at the mid-span of the beam and two had two openings, one on each side of the beam. Finite element modeling with strong correlation with the laboratory results was performed. The results showed that an increase in <i>a/d</i> caused a decrease in the final strength of the beam. The number of openings and their locations on the load transfer path were factors that significantly reduced the ultimate load borne by the beam. Comparison of the test results with the relations provided in design regulations indicated that the ultimate strengths of the beams were higher than the values obtained from the regulations.

As a result, a seismic-induced damage detection method utilizing deep learning has been developed to overcome the limitations of conventional techniques. Structure health monitoring (SHM) has emerged to address the limitations of the traditional methods of visual inspections, and among the most effective automatic feature extractor methods is Deep Learning Neural Networks (DLNNs). The DLNN method has proven highly effective compared to other methods, such as traditional methods used in damage detection when used as a feature extractor for seismic-induced damage detection. This study proposes a novel deep learning-based damage detection method for automatically extracting damage features from time series data, eliminating the need for intermediate preprocessing tools. The CNNs algorithm attains a validation accuracy of 91% when applied to a 7-story frame structure by subjecting the structures to different sets of incremental dynamic loading. The study investigates real-time applications, including environmental variables such as noise and temperature effects, examining unseen datasets of different earthquake groups and validating multiple structures in synthesis datasets. The algorithm is further investigated using the IASC-ASCE Benchmark experimental dataset conducted at the University of British Columbia laboratory. A comparative analysis is also performed in terms of time and performance on different deep learning algorithms, such as LSTM, 1D CNN, 2D CNNs and DNNs, while the 1D-CNNs showed the best performance. The results reveal that the proposed method effectively quantifies damage in different structures, including 7-story story steel and concrete structures, and the IASC-ASCE Benchmark dataset, with 93% validation accuracy.

The centralization of blood supply facilities for economic reasons and an increase in traffic volume have led to significant delays in the use of traditional emergency vehicles. The aim of the proposed mathematical model is to minimize logistics costs by strategically positioning launch and refueling stations and assigning requests to these stations. The proposed approach employs integer binary linear programming to offer four possible scenarios that consider the flight range and supply node capacity of the drone. The study conducted a scenario-based analysis to examine the primary decision-making process for transporting blood groups and identified the optimal configuration for launching and refueling stations based on 50 group requests. The study uncovered two essential factors, NL and NR, which signify the ideal number of launching stations and the number of refueling stations situated away from the optimal launching sites. The findings offer decision-makers the precise number of stations necessary for an ideal outcome, whereas information on refueling station locations assists in resource distribution planning. Introducing refueling stations for blood supply can extend the mission range and improve coverage in nonemergency situations. Gradual implementation can prevent operational disruptions, such as station closures. This approach can also reduce delivery times and minimize delays, potentially saving lives, as refueling stations have a significant impact on the management of blood supply and logistics.</p>","PeriodicalId":8109,"journal":{"name":"Arabian Journal for Science and Engineering","volume":"2 1","pages":""},"PeriodicalIF":2.9,"publicationDate":"2024-09-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142256156","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Following preprocessing, which includes converting text to lowercase, removing punctuation, extra whitespace, numbers, and non-ASCII characters, a thorough analysis reveals high-frequency words. The research extensively compares three-word embedding techniques—CountVectorizer, GloVe, and bidirectional encoder representations from transformers (BERT)—in combination with two machine learning models (support vector classifier and logistic regression) and four deep learning models [artificial neural network (ANN), recurrent neural network (RNN), bidirectional gated recurrent unit (Bi-GRU), bidirectional long-short term memory (Bi-LSTM)] for hate speech detection.

Accurately locating mobile sensor nodes remains a challenging task. The precisely identifying event source location is very important. To locate mobile sensor nodes there is a need of developing an efficient localization method. Most of the researcher have used multiple anchor nodes for localization. Therefore, in resource constraint networks reducing number of anchor nodes is an open research issue. The main idea of this work is to propose a localization method using single anchor node. To achieve this, a novel coordinated auto-localization algorithm with particle swarm optimization (PSO) is introduced to enhance localization and tracking of mobile sensor nodes. A mathematical framework has been developed which uses parallel coordinate system to identify location and PSO to track movement pattern of sensor nodes. PSO minimized localization error by refining position accuracy through iterative convergence. It achieves 10% reduction in localization error and a 25% increase in correctly localized nodes, with an overall tracking precision of 80%. Comparative analysis with different techniques like mobile anchor positioning with mobile anchor & neighbor, fish swarm optimization algorithm, DV-hop localization, and autonomous groups particle swarm optimization shows that this method reduces the average localization error to 10% and improves localization efficiency by reducing the required time by 16% compared to other techniques.

All the tested shapes have three inclusion angles (<i>θ</i> = 30, 45, and 60°), and three heights (0.1, 0.15, 0.2 m).
