This study addresses this issue by proposing a new protective algorithm for the fast and accurate detection of HIAFs and their differentiation from other TEs. The proposed method uses the third harmonic angle of the residual current (THARC) as a key identification feature, which is extracted using a fast, accurate two-layer Master-Slave ADALINE (MS-ADALINE) architecture. The THARC is then smoothed using the Moving Average (MWA) technique, and a new index is introduced for fault detection. Simulations conducted in the EMTP-RV software environment demonstrate that the proposed algorithm can distinguish HIAFs from other TEs under noisy and complex conditions with an accuracy of 99.17% and a detection time of 20 msec.

Different from the existing OMA, like Time Division Multiple Access (TDMA), the NOMA utilizes the power sector to serve distinct users continuously. The previous works on NOMA have highly concentrated on the spectral efficiency improvement. Meanwhile, this experiment concentrates on improving the Secrecy Sum Rate (SSR) in MIMO-NOMA systems by addressing the underlying nonlinear characteristics of both power allocation and signal detection tasks. In the MIMO-NOMA system, the Singular Value Decomposition (SVD) technique is employed to break down the channels in the network. The complex and nonlinear nature of the communication environment, most importantly under secrecy constraints and the multi-user interference, demands a hybrid optimization and a learning-aided solution. To this end, the designed framework leverages the Fitness-based Random Number Swarm Bipolar Algorithm (FitRand SBA) to fine tune the power allocation for near and far users, maximizing the SSR in a nonlinear multi-dimensional search space. Simultaneously, a deep learning-assisted signal detection mechanism utilizing an Adaptive Residual Bi-directional Recurrent Neural Network (AR-BiRNN) is designed to handle the nonlinear temporal dependencies and inter-reference in the signal decoding. The FitRand SBA is employed to optimize the AR-BiRNN parameters, adapting to the wireless channel’s nonlinear behavior. The nonlinear modeling, optimization, and detection methods collectively improve the communication functionality of the MIMO-NOMA system. The simulation results on a 2x2 MIMO-NOMA setup demonstrate that the suggested model attains 28.94 % SSR improvement over conventional optimization algorithms and achieves 95.16 % accuracy contrasted to the existing models.

However, there are still some deficiencies when assessing the seismic performance of continuous reinforced concrete bridge structures: 1) Insufficient consideration of the randomness of structural materials and geometric dimensions in stochastic finite element analysis; 2) Subjectivity in selecting and constructing seismic intensity measures (IM) during component fragility analysis, with significant variability in the functional relationship between IM and Engineering Demand Parameters (EDP); 3) Lack of a database for repair measures and decision criteria (such as repair time and repair cost) for bridge component categories and damage states based on national specifications. The study aims to investigate the seismic performance of a continuous beam bridge by considering the randomness of material and component parameters, as well as the randomness of seismic ground motion, through stochastic finite element analysis. Machine learning and symbolic regression algorithms will be employed to perform component-level fragility analysis for different bridge elements. Targeting a continuous girder bridge, this study conducts stochastic finite element analysis incorporating material/component parameter variability and ground motion randomness. Machine learning algorithms (Ridge Regression, K-means/CLA clustering, Pearson/Spearman/Kendall correlation coefficients, Distance/Maximal Information Coefficients) combined with symbolic regression via Genetic Programming (GP) are employed for component-level fragility analysis. A repair strategy database incorporating cost and time metrics is subsequently established to assess bridge seismic performance using decision indicators (repair/reconstruction costs, downtime). The results indicate that bridge repair costs and time exhibit pronounced nonlinear growth with increasing PGA. At low intensities (PGA &lt; 0.5 g), longitudinal-direction costs slightly exceed transverse-direction values (four components, e.g., piers, contributing 90 % of total costs), while transverse-direction repair complexity surges at high intensities (PGA &gt; 0.5 g) due to shear key failures. The coefficient of variation (COV) peaks at moderate-high intensities (0.5–0.8 g) and declines thereafter as structural collapse modes converge. Critical cost-effectiveness equilibrium thresholds are identified at 0.92 g (transverse) and 0.93 g (longitudinal), beyond which repair costs (&gt;1.5171 million yuan) surpass reconstruction expenses, serving as pivotal criteria for post-earthquake decision-making.</div></div>","PeriodicalId":48648,"journal":{"name":"Ain Shams Engineering Journal","volume":"16 12","pages":"Article 103653"},"PeriodicalIF":5.9,"publicationDate":"2025-09-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145049800","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
