Recent studies show that Generative Adversarial Networks (GANs) can improve intrusion detection performance by generating synthetic attack traffic, balancing imbalanced datasets, enhancing adversarial robustness, and serving as anomaly detectors. This survey provides a comprehensive and systematic review of GAN-based intrusion detection system (IDS) research, analyzing the architectures employed—including Wasserstein GANs, conditional GANs, self-attention GANs, and specialized multi-generator designs—together with their applications, datasets, and evaluation metrics. Unlike previous surveys, we extend the scope to resource-constrained Internet of Things (IoT) and federated scenarios, where lightweight and tabular GANs can process sensor data and operate on edge devices. We also examine deployments in software-defined networking environments. We propose a unified evaluation framework that reports class-wise precision, recall and macro-F1-scores, per-attack metrics, computational cost, and statistical similarity tests, and we emphasize the need for interpretable and multi-modal approaches that fuse network flows with logs or threat intelligence. Emerging paradigms including GANs combined with large language models, quantum GANs, diffusion models, and reinforcement learning are surveyed, and open challenges such as training instability, mode collapse, hyper-parameter tuning, and ethical dual-use concerns are discussed. By synthesizing recent advances and outlining future research directions, this survey provides a comprehensive and forward-looking reference for practitioners and researchers developing robust, privacy-preserving, and adaptive GAN-based intrusion detection systems.</p></div>","PeriodicalId":54354,"journal":{"name":"Arabian Journal for Science and Engineering","volume":"51 -","pages":"179 - 203"},"PeriodicalIF":2.9,"publicationDate":"2026-02-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12920325/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147272963","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Accurate identification of breathing patterns facilitates the assessment of respiratory function and supports early detection of anomalies, including COPD, pneumonia, asthma, and COVID-19. In this paper, we promote a two-step process that first estimates breathing sound signal envelope (in time domain) and then analyzes the envelope peaks/valleys to calculate the respiratory cycle.

We examine the practicality, scalability, and efficacy of these methods in both healthy and pathological cases, highlighting their potential for integration into real-world respiratory monitoring and screening systems.

We analyzed EEG data from 61 children with ADHD and 60 healthy controls (aged 7–12 years) during a visual attention task. EEG signals were recorded from 19 channels at a sampling rate of 128 Hz. Prior to applying machine learning algorithms, the data were pre–processed using a 50 Hz notch filter, a band–pass filter with cut–off frequencies of 4–40 Hz, and independent component analysis (ICA). Feature extraction focused on spectral power across four frequency bands (theta, alpha, beta, and gamma), as well as the frontal–parietal theta–alpha ratio, mean, standard deviation (SD), entropy, and root mean square (RMS). RNN, GRU, and LSTM models were then evaluated and compared. The results showed that the LSTM model outperformed the other architectures, achieving an accuracy of 64.53% in distinguishing individuals with ADHD from controls.

The region includes at least 3000 individual, small-volume, predominantly mafic volcanoes. A review indicates that volcanology research has increased in the number of peer-reviewed, international publications since the early 2010s, coinciding with the Volcanic Risk of Saudi Arabia (VORiSA) programme (~ 2012–2015)—a collaboration involving King Abdulaziz University in Jeddah, as well as Auckland University and Massey University in New Zealand. This research mainly focused on the Rahat Volcanic Field, one of the largest and longest-lived in the region, situated between the major Saudi cities of Jeddah, Makkah, and Al Madinah. The last recorded eruption, which took place in 1256 CE near Al Madinah, led to geological mapping under the joint programmes of the United States and Saudi Geological Surveys (USGS–SGS) (~ 2015–2018). These efforts, primarily for volcanic hazard assessment, have resulted in the most comprehensive volcanological summary of any Saudi Arabian volcanic field, partly due to the outcomes of the VORiSA programme. Despite these advances, due to the extensive territorial coverage, diversity of volcanism, and the large number of volcanoes, alongside a limited focus on volcano-scale geological research, several critical knowledge gaps remain. These include a lack of spatio-temporal understanding of volcanic events within individual fields, detailed studies on specific volcanoes at the event scale using advanced analytical techniques, investigations into the impacts of dispersed volcanic ash, and insufficient evidence-based scenario modelling for potential future eruptions. It is also noted that future work should focus on integrating high-resolution geological mapping, developing eruption scenarios, and conducting hazard simulations.</p></div>","PeriodicalId":54354,"journal":{"name":"Arabian Journal for Science and Engineering","volume":"51 -","pages":"223 - 253"},"PeriodicalIF":2.9,"publicationDate":"2025-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147342811","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}
