Research ArticleOpen accessEvery word in the titleGeomagnetic Anomalies: LineamentsGiovanni Pietro Gregori, Bruce Allen Leybourne, Ugo Coppa, Giuseppe LuongoGeomagnetic anomaly maps can be interpreted according to either (i) To the electromagnetic (e.m.) Induction by the solar wind that generates telluric currents aimed to oppose the geomagnetic field originated by the deep geomagnetic dynamo, or (ii) By stray currents that outflow from the deep Earth’s circuitry. The results correlate with other morphological, geodynamic, and tectonic features, which represent a … …American Journal of Engineering and Applied Sciences, Vol. 18, Issue 1 · 2 Jan 2025 · 4,815 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleDetecting Anomalies in IoT Using Intuitionistic Fuzzy Clustering AlgorithmsVijo Arul Selvi M., Fehmin Nadira Laskar, Fokrul Alom Mazarbhuiya et al.Intuitionistic Fuzzy Sets (IFS) are convenient ways to represent the vagueness and uncertainty inherent in any dataset. There are many uses of these. One such use is the Fuzzy C-Means (FCM) algorithm, which clusters the data objects into a pre-assigned (c) number of fuzzy clusters, which has been adopted in many fields, namely, pattern classification, anomaly detection, fraud identification, etc. … …Journal of Computer Science, Vol. 22, Issue 2 · 2 Mar 2026 · 1,600 accessesView PDFCite
Review ArticleOpen accessEvery word in the titleA Succinct Review on Identification of Network Anomalies and Protection in Cyber-Physical SystemsShalini Kumari, Chander Prabha, Prakash Srivastava et al.Advanced cyberattacks outperform traditional threat detection methods in the rapidly expanding cybersecurity field. Advanced Machine Learning (ML) algorithms can detect network traffic and system problems using AI-based Anomaly Detection (AD) for cybersecurity in real-time. Signature-based systems may overlook new and subtle threats. This paper examines Artificial Intelligence (AI) driven AD systems' design, methodology, and efficacy. The process includes data preprocessing … …Journal of Computer Science, Vol. 21, Issue 6 · 29 May 2025 · 5,234 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleCost-Efficient Deadline Constrained Scientific Workflow Scheduling in Infrastructure-as-a-Service Clouds by Disqualifying Tasks with AnomaliesAnver Shahabdeen Rahumath, Santhosh Rajendran, Natarajan Mohanasundaram, Abdul Rahiman MalangaiCloud computing has transformed the way businesses and consumers think about their data and businesses. As a result, cloud computing is described as the on-demand availability of all computer system resources via the Internet as a paid service. Enhancing security is a major problem in cloud computing, which is also a major research topic because data is stored and processed … …Journal of Computer Science, Vol. 18, Issue 6 · 27 Jun 2022 · 5,793 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleUsing Robust Statistics, Exploring Document Analysis and Gis for Defining and Localizing Geochemical Anomalies-Case Study in Sin Quyen Copper Mine, Lao Cai Province, Viet NamQuoc Lap Kieu, Huu Tap VanApplication of robust statistic and Exploratory Data Analysis (EDA) as well as the support of Geography Information System (GIS) for defining and assessing geochemical anomalies. The research was conducted in Sin Quyen copper mine, Lao Cai province, Viet Nam with 1,284 combination of aquatic sedimentary geochemical sample in scale of 1/200,000. The area of 5,717.8 km2 was chosen to make … …Current Research in Geoscience, Vol. 7, Issue 2 · 1 Aug 2017 · 8,404 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleAnomalies in a Fetus Exposed to Methotrexate in the First TrimesterLandon B. Lorenz, Eric J. KnudtsonThe increasing use of methotrexate for multiple indications in reproductive age women will likely lead to more frequent incidence of fetal exposure. Methotrexate is sometimes used for medical termination of first trimester pregnancy in combination with misoprostol. Teratogenesis in women exposed to low-dose methotrexate used for treatment of rheumatic conditions has been reported, but it has also been suggested that … …American Journal of Pharmacology and Toxicology, Vol. 2, Issue 4 · 31 Dec 2007 · 7,653 accessesView PDFCite
Research ArticleOpen accessIn the keywordsIoT Anomaly Detection Using Picture Fuzzy Clustering ApproachFehmin Nadira Laskar, Vijo Arul Selvi M., Fokrul Alom Mazarbhuiya et al.Improving the effectiveness of security systems without slowing them down is a major challenge in cybersecurity. Many methods have been explored for detecting anomalous behaviour in network data, with fuzzy set-based approaches standing out for their potential. The Internet of Things (IoT) consists of many connected devices that constantly generate large amounts of data and perform tasks in real time. … …Journal of Computer Science, Vol. 22, Issue 3 · 6 Mar 2026 · 1,515 accessesView PDFCite
Research ArticleOpen accessIn the keywordsContinuous Wavelet Transform Based Spectral Decomposition of 3d Seismic Data for Reservoir Characterization in Oyi Field, se Niger DeltaChukwuemeka Ngozi Ehirim, Andifon Sylvester AkpanContinuous Wavelet Transform (CWT) is one of the most used wavelet transform based spectral decomposition methods in the direct detection of hydrocarbons and as an indicator of stratigraphic variability due to its optimal time-frequency resolution and variable time window requirements. CWT based spectral decomposition was applied on a 3D Post Stack Time Migrated (PSTM) seismic data acquired over a producing … …American Journal of Applied Sciences, Vol. 14, Issue 8 · 28 Apr 2017 · 7,791 accessesView PDFCite
Research ArticleOpen accessIn the keywordsCombating Cyber Terrorism-Assessment of Log for Malicious SignaturesKamalanaban Ethala, R. SeshadriEnhancing security to the networks and preventing the cyber attacks is a major issue in all domains. In this study, a new class of cyber terrorism is addressed where mischievous and malicious behaviour is the root cause for the modification of network data stored in an open database. An attempt is made in this study to develop an algorithm that … …American Journal of Applied Sciences, Vol. 10, Issue 12 · 7 Nov 2013 · 6,635 accessesView PDFCite
Research ArticleOpen accessIn the keywordsMicrotia After Ovulation Induction with LetrozoleM.D. Mohammed Al-SunaidiProblem statement: Letrozole gained lots of interest over the past decayed as a medication for ovulation induction to achieve monofollicular results, although few retrospective analysis of congenital anolamalies detected for babies who were conceived via this medication; the dispute still exist and the need for large multicenter studies are needed to resolve this issue. Approach: In the current report; we … …American Journal of Pharmacology and Toxicology, Vol. 6, Issue 4 · 17 Jan 2012 · 7,755 accessesView PDFCite
