Research ArticleOpen accessEvery word in the titleAnalysis of the Over-Voltages Produced by Lightning Strokes in the Power Transmission System in the Southern Region of Saudi ArabiaA. U. Al-Abdulaziz, S. M. Bashi, A. A. AlthubaitiThis study deals with the simulation of lightning strokes and their effects on power network in the southern region of Saudi Arabia. The network consists of main generating stations, substations and the power transmission lines. The transient performance of the system has been investigated using the EMTP (Electro Magnetic Transient Program). Some surges were introduced to the network as in … …American Journal of Applied Sciences, Vol. 3, Issue 3 · 31 Mar 2006 · 7,213 accessesView PDFCite
Research ArticleOpen accessIn the keywordsOptical Character Recognition System for Arabic Text Using Cursive Multi-Directional ApproachMansoor Al-A'ali, Jamil AhmadThis paper presents a novel new technique based on feature extraction and on dynamic cursor sizing for the recognition of Arabic Text. The most challenging area in Arabic OCR (AOCR) research is the segmentation of words into their sub-words and their individual characters. Several rules are defined that govern the size and movement of the cursor through each segment. The … …Journal of Computer Science, Vol. 3, Issue 7 · 31 Jul 2007 · 6,970 accessesView PDFCite
Research ArticleOpen accessIn the abstractAssessing the Comparative Effectiveness of Ensemble CatBoost Versus XGBoost Models in Predicting Heart Disease OutcomesManivannan D., G. Gifta Jerith, G. Chandra Sekhar et al.Cardiovascular Diseases (CVDs) are a common form of heart disease that remains a significant global cause of mortality, responsible for more than 30% of all fatalities. Without intervention, the global fatality count is projected to reach 22 million by 2030. Arterial plaque buildup may impede blood flow, potentially causing heart attacks or strokes. A combination of risk causes, including lack … …Journal of Computer Science, Vol. 22, Issue 4 · 4 May 2026 · 1,544 accessesView PDFCite
Research ArticleOpen accessIn the abstractStroke Risk Assessment with Classical ML MethodsMohammad Aref Alshraideh, Najwan Alshraideh, Abedalrahman Alshraideh et al.Stroke, often caused by a disruption in the supply of essential oxygen, blood, and nutrients to the brain, represents a significant global health challenge. Due to limited resources, developing countries like Ethiopia face unique obstacles in identifying and treating strokes. This study explores the potential of Machine Learning (ML) techniques to predict stroke risk and facilitate early detection and intervention. … …Journal of Computer Science, Vol. 21, Issue 1 · 18 Dec 2024 · 4,649 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Effects of Oil Film Shape on Piston Ring and Liner Tribology Under Mixed LubricationAbbas Razavykia, Cristiana Delprete, Eugenio Brusa, Yaser HosseiniMechanical power loss reduction at lubricated reciprocating and rotating components is recognized as an approach to improve the efficiency and to reduce the emissions of Internal Combustion Engines (ICEs). To achieve these goals, the instantaneous investigation of lubrication characteristics is required. Piston ring pack is of paramount importance as it is known as major contributor to frictional losses and energy … …American Journal of Engineering and Applied Sciences, Vol. 14, Issue 4 · 10 Nov 2021 · 6,523 accessesView PDFCite
Research ArticleOpen accessIn the abstractStroke Associated with Infective Endocarditis. Frequency and Prognostic ImplicationsJuan José Mengual Chirife, Manuel Gómez-Choco, Ester MoralStroke can be one of the most severe complications of Infective Endocarditis (IE) and it happens in 14% of patients with IE. Therefore, we aimed to review stroke frequency in patients diagnosed with IE in our hospital from 2010 to 2020. We defined it as IE-Associated Stroke (IEAS) when the stroke happened one month before or after IE's diagnosis. Sixty-six … …American Journal of Infectious Diseases, Vol. 17, Issue 4 · 7 Sep 2021 · 6,860 accessesView PDFCite
Research ArticleOpen accessIn the abstractApplying Neural Network-Based Approach to Sickle Cell Disease-Related Pain ClassificationZacchaeus Omogbadegun, Israel Ogundele, Olufunke OladipupoSickle Cell Disease (SCD), an inherited Red Blood Cell (RBC) disorder, is characterized by anaemia, end-organ damage, unpredictable episodes of pain and early mortality. SCD affects 25% of people living in Central and West Africa causing life threatening “silent” strokes and lifelong damage. Nigeria accounts for 50% of SCD births worldwide (estimated 150,000 of 300,000 babies born with Symptomatic Sickle … …Journal of Computer Science, Vol. 15, Issue 6 · 28 Jun 2019 · 7,678 accessesView PDFCite
