Research ArticleOpen accessIn the keywordsPersian Curve Versus Monte Carlo MethodAbdolrasoul Ranjbaran, Mohammad Ranjbaran, Fatema RanjbaranThe Monte Carlo Simulation method is a powerfultool for solving problems including random variables. The basic idea toimplement a Monte Carlo simulation is to first generate samples of randominputs from their assumed distributionfunctions and then perform a deterministic calculation on the generated randominputs, based on mathematical modeling of the system, to obtain output results.An early version of Monte Carlo simulation … …International Journal of Structural Glass and Advanced Materials Research, Vol. 5, Issue 1 · 6 Jul 2021 · 8,304 accessesView PDFCite
Research ArticleOpen accessIn the keywordsA Modification of the Ridge Type Regression EstimatorsMoawad El-Fallah Abd El-SalamProblem statement: Many regression estimators have been used to remedy multicollinearity problem. The ridge estimator has been the most popular one. However, the obtained estimate is biased. Approach: In this stuyd, we introduce an alternative shrinkage estimator, called modified unbiased ridge (MUR) estimator for coping with multicollinearity problem. This estimator is obtained from Unbiased Ridge Regression (URR) in the same … …American Journal of Applied Sciences, Vol. 8, Issue 1 · 31 Jan 2011 · 7,641 accessesView PDFCite
Research ArticleOpen accessIn the keywordsPrediction in Complex Dimension Using Kolmogorov's Set of AxiomsAbdo Abou Jaoude, Khaled El-Tawil, Seifedine KadryProblem statement: The five basic axioms of Kolmogorov define the probability in the real set of numbers and do not take into consideration the imaginary part which takes place in the complex set of numbers, a problem that we are facing in many engineering systems. Approach: Evaluate the complex probabilities by considering supplementary new imaginary dimensions to the event occurring … …Journal of Mathematics and Statistics, Vol. 6, Issue 2 · 30 Jun 2010 · 8,523 accessesView PDFCite
Research ArticleOpen accessIn the keywordsIntrahydrogen Bonding and Transition States Between Enol and Enethiol Tautomers in β-ThioxoketonesBahjat A. Saeed, Rita S. Elias, Ebraheem Abdu MusadProblem statement: Hydrogen bonding is one of the most important concepts in chemistry because it is crucial to understand many different interactions both in gas phase and in condensed media. A particular subset is presented by the intramolecular hydrogen bonds where two ends of the same molecule interact, resulting in a ringlike structure. Approach: The study involved theoretical investigation of … …American Journal of Applied Sciences, Vol. 8, Issue 8 · 18 Jul 2011 · 7,457 accessesView PDFCite
Research ArticleOpen accessIn the abstractMonitoring of the Saiga Population: Balancing Nature and AgricultureZhanbolat Ibraibekov, Saule Atshabarova, Ermek Gabdullin et al.The rapid recovery of the Saiga population (Saiga tatarica) in Kazakhstan represents a significant conservation success; however, it has simultaneously generated complex ecological and socio-economic challenges in steppe ecosystems. This study evaluates the relationships between Saiga population density and pasture ecosystem condition and identifies ecological thresholds relevant to balancing biodiversity conservation and sustainable agricultural land use. The research is based … …OnLine Journal of Biological Sciences, Vol. 26, Issue 4 · 27 Oct 2026 · 50 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffects of Vitamin E on Stress Resorption, Lipid Profile and Reproductive Performance of Sokoto Red GoatsKehinde Matthias OKUKPE, Ling Shing Wong, Geetha Subramaniam et al.Vitamin E (α-tocopherol) plays a critical role in animal nutrition as an antioxidant, contributing to anti-inflammatory responses, immune function, and gene expression regulation. This study aimed to determine the optimal dietary level of vitamin E to alleviate the effects of environmental stress in Sokoto Red Goats transported from their native dry savannah belt to the humid derived savanna belt of … …OnLine Journal of Biological Sciences, Vol. 26, Issue 1 · 20 Mar 2026 · 1,513 accessesView PDFCite
Research ArticleOpen accessIn the abstractEvaluating the Hepatoprotective and Anti-Inflammatory Efficacy of Herbal Extracts for NAFLD PreventionHessah Mohammed Al-Muzafar, Kamal Adel AminNatural products may offer a safer approach for mitigating the increasing prevalence of Non-Alcoholic Fatty Liver Disease (NAFLD). This study aimed to evaluate the hepatoprotective and anti-inflammatory effects of a water-based extract of Moringa Oleifera leaf, Milk Thistle, and Cassia (MO-MT-CA) against High-Fat, High-Sugar Diet (HFSD)-induced fatty liver. The research focuses on assessing lipid profiles and inflammation as key markers … …OnLine Journal of Biological Sciences, Vol. 25, Issue 3 · 23 Nov 2025 · 1,971 accessesView PDFCite
Research ArticleOpen accessIn the abstractPersonalized Recommendation System: Web of Things Using Modular Density-Based Community DiscoveryVinod Patidar, Jayashree A. Patil, Sonika Thapak et al.Community discovery is the cornerstone and core of study in customized recommendation, assembling group features and social network analysis on the web of things. Conventional community discovery methods, however, struggle with difficulties including low accuracy, delayed convergence, modularity resolution limits and more when dealing with more complicated social networks. Because of this, differential evolution and module density are included in … …Journal of Computer Science, Vol. 20, Issue 9 · 21 Jun 2024 · 5,644 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Suggested Nonparametric Bivariate Logistic Density Estimator with Application on the Productivity of Egyptian Wheat during 2019/2020Samah M. Abo-El-HadidIn this study, the nonparametric standard logistic density estimator, introduced by Abo-El-Hadid (2018), is extended to the bivariate case. The multiplicative standard logistic distribution is used as a kernel function to derive the bivariate kernel estimator. The statistical properties of the resulting estimator are studied, which are: The asymptotic bias, variance, Mean Squared Error (MSE) and Integrated Mean Squared Error … …Journal of Mathematics and Statistics, Vol. 17, Issue 1 · 27 May 2021 · 6,716 accessesView PDFCite
Research ArticleOpen accessIn the abstractImpact of Vitamin D Deficiency on Cardio Metabolic Ageing in Middle Aged Adults in India: A Comparative AnalysisSumit Kumar, Adithi K, Shailaja S MoodithayaAdvancing age is accompanied by a gradual deterioration in physiological function, resulting in an increased risk of chronic diseases and early mortality. Growing evidence suggests that inadequate vitamin D status may be associated with unfavourable metabolic and cardiovascular alterations. Nevertheless, information regarding the association of vitamin D status with integrated cardio-metabolic biomarkers of ageing in middle-aged adults is currently limited. … …OnLine Journal of Biological Sciences, Vol. 26, Issue 3 · 3 Sep 2026 · 738 accessesView PDFCite
