Research ArticleOpen accessIn the abstractThe Lateral Reaction of a Deformable Inclined Surface on a Wheel with an Elastic TrunkSayel M. Fayyad, Suleiman Abu-Ein, Waleed MomaniProblem statement: This study is concerned with a very important problem belonging in the effects of deformable inclined surfaces on a wheel with an elastic trunk. These effects can be represented by two effects: A lateral withdrawal of the trunk and lateral shift of the ground. Also this study aims to study these effects and analyze them mathematically to find … …American Journal of Applied Sciences, Vol. 6, Issue 5 · 31 May 2009 · 7,028 accessesView PDFCite
Research ArticleOpen accessIn the abstractElectronic Energies in Delta Doped AlGaAs/GaAs HeterostucturesA. Meftah, H. Ajlani, A. Marzouki et al.The band bending of the potential at the AlGaAs/GaAs interface increases with the electrons concentration in the GaAs channel. This band bending is often ignored in the theoretical calculation of the electronic energies and a linear potential approximation was used. This led to imprecise energy values and occupied subband configurations. We have taken account of the band bending in the … …American Journal of Applied Sciences, Vol. 5, Issue 4 · 30 Apr 2008 · 6,931 accessesView PDFCite
Research ArticleOpen accessIn the abstractFramework of Regression-Based Graph Matrix Analysis Approach in Multi-Relational Social Network ProblemFord Lumban Gaol, Belawati WidjajaCommunity mining is one of the major directions in social network analysis. Social network analysis has attracted much attention in recent years. Most of the existing methods on community mining assume that there is only one kind of relation in the network and moreover, the mining results are independent of the users’ needs or preferences. However, in reality, there exist … …Journal of Mathematics and Statistics, Vol. 4, Issue 1 · 31 Mar 2008 · 6,922 accessesView PDFCite
Research ArticleOpen accessIn the abstractInverse Correlations for Multiple Time Series and Gaussian Random Fields and Measures of Their Linear DeterminismR.J. Bhansali, L. IppolitiFor a discrete-time vector linear stationary process, {X(t)}, admitting forward and backward autoregressive representations, the variance matrix of an optimal linear interpolator of X(t), based on a knowledge of {X(t-j), j≠0}, is known to be given by Ri(0)-1 where Ri(0) denotes the inverse variance of the process. Let A=Is-1Ri(0)ˉ1R(0)ˉ1, where R(0) denotes the variance matrix of {X(t)} and Is an … …Journal of Mathematics and Statistics, Vol. 1, Issue 4 · 31 Dec 2005 · 6,424 accessesView PDFCite
Research ArticleOpen accessIn the abstractMathematical Model of the Relationship between BGP Convergence Delay and Network TopologiesYahia Hasan JazyahBGP is a distant vector inters Autonomous System (AS) routing protocol that comes up after EGP to eliminate the inefficiency of EGP with respect to flexibility and scalability and to give support of an actual routing protocol. BGP handles the scalability problem using Classless Inter-Domain Routing (CIDR) and solves the inefficiency of EGP by accumulating all the possible route information … …Journal of Computer Science, Vol. 14, Issue 1 · 1 Jan 2018 · 9,248 accessesView PDFCite
Research ArticleOpen accessIn the abstractDetection of Exogenous Heavy Metal Pesticide Residues in Traditional Chinese Medicine Based on Fluorescent Carbon Quantum DotsYanan He, Shuyin WangThe analysis method based on fluorescent probes has received increasing attention due to its high sensitivity, fast response, and real-time visualization characteristics. Therefore, the application of fluorescent probes for rapid detection of heavy metal pesticide residues in traditional Chinese medicine is of great significance. This study innovatively synthesized B/N co-doped carbon quantum dots using 3-aminophenylboronic acid as the raw material, … …American Journal of Biochemistry and Biotechnology, Vol. 22, Issue 1 · 10 Apr 2026 · 1,610 accessesView PDFCite
Research ArticleOpen accessIn the abstractIntelligent Intrusion Detection System Using RF, SVM, and DT: A Comparison-Based KDD Data SetWalaa Hassan Elashmawi, Alaa Sheta, Ahmad Al-QeremThe rapid growth of technology has brought about many advantages, but has also made networks more susceptible to security threats. Intrusion Detection Systems (IDS) play a vital role in protecting computer networks against malicious activities. Given the dynamic and constantly evolving nature of cyber threats, these systems must continuously adapt to maintain their effectiveness. Machine Learning (ML) methods have gained … …Journal of Computer Science, Vol. 21, Issue 8 · 28 Aug 2025 · 5,818 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Role of Per Capita GDP in Intergenerational Mobility in Education: A Cross-Country StudyLida Fan, Meiying Zheng, Rong Luo, Alena AuchynnikavaThis study investigates the mechanism of how per capita GDP impacts intergenerational mobility in education. We propose an analytic framework in which per capita GDP affects educational mobility through government spending on education and other channels. Following this framework, this study conducts five-round estimations to examine the connections among per capita GDP, educational mobility, and government expenditure on education, using … …Journal of Social Sciences, Vol. 21, Issue 1 · 4 Feb 2025 · 8,194 accessesView PDFCite
Research ArticleOpen accessIn the abstractCooling Load Prediction in the Under-Actuated Zone with Multilayer Perceptron Artificial Neural NetworkYaddarabullah, Aedah Abd Rahman, Amna SaadThis study focuses on addressing the challenge of predicting cooling loads in under-actuated zones, where the variability in occupant behavior, environmental conditions, and electronic usage creates complex dynamics. Traditional models like Support Vector Regression (SVR) and E-Lastic-Net (ELN) often struggle to capture these non-linear relationships, leading to inefficient Heating, Ventilation, and Air Conditioning (HVAC) management and increased energy consumption. To … …Journal of Computer Science, Vol. 21, Issue 3 · 27 Jan 2025 · 5,300 accessesView PDFCite
