Research ArticleOpen accessIn the keywordsOptimization of Penalty Parameter in Penalized Nonlinear Canonical Correlation Analysis by using Cross-ValidationIsamu NagaiThere is Canonical Correlation Analysis (CCA) as a way to find a linear relationship between a pair of random vectors. However, CCA cannot find a nonlinear relationship between them since the method maximizes the correlation between linear combinations of the vectors. In order to find the nonlinear relationship, we convert the vectors through some known conversion functions like a kernel … …Journal of Mathematics and Statistics, Vol. 11, Issue 3 · 22 Dec 2015 · 7,661 accessesView PDFCite
Research ArticleOpen accessIn the abstractBrain Tumor Segmentation and Classification Using HardNet Transformer With Gated Recurrent Unit ModelSaida D, Srinivas Adepu, Thade Lakshmi Devi et al.The uncontrolled growth of brain tumor cells presents a severe health risk, making early diagnosis and accurate classification essential for improving treatment outcomes. However, the existing approaches used for segmentation fail to delineate the tumor regions accurately due to a lack of global contextual information of brain tumors, resulting in poor classification performance. To overcome this limitation, this research proposes … …Journal of Computer Science, Vol. 22, Issue 9 · 26 Sep 2026 · 630 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Prediction Model for Information Anxiety of CSs Based on CMA-ES and XGBoostBin Wang, Li ShaoWith the rapid advancement of information technology, college students are increasingly facing the problem of information overload. Information anxiety, an emerging mental health issue, significantly impacts their studies, daily lives, and mental well-being. Given the limitations of existing methods in handling complex nonlinear relationships and high-dimensional data, this study proposes an efficient and accurate prediction model for college students’ information … …American Journal of Biochemistry and Biotechnology, Vol. 22, Issue 1 · 21 Apr 2026 · 1,695 accessesView PDFCite
Research ArticleOpen accessIn the abstractAccurate Determination of Nonlinear Refractive Index for Some Binary Glass SystemsElSayed MoustafaProblem statement: This study investigates the relation between the nonlinear optical susceptibility (χ(3)) and the ratio (α1/αo-2), then the nonlinear index determination for some binary glass systems. Recently suitable relationship between the oxidation polarizability and the nonlinear optical properties was established for simple oxides glasses. So in this study more attention and investigation is paid to the trend of that … …American Journal of Applied Sciences, Vol. 8, Issue 1 · 31 Jan 2011 · 7,692 accessesView PDFCite
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 abstractThe Investigation of the Relationship among Analyst Following, Managerial Ownership and Firm Valuation: From the Perspective of Agency TheoryI. J. ChenIn this study, the relationship among analyst following, managerial ownership and firm valuation is investigated from the perspective of agency theory by using a nonlinear simultaneous equation model. The data from the Taiwan stock market verify the proposed hypotheses with a nonlinear three-stage least-square procedure. The empirical results show that managerial ownership (serving an internal monitoring function) and number of … …Journal of Social Sciences, Vol. 1, Issue 1 · 31 Mar 2005 · 7,031 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Effect of Using Hysteresis Models (Bilinear and Modified Clough) on Seismic Demands of Single Degree of Freedom SystemsAhmad N. Tarawneh, Sereen A. Majdalaweyh, Bassam Z. MahasnehBased on nonlinear inelastic dynamic analysis of Single Degree Of Freedom systems (SDOF), this work investigates the effect of different parameters on the seismic response of these systems. Generalized SDOF systems that present both short and long period structures are subjected to two sets of synthetic ground motions according to the site condition; stiff rock site and stiff soil one, … …American Journal of Applied Sciences, Vol. 13, Issue 8 · 17 Aug 2016 · 7,729 accessesView PDFCite
Research ArticleOpen accessIn the abstractGenetic Algorithm for Variable and Samples Selection in Multivariate Calibration ProblemsKelton de Souza Santiago, Anderson Silva Soares, Telma Woerle de Lima et al.One of the main problems of quantitative analytical chemistry is to estimate the concentration of one or more species from the values of certain physicochemical properties of the system of interest. For this it is necessary to construct a calibration model, i.e., to determine the relationship between measured properties and concentrations. The multivariate calibration is one of the most successful … …Journal of Computer Science, Vol. 11, Issue 4 · 8 Jun 2015 · 7,381 accessesView PDFCite
Research ArticleOpen accessIn the abstractAerosol Filtration Using Quartz Sand FilterAbbas H. Sulaymon, Yasmen A. MustafaThe cement industry is the major source of cement dust which contains heavy metals like nickel, cobalt, lead, chromium, arsenic and hazardous substances like dioxins and furans. Exposure to these substances can cause health problems to human, animals and vegetation. A continuous pilot scale quartz sand filter was constructed and uses to study the effect of important design parameters (temperature, … …American Journal of Environmental Sciences, Vol. 8, Issue 4 · 20 Jun 2012 · 7,716 accessesView PDFCite
