Research ArticleOpen accessEvery word in the titleFlows of Continuous-Time Dynamical Systems with No Periodic Orbit as an Equivalence Class under Topological Conjugacy RelationTahir Ahmad, Tan Lit KenProblem statement: Flows of continuous-time dynamical systems with the same number of equilibrium points and trajectories, and which has no periodic orbit form an equivalence class under the topological conjugacy relation. Approach: Arbitrarily, two trajectories resulting from two distinct flows of this type of dynamical systems were written as a set of points (orbit). A homeomorphism which maps between these … …Journal of Mathematics and Statistics, Vol. 7, Issue 3 · 18 Jul 2011 · 7,254 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleHuman Behavior Classification Using Multi-Class Relevance Vector MachineB. Yogameena, S. Veera Lakshmi, M. Archana, S. Raju AbhaikumarProblem statement: In computer vision and robotics, one of the typical tasks is to identify specific objects in an image and to determine each object’s position and orientation relative to coordinate system. This study presented a Multi-class Relevance Vector machine (RVM) classification algorithm which classifies different human poses from a single stationary camera for video surveillance applications. Approach: First the … …Journal of Computer Science, Vol. 6, Issue 9 · 30 Sep 2010 · 7,390 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleDesign Based on Intra-Class Correlation CoefficientsRobert Lew, Gheorghe DorosProblem statement: Reliability studies are concerned with the study of "consistency" or "repeatability" of measurements. Often times (but not always) the reliability coefficients are Intra-class Correlation Coefficients (ICC). Depending on the design or the conceptual intent of the study there are three types of intra-class correlation coefficients, termed intra-class correlation coefficients Case 1, 2 and 3, for measuring the reliability … …Current Research in Biostatistics, Vol. 1, Issue 1 · 30 Jun 2010 · 18,541 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleAn Alternative Scaling Factor In Broyden's Class Methods for Unconstrained OptimizationMuhammad Fauzi bin Embong, Mustafa bin Mamat, Mohd Rivaie, Ismail bin MohdProblem statement: In order to calculate step size, a suitable line search method can be employed. As the step size usually not exact, the error is unavoidable, thus radically affect quasi-Newton method by as little as 0.1 percent of the step size error. Approach: A suitable scaling factor has to be introduced to overcome this inferiority. Self-scaling Variable Metric algorithms … …Journal of Mathematics and Statistics, Vol. 6, Issue 2 · 2 Jun 2010 · 7,692 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleAn Examination of Teaching Behaviors and Learning Activities in Physical Education Class Settings Taught by Three Different Levels of TeachersHoward Z. Zeng, Raymond W. Leung, Michael HipscherProblem statement: To be an accredited teacher education program, physical education teacher education (PETE) programs must fulfill the national standards established by the National Association for Sport and Physical Education (NASPE). In order to meet the standards, a PETE program needs to have the cooperation of the following three levels of instructors: Specialist Teachers (STs), Inservice Teachers (ITs) and Preservice … …Journal of Social Sciences, Vol. 6, Issue 1 · 31 Mar 2010 · 8,654 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleUML Diagrams Generator: A New CASE Tool to Construct the Use-Case and Class Diagrams from an Event TableMohammad I. Muhairat, Rafa E. Al-Qutaish, Akram A. AbdelqaderProblem statement: Building UML diagrams is a very important and time consuming task for both requirements and design phases. However, some of these diagrams, such as use-case and class diagrams can be considered as a transition between the two phases. Approach: Through this study, the event table will be used to derive the use-case and class diagrams. Results: A new … …Journal of Computer Science, Vol. 6, Issue 3 · 31 Mar 2010 · 8,042 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleA Performance Study of Reactive Multicast Routing Protocols in Virtual Class Room Using Mobile Ad Hoc NetworkS. Vijayaragavan, K. Duraiswamy, B. Kalaavathi, S. MadhaviProblem statement: A great deal of excitement has recently propelled Mobile Learning to the forefront of educational technology. The exponential growth of mobile technology in the recent years, increase in the availability of high-bandwidth network, advances in wireless technologies and popularity of handheld devices, have opened up new accessibility opportunities for education. Approach: Virtual class room using MANET had been … …Journal of Computer Science, Vol. 5, Issue 11 · 30 Nov 2009 · 6,875 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleHybrid CNN-Based Transformer Pipeline With Radiomic Fusion for Multi-Class Lung Cancer DetectionAanchal Vij, Kuldeep Singh Kaswan, Anand NayyarEarly detection of lung cancer remains challenging due to high intra-class variation and inter-class similarity in Computed Tomography (CT) images. In this paper, we propose a hybrid deep learning model that combines convolutional, attention-based, and transformer-guided representations to address these challenges in multi-class lung cancer classification. For deep feature extraction, we use the EfficientNetV2-S architecture augmented with a Convolutional Block … …Journal of Computer Science, Vol. 22, Issue 6 · 3 Jun 2026 · 1,528 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleA Comparative Study of Resampling, Cost-Sensitive, and Ensemble Techniques for Handling Class Imbalance in Indonesian Financial DataGunawan Kurnia, Ditdit Nugeraha UtamaHandling class imbalance is a critical challenge in machine learning applications, particularly in financial domains where minority instances often represent significant anomalies such as fraud or audit risks. Various oversampling and undersampling methods were tested, alongside cost-sensitive adjustments and ensemble models including Random Forest, AdaBoost, Gradient Boosting, and XGBoost. The evaluation, based on 10-fold stratified cross-validation and performance metrics such … …Journal of Computer Science, Vol. 22, Issue 2 · 27 Feb 2026 · 1,874 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleCulture and the Changing Food Consumption Among the Malay Middle ClassKartini Aboo Talib, Zaireeni Azmi, Hanim Ismail, Nurul Asmaa RamliThis article examines the consumption of foods among the middle-class Malays in Malaysia and the progress of food products that have been constructed to meet the halal logo and certification. This article challenges the standard view of the Malay middle class, predominantly Muslim that they are traditional and hesitant to accept changes in food consumption due to religion and culture. … …Journal of Social Sciences, Vol. 18, Issue 1 · 2 Mar 2022 · 8,078 accessesView PDFCite
