Research ArticleOpen accessIn the abstractAn Integrated Quantitative Assessment Model For Usability EngineeringHaidar S. Jabbar, T. V. Gopal, Sattar J. AboudMany different quantitative assessment models have been proposed to measure and report the usability of a general software product for various business and design purposes. However, there are several problems coupled with existing models that consequently bias and affect the process and results of the usability assessment. Moreover, they do not aid their usage by analysts who are not experienced … …Journal of Computer Science, Vol. 3, Issue 5 · 31 May 2007 · 6,706 accessesView PDFCite
Research ArticleOpen accessIn the abstractAdaptive Cross-Validation Under Concept Drift for Time Series ForecastingKunjira Kingphai, Prapakorn Kanjina, Kamol Sanittham, Wacharong WongsanurakTime-series forecasting often involves non-stationary data, making i.i.d. validation unreliable and fixed-window protocols vulnerable to leakage and biased error estimates. We propose Adaptive Time-Series Cross-Validation (ATSCV), a drift-aware evaluation framework that uses statistical change-point detection to partition each series into contiguous, approximately stationary regimes, followed by forward-chaining folds that respect those boundaries. By aligning train–validation splits with distributional changes (with … …Journal of Computer Science, Vol. 22, Issue 7 · 7 Jul 2026 · 1,502 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Optimized Extreme Learning Machine (GA-OELM) for DDoS Attack Detection in Cloud EnvironmentMeryem Ec-Sabery, Adil Ben Abbou, Abdelali Boushaba et al.The widespread adoption of cloud computing has increased the attack surface and raised significant security concerns. A Distributed Denial of Service (DDoS) is a serious attack that depletes the network and server resources in cloud computing, causing service downtime or reduced performance. Therefore, defending against DDoS attacks becomes an urgent need. In this present paper, we propose an Optimized Extreme … …Journal of Computer Science, Vol. 21, Issue 1 · 19 Dec 2024 · 5,044 accessesView PDFCite

Yasir Arafat, Sultana Akter, Mohammad Jonaed Kabir et al.The purpose of this research is to assess the contribution of information system quality to organizational effectiveness and financial reporting quality prepared by commercial banks in Bangladesh. For this purpose, a survey is conducted to gather information from 240 people by purposefully sampling method about their experiences in information system quality, the effectiveness of their organization, and the financial reporting … …Journal of Computer Science, Vol. 20, Issue 12 · 24 Nov 2024 · 4,633 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Comparative Analysis of Smote and CSSF Techniques for Diabetes Classification Using Imbalanced DataBashar Hamad Aubaidan, Rabiah Abdul Kadir, Mohamad Taha IjabDiabetes, a prevalent chronic metabolic disorder, poses a significant burden on healthcare systems worldwide. Accurate and timely diagnosis is crucial for effective management and complication prevention. Machine learning presents a promising solution but often faces challenges due to class imbalance within datasets, particularly the underrepresentation of diabetic cases. To address this issue, we introduce Cluster-based Synthetic Sample Filtering (CSSF), a … …Journal of Computer Science, Vol. 20, Issue 9 · 22 Jul 2024 · 5,005 accessesView PDFCite
Research ArticleOpen accessIn the abstractStatistical Tool for Testing Agreement Level on Continuous DatasetsBasavarajaiah Mariyappa Doddagangavadi, B. Narasimha Murthy, Netra RajpurohitVarious analytical studies explored the new innovation for testing agreement level in medical and life sciences which can be simulated by Cohen ‘κ’ based on the practical applications. From the past medical literature, many authors suggested that, there is some disproportion research gaps that exists in the statistical methods for measuring the agreements between two or more observers from ‘Cohen … …Current Research in Biostatistics, Vol. 11, Issue 1 · 19 May 2021 · 11,787 accessesView PDFCite
Research ArticleOpen accessIn the abstractSuVashantor: English to Bangla Machine Translation SystemsMahjabeen Akter, M. Shahidur Rahman, Muhammed Zafar Iqbal, Mohammad Reza SelimThis paper presents the system description of Machine Translation (MT) systems for English-Bangla language pair. Our goal was to create two benchmark MT systems that produce a better quality translation and comparatively higher evaluation score than existing MT systems for English to Bangla. In our experiments, we implemented two baseline MT systems using both statistical and neural methods for the … …Journal of Computer Science, Vol. 16, Issue 8 · 16 Aug 2020 · 7,451 accessesView PDFCite
Research ArticleOpen accessIn the abstractOn Using Conventional and TL moments for the Estimation of a Mixture of Exponential Distributions, A Theoretical ReviewHabib Ahmed ElsayirThis paper focuses on derivation of a mixture of exponential distribution and Linear Moments (LM) and Trimmed Linear moments (TL) is derived for estimation of its parameters. A comparison was made between L-moments, TL-moments of two component mixture of exponential distributions and conventional moments. In intensive simulation study, empirical study results are in the favor of conventional moments, the reason … …American Journal of Applied Sciences, Vol. 17, Issue 1 · 23 May 2020 · 7,094 accessesView PDFCite
Research ArticleOpen accessIn the abstractEvaluation of the Texas Feed Yard Workforce: Survey of Stockperson Attitudes and Perceptions towards Euthanasia, Animal Care and Employee ValueEmily E. Ridge, Ron Gill, Courtney L. DaigleA survey was administered to Texas cattle feedyard employees (n =111) from 31 different operations measuring stockperson perception, job satisfaction and socioeconomic status using Likert statements and multiple-choice questions. Differences among employment roles (manager, pen rider, processor (those who vaccinate and implant incoming calves), doctor (non-veterinarians)) were evaluated using a Kruskal-Wallis test followed by a Multiple Comparison procedure. Managers strongly … …American Journal of Animal and Veterinary Sciences, Vol. 14, Issue 2 · 28 May 2019 · 7,748 accessesView PDFCite
Research ArticleOpen accessIn the abstractSex Dimorphism in the Fgf21 Gene Expression in Liver and Adipose Tissues is Dependent on the Metabolic ConditionNadezhda Bazhan, Tatiana Jakovleva, Natalia Balyibina et al.Fibroblast growth factor-21 (FGF21) beneficially affects carbohydrate and lipid metabolism. Previously, a sex-specific activation of Fgf21 expression was observed in humans and animals with metabolic diseases. It is unknown whether the sex differences in the Fgf21 expression are manifested in response to the natural physiological situations of fasting and refeeding. The aim of this work was to determine liver, White … …OnLine Journal of Biological Sciences, Vol. 19, Issue 1 · 29 Jan 2019 · 8,158 accessesView PDFCite
