Research ArticleOpen accessEvery word in the titleFramework for the Adaptive Learning of Higher Education Students in Virtual Classes in Peru Using CRISP-DM and Machine LearningMaryori Bautista, Sebastian Alfaro, Lenis WongDuring the COVID-19 pandemic, virtual education played a significant role around the world. In post-pandemic Peru, higher education institutions did not entirely dismiss the online education modality. However, this virtual education system maintains a traditional teaching-learning model, where all students receive the same content material and are expected to learn in the same way; as a result, it has not … …Journal of Computer Science, Vol. 20, Issue 5 · 26 Feb 2024 · 5,893 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleThe Impact of Virtual Classes on Students’ Performance in Open Learning Environments: The Case of Arab Open University, Saudi ArabiaKhaled Suwais, Ali AlshahraniOpen learning aims to deliver different educational services and activities for learners throughout an organised set of policies and procedures. The ultimate objective of such policies is to minimise the geographical and time limitations that might affect the students’ performance during his or her academic life. The Arab Open University in Saudi Arabia is one of the leading universities that … …Journal of Computer Science, Vol. 14, Issue 1 · 3 Jan 2018 · 8,900 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleMining Functional Dependency from Relational Databases Using Equivalent Classes and Minimal CoverJalal Atoum, Dojanah Bader, Arafat AwajanData Mining (DM) represents the process of extracting interesting and previously unknown knowledge from data. This study proposes a new algorithm called FD_Discover for discovering Functional Dependencies (FDs) from databases. This algorithm employs some concepts from relational databases design theory specifically the concepts of equivalences and the minimal cover. It has resulted in large improvement in performance in comparison with … …Journal of Computer Science, Vol. 4, Issue 6 · 30 Jun 2008 · 6,879 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEstόria: A Framework for Code and Execution Reuse between Test ClassesLucas Pereira da Silva, Patrícia VilainManual implementation of test code can lead to maintainability problems such as test code duplication. Strategies to avoid test code duplication and to promote test code reuse exist in the literature. However, it becomes increasingly difficult to apply these strategies as the system evolves and the number of test increases. In this study, we present a novel strategy to reuse … …Journal of Computer Science, Vol. 17, Issue 2 · 11 Feb 2021 · 7,025 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleA New Database Encryption Model Based on Encryption ClassesKarim El Bouchti, Soumia Ziti, Fouzia Omary, Nassim KharmoumData encryption is one of the advanced measures used to consolidate data security inside Databases. It is an essential technique to protect data against theft, disclosure or modification from different typologies of attacks. In this work, we will propose a new database encryption model. It is based on a novel concept called "Encryption Classes". The proposed model is full compared … …Journal of Computer Science, Vol. 15, Issue 6 · 26 Jun 2019 · 7,710 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleAn Upper Bound to the Number of Conjugacy Classes of Non-Abelian Nilpotent GroupsBilal Al-Hasanat, Awni Al-Dababseh, E. Al-Sarairah et al.The number of conjugacy classes of symmetric group, dihedral group and some nilpotent groups is obtained. Until now, it has not been obtained for all nilpotent groups. Although there are some lower bounds to this value, there is no non-trivial upper bound. This paper aims to investigate an upper bound to this number for all finite nilpotent groups. Moreover, the … …Journal of Mathematics and Statistics, Vol. 13, Issue 2 · 23 May 2017 · 7,552 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleSocial Interactions for Academic Purposes in Literature Classes for Non English SpeakersAi Chun YenProblem statement: This study reports how Learning Communities (LCs) and Online Learning Communities (OLCs) can improve Taiwanese EFL students’ lack of Social Interactions (SIs) and acdemic skills in literature classes (Y1, N = 40) by involving freshmen in a social process that encourages student-student and student-instructor discussion, interpretation, production and negotiation. Approach: The data collected from the database of the … …Journal of Social Sciences, Vol. 8, Issue 3 · 16 Jul 2012 · 7,281 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleOn the Relationship between Classes P and NPAnatoly D. PlotnikovProblem statement: In this study we discuss the relationship between the known classes P and NP. We show that the difficulties in solving problem “P versus NP” have methodological in nature. An algorithm for solving any problem is sensitive to even small changes in its formulation. Conclusion/Recommendations: As we will show in the study, these difficulties are exactly in the … …Journal of Computer Science, Vol. 8, Issue 7 · 16 May 2012 · 10,601 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleDynamic Bandwidth Allocation for Multiple Traffic Classes in IEEE 802.16e WiMax Networks: A Petrinet ApproachS. Geetha, R. JayaparvathyProblem statement: WiMAX supports multiple types of traffic such as data, voice and video. Each flow requires a certain minimum bandwidth to achieve its QoS. Bandwidth allocation to traffic classes should be in such a way that fairness criteria is met with. Hence, we propose a dynamic bandwidth allocation mechanism to achieve fair and efficient allocation. Approach: We present a … …Journal of Computer Science, Vol. 7, Issue 11 · 6 Sep 2011 · 7,105 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleOn Certain Classes of Multivalent Analytic FunctionsRabha W. Ibrahim, Maslina DarusProblem statement: By means of the Hadamard product (or convolution), new class of function of power order was formed. This class was motivated by many authors namely MacGregor, Umezawa, Darus and Ibrahim and many others. The class indeed extended in the form of integral operator due to the work of Bernardi, Libera and Livingston. Approach: A new class of multivalent … …Journal of Mathematics and Statistics, Vol. 6, Issue 3 · 30 Sep 2010 · 7,441 accessesView PDFCite
