Research ArticleOpen accessIn the keywordsResearch of Modular Object Oriented Dynamic Learning Environment E-Learning on Social Study for Elementary School StudentsTian-Syung Lan, Shu-Chun ChiuProblem statement: As the progress of digital technology, involving e-learning into curriculum becomes a novel trend. In general, the teaching practice of social study for elementary school students in Taiwan still depends on teacher’s one-way instruction. It’s difficult to activate students’ motivation within the limited course time. Approach: This study is proposed to recognize how e-learning improves teaching and learning … …Journal of Mathematics and Statistics, Vol. 7, Issue 2 · 18 May 2011 · 7,731 accessesView PDFCite
Research ArticleOpen accessIn the keywordsRandom Forests for Online Intrusion Detection in Computer NetworksHeitor Scalco Neto, Wilian Soares Lacerda, Rafael Verão FrançozoThis study proposes a methodology to build an Online Network Intrusion Detection System by using the Computational Intelligence technique called Random Forests and an API to preprocess the network packets. The experiments were carried out from two network traffic databases: The ISCX (i); and a test database (ii) created with the proposed API in our own network environment. The results … …Journal of Computer Science, Vol. 17, Issue 10 · 19 Oct 2021 · 6,955 accessesView PDFCite
Review ArticleOpen accessIn the keywordsA Systematic Review of Artificial Intelligence and Deep Learning Approaches for Cocoa Pod Disease DetectionHenry Techie-Menson, Michael Asante, Yaw Marfo Missah et al.Cocoa pod diseases destroy an estimated 700,000 metric tons of cocoa annually, threatening 40–50 million smallholder farmers across tropical regions. Accurate field diagnosis remains constrained by symptom similarity, labour-intensive scouting, and limited specialist access in remote communities. This paper presents a PRISMA-guided systematic review of 25 peer-reviewed studies on automated cocoa pod disease detection and classification (2016–2026), addressing architectural approaches, … …Journal of Computer Science, Vol. 22, Issue 8 · 8 Sep 2026 · 733 accessesView PDFCite
Review ArticleOpen accessIn the keywordsA Survey of Quadratization Methods Used in QUBO Formulations and their Usage in Quantum and Digital AnnealingGeethika Prabhath, Anuradha Mahasinghe, Nalin Ranasinghe, Kasun De ZoysaQuantum annealing is a metaheuristic method aimed at finding the global minimum of a pseudo-Boolean quadratic function. To solve a problem by a quantum annealer, it must be restated as a QUBO (quadratic unconstrained binary optimization) problem, the standard format acceptable to an annealer. However, there are many natural problems that turn out be of cubic or higher order, yet … …Journal of Computer Science, Vol. 22, Issue 1 · 16 Feb 2026 · 2,554 accessesView PDFCite
Research ArticleOpen accessIn the keywordsLow Power Modulo 2n+1 Adder Based on Carry Save Diminished-One Number SystemSomayeh Timarchi, Omid Kavehei, Keivan NaviModulo 2n +1 adders find great applicability in several applications including RNS implementations. This paper presents a new number system called Carry Save Diminished-one for modulo 2n+1 addition and a novel addition algorithm for its operands. In this paper, we also present a novel architectures for designing modulo 2n+1 adders, based on parallel-prefix carry computation units. CMOS implementations reveal the … …American Journal of Applied Sciences, Vol. 5, Issue 4 · 30 Apr 2008 · 7,561 accessesView PDFCite
Research ArticleOpen accessIn the keywordsHead Gesture Analysis using Matrix Group Displacement AlgorithmMahmoud Z. IskandaraniA novel algorithm for head gestures interpretation is designed and tested. The designed system carries out gesture detection and recognition using the MGDA algorithm, which implements random sampling and importance sampling, such technique can track head poses and estimate head positions. Problem statement: Head position is an important indicator of a person’s focus of attention, which can be used as … …Journal of Computer Science, Vol. 6, Issue 11 · 23 Oct 2010 · 7,247 accessesView PDFCite
Research ArticleOpen accessIn the keywordsUsing Expert Evaluation to Assess the Implementation of Persuasive Design in e-CommerceAmjad Al-mutairi, Majed AlshamariIt has been argued that the use of persuasive design in e-commerce applications has a positive impact on user behavior and on converting browsers into buyers. Effective e-commerce applications successfully gain customers’ trust. Thus, it is important for designers to know how to apply and embed persuasive design models in e-commerce applications. This study aimed to assess the extent to … …Journal of Computer Science, Vol. 16, Issue 10 · 18 Oct 2020 · 6,691 accessesView PDFCite
Research ArticleOpen accessIn the keywordsOne-Match and All-Match Categories for Keywords Matching in ChatbotAbbas Saliimi Lokman, Jasni Mohamad ZainProblem statement: Artificial intelligence chatbot is a technology that makes interactions between men and machines using natural language possible. From literature of chatbot’s keywords/pattern matching techniques, potential issues for improvement had been discovered. The discovered issues are in the context of keywords arrangement for matching precedence and keywords variety for matching flexibility. Approach: Combining previous techniques/mechanisms with some additional adjustment, … …American Journal of Applied Sciences, Vol. 7, Issue 10 · 31 Oct 2010 · 8,165 accessesView PDFCite
Research ArticleOpen accessIn the keywordsEfficient Approach for Security Information Retrieval by Using GridHameed Ullah KhanProblem statement: This article communicated an approach for determining the exact location/position of the target(s) (human) by applying Grid (matrix) method. Approach: The Main-Grid in-return further grouped into Mini-Grids; which will provide the target(s) information. To accomplish this idea the whole scenario is divided into three phases. Results: In the first phase data is collected from the targeted area, in … …Journal of Computer Science, Vol. 5, Issue 12 · 31 Dec 2009 · 6,952 accessesView PDFCite
