Research ArticleOpen accessEvery word in the titleSome Kinds of Distributional Chaos for Non-Autonomous Discrete SystemsYongxi Jiang, Tianxiu Luand, Xiaofang YangIn this study, several kinds of distributional chaos are defined in a non-autonomous discrete system and the chaotic behavior of the mapping sequence fn, ∞ = (fn, fn+1···), ∀n ∈ N (N is a set of natural numbers) is studied. Then, the uniform distributional chaos and maximal distributional chaos of the compound system deduced by f1, ∞ are discussed …Journal of Mathematics and Statistics, Vol. 17, Issue 1 · 4 Nov 2021 · 6,260 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleAutonomous Online Predictive Monitoring System for Hazardous Air Pollution Prediction: A Case StudyAyed A. Salman, Fawaz S. Al-AnziEnvironment is increasingly becoming an important issue in the world of politics and global economy as well as people's life. Environmental deterioration resulted from human activity; misuse of natural resources. Pollution is now a global issue that ecologically, economically and politically requires imminent, intelligent and global solutions. This paper present findings and results of a real project, supported by the … …American Journal of Environmental Sciences, Vol. 12, Issue 3 · 31 May 2016 · 7,527 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleVision-Based Real-Time Positioning and Autonomous Navigation System Using Mobile Robot in Indoor EnvironmentsDiop Mamadou, Lim Chot Hun, Lim Tien Sze, Ong Lee YengResearch toward unmanned mobile robot navigation has gained significant importance in the last decade due to its potential applications in the location-based services industry. The increase in construction of large space indoor buildings has made difficulty for humans to operate within such environments. In this study, a mobile robot's indoor navigation algorithm is developed with vision cameras. Using two monocular … …American Journal of Applied Sciences, Vol. 13, Issue 5 · 17 May 2016 · 7,317 accessesView PDFCite
Review ArticleOpen accessIn the keywordsBoeing's Autonomous Military AircraftRelly Victoria Virgil PetrescuBoeing will build a self-propelled military aircraft to accompany US combat aircraft during missions. Boeing's autonomous airplane will achieve superior flying performance to those pilots even with the most modern aircraft. If technology advances and becomes more accessible to civilians, why would not this happen in the military domain? US, Russian, Australian and British armies have already been using advanced … …Journal of Aircraft and Spacecraft Technology, Vol. 3, Issue 1 · 17 Jun 2019 · 6,984 accessesView PDFCite
Research ArticleOpen accessIn the keywordsEfficient Design of a Photovoltaic Water Pumping and Treatment SystemAbderrahmen Ben Chaabene, Med Faouzi Elkaroui, Anis SellamiThrough the world, the exploitation of solar energies knew a strong growth these last years. It is interesting to exploit them on the place of consumption, by directly transforming into heat, or in electricity according to needs and especially in remote areas where power from utility is not available or is too costly to install. The use of photovoltaic sources … …American Journal of Engineering and Applied Sciences, Vol. 6, Issue 2 · 4 Jul 2013 · 7,628 accessesView PDFCite
Research ArticleOpen accessIn the keywordsSM-SCAM YOLO: Enhancing Object Detection with Multi-Scale Module and Spatial Channel Attention MechanismShanmuga Sundari Mariyappan, Kayalvizhi Mohan, K. B. K. S. DurgaDetecting tiny objects remains a significant hurdle in computer vision, primarily due to scale variation, occlusion, and the loss of detail in low-resolution features. Although YOLO-based detectors are popular for their speed and efficiency in real-time tasks, they often struggle with accurately identifying small objects because of information loss during downsampling. This study introduces an improved YOLO-based model that integrates … …Journal of Computer Science, Vol. 21, Issue 6 · 12 Jun 2025 · 3,921 accessesView PDFCite
Research ArticleOpen accessIn the keywordsAN EFFICIENT AUTONOMOUS KEY MANAGEMENT WITH REDUCED COMMUNICATION/COMPUTATION COSTS IN MOBILE AD HOC NETWORKM. Devi, S. Chenthur PandianA primary concern in Mobile Ad Hoc Networks (MANETs) is security. Secret sharing is an effective way to distribute a secret among n parties, where each party holds one piece of the secret. A number of key management schemes have been proposed for MANETs. However the secret sharing to control key hierarchy needs larger message transmission costs in many techniques. … …Journal of Computer Science, Vol. 9, Issue 10 · 5 Sep 2013 · 6,778 accessesView PDFCite
Research ArticleOpen accessIn the keywordsHeart Rate Variability Analysis in Different Age and Pathological ConditionsM.E.S. Chelladurai, N. KumaravelProblem statement: Heart Rate Variability (HRV) has been used as a measure of mortality primarily with patients who had undergone cardiac surgery. The analysis of Heart Rate Variability (HRV) demands specific capabilities which are not provided either by parametric or nonparametric conventional estimation methods. The Empirical Mode Decomposition (EMD) adaptively estimates the Intrinsic Mode Functions (IMFs) of nonlinear nonstationary signals. … …Journal of Computer Science, Vol. 7, Issue 10 · 4 Aug 2011 · 6,818 accessesView PDFCite
Research ArticleOpen accessIn the abstractSEAchain: A Privacy-Preserving Dual-Credential Model on BlockchainS. Balachander, A. MuruganAll facets of daily life are now impacted by transaction data. The complex and heterogeneous network created by millions of users, devices, online services, and applications makes digital identity management more difficult. Users can maintain control over their personal information via distributed identity, a potentially useful model for resolving identity issues. Nevertheless, current state-of-the-art techniques are inappropriate because of persistent … …Journal of Computer Science, Vol. 22, Issue 5 · 25 May 2026 · 1,310 accessesView PDFCite
Research ArticleOpen accessIn the abstractMulti-Agent Energy Allocation Optimization in Local Energy Communities: A Comparative StudyAmira Dhorbani, Dhaker Abbes, Benoît Robyns, Kahina Hassam OuariThe growing diversity of energy demands, combined with the integration of renewable and distributed energy systems, calls for more adaptive energy management strategies. This study presents a comparative simulation-based analysis of three energy management approaches applied to a local energy community: A Multi-Agent System (MAS), a centralized rule-based method, and a game-theory-based optimization using the Alternating Direction Method of Multipliers … …American Journal of Applied Sciences, Vol. 22, Issue 1 · 30 Dec 2025 · 3,381 accessesView PDFCite
