Research ArticleOpen accessIn the abstractHeat Generation/Absorption Effect on Natural Convection Flow in a Vertical Annulus with Time-Periodic Boundary ConditionsMichael O. Oni, Basant K. JhaThe role of heat generation/absorption on natural convection flow formation in a vertical annulus with prescribed time-periodic heating is investigated in this article. The governing continuity, momentum and energy equations are converted into ordinary differential equation using suitable transformations and closed form expressions are obtained for temperature distribution, velocity profile, Nusselt number, skin friction and mass flow rate in terms … …Journal of Aircraft and Spacecraft Technology, Vol. 3, Issue 1 · 27 Jul 2019 · 6,340 accessesView PDFCite
Research ArticleOpen accessIn the abstractTotal Conductivity of Calcium Iron Borate Glasses Using an Empirical FormulaHossam M. Gomaa, Saeid M. Elkatlawy, Ahmed H. El-DosokeySamples of calcium borate glasses containing iron ions have been prepared with three different concentrations of both boron and iron oxides. X-ray diffraction spectroscopy was performed and results revealed that samples are in good glassy state, with high homogeneity and short range ordered structure. Electrical conductivity was experimentally measured in the temperature range from 300 to 553 K. Conductivity results … …International Journal of Structural Glass and Advanced Materials Research, Vol. 3, Issue 1 · 21 May 2019 · 7,098 accessesView PDFCite
Research ArticleOpen accessIn the abstractDynamic Models for Rigid Memory MechanismsRelly Victoria Virgil PetrescuThe paper presents a dynamic model that works with variable internal damping, applicable directly to rigid memory mechanisms. If the problem of elasticity is generally solved, the problem of system damping is not clear and well-established. It is usually considered a constant "c" value for the internal damping of the system and sometimes the same value c and for the … …Journal of Mechatronics and Robotics, Vol. 3, Issue 1 · 6 May 2019 · 5,983 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Approach to the Performance and Efficiency Power Analysis on Embedded Devices Using AsteriskAdauto Cavalcante Menezes, Toniclay Andrade Nogueira, Edward David Moreno Ordonez, Admilson de Ribamar Lima RibeiroVoice over IP (VoIP) communication will dominate the computing world for years to come. In order to perform VoIP communication, it is necessary to encode and decode the voice. This process consumes the main computational resources, as an example, it is possible to mention the processor and memory. The telecommunication industries provide equipment with high purchasing prices, which makes the … …Journal of Computer Science, Vol. 14, Issue 7 · 2 Aug 2018 · 8,265 accessesView PDFCite
Research ArticleOpen accessIn the abstractMechanically Stimulated Osteoblast Cells GrowthRaffaella Aversa, Antonio Apicella, Francesco Tamburrino, Florian Ion Tiberiu PetrescuThe bones need to be built and then permanently restored to keep them functioning properly. Considering the multiple bone functions, their vitality is essential both to maintain the body and move it and to maintain its health and vigor. When most bones begin to age and have no vital function, the man also begins to age, lose water, minerals, electrolytes, … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 2 · 19 Jun 2018 · 7,888 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Systematic Review of Metaheuristic-Metaheuristic (MH-MH) Hybridizations for OptimizationAugustina Dede Agor, Frank Kataka Banaseka, Prince Silas Kwesi Oberko et al.This systematic review following the PRISMA framework analyzes metaheuristic-metaheuristic (MH-MH) hybridizations published between January and October 2024 to uncover patterns of algorithmic dominance, functional roles and integration strategies, metaphor-based partnerships, domain mappings and evaluation orientations. Frequency mapping of 105 canonical algorithms identified Particle Swarm Optimization (PSO), Grey Wolf Optimizer (GWO), and Whale Optimization Algorithm (WOA) as the three most recurrent … …Journal of Computer Science, Vol. 22, Issue 2 · 4 Mar 2026 · 2,188 accessesView PDFCite
Research ArticleOpen accessIn the abstractUnsupervised Cosegmentation Model based on Saliency Detection and Optimized Hue Saturation Value Features of SuperpixelsRasha Shoitan, Mona M. MoussaSegmenting out the foreground from a single image remains a challenge in computer vision. Image co-segmentation has been used recently to alleviate the single image segmentation by exploiting the information of the common object to be segmented from a group of images having the same object. This research proposes an unsupervised co-segmentation technique based on saliency detection and optimized features … …Journal of Computer Science, Vol. 17, Issue 7 · 3 Aug 2021 · 7,009 accessesView PDFCite
Research ArticleOpen accessIn the abstractCONTENT BASED BATIK IMAGE RETRIEVALA. Haris Rangkuti, Agus Harjoko, Agfianto Eko PutroContent Based Batik Image Retrieval (CBBIR) is an area of research that focuses on image processing based on characteristic motifs of batik. Basically the image has a unique batik motif compared with other images. Its uniqueness lies in the characteristics possessed texture and shape, which has a unique and distinct characteristics compared with other image characteristics. To study this batik … …Journal of Computer Science, Vol. 10, Issue 6 · 27 Jan 2014 · 7,426 accessesView PDFCite
Research ArticleOpen accessIn the abstractNutrient and the Mind-Body Axis, in Relation to Omega-3 Fatty Acids and Amino AcidsToru Takahashi, Eri Toda, Ram B. Singh et al.Noncommunicable Diseases (NCDs); obesity, type 2 diabetes mellitus, Cardiovascular Diseases (CVDs) and cancer have become major health problems in both developing and developed countries. Physical inactivity and increased intake of energy rich proinflammatory foods in association with genetic predisposition are common primary risk factors for these problems. Mind-body interactions and mechanisms in relation to hypothalamus neurotransmitters and vagus nerve have … …Current Research in Medicine, Vol. 3, Issue 1 · 17 Feb 2012 · 7,323 accessesView PDFCite
