Research ArticleOpen accessIn the abstractEffect of Load and Routing Protocols on Networks on Chip (NoC): An AnalysisShaily Jain, Chander Prabha, Ayman Noor et al.Communication infrastructure for multi-core Systems-on-Chip (SoCs) is provided by Network-on-Chip (NoC). Point-to-Point (P2P) and bus-based communication systems are NoCs and are two communication channels of NoC that can probably overcome the scalability and performance restrictions of NoC. Latency and throughput are two of the essential characteristic metrics measured for a routing algorithm that affect the performance of a given NoC. … …Journal of Computer Science, Vol. 20, Issue 11 · 29 Aug 2024 · 5,273 accessesView PDFCite
Research ArticleOpen accessIn the abstractImplementing a Hybrid VMD–BiTCN–BiGRU Architecture With Intelligent Optimization for Agricultural Commodity Price Prognostication in Gujarat MarketsJignesh Hirapara, Ratnesh Kumar Namdeo, Ankit Kumar Dubey et al.In the agricultural sector, the prices of pulses require adequate forecasting to plan farming activities, store and market, and guide policy-making. However, the pulse price series is highly volatile, seasonal, nonstationary, and nonlinear, and thus conventional linear time series models are not necessarily very effective. In the suggested framework, the raw price data series is decomposed using Variational Mode Decomposition … …Journal of Computer Science, Vol. 22, Issue 7 · 1 Aug 2026 · 1,021 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Technical, Economic and Environmental Evaluation Study of Utilising Fixed, Single and Dual-Axis Solar Photovoltaic Systems in Boubyan and Failaka Islands in KuwaitDr. Abdulla AL-RashidiImplementing renewable energy technologies, such as solar energy, is an important step towards meeting the increasing demand for electricity in Kuwait. This would be a very helpful way of minimising the negative environmental impacts of conventional power plants. This study reports on the results of a comprehensive technical, environmental and economic evaluation of the use of a grid-connected solar photovoltaic … …American Journal of Engineering and Applied Sciences, Vol. 12, Issue 4 · 9 Nov 2019 · 7,603 accessesView PDFCite
Research ArticleOpen accessIn the abstractAntioxidant Capacity, Total Phenol Contents and Phytochemical Screening of Citrullus colocynthis Crust, Pulp and Seeds ExtractsFaten Hameed Thamer, Noah Thamer, Anhar Alhamzi et al.In this study, the phytochemical screening of Citrullus colocynthis (C. colocynthis) crust, pulp, and seed extracts was studied to evaluate and compare their antioxidant capacities and total phenol contents. C. colocynthis fruit, including crust, pulp, and seed, was extracted using n-hexan, methanol, and 1, 1, 2 trichloroethane, respectively, using a soxhlet. Phytochemical screening, antioxidant capacity using the Ferric-Bipyridine Reducing Capacity … …American Journal of Biochemistry and Biotechnology, Vol. 19, Issue 1 · 16 Jan 2023 · 5,734 accessesView PDFCite
Research ArticleOpen accessIn the abstractUltrastructural and Circadian Morphometric Characteristics of Rat Pinealocytes Under Physiological and Toxic ConditionsAnna I. Anurkina, David A. Areshidze, Maria A. Kozlova, Valery P. ChernikovCarbon tetrachloride (CCl₄) exhibits pronounced neurotoxic effects following acute or chronic exposure. Recent studies indicate that the pineal gland responds to CCl₄ intoxication by altering its secretory function, although detailed ultrastructural changes in pinealocytes remain inadequately investigated. This research addresses the urgent need to elucidate the mechanisms of CCl₄ toxicity on the pineal gland, which could contribute to developing strategies … …OnLine Journal of Biological Sciences, Vol. 26, Issue 2 · 1 Jun 2026 · 1,170 accessesView PDFCite
Research ArticleOpen accessIn the abstractStructural-Topological Synthesis of Planar Mechanisms with Rods and WheelsNicolae Petrescu, Raffaella Aversa, Antonio Apicella, Relly Victoria V. PetrescuToday, robots are increasingly present in the machine building industry, sometimes even in some sections to replace workers altogether, due to the high quality of their work, repetitive, without stopping or pausing, without any manufacturing and assembly scuffs. Additionally, robots do not get sick, do not require medical leave or rest, work faster and better than humans and also support … …Journal of Mechatronics and Robotics, Vol. 2, Issue 1 · 25 Jun 2018 · 6,638 accessesView PDFCite
Research ArticleOpen accessIn the abstractOptimized Biodiesel Production from jatropha curcas oilHaruna Musa, Daniel Eric, Alkhairu Hassan et al.In this study, a mathematical model for the trans-esterification reaction of jatropha curcas seed Oil (JCO) was developed using Response Surface Methodology(RSM) in terms of operational variables such as temperature (50 to 80°C), catalyst concentration (0.7 to 1% in relation to oil mass) and methanol/oil ratio (3:1-9:1), at fixed reaction time (90 min) and mixing intensity. Biodiesel was produced by … …Energy Research Journal, Vol. 12, Issue 1 · 12 Oct 2021 · 7,286 accessesView PDFCite
Research ArticleOpen accessIn the abstractEvaluation of the Effects of the Addition of Salt, Type of Additive and the Shelf Life, on Chemical Composition of Pennisetum purpureum (Schumach) (Maralfalfa) Silages in NigerMaman Lawal Abdoul Aziz, Seydou Korombé Hamza, Djibo Ibrahim et al.Seasonal variations in the quantity and quality of fodder constitute an obstacle to the development of ruminant breeding in Niger. This is why this study was carried out to evaluate the effects of salt addition, shelf life, and type of additive on the chemical composition of Pennisetum purpureum Schumach (Maralfalfa) silages. These aspects were retained because salt, in addition to … …American Journal of Animal and Veterinary Sciences, Vol. 19, Issue 3 · 12 Sep 2024 · 4,720 accessesView PDFCite
