Research ArticleOpen accessEvery word in the titleThe Role of Electrical Pulse Shapes in Electrical and Optical Chromatic Dispersion CompensationMohammad Syuhaimi Ab-Rahman, Majid MoghaddasiProblem statement: The performance of the optical network is highly dependent to Chromatic Dispersion (CD). CD has been a big issue when higher bitrate or longer distance is desired. Many methods have been represented to mitigate or eliminate this phenomenon. A wide range of optical and electrical compensation has been investigated. Approach: In this study we evaluate the efficiency of … …Journal of Computer Science, Vol. 7, Issue 12 · 25 Oct 2010 · 6,587 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleRetrieval of Similar Shapes Under Affine Transform Using Affine Length ParameterizationA. Lakehal, O. El Beqqali, O. Ait ZemzamiProblem statement: In this study, a new descriptor for shape retrieval under affine transformations had been proposed; the affine length parameterization was used in this approach. Approach: The zero crossing of affine curvature was used to extract a descriptor of shapes in database. For each two successive zero crossing points we extract two parameters: the first parameter was a maximal … …Journal of Computer Science, Vol. 6, Issue 10 · 30 Aug 2010 · 7,260 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleOptimized Cloud Load Balancing Using Deep Q-Learning With Inverted S-Shaped Hierarchical Reverse Superb Fairy-Wren OptimizationB. R. Yogeetha, S. P. AnandarajCloud computing offers a scalable and cost-effective platform by providing on-demand access to shared computational resources. However, effective load balancing is essential to maintain optimal performance and maximize resource utilization for ensuring even distribution of network traffic across servers, preventing overload, improving response time and enhancing the system reliability. This manuscript proposes the Deep Q-Network with Inverted S-shaped Hierarchical Reverse … …Journal of Computer Science, Vol. 22, Issue 6 · 4 Jun 2026 · 1,504 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleFORCED CONVECTION HEAT TRANSFER, FLOW CONFIGURATION AND THERMAL PERFORMANCE IN A SQUARE CHANNEL WITH MODIFIED V-SHAPED BAFFLESAmnart Boonloi, Withada JedsadaratanachaiThe influences of modified V-shaped baffle in a square channel for heat transfer and thermal performance enhancement are presented numerically in three Dimensional (3D). The V-shaped baffles are modified in order to comfortable to installation in the square channel. The plates are used for clamping on both the upper and lower V-shaped baffles resulting the modified V-shaped baffle like orifice … …Journal of Mathematics and Statistics, Vol. 10, Issue 2 · 7 Apr 2014 · 6,692 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleA NEW METHOD FOR 3D SHAPE INDEXING AND RETRIEVAL IN LARGE DATABASE BY USING THE LEVEL CUTA. Lakehal, M. Elkhal, K. SatoriIn this study, we propose a new method for indexing and retrieval of 3D models in large databases based on binary images extracted from the 3D object called &#34level cut&#34 LC. These cuts are obtained by the intersection of the set of the plans with the 3D object. A set of equidistant parallel plans generates by the intersection with the … …Journal of Computer Science, Vol. 10, Issue 10 · 22 May 2014 · 6,827 accessesView PDFCite
Review ArticleOpen accessEvery word in the titleNew Researches Examines the Wing Shapes to Reduce Vortex and WakeNicolae Petrescu, Raffaella Aversa, Antonio Apicella, Florian Ion Tiberiu PetrescuIt is common to see clouds in the form of the sky, known as contrails, which are behind the engines of a reaction plan. What is not always visible is a wind whirl that comes out of the top of each wing - like two small horizontal tornadoes - leaving behind a turbulent awakening behind the vehicle. Awakening is a … …Journal of Aircraft and Spacecraft Technology, Vol. 2, Issue 1 · 19 Jun 2018 · 7,422 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleDual-Branch Shape Texture Learning With Pyramid Residual and Sobel Edge Layers for Rice Variety ClassificationM Pradeep, M SiddappaAutomated rice variety classification categorizes rice types based on features, such as grain texture, shape, color, and size. Traditional handcrafted feature-based models fail at rice classification due to lighting variations, background noise, and environmental conditions, leading to overlapping visual characteristics and frequent misclassification. To address these challenges, this research proposes a novel Dual-Branch Convolutional Neural Network with Pyramid Residual Units … …Journal of Computer Science, Vol. 22, Issue 9 · 24 Sep 2026 · 632 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleThe Effects of Oil Film Shape on Piston Ring and Liner Tribology Under Mixed LubricationAbbas Razavykia, Cristiana Delprete, Eugenio Brusa, Yaser HosseiniMechanical power loss reduction at lubricated reciprocating and rotating components is recognized as an approach to improve the efficiency and to reduce the emissions of Internal Combustion Engines (ICEs). To achieve these goals, the instantaneous investigation of lubrication characteristics is required. Piston ring pack is of paramount importance as it is known as major contributor to frictional losses and energy … …American Journal of Engineering and Applied Sciences, Vol. 14, Issue 4 · 10 Nov 2021 · 6,533 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleBiomechanically Inspired Shape Memory Effect Machines Driven by Muscle like Acting NiTi AlloysRaffaella Aversa, Francesco Tamburrino, Relly Victoria V. Petrescu et al.The research shows a bioinspired approach to be adopted to design of systems based on Shape Memory Alloys (SMAs), a class of Smart Materials that has in common with muscles the capability to react to an impulse (thermal for SMAs) with a contraction. The biomechanically inspired machine that is discussed in the paper refers to the antagonistic muscles pairs, which … …American Journal of Applied Sciences, Vol. 13, Issue 11 · 24 Nov 2016 · 9,114 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleRHEOLOGICAL PROPERTIES OF PADDY SOIL UNDER VARIOUS PRESSURE, WATER CONTENT AND TOOL SHAPESI. A. Mari, C. Ji, F. A. Chandio et al.In this study Burger’s four element model was used to analyze rheological parameter of paddy soil of the Southern China. Two types of tool shape include circular shape (with an area of 12.56 cm2) and rectangular shape (with an area of 12.56 cm2) were use to measure the rheological parameter of paddy soil under different loading pressure (7.65, 10.20 and … …American Journal of Agricultural and Biological Sciences, Vol. 9, Issue 1 · 14 Dec 2013 · 7,518 accessesView PDFCite
