Research ArticleOpen accessPhrase in the titleA Simplified Two-Dimentional Unit Cell Model for Analyzing the Transverse Shear Stiffness of Three-Dimentional Truss-Like Core Sandwich BeamSuphattharachai Chomphan, Manit LeekitwattanaProblem statement: In structural analysis using finite element software, a complex three-dimensional model affects the speed of calculation time. A simplified two-dimensional model should be used for analyzing structural responses to reduce the calculation time. Approach: This study presents a study on the analysis of the transverse shear stiffness of three-dimensional truss-like core sandwich beam using a simplified two-dimensional unit … …American Journal of Applied Sciences, Vol. 9, Issue 2 · 26 Dec 2011 · 7,176 accessesView PDFCite
Case ReportOpen accessIn the keywordsSimulation of Stone Column Ground Improvement (Comparison between Axisymmetric and Plane Strain)Maryam Gaber, Anuar Kasa, Norinah Abdul-Rahman, Jamal AlsharefMost of the numerical studies on stone columns are based on the unit cell concept. However, the impact of interactions between adjacent columns and between the columns and the surrounding soil has not been investigated thoroughly. In this study, the finite element software, PLAXIS-2D-V8.2, was used to simulate a stone column as a unit cell and as a plane strain … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 1 · 16 Jan 2018 · 8,152 accessesView PDFCite
Research ArticleOpen accessIn the keywordsA Reduced Finite Element Model for Analyzing the Transverse Shear Stiffness of Truss-Like Core Sandwich BeamSuphattharachai Chomphan, Manit LeekitwattanaProblem statement: In structural analysis using finite element software, a number of finite element equations affect the speed of calculation time. A reduced finite element model should be used for analyzing structural responses to reduce the calculation time. Approach: This study presents the analysis of transverse shear stiffness of truss-like core sandwich beam using the reduced finite element model based … …Journal of Computer Science, Vol. 7, Issue 10 · 4 Aug 2011 · 6,589 accessesView PDFCite
Research ArticleOpen accessIn the keywordsWeighted Centroid Correction Localization in Cellular SystemsRong-Zheng Li, Xin-Long Luo, Jia-Ru LinProblem statement: There is a large demand for wireless Location-Based Service (LBS) and it is provided by many wireless cellular systems. In process of positioning a Mobile Station (MS), the computing speed is as important as the positioning accuracy and the algorithm should also be resistant to environmental influences. Approach: A new positioning method based on Weighted Centroid Correction Localization … …American Journal of Engineering and Applied Sciences, Vol. 4, Issue 1 · 27 Jan 2011 · 8,974 accessesView PDFCite
Research ArticleOpen accessIn the abstractBrain Tumor Segmentation and Classification Using HardNet Transformer With Gated Recurrent Unit ModelSaida D, Srinivas Adepu, Thade Lakshmi Devi et al.The uncontrolled growth of brain tumor cells presents a severe health risk, making early diagnosis and accurate classification essential for improving treatment outcomes. However, the existing approaches used for segmentation fail to delineate the tumor regions accurately due to a lack of global contextual information of brain tumors, resulting in poor classification performance. To overcome this limitation, this research proposes … …Journal of Computer Science, Vol. 22, Issue 9 · 26 Sep 2026 · 630 accessesView PDFCite
Research ArticleOpen accessIn the abstractFermentation Conditions of Lactobacilli for the Production of Lactose-Free Starter CultureMadina K. Imanbayeva, Zhaksylyk K. Masalimov et al.This research aims to determine the fermentation conditions and viability in a medium simulating the gastrointestinal tract and to examine the antagonistic potential of Lactobacillus acidophilus (Lb. acidophilus) and Lactobacillus rhamnosus (Lb. rhamnosus) in producing a lactose-free starter. Our study examined Lactic Acid Bacteria (LAB). The sources of Lb. acidophilus strains are camel milk (shubat), Lb. rhamnosus mare milk (koumiss), … …OnLine Journal of Biological Sciences, Vol. 24, Issue 2 · 7 Feb 2024 · 4,746 accessesView PDFCite
Research ArticleOpen accessIn the abstract3D Printing of Porous Scaffolds for Medical ApplicationsAblah Aljohani, Salil DesaiCustom engineered scaffolds that mimic the physiology of native tissue is an emerging need for successful regenerative medicine. One of the key challenges in current manufacturing methods is the lack of controlled porosity throughout the scaffold structure. In this research, our group explores the fabrication of tissue engineering scaffolds using 3D printing technology. The fused deposition modeling method was utilized … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 3 · 19 Jun 2018 · 8,508 accessesView PDFCite
