Research ArticleOpen accessEvery word in the titleEvaluation of Gaussian Plume Model against CFD Simulations through the Estimation of CO and NO Concentrations in an Urban AreaMahmoud BadyDispersion of air pollutants, Carbon monoxide (CO) and Nitrogen oxide (NO), due to three point sources and a high-density traffic road in an urban area located near the center of Tokyo, Japan was studied using two different approaches. The first is an analytical approach using Gaussian Plume Model (GPM) while the second is a numerical approach using Computational Fluid Dynamics … …American Journal of Environmental Sciences, Vol. 13, Issue 2 · 12 Apr 2017 · 7,907 accessesView PDFCite
Research ArticleOpen accessEvery word in the titlePerformance Evaluation of Channel Propagation Models and Developed Model for Mobile CommunicationYahia ZakariaPropagation models represent a solidifying of mathematical equations and algorithms that are used for radio signal propagation prediction in specific regions. In this research different propagation models are analyzed and compared. These propagation models have been proposed at the operating frequency of 3.8 GHz for different transmitter antenna heights in all types of terrain. These propagation models depend on location, … …American Journal of Applied Sciences, Vol. 14, Issue 2 · 25 Feb 2017 · 8,409 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEvaluation Model of MechatronizabilityJean Bosco Samon, Brice Landry Tekam GuessomCompetitiveness pushes companies to redefine their production units to offer multifunctional products. The integration of several functions requires the marriage of several disciplines of mechatronics that it is necessary to measure its dimension of integration. Because the problem of the designers or the professionals of the mechatronics is the one to know the level or the degree of the mechatronics … …Journal of Mechatronics and Robotics, Vol. 6, Issue 1 · 4 Aug 2022 · 5,545 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleSkin Color Detection Model Using Neural Networks and its Performance EvaluationK. K. Bhoyar, O. G. KakdeProblem statement: Skin color detection is used as a preliminary step in numerous computer vision applications like face detection, nudity recognition, hand gesture detection and person identification. In this study we present a pixel based skin color classification approach, for detecting skin pixels and non skin pixels in color images, using a novel neural network symmetric classifier. The neural classifiers … …Journal of Computer Science, Vol. 6, Issue 9 · 30 Sep 2010 · 8,058 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleUsing the Analytic Hierarchy Process to Establish a Tour Guide Selection and Evaluation ModelHan-Chen Huang, Su-Ling Wu, I-Ying Chang, Pei-Ling LiuThis study aims to examine the criteria for the selection of tour guides, in order to help travel agencies in Taiwan selecting suitable tour guides with a more objective and consistent approach. A tour guide is the life and soul of an organized tour, as well as an important key for the success of the tour.
