Research ArticleOpen accessEvery word in the titleNumerical Simulation of a Turbulent Lean, Premixed Combustion with an Explicit Algebraic Stress ModelWilliam Vicente, Martín Salinas-Vázquez, Eliseo Martínez, Alejandro RodríguezA computational model is used in the present paper to study the influence of the turbulence modeling on the chemical species in a turbulent lean premixed flame. The simulated configuration is about a lean, premixed bluff-body-stabilized flame with a recirculation zone. To achieve the objectives, three different models were used for turbulence modeling as listed next: 1) standard k-ε, 2) … …Journal of Mathematics and Statistics, Vol. 1, Issue 2 · 30 Jun 2005 · 6,316 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleDifferSqueezeNet: A Leaner Defect Detection ModelJose Joao Manrique Franco, Marcelo RudekIn the industrial environment, the inherent limitations of manual inspection have caused the ascent of automated computer vision systems that aim to match or surpass human performance. In this context, the artificial intelligence field has been interested in defect detection with the creation of many machine learning techniques, focusing on Unsupervised and Semi-supervised learning methods. Since most of these methods … …Journal of Computer Science, Vol. 21, Issue 3 · 4 Feb 2025 · 5,727 accessesView PDFCite
Research ArticleOpen accessIn the keywordsSmart Manufacturing in Mining. Adopting Machine Learning to Improve a Copper Milling ProcessFederico Walas Mateo, Andrés Redchuk, Julian Eloy TornilloNowadays industries like mining are focused in the need of improving processes towards net zero emissions and accomplishing with united nations' sustainable development goals. This article presents a case at a copper mine where an artificial intelligence solution is adopted to optimize industrial processes. The paper illustrates the way a software solution using a low code platform framework can democratize … …Journal of Mechatronics and Robotics, Vol. 7, Issue 1 · 15 Apr 2023 · 6,312 accessesView PDFCite
Research ArticleOpen accessIn the keywordsA NOVEL OPTIMIZATION MODEL FOR SIMULTANEOUS COST-RISK REDUCTION IN MULTI-SUPPLIERS JUST-IN-TIME SYSTEMSFaraj El Dabee, Romeo Marian, Yousef AmerIn today’s competitive global markets, Just-in-Time (JIT) is one of the main lean manufacturing approaches. It is used in organizations to improve performance and reduce costs and as a strategic core capability to ensure their market position. However, using JIT tightly couples various functions of the Supply Chain and increases the risk of propagating disruptions through the entire system. This … …Journal of Computer Science, Vol. 9, Issue 12 · 25 Nov 2013 · 7,610 accessesView PDFCite
Research ArticleOpen accessIn the keywordsThe Use of E100 to Fuel a Used 4-Stroke MotorcycleT. SuthisripokProblem statement: Though ethanol and gasohol are proved to be used as alternative fuels in vehicles, 4-stoke motorcycles used nationwide mainly consumed gasoline 91/95. Approach: The motorcycle tested, the used Honda Wave125 model, was properly tuned at the rich relative air-fuel ratio (λ) 0.85, which theoretically gave the maximum power output. For the use of E100, the engine required richer … …American Journal of Applied Sciences, Vol. 9, Issue 5 · 23 Feb 2012 · 9,474 accessesView PDFCite
Research ArticleOpen accessIn the author namesUnderstanding the Epidemiology of Trypanosoma Evansi Infection in Dogs (Canis lupus familiaris) from Urban Areas of ColombiaJeiczon Elim Jaimes-Dueñez, Ángela Patricia Jiménez-Leaño, Daniela Montenegro-Ayala, Maria Esteban-MendozaTrypanosomaevansi is a protozoan parasite that is the causative agent of the animal disease known as "surra", which affects a wide variety of wild and domestic mammals including humans. This study aimed to evaluate the molecular point prevalence and clinic-epidemiological traits of T. evansi infection in dogs from municipalities of the Metropolitan Area of Bucaramanga (MAB), Santander, Colombia. From 2019 … …American Journal of Animal and Veterinary Sciences, Vol. 17, Issue 2 · 1 Jul 2022 · 5,937 accessesView PDFCite
Research ArticleOpen accessIn the author namesA User-Driven Association Rule Mining Based on Templates for Multi-Relational DataCarlos Roberto Valêncio, Guilherme Henrique Morais, Márcio Zamboti Fortes et al.Data mining algorithms to find association rules are an important tool to extract knowledge from databases. However, these algorithms produce an enormous amount of rules, many of which could be redundant or irrelevant for a specific decision-making process. Also, the use of previous knowledge and hypothesis are not considered by these algorithms. On the other hand, most existing data mining … …Journal of Computer Science, Vol. 14, Issue 11 · 8 Nov 2018 · 7,442 accessesView PDFCite
Research ArticleOpen accessIn the author namesVERBO: Voice Emotion Recognition dataBase in Portuguese LanguageJosé R. Torres Neto, Geraldo P.R. Filho, Leandro Y. Mano, Jó UeyamaThe recognition of human emotional traits based on Affective Computing is being carried out by computational systems that are able to interpret and react intelligently to the context of the user. Speech Emotion Recognition systems are capable of transforming speech signal data into information related to the feelings of individuals in specific situations. However, the emotional expression of a human … …Journal of Computer Science, Vol. 14, Issue 11 · 2 Nov 2018 · 9,453 accessesView PDFCite
Research ArticleOpen accessIn the author namesExploring Mesh Generation and Quality Enhancement with Open Source CodesLeandro Alves Neves, José Márcio Machado, Julio Cesar Momente et al.The finite element method is a very reliable and precise technique for solving partial differential equations in three-dimensional domains, with relevant applications in several areas. However, 3D simulations by FEM require computer programs for solid modeling and automatic mesh generation and there are few examples of open source codes available and dedicated to these tasks. Unfortunately, these open source codes … …Journal of Computer Science, Vol. 14, Issue 7 · 19 Jul 2018 · 8,357 accessesView PDFCite
Research ArticleOpen accessIn the author namesMultidrug-Resistant Bacterial Pathogens Assessment in Canine Ophthalmic InfectionsRicardo Antonio Pilegi Sfaciotte, Lincoln Garcia Coronel, Alessandra Snak et al.The objective of this study was to identify the main microorganisms associated with ophthalmic infections and determine the resistance profile of these isolates against antimicrobial drugs. 26 bacterial isolates from 18 canine ophthalmic infections were submited to the phenotypic resistance profile for 36 drugs of 12 classes of antimicrobials, research of multidrug-resistant strains with importance in public health and detection … …American Journal of Animal and Veterinary Sciences, Vol. 13, Issue 1 · 2 Jan 2018 · 7,275 accessesView PDFCite
