Research ArticleOpen accessEvery word in the titleMeasuring Drivers’ Effect in a Cost Model by Means of Analysis of VarianceMaria Elena NenniIn this study the author goes through with the analysis of a cost model developed for Integrated Logistic Support (ILS) activities. By means of ANOVA the evaluation of impact and interaction among cost drivers is done. The predominant importance of organizational factors compared to technical ones is definitely demonstrated. Moreover the paper provides researcher and practitioners with useful information to … …American Journal of Applied Sciences, Vol. 10, Issue 12 · 24 Oct 2013 · 6,448 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleSimplified Modeling, Analysis and Simulation of Permanent Magnet Brushless Direct Current Motors for Sensorless OperationE. Kaliappan, C. ChellamuthuProblem statement: In this study, a simplified modeling and experimental analysis of Permanent Magnet Brushless DC (PMBLDC) motors for Sensorless operation using MATLAB/SIMULINK. This model provides a mechanism for monitoring and controlling the voltage, current, speed and torque response. Approach: BLDC motor is modeled as sub-blocks. The inverter and switching function are implemented as S-function builder block. The Sensorless scheme … …American Journal of Applied Sciences, Vol. 9, Issue 7 · 16 May 2012 · 7,643 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleAnalysis of Decision Trees in Context Clustering of Hidden Markov Model Based Thai Speech SynthesisSuphattharachai ChomphanProblem statement: In Thai speech synthesis using Hidden Markov model (HMM) based synthesis system, the tonal speech quality is degraded due to tone distortion. This major problem must be treated appropriately to preserve the tone characteristics of each syllable unit. Since tone brings about the intelligibility of the synthesized speech. It is needed to establish the tone questions and other … …Journal of Computer Science, Vol. 7, Issue 3 · 7 Mar 2011 · 6,844 accessesView PDFCite
Research ArticleOpen accessEvery word in the titlePrediction and Analysis of COVID-19 Cases using Regression Models: A Descriptive Case Study of IndiaIsmail KeshtaThe Coronavirus(SARS-CoV-2) is a respiratory illness that emerged in Wuhan, China, on December31, 2019, according to reports by the World Health Organization (WHO). Hospitalrecords in India indicate that COVID-19 hospitalizations in the second wave ofCOVID-19 more than doubled those in the first wave. Limited studies have beenconducted to establish the extent to which the second wave of COVID-19increased the infection … …Journal of Computer Science, Vol. 18, Issue 10 · 12 Oct 2022 · 6,156 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleAnalysis of Mechatronics Degree Evaluation ModelsJean Bosco Samon, Brice Landry Tekam GuessomA mechatronic system is an intelligent product that is usually very complex and deserves to be characterized. The complexity comes from the number of integration of functions in a single product. Mechatronizability, which is the ability of the degree of mechatronics of a system, is a remarkable characteristic for designers to decide the level of complexity at the design stage … …Journal of Mechatronics and Robotics, Vol. 6, Issue 1 · 31 Jul 2022 · 5,710 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleModeling and Performance Analysis of a Petroleum-Pipeline-Pressure-Boosting Station Powered by Two-Shaft GT EngineYousef S. H. Najjar, Mohammad Z. M. Yousef, Aad M. A. Al-MahgariThis study offers modeling and performance analysis of a pressure-boosting station for petroleum pipelines using a sustainable two-shaft GT engine to drive a three-stage centrifugal pump. The modeling is divided into three steps; matching the GT engine components at the maximum efficiency line, matching the pump performance with the requirements of the pipeline system to generate the pump load curve, … …Energy Research Journal, Vol. 12, Issue 1 · 18 Jan 2022 · 10,510 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleModeling and Analysis of MRR, EWR and Surface Roughness in EDM Milling through Response Surface MethodologyA.K.M. Asif Iqbal, Ahsan Ali KhanProblem statement: Electrical Discharge Machining (EDM) has grown over the last few decades from a novelty to a mainstream manufacturing process. Though, EDM process is very demanding but the mechanism of the process is complex and far from completely understood. It is difficult to establish a model that can accurately predict the performance by correlating the process parameters. The optimum … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 4 · 4 Nov 2010 · 9,606 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEvaluation of Rutting Depth in Flexible Pavements by Using Finite Element Analysis and Local Empirical ModelAlaa H. Abed, Adel A. Al-AzzawiThe objective of this research is to predict rut depth in local flexible pavements. Predication model in pavement performance is the process that used to estimate the parameter values which related to pavement structure, environmental condition and traffic loading. The different local empirical models have been used to calculate permanent deformation which include environmental and traffic conditions.

Research ArticleOpen accessEvery word in the titleBUSINESS LOGIC EVALUATION MODEL USING DEPENDENCY ANALYSIS APPROACH FOR SER-VICE INTEGRATIONM. Thirumaran, M. Jannani, P. Dhavachelvan et al.In order to extract and integrate the required business logics from the rapidly expanding business services accurately and efficiently, developers must fathom the entire service and must decide on the proper approach to merge them which is a complex and time-consuming task. So integrating the service logics automatically by scrutinizing the dependency relations existing on business rules, functions and parameters … …American Journal of Applied Sciences, Vol. 11, Issue 8 · 10 May 2014 · 6,510 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleA Drives and Control Integrated Time-Domain Dynamic Analysis and Modeling Approach Applied To Ultra-Precision Machine ToolsTianjian Li, Shijin Chen, Haijun Zhang, Kai ChengProblem statement: Machines dynamic performance depends not only upon the mechanical structure and components but also the drives and control system. However, the design of the machines is still at the nascent stage by working on an individual machine basis, hence lacks generic scientific approach and design guideline. Approach: Using computer models integrated drives and control system to predict the … …Current Research in Nanotechnology, Vol. 2, Issue 1 · 29 Jul 2011 · 8,088 accessesView PDFCite
