Research ArticleOpen accessIn the abstractEffects of Noises on Fujisaki’s Model of Fundamental Frequency Contours for Thai DialectsSuphattharachai Chomphan, Chutarat ChompunthProblem statement: Modeling of fundamental frequency (F0) contour plays an important role on the natural speech processing, since F0 is an important speech feature defining the human speech prosody. In Thai, there are four main dialects spoken by Thai people residing in four core region including central, north, northeast and south regions. Environmental noises are also plays an important role … …American Journal of Applied Sciences, Vol. 9, Issue 10 · 25 Aug 2012 · 6,984 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Robust Recognition System for Pecan Weevil using Artificial Neural NetworksSaleh Mufleh Al-SaqerProblem statement: Pecan Weevil is a widely found pest among pecan trees and these pests are known to cause significant damage to the pecan trees resulting in enormous annual losses to pecan growers. Traditional identification techniques for pecan weevil include traps with pheromones to detect the infestation of these pests. However, these traditional methods require expensive labor hours to set-up … …American Journal of Applied Sciences, Vol. 9, Issue 9 · 14 Jul 2012 · 6,836 accessesView PDFCite
Research ArticleOpen accessIn the abstractTotal Petroleum Hydrocarbons By Gas Chromatography in Colombian Waters and SoilsC.. González, S. Roa, A. Suspes et al.Total Petroleum Hydrocarbons (TPHs) were required by the Colombian Environmental Authorities. However, the great diversity of hydrocarbon sources, in addition to the variety of available techniques and analytical methods had created confusion among the users of the data in regards to the appropriate methodologies. This study presents the results obtained in the method validation for the determination of TPHs in … …American Journal of Environmental Sciences, Vol. 8, Issue 4 · 20 Jun 2012 · 9,218 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Quasi Delay Insensitive Reduced Stack Pre-Charged Half Buffer based High Speed Adder using pipeline templates for Asynchronous CircuitsD. Jayanthi, M. RajaramProblem statement: Recent research in asynchronous design technique is making asynchronous circuits an increasingly practical alternative. These challenges include the increasing pressure for low power, the growing challenges of predicting the increasing impact of wire load and delay and the performance penalty associated with supporting communication between different clock domains Asynchronous is binary signals, but there is no common or … …Journal of Computer Science, Vol. 8, Issue 7 · 7 Jun 2012 · 7,084 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Wireless Sensor Node Supporting Various Powers Supply and Communication MethodsStefan Gruber, Hannes Reinisch, Hartwig Unterassinger et al.Problem statement: This study presents a wireless sensor node dedicated for in-tire pressure and temperature monitoring. Additional features set it apart from the many different systems available on the highly competitive market. State-of-the-art implementations are mounted on the rim of a tire. Here the sensor node will be mounted on the inner liner of the tire. By moving the sensor … …American Journal of Engineering and Applied Sciences, Vol. 4, Issue 4 · 12 Jan 2012 · 8,035 accessesView PDFCite
Research ArticleOpen accessIn the abstractA New Cooperative Algorithm Based on PSO and K-Means for Data ClusteringMehdi Neshat, Shima Farshchian Yazdi, Daneyal Yazdani, Mehdi SargolzaeiProblem statement: Data clustering has been applied in multiple fields such as machine learning, data mining, wireless sensor networks and pattern recognition. One of the most famous clustering approaches is K-means which effectively has been used in many clustering problems, but this algorithm has some drawbacks such as local optimal convergence and sensitivity to initial points. Approach: Particle Swarm Optimization … …Journal of Computer Science, Vol. 8, Issue 2 · 19 Nov 2011 · 7,975 accessesView PDFCite
