Research ArticleOpen accessIn the abstractAmphoteric Starch in Simultaneous Process Preparation with Box-Behnken Design for Optimal ConditionsSopa Cansee, Juntanee Uriyapongson, Commueng Watyotha et al.Cassava starch was chemically modified to produce an amphoteric starch. The amphoteric starch was prepared in a simultaneous process which was evaluated in relation to four factors: temperature (45-55 °C), 3-chloro-2-hydroxypropyltrimethylammonium chloride (CHPTAC, 4-12%) and sodium tripolyphosphate (STP, 2-8%) concentrations, and reaction time (2-6 h). The extent of amphoteric starch produced was determined by the degree of substitution (DS) of … …American Journal of Applied Sciences, Vol. 5, Issue 11 · 30 Nov 2008 · 7,527 accessesView PDFCite
Research ArticleOpen accessIn the abstractTraffic Signal Using Smart Agent SystemCheonshik Kim, You-Sik HongIn this research, we propose an electro-sensitive traffic light using the smart agent algorithm to reduce traffic congestion and traffic accidents. The multi-agent system approach can provide a new and preferable solution. The proposed method adaptively controls the cycle of traffic signals even though the traffic volume varies. Consequently, we reduce the car waiting time and start-up delay time using … …American Journal of Applied Sciences, Vol. 5, Issue 11 · 30 Nov 2008 · 6,958 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Multicollinearity on Power Rates of the Ordinary Least Squares EstimatorsO.O. Alabi, Kayode Ayinde, T.O. OlatayoInferences on the parameter estimates of Ordinary Least Square (OLS) estimator in regression model when regressors exhibit multicollinearity is a problem in that large standard errors of the regression coefficients which cause low t-statistic value often result into the acceptance of the null hypothesis. This paper, therefore, makes efforts to investigate the effect of multicollinearity on the power rates of … …Journal of Mathematics and Statistics, Vol. 4, Issue 2 · 30 Jun 2008 · 7,884 accessesView PDFCite
Research ArticleOpen accessIn the abstractUsing IRS Products to Recover 7ETM+ Defective ImagesMobasheri Mohammad Reza, Sadeghi Naeini AliOn May 31st, 2003, Landsat 7 faced an anomaly in the Scan Line Corrector (SLC) normal operation. This malfunctioning of SLC caused the individual scan lines alternately overlap each other and consequently produce large gaps at the edges of the image. Regarding the unique specification of ETM+ sensor on board of Landsat-7 satellite such as its spectral bands in the … …American Journal of Applied Sciences, Vol. 5, Issue 6 · 30 Jun 2008 · 6,967 accessesView PDFCite
Research ArticleOpen accessIn the abstractHow Greece and Ireland Have Been Positioned in the World Developments Since 1945: A French Regulation ApproachLavrentios VasiliadisThis research analyses how Greece and Ireland have been positioned in the world development since 1945 by using the French Regulation Approach. In particular, this analysis describes three broad periods, notably the Fordist, post-Fordist and the New Economy ones. In each period, apart from the general approach that concerns the world economy transformation, the specific transformations of the economies of … …Journal of Social Sciences, Vol. 4, Issue 1 · 31 Mar 2008 · 7,362 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Study of Thermal Contact using Nonlinear System Identification ModelsM.H. Shojaeefard, K. Goudarzi, A.R. Noorpoor, M. FazelpourOne interesting application of system identification method is to identify and control the heat transfer from the exhaust valve to the seat to keep away the valve from being damaged. In this study, two co-axial cylindrical specimens are used as exhaust valve and its seat. Using the measured temperatures at different locations of the specimens and with a semi-analytical method, … …American Journal of Engineering and Applied Sciences, Vol. 1, Issue 1 · 31 Mar 2008 · 7,533 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Assessment of Compressive Size Effect of Plane Concrete Using Combination of Micro-Plane Damage Based Model and 3D Finite Elements ApproachM. Labibzadeh, S. A. Sadrnejad, M. NaisipourIn recent years, the material behavior dependence of laboratory concrete specimens built with the same concrete mixture under the same load conditions to their geometrical sizes is well established. This phenomenon which is observed not only in concrete but also in most quasi-brittle materials such as rock, ceramic or composite materials is now called as size effect. Many of the … …American Journal of Applied Sciences, Vol. 5, Issue 2 · 28 Feb 2008 · 7,007 accessesView PDFCite
Research ArticleOpen accessIn the abstractAnalysis Heat Flow Between Seat and Valve of ICEM.H. Shojaefard, A.R. Noorpoor, M. Ghaffarpour, F. MohammadiAn interesting application of system identification method is to investigate the heat transfer from the exhaust valve, especially the valve burning at high temperatures. This study consists of experimental and analytical works. For the experiment, two co-axial rods were used to transfer heat constantly at their contact surfaces. Using the measured temperatures at different locations of the rods and the … …American Journal of Applied Sciences, Vol. 4, Issue 9 · 30 Sep 2007 · 7,208 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Integrated Quantitative Assessment Model For Usability EngineeringHaidar S. Jabbar, T. V. Gopal, Sattar J. AboudMany different quantitative assessment models have been proposed to measure and report the usability of a general software product for various business and design purposes. However, there are several problems coupled with existing models that consequently bias and affect the process and results of the usability assessment. Moreover, they do not aid their usage by analysts who are not experienced … …Journal of Computer Science, Vol. 3, Issue 5 · 31 May 2007 · 6,706 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Characterization of Al Bond Pad Surface Treatment in Electroless Nickel Immersion Gold (ENIG) DepositionM.K. Md Arshad, A. Jalar, I. Ahmad, G. OmarThis study reports a number of experiments that were designed to characterize aluminum bond pad surfaces prior to electroless nickel immersion gold (ENIG). In the ENIG process, aluminum bond pads need special treatment to achieve successful nickel deposition and provide reliable interconnection of under bump metallurgy in advanced packaging. During this treatment process, the aluminum pad was cleaned, activated and … …American Journal of Applied Sciences, Vol. 4, Issue 3 · 31 Mar 2007 · 7,728 accessesView PDFCite
