Research ArticleOpen accessIn the abstractEffects of Higher Order Dispersion Terms in the Nonlinear Schrodinger EquationRobert Beech, Frederick OsmanThis study presents a concise graphical analysis of solitonic solutions to a nonlinear Schrodinger equation (NLSE). A sequence of code using the standard NDSolve function has been developed in Mathematica to investigate the acceptable accuracy of the NLSE in relatively small ranges of the dispersive parameter space. An operator splitting approach was used in the numerical solutions to expand the … …American Journal of Applied Sciences, Vol. 2, Issue 9 · 30 Sep 2005 · 6,493 accessesView PDFCite
Research ArticleOpen accessIn the abstractβ-Spline Estimation in a Semiparametric Regression Model with Nonlinear Time Series ErrorsJinhong You, Gemai Chen, Xian ZhouWe study the estimation problems for a partly linear regression model with a nonlinear time series error structure. The model consists of a parametric linear component for the regression coefficients and a nonparametric nonlinear component. The random errors are unobservable and modeled by a first-order Markov bilinear process. Based on a B-spline series approximation of the nonlinear component function, we … …American Journal of Applied Sciences, Vol. 2, Issue 9 · 30 Sep 2005 · 6,737 accessesView PDFCite
Research ArticleOpen accessIn the abstractAsymptotic Hyperstability of Dynamic Systems with Point DelaysM. De la SenIt is proved that a linear time-invariant system with internal point delays is asymptotically hyperstable independent of the delays if an associate delay-free system is asymptotically hyperstable and the delayed dynamics are sufficiently small. …American Journal of Applied Sciences, Vol. 2, Issue 9 · 30 Sep 2005 · 6,702 accessesView PDFCite
Research ArticleOpen accessIn the abstractOn the Stability of a Certain Class of Linear Time-Varying SystemsM. De la SenThis study firstly considers the exponential stability of unforced linear systems of slowly time-varying dynamics. Possible switchings of the system structure to unstable dynamics during certain finite time intervals are admitted. The maintenance of global exponential stability does not necessarily require at most a finite number of switchings in the dynamics while infinitely many switches can also lead to stability. … …American Journal of Applied Sciences, Vol. 2, Issue 8 · 31 Aug 2005 · 6,937 accessesView PDFCite
Research ArticleOpen accessIn the abstractElectrochemical Characteristics of Some Purpurins in Aqueous and Nonaqueous SolutionsFarouk A. Rashwan, Hossnia S. Mohran, Ahmed A. El-SamahyThe Electrochemical Impedance Technique (EIS) and the Cyclic Voltammetric method (CV) were used to investigate the behavior of purpurin (P), Anthrapurpurin (AP) and Benzopurpurin (BP) in aqueous and in N, N-dimethylformamide (DMF) media. In the CV experiments, both the radical and the dianion of these substances were assumed to form of limited stability due to chemical protonation. In case of … …American Journal of Applied Sciences, Vol. 2, Issue 7 · 31 Jul 2005 · 6,744 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Overview for Decomposition of Industry Energy ConsumptionChun-Chu LiuThis study is to overview several methodological related to the decomposition approach based on the energy consumption. Based on a comparison of the size of the residual term that the adaptive weighting Divisia and the simple average Divisia index method, is most robust, exhibiting the smallest residual term. A complete decomposition model also introduced here has solved a residual problem. …American Journal of Applied Sciences, Vol. 2, Issue 7 · 31 Jul 2005 · 6,713 accessesView PDFCite

Research ArticleOpen accessIn the abstractIntroducing Song Form Intelligence into Streaming AudioKevin CurranWhen receiving streaming media over a low bandwidth wireless connection, users can experience not only packet losses but also extended service interruptions. These dropouts can last for as long as 15 sec. During this time no packets are received and if not addressed, these dropped packets cause unacceptable interruptions in the audio stream. A long dropout of this kind may … …Journal of Computer Science, Vol. 1, Issue 2 · 30 Jun 2005 · 6,575 accessesView PDFCite
