Quadrature mirror filter bank design based on hybrid bee colony technique

open access: yesAutomatika, 2021
This paper proposed a modified evolutionary technique formed by the hybridization of the bee colony technique and Nelder–Mead Simplex search technique to optimize the coefficients of Quadrature Mirror Filter (QMF). The performance of QMF can be evaluated

Comparison of Maximum Likelihood and some Bayes Estimators for Maxwell Distribution based on Non-informative Priors

open access: yesمجلة بغداد للعلوم, 2013
In this paper, Bayes estimators of the parameter of Maxwell distribution have been derived along with maximum likelihood estimator. The non-informative priors; Jeffreys and the extension of Jeffreys prior information has been considered under two ...

Existence and uniqueness of the modified error function [PDF]

open access: yes, 2023
This article is devoted to the proof of the existence and uniqueness of the modified error function introduced in Cho and Sunderland (1974). This function is defined as the solution to a nonlinear second order differential problem depending on a real ...

An application of modified sigmoid function to a class of $q-$ starlike and $q-$ convex analytic error functions

open access: yesTurkish Journal of Mathematics, 2022
Summary: In this study, in the open unit disc \(\Lambda\), by applying the \(q\)-derivative operator and the fractional \(q\)-derivative operator and by using the principle of subordination between analytic functions, we introduce some new interesting subclasses of \(q\)-starlike and \(q\)-convex analytic functions associated with error functions and ...

The Modified Trapezoidal Rule for Computing Hypersingular Integral on Interval

open access: yesJournal of Applied Mathematics, 2013
The modified trapezoidal rule for the computation of hypersingular integrals in boundary element methods is discussed. When the special function of the error functional equals zero, the convergence rate is one order higher than the general case.

Improved active disturbance rejection speed control for autonomous driving of high-speed train based on feedforward compensation

open access: yesScience Progress, 2023
Due to the complex and changeable train operation environment and the unstable and time-varying parameters, accurate modeling is limited. Therefore, a modified active disturbance rejection control algorithm based on feedforward compensation (FC-MADRC) is

Statistical Inference for the Heteroscedastic Partially Linear Varying-Coefficient Errors-in-Variables Model with Missing Censoring Indicators

open access: yesDiscrete Dynamics in Nature and Society, 2021
In this paper, we focus on heteroscedastic partially linear varying-coefficient errors-in-variables models under right-censored data with censoring indicators missing at random.

An extensive mathematical approach for wind speed evaluation using inverse Weibull distribution

open access: yesAlexandria Engineering Journal, 2023
Wind velocity and potential are frequently estimated using probability density functions (PDFs) such as the Inverse Weibull and Rayleigh. Determining whether they are suitable for modelling observed distributions is crucial.
