in order to the enhancement of the quality of speech corrupted by additive noise, a speech enhancement method has been put forward based on the combination of spectral subtraction and binary masking. spectral subtraction is a powerful method for removing noise from speech and binary masking provides essential elements to be used in monaural speech segregation. in the proposed combined method, f...

In this paper, an efficient numerical scheme based on uniform Haar wavelets is used to solve the non-planar Burgers equation. The quasilinearization technique is used to conveniently handle the nonlinear terms in the non-planar Burgers equation. The basic idea of Haar wavelet collocation method is to convert the partial differential equation into a system of algebraic equations that involves a ...

The main objective of this study is to present new method on the basis of genetic algorithms for attenuation relationship determination of horizontal peak ground acceleration and spectral acceleration. The proposed method employs the optimization capabilities of genetic algorithm to determine the coefficients of attenuation relationships of peak ground and spectral accelerations. This method ha...

Abstract The improvement in thermal performance of fluid and the control energy loss are equitably significant. Therefore, purpose this study is to analyze entropy generation, stagnation point flow, characteristics non-Newtonian third-grade modified hybrid nanofluid generated by a stretchable/shrinkable Riga plate porous medium with varying flow viscosity. In analysis, modification considered u...

Advances in automatic control theory may be seen to have two main objectives the synthesis of improved controllers for a given plant and the extension of the range of plants considered for control. Optimal control theory and its application to linear stems is an example of the former, whilst advances in the latter have been largely concerned with describing-function and quasilinearization techn...

In this paper, a new spectral-iterative method is employed to give approximate solutions of fractional logistic differential equation. This approach is based on combination of two different methods, i.e. the iterative method cite{35} and the spectral method. The method reduces the differential equation to systems of linear algebraic equations and then the resulting systems are solved by a numer...
