this article is devoted to study of the autoconvolution equations and generalized mittag-leffler functions. these types of equations are given in terms of the laplace transform convolution of a function with itself. we state new classes of the autoconvolution equations of the first kind and show that the generalized mittag-leffler functions are solutions of these types of equations. in view of ...
In the present study, the boundary value problems in generalized thermodiffusive elastic medium has been investigated as a result of inclined load. The inclined load is assumed to be a linear combination of normal load and tangential load. Laplace transform with respect to time variable and Fourier transform with respect to space variable are applied to solve the problem. As an application of t...
هدف در این پایان نامه پردازش و تحلیل سیگنال ها با استفاده از آنالیز فوریه و موجگ ها و همچنین یافتن ارتباط بین موجک ها و علم آمار است. در ابتدا تبدیل فوریه و ویژگی های آن بیان گردیده سپس موجک ها و تبدیلات آن ها معرفی و ایده های اصلی نهفته در آن ها توسط موجک های هار توصیف شده اند. دراین پایان نامه الگوریتم تجیه و بازسازی ها جهت پردازش سیگنال ها توضیح داده می شود ودر انتها کاربرد موجک ها در علم آم...
Conventional Fourier analysis has many schemes for different types of signals. They are Fourier transform (FT), Fourier series (FS), discrete-time Fourier transform (DTFT), and discrete Fourier transform (DFT). The goal of this correspondence is to develop two absent schemes of fractional Fourier analysis methods. The proposed methods are fractional Fourier series (FRFS) and discrete-time fract...
We report on a calculation of the chiral odd generalized parton distributions (GPDs) for non-zero skewness ζ in transverse and longitudinal position spaces by taking Fourier transform with respect to the transverse and longitudinal momentum transfer respectively using overlaps of light-front wave functions (LFWFs).
A new mathematical model of time fractional order heat equation and fractional order boundary condition have been constructed in the context of the generalized theory of thermo piezoelasticity. The governing equations have been applied to a semi infinite piezoelectric slab. The Laplace transform technique is used to remove the time-dependent terms in the governing differential equations and the...
We report a novel method to generate arbitrary optical focus arrays (OFAs). Our approach rapidly produces computer-generated holograms (CGHs) precisely control the positions and intensities of foci. This is achieved by replacing fast Fourier transform (FFT) operation in conventional iterative Fourier-transform algorithm (IFTA) with linear algebra one, identifying/removing zero elements from mat...
