We generalize existing Jacobi–Gauss–Lobatto collocation methods for variable-order fractional differential equations using a singular approximation basis in terms of weighted Jacobi polynomials of the form (1 ± x)μP a,b j (x), where μ > −1. In order to derive the differentiation matrices of the variable-order fractional derivatives, we develop a three-term recurrence relation for both integrals...
In the fractional ownership model, the partial owner of an aircraft is entitled to certain flight hours per year, and the management company is responsible for all the operational considerations of the aircraft and for making an aircraft available to the owner at the requested time and place. In the recent years although the industry as a whole has experienced significant growth, most of the ma...
in this manuscript a new method is introduced for solving fractional differential equations. the fractional derivative is described in the caputo sense. the main idea is to use fractional-order legendre wavelets and operational matrix of fractional-order integration. first the fractional-order legendre wavelets (flws) are presented. then a family of piecewise functions is proposed, based on whi...
پیشرفت اخیر در حسابان کسری (fractional calculus) منجر به معرفی کاربردهایی از حسابان کسری در تئوری کنترل شده است. یکی از کاربردهای اولیه حسابان کسری کنترل-کننده های مرتبه کسری (fractional order) می باشند که توانسته اند توجه قابل ملاحظه ای را در بررسی های آکادمیک و کاربردهای صنعتی به خود جلب کنند. در این پایان نامه از کنترل کننده های مرتبه کسری به عنوان کنترل کننده مکمل جبرانگر استاتیکی توان راکت...
هدف: این مطالعه به منظور بررسی میزان اثربخشی fractional co2 laser در درمان اسکار انجام شده است. روش مطالعه: این مطالعه به صورت یک clinical case series انجام شده است. حجم نمونه مورد بررسی شامل 81 بیمار مبتلا به اسکار بود که طی سال 1388 جهت درمان به کلینیک های درماتولوژی در سطح شهر تهران مراجعه نموده بودند.یافته ها: میانگین میزان پاسخ به درمان در هر جلسه لیزردرمانی 26/29 درصد بود. 20 نفر (7/24 د...
In this study, we obtained a system of eigenfunctions and eigenvalues for the mixed homogeneous Sturm-Liouville problem second-order differential equation containing fractional derivative operator. The differentiation operator was considered according to two definitions: Gerasimov-Caputo Riemann-Liouville-Visualizations eigenfunctions, biorthogonal system, distribution on real axis were present...
We aim to present some formulas for the Saigo hypergeometric fractional integral and differential operators involving the generalized Mathieu series Sμ(r), which are expressed in terms of the Hadamard product of the generalized Mathieu series Sμ(r) and the Fox–Wright function pΨq(z). Corresponding assertions for the classical Riemann–Liouville and Erdélyi–Kober fractional integral and different...
Based on recent studies by Guy Jumarie [1] which defines probability density of fractional order and fractional moments by using fractional calculus (fractional derivatives and fractional integration), this study expands the concept of probability density of fractional order by defining the fractional probability measure, which leads to a fractional probability theory parallel to the classical ...

in this paper an approximate analytical solution of the fractional zakharov-kuznetsov equations will be obtained with the help of the reduced differential transform method (rdtm). it is in-dicated that the solutions obtained by the rdtm are reliable and present an effective method for strongly nonlinear fractional partial differential equations.
