دراین پایان نامه اعمال شرط مرزی ورود وخروج به روشisphبا الگوریتم fractional step بررسی می شود و ایده ای ارائه می گردد که همه ی الزامات ورودی و خروجی جریان برای روش مبنا ذره ای sph در آن لحاظ می شود. ابتدا سعی می شود نحوه ی اعمال شرایط مرزی ورود/ خروج، برای جریان داخل یک لوله افقی توضیح داده شود ونتایج با حل تحلیلی صحت سنجی می شود. در ادامه از آن برای مدل کردن جریان بر روی پله وارون(backward-fac...
In this paper, the fractional partial differential equations are defined by modified Riemann-Liouville fractional derivative. With the help of fractional derivative and fractional complex transform, these equations can be converted into the nonlinear ordinary differential equations. By using solitay wave ansatz method, we find exact analytical solutions of the space-time fractional Zakharov Kuz...
the purpose of this paper is to study the fuzzy fractional differentialequations. we prove that fuzzy fractional differential equation isequivalent to the fuzzy integral equation and then using this equivalenceexistence and uniqueness result is establish. fuzzy derivative is considerin the goetschel-voxman sense and fractional derivative is consider in theriemann liouville sense. at the end, we...
using the riemann-liouville fractional differintegral operator, the lie theory is reformulated. the fractional poisson bracket over the fractional phase space as 3n state vector is defined to be the fractional lie derivative. its properties are outlined and proved. a theorem for the canonicity of the transformation using the exponential operator is proved. the conservation of its generator is p...
We study the zero frequency noise in an interacting quantum wire connected to leads, in the presence of an impurity. In the absence of quasiparticle decoherence the zerofrequency noise is that of a non-interacting wire. However, if the collective, fractionallycharged modes have a finite lifetime, we find that the zero-frequency noise may still exhibit signatures of charge fractionalization, suc...
in this paper, we apply the local fractional adomian decomposition and variational iteration methods to obtain the analytic approximate solutions of fredholm integral equations of the second kind within local fractional derivative operators. the iteration procedure is based on local fractional derivative. the obtained results reveal that the proposed methods are very efficient and simple tools ...
Let G be a graph of order p, and let a, b and n be nonnegative integers with b ≥ a ≥ 2, and let f be an integer-valued function defined on V (G) such that a ≤ f(x) ≤ b for each x ∈ V (G). A fractional f -factor is a function h that assigns to each edge of a graph G a number in [0,1], so that for each vertex x we have dG(x) = f(x), where d h G(x) = ∑ e3x h(e) (the sum is taken over all edges inc...
