In this paper, based on certain variable transformation, we apply the known (G’/G) method to seek exact solutions for three fractional partial differential equations: the space fractional (2+1)-dimensional breaking soliton equations, the space-time fractional Fokas equation, and the spacetime fractional Kaup-Kupershmidt equation. The fractional derivative is defined in the sense of modified Rie...
Abstract Particle swarm optimization algorithm (PSO) is suggested to discover fractional order PID (FOPID) controller optimal variables for a better performance of induction motor. This PSO designed handle multiple issues, due its ease application. A Closed Loop Quadratic Boost Converter Multilevel Inverter Fed Induction Motor (QBCMLIIM) system simulated earn reduced switching losses and THD by...
The Linear Fractional Programming (LFP) problem that optimizes the ratio of two linear objective functions under constraints has a wide range application areas. Based on traditional definition continuity, we developed an exact iterative algorithm does not depend big-M coefficients. Removing nonlinearity in fractional function by converting into form, equivalent linear-iterative is obtained and ...
Cisplatin is a major anti-neoplastic agent which nephrotoxicity is its main side effect and limits its usage in cancer chemotherapy. Reactive oxygen species (ROS) are highly responsible for cisplatin induced nephropathy, so we determined the effects of oral administration of ethanolic olive leaf extract (OLE) as a plant antioxidant on nephrotoxicity of this drug. Material and methods: 21 adult...
Directional overcurrent relays (DOCRs) are widely used to protect power systems. For optimal coordination of DOCRs, several techniques have been proposed to solve this problem. A common way of optimal coordination of DOCRs is using evolutionary algorithms such as genetic algorithm (GA). In this paper, a novel strategy for DOCRs coordination is proposed. In the proposed strategy, a new objective...
in this paper, we prove the existence and uniqueness results to the random fractional functional differential equations under assumptions more general than the lipschitz type condition. moreover, the distance between exact solution and appropriate solution, and the existence extremal solution of the problem is also considered.
We prove duality between the left and right fractional derivatives, independently on the type of fractional operator. Main result asserts that the right derivative of a function is the dual of the left derivative of the dual function or, equivalently, the left derivative of a function is the dual of the right derivative of the dual function. Such duality between left and right fractional operat...
