In this paper, the problem under consideration is multiobjective non-linear fractional programming problem involving semilocally convex and related functions. We have discussed the interrelation between the solution sets involving properly efficient solutions of multiobjective fractional programming and corresponding scalar fractional programming problem. Necessary and sufficient optimality...

Abstract Single-phase brushless DC (BLDC) drives are a cost-effective alternative for three-phase sub-fractional horsepower in automotive auxiliary applications. Inherent features of single-phase permanent magnet machines, such as high cogging torque and ripple, can, however, make them more audible than their counterparts. As some these close to the passengers, where even small amount noise can...

In this article, we introduce the fractional differential systems in the sense of the Weber fractional derivatives and study the asymptotic stability of these systems. We present the stability regions and then compare the stability regions of fractional differential systems with the Riemann-Liouville and Weber fractional derivatives.

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 ...

1. It has been proposed that the enhanced erythrocyte Na+/Li+ countertransport observed in many patients with essential hypertension could be a marker of abnormal renal proximal tubular function. We thus investigated the relationship of blood pressure and Na+/Li+ countertransport to an index of proximal tubular function such as renal Li+ clearance. 2. The study was carried out in a sample of 29...

We study a general class of Euler equations driven by a forcing with a commutator structure of the form [L,u](ρ) = L(ρu)−L(ρ)u, where u is the velocity field and L is the “action” which belongs to a rather general class of translation invariant operators. Such systems arise, for example, as the hydrodynamic description of velocity alignment, where action involves convolutions with bounded, posi...

The land cover classes developed under the coordination of the International Geosphere-Biosphere Programme Data and Information System (IGBP-DIS) have been analyzed for a study area that includes the Conterminous United States and portions of Mexico and Canada. The 1-km resolution data have been analyzed to produce a gridded data set that includes within each 20-km grid cell: 1) the three most ...

fractional calculus has been used to model the physical and engineering processes that have found to be best described by fractional differential equations. for that reason, we need a reliable and efficient technique for the solution of fractional differential equations. the aim of this paper is to present an analytical approximation solution for linear and nonlinear multi-order fractional diff...

electroconvulsive therapy (ect) is an efficient treatment for several neuropsychiatric disorders however a large number of patients develop memory impairment after ect. different studies both on animals and human suggest that vasopressin has positive effects on memory and improves cognitive functions. in this randomized, double-blind controlled clinical trial, 50 patients with psychiatric disor...
