IEEE 802.11s wireless LAN mesh network technology is the next step in the evolution of wireless architecture. A WLAN mesh network consists of WLAN devices with relay functions that communicate directly. In this type of networks, path selection is based on two protocols: HWMP and RA-OLSR. This paper presents a detailed study of the performance of the proposed path selection algorithms for IEEE 8...
Topology optimization is a powerful digital engineering tool for the development of lightweight products. Nevertheless, transition obtained design proposals into manufacturable parts still challenging task. In this article, freeware framework shown, which uses hybrid topology algorithm stiffness and strength combined with manufacturing constraints based on finite spheres two-step smoothing to p...
در این پایان نامه آنتن های موجبری شکافدار منطبق بر مدارات مجتمع (siw antenna) و همچنین کاربرد اصلی آن به عنوان یک آنتن آرایه ای را مورد بررسی قرار گرفت. آنتن موجبری شکافدار استاندارد بر اساس روش جدید (optimized-classic) طراحی می گردد. این روش نه تنها اثرات تزویج از شکاف های همسایه را مورد بررسی قرار می دهد بلکه مودهای مرتبه بالاتری که از برخورد موج ورودی به شکاف ها حاصل می شود را نیز در نظر می ...
in this thesis,spin dependend transport and electron transport through of ng/sg(graphene/ superconductor graphen) are studied in the junction of ng/fgt/sg. due to andreev reflection conductance increases in the presence of superconductor graphene.also, by applying a voltage gate on a superconductor, fermi level shifts and the conductance is independent of ferromagnatic substrate. also, the cond...
this paper presents the method of reducing torque ripple of brushless dc (bldc) motor. the commutation torque ripple is reduced by control of the dc link voltage during the commutation time. the magnitude of voltage and commutation time is estimated by a neural network and optimized with an optimization method named particle swarm optimization (pso) algorithm analysis. the goal of optimization ...
