Friction Stir Welding (FSW) is a recently-developed technique where metals are joined together through mechanical stirring. FSW, often performed by robotic welders, is being used in an increasing number of industries such as aerospace, maritime and transportation. FSW has proven to be very effective and has replaced fusion welding and riveting in a number of manufacturing processes. In order to...

A power efficient gain adjustment technique is described to realize programmable gain current mirror. The dissipation power changes over the wide gain range of structure are almost negligible. This property is in fact very interesting from power management perspective, especially in analog designs. The simple structure and constant frequency bandwidth are other ever-interesting merits of propos...

This paper presents a two-stage low-noise ultra-wideband amplifier to obtain high and smooth gain in 180nm CMOS Technology. The proposed structure has two common source stages with inductive feedback. First stage is designed about 3GHz frequency and second stage is designed about 8GHz. In simulation, symmetric inductors of TSMC 0.18um CMOS technology in ADS software is used.Simulations results ...

Power gating technique reduces leakage power in the circuit. However, power gating leads to large voltage fluctuation on the power rail during power gating mode to active mode due to the package inductance in the Printed Circuit Board. This voltage fluctuation may cause unwanted transitions in neighboring circuits. In this work, a power gating architecture is developed for minimizing power in a...

fuel cells belong to an avant-garde technology family for a wide variety of applications including micro-power, transportation power, stationary power for buildings and other distributed generation applications. the first objective of this contribution is to find a suitable reduced model of a solid oxide fuel cell (sofc). the derived reduced model is then used to design a state estimator. in th...

iran-france relations have gone through many ups and downs in the last three decades. yet, during the last few years and especially during the presidency of sarkozy, an unforeseen coldness dominated the relations between the two countries. it seems that recent events in the area and iran’s nuclear power profile accompanied by changes taken place especially in france’s approach to iran. this pap...
