In this paper by using numerical evaluation the effect of balancing drupes of water hammer on tunnels lining is considered. In case of not arrangment of these reservoirs, the tunnel lining will be damaged of cyclic powers of water hammer. In this research, function of balancing reservoir of water hammer on cover of tunnels to the barriers’ turbine is simulated by numerical methods and Plaxis 3D...

PURPOSE OF REVIEW Publicly funded health care systems are increasingly confronted with fiscal and demographic challenges and face pressure to constrain resource use without impacting clinical outcomes. FINDINGS Clinicians routinely make decisions in the care of their patients that use finite health care resources. Aligning the goal of caring for their patients with ensuring that effective int...

Abstract The voltage balance of the series diodes is premise to ensure stable and reliable operation high uncontrolled rectifier valve. When traditional RC RCD balancing methods are applied valves in far-reaching offshore wind farms, complex changeable operating environment poses a challenge anti-interference effect snubber circuit. In this paper, an active adaptive control strategy with strong...

Low powered fully implantable cochlear implants (FICIs) untangle the aesthetic concerns and battery replacement problems of conventional implants. However, reported FICIs lack proper charge balancing require multiple external supplies to operate. In this work, a complete low power FICI interface circuit is designed that operates with single supply uses short-pulse-injection method for balancing...

This paper presents a grid connected photovoltaic system, which acts as both power generator and active power filter (APF), based on Flying Capacitor Multicell (FCM) converter. Increase in the number of output voltage levels, natural self-balancing of flying capacitors and dc link voltage and lower power rating of components are the main futures of FCM converter compared with conventional multi...
