Rotating disks with nonzero radial pressure and finite radius are studied.The models are based in the Taub-NUT metric and cons-tructed using the well-known "displace, cut and reflect" method.We find that the disks are made of perfect fluids with constant energy density Other Computer Adaptors and pressure.The energy density is negative, but the eff
Fatigue Behavior of Super Duplex Stainless Steel Exposed in Natural Seawater Under Cathodic Protection
Under operating conditions, alternated loading and fatigue are encountered, controlling the durability and safety of components and structures made of super duplex stainless steel (SDSS).In particular, the use of a Other Computer Adaptors cathodic protection (CP) system to protect the structure against corrosion can induce hydrogen charging of the
Optimization of Nano-Process Deposition Parameters Based on Gravitational Search Algorithm
This research is focusing on the radio frequency (RF) magnetron sputtering process, a physical vapor deposition technique which is widely used in thin film production.This process requires the optimized combination of deposition parameters in order to obtain the desirable thin film.The conventional method in the optimization of the deposition param
