Thermal oxidation of copper is a simple and scalable method to produce copper oxide nanowires. We report for the first time the formation of nanowires on copper powder during thermal oxidation and the resulting nanowire coverage that is dependent on initial particle size. Systematic thermogravimetric analysis (TGA) and in-situ x-ray diffraction (XRD) studies of thermal oxidation of particles of different...
Allowing the receiver in a multiple antenna wireless system to send a limited amount of channel state information (CSI) feedback is an effective way to enable channel adaptive signaling. This paper addresses the problem of controlling the feedback update period and feedback rate of limited feedback multiple antennas systems in temporally correlated channels. The challenge in our problem is how to...
While many preferred methods exist for protecting components against damage from ground fault currents on 480-V systems, few analyses (if any) have been made concerning the effects on components (molded-case breaker, overload relay, etc.) due to a failure or absence of a ground fault protective device to clear a ground fault. Unlike fuses, which by definition could be considered self-protecting, no...
