An effective way of measuring partial discharge (PD) for GIS is the UHF method, by which both PD detection and location can be realized. PD location is based on time-off-light calculation in which travelling paths of electromagnetic signals between two sensors are assumed to be axially along the centre of GIS. The location is therefore normally obtained by solving a one dimensional problem, as if...
In this paper, phase change random access memory (PCRAM) devices with two different geometric configurations were studied. The geometry effect on device functionalities in terms of thermal and electrical properties has been analyzed by simulation and experiments. Based on 0.35mum technology, 128 bits PCRAM array integrating with CMOS as the selection device were fabricated. The two types of PCRAM...
