A GI-FMF for multi-parameter sensing is proposed, utilizing interaction between multiple acoustic modes in SBS process. Consequently simultaneous temperature and strain measurement may be achieved with a sensitivity of five times larger than conventional methods.
NBTI of BOX layer induced degradation for thin layer SOI field p-channel LDMOS is investigated by experiment, modeling and simulation. Decrease in drain current (Id) under high negative BG voltage (VBG) stressing is observed, which is ascribed to the positive fixed oxide charge and interface charge in BOX layer induced by NBTI. The NBTI conduction modulation model is proposed to elevate the positive...
Abstract - Overheated electrical joints due to loose connection are often precursors of electric fires, arc faults, and arc flash in electrical systems. This paper is about the formation mechanism and behavior characteristics of loose connection induced overheated electrical joints. Specific experiments were conducted on busbar joints and systems with currents ranging from 100 A up to 5000 A. The...
Electrical cables are widely used in urban electrical transmission. It is necessary to monitor whether it operate normally or not. The conductor temperature is a key parameter should be monitored. However the conductor temperature of underground cables is very hard to measure for technical difficulties, the other option is calculation. The conductor temperature is associated with the temperature and...
Cable ampacity is always concerned by the electric power operating and scheduling engineerer. Calculation of cable ampacity is quite complex and calculation error is hard to evaluate because there are many influencing factors and some factors is changeable. Furthermore, on account of current power cable's manufacture, laying and operation circumstances are much different from before which also will...
Recently, it was discovered that by defect modification, the electromechanical responses of P(VDF-TrFE) based ferroelectric polymers can be modified significantly. Here, we present a room temperature phase diagram which illustrates the compositions of two classes of PVDF based polymers investigated in this paper. In the compositions at PVDF homopolymer, by including bulky monomers such as CTFE (chlorotrifluoroethylene),...
