The off-line discharge between the pantograph and catenary (PAC) occurs frequently in actual operation of an electric locomotive, which affects quality received current service life pantograph. experiments on PAC are mainly low-power ones models established static. To study electrical behaviors during relative motion under working conditions, this paper, voltage contact wire (CW) its measured. And rise, fall reciprocating motions investigated by combining a finite element method (FEM) model...
Rate control (RC) is a key technology in video coding which mainly responsible for adapting the compressed quality as much possible under limited bandwidth. Typical RC methods consist of initial quantization parameters I-frames decision and updating procedures. However, on one hand, parameter (QP) decided by sum absolute transformed difference (SATD) computation, time consuming low delay applications. On other are only updated ignoring distortion characteristics inter frame, cannot achieve...
The intelligent metering system, using the technique of phase-locked frequency multiplier to discrete wave student dormitory electronic signal, obtains TRMS measurement. neural networks is applied current identify high-power load and computer, stopping from violating electric power regulations. system has functions timing on off, remote control reading. It can also meet special requirements electricity management for studentspsila dorm, such as overload judgment, illegal appliances...
