Abstract: This article explores criteria necessary for reliable communication between electric vehicles (EVs) and electric vehicleservice equipment (EVSE). Data will demonstrate that a G3-PLC system has already met the criteria established by the automotiveand utility industries. Multiple internat ...
Some algorithms of variable step size LMS adaptive filtering are studied．The VS—LMS algorithm is improved．
Another new non-linear function between肛and e(／ t)is established．The theoretic analysis and computer
simulation results show that this algorithm converges more quickly than the origina1． ...
This paper introduces an affine invariant of trapezia, and the explicit constraint equation between the intrinsic matrix of a camera and the similarity invariants of a trapezium are established using the affine invariant. By this constraint, the inner parameters, motion parameters of the cameras and ...
