the coefficients of the denominator and numerator polynomials are affine in a real uncertain parameter vector δ satisfying the Euclidean norm constraint ||δ||<δ. The concept of stabilizability radius of P(s, δ) is introduced which is the norm bound δs for δ such that every member plant of P(s, δ) is stabilizable if and only if ||δ||<δs. The stabilizability radius can be simply interpreted as the ‘largest......

Polytechnical University, Xi’an 710072, China) Abstract: Considering the incapability of updating operation at high sampling rate, a backward-deduction IIR notch filter was proposed, which can work at high......
the two wick structures was explored. A theoretical capillary force model of skew-grooved wick structure was also developed to calculate its effective capillary radius by comparing with the rectangle... the skewed-grooved wick has a smaller effective capillary radius, its maximum capillary force is 8.64% larger than that of the rectangle-grooved wick. The results indicate that the skew-grooved wick......
