This paper investigates the nano-positioning control for a piezoelectric actuator system with states time-delay via multiple Lyapunov functions. The multiple Lyapunov functions can relax stabilization conditions derived by the traditional single Lyapunov function. First, the Bouc-Wen equation establishes the mathematical model of a piezoelectric actuator system. To reduce the nonlinear hysteres...

Comfort, reliability, functionality performance which provide a longer life cycle requires thourogh understanding and analysis of the vibrations, this is a general rule for most of the static and dynamic when studying the functionality performance of any application. Vibrations is an extremely important issue to consider when designing various systems.The hysteresis in the dampers is very impor...

The following terminology will be used. The clause containing the ellipsis (dann besbI£he ieh immer den Peter "then I always -vts# Peter" in ( 1b)) is called ellipsis clause. The constituent --other than dann ("then"), immer ("always") and possibly other particles-that remains expressed in the ellipsis clause is called the remnant (den Peter "the Peter") . The clause from which the elided infor...

Wen and colleagues use a non-calibrated creatinine concentration to estimate glomerular filtration rate (GFR). Even if such non-calibration has little importance for mortality linked to CKD, it could have serious consequences on prevalence data. 2 These prevalence data are thus not easy to compare with those of the US population, for which the newly expressed Modification of Diet in Renal Disea...

Quantum-mechanically coupled wen systems consisting of two GaAs wells 30 A thick separated by an Alo.s GIlo.s As barrier whose thickness was varied from 12 to 40 A have been grown by metalorganic chemical vapor deposition. The photoluminescence spectra of these systems indicated the splitting of a degenerate single well state into a doublet state, a symmetrical state, and an antisymmetric state...
