In the multi-paralleled grid-connected inverters system, harmonic oscillations may be deteriorated or even lead to system instability by the coupling between the inverters and the grid impedance. This paper presents a quantify method to determine whi

The two-dimensional problem of determining the steady-state field of enforced joint gravitational motions of incompressible fluid and a round elastic plate covering its surface has been considered. The motions are caused by a point load moving period

An image hiding scheme based on stochastic moiré gratings is proposed, discussed, and illustrated in this paper. The proposed scheme is based on a counter-intuitive optical feature of specially designed stochastic moiré gratings when similar images
