We study the dynamics of an electrostatically driven impact microactuator. Impact between moving elements of the microactuator is modeled using the coefficient of restitution. Friction between theâ€¦ (More)

An exact treatment of the propagation of axisymmetric waves in coaxial anisotropic assembly of piezoelectric rod systems is presented. The rod system consists of an arbitrary number of coaxialâ€¦ (More)

Linear and nonlinear static feedback controls are implemented on a nonlinear aeroelastic system that consists of a rigid airfoil supported by nonlinear springs in the pitch and plunge directions andâ€¦ (More)

This paper presents theoretical and experimental results on the problem of bounded acoustic beam reflection at the Rayleigh angle from a fluid-solid interface which is loaded by a thin solid layer.â€¦ (More)

A multiple scales perturbation technique is presented for the propagation of torsional acoustic modes in a clad-rod ultrasonic delay line in which the radius of the core varies sinusoidally in theâ€¦ (More)

Using a parallel three-phase boost converter consisting of two modules, we compare the performances of three nonlinear control schemes. The basic idea, however, can be extended to a system with Nâ€¦ (More)
