(IEEE, 2009-08)The aim of this paper is to apply an approach that will allow us to consider different mechanical modes of a MEMS cantilever in the form of separate mass-spring-damper equations with the appropriate form of an external ...

(IEEE, 2009-05)In this paper we apply methods of nonlinear dynamics to examine the behavior of the pulsed digital oscillator for microelectromechanical systems (MEMS). We study the regions of existence of oscillations and demonstrate ...

(Optical Society of America, 2009-08-19)In the first of this series of papers [J. Opt. Soc. Am. B 26, 1736 (2009)], a new kinetic model, which includes most of the major photochemical and nonlocal photopolymerization driven diffusion effects, was proposed. ...

(Optical Society of America, 2009-10-11)If we sample a scalar wave field, it becomes periodic in frequency. We examine the cross-terms which occur between these periodic replicas in the Wigner-Ville distribution function of such a signal. We present analytic ...

(World Scientific Publishing, 2009-01)In this paper, we study the behaviour of a MEMS oscillator by applying methods of nonlinear dynamics. We model the system as a kicked damped oscillator and obtain the iterative maps that describe the MEMS system. The ...

(IEEE, 2009-05-24)Recently, several digital phase-locked loops (DPLLs) have been demonstrated to achieve the jitter performance of traditional charge-pump-based analog PLLs. This paper is concerned with a class of DPLLs employing a ...

(Elsevier, 2009-08)This paper examines peat power production in Ireland under the three pillars of energy policy—security, competitiveness and environment. Peat contributes to energy security—as an indigenous fuel, it reduces dependency on ...
-
(IEEE, 2009-08-23)This paper examines the nonlinear dynamics of an alias-locked loop (ALL) which uses an aliasing divider instead of a traditional frequency divider in the feedback loop of a phaselocked loop. A nonlinear model of the ALL ...

(IEEE, 2009-05)The stochastic nature of wind alters the unit commitment and dispatch problem. By accounting for this uncertainty when scheduling the system, more robust schedules are produced, which should, on average, reduce expected ...

(Optical Society of America, 2009-03-01)Photopolymer materials are practical materials for use as holographic recording media. To further develop such materials, a deeper understanding of the photochemical mechanisms present during the formation of holographic ...
