Jae Won Lee, Internal Distance(s) Mid - Career Retrospective
No full textCatalog of an exhibition held at the Oakland University Art Gallery, January 10 – February 22, 2009. Contains essay by Dick Goody.Excerpt from essay by Dick Goody: There is something universal in the act of contemplating nature; there is something contextual too. For example, imagine walking down a path and homing in on a particularly attractive leaf; now, pick up the leaf and weigh its beauty. But also consider all the other things that come to mind. The work of Jae Won Lee focuses on the formalistic beauty of nature. All the other things that come to mind, which inform her work, she consigns obliquely away to be separately archived

Optimal placement of piezoelectric actuators in intelligent structures using genetic algorithms
No full textStudy of a reduced and internally biased oxide wafer PZT actuator and its integration with shape memory alloy
No full textLarge displacement piezoelectric actuators of a new kind-RAINBOW (reduced and internally biased oxide wafer) actuators, which are composed of reduced and unreduced layers-were prepared from PZT (Pb(ZrxTi1-x)O-3) by chemical reduction. The distribution of stress inside the RAINBOW structure and its actuating properties were both studied. It is found that the optimal ratio of reduced layer thickness for the RAINBOW structure is 0.3; reduced RAINBOW PZT has a lower resonance frequency and a three-times-larger displacement than traditional PZT; furthermore, the possibility of integration of PZT and SMA (shape memory alloy) was also explored. The PVD (physical vapor deposition) method was applied to deposit SMA coatings on the reduced layers of RAINBOW PZT patches. Results of mechanical and actuating experiments show that this is a reasonable idea for manufacturing actuators with better performance.This work was financially supported by the Chinese

Optimal placement of piezoelectric sensors and actuators for vibration control of a composite plate using genetic algorithms
No full textIn this paper, the placement of piezoelectric sensors and actuators has been studied. Genetic algorithms have been used to find efficient locations of piezoelectric sensors and actuators of a smart composite place. Locations of both sensors and actuators have been determined with consideration of controllability, observability and spillover prevention. The composite specimen with piezoelectric sensors and actuators has been prepared according to the optimization result. The experimental vibration control shows significant vibration reduction for the controlled modes with little effect on the residual modes. In addition, the closed loop system is observed to be robust with respect to system parameter variations.The present work was supported by the Korea Science and

Active damping enhancement of composite plates with electrode designed piezoelectric materials
No full textThe characteristics of the actuation effectiveness of piezo-laminated plates have been investigated. Finite element procedures based on the first order shear deformation theory have been developed. The actuation effectiveness of each portion of a piezoelectric material has been obtained. For a twisting mode, a large amount of cancel out effect is observed. The first order perturbation analysis shows that in case of direct negative velocity feedback, control performance increases when the cancel out effect decreases. A simple and effective electrode design method has been suggested with the idea of electrode shaping such as a combination of subareas without cancel out effects for the modes under consideration. In the present study, a cantilevered plate with piezoelectric polymer on both surfaces is considered. Best electrode shapes which have extremum values for each cost function are obtained.The authors gratefully acknowledge the support of this work by Korea Science and Engineering Foundation (project No.93-0700-02-01-3)
