The high power dissipation density in today’s miniature electronic/mechanical systems makes on-chip thermal management crucial. In order to achieve quick-to-evaluate, yet accurate electro-thermal models, needed for the thermal management of microsystems, model order reduction is necessary. In this paper, we use Krylov-subspace methods for the order reduction of a electro-thermal MEMS model, ill...

A modern operating theatre or intensive care unit contains many pieces of electronic equipment, which all have to function safely and reliably in close proximity to each other. To ensure that this can happen, it is vital for those who design, manage or use electro-medical devices to consider electromagnetic compatibility (EMC). In a hospital, the electromagnetic environment can be quite harsh, ...

In this paper, a methodology is proposed for expediting the coupled electro-mechanical finite element modeling of electrostatically actuated MEMS. The proposed methodology eliminates the need for repeated finite element meshing and subsequent electrostatic modeling of the device during mechanical deformation. We achieve this by using an approximation of the charge density on the movable electro...

The paper analyzes the technological process of electro-electroplating-mechanical coating in comparison with a similar without mechanical impact on formed coating.

fabrication, characterization and application of micro-/nano-rods/wires are among the hottest topics in materials science and applied physics. micro-/nano-rod-based structures and devices are developed for a wide-ranging use in various fields of micro-/nanoscience (e.g. biology, electronics, medicine, optics, optoelectronics, photonics and sensors). it is well known that the structure and prope...

OF THE THESIS Damage Detection in Dynamic Systems with Nonlinearities by William Bruce Dunbar Master of Science in Engineering Sciences (Applied Mechanics) University of California, San Diego, 1999 Professor John B. Kosmatka, Chair In general, damage detection can be described by the process of monitoring a physical dynamic (moving) system accompanied by con rmation and assessment of any degrad...

Carpal Tunnel Syndrome (CTS) is sometimes diagnosed post electrical injury. Unfortunately, there is no clear causal connection between electric shock and the electro-diagnostic indications of CTS. One might thus infer that the electro-diagnostic appearance of signal slowing through the carpal tunnel is indicative of electrical injury to the median nerve as opposed to the mechanical compression ...

We present a multi-scale approach to modeling the electro-mechanical behavior of ionic polymers. We start with a detailed elasto-electro-chemical model which allows for nite deformation. We reduce it to one space dimension appropriate for the commonly used sheet con guration, and demonstrate that steady state solutions display an important boundary layer e ect. We conclude with a macroscopic mo...
