Active Control of MEMS Resonator Parameters via Electromechanical Feedback

M. Hodjat-Shamami [1], F. Ayazi [1],
[1] Georgia Institute of Technology, Atlanta, GA, USA

MEMS resonators have been recently adopted in a wide variety of timing, sensing, and actuation applications. The ability to control the dynamics of resonance, namely the resonance frequency and quality factor of these resonators is crucial in achieving high precision performance within ... Read More

A Prediction of Energy Piles’ Long-Term Operation Using a Coupled Thermo-Hydro-Geomechanical Model

T. Vu [1], L. Medina [1], D. de la Cruz [1], J. Ramirez [1], B. Xu [1]
[1] University of Texas - Rio Grande Valley, Edinburg, TX, USA

An energy pile harvests geothermal energy to heat and cool a building by integrating ground heat exchanger (GHX) pipes into the building’s deep foundation, and extracts heat from the ground in the winter to heat buildings and injects heat into the ground during the summer. In areas with ... Read More

A Partial Verification of a COMSOL® Example Problem on the Fluid-Structure Interaction in a Network of Blood Vessels

J. T. Fong [1], A. Heckert [1], J. J. Filliben [1]
[1] National Institute of Standards & Technology, Gaithersburg, MD, USA

Finite element method (FEM)-based solutions are known to contains errors and uncertainties due to at least four mathematical (M) and four physical (P) sources, namely, (M-1) mesh density or degrees of freedom, (M-2) mesh element types, (M-3) mesh quality such as mean aspect ratio, (M-4) ...

A Microfluidic Platform for Electrochemical Concentration and Detection

C. F. Ivory [1], D. E. Molina [1],
[1] Washington State University, Pullman, WA, USA

A poly(methyl methacrylate) (PMMA) microfluidic platform with a hot-embossed microchannel, 150 mm wide and 20 mm deep, was developed for multiple purpose detection using electrochemical methods. This device is able to accommodate a three-electrode system encased in 1/16" diameter PEEK ... Read More
