Characterization of Suspended Piezoelectrically Transduced Resonators

This report presents the characterization of singly-clamped and doubly-clamped resonator devices. Resistance tests were performed to ensure adequate top-to-bottom insulation, allowing the characterization work to proceed. The piezoelectric characteristics ...

Dynamics of optical forces and torques in plasmonic systems: a surface integral equation

Olivier Martin, Karim Achouri, Andrei Kiselev

A novel approach is introduced to determine the time evolution of optical forces and torques on arbitrary shape nanostructures by combining Maxwell's stress tensor with the surface integral equation method (SIE). Conventional time averaging of Maxwell’s st ...

SIMPLE code: Optical properties with optimal basis functions

Nicola Marzari, Gianluca Prandini, Paolo Umari

We present SIMPLE, a code developed to calculate optical properties of metallic and insulating extended systems using the optimal basis method originally proposed by E.L. Shirley in 1996. Two different approaches for the evaluation of the complex dielectri ...

A 3D moving mesh Finite Element Method for two-phase flows

John Richard Thome, Navid Borhani, Gustavo Rabello Dos Anjos

A 3D ALE Finite Element Method is developed to study two-phase flow phenomena using a new discretization method to compute the surface tension forces. The computational method is based on the Arbitrary Lagrangian-Eulerian formulation (ALE) and the Finite E ...

Together Anywhere, Together Anytime, Technologies for Intimate Interactions

Petr Motlicek, Danil Korchagin

Modern social media systems are geared to serving weak ties: informal collections of individuals acting in relative isolation. But what about strong ties: the family and friends who form life's inner circle? More and more people are living apart. Can techn ...

An Improved CFD Tool to Simulate Adiabatic and Diabatic Two-Phase Flows

Bogdan Alexandru Nichita

With increasing computer capabilities, numerical modeling of two-phase flows has developed significantly over the last few years. Although there are two main categories, namely 'one' fluid and 'two' fluid methods, the 'one' fluid methods are more commonly ...

A four-motor drive supplied from a triple three-phase voltage source inverter

Drazen Dujic

Since control of a three-phase machine requires only two currents, it is possible to independently control a number of three-phase machines using reduced-switch-count voltage source inverter (VSI) topologies. One such configuration consists of n three-phas ...
