Main Aspects of the Space-Time Computational FSI Techniques and Examples of Challenging Problems Solved
(2014-01)Flow problems with moving boundaries and interfaces include fluid--structure interaction (FSI) and a number of other classes of problems, have an important place in engineering analysis and design, and offer some formidable ... -
Metallic 1T phase source/drain electrodes for field effect transistors from chemical vapor deposited MoS2
(2014)Two dimensional transitionmetal dichalcogenides (2D TMDs) offer promise as optoelectronic materials due to their direct band gap and reasonably good mobility values. However, most metals form high resistance contacts on ... -
A New Imaging Platform for Visualizing Biological Effects of Non-Invasive Radiofrequency Electric-Field Cancer Hyperthermia
(2015)Herein, we present a novel imaging platform to study the biological effects of non-invasive radiofrequency (RF) electric field cancer hyperthermia. This system allows for real-time in vivointravital microscopy (IVM) imaging ... -
New insights into the properties and interactions of carbon chains as revealed by HRTEM and DFT analysis
(2014)Atomic carbon chains have raised interest for their possible applications as graphene interconnectors as the thinnest nanowires; however, they are hard to synthesize and subsequently to study. We present here a reproducible ... -
Nonlinear MDOF System Survival Probability Determination Subject to Evolutionary Stochastic Excitation
(2016)An approximate technique for assessing the reliability of nonlinear multi-degree-of-freedom (MDOF) systems subject to a non-stationary stochastic excitation vector is developed. The proposed technique can be construed as ... -
Numerical investigation of coexisting high and low amplitude responses and safe basin erosion for a coupled linear oscillator and nonlinear absorber system
(2014)Over the last half century, numerous nonlinear variants of the tuned mass damper have been developed in order to improve attenuation characteristics. In the present study, the performance of a linear oscillator and an ... -
On the development of objective metrics for surgical skills evaluation based on tool motion
(2014)A key competency requirement in endovascular surgery is to optimally visualize and utilize pre-shaped catheters to navigate complex vascular anatomy, yet current performance assessment techniques are limited to grading ... -
Output-Only Structural Health Monitoring for Deepwater Risers: Experimental Study of Wavelet Modified SOBI and Distributed Force Index Algorithm
(2014)Risers are the conduits between the subsea wellhead and the drilling/production platform for development, production, gas lift or water injection purposes, which are also one of the most important and the most vulnerable ... -
Paintable Battery
(2012)If the components of a battery, including electrodes, separator, electrolyte and the current collectors can be designed as paints and applied sequentially to build a complete battery, on any arbitrary surface, it would ... -
Practical high-fidelity frequency-domain force and location identification
(2015)Identifying the force information and location of an impact event is important for predicting and/or monitoring potential damage to the structures. Directly measuring the impact event and/or locating the impact force is ... -
A Pre-Clinical Framework for Neural Control of a Therapeutic Upper-Limb Exoskeleton
(2013)In this paper, we summarize a novel approach to robotic rehabilitation that capitalizes on the benefits of patient intent and real-time assessment of impairment. Specifically, an upper-limb, physical human-robot interface ... -
Programmable bio-nano-chip system: a flexible point-of-care platform for bioscience and clinical measurements
(2015)The development of integrated instrumentation for universal bioassay systems serves as a key goal for the lab-on-a-chip community. The programmable bio-nano-chip (p-BNC) system is a versatile multiplexed and multiclass ... -
