Experiments towards size and dopant control of germanium quantum dots for solar applications
(2016)While the literature for the doping of silicon quantum dots (QDs) and nanocrystals (NCs) is extensive, reports of doping their germanium analogs are sparse. We report a range of attempts to dope Ge QDs both during and ... -
Design and Optimization of an EEG-Based Brain Machine Interface (BMI) to an Upper-Limb Exoskeleton for Stroke Survivors
(2016)This study demonstrates the feasibility of detecting motor intent from brain activity of chronic stroke patients using an asynchronous electroencephalography (EEG)-based brain machine interface (BMI). Intent was inferred ... -
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 ... -
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 ... -
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 ... -
Design of a parallel-group balanced controlled trial to test the effects of assist-as-needed robotic therapy
(2015)In this methods paper, we report on the design of a clinical study testing the efficacy of a newly developed control scheme for robot-aided rehabilitation. To measure the value added by a new control scheme, we pursued a ... -
A Comprehensive Probabilistic Framework to Learn Air Data from Surface Pressure Measurements
(2015)Use of probabilistic techniques has been demonstrated to learn air data parameters from surface pressure measurements. Integration of numerical models with wind tunnel data and sequential experiment design of wind tunnel ... -
Characterization of a hand-wrist exoskeleton, READAPT, via kinematic analysis of redundant pointing tasks
(2015)Training coordinated hand and wrist movement is invaluable during post-neurological injury due to the anatomical, biomechanical, and functional couplings of these joints. This paper presents a novel rehabilitation device ... -
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 ... -
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 ... -
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 ... -
Universal ac conduction in large area atomic layers of CVD-grown MoS2
(2014)Here, we report on the ac conductivity [σ’(ω); 10 mHz < ω < 0.1 MHz] measurements performed on atomically thin, two-dimensional layers of MoS2 grown by chemical vapor deposition (CVD). Σ’(ω) is observed to display a ... -
Hydrogen Diffusion and Stabilization in Single-Crystal VO2 Micro/Nanobeams by Direct Atomic Hydrogenation
