Low-bias gate tunable terahertz plasmonic signatures in chemical vapour deposited graphene of varying grain size
(Institute of Electrical and Electronics Engineers (IEEE), 2016-02)
We report the characterization of centimeter sized graphene field-effect transistors with ionic gating which enables active frequency and amplitude modulation of terahertz (THz) radiation. Chemical vapour deposited graphene ...
Mapping and determining the center of mass of a rotating object using a moving observer
(SAGE Publications, 2018-01)
For certain applications, such as on-orbit inspection of orbital debris, defunct satellites, and natural objects, it is necessary to obtain a map of a rotating object from a moving observer, as well to estimate the object’s ...
Location utility-based map reduction
(Institute of Electrical and Electronics Engineers, 2015-07)
Maps used for navigation often include a database of location descriptions for place recognition (loop closing), which permits bounded-error performance. A standard pose-graph SLAM system adds a new entry for every new ...
Synchronization stability of lossy and uncertain power grids
(Institute of Electrical and Electronics Engineers (IEEE), 2015-07)
Direct energy methods have been extensively developed for the transient stability analysis and contingency screening of power grids. However, there is no analytical energy functions proposed for power grids with losses, ...
Hesitant steps from the artificial skin to organ regeneration
(Oxford University Press (OUP), 2018-06)
This is a historical account of the steps, both serendipitous and rational, that led my group of students and colleagues at MIT and Harvard Medical School to discover induced organ regeneration. Our research led to methods ...
Preliminary Field Test Results From a Photovoltaic Electrodialysis Brackish Water Desalination System in Rural India
(American Society of Mechanical Engineers, 2018-08)
Brackish water desalination is crucial to meet basic drinking water needs in rural India. Solar photovoltaic powered electrodialysis (PV-ED) has been justified as a more cost-effective solution than the current dominant ...
Understanding why the thinnest SiNx interface in transition-metal nitrides is stronger than the ideal bulk crystal
(American Physical Society, 2010-05)
One-monolayer-thick SiNx interfacial layer in superhard nanocomposites, consisting of 3–4 nm size TiN nanocrystals joined by that layer, is stronger than a bulk SiNx crystal due to valence charge transfer from the metallic ...
An Experimental Evaluation of Vortex-Induced Vibration of a Riser Bundle With Gaps
(American Society of Mechanical Engineers (ASME), 2009-06)
VIV model test results are presented for a bundle of three parallel pipes all lying in the same plane, similar to a riser with large kill and choke lines. The rigid model was attached to a spring-mounted frame in the MIT ...
Online reporting for malaria surveillance using micro-monetary incentives, in urban India 2010-2011
(BioMed Central Ltd, 2012-02)
Background The objective of this study was to investigate the use of novel surveillance tools in a malaria endemic region where prevalence information is limited. Specifically, online reporting for participatory epidemiology ...
Pessimistic Bilevel Optimization
(Society for Industrial and Applied Mathematics, 2013-02)
We study a variant of the pessimistic bilevel optimization problem, which comprises constraints that must be satisfied for any optimal solution of a subordinate (lower-level) optimization problem. We present conditions ...
