Roll, Pitch and Yaw Torque Control for a Robotic Bee
(2012-11-19)
In the last decade, the robotics community has pushed to develop increasingly small, autonomous flapping-wing robotic vehicles for a variety of civilian and military applications. The miniaturization of these vehicles has ...
Extracting Spatiotemporal Word and Semantic Representations from Multiscale Neurophysiological Recordings in Humans
(2012-09-13)
With the recent advent of neuroimaging techniques, the majority of the research studying the neural basis of language processing has focused on the localization of various lexical and semantic functions. Unfortunately, ...
Content-Aware Manipulations for Image and Video Collections
(2012-08-17)
Digital photography and videography have become ubiquitous. With ever-cheaper and
more capable cameras, found in dedicated devices and, increasingly, in multipurpose
smartphones and tablets, it is now easier than ever ...
Nanobeam Cavities for Reconfigurable Photonics
(2012-11-19)
We investigate the design, fabrication, and experimental characterization of high quality factor photonic crystal nanobeam cavities, with theoretical quality factors of \(1.4 × 10^7\) in silicon, operating at ~1550 nm. By ...
Design and Performance of Insect-Scale Flapping-Wing Vehicles
(2012-08-10)
Micro-air vehicles (MAVs)—small versions of full-scale aircraft—are the product of a continued path of miniaturization which extends across many fields of engineering. Increasingly, MAVs approach the scale of small birds, ...
The Response of Stratospheric Water Vapor to a Changing Climate: Insights from In Situ Water Vapor Measurements
(2012-10-31)
Stratospheric water vapor plays an important role in the Earth system, both through its role in stratospheric ozone destruction and as a greenhouse gas contributing to radiative forcing of the climate. Highly accurate water ...
Wetting in Color
(2012-11-06)
Colorimetric litmus tests such as pH paper have enjoyed wide commercial success due to their inexpensive production and exceptional ease of use. However, expansion of colorimetry to new sensing paradigms is challenging ...
Dissecting Motor Adaptation in Visually Guided Reaching Movements
(2012-11-06)
Movement is essential to human life because it provides us with the freedom of mobility and the power to affect our surroundings. Moreover, movements are vital to communication: from hand and finger movements when writing, ...
Periodic Pulsed Controllability with Applications to NMR
(2012-11-06)
In this thesis we study a class of problems that require simultaneously controlling a large number of dynamical systems, with varying system dynamics, using the same control signal. We call such problems ensemble control ...
Probabilistic Algorithms for Information and Technology Flows in the Networks
(2012-10-16)
This thesis studies several probabilistic algorithms for information and technology flow in the networks. Information flow refers to the circulation of information in social or communication networks for the purpose of ...
