Colloidal Quantum Dots and J-Aggregating Cyanine Dyes for Infrared Photodetection
(2012-12-13)
The emergence of nanostructured semiconducting materials enables new approaches toward the realization of photodetectors that operate in the technologically important near- and short-wave infrared (NIR and SWIR) spectral ...
Accelerated Cardiovascular Magnetic Resonance Imaging Using Radial Acquisition with Compressed Sensing
(2012-12-13)
Magnetic resonance imaging (MRI) is a medical imaging technique that can visualize internal organs for examination and diagnosis. It is non-invasive and ionizing radiation-free, and provides good contrast between different ...
Deploying Affect-Inspired Mechanisms to Enhance Agent Decision-Making and Communication
(2012-12-20)
Computer agents are required to make appropriate decisions quickly and efficiently. As the environments in which they act become increasingly complex, efficient decision-making becomes significantly more challenging. This ...
Mechanical Intelligence in Millimeter-Scale Machines
(2012-12-19)
Advances in millimeter-scale fabrication processes have enabled rapid progress towards the development of flapping wing micro air vehicles with wing spans of several centimeters and a system mass on the order of 100mg. ...
Robotic Catheters for Beating Heart Surgery
(2012-12-12)
Compliant and flexible cardiac catheters provide direct access to the inside of the heart via the vascular system without requiring clinicians to stop the heart or open the chest. However, the fast motion of the intracardiac ...
Oxide Thermoelectrics: The Role of Crystal Structure on Thermopower in Strongly Correlated Spinels
(2012-08-10)
This dissertation reports on the synthesis, structural and thermal characterization and electrical and thermal transport properties of a variety of strongly correlated spinels. General structure property relationships for ...
Development and Field-Deployment of an Absorption Spectrometer to Measure Atmospheric HONO and NO2
(2012-07-20)
Field observations show daytime HONO levels in urban, rural and remote environments are greater than those expected at photostationary state, that is, balance between production by \(NO+OH\) reaction and loss by UV-photolysis ...
Soft Active Materials for Actuation, Sensing, and Electronics
(2012-07-24)
Future generations of robots, electronics, and assistive medical devices will include systems that are soft and elastically deformable, allowing them to adapt their morphology in unstructured environments. This will require ...
Coordinated Resource Management in Networked Embedded Systems
(2012-11-06)
This dissertation shows that with simple programming abstractions, network-wide resource coordination is efficient and useful for programming embedded sensor networks. Existing systems have focused primarily on managing ...
Bioinspired, Dynamic, Structured Surfaces for Biofilm Prevention
(2012-11-14)
Bacteria primarily exist in robust, surface-associated communities known as biofilms, ubiquitous in both natural and anthropogenic environments. Mature biofilms resist a wide range of biocidal treatments and pose persistent ...
