Multiple-User Quantum Optical Communication
A fundamental understanding of the information carrying capacity of optical channels requires the signal and physical channel to be modeled quantum mechanically. This thesis considers the problems of distributing multi-party ...
Subglottal coupling and vowel space: an investigation in quantal theory.

Multiplexing, Scheduling, and Multicasting Strategies for Antenna Arrays in Wireless Networks
A transmitter antenna array has the ability to direct data simultaneously to multiple receivers within a wireless network, creating potential for a more integrated view of algorithmic system components. In this thesis, ...
Bipolar Thermoelectric Devices
The work presented here is a theoretical and experimental study of heat production and transport in bipolar electrical devices, with detailed treatment of thermoelectric effects. Both homojunction and heterojunction ...
An Ultra-Low-Power Programmable Analog Bionic Ear Processor
We report a programmable analog bionic ear (cochlear implant) processor in a 1.5µm BiCMOS technology with a power consumption of 211µW and 77dB dynamic range of operation. The 9.58mm x 9.23mm processor chip runs on a 2.8V ...
Colliding and Moving Bose-Einstein Condensates: Studies of superfluidity and optical tweezers for condensate transport
In this thesis, two different sets of experiments are described. The first is an exploration of the microscopic superfluidity of dilute gaseous Bose-Einstein condensates. The second set of experiments were performed using ...
Tactual Display of Consonant Voicing to Supplement Lipreading
This research is concerned with the development of tactual displays to supplement the information available through lipreading. Because voicing carries a high informational load in speech and is not well transmitted through ...
A Low Power Wide Dynamic Range Envelope Detector
We report a 75dB, 2.8mW, 100Hz-10kHz envelope detector in a 1.5mm 2.8V CMOS technology. The envelope detector performs input-dc-insensitive voltage-to-currentconverting rectification followed by novel nanopower current-mode ...
Global Estimation of Precipitation Using Opaque Microwave Bands
This thesis describes the use of opaque microwave bands for global estimation of precipitation rate. An algorithm was developed for estimating instantaneous precipitation rate for the Advanced Microwave Sounding Unit ...
