Programmable ultrasound color flow system
(2000)Ultrasound color flow systems are widely used in medical imaging because these are safe, noninvasive, and relatively inexpensive and displays images in real time. However to meet the real time requirement, these systems ... -
Programming Molecules and Cells: Design Architectures for Chemical Reaction and Gene Regulatory Networks
(2014-04-30)The stages of cell differentiation are often illustrated as a sequence of events and chemical cues that move a cell from one state to another. Differentiated cells send and receive signals to compute functions on their ... -
Proton Conducting Devices and Materials
The flow of protons is vital in biology, driving natural processes like the production of adenosine triphosphate (ATP) (1). Micro-scale fluctuations in pH can provide insight into neural activity and regulate cellular ... -
A Prototype System and Circuits for the Development of an Implantable H-bridge Stimulator ASIC in a Bulk CMOS Process
The opportunity to introduce nanometer sized circuits and systems into the body to treat or cure mental disorders, physical injuries, and genetic disabilities has put us at the forefront of a burgeoning industry. Implantable ... -
Quality-Driven Cross Layer Design of Video Transmissions over MIMO Systems
Mobile data traffic has been exponentially increasing during the past years. With the prevalence of video-enabled mobile devices such as smart phones, more than half of the total mobile data traffics are attributed to ... -
Radio Frequency Synthesis for Power-Constrained Systems
This thesis serves as a demonstration of the feasibility of performing multi-\si{\giga\hertz} frequency synthesis at voltage levels typical of certain energy harvesting elements, namely, photovoltaic cells and thermoelectric ... -
Random Access over Multi-Packet Reception Channels: A Mean-Field Approach
This thesis addresses the problem of Multi-Packet Reception (MPR) for random access scenarios in Wireless LAN type infrastructure network. Our results builds on a recently proposed physical-layer network coding mechanism ... -
Rank and Sparsity in Language Processing
(2013-11-14)Language modeling is one of many problems in language processing that have to grapple with naturally high ambient dimensions. Even in large datasets, the number of unseen sequences is overwhelmingly larger than the number ... -
Readout Driver Firmware Development for the ATLAS Insertable B-Layer
During the Large Hadron Collider shutdown from 2013 to 2014 a fourth silicon layer, called the Insertable-B Layer (IBL), was inserted inside the existing ATLAS Pixel Detector. The IBL uses the state-of-the-art FE-I4 front-end ... -

Real-Time Haptic Interaction with Remote Environments using Non-contact Sensors
(2013-11-14)Haptic interaction with a haptic device has traditionally been limited to interaction with purely virtual objects or to static range scans of physical objects. Haptic interaction with physical objects at a distance has not ... -
Real-time Quantitative Assessment of Surgical Skill
(2012-09-13)Faculty surgeons must accurately evaluate trainee performance in an apprenticeship training model in order to establish the skill level of their trainees and minimize their iatrogenic impact on patients. This is a subjective, ... -
Real-time video postprocessing algorithms and metrics
(2003)The main purpose of video postprocessing is to reduce compression artifacts, such as blocking, ringing, and temporal noise. Many existing postprocessing algorithms either require very high computational cost or cannot ... -
Recognition of Human Actions based on 3D Pose Estimation via Monocular Video Sequences
We propose a system to recognize both isolated and continuous human actions, from monocular video sequences, based on 3D human pose estimation and cyclic hidden Markov models (CHMMs). First, for each frame in a monocular ... -

Reduced Moment-Based Models for Oxygen Precipitates and Dislocation Loops in Silicon
(2013-07-25)The demand for ever smaller, higher-performance integrated circuits and more efficient, cost-effective solar cells continues to push the frontiers of process technology. Fabrication of silicon devices requires extremely ... -
Reference clock design for low power and low phase noise with temperature compensation
Low power and low phase noise RF frequency references are essential for applications such as high performance ADCs, high speed serial data links, and low power radios. They constitute a multi-billion dollar market in today’s ... -
Remote sensing of localized ion acoustic waves with multistatic passive radar
(2006)Our goal is to contribute to the understanding of ionospheric E region physics by developing a linear fluid theory of E region plasma density irregularities as well as new experimental techniques for radar remote sensing ... -
RFID: A Communication System Perspective
(2014-04-30)Backscatter modulation is the keystone behind the technical and commercial success of Radio Frequency IDentification (RFID) in applications that require fast, efficient, and automatic identification of tagged objects. Owing ... -
Robust and Consistent Human Tracking Within Camera and Across Multiple Cameras
(2013-07-25)This dissertation strives to develop a robust and consistent tracking system that tracks humans within a single camera and across multiple cameras. We present three main parts of our research: single camera tracking, ...
