• #### 3-D segmentation and volume estimation of radiologic images by a novel, feature driven, region growing technique ﻿

(1992)
Magnetic Resonance (MR) imaging is a 3-D, multi-slice, radiological technique that acquires multiple intensities corresponding to each voxel. The transverse relaxation time, T$\sb1$, and the axial relaxation time, T$\sb2$, ...
• #### A closed-loop model of the ovine cardiovascular system ﻿

(2003)
The conscious sheep is an important large animal model for the study of human cardiovascular and cardiopulmonary system. In this study we develop a closed-loop mathematical model of its cardiovascular system. A distributed ...

• #### A model of sarcolemmal calcium(2+) currents and cytosolic calcium(2+) transients in a rat ventricular cell ﻿

(2000)
We have developed a mathematical model of the L-type Ca2+ current and cytosolic Ca2+ transient, which is based on data from whole-cell voltage clamp experiments on rat ventricular myocytes. Modified Goldman-Hodgkin-Katz ...
• #### A phase sensitivity based method for prediction of modes of behavior in quadrupedal locomotion ﻿

(1996)
The objective of this study is development of prediction methods for characterizing the electrical behavior of ring type central pattern generators (CPGs). A mathematical model of the prototypical bursting neuron R15 from ...

(1972)
• #### Approaches for respiratory motion compensation in positron emission tomography imaging ﻿

(2008)
Respiratory patient motion often causes image blur and inaccurate quantitation results in positron emission tomography (PET) imaging. Traditional gated acquisition approach corrects motion artifacts by generating a snapshot ...
• #### Binaural localization using interaural cues ﻿

(1990)
Major nuclei of the superior olivary complex--the lateral superior olive (LSO) and the medial superior olive (MSO) are presumed to play a major role in the localization of sound signals using interaural level and interaural ...
• #### Clinical Applications of a Human Cardiovascular-Respiratory System Model: Studying Ventricular Mechanics in Disease and Treatment ﻿

(2012)
Large-scale modeling allows for a broad mechanistic view of a cardiopulmonary disease, often beyond what can be observed clinically. Our group has developed a large-scale model of the human cardiovascular-respiratory system ...

(1975)
• #### Design of a Fast, Efficient and Controlled DNA Shearing System Based on Lateral Acoustic Waves ﻿

(2012)
With the continuous research and advances in Deoxyribonucleic acid (DNA) sequencing technologies, the need for an efficient DNA shearing system has increased more than ever before. In this thesis, we propose a fast, efficient ...

(1976)
• #### Inverse model for the extraction of biological parameters from ovarian tissue fluorescence spectra and multivariate classifiers for tissue diagnosis ﻿

(2007)
We present an inverse model to decompose bulk fluorescence spectra and extract tissue biological parameters. By deconvolving the effects of absorption and scattering from measured spectra, we are able to extract the intrinsic ...
• #### Issues in myoelectric teleoperation of complex artificial hands ﻿

(1995)
This dissertation introduces a novel method of teleoperation of complex anthropomorphic robotic hands: converting the myoelectric signal generated by an operator's muscles during movement into robot commands replicating ...

(1972)
• #### Models of electrical activity, calcium concentration, and synaptic plasticity in Aplysia neurons ﻿

(1991)
Mathematical models of two Aplysia neurons simulate salient features of the electrical and chemical activity of these neurons. First, the endogenous burster R15 was modeled as a Hodgkin-Huxley (HH) type membrane equivalent ...
• #### Motion-corrected treadmill nuclear angiography ﻿

(2003)
First-pass radionuclide angiography (RNA) of the human heart is performed during peak treadmill exercise using a Multiwire Gamma Camera (MWGC) and an intravenous injection of ultra-short-lived radionuclide Tantalum-178. ...
• #### Optimization of novel developments in Positron Emission Tomography (PET) imaging ﻿

(2012)
Positron Emission Tomography (PET) is a widely used imaging modality for diagnosing patients with cancer. Recently, there have been three novel developments in PET imaging aiming to increase PET image quality and quantification. ...
