Ranked centroid projection: A data visualization approach based on self-organizing maps
(2006-07)
The Self-Organizing Map (SOM) is an unsupervised neural network model that provides topology-preserving mapping from high-dimensional input spaces onto a commonly two-dimensional output space. In this study, the clustering ...
Advanced retinal imaging: Feature extraction, 2-D registration, and 3-D reconstruction
(2006-12)
In this dissertation, we have studied feature extraction and multiple view geometry in the context of retinal imaging. Specifically, this research involves three components, i.e., feature extraction, 2-D registration, and ...
Resonant terahertz transmission of plasmonic subwavelength hole arrays
(2006-05)
Scope and Method of Study: The purpose of this study was to examine the extraordinary terahertz (THz) transmission through subwavelength hole arrays structured on metals, highly doped and photo-doped silicon. Conventional ...
Piecewise linear delay modeling of digital VLSI circuits
(2006-05)
Scope and Method of Study: One of the most important performance measures of digital logic circuits is the delays of switching signals propagating through the logic gates of the circuit. Circuit simulators such as SPICE ...
Ultra-low power RF receiver based on double-gate CMOS FinFET technology
(2006-05)
In this research, design approaches and methodologies were presented to realize the ultra-low power RF receiver front-end circuits. Moderate inversion operation was explored as a possible method of reducing power consumption ...
