Iterative algorithms for lossy source coding
(Massachusetts Institute of Technology, 2006)
This thesis explores the problems of lossy source coding and information embedding. For lossy source coding, we analyze low density parity check (LDPC) codes and low density generator matrix (LDGM) codes for quantization ...
Quantification of blood Gd-DTPA levels : implications on dosing dGEMRIC
(Massachusetts Institute of Technology, 2005)
Delayed gadolinium enhanced magnetic resonance imaging of cartilage (dGEMRIC) is a novel technique that allows early diagnosis of osteoarthritis (OA). Under the current protocol, subjects are injected 0.2mmol of an MRI ...
StarLogo TNG : the convergence of graphical programming and text processing
(Massachusetts Institute of Technology, 2006)
StarLogo TNG is a robust graphical programming environment for secondary students. Despite the educational advantages of graphical programming, TNG has sustained criticism from some who object to the exclusion of a textual ...
Computational and experimental studies of collagen and related diseases
(Massachusetts Institute of Technology, 2005)
Collagen is the most abundant proteins in mammals, and collagen degradation is a process that may be associated with many diseases. In this research we use collagen-like peptides that model both cleavage and noncleavage ...
