Motifs, binding, and expression : computational studies of transcriptional regulation
(Massachusetts Institute of Technology, 2009)
Organisms must control gene expression in response to developmental, nutritional, or other environmental cues. This process is known as transcriptional regulation and occurs through complex networks of proteins interacting ...
The perception of material qualities in real-world images
(Massachusetts Institute of Technology, 2009)
One can easily tell if a sidewalk is slippery, if food is fresh, if a spoon is made of plastic or stainless steel, or if a suspicious looking mole warrants a trip to the doctor. This ability to visually identify and ...
Novel broadband light sources and pulse generation techniques at 1.5 [mu]m
(Massachusetts Institute of Technology, 2009)
A wide diversity of applications, in both fundamental science and practical technology, has come to rely on broadband optical light sources as key enabling tools. In this thesis, we investigate three devices that contribute ...
Low-cost, highly efficient, and tunable ultrafast laser technology based on directly diode-pumped Cr:Colquiriites
(Massachusetts Institute of Technology, 2010)
This doctoral project aims to develop robust, ultra low-cost ($5,000-20,000), highly-efficient, and tunable femtosecond laser technology based on diode-pumped Cr:Colquiriite gain media (Cr:LiCAF, Cr3+:LiSAF and Cr:LiSGaF). ...
Advanced nonintrusive load monitoring system
(Massachusetts Institute of Technology, 2011)
There is a need for flexible, inexpensive metering technologies that can be deployed in many different monitoring scenarios. Individual loads may be expected to compute information about their power consumption. Utility ...
Tactual display of consonant voicing to supplement lipreading
(Massachusetts Institute of Technology, 2003)
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 ...
Robust PCPs of proximity and shorter PCPs
(Massachusetts Institute of Technology, 2004)
Observer-based monitors and distributed wave controllers for electromechanical disturbances in power systems
(Massachusetts Institute of Technology, 2004)
Detection of consonant voicing : a module for a hierarchical speech recognition system
(Massachusetts Institute of Technology, 1999)
In this thesis, a method for designing a hierarchical speech recognition system at the phonetic level is presented. The system employs various component modules to detect acoustic cues in the signal. These acoustic cues ...
Providing QoS guarantees in input buffered crossbar switches with speedup
(Massachusetts Institute of Technology, 1998)
This dissertation investigates a number of issues related to providing Quality of Service guarantees in input-buffered crossbar switches with speedup. It is shown that speedup of 4 is sufficient to ensure 100% asymptotic ...
