Retrieval of cloud-cleared atmospheric temperature profiles from hyperspectral infrared and microwave observations
(Massachusetts Institute of Technology, 2002)
This thesis addresses the problem of retrieving the temperature profile of the Earth's atmosphere from overhead infrared and microwave observations of spectral radiance in cloudy conditions. The contributions of the thesis ...
Automatic syllable detection for vowel landmarks
(Massachusetts Institute of Technology, 2000)
Sociable machines : expressive social exchange between humans and robots
(Massachusetts Institute of Technology, 2000)
Sociable humanoid robots are natural and intuitive for people to communicate with and to teach. We present recent advances in building an autonomous humanoid robot, Kismet, that can engage humans in expressive social ...
Development of X-ray lithography and nanofabrication techniques for III-V optical devices
(Massachusetts Institute of Technology, 2002)
This dissertation covers the development of fabrication techniques for Bragg-grating-based integrated optical devices in III-V materials. Work on this rich family of devices has largely been limited to numerical analysis ...
An estimation-theoretic technique for motion-compensated synthetic-aperture array imaging
(Massachusetts Institute of Technology, 2000)
Synthetic-Aperture Radar (SAR) is an imaging technique that achieves high azimuth resolution by using coherent processing to exploit the relative motion between an airborne or spaceborne radar antenna and the imaged target ...
Real-time spatial-phase-locked electron-beam lithography
(Massachusetts Institute of Technology, 2005)
The ability of electron-beam lithography (EBL) to create sub-10-nm features with arbitrary geometry makes it a critical tool in many important applications in nanoscale science and technology. The conventional EBL system ...
Purely optical tomography : atlas-based reconstruction of brain activation
(Massachusetts Institute of Technology, 2008)
Diffuse Optical Tomography (DOT) is a relatively new method used to image blood volume and oxygen saturation in vivo. Because of its relatively poor spatial resolution (typically no better than 1-2 cm), DOT is increasingly ...
Inferring regulatory networks from multiple sources of genomic data
(Massachusetts Institute of Technology, 2004)
(cont.) algorithm to identify the regulatory models from protein-DNA binding and gene expression data. These models to a large extent agree with the knowledge of gene regulation pertaining to the corresponding regulators. ...
On the capacity of relay networks with finite memory relays
(Massachusetts Institute of Technology, 2004)
(cont.) the length of relay memory and the number of relay stages.
Signal processing in biological cells : proteins, networks, and models
(Massachusetts Institute of Technology, 2005)
This thesis introduces systematic engineering principles to model, at different levels of abstraction the information processing in biological cells in order to understand the algorithms implemented by the signaling pathways ...
