A peer-to-peer anonymizing network layer
(Massachusetts Institute of Technology, 2002)
Coding in the fusiform face area of the human brain
(Massachusetts Institute of Technology, 2003)
Synchronization on nulticore architectures
(Massachusetts Institute of Technology, 2014)
The rise of multicore computing has made synchronization necessary to overcome the challenge of sharing data between multiple threads. Locks are critical synchronization primitives for maintaining data integrity and ...
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 ...
Rendering from unstructured collections of images
(Massachusetts Institute of Technology, 2002)
Computer graphics researchers recently have turned to image-based rendering to achieve the goal of photorealistic graphics. Instead of constructing a scene with millions of polygons, the scene is represented by a collection ...
Modelling out-of-vocabulary words for robust speech recognition
(Massachusetts Institute of Technology, 2002)
This thesis concerns the problem of unknown or out-of-vocabulary (OOV) words in continuous speech recognition. Most of today's state-of-the-art speech recognition systems can recognize only words that belong to some ...
The development of components for ultrafast all-optical communication networks
(Massachusetts Institute of Technology, 2000)
The need for ultrafast (greater than 100 Gbps) all-optical communication networks is amplified as the amount of data-containing communication traffic continues to grow at an exorbitant rate. Multiplexing schemes are ...
Measuring the performance of a Distributed Quota Enforcement system for spam control
(Massachusetts Institute of Technology, 2006)
In this thesis, I evaluate Distributed Quota Enforcement (DQE), a system for enforcing quotas on e-mail use as a spam control mechanism. I briefly describe the design and implementation of DQE, and then evaluate the ...
Riffle : an efficient communication system with strong anonymity
(Massachusetts Institute of Technology, 2015)
Anonymous communication is an important part of democratic societies and freedom of speech. Whistleblowers, protest organizers, and, more broadly, anyone with controversial viewpoints have been using the limited form of ...
Spoken language understanding in a nutrition dialogue system
(Massachusetts Institute of Technology, 2015)
Existing approaches for the prevention and treatment of obesity are hampered by the lack of accurate, low-burden methods for self-assessment of food intake, especially for hard-to-reach, low-literate populations. For this ...
