List decoding of error-correcting codes
(Massachusetts Institute of Technology, 2001)
Error-correcting codes are combinatorial objects designed to cope with the problem of reliable transmission of information on a noisy channel. A fundamental algorithmic challenge in coding theory and practice is to efficiently ...
Coupled modes analysis of SRS backscattering, with Langmuir decay and possible cascadings
(Massachusetts Institute of Technology, 2002)
Recent experiments aimed at understanding stimulated Raman scattering (SRS) in ICF laser-plasma interactions, suggest that SRS is coupled to the Langmuir decay interaction (LDI). The effects of LDI on the saturation of the ...
Design, development and characterization of an integrated multispectral polarimetric sensor system
(Massachusetts Institute of Technology, 2001)
In this thesis, a new type of integrated imaging sensor is introduced to detect multispectral and polarimetric signatures in an infrared scene. The sensor is a stack consisting of an infrared detector array, and an array ...
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 ...
Development of terahertz quantum-cascade lasers
(Massachusetts Institute of Technology, 2007)
The terahertz or the far-infrared frequency range of the electromagnetic spectrum ( ... ) has historically been technologically underdeveloped despite having many potential applications, primarily due to lack of suitable ...
Automating the construction of a complier heuristics using machine learning
(Massachusetts Institute of Technology, 2006)
Compiler writers are expected to create effective and inexpensive solutions to NP-hard problems such as instruction scheduling and register allocation. To make matters worse, separate optimization phases have strong ...
Long-term robot mapping in dynamic environments
(Massachusetts Institute of Technology, 2011)
One of the central goals in mobile robotics is to develop a mobile robot that can construct a map of an initially unknown dynamic environment. This is often referred to as the Simultaneous Localization and Mapping (SLAM) ...
Performance evaluation and optimization models for processing networks with queue-dependent production quantities
(Massachusetts Institute of Technology, 2000)
