Capacity provisioning, failure recovery and throughput analysis for low earth orbit satellite constellations
(Massachusetts Institute of Technology, 2002)
We investigate the capacity needed to build a restorable satellite network and design routing schemes to achieve high throughput. Specifically, the first part of this thesis considers the link capacity requirement for a ...
Quantum signal processing
(Massachusetts Institute of Technology, 2002)
Quantum signal processing (QSP) as formulated in this thesis, borrows from the formalism and principles of quantum mechanics and some of its interesting axioms and constraints, leading to a novel paradigm for signal ...
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 ...
Quantum error modelling and correction in long distance teleportation using singlet states
(Massachusetts Institute of Technology, 2002)
Fabrication of a planar optical add/drop channel filter in silicon oxynitride
(Massachusetts Institute of Technology, 2002)
A peer-to-peer anonymizing network layer
(Massachusetts Institute of Technology, 2002)
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 ...
Parallelizing the GSM speech compression algorithm on Raw
(Massachusetts Institute of Technology, 2002)
The GSM speech encoding algorithm, a widely used compression algorithm in mobile communications, was parallelized on Raw, a highly distributed hardware architecture with low latency communication. Parallelization architectures ...
