Low-latency network coding for streaming video multicast
(Massachusetts Institute of Technology, 2008)
Network coding has been successfully employed to increase throughput for data transfers. However, coding inherently introduces packet inter-dependencies and adds decoding delays which increase latency. This makes it difficult ...
Stereo vision and mapping with unsynchronized cameras
(Massachusetts Institute of Technology, 2008)
Environmental awareness is an important prerequisite for autonomous behavior in vehicles. Without it, robots are unable to react to unknown surroundings and require extensive human input for tasks such as target identification ...
Nodal photolithography : lithography via far-field optical nodes in the resist
(Massachusetts Institute of Technology, 2008)
In this thesis, I investigate one approach - stimulated emission depletion - to surmounting the diffraction limitation of optical lithography. This approach uses farfield optical nodes to orchestrate reversible, saturable ...
Quantitative analysis of cerebral white matter anatomy from diffusion MRI
(Massachusetts Institute of Technology, 2008)
In this thesis we develop algorithms for quantitative analysis of white matter fiber tracts from diffusion MRI. The presented methods enable us to look at the variation of a diffusion measure along a fiber tract in a single ...
Ultrafast sources of entangled photons for quantum information processing
(Massachusetts Institute of Technology, 2008)
Recent advances in quantum information processing (QIP) have enabled practical applications of quantum mechanics in various fields such as cryptography, computation, and metrology. Most of these applications use photons ...
Fast methods for inverse wave scattering problems
(Massachusetts Institute of Technology, 2008)
Inverse wave scattering problems arise in many applications including computerized/diffraction tomography, seismology, diffraction/holographic grating design, object identification from radar singals, and semiconductor ...
Evolutionary approaches toward practical network coding
(Massachusetts Institute of Technology, 2008)
There have been numerous studies showing various benefits of network coding. However, in order to have network coding widely deployed in real networks, it is also important to show that the amount of overhead incurred by ...
Micro-cleaved ridge lasers for optoelectronic integration on silicon
(Massachusetts Institute of Technology, 2008)
This thesis addresses one of the last hurdles to optoelectronic integration on silicon, namely the incorporation of room-temperature, electrically-pumped edge-emitting laser diodes. To this end, thin (-6 pm) InP-based ...
Joint base-calling of two DNA sequences with factor graphs
(Massachusetts Institute of Technology, 2008)
The advent of DNA sequencing has revolutionized biological research by providing virtual blueprints of living organisms and offering insights into complicated biochemical processes. DNA sequencing is a process encompassing ...
BlendDB : blending table layouts to support efficient browsing of relational databases
(Massachusetts Institute of Technology, 2008)
The physical implementation of most relational databases follows their logical description, where each relation is stored in its own file or collection of files on disk. Such an implementation is good for queries that ...
