The raw router : gigabit routing on a general-purpose microprocessor
(Massachusetts Institute of Technology, 2004)
Conventionally, high-speed routers are built using custom hardware, typically dubbed as network processors. A prominent example of such a network processor is the Intel IXP1200. Such a network processor typically takes ...
A programming environment for on-demand service overlays
(Massachusetts Institute of Technology, 2004)
Recent years have seen a growing interest in overlay networks. Overlay networks simplify the complications of creating and connecting distributed applications on the network by optimizing the underlying IP routing architecture. ...
Articulatory features for robust visual speech recognition
(Massachusetts Institute of Technology, 2004)
This thesis explores a novel approach to visual speech modeling. Visual speech, or a sequence of images of the speaker's face, is traditionally viewed as a single stream of contiguous units, each corresponding to a phonetic ...
Fabrication and testing of an infrared spectral control component for thermophotovoltaic power conversion applications
(Massachusetts Institute of Technology, 2004)
Thermophotovoltaic (TPV) power conversion is the direct conversion of thermal radiation to electricity. Conceptually, TPV power conversion is a very elegant means of energy conversion. A thermal source emits a radiative ...
On the relationship between carrier mobility and velocity in sub-50 mm MOSFETs via calibrated Monte Carlo simulation
(Massachusetts Institute of Technology, 2004)
Subsequent to accurate 2D inverse modeling in the regime sensitive to electrostatics of industrial sub-50 nm NMOSFETs, a 2D full-band Monte Carlo device simulator was calibrated in the regime sensitive to transport parameters. ...
Formulating earthquake response modes in Iran
(Massachusetts Institute of Technology, 2004)
The objective of this paper was to try and find the optimal distribution of rescuers after an earthquake with a very large magnitude caused major damage in two different cities. A model was developed to optimally divide ...
Matching and compressing sequences of visual hulls
(Massachusetts Institute of Technology, 2004)
In this thesis, we implement the polyhedral visual hull (PVH) algorithm in a modular software system to reconstruct 3D meshes from 2D images and camera poses. We also introduce the new idea of visual hull graphs. For data, ...
Delay improvements from multiple wavelengths in an optical folded bus
(Massachusetts Institute of Technology, 2004)
In this thesis, we compared the delay of a single wavelength local area optical network and a multiple wavelength local area optical network. We used an optical folded bus as the architecture for the LAN and analyzed the ...
The use of ultrasound to facilitate the delivery of genetic-based therapeutic strategies
(Massachusetts Institute of Technology, 2004)
(cont.) preliminary experiments will eventually lead to a clinical methodology where ultrasound-enhanced gene therapy transfection would be followed with ultrasound-directed spatial control of gene expression.
A Lorentz-force actuated controllable needle-free drug delivery system
(Massachusetts Institute of Technology, 2004)
The advantages of delivering injections via needle-free methods are numerous. However, conventional methods for needle-free injection lack sufficient control over depth of penetration and shape of injection. Thus, a ...
