Accelerated clustering through locality-sensitive hashing
(Massachusetts Institute of Technology, 2012)
We obtain improved running times for two algorithms for clustering data: the expectation-maximization (EM) algorithm and Lloyd's algorithm. The EM algorithm is a heuristic for finding a mixture of k normal distributions ...
Magnetic properties of an isolated quantum dot
(Massachusetts Institute of Technology, 2003)
A microfabricated solid oxide fuel cell
(Massachusetts Institute of Technology, 2004)
With the ever-increasing ubiquity of mobile consumer electronic devices comes the rising demand for portable electric power. Current battery technology gives a very modest energy return per weight or volume. Hydrocarbons ...
Design and fabrication of sharp bend photonic crystal slab waveguides
(Massachusetts Institute of Technology, 2001)
A periodic arrangement of atoms in a crystal presents a periodic potential for electrons. The bragg diffraction of electrons from the atoms may lead to a band gap, which represents a range of frequencies the electrons ...
Instrumentation and algorithms for electrostatic inverse problems
(Massachusetts Institute of Technology, 2001)
This thesis describes tracking objects with low-level electric fields. A physical model is presented that describes the important interactions and the required mathematical inversions. Sophisticated hardware used to perform ...
Modelling signal interactions with application to financial time series
(Massachusetts Institute of Technology, 2014)
In this thesis, we concern ourselves with the problem of reasoning over a set of objects evolving over time that are coupled through interaction structures that are themselves changing over time. We focus on inferring ...
Cavity filtered injection locking for large angle atomic interferometry
(Massachusetts Institute of Technology, 2000)
PhysioMiner : a scalable cloud based framework for physiological waveform mining
(Massachusetts Institute of Technology, 2014)
This work presents PhysioMiner, a large scale machine learning and analytics framework for physiological waveform mining. It is a scalable and flexible solution for researchers and practitioners to build predictive models ...
Dynamic line integral convolution for visualizing electromagnetic phenomena
(Massachusetts Institute of Technology, 2001)
Vector field visualization is a useful tool in science and engineering, giving us a powerful way of understanding the structure and evolution of the field. A fairly recent technique called Line Integral Convolution (LIC) ...
Quantum Systems Simulator
(Massachusetts Institute of Technology, 2000)
