A single-pass grid-based algorithm for clustering big data on spatial databases
(Massachusetts Institute of Technology, 2017)
The problem of clustering multi-dimensional data has been well researched in the scientific community. It is a problem with wide scope and applications. With the rapid growth of very large databases, traditional clustering ...
Squadbox : a tool to combat email harassment using friendsourced moderation
(Massachusetts Institute of Technology, 2017)
Online harassment is both a social and technical problem, and has yet to be successfully solved. In order to better understand the issue and the challenges surrounding it, we conducted interviews with eighteen recipients ...
Capturing the human figure through a wall
(Massachusetts Institute of Technology, 2017)
We present RF-Capture, a system that captures the human figure - i.e., a coarse skeleton - through a wall. RF-Capture tracks the 3D positions of a person's limbs and body parts even when the person is fully occluded from ...
Dynamic, personalized discrete choice incentive allocation to optimize system performance
(Massachusetts Institute of Technology, 2017)
Incentivization is a powerful way to get independent agents to make choices that drive a system to a desired optimum. Simply offering compensation for making a certain choice is enough to change the behavior of some people. ...
AdaptDB : adaptive partitioning for distributed joins
(Massachusetts Institute of Technology, 2017)
Big data analytics often involves complex join queries over two or more tables. Such join processing is expensive in a distributed setting both because large amounts of data must be read from disk, and because of data ...
Recognition of 3D compressed images and its traffic monitoring applications
(Massachusetts Institute of Technology, 2004)
The need for improved security requires the development of better monitoring systems. These systems must manage large numbers of images sent over communication networks. For example, a high transmission load results when ...
Design automation and analysis of three-dimensional integrated circuits
(Massachusetts Institute of Technology, 2004)
This dissertation concerns the design of circuits and systems for an emerging technology known as three-dimensional integration. By stacking individual components, dice, or whole wafers using a high-density electromechanical ...
The development of novel passive and active photonic-crystal devices
(Massachusetts Institute of Technology, 2004)
Photonic crystals are anticipated to have impact on large-scale photonic integrated circuits by allowing the creation of compact and efficient devices such as waveguides, splitters, microcavity filters, light emitting ...
Thermoelectric properties of Bi₁â‚‹x̳Sbx̳ nanowires and lead salt superlattice nanowires
(Massachusetts Institute of Technology, 2003)
This thesis involves an extensive experimental and theoretical study of the thermoelectric-related transport properties of BilxSbx nanowires, and presents a theoretical framework for predicting the electrical properties ...
Distributed optimization and market analysis of networked systems
(Massachusetts Institute of Technology, 2014)
In the interconnected world of today, large-scale multi-agent networked systems are ubiquitous. This thesis studies two classes of multi-agent systems, where each agent has local information and a local objective function. ...
