Evolving language among agents
(Massachusetts Institute of Technology, 1999)
A peer-to-peer anonymizing network layer
(Massachusetts Institute of Technology, 2002)
Measuring the performance of a Distributed Quota Enforcement system for spam control
(Massachusetts Institute of Technology, 2006)
In this thesis, I evaluate Distributed Quota Enforcement (DQE), a system for enforcing quotas on e-mail use as a spam control mechanism. I briefly describe the design and implementation of DQE, and then evaluate the ...
Efficient, low-distortion switch-mode power amplifier for amplitude modulation
(Massachusetts Institute of Technology, 2011)
Amplitude modulation systems are used in many areas of engineering, especially communication based disciplines. Typical systems have low-level signals which encode the desired information to be transmitted. These low-level ...
Interactive spectral analysis learning module
(Massachusetts Institute of Technology, 2001)
Due to increased demand for interactive learning opportunities for engineering students, an interactive spectral analysis learning module was developed for the course Biomedical Signal and Image Processing (HST582J/6.555 ...
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 ...
Distributed data as a choice in PetaBricks
(Massachusetts Institute of Technology, 2012)
Traditionally, programming for large computer systems requires programmers to hand place the data and computation across all system components such as memory, processors, and GPUs. As each system can have sufficiently ...
The stochastic air traffic flow management rerouting problem
(Massachusetts Institute of Technology, 2004)
We formulate a model for planning the rerouting of aircraft to alleviate en-route congestion, with system capacity being modeled stochastically. To overcome problems with tractability, we apply a Dantzig-Wolfe decomposition ...
Biologically-plausible six-legged running : control and simulation
(Massachusetts Institute of Technology, 2003)
This thesis presents a controller which produces a stable, dynamic 1.4 meter per second run in a simulated twelve degree of freedom six-legged robot. The algorithm is relatively simple; it consists of only a few hand-tuned ...
Solving hybrid decision-control problems through conflict-directed branch & bound
(Massachusetts Institute of Technology, 2004)
There exists a large class of problems that incorporate both logical decision and algebraic constraints. For example, in cooperative path planning (CPP) problem, obstacle avoidance can be achieved by selecting a direction ...
