Generating topic detection training corpora from...
Fall 2006 with Chris Harman. Advisor: Rich Wicentowski
This project focused on generating training/testing documents (corpora, for those in the know) for automated tagging using the social bookmarking site del.icio.us.
Social bookmarking sites provide a wealth of heavily cross-referenced tagging data. However, only a very particular subset of the Web gets added to these sites. So our...

Parallel interpolation of elevation grids
Fall 2006 with Scott Blaha. Advisor: Andy Danner
Real life geographic elevation data comes in three-dimensional point clouds, meaning data is not aligned along a grid or even has uniform distribution. Geographic Information Systems take elevation grids for most processing tasks (viewshed computation, watershed computation, flow routing etc.). The natural way of getting grids from point clouds is...

Audit logs for computer security monitoring
Summer ‘05 with Ben Kuperman
During an undergraduate research fellowship at Swarthmore College I worked with Professor Kuperman on expanding a preliminary system written for Sun Solaris. We first ported it over to Debian Linux. Afterwards, I redesigned and reimplemented the log recording mechanism with easily synchronizable log entry commit semantics, and wrote a highly modular log...

Integrating Moodle with Marratech Video...
Summer ‘06 at Southwestern University for NITLE
This work was done with a team of nine other undergraduates. We wrote a module for the Moodle Course Management System that interfaces with the Marratech Video Conferencing Suite to allow seamless video conferencing from within moodle. This project involved Java EE programming on the Marratech side and PHP and MySQL on the Moodle side.

Distributed execution systems: to centralize or...
Spring ‘06 with Javier Prado. Advisor: Tia Newhall
We wrote two distributed execution systems, one centralized and one decentralized. We tested the performance of these systems under different experimentally induced conditions.

The ultimate RISC computer
Spring ‘05 with Adem Kader. Advisor: Bruce Maxwell
We wrote a One Instruction Set Computer in VHDL and developed a simple assembly language for it with a virtual machine and an assembler written in Java 5. Adem keeps the final write-up on his site. Documentation for the compiler and virtual machine generated with Javadoc can be found here.
