ITIKI: Bridge between African indigenous knowledge and modern science on drought prediction
(2012)
The now more rampant and severe droughts have become synonymous with Sub-Saharan Africa; they are a major contributor to the acute food insecurity in the Region. Though this scenario may be replicated in other regions in ...
Performance benchmarking physical and virtual linux envrionments
(2012)
Virtualisation is a method of partitioning one physical computer into multiple "virtual" computers, giving each the appearance and capabilities of running on its own dedicated hardware. Each virtual system functions as a ...
Drivable region detection for autonomous robots applied to South African underground mining
(2012)
This dissertation focuses on enhancing autonomous robots' capability to identify drivable regions in underground terrains. A system model that compares the drivability analysis of underground terrains using the entropy ...
A Lossy, Synchronization-Free, Race-Full, But Still Acceptably Accurate Parallel Space-Subdivision Tree Construction Algorithm
(2012-02-23)
We present a new synchronization-free space-subdivision tree construction algorithm. Despite data races, this algorithm produces trees that are consistent enough for the client Barnes-Hut center of mass and force computation ...
GURLS: a Toolbox for Regularized Least Squares Learning
(MIT CSAIL, 2012-01-31)
We present GURLS, a toolbox for supervised learning based on the regularized least squares algorithm. The toolbox takes advantage of all the favorable properties of least squares and is tailored to deal in particular with ...
DSENT - A Tool Connecting Emerging Photonics with Electronics for Opto-Electronic Networks-on-Chip Modeling
(2012-02-08)
With the advent of many-core chips that place substantial demand on the NoC, photonics has been investigated as a promising alternative to electrical NoCs. While numerous opto-electronic NoCs have been proposed, their ...
A Method for Fast, High-Precision Characterization of Synthetic Biology Devices
(2012-04-07)
Engineering biological systems with predictable behavior is a foundational goal of synthetic biology. To accomplish this, it is important to accurately characterize the behavior of biological devices. Prior characterization ...
Temporally Scalable Visual SLAM using a Reduced Pose Graph
(2012-05-25)
In this paper, we demonstrate a system for temporally scalable visual SLAM using a reduced pose graph representation. Unlike previous visual SLAM approaches that use keyframes, our approach continually uses new measurements ...
A Case for Fine-Grain Adaptive Cache Coherence
(2012-05-22)
As transistor density continues to grow geometrically, processor manufacturers are already able to place a hundred cores on a chip (e.g., Tilera TILE-Gx 100), with massive multicore chips on the horizon. Programmers now ...
Optimal Parametric Auctions
(2012-05-08)
We study the problem of profit maximization in auctions of one good where the buyers' valuations are drawn from independent distributions. When these distributions are known to the seller, Myerson's optimal auction is a ...
