A Heterogeneous Compute Solution For Optimized Genomic Selection Analysis, Trevor Devore, Scott Kenneth Winkleblack, Bruce Golden, Chris Lupo
A Heterogeneous Compute Solution For Optimized Genomic Selection Analysis, Trevor Devore, Scott Kenneth Winkleblack, Bruce Golden, Chris Lupo
Computer Science and Software Engineering
This paper presents a heterogeneous computing solution for an optimized genetic selection analysis tool, GenSel. GenSel can be used to efficiently infer the effects of genetic markers on a desired trait or to determine the genomic estimated breeding values (GEBV) of genotyped individuals. To predict which genetic markers are informational, GenSel performs Bayesian inference using Gibbs sampling, a Markov Chain Monte Carlo (MCMC) algorithm. Parallelizing this algorithm proves to be a technically challenging problem because there exists a loop carried dependence between each iteration of the Markov chain. The approach presented in this paper exploits both task-level parallelism (TLP) and …
Is There Progress Toward Sustainability?: Despite The Inherent Human Resistance To Change., Jens Pohl
Is There Progress Toward Sustainability?: Despite The Inherent Human Resistance To Change., Jens Pohl
Collaborative Agent Design (CAD) Research Center
The theme of this paper is to briefly survey the status of current efforts to maintain our natural environment and then discuss prospects for achieving future sustainability. The author finds that while there has been general recognition of the need for environmental sensitivity and conservation of natural resources, progress toward achieving sustainability goals has been slow. A principal reason for this lack of action is found in the reactive nature of the human species. Situated by biological design in our environment we typically respond to environmental changes only after they have occurred. Accordingly, while a number of revolutionary proposals have …

Using Remote Sensing Data To Predict The Spread Of Mosquito Borne Disease, Mary Ellen O'Donnell, Erika Podest
STAR Program Research Presentations
There is interest in how environmental variables derived from satellite data such as temperature, vegetation cover, and precipitation correlate to vector borne disease occurrence such as malaria and dengue fever. This study will be carried out using a decision tree based open source software called Random Forests to find correlations between the remote sensing variables and mosquito abundance. Software will be written in C# to take large amounts of data from the NASA satellite database and automatically format it for the Random Forest Software input. Correlations found, using Random Forests, between disease incidence and the variables can be used as …

Exploring Abstract Interfaces In System-On-Chip Integration, Andrew Danowitz
Computer Science and Software Engineering
Modern mobile devices are marvels of computation. They can encode high defnition video, processing and compressing over 350MB/s of image data in real time. They have no trouble driving displays with as much resolution as a full laptop, and smartphone manufacturers boast of running games with "console quality" graphics. Mobile devices pack all of this computational power into a 12\ handheld package by integrating a number of specialized hardware accelerators (IP) along with conventional CPU and GPUs in a system on chip (SoC). Unfortunately, creating these specialized systems is becoming increasingly expensive. Since hardware accelerators come from a number of …
Creating A Phrase Similarity Graph From Wikipedia, Lubomir Stanchev
Creating A Phrase Similarity Graph From Wikipedia, Lubomir Stanchev
Computer Science and Software Engineering
The paper addresses the problem of modeling the relationship between phrases in English using a similarity graph. The mathematical model stores data about the strength of the relationship between phrases expressed as a decimal number. Both structured data from Wikipedia, such as that the Wikipedia page with title “Dog” belongs to theWikipedia category “Domesticated animals”, and textual descriptions, such as that the Wikipedia page with title “Dog” contains the word “wolf” thirty one times are used in creating the graph. The quality of the graph data is validated by comparing the similarity of pairs of phrases using our software that …
Twill: A Hybrid Microcontroller-Fpga Framework For Parallelizing Single-Threaded C Programs, Douglas S. Gallatin, Aaron Keen, Chris Lupo, John Y. Oliver
Twill: A Hybrid Microcontroller-Fpga Framework For Parallelizing Single-Threaded C Programs, Douglas S. Gallatin, Aaron Keen, Chris Lupo, John Y. Oliver
Computer Science and Software Engineering
Increasingly System-On-A-Chip platforms which incorporate both microprocessors and re-programmable logic are being utilized across several fields ranging from the automotive industry to network infrastructure. Unfortunately, the development tools accompanying these products leave much to be desired, requiring knowledge of both traditional embedded systems languages like C and hardware description languages like Verilog. We propose to bridge this gap with Twill, a truly automatic hybrid compiler that can take advantage of the parallelism inherent in these platforms. Twill can extract long-running threads from single threaded C code and distribute these threads across the hardware and software domains to more fully utilize …

The Bonneville Power Administration (BPA) employs Phasor Measurement Units (PMUs) to measure variables such as Voltage, Frequency, and Phasor Angles every sixtieth of a second. These measurements result in terabytes of data which are analyzed to detect abnormalities in the power grid. Recently BPA has switched the data file format from DST to PDAT. A function does not currently exist to read in PDAT files in order to prepare the data for analysis. In order to do this the raw PMU data must be sorted and extracted to ensure its accuracy prior to analysis. This research worked to produce a …

Updating And Revising Star Camera For Future Flights Of Balloon Borne Experiment, Krystle N. Sy, Seth Hillbrand
STAR Program Research Presentations
The BLAST (Balloon-borne Large Aperture Submillimeter Telescope) experiment surveys the galaxy from altitudes of 100,000 ft in order to answer important cosmological questions, such as how stars are formed. This experiment is conducted above Antarctica to minimize unwanted noise. Two star cameras are used in the navigation systems to identify known stars. The cameras take pictures and match stars in the image to known star positions from a catalog stored in the star camera's computer. This is done using code written in C++, a computer programming language. In order to modernize the system, the code needs to be updated. A …

Chapter 20 The Hybrid Course: Facilitating Learning Through Social Interaction Technologies, Lorraine D. Jackson, Joe Grimes
Computer Science and Software Engineering
This chapter surveys the benefits and challenges of hybrid courses, which blend face-to-face instruction with online learning, and opportunities provided by the introduction of Web-based social interaction technologies. It discusses the pedagogical implications of various Web 2.0 tools: that is, asynchronous discussion boards, blogs, wikis, podcasts, RSS, e-portfolios, folksonomies, educational gaming, data mashups, and simulations. The authors argue that as hybrid courses continue to evolve to meet the needs of students, instructors, and institutions of higher learning, the integration of Web 2.0 applications in a hybrid model requires thoughtful course design, clear educational objectives, and carefully planned activities.
