Game Changer Research Aims to Forecast Tornadoes

Dr. Amy McGovern

From an article on Science Nation:


 "Tornadoes claim hundreds of lives and cause billions of dollars in damages in the United States. But the tornado outbreak across the South on April 27, 2011, was startling, even for veteran forecasters such as Greg Carbin at the National Oceanic and Atmospheric Administration (NOAA) Storm Prediction Center (SPC) in Norman, Okla.
"Through the 24-hour loop here, almost 200 tornadoes had occurred in that period of time and, unfortunately, over 315 fatalities. Primarily Alabama was hit hardest but also fatalities in Tennessee, Georgia, Mississippi, and Virginia for this event," says Carbin.
As the warning coordination meteorologist at SPC, he would like to see tools that could help predict these killer storms." 



Dr. McGovern and her team of researchers are working to develop the tools necessary to predict these storms.  Read the full story here...

Title: 
NeTS: Small: Collaborative Research: Cross Layer Survivability to Cascading Failures in Layered Networks

ABSTRACT:

The objective of this research is to carry out a novel study of network survivability across layers to deal with cascading failures in layered networks. This research will be in the context of IP-over-WDM optical networks, with a focus on multiple failures in the physical (optical) layer and their consequences at the higher layer, namely the IP layer.  Specifically, the broad scope of the project covers i) Survivable logical topology mapping under multiple failures, ii) Logical topology mapping for guaranteed survivability, iii) Logical topology mapping under multiple constraints, and iv) A generalized theory of flows across layers, capacity of survivable logical topologies and related algorithmic challenges.

The intellectual merits of the proposed research lie in developing unifying theories and methodologies that will make significant advances to the understanding of cross-layer survivability issues, and providing the theoretical foundation for future advances in the general area of cross-layer design and optimization.  The research team will build these theories on modern advances in graph theory, mathematical programming and algorithm design. Innovative algorithmic techniques based on advanced data structures and computer algorithms such as approximation techniques will be developed. A generalized theory of cross layer flows that will go well beyond the widely used classical theory of single layer flows will be developed.

Besides the above intellectual merits, the research also has several broader impacts. WDM Optical networks form the critical backbone of all modern communication networks and systems. Modern communication systems consist of multiple physical implementations communicating via layered protocols. As such, a single failure at one layer may lead to cascading failures, i.e., failures at the physical layer lead to failures at the logical layer. Research in this area of cross-layer survivability is still in its infancy. Though IP-Over-WDM networks will provide the context for this research, the theory of cross layer flows and the algorithmic (in particular approximation) techniques that will be developed will have multidisciplinary value spanning several STEM related areas: computer science, electrical engineering, graph theory, mathematical programming, and the emerging area of network science.  Besides extending the frontiers of knowledge in cross layer theory, the research will have significant educational value in training highly skilled researchers for research and development in cutting edge technologies in different areas of information technology. The training program will have a specific focus on training undergraduate students for future leadership in STEM areas.

Title: The Privilege of Student, Experiential Learning, Engineering Competition Teams (SELECT)
Agency: National Science Foundation
Start Date: Sept 15, 2011
End Date: August 31, 2015

Layman Abstract:
Student, Experiential Learning, Engineering Competition Teams (SELECT) are displayed as the hallmark of engineering programs and are commonly featured in materials shared with prospective students and donors. SELECT provide an opportunity for engineering students to practice engineering technical and professional skills while engaged in competitive, experiential learning, design/build projects. In spite of efforts to increase participation of under-represented populations (URP) in engineering programs, participation rates of URP students in many competition teams are exceptionally low, even when normalized for engineering enrollment. The research literature investigating student competition teams includes only a few papers founded on a research design including a research question, data collection and structured analysis, with only one investigating URP participation from a gender perspective, and none exploring other dimensions of diversity. This paucity is in stark contrast to the wealth of well-structured research examinations of curricular-based team work, although considerations of race/ethnicity and gender are generally absent here as well. The Research Institute for STEM Education will build on a history of qualitative research, supplemented with quantitative data, identifying factors contributing to equity and broadening participation in engineering by addressing the research question: What factors contribute to cultures of inclusion or exclusion within Student, Experiential Learning, Engineering Competition Teams (SELECT)?

University of Oklahoma Researchers use NICS to Detail the Inner Workings of Tornadoes

Dr. Amy McGovern

From an article on NICS:

 "Just last month, in a span of 24 hours beginning on April 27th, the southeastern United States saw a rare outbreak of tornadoes which resulted in a combined 344 deaths, according to estimates by the National Weather Service and the National Oceanic and Atmospheric Administration. Not since 1936 have more people been killed in a two-day period due to tornadoes. And that’s not to mention the likely billions of dollars in property damage.
Despite their prevalence in this country, however, and especially in the central United States in an area known as “tornado alley,” there is still much we don’t know about these much-feared funnels from the sky." 


Dr. McGovern and her team of researchers are attempting to unravel some of those inner-workings.  Read the full story here... Recently a new article covering Dr. McGovern's research on using simulations to predict tornadoes was posted here...
