Blue Waters to help researchers tackle Ebola

NCSA’s Blue Waters supercomputer will be used by three research teams to gain new understanding of the deadly Ebola virus, thanks to allocations provided through the National Science Foundation’s Rapid Response Research program. “As the nation’s most powerful and productive supercomputer for open science, Blue Waters plays a vital role in a wide range of research that impacts our lives,” said Blue Waters leader Bill Kramer. “Blue Waters is helping scientists better understand Alzheimer’s disease, HIV, earthquakes, and dangerous tornadoes, and we’re gratified that now we can help address the global threat of Ebola.”.

Using Blue Waters supercomputer to better understand Ebola transmission

Most of us in the United States likely feel safe from Ebola—West Africa feels like it's worlds away. We're located very far geographically from the countries with the highest frequency of infections, like Liberia, Sierra Leone, and Guinea, and many of us aren't likely to be traveling to those places any time soon. But what about in the airports? Could you come into contact with someone who has contracted Ebola and find yourself infected? ... Florida State University professor Ashok Srinivasan is researching a way to prevent that scenario from ever happening, or at least making sure that it is a lot less likely to occur with the help of the Blue Waters supercomputer..

New Boarding Procedures, Smaller Cabin Size May Limit Infection on Planes

During major epidemics, cramped airplane cabins are fertile ground for the spread of infection, but new research suggests changing routine boarding protocols could be a key to reducing rampant transmission of disease. In response to the 2014 Ebola outbreak that grounded hundreds of international flights, Florida State University associate professor of computer science Ashok Srinivasan set out to investigate the mechanics of infection spread on high-occupancy aircraft. ... The team used sophisticated supercomputer simulations to identify air-travel procedures most prone to the spread of infection. Their findings are enough to unnerve frequent fliers: Not only is boarding more dangerous than deplaning in terms of disease transmission, but the three-zone boarding system so commonly used among popular airlines is appreciably worse than the alternatives..

New boarding procedures may limit spread of disease inside airplane cabins

New research out of Florida State University has offered policy makers new strategies for limiting the spread of disease among airline passengers. Computer models suggest revised boarding procedures and the use of smaller plane cabins could reduce the risk of infection during a serious disease outbreak. ... Scientists at Florida State used computer simulations to develop a more pragmatic response. Using current models of human behaviors and the localized spread of disease, researchers designed sophisticated algorithms to predict how different boarding procedures and plane parameters influence the spread of disease inside the tight-quarters of an airplane cabin..

Embry-Riddle researchers study ways to reduce the spread of infectious diseases on commercial airliners

When Embry-Riddle Aeronautical University professor Sirish Namilae travels for pleasure or for work, his eyes are focused on how people are boarding the plane and move through security and other areas of the airport. ... Namilae, the primary author on the two initial research papers that included professors from Arizona State University and Florida State University, studied the transmission of Ebola and other viruses using a multiscale, hybrid computer model. By applying mathematical models used in materials science such as molecular dynamics, passenger movement and boarding and deplaning was analyzed around a hypothetical infected passenger along with transmission rates and incubation periods for diseases..
