Carbon, carbon everywhere, but not from the Big Bang

  • PDF
TechAndComputer (May 11, 2011) — As Star Trek is so fond of reminding us, we're carbon-based life forms. But the event that jump-started the universe, the Big Bang, didn't actually produce any carbon, so where the heck did it -- and we -- come from? An NC State researcher has helped create supercomputer simulations that demonstrate how carbon is produced in stars, proving an old theory correct.

More than 50 years ago, an astronomer named Fred...

Razing Seattle's viaduct doesn’t guarantee nightmare commutes, model says

  • PDF
TechAndComputer (May 10, 2011) — Debate about how to replace Seattle's deteriorating waterfront highway has centered on uncertainties in the project's price tag. Drilling a deep-bore tunnel and building an underground highway is estimated to cost around $4 billion, but some worry the final price could be higher, as it was for Boston's infamous Big Dig.

University of Washington statisticians have, for the first time, explored a different subject...

Blueprint of a trend: How does a financial bubble burst?

  • PDF
TechAndComputer (May 2, 2011) — A joint study by academics in Switzerland, Germany and at Boston University sheds new light on the formation of financial bubbles and crashes. Wild fluctuations in stock prices caused by bubbles bursting have had a dramatic impact on the world economy and the personal fortunes of millions of us in the last few years.

The study will be published in the Proceedings of the National Academy of Sciences on May 10 and...

Migratory birds, domestic poultry and avian influenza

  • PDF
TechAndComputer (Apr. 5, 2011) — The persistence and recurrence of H5N1 avian influenza in endemic regions can largely be blamed on movement and infection by migratory birds. Trade in poultry, poultry products and caged birds, and movement of wild birds also account for H5N1 prevalence in these areas. Several recent outbreaks of avian influenza have suggested strong evidence of migratory birds playing a role in transmitting the virus over long...

Gaming, simulation tools merged to create models for border security

  • PDF
TechAndComputer (May 11, 2011) — With funding from the Department of Homeland Security's Customs and Border Protection (CBP), researchers at Sandia National Laboratories have developed a high-fidelity simulation and analysis program that aids policy and decision-makers tasked with making key procurements and funding choices.

The Borders High Level Model (HLM) uses a serious gaming platform known as Ground Truth, a force-on-force battle simulation...
