Yellowstone super-eruption would send ash across North America

August 27, 2014 12:22 pm | News | Comments

According to a new study, in the unlikely event of a volcanic super-eruption at Yellowstone National Park, the northern Rocky Mountains would be blanketed in meters of ash, and millimeters would be deposited as far away as New York City, Los Angeles and Miami. An improved computer model finds that the hypothetical, large eruption would create a distinctive kind of ash cloud known as an umbrella, which expands evenly in all directions.

Saving seeds the right way can save the world’s plants

July 30, 2014 11:50 am | News | Comments

For decades, strategic seed collections that help preserve biodiversity have been guided by simple models that offer a one-size-fits-all approach for how many seeds to gather. A new study, however, has found that more careful tailoring of seed collections to specific species and situations is critical to preserving plant diversity. A new approach called simulation-based planning was used to recommend how seeds are saved and reintroduced.

Familiar yet strange: Water’s “split personality” revealed by computer model

June 18, 2014 2:01 pm | by Catherine Zandonella, Office of the Dean for Research | News | Comments

Seemingly ordinary, water has quite puzzling behavior. Why, for example, does ice float when most liquids crystallize into dense solids that sink? Using a computer model to explore water as it freezes, a team at Princeton Univ. has found that water's weird behaviors may arise from a sort of split personality: At very cold temperatures and above a certain pressure, water may spontaneously split into two liquid forms.

Retaining Knowledge After an Engineer Leaves

June 4, 2014 11:31 am | by Paul Goossens, VP of Engineering Solutions, Maplesoft | Articles | Comments

If a senior engineer left an organization suddenly, how many hours would it take for the engineering team to take over his projects, confident that they understand not only the designs, but why those designs are the way they are? The typical answer is “far too many”. Widespread use of CAE and data management tools have made this task much easier than before, but these tools do little to record the thinking behind the results.
