When you can't quite get the angle, take hands-free selfies with the Samsung Galaxy Z Flip 5,

stand it up, step back, and your photos are also synced to your Chromebook, ready to edit.

This is CBSI in the world. I'm John Vatservici,

a professor of Hussam, Mahmoud, Colorado State University,

who, with his colleagues, have developed a model for communities to anticipate what would happen

if a wildfire breaches from the forest into the town. Mahmoud Hussam, what you said,

was most inviting to me because I've seen overviews of Maui, and it's like a tornado.

It comes through the community on one side is burned, and the other side is not.

Is that a way to talk about how fires act, and you go back, and you look at the

house that burned, and you look at the didn't, and you look at the wind conditions?

Is that what you're doing? Yeah, exactly. Of course, if the problem was easy, John,

we would have solved it by we, I mean the entire community by now. It's not easy.

So it's not intuitive for you to look at a burned community and think, why did it burn this way?

We can, people who have experience, can kind of get an idea, this must have been the wind

direction, or this must have been why did that, but it's really very difficult to tell.

So the model we have, we're able to actually provide information on the location of every building,

the location of vegetation, the type of materials used in the buildings, the type of vegetation,

and then we overlay on top of the wind speed and direction, and then the model calculates

two different physics-based fire propagation mechanisms, including something called

the radiation and convection, and the embers where they land, we're able to tell which homes

were likely burned or not, and that's what we did for the Hiner, that's what we did in Maui,
