Abstract: This work compares the effectiveness of four image reconstruction techniques for a ring-array photoacoustic computed tomography (PACT) system: the delay-and-sum (DAS), the interpolated model ...

Abstract: This article presents a novel phased array antenna calibration method. Unlike conventional phased array calibration methods equipped with only one probe antenna in the far-field setup, ...

I don’t typically write responses to other opinion pieces, but there was one two weeks ago about new techniques in elementary math education that has inspired me. The main complaint was that there are ...

When it comes to hard problems, computer scientists seem to be stuck. Consider, for example, the notorious problem of finding the shortest round-trip route that passes through every city on a map ...

Four years ago, I was given a fantastic opportunity to be a math coach for a primary years program. But when I started, there was no framework to work within, no script to follow. I was starting from ...

Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I really like to use numerical calculations without all the fancy programming ...

Not long ago, blue states typically outperformed red ones when it came to education. That is changing. Blue states like Oregon and Washington experienced significant drops in reading and math scores ...

The Ohio Senate’s version of the state budget bill would change the way Ohio students learn math. Ohio schools’ math and reading scores on state tests dropped significantly during the COVID pandemic.
