CAMP ATTERBURY, Indiana–The Pentagon has been talking about rapidly scaling up drone forces for years—efforts that so far have produced interesting new prototypes and lively demonstrations. But while ...

One of the fundamental operations in machine learning is computing the inverse of a square matrix. But not all matrices have an inverse. The most common way to check if a matrix has an inverse or not ...

Whenever I move/rotate/scale any object in the 3D view using my graphics tablet (Gaomon M10K 2018), the objects do their thing fine until I confirm by tapping the nub. If I do that, the object ...

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 ...

Dozens of machine learning algorithms require computing the inverse of a matrix. Computing a matrix inverse is conceptually easy, but implementation is one of the most challenging tasks in numerical ...

The Philadelphia Phillies are sending a message to the rest of the league about what their rotation can look like at the peak of its powers. To open the series against the Tampa Bay Rays, they threw ...

After the Baltimore Orioles lost Corbin Burnes in free agency, instead of going after another high-end ace, the strategy by general manager Mike Elias was to create depth in the rotation. That ...

Abstract: A 3D wideband high-gain circularly-polarized array antenna (CPAA) with low radar cross section (RCS) is presented in this manuscript. Its element contains four 3D radiation structures fed by ...
