Abstract: Brushless machines with interior permanent magnets (PMs) are mostly made with PM geometries inconsistent with the polar coordinates of the rotor cross section. Therefore, without any ...

I make short, to-the-point online math tutorials. I struggled with math growing up and have been able to use those experiences to help students improve in math through practical applications and tips.

While data-driven collective variables (CVs) have been applied to various complex biological problems, such as ligand binding, their transferability across different substrates has not been thoroughly ...

Seven of the eight Arctic nations are members of NATO yet collectively, they trail Russia's ice-breaker capacity. This was even before adding in the icebreakers China has built as it proclaims itself ...

An optical vortex, as one of the most prominent candidates for structured light, is typically identified as a phase or polarization singularity, resulting in a doughnut-shaped pattern and its carried ...

A big part of NASA Glenn’s mission over the years has been to design and test propulsion systems and that will continue during Artemis. Propulsion has been a technological sweet spot for Glenn since ...

Since its inception in 2017, the Polar Institute has become a premier forum for discussion and policy analysis of Arctic and Antarctic issues, and is known in Washington, DC and elsewhere as the ...

Metamaterials are composed of periodic subwavelength metallic/dielectric structures that resonantly couple to the electric and magnetic fields of the incident electromagnetic waves, exhibiting ...
