Abstract: This paper proposes an algorithm for estimate the damping ratio of power system oscillation in real time. In this paper, we utilize the Four-Max-Min-Points (FMMP) method to estimate the ...

The capacity to damp mechanical vibrations is one of the most important properties of granite-epoxy composites, even superior to the cast iron one. For this reason, these materials have been adopted ...

Gallium nitride, a semiconductor that can operate at high voltages, temperatures, and frequencies, has enabled technologies from LED lighting to high-power electronics. Now Cornell researchers have ...

In this post, we will take a gentle dive into logarithmic amplifiers—commonly known as log amps—those quietly powerful circuits that work behind the scenes to decode exponential signals and tame wide ...

Researchers have discovered quantum oscillations inside an insulating material, overturning long-held assumptions. Their work at the National Magnetic Field Laboratory suggests that the effect ...

Waves of synchronized, coordinated neuronal activity have been observed and studied in the brain for over a century. But for the first time, Yale researchers have identified where a certain type—known ...

Bloch oscillations are periodic oscillations of quantum particles in a repeating energy "landscape" (e.g., a crystal lattice) that are subjected to a constant force. These particle motions have been ...

The iPhone 16 Pro packs an incredible camera setup for both still images and for video production -- including its fun 4K slow-motion mode. But to help it capture pro-standard video footage, it also ...

From cadence to stride length and resting heart rate to average pace, runners – and, of course, most running apps and GPS running watches – now record and track a wealth of health and fitness-related ...

Modeling experiments show Pacific warm and cold patches persisted even when continents were in different places The El Niño event, a huge blob of warm ocean water in the tropical Pacific Ocean that ...
