High school trigonometry combined with four-quadrant multipliers can be exploited to yield sinusoidal frequency doublers. Nothing non-linear is involved, which means no possibly strident filtering ...

Quarterly or twice a year? If you find your friends suddenly arguing about the frequency of financial reporting for listed companies, and you feel left out for lacking strong opinions on the matter, I ...

Weather patterns channeling moisture into the state have led to an abundance of lightning strikes that have ignited hundreds of wildfires. By Amy Graff Amy Graff is a San Francisco-based reporter on ...

Abstract: Recently, the concept of complex frequency (CF) has been introduced to unify the rate of change of voltage (RoCoV) and angular frequency, facilitating the development of CF-based droop ...

Compared with workers onsite full-time, those who worked fully remote had a 59% reduction in the likelihood of short sleep duration. High-frequency remote work is negatively associated with short ...

Frequency capping has long relied on a static “set it and forget it” mindset: once every 24 hours, three times every seven days and so on. This passive approach to avoiding consumer ad overexposure ...

Abstract: This article presents a comprehensive analysis of frequency-selective surfaces (FSSs) under oblique incidence, covering the frequency, angular, and polarization domains through their ...

Josephson junctions, as pivotal components of modern technologies such as superconducting quantum computing, owe their prominence to their unique nonlinear properties at low temperatures. Despite ...

The Ultra-Chron Carbon is the latest chapter in a storied legacy that spans over half a century. To truly appreciate the significance of this new model by Longines, we must first understand its rich ...
