Australia has always had heat waves. But this week's heat wave in southeastern Australia is something else. Temperatures in some inland towns in South Australia, New South Wales and Victoria were up ...

Researchers at Sichuan University have proposed a four-level modulation strategy for dual three-phase open-winding PMSM drives, offering higher efficiency and lower current harmonic in such ...

BERLIN & NEW YORK--(BUSINESS WIRE)--Qdrant, the leading high-performance open-source vector database, today introduced its platform-independent GPU-accelerated vector indexing. This new feature ...

This vector illustration depicts a diagram comparing high and low-frequency waves in physics. It shows the visual difference between high and low pitch sound waves, with high-frequency waves ...

Abstract: Discontinuous pulsewidth modulation (DPWM) has found widespread application in three-level ac/dc converters due to its superior efficiency. However, conventional DPWM, characterized by ...

For decades, atomic clocks have been the gold standard for precise timekeeping. However, their bulky size and sensitivity to environmental factors have limited their use outside of controlled ...

While much of our planet’s air and seas are stirred at a tempest’s whim, some features are far more regular. At the equator, thousand-kilometer-long waves persist amid the chaos. In both the ocean and ...
