Workplace hearing loss is one of the most common work-related illnesses. While hearing loss is preventable with earplugs, ...

Doppler ultrasound works by measuring frequency shifts in sound waves as they bounce off moving red blood cells, translating them into waveforms that reflect blood flow patterns. In obstetrics, this ...

Abstract: Extensive work has demonstrated the excellent performance of orthogonal time frequency space (OTFS) modulation in high-mobility scenarios. Time-variant wideband channel estimation serves as ...

Abstract: Frequency-based localization methods exploiting the Doppler effect typically assume uniform sensor motion, which is difficult to achieve in practice, especially for unmanned aerial vehicles ...
