Researchers at Skoltech have developed an ultra-compact electro-optic modulator based on silicon photonics and plasmonics ...
This repository provides code and workflows to test several state-of-the-art vehicle detection deep learning algorithms —including YOLOX, SalsaNext, and RandLA-Net— on a Flash Lidar dataset. The ...
Researchers analyzing pulsar data have found tantalizing hints of ultra-slow gravitational waves. A team from Hirosaki University suggests these signals might carry “beats” — patterns formed by ...
ABSTRACT: Rolling element bearings are commonly used in rotating machines to transmit rotation and power. On the other hand, bearing faults could be the most common reason for machinery imperfections.
On July 22, 2025, Radio World republished one of my articles from October 25, 2011. The title was, “Rebuild That Relic of an AM Transmitter.” The idea of the article is to keep an old tube-type AM ...
I'm trying to limit the bandwidth of signals in my dataset with the following configuration: seed = 1234 signal_bandwidth_min = 100_000 signal_bandwidth_max = 500_000 sample_rate = 80_000_000 ...
Numbers stations demonstrate decades of robust RF communication design, offering insights into propagation optimization and one-way transmission security. Explore AM/CW modulation, ionospheric physics ...
