Abstract: Direction-of-arrival (DOA) estimation is critical for electromagnetic systems, yet conventional multichannel array-based methods incur prohibitive hardware costs. They struggle with handling ...
Abstract: Federated learning (FL) preserves data privacy by exchanging gradients instead of local training data. However, these private data can still be reconstructed from the exchanged gradients.
Researchers in China developed a new compressed air energy storage system that uses flooded roadways in abandoned coal mines to store compressed air and heat for nighttime power generation.
