In the domain of consumer electronics, vehicular edge computing (VEC) technology is emerging as a novel data processing paradigm within networks. By sending tasks related to applications edge, this model makes it easier for power be spread out. This lets interactive services respond quickly. Nevertheless, computational resources at servers are inherently limited and often tasked with handling multiple concurrent operations. The inefficacious allocation these significantly impairs efficiency...

The advancement of mobile multimedia communications, 5G, and Internet Things (IoT) has led to the widespread use edge devices, including sensors, smartphones, wearables. This generated in a large amount distributed data, leading new prospects for deep learning. However, this data is confined within silos contains sensitive information, making it difficult be processed centralized manner, particularly under stringent privacy regulations. Federated learning (FL) offers solution by enabling...
Improving transport current has been the primary issue for practical application of superconducting wires and tapes. However, porous nature powder-in-tube (PIT) processed iron-based tapes is thought to be one important reasons low Jc values.
