A Novel Hybrid Physical-Layer Authentication Scheme for Multiuser Wireless Communication Systems
Published 2023“…In addition, the detection probability (DP) rises at high legitimate and intruder links SNRs, while it degrades for low SNR (i.e., noisy attributes observations). Finally, the more significant the difference between the actual malign and benign nodes’ CFOs, the better the DP.…”

An efficient second order ImEx scheme for the shallow water model in low Froude regime
Published 2024“…Through a series of one-and two-dimensional test cases, the method is shown to achieve second-order accuracy for different Froude numbers. Additionally, the computational efficiency of the proposed method is compared with that of a fully explicit scheme, demonstrating significant time savings with the ImEx approach, particularly in scenarios governed by low Froude numbers.…”
