UAV-aided maritime communication over the Pacific Ocean using the elevated duct toward future wireless networks
Published 2025-04-01“…The study found: (1) the feasibility of realizing over-horizontal, GHz-bandwidth microwave transmission links within the elevated duct; (2) The path loss budget of 189 dB is marked with black isoline, implying that the receiver of the UAV-aided communication system in the ducting layer can receive and demodulate microwave signals with 1 GHz-bandwidth; (3) QPSK stands out for its relative compromise in bandwidth efficiency and hardware implementation difficulty for signals of six digital modulations. …”

The “Projection-by-Projection” (PbP) criterion for multiaxial random fatigue loadings
Published 2018-12-01“…This work is motivated by the increasing interest towards the application of the “Projection-by-Projection” (PbP) spectral method in finite element (FE) analysis of components under multiaxial random loadings. To help users and engineers in developing their software routines, this paper presents a set of numerical case studies to be used as a guideline to implement the PbP method. …”

Association Analysis of Benzo[<i>a</i>]pyrene Concentration Using an Association Rule Algorithm
Published 2025-05-01“…The clustering performance was enhanced by optimizing the K-means method using the sum of squared error. The efficiency and reliability of the traditional Apriori algorithm were enhanced by restructuring its candidate itemset generation process, specifically by (1) generating C<sub>2</sub> exclusively from frequent itemset L₁ to avoid redundant database scans and (2) implementing the iterative pruning of nonfrequent subsets during L<sub>k</sub> → C<sub>k+1</sub> transitions, adding the lift parameter, and eliminating invalid rules. …”
