Frost heave behavior of coarse-grained materials for high-speed railways subgrade: experimental analysis and machine learning predictive modeling [PDF]
Scientific ReportsCoarse-grained subgrade fill has traditionally been considered frost-heave-insensitive. However, uneven frost heave in such materials has become a critical constraint for high-speed railways (HSRs) in cold regions.

Development of Coupled Numerical Model between Floating Caisson and Anti-Oscillation Tanks
Journal of Marine Science and Engineering, 2023 Floating caissons can oscillate owing to ocean waves when towed to an installation site. To reduce these oscillations, free-surface anti-oscillation tanks mounted on floating caissons have been proposed. However, no coupled numerical model exists between

EVALUATION OF INTERCEPTOR DESIGN TO REDUCE DRAG ON PLANING HULL
Brodogradnja, 2022 A planing hull is a high-speed craft with relatively complex hydrodynamic characteristics. An increase in speed can induce a significant change in trim angle with an increment in ship drag. One solution to reduce ship resistance is to use an interceptor.
