Curved-Stern Internal Waves with Applied Pressure in a Finite-Depth Two-Layer Fluid

The wave train generated by a moving vessel remains a persistent challenge in ship hydrodynamics, particularly in stratified oceans where internal waves contribute significantly to drag. This research investigates steady interfacial wave generation by flow past a semi-infinite curved plate in a two-layer fluid where bo...

Dynamic Pressure Response and Wave Resistance in Forced Korteweg–DeVries Systems

Weakly nonlinear free-surface flows past disturbances are traditionally modeled using the forced Korteweg–de Vries (fKdV) equation with a prescribed instantaneous pressure field. However, physical wake responses possess finite relaxation times and advection scales that diagnostic algebraic closures fail to capture. Thi...

Novel Mittag-Leffler-Based Aggregation Operators for Complex Fuzzy Sets, with an Illustrative Application to Generative AI Diagnostic-System Evaluation

Aggregation operators are central to multi-criteria decision-making under complex fuzzy information, where the additional phase dimension of complex fuzzy sets captures periodic or cyclical uncertainty beyond the reach of classical fuzzy sets. Existing Archimedean families used in the complex-fuzzy aggregation-operator...
