A Nonlinear Extension of Parametric Model Embedding for Dimensionality Reduction in Parametric Shape Design

ABSTRACT Dimensionality reduction is essential in simulation‐based shape design, where high‐dimensional parameterizations hinder optimization, surrogate modeling, and systematic design‐space exploration. Parametric Model Embedding (PME) addresses this issue by constructing reduce...

Multi-Channel Neighborhood-Constrained Variational Mode Decomposition

In many multi-channel engineering problems, the information relevant to the task is concentrated in one channel, while the other information plays an auxiliary role. In forecasting, the quantity to be predicted is the primary source of information and the covariates support it; i...

Hierarchical maritime traffic network generation from large AIS datasets: application to the West Mediterranean Sea case

Abstract We present a hierarchical scalable methodology to analyze the maritime traffic of year 2022 associated with cargo, tanker, and passenger vessels traveling within the West Mediterranean Sea. The methodology is based on data-mining and machine learning techniques to proces...

Fluid–body interactions on a flexible three-dimensional composite hydrofoil

Abstract This study presents an experimental investigation of the flow around a three-dimensional flexible hydrofoil at Reynolds numbers between $${3.6}\times {10}^{5}$$ 3.6 × 10 5 and $${7.2}\times {10}^{5}$$ 7.2 × 10 5 and angles of attack from $${-8}^{\circ }$$ - 8 ∘ to $${8}^...
