Vibration Analysis of 2D Porous Functionally Graded Beams With Inclined Cracks Under Thermo‐Hygro‐Mechanical Coupling

ABSTRACT This work provides an in‐depth investigation into wave propagation in functionally graded material (FGM) beams subjected to coupled thermo‐hygro‐mechanical loading. The proposed model explicitly accounts for the presence of cracks, material porosity, axial pre‐stress, an...

Physiologically-aware data generation: A differentiable HMM and frequency-domain Transformer GAN approach

The generation of multivariate medical time series, such as intensive care unit (ICU) trajectories, remains challenging because patient signals are highly heterogeneous, non-stationary, and strongly multimodal. In this paper, we present a methodological proof-of-concept for the s...

Genetic-Algorithm Optimization of Dynamic Efficiency in Bidirectional Porous Functionally Graded Beams

This study develops an analytical–evolutionary framework for optimizing the dynamic efficiency of bidirectional porous functionally graded beams. Touratier’s higher-order shear deformation theory is coupled with a real-coded genetic algorithm. The material-gradation indices in th...
