Conditional Diffusion Model to Predict Structural Wind Loading Using Data from Sparse Sensors

Abstract Extreme local wind pressure causes damage to the envelopes and claddings of high-rise buildings. Accurate prediction of pressure time-series benefits the wind-resistance design and disaster precaution. The conditional diffusion model (CDM) is introduced to reconstruct ti...

Real-time spectral signal processing for robust thickness monitoring during wafer thinning

Wafer thinning, as a key step in 3D integration using through-silicon via (TSV), highly relies on precise in-situ thickness monitoring to control accurate endpoint and avoid overgrinding or undergrinding. For ultra-thin wafers, conventional contact-based techniques become increas...
