Model reduction of traveling-wave problems via Radon cumulative distribution transform (2021)
Journal Article
Wolf, W. R., Ren, J., Wolf, W. R., & Mao, X. (2021). Model reduction of traveling-wave problems via Radon cumulative distribution transform. Physical Review Fluids, 6(8), Article L082501. https://doi.org/10.1103/PhysRevFluids.6.L082501

Traveling-wave problems, due to their sizable Kolmogorov n-width, have brought critical challenges to conventional model reduction techniques. This study aims to provide insights into this problem by exploiting the Radon cumulative distribution trans...

A hybrid solution for offshore wind resource assessment from limited onshore measurements (2021)
Journal Article
Elshafei, B., Peña, A., Xu, D., Ren, J., Badger, J., Pimenta, F. M., …Mao, X. (2021). A hybrid solution for offshore wind resource assessment from limited onshore measurements. Applied Energy, 298, Article 117245. https://doi.org/10.1016/j.apenergy.2021.117245

In wind resource assessments, which are critical to the pre-construction of wind farms, measurements by LiDARs or masts are a source of high-fidelity data, but are expensive and scarce in space and time, particularly for offshore sites. On the other... Read More about A hybrid solution for offshore wind resource assessment from limited onshore measurements.

Image-based flow decomposition using empirical wavelet transform (2020)
Journal Article
Ren, J., Mao, X., & Fu, S. (2021). Image-based flow decomposition using empirical wavelet transform. Journal of Fluid Mechanics, 906, Article A22. https://doi.org/10.1017/jfm.2020.817

We propose an image-based flow decomposition developed from the two-dimensional (2-D) tensor empirical wavelet transform (EWT) (Gilles, IEEE Trans. Signal Process., vol. 61, 2013, pp. 3999-4010). The idea is to decompose the instantaneous flow data,... Read More about Image-based flow decomposition using empirical wavelet transform.
