Modern spectral analysis in HF radar remote sensing. [PDF]
, 1998 High-Frequency (HF) radar systems are currently used to collect wave data. By applying spectral analysis methods, such as the Fast Fourier Transform (FFT) method, to the radar backscatter from the ocean surface, the so-called Doppler spectrum is ...

Chebyshev collocation method for solving second order ODEs using integration matrices
Discrete and Continuous Models and Applied Computational Science, 2023 The spectral collocation method for solving two-point boundary value problems for second order differential equations is implemented, based on representing the solution as an expansion in Chebyshev polynomials. The approach allows a stable calculation of

Directed network Laplacians and random graph models
Royal Society Open Science, 2021 We consider spectral methods that uncover hidden structures in directed networks. We establish and exploit connections between node reordering via (a) minimizing an objective function and (b) maximizing the likelihood of a random graph model. We focus on
