Unbiased two-windows approach for Welch's method
Eduardo Martini
Periodogram methods are widely used for the estimation of power- and cross-spectra, of which Welch's method is the most popular. Previous studies have analyzed the variance of the…

Solutions to aliasing in time-resolved flow data
Ugur Karban, Eduardo Martini, Peter Jordan +2
Avoiding aliasing in time-resolved flow data obtained through high fidelity simulations while keeping the computational and storage costs at acceptable levels is often a challenge.…

Resolvent-based tools for optimal estimation and control via the Wiener-Hopf formalism
Eduardo Martini, Junoh Jung, André V. G. Cavalieri +2
The application of control tools to complex flows frequently requires approximations, such as reduced-order models and/or simplified forcing assumptions, where these may be conside…
