The identification of hidden conducting permeable objects from measurements the perturbed magnetic field taken over a range low frequencies is important in metal detection. Applications include identifying threat items security screening at transport hubs, location unexploded ordnance, and antipersonnel landmines areas former conflict, searching for archeological significance recycling valuable...

Visualizations of reduced-order representations stratified wakes Reynolds number $$Re \in \{5,25,100\}\times 10^3$$ are presented at a fixed internal Froude number. The constructed by applying proper orthogonal decomposition (POD) to numerical datasets that high-resolution, three-dimensional and time-dependent. Due the transient nature flow, dynamics be represented highly non-stationary, posing...
