Sensitivity Analysis of Partial Differential Equations With Applications to Fluid Flow
… in fluid flows by analyzing the spectrum of the linearized Navier-Stokes equations. However, for many simple flows, this approach has failed to match experimental results. Recently, new scenarios for transition have been proposed that are based on the non-normality of the linearized …

Nonlinear Solutions to a Two-Layer Quasi-Geostrophic Model of the Gulf Stream
<p>The Gulf Stream shows a large meander off Cape Hatteras. This is driven by an energy conversion process known as baroclinic instability and observations suggest that nonlinearity is an important part in this process. In order to understand the fundamental role of nonlinearity in baroclinic …

Implications of nonlinear suspension behaviour for feedforward control of road noise in cars
Active control offers a lightweight solution to the problem of low frequency structure-borne road noise in cars. Feedforward control of road noise is predominantly limited by the difficulty of finding reference signals that are highly coherent with the sound in the cabin. One factor that could …

Wave Engineering in Time Modulated, Nonlinear, and Anisotropic Metamaterials
… wave matter interactions is central to a myriad of electromagnetic wave-based applications. During the past decades, research on extreme wave manipulation has been revolutionized by artificially engineered materials (metamaterials) and by adding new aspects to the wave-matter interactions that …
