Time-dependent flows are notoriously challenging for classical linear stability analysis. Most progress in understanding the of these has been made time-periodic via Floquet theory focusing on time-asymptotic stability. However, little attention given to transient intracyclic periodic since no general tools exist its In this work, we explore potential using recent framework optimally time-depen...

Bone has the capacity to alter its mass and structure to its mechanical environment. Osteocytes are the predominant bone cells and it is generally accepted that the osteocytes are the professional mechanosensors of bone. A strain-derived fluid flow through the lacuno-canalicular porosity seems to mechanically activate them, resulting in the production of signalling molecules such as nitric oxid...

The dynamics of one-dimensional, piston-driven hydrogen–air detonations are predicted in the presence of physical mass, momentum and energy diffusion. The calculations are automatically verified by the use of an adaptive wavelet-based computational method which correlates a user-specified error tolerance to the error in the calculations. The predicted frequency of 0.97 MHz for an overdriven pul...
