A non-Darcy flow model for a non-cohesive seabed involving wave-induced instantaneous liquefaction
, 2021 Prediction of wave-induced instantaneous (oscillatory or momentary) liquefaction is particularly important for the design of offshore foundations. Most previous studies applied the linear Darcy model to characterize the porous flow in a seabed.

Impulse ageing of polymeric materials
, 2011 Impulse over-voltage is a common phenomenon in electric power systems. A switching impulse is created by a switching surge or local fault while a lightning impulse is due to direct lightning strike to high voltage plant such as an overhead line.

Motion and Heat Transfer in Turbulent Vortex Pairs
Engineering Transactions, 1978 A two-dimensional problem of turbulent vortex pairs originated by an instantaneous dynamical impulse (cylindrical puffs) or an instantaneous heat release (cylindrical thermals) is considered.

Advanced Materials, EarlyView.This study demonstrates the combination of magnetic nanoparticles and functional blowing agents into supraparticles. Upon induction heating, they actuate via rapid gas generation or extensive volume expansion. These supraparticles lift up to 25 000 times their own mass and rapidly open cured epoxy resins, providing a versatile strategy for fast micron ...
