Inertial Migration in Micro-Centrifuge Devices

, 2023
Within microcentrifuge devices, a microfluidic vortex separates larger particles from a heterogeneous suspension using inertial migration, a phenomenon that causes particles to migrate across streamlines. The ability to selectively capture particles based on size differences of a few microns makes microcentrifuges useful diagnostic tools for trapping ...

Development of an Embedded In-Mass Inertial Device for Landslide and Rockfall Monitoring

Applied Sciences
Early-stage landslides and rockfalls are often characterized by very small internal accelerations associated with creep and progressive deformation, which are difficult to capture using conventional surface-based displacement monitoring techniques.

LOCATE-US: Indoor Positioning for Mobile Devices Using Encoded Ultrasonic Signals, Inertial Sensors and Graph-Matching

Sensors, 2021
Indoor positioning remains a challenge and, despite much research and development carried out in the last decade, there is still no standard as with the Global Navigation Satellite Systems (GNSS) outdoors. This paper presents an indoor positioning system

Ekman-Inertial Instability

, 2020
We report on an instability, arising in sub-surface, laterally-sheared geostrophic flows. When the lateral shear of a horizontal flow in geostrophic balance is of opposite sign to the Coriolis parameter, and exceeds it in magnitude, embedded ...

Composite hodographs and inertial oscillations in the nocturnal boundary layer [PDF]

, 2011
In this work the dynamic behaviour of the wind in the nocturnal boundary layer is studied, with a particular focus on systematic behaviour of the near-surface wind.
