Mask to identify polluted periods during the Arctic Ocean 2018 expedition

Julia Schmale, Andrea Baccarini

Aerosol and trace gas measurements are strongly affected by the ship exhaust and other human activities (e.g., helicopter flights). Therefore, it is important to discriminate between clean and polluted periods. This mask provides an indication of clean per ...

Downside Up:Rethinking Parcel Position for Aerial Delivery

Dario Floreano, Przemyslaw Mariusz Kornatowski, William John Stewart, Mir Alikhan Bin Mohammad Feroskhan

The conventional approach to parcel placement in most delivery drone designs today is to place the parcel centrally beneath the drone's rotor plane. However, if the parcel is too large, this will result in an obstruction of the propeller slipstream, incurr ...

A point vortex transportation model for yawed wind turbine wakes

Fernando Porté Agel, Haohua Zong

In this study, stereo particle imaging velocimetry measurements are performed at multiple streamwise locations behind a yawed wind turbine to reveal the formation mechanisms of the counter-rotating vortex pair (CVP), and a point vortex transportation (PVT) ...
