Some Aspects Related to Drones

Relly Victoria Virgil Petrescu
2020 American Journal of Engineering and Applied Sciences  
The flight has already reached a point of great development, but at this moment, the drones that have recently reacted have started to develop very fast and occupy important places in the class of aircraft  ...  and they will surely develop rapidly and further, being the ones that will make their mark on future flights at low or medium altitude.  ...  On the platform of the North Station (Bucharest, Romania), at line four, young X is walking restlessly, although the train will arrive in just over 44 min.  ...

Pairwise and collective behavior between model swimmers at intermediate Reynolds numbers [article]

Thomas Dombrowski, Hong Nguyen, Daphne Klotsa
2021 arXiv   pre-print
We also studied a system of 122 swimmers and found the collective behavior transitioned from in-line network-like connections to small, transient in-tandem clusters as the Reynolds number increased, consistent  ...  Notably, the in-tandem V pair switched its swim direction at a higher Re than the single swimmer while the in-tandem orbiting pair switched at a lower Re.  ...  The network is composed of many parallel in-line pair strands (green), as well as in-tandem V pairs (blue). The identified pairs are consistent with the pairs we expect to see at Re = 1.  ...
