Time-Averaged Behavior of Gap Flow Between Two Side-by-Side Circular Cylinders

open access: yes, 2016
The time-averaged behavior of gap flow between two stationary side-by-side circular cylinders immersed in the subcritical Reynolds number regime and its variation with gap spacing are presented.

Real-time path planning with limited information for automonous unmanned air vehicles

open access: yes, 2008
We propose real-time path planning schemes employing limited information for fully autonomous unmanned air vehicles (UAVs) in a hostile environment. Two main algorithms are proposed under different assumptions on the information used and the threats ...
