Fun with Bessel Functions
Well, I certainly forget things faster than I learn them. Today is a quick review of Bessel functions and their applications to signal processing. The Bessel functions appear in lots of situations (think wave propagation and static potentials), particularly those that involve cylindrical symmetry. While special types of what would later be known as Bessel…

Wind speed calculation
I want to know the impact of wind on endurance. So we have something like this: This gives us 8 cases of wind direction: From this we can infer that going to the center from one of the 8 directions. So an overall flight path would look like this: If each grid cell is a…
