Path planning of unmanned aerial vehicles (UAVs) is one the vital components that supports their autonomy and deployment ability in real-world applications. Few path-planning techniques have been thoroughly considered for multirotor UAVs pursuing ground moving targets (GMTs) with variable speed direction. Furthermore, most are generally devised without taking into consideration wind disturbance...

The repeated co-occurrence of cold spells over Eastern North America and wet or windy extremes Western Continental Europe during recent winters, has led to hypothesize a link between the two. Here, we analyze interplay large-scale atmospheric circulation co-occurring in Europe. We collectively term these occurrences compound cold–wet–windy extremes. leverage approach grounded dynamical systems ...

In this paper the Min-Max version of the Windy Rural Postman Problem with several vehicles is introduced. For this problem, in which the objective is to minimize the length of the longest tour in order to find a set of balanced tours for the vehicles, we present here an ILP formulation and study its associated polyhedron. Based on its partial description, a branch-and-cut algorithm has been imp...

Atmospheric gas saturation levels were monitored throughout a 40-km reach of the upper Colorado River during the summer and fall of 1995 to identify possible sources of gas supersaturation in the river. Gas saturation data from seven fixed sampling points and 40 random sampling points were analyzed using analysis of variance (ANOVA) and multiple regression methods. The lowest total gas saturati...
