Multi-robot monitoring in dynamic environments with guaranteed currency of observations
Abstract-- In this paper we consider the problem of monitoring a known set of stationary features (or locations of interest) in an environment. To observe a feature, a robot must v...

Internal Stabilization by Noise of the Navier--Stokes Equation
One shows that the Navier-Stokes equation in O⊂Rd, d = 2, 3, around an unstable equilibrium solution is exponentially stabilizable in probability by an internal noise controller...
