Bacteriophage viruses spontaneously self-assemble in the presence of their component parts (certain protein molecules). It is believed that conformational switches, interacting chemical bonding sites that allow tentative incorrect bonds, facilitate this randomized assembly process. A onedimensional conformational switch is proposed and used to study the randomized assembly of mechanical parts. ...

This paper provides necessary conditions of optimality, in the form of a maximum principle, for optimal control problems of switching systems. Dynamics of the constituent processes take the form of stochastic differential equations with control terms in the drift and diffusion coefficients. The restrictions on the transitions or switches between operating modes, are described by collections of ...

We consider multiple unmanned aerial vehicles (UAVs) serving a density of ground terminals (GTs) as base stations. The objective is to minimize the outage probability GT-to-UAV transmissions. Optimal placement UAVs under different UAV altitude constraints and GT densities studied.
