— We present a path planning algorithm for time-critical cooperative surveillance using a set of unmanned aerial platforms. The unique constraints imposed by maneuver limits and body-fixed cameras make the problem quite challenging. An Integer Programming(IP)-based strategy for successfully operating within these constraints is developed. IP is applied over(More)

— We present a path planning algorithm for cooperative surveillance using a set of heterogeneous unmanned vehicles. The paper describes our overall framework and algorithm for the computation of trajectories that maximize spatio-temporal coverage while satisfying hard constraints such as collision avoidance and specifications on initial and final positions.(More)
Recent developments of autonomous unmanned vehicles and sensor systems allow automated approaches to surveillance with minimal human supervision or intervention. Indeed as the number of vehicles increases it becomes increasingly difficult and even impossible for direct human supervision. Our work addresses the generation of team flight plans and controllers(More)
— We provide a system-theoretic analysis of the mathematical model of lactose induction in E.coli which predicts the level of lactose induction into the cell for specified values of external lactose. Depending on the levels of external lactose and other parameters, the Lac operon is known to have a low steady state in which it is said to be turned off and(More)
