be robust to changes in the local mapped environment. However, for many scenarios typical of UAV operations, it is still desirable to implement waypoint-driven guidance trajectories off-line to ensure optimality of the chosen flight profile. This is particularly true of lightweight micro-UAVs where optimal path planning is essential to maximise operational effectiveness against the low range an...

In this paper, first the optimal trajectories are defined by a fixed end-time, continuous-thrust trajectory which minimizes terminal cost at end of an inter-planetary appending multi-body dynamic equations defining motion set Lagrange multipliers or co-states. The solution these co-states and for end-time obtained solving two-point boundary value problem along with steering control law, is used...

BACKGROUND AND AIMS Simple models of herbaceous plant growth based on optimal partitioning theory predict, at steady state, an isometric relationship between shoot and root biomass during plant ontogeny, i.e. a constant root-shoot ratio. This prediction has received mixed empirical support, suggesting either that optimal partitioning is too coarse an assumption to model plant biomass allocation...

We consider the problem of optimizing trajectory an Unmanned Aerial Vehicle (UAV). Assuming a traffic intensity map users to be served, UAV must travel from given initial location final position within duration and serves on its way. The consists in finding optimal that minimizes certain cost depending velocity amount served traffic. formulate using framework Lagrangian mechanics. derive closed...
