PT Journal AU Aimene, Y Dorville, R Omrane, A TI Optimal control for trees trunk diameter estimation in rain forest ecology SO Applied Mathematical Sciences PY 2013 BP 807 EP 816 VL 7 IS 17-20 DE Missing data; Optimal control; Tree trunk diameter AB We study the optimal control question for an important mechanical problem related to tree trunk diameter variation in tropical forest ecology where some data are missing. Within a cost function, the control problem is formulated with a mechanical model that requires boundary conditions tosolve all equations. We give a characterization of the optimal measurement function for the tree trunk problem. ER
