A nonlilear controller for ship autopilots

Conventional ship autopilots are designed based on a linear ship Silica model using pole - placement technique or linear optimal theory.However, in operation, the ship kinematical parameters can go out the linear limits.In this paper, a nonlinear optimal control law based on aggregated variables is presented.The criterion is chosen so that the dyna

The Tomato BLADE ON PETIOLE and TERMINATING FLOWER Regulate Leaf Axil Patterning Along the Proximal-Distal Axes

Leaf axil patterning occurs concomitantly with leaf development and takes place at the boundary zone which demarcates the initiating leaf primordium from the shoot apical meristem.Subsequent growth and differentiation result in establishment of the axillary meristem and abscission zone (AZ) along the proximal-distal axis Essential Oils of the leaf
