In this paper, we study sensor fusion for the attitude stabilization of Micro Aerial Vehicles (MAVs), in particular mechanical flying insects. First, following a geometric approach, a dynamic observer is proposed which estimates attitude based on kinematic data available from different and redundant bioinspired sensors such as halteres, ocelli, gravitometers, magnetic compass and light polariza...

a study was conducted on six years old trees of almond, shahroud cv. (no. 18), in a three-year trial (2002-04) at mashhad agricultural research station. the experiment was done on the basis of completely randomized desigh with four replications. in the first and second years of the experiment, ethephon was sprayed in 15 and 20 days before the common time of harvesting, respectively. the concent...
