This paper addresses the robust control for a slung-mass quadrotor under abrupt velocity changes.The proposed algorithm is here based on a sliding mode controller applied to the quadrotor translational dynamics considering the slung-mass angle as feedback.A Lyapunov candidate function is used to demonstrate system stability.Numerical simulations ar
Using microspherical scaffolds as building blocks to repair bone defects of specific size and shape has been proposed as a tissue engineering strategy.Here, phosphate glass (PG) microcarriers doped with 5 mol % TiO 2 and read more either 0 mol % CoO (CoO 0%) or 2 mol % CoO (CoO 2%) were investigated for their ability to support osteogenic and vascu
When a video of someone speaking is paused, the stationary image of the speaker typically appears less flattering than the video, which contained motion.We call this the Frozen Face Effect (FFE).Here we report six experiments intended to quantify this effect and determine its cause.In Experiment 1, video clips of people speaking in naturalistic set
