Robust and Rapid Air-Borne Odor Tracking without Casting

Robust and Rapid Air-Borne Odor Tracking without Casting.

Casting behavior (zigzagging across an odor stream) is common in air/liquid-borne odor tracking in open fields; however, terrestrial odor localization often involves path selection in a familiar environment. To study this, we trained rats to run toward an odor source in a multi-choice olfactory arena with near-laminar airflow. We find that rather than casting, rats run directly toward an odor p...

Robust Tracking via Convolutional Networks without Learning

Deep networks have been successfully applied to visual tracking by learning a generic representation offline from numerous training images. However the offline training is time-consuming and the learned generic representation may be less discriminative for tracking specific objects. In this paper we present that, even without learning, simple convolutional networks can be powerful enough to dev...

AIR PRESSURE SIMULATION IN CASTING MOLDS

During mold filling, molten metal can only advance as quickly as the air inside thecavity is expelled. In this work an analytical model describing air flow is developed based on aincompressible flow theory. Air pressure has serious effects upon the filling behaviour such assurface profile and filling time. In this work a new mathematical model is proposed for calculationthe air pressure during ...

Robust output tracking control of VTOL aircraft without velocity measurements ⋆

In this paper, we develop a nonlinear controller to achieve causal output tracking for a non-minimum phase vertical take-off and landing (VTOL) aircraft without velocity measurements. Due to the presence of disturbances, auxiliary control inputs are introduced in the state observer to attenuate their effects. By decomposing the original system into one minimum phase and one non-minimum phase su...
