In this paper we show that Janus colloids, which are spherical particles with hybrid anchoring conditions, have preferable orientations in cholesteric media depending on the cholesteric wave vector. Simulations reveal that the tilt angle of a particle varies greatly with variation of the particle diameter to the cholesteric pitch ratio, which makes it possible to stabilize the appropriate parti...

This research proposes the control system structure for a small-scale wind turbine. Significantly, maximum power point tracking algorithm (MPPT) and pitch angle controller are deeply analyzed; this is base proposing strategy of MPPT combined with pitch-angle in wide speed range wind. article also researches converters, then analyses advantages each converter to choose suitable In design, expert...

In the present paper, the controlled flight of fruitflies after voluntary takeoff is studied. Wing and body kinematics of the insects after takeoff are measured using high-speed video techniques, and the aerodynamic force and moment are calculated by the computational fluid dynamics method based on the measured data. How the control moments are generated is analyzed by correlating the computed ...
