Insect Orientation: The Travails of Going Straight

The Effects of Carbon Nanotube Orientation and Aggregation on Static Behavior of Functionally Graded Nanocomposite Cylinders

In this paper, the effects of carbon nanotube (CNT) orientation and aggregation on the static behavior of functionally graded nanocomposite cylinders reinforced by CNTs are investigated based on a mesh-free method. The used nanocomposites are made of the straight CNTs that are embedded in an isotropic polymer as matrix. The straight CNTs are oriented, randomly or aligned or local aggregated int...

Dung Beetles Use the Milky Way for Orientation

When the moon is absent from the night sky, stars remain as celestial visual cues. Nonetheless, only birds, seals, and humans are known to use stars for orientation. African ball-rolling dung beetles exploit the sun, the moon, and the celestial polarization pattern to move along straight paths, away from the intense competition at the dung pile. Even on clear moonless nights, many beetles still...

Morphological and Anatomical Studies of the Ovary Galls of Sesamum indicum l. Induced by the Gall Midge, Asphondylia sesami Felt

The organization of gall on the ovary ofSesamum indicum L induced by the gall midge, Asphondylia sesami Felt, not only affects biochemical equilibrium of the host but also causes disturbed vegetative growth and reduced seed-setting. The toxicity created by the gall maker induces the re-orientation of vasculature Cecidogenetic stimuli lead to excessive hypertrophy and hyperplasy forming the gall...

Trajectory Tracking of AR.Drone Quadrotor Using Fuzzy Logic Controller

In this paper, Fuzzy Logic Controller (FLC) is implemented in the AR.Drone quadrotor in order to make it follow a given trajectory reference. The distance between the position and angle of the AR.Drone to the reference point is used as the input of the FLC. As for the output, pitch value and yaw rate will be the controlling signal for the AR.Drone. The navigation data of the AR.Drone are forwar...
