Anticollision Method of Active Magnetic Guidance Ranging for Cluster Wells

Designated magnetic field design for magnetic drug guidance in BNCT

In this paper, a local magnetic field was designed and simulated using a Helmholtz coil along with a ferromagnetic core with an appropriate geometric Structure to concentrate a magnetic flux. This field can be used for magnetic guiding of Boron-borne drugs in BNCT.

Image-Based Ranging and Guidance for Rotorcraft

Rotorcraft operating at low altitudes require navigational schemes for locating the terrain and obstacles. Due to the covert nature of missions to be accomplished, a passive navigation scheme is desirable. This paper describes the development of a passive navigation scheme combining image sequences from a vehicle mounted camera with vehlcle motion variables. Geometric properties of perspective ...

Magnetic Guidance of Organisms

Magnetic guidance of organisms.

Human beings have used magnetic compasses as navigation aids since at least the eleventh century AD (55, 63). The magnetic compass facilitated long-distance navigation on the'high seas and was one of the technological advances that led to the great European voyages of discovery in the thirteenth and fourteenth centuries. The invention of the magnetic compass is usually credited to the Chinese (...

A Reduction Method of Cogging Torque for Magnetic Gears

Nowadays, magnetic gears (MGs) have become an alternative choice for mechanical gears because of their low maintenance, improved durability, indirect contact between inner and outer rotors, no lubrication, and high efficiency. Generally, although these advantages, MGs suffer from inherent issues, mainly the cogging torque. Therefore, cogging torque mitigation has become an active research area....
