FOR MORE THAN 50 YEARS, cardiac surgeons and biomedical engineers at the Texas Heart Institute (THI) have been questing for an artificial heart that can fully replace natural ones, which are in terribly short supply for transplant. They've seen their share of metal and plastic contraptions that used a variety of pumping mechanisms, but none of these ...

European Journal of Physics, 2008
An experiment and a demonstration concerning transport by magnetic levitation (Maglev) are described. The lift, drag and radial forces on a magnet placed over a rotating conducting disc are measured versus the rotation frequency. The experiment relates to important topics of electromagnetism and could be a useful addition to the undergraduate physics ...

Transportation Research Part A: General, 1984
Abstract Magnetic levitation, or MAGLEV for short, is a technology that has had considerable effort expended on its development during the past 15 years. Although intended primarily for high-speed ground transportation, it has the potential for other applications.

Maglev (means magnetic + levitation) is a method of propulsion that uses magnetic levitation to propel vehicles with magnets rather than with wheels, axles, and bearings. With the Maglev, a vehicle is levitated a short distance away from a guideway by using magnets to create both lift and thrust.

The physical processes of control are investigational by a frontier layer on the profiled surface of the ground structure of perspective transport technologies. Conformities to law of influence of control parameters are set by a frontier layer on distribution of speeds on the ground structure.

Since the late 1970s, railways have made a comeback with the introduction of high-speed trains. Until then, railways had the image of being inefficient and trains had a speed of only 100-130 km/h. Nowadays trains can regularly achieve three times those speeds and national railway organisations feel the pressure for reorganisation to improve the quality
