Shanghai maglev is a very fast traffic tool, so it is very strict with the stability of the roadbed. However, the ground subsidence is a problem in Shanhai because of the poor geological condition and some human-induced factors. So it is necessary to monitor ground subsidence in the area along the Shanghai maglev precisely and frequently. Traditionally, precise levelling method is used to surve...

In order to solve the problems of lack of heart donors for transplant, implantable ventricular assist systems (VAS) have been developed to assist the failing heart ventricle. One of the components of a VAS is a blood pump that connects the left ventricle to the aorta. Therefore, the pump flow rate is influenced by the cardio-vascular system. To control the flow rate through the blood pump, real...

This work describes the development of magnetic levitation (MagLev) to characterize the kinetics of free-radical polymerization of water-insoluble, low-molecular-weight monomers that show a large change in density upon polymerization. Maglev measures density, and certain classes of monomers show a large change in density when monomers covalently join in polymer chains. MagLev characterized both...

This paper describes several noncontact methods of orienting objects in 3D space using Magnetic Levitation (MagLev). The methods use two permanent magnets arranged coaxially with like poles facing and a container containing a paramagnetic liquid in which the objects are suspended. Absent external forcing, objects levitating in the device adopt predictable static orientations; the orientation de...

In recent years, more and countries are paying attention to maglev transportation because of its outstanding advantages. However, the structure a train is complex than wheel-rail train, there no systematic theory method for kinematic modeling vehicle. Based on screw product exponentials (PoE) formula in field open-chain robotics, this paper presents mathematical analysis track. By analyzing cha...
