Recently, a three-state model is presented to describe the intracellular traffic of unconventional (single-headed) kinesin KIF1A [Phys. Rev. Lett. 95, 118101 (2005)], in which each motor can bind strongly or weakly to its microtubule track, and each binding site of the track might be empty or occupied by one motor. As the usual two-state model, i.e. the totally asymmetric simple exclusion proce...

In present study, a mathematical model of the vehicle–floating slab track (FST) interaction is established to investigate the coupled behaviour of vehicle–track system. The FST is modelled as the double Euler -Bernoulli beam including the rail and slab. The railway vehicle is simplified as a multi-rigid-body model. The wheel–rail interface is treated using a nonlinear Hertzian contact model, co...

In magnetic disk drive actuators, the application of piezo electric material can be used to re ne and accomplish track following in (extremely) high track density magnetic data storage. In this paper the results on the modeling and control of a piezobased milli-actuator are presented. The modeling is done on the basis of a least squares curve tting of an estimated frequency response and taking ...

For the central tracking chamber of the JADE detector [l] at the e+estorage ring PETRA a new type of drift chamber, the so-called jet chamber, has been developed [Z-4]. This chamber is capable of recording events of high local track density (jets) with good space and double track resolution and with the possibility of particle identification within a solid angle close to ~I'I sterad. The concep...
