  • Site occupancy of chlorine on Cu(111) using normalincidence xray standing waves The energy difference between fcc and hcp hollow sites 
    Shard Alex; Ton-That Cuong; Campbell P; Dhanak Vinod (American Physical Society, 2004)
    It has previously been established that the lowest energy site for chlorine atoms on Cus111d is the “fcc” hollow. However, substantial population of the “hcp” hollow at room temperature indicates that there is a relatively ...
  • The 1s-State Analysis Applied to High-Angle, Annular Dark-Field Image Interpretation: When Can We Use It? 
    Anstis Geoffrey (Cambridge University Press, 2004)
    A small probe centered on an atomic column excites the bound and unbound states of the two-dimensional projected potential of the column. It has been argued that, even when several states are excited, only the 1s state ...

  • Coupled dipole method for scatterers with large permittivity 
    Chaumet Patrick; Sentenac Anne; Rahmani Adel (American Physical Society, 2004)
    In the coupled dipole method, a three-dimensional scattering object is discretized over a lattice into a set of polarizable units that are coupled self-consistently. Starting from the volume integral equation for the ...
  • Dynamic Modelling and Applications for Passenger Car Powertrains 
    Crowther Ashley; Zhang Nong (Australian Acoustical Society, 2004)
    Torsional finite elements for direct, geared, branched and grounded connections are presented. For a simple three-degreesof- freedom powertrain model the finite elements are defmed and the global system assembly is detailed. ...
  • Ab initio study of benzene adsorption on the Cu(1 1 0) surface and simulation of STM images 
    Rogers B; Shapter Joe G; Ford Michael (Elsevier Science, 2004)
    The adsorption of benzene molecules onto the Cu(110) surface has been studied using a crystalline linear combination of atomic orbitals approximation (LCAO). Adsorption energetics have been modeled at both the Hartree-Fock ...
  • Development of a slotless tubular linear interior permanent magnet micromotor for robotic applications 
    Lu Haiwei; Zhu Jianguo; Guo Youguang (Institute of Electrical and Electronics Engineers, 2005)
    Linear micromotors play a key role in microrobotic systems. They can greatly simplify the drive mechanisms, which is crucial for microsystems. By using permanent magnets, much higher force-to-volume ratio can be obtained ...
