To solve the best-fit sphere (BFS) accurately is one of the technological keys for the generating and testing of optical aspherical surfaces. This paper presents a new algorithm for solving the BFS of aspherical surfaces to suppress some deficiencies in the existing BFS algorithms. In the proposed approach  it is not only suitable for the conic surface  a BFS is constructed  but also for higher order aspheres. The obtained asphericity and material removal function is more suitable for the machining and test. (2012) Trans Tech Publications  which passes through both sides of endpoints in the section o -?xy of the aspherical surfaces  Switzerland.  the center of the BFS is shifted along the x-axis  and its radius of curvature is automatically computed. The variable step size method is proposed to speed up the convergence of the iteration. Through numerically solving the BFS of conic and cubic surface  the advantages of the proposed approach are verified. The results show that the proposed approach is of rapid convergence  and high accuracy

Solitary kinetic Alfven waves in dusty plasmas are studied by Considering the dust charge variation. The effect of the dust charge-to-mass ratio on the soliton solution is discussed. The Sagdeev potential is derived analytically with constant dust charge and then calculated numerically by taking the dust charge variation into account. We show that the dust charge-to-mass ratio plays an important role in the soliton properties. The soliton solutions are comprised of two branches. One branch is sub-Alfvenic and the soliton velocity is obviously smaller than the Alfven speed. The other branch is super-Alfvenic and the soliton velocity is very close to or greater than the Alfven speed. Both compressive and rarefactive solitons can exist. For the sub-Alfvenic branch  the rarefactive soliton is bell-shaped and it is much narrower than the compressive one. However  for the super-Alfvenic branch  the compressive soliton is bell-shaped and narrower  and the rarefactive one is broadened. When the charge-to-mass ratio of the dust grains is sufficiently high  the width of the rarefactive soliton  in the super-Alfvenic branch  will broaden extremely and a electron depletion will be observed. It is also shown that the bell-shaped soliton can transition to a cusped structure when the velocity is sufficiently high. (C) 2008 American Institute of Physics.
