    The Multiplicative Inverse Eigenvalue Problem over an Algebraically Closed Field

    Full text link
    Let MM be a square matrix and let p(t)p(t) be a monic polynomial of degree nn. Let ZZ be a set of n×nn\times n matrices. The multiplicative inverse eigenvalue problem asks for the construction of a matrix in ZZ such that the product matrix MZMZ has characteristic polynomial p(t)p(t). In this paper we provide new necessary and sufficient conditions when ZZ is an affine variety over an algebraically closed field.Comment: 9 Page

    Radical and ion molecule mechanisms in the polymerization of hydrocarbons and chlorosilanes in RF plasmas at low pressures ( 1.0 torr)

    Get PDF
    The ion-molecule and the radical-molecule mechanisms are responsible for the dissociation of hydrocarbons, and chlorosilane monomers and the formation of polymerized species, respectively, in the plasma state of a RF discharge. In the plasma, of a mixture of monomer with Ar, the rate determining step for both dissociation and polymerization is governed by an ion-molecular type interaction. Additions of H2 or NH3 to the monomer Ar(+) mixture transforms the rate determining step from an ion-molecular interaction to a radical-molecule type interaction for both monomer dissociation and polymerization processes

    Homogeneous reactions of hydrocarbons, silane, and chlorosilanes in radiofrequency plasmas at low pressures

    The ion-molecule and radical-molecule mechanisms are responsible for the dissociation of hydrocarbon, silane, and chlorosilane monomers and the formation of polymerized species, respectively, in an RF plasma discharge. In a plasma containing a mixture of monomer and argon the rate-determining step for both dissociation and polymerization is governed by an ion-molecule type of interaction. Adding hydrogen or ammonia to the monomer-argon mixture transforms the rate-determining step from an ion-molecule interaction to a radical-molecule interaction for both monomer dissociation and polymerization

    Vibration Response of Railway Bridge Piers to Nearby Pile Driving

    In the development of a new highway system approaching Tel Aviv, Israel, long piles had to be driven very close to an existing railway bridge. In view of the danger of structural damage to the bridge, as a result of ground vibrations excited by the pile-driving work, field measurements were ordered. Vibrations recorded at the bridge pier heads in the course of the driving operation were analyzed and compared with those excited by trains. Results showed that the former are generally lower than the latter, and neither one exceeds the limits prescribed by the codes
