    Matching the High Momentum Modes in a Truncated Determinant Algorithm

    Get PDF
    Within a truncated determinant algorithm, two alternatives are discussed for including systematically the remaining ultraviolet modes. Evidence is presented that these modes are accurately described by an effective action involving only small Wilson loops.Comment: LATTICE98(algorithms) ; typos correcte

    SWECS tower dynamics analysis methods and results

    Get PDF
    Several different tower dynamics analysis methods and computer codes were used to determine the natural frequencies and mode shapes of both guyed and freestanding wind turbine towers. These analysis methods are described and the results for two types of towers, a guyed tower and a freestanding tower, are shown. The advantages and disadvantages in the use of and the accuracy of each method are also described

    Numerical Evidence for the Observation of a Scalar Glueball

    Get PDF
    We compute from lattice QCD in the valence (quenched) approximation the partial decay widths of the lightest scalar glueball to pairs of pseudoscalar quark-antiquark states. These predictions and values obtained earlier for the scalar glueball's mass are in good agreement with the observed properties of fJ(1710)f_J(1710) and inconsistent with all other observed meson resonances.Comment: 12 pages of Latex, 3 PostsScript figures as separate uufil

    Using The Major Field Test-Business As An Assessment Tool And Impetus For Program Improvement: Fifteen Years Of Experience At Virginia Military Institute

    Get PDF
    We examine the history of VMI’s use of the Major Field Test as an assessment tool for its Department of Economics and Business.  Further, we chronicle how the information gathered from a decade and a half of use has shaped the curriculum, faculty composition and policies within the Department. There is evidence that the policies surrounding how and when the Major Field Test is administered influences student performance on the test and that it can be a valuable component of a comprehensive assessment program. &nbsp

    Meson Decay Constants from the Valence Approximation to Lattice QCD

    We evaluate fπ/mρf_{\pi}/ m_{\rho}, fK/mρf_K/ m_{\rho}, 1/fρ1/f_{\rho}, and mϕ/(fϕmρ) m_{\phi}/(f_{\phi} m_{\rho}), extrapolated to physical quark mass, zero lattice spacing and infinite volume, for lattice QCD with Wilson quarks in the valence (quenched) approximation. The predicted ratios differ from experiment by amounts ranging from 12\% to 17\% equivalent to between 0.9 and 2.8 times the corresponding statistical uncertainties.Comment: uufiles encoded copy of 40 page Latex article, including 14 figures in Postscript.

    The scalar and tensor glueballs in the valence approximation

    Full text link
    We evaluate the infinite volume, continuum limit of 0++0^{++} and 2++2^{++} glueball masses in the valence approximation. We find m0++=1740±71m_{0^{++}} = 1740 \pm 71 ~MeV and m2++=2359±128m_{2^{++}} = 2359 \pm 128 ~MeV, consistent with the interpretation of f0(1710)f_0 ( 1710 ) as the lightest scalar glueball.Comment: (talk presented by A. Vaccarino at Lattice 93) 3 pages of PostScript in uufiles compressed form. IBM-HET-94-
