  • searches for lepton flavor violation in the decays tau e gamma and tau mu gamma
    Physical Review Letters, 2010
    Co-Authors: Y Karyotakis, J P Lees, V Poireau, E Prencipe, X Prude, V Tisserand, Garra J Tico, E Grauges, M Martinelli, A Palano
    Abstract:

    Searches for lepton-flavor-violating decays of a tau lepton to a lighter mass lepton and a photon have been performed with the Entire Data Set of (963 +/- 7) x 10(6) tau decays collected by the BABAR detector near the Y(4S), Y(3S) and Y(2S) resonances. The searches yield no evidence of signals and we Set upper limits on the branching fractions of B(tau(+/-) -> e(+/-)gamma) mu(+/-)gamma) < 4.4 X 10(-8) at 90% confidence level.

  • Wetland vegetation of southern KwaZulu-Natal, South Africa
    Bothalia, 2000
    Co-Authors: L. Perkins, G.j. Bredenkamp, J. E. Granger
    Abstract:

    Vegetation Data from southern KwaZulu-Natal were analysed. TWINSPAN classification separated the Entire Data Set (547 releves) into five subSets. One subSet, representing the vegetation of the wetlands of southern Kw aZulu-Natal, was further classified by Braun-Blanquet procedures. Eight plant communities and fourteen subcommunities were identified and described. The results can be integrated with existing phytosociological classifications of the Grassland Biome.

  • The phytosociology of the incised river valleys and dry upland savanna of southern KwaZulu-Natal
    South African Journal of Botany, 1999
    Co-Authors: L. Perkins, G.j. Bredenkamp, J.e. Grange
    Abstract:

    Vegetation Data from southern KwaZulu-Natal were analysed. TWINSPAN classification separated the Entire Data Set (547 releves) into five subSets, One subSet, representing the vegetation of the incised river valleys and dry upland savanna of southern KwaZulu-Natal, was further classified by Braun-Blanquet procedures. Five plant communities and nine sub-communities were identified and described. The results can be integrated with existing phytosociological classifications of the Grassland Biome.

  • model development for the wideband expressway vehicle to vehicle 2 4 ghz channel
    Wireless Communications and Networking Conference, 2006
    Co-Authors: G Acosta, M A Ingram
    Abstract:

    Statistical channel models for small-scale fading are presented for a frequency selective vehicle-to-vehicle or mobile-to-mobile wireless communications link in an expressway environment in Atlanta, Georgia, where both vehicles travel in the same direction. These doubly selective models were developed from measurements taken using the direct sequence spread spectrum (DSSS) technique at 2.45 GHz. The models imply a non-separable channel with a persistent Ricean behavior across multiple model taps. We also explore model dynamics by comparing BER statistics for an overall model that is fit to the Entire Data Set with those of a collection of models, each fit to smaller, non-overlapping intervals
