    Vortex drop shaft structures have played a critical role in hydraulic engineering; from one of their first applications in hydroelectric energy dissipation in the 1940s, to numerous contemporary installations throughout modern ...
  • Mechanical properties estimation by non-destructive testing of Irish hardwood round timber from thinnings for construction purposes 

    Llana, Daniel F.; Short, Ian; O'Ceallaigh, Conan; Harte, Annette M. (Department of Forestry Policy and Economics, University of Sopron, Hungary, 2018-10-25)
    Thinning involves the removal of competitors of high quality trees, and trees for extraction racks, all to favour the growth of the selected trees. Many felled trees are small-diameter and in Ireland hardwood thinnings are ...
  • Observed installation effects of vibro-replacement stone columns in soft clay 

    Egan, D.; Scott, W.; McCabe, Bryan A. (National University of Ireland Galway, 2008-09-03)
    The installation of vibro replacement stone columns in any soil causes significant changes to the stress regime around each probe location. In soft clays, the principal effects are caused by a cavity expansion mechanism ...
  • Is geotechnical education meeting industry demands? The Irish position 

    McCabe, Bryan A.; Phillips, D. T. (National University of Ireland Galway, 2008-06-02)
    This paper presents the results of a survey carried out in late 2007 to gauge how geoengineering education is perceived to meet the demands of Irish industry. The survey was internet-based and the responses provide some ...
