Surface-based technologies and the settlement of Mytilus galloprovincialis [PDF]

, 2012
The mussel Mytilus galloprovincialis is a common aquaculture species, and also a major fouling organism that has negative economic impacts. There are no standard assay conditions for this important species and therefore the initial study of this thesis (Chapter 2) quantified the effect of key factors on the settlement of pediveligers and plantigrades ...

Analysis of ground surface settlement in anisotropic clays using XGBoost and RFR models

Journal of Rock Mechanics and Geotechnical Engineering, 2021
Excessive ground surface settlement induced by pit excavation (i.e. braced excavation) can potentially result in damage to the nearby buildings and facilities. In this paper, extensive finite element analyses have been carried out to evaluate the effects
