Insights Into the Mechanisms Controlling the Residual Strength of Bio‐cemented Sands
International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.ABSTRACT Microbially induced carbonate precipitation (MICP) is an emerging technique for enhancing the mechanical properties of granular soils. Although several experimental studies have reported increased shear strength in MICP‐treated soils at both peak and residual states, other findings have shown reductions in residual strength compared to ...

Wind Energy, EarlyView.ABSTRACT The installed wind energy capacity increases every year. However, operation and maintenance costs still make up a considerable portion of the levelized costs of electricity. This costs can be greatly reduced by the application of suitable early fault detection methods. The supervisory control and data acquisition system of wind turbines is one

Wave–current–wind interaction with elastic floating offshore wind turbines
Engineering Analysis with Boundary ElementsThis study is concerned with rigid-body responses and elastic motion offloating offshore wind turbines (FOWTs) under combined wave, current and wind loads. A numerical approach is developed in frequency domain based on the linear diffraction theory with a Green function for small current speeds and the blade-element momentum method for hydrodynamic and
