Coleman-free aero-elastic stability methods for three- and two-bladed floating wind turbines by B. Pamfil, H. Bredmose, T. Kim

“…The Coleman transform is not directly valid for the stability analysis of two-bladed floating wind turbines without applying an additional method to eliminate the system matrix time dependence. Therefore, here we pursue methods that do not rely on it. …”

Finite element analysis of chloride ion penetration and service life prediction in concrete with supplementary cementitious materials by Pooria Dashti, Faramarz Moodi, Ali Akbar Ramezanianpour, Rasoul Banar

“…SCMs significantly reduced chloride penetration in both w/b ratios; SF-containing concrete achieved the lowest diffusion coefficient (1.563 × 10⁻¹² m²/s at 12 months), due to its ability to densify the concrete matrix. Time-dependent diffusion modelling improved SL prediction accuracy, reducing simulation errors to below 30%, compared to 48–75% for constant models. …”
