NUMERICAL PREDICTION OF HYDROFOIL PERFORMANCE IN WAVE BY NURBS NUMERICAL WAVE TANK

Transactions of FAMENA, 2015
Time domain simulation using a Mixed Eulerian-Lagrangian (MEL) formulation and a high-order boundary integral method based on the Non-Uniform Rational B-spline (NURBS) formulation is employed to develop a Numerical Wave Tank (NWT). At each time step the Laplace equation is solved in the Eulerian frame and fully nonlinear free surface conditions are ...

The EU's Strategy for Sustainability: A Landmark Turn With the European Green Deal?

European Policy Analysis, EarlyView.
ABSTRACT While the European Green Deal (EGD) has been widely recognized as a milestone in the EU's sustainability strategy, scholars disagree on the nature of the policy change it represents. Critics highlight its limited social and environmental ambitions, despite its portrayal as a “man on the moon” moment.

Subspace Acceleration for Efficient Nonlinear Water Wave Simulation

International Journal for Numerical Methods in Fluids, EarlyView.
We introduce an exponentially weighted subspace acceleration technique to reduce GMRES iterations for solving the Poisson equation with time‐dependent coefficients in nonlinear, dispersive free‐surface flows governed by the incompressible Navier‐Stokes equations. The method significantly reduces memory requirements and computational complexity compared

Obstetrics and gynecology devices designed for low‐ and middle‐income countries: A narrative review

International Journal of Gynecology &Obstetrics, Volume 169, Issue 1, Page 71-80, April 2025.
Abstract There are many barriers contributing to poor health outcomes for women in low‐ and middle‐income countries (LMICs), one of which is the lack of necessary medical devices. Presently, the development of various kinds of devices intended to improve women's health outcomes specifically in LMICs remains underrepresented in the literature; therefore,
