Simulation and Optimization of an Airfoil with Leading Edge Slat
Journal of Physics: Conference Series, 2016 A gradient-based optimization is used in order to improve the shape of a leading edge slat upstream of a DU 91-W2-250 airfoil. The simulations are performed by solving the Reynolds-Averaged Navier-Stokes equations (RANS) using the open source CFD code OpenFOAM.

Multi-Objective Numerical Optimization Applied to Aircraft Design
, 2008 Aircraft design is a very complex process because several disciplines are involved at the same time: aerodynamics, structures, performances, propulsion, costs. From this point of view, the real aircraft is a compromise between several requirements, often

Statistics in Medicine, Volume 45, Issue 13-14, June 2026.ABSTRACT Although homoscedasticity is often assumed in linear regression, real data may show variance patterns or residual structures that violate this assumption. We propose VarGuid, a variance‐guided framework for two related settings: Covariate‐dependent conditional variance under a global linear mean model, and residual nonlinear mean structure ...

Multiobjective optimization using surrogates
, 2006 Until recently, optimization was regarded as a discipline of rather theoretical interest, with limited real-life applicability due to the comutational or experimental expense involved.
