Hydrodynamic Hull Form Design Using an Optimization Technique [PDF]
Abstract A design procedure for a ship with minimum resistance had been developed using a numerical op-timization method called SQP (Sequential Quadratic Programming) combined with computational fluid dynamics (CFD) technique. The frictional resistance coefficient was estimated by the ITTC 1957 model-ship correlation line formula and the wave-making ...

Semidefinite descriptions of the convex hull of rotation matrices [PDF]
We study the convex hull of $SO(n)$, thought of as the set of $n\times n$ orthogonal matrices with unit determinant, from the point of view of semidefinite programming. We show that the convex hull of $SO(n)$ is doubly spectrahedral, i.e. both it and its
