We describe an application of nonlinear optimization in interferometric optical astronomy. The aim is to find the relative positions of the output pupils and the modulus of the beams through each pupil of a linear array of telescopes in order to design an instrument capable of imaging...

The aim of this paper is to characterize in terms of classical convexity and quasiconvexity of extended real-valued functions those set-valued maps which are K-convex or K-quasiconvex with respect to a convex cone K. In particular, we recover some known characterizations of K-convex and...

This paper provides a global, transparent and dynamic decision support tool that clusters listed banks depending on their riskiness using an unsupervised learning algorithm. This entirely automatic process is updated weekly on a dedicated website, and refreshable on-demand. A large set of...
