On martingale approximations and the quenched weak invariance principle [PDF]

open access: yes, 2012
In this paper, we obtain sufficient conditions in terms of projective criteria under which the partial sums of a stationary process with values in ${\mathcal{H}}$ (a real and separable Hilbert space) admits an approximation, in ${\mathbb{L}}^p({\mathcal ...

A Space Industry Ontology Suite

open access: yes, 2023
This use case develops a set of ontologies (and related systems) for space industry: astronautics and astronomy related, with conceptual, philosophical and formal ontological exploration: spatiality and spatio-temporality, causality, discipline-specific questions. It develops top-level and mid-level space domain reference models.
