Exploratory Analysis of Scientific Publications for University Governance

open access: yesComputer Graphics Forum, Volume 44, Issue 6, September 2025.
This paper presents an exploratory system for the visual analysis of scientific publications for University governance. The application creates a 2D spatialisation of the publications of an institution, with an automatic clustering approach that groups papers in disciplines of research.

Structured Nuclear Norm Matrix Completion: Guaranteeing Exact Recovery via Block‐Column Scaling

open access: yesNumerical Linear Algebra with Applications, Volume 32, Issue 4, August 2025.
ABSTRACT The goal of low‐rank matrix completion is to minimize the rank of a matrix while adhering to the constraint that known (non‐missing) elements are fixed in the approximation. Minimizing rank is a difficult, non‐convex, NP‐hard problem, often addressed by substituting rank with the nuclear norm to achieve a convex relaxation.

Automated tool for cylindrical glass container blow and blow mold design

open access: yesInternational Journal of Applied Glass Science, Volume 16, Issue 3, July 2025.
Abstract The manufacture of perfumery bottles using the blow‐and‐blow technique necessitates iterative design and production of intermediate or preparation molds to achieve an appropriate thickness distribution. Designers seek a specific glass thickness at the bottle's bottom as an indicator of quality while ensuring a minimum thickness in the rest of ...
