Fourier-based contour descriptors to relax positional standardization of the otolith images in AFORO queries

open access: yesScientia Marina, 2020
The otolith digital catalogue AFORO allows unknown otoliths to be classified automatically by using a comparison with its classified records. To do this, the otolith’s contour, which is extracted from an image, is used.

Sagitta, Lenses, and Maximal Volume [PDF]

open access: yesThe Journal of Geometric Analysis, 2015
We give a characterization of critical points that allows us to define a metric invariant on all Riemannian manifolds $M$ with a lower sectional curvature bound and an upper radius bound. We show there is a uniform upper volume bound for all such manifolds with an upper bound on this invariant.

Enhanced Mechanical and Shape Memory Properties of Laser Direct Energy Deposited CoCrFeMn High Entropy Alloy by Carbon Addition

open access: yesAdvanced Engineering Materials, Volume 27, Issue 22, November 2025.
Feasibility of improving the mechanical and shape‐memory properties of a CoCrFeMn high‐entropy alloy through carbon addition is investigated. The recovery strain of the carbon‐containing alloy is approximately four to five times higher than that of the carbon‐free alloy.
