Aging and Numerosity Estimation [PDF]

open access: yesThe Journals of Gerontology: Series B, 2007
Abstract In two experiments, young and older participants were asked to find the approximate number of dots in collections including between 40 and 460 dots. Experiment 1 showed that both age groups had comparable performance and no age-related differences in the power-function exponents for numerosity.

Determining the Age Range Based on Machine-Learning Methods From Facial Skeletal Angles (Glabella and Maxilla Angle and Length and Width of Piriformis) in CT Scan

open access: yesInternational Journal of Medical Toxicology and Forensic Medicine, 2022
Background: One of the main steps in identifying a person in forensic medicine is determining the age of skeletal remains, including the skull. This study aimed to investigate the possibility of predicting age from facial angles (glabella, piriformis ...

The Sun, stellar-population models, and the age estimation of high-redshift galaxies [PDF]

open access: yes, 2000
Given sufficiently deep optical spectroscopy, the age estimation of high-redshif t ($z > 1$) galaxies has been claimed to be a relatively robust process (e.g. Dunlop et al.

Accuracy of Age Estimation Using Three Dental Age Estimation Methods in a Young, Large, and Multiethnic Patient Sample

open access: yesDentistry Journal, 2023
European countries have become host countries for migrants and unaccompanied minors. However, many migrants arrive without identity documents. Many methods exist to estimate age; among them, several methods using dental age have been proposed.

Star Cluster Evolution, Dynamical Age Estimation and the Kinematical Signature of Star Formation [PDF]

open access: yes, 1995
We use N-body integration to follow the evolution of clusters of 200 binary systems with different initial half mass radii $R_{0.5}$. We also simulate single-star clusters.

Hybrid Ageing Patterns for face age estimation [PDF]

open access: yesImage and Vision Computing, 2018
Abstract Wrinkles can be embedded in several image-based applications as a descriptor for human skin. However, wrinkle-based age estimation research has not been widely addressed. In this paper, we introduce a Multi-scale Wrinkle Patterns (MWP) representation, investigate the effect of wrinkles on face age estimation and propose Hybrid Ageing ...
