The first consistent and reproducible evaluation of the effect of aging on dynamic signature is reported. Experiments are carried out on a database generated from two previous datasets which were acquired, under very similar conditions, in 6 sessions distributed in a 15-month time span. Three different systems, representing the current most popular approaches in signature recognition, are used ...

In a population of 432 apparently healthy men aged 50 years and over 19-2% had one or more erythrocytes per high-power field in the urine while 8-1% had more than 10. Erythrocyturia seemed to be strongly correlated with tobacco consumption. No significant association with occupation could be demonstrated but the data were insufficient to refute the possibility of such an association. Raised lev...

This paper illustrates the use of biometrics through the application of an iris-based biometrics system for identifying twins and their parents in a longitudinal research study. It explores the use of biometrics (science of measuring physical or anatomical characteristics of individuals) as a technology for correct identification of individuals during longitudinal studies to help ensure data fi...
