This paper presents a new approach applying this ECG particularity. A robust ECG Biometrics based on the features extraction with fiducial detection in the time domain is proposed.

However, interactions between early feeding and risk Juvenile idiopathic arthritis (JIA) remains largely unexplored. Objectives To determine the impact of early alimentation on the occurrence of JIA in Tunisia. Methods We conducted a case-control study including 26 children with JIA fulfilling the international league against rheumatism (ILAR) 2010 criteria compared with a homogeneous control group of 21 children hospitalized in a paediatric orthopedic unit for traumatic reasons and healthy for any chronic inflammatory rheumatism. Parents of patients were asked after having their consent to participate. We collected the following data: Type of JIA, juvenile disease activity score (JADAS), type of feeding, total duration of breastfeeding, duration of exclusive breastfeedi...

Their robust nature against tampering reduces the risk of fraud which makes 5 the security systems based on this signal quite reliable. For such purpose, the ECG is used as a 6 biomedical characteristic in the biometric system. This paper aims to improve the human 7 identification system by the use of fiducial points extracted from the ECG signal in the temporal 8 domain. For feature extraction step, a suitable set of features is considered; the latter consists in 9 the Morphological Descriptors (MD) and the Hermite polynomial expansion coefficients (HPEc). 10 Afterwards, these features are classified using multiclass Support Vector Machine (SVM) with 11 One-Against-One (OAO) and One-Against-All(OAA) approaches. The results stemming from 12 experiments show that the combination of all morphological descriptors with the coefficients of 13 expansion Hermite polynomials gives the best identification rate; which is equal to 96, 54%. 14
