Impact of the lossy image compression on the biometric system accuracy: a case study of hand biometrics

Djamel Samai, Abdallah Meraoumia, Mouldi Bedda, Abdelmalik Taleb-Ahmed

Biometric recognition systems are used in several cases, to recognise people using images. Storing of large images require large storage space. To reduce the storage space, compression methods are employed. In this paper, we analyse the effect of lossy image compression on the performance of…

Every centroaffine Tchebychev hyperovaloid is ellipsoid

Xiuxiu Cheng, Zejun Hu, Luc Vrancken

We study locally strongly convex Tchebychev hypersurfaces, namely the centroaffine totally umbilical hypersurfaces, in the (n+1)-dimensional affine space Rn+1. We first make an ordinary-looking observation that such hypersurfaces are characterized by having a Riemannian structure admitting a…

Submental Anatomical Variations: The Uniqueness of a Common Variation

Laísa Caldas Fernandes, Patricia Shirley de Almeida Prado

Introduction: submental region is subject to many variations, predominantly affecting the anterior belly of the digastric muscle. The medical importance of this area led us to compile a database with the reported cases of the anomalous belly of the anterior belly of the digastric muscle as well as…

Qualitative and Quantitative Analyses of Surface Alterations of Stone Tools Made of Raw Materials from the Carpathian Basin

Antony Borel, Raphaël Deltombe, Julie Marteau, Philippe Moreau, Maxence Bigerelle, György Lengyel, Zsolt Mester

Wear analysis performed on archaeological stone tools from prehistory aims at characterizing their surface alterations in order to determine their functions and describe past human technical behaviors. However, the reliability and repeatability of the method is questioned and there is a major…

Generating new classes of fixed-time stable systems with predefined upper bound for the settling time

Rodrigo Aldana-Lopez, David Gomez-Gutierrez, Esteban Jiménez-Rodríguez, Juan Diego Sanchez-Torres, Michael Defoort

This paper aims to provide a methodology for generating autonomous and non-autonomous systems with a fixed-time stable equilibrium point where an Upper Bound of the Settling Time (UBST) is set a priori as a parameter of the system. Furthermore, some conditions for such an upper bound to be the…

Affine hypersurfaces with constant sectional curvature

Miroslava Antić, Haizhong Li, Luc Vrancken, Xianfeng Wang

We use a new approach to study locally strongly convex hypersurfaces with constant sectional curvature in the affine space (Formula presented). We prove a nice relation involving the eigenvalues of the shape operator S and the difference tensor K of the affine hypersurface. This is achieved by…

Adaptative vital signs monitoring system based on the early warning score approach in smart hospital context

Imen Ben Ida, Moez Balti, Sondès Chaabane, Abderrazak Jemai

Changes in vital signs are an important indicator of physiological decline and provide opportunities for early recognition and intervention. The collected vital signs data can be evaluated using several approaches such as the Early warning score (EWS) approach to predict the risk level of patients…
