Particle Swarm Optimization Of Fuzzy Penalty For 3D Image Reconstruction In X-Ray Tomography

Mohamed Tahar Ali Gouicem, Mostepha Yahi, Abdelmalik Taleb-Ahmed, Redouane Drai

Engineers last year's works only on the 2D image data, to perceive defects in the CT images. This was a handicap facing the challenge of determining the 3D exact defect form. This paper presents a method for 3D image reconstruction, the most interesting in non destructive testing (NDT)...

The Golden hour challenge, applying systems engineering to life critical system of systems

Jean-René Ruault

Road accidents are at the origin of numerous casualties. One of the initiatives consists of taking care of the wounded persons as soon as possible, respecting the "golden hour" rule. This rule prescribes that the earlier the wounded persons are taken care of, the less grave the after...

Risk management in Life Critical Systems

Patrick Millot

Risk management deals with prevention, decision-making, action taking, crisis management and recovery, taking into account the consequences of unexpected events. The authors of this book are interested in ecological processes, human behavior, as well as the control and management of life-critical...

A nonmonotonically decreasing relaxation approach of Lyapunov functions to guaranteed cost control for discrete fuzzy systems

Kohei Inoue, Ying-Jen Chen, Thierry-Marie Guerra, Hiroshi Ohtake, Hua O. Wang, Motoyasu Tanaka, Alexandre Kruszewski, Kazuo Tanaka

This study presents a nonmonotonically decreasing relaxation approach of Lyapunov functions to guaranteed cost control for discrete Takagi–Sugeno (T–S) fuzzy systems. First, the authors summarise the previous results on a relaxation of nonmonotonically decreasing of Lyapunov functions, and newly...

Vers la résilience des services d'urgences hospitalières : gestion efficace des situations de tension

Farid Kadri, Sondès Chaabane, Christian Tahon

RESUME : Face aux menaces et événements exceptionnels (crises sanitaires liées à des épidémies, grippes, canicules, vagues de froid, qui sont en évolution continues.) pesant sur les établissements hospitaliers, en particulier les services d'urgences, la gestion efficace de ces événements est...

A DATA MINING-BASED APPROACH TO PREDICT STRAIN SITUATIONS IN HOSPITAL EMERGENCY DEPARTMENT SYSTEMS

Sofia Benbelkacem, Farid Kadri, Sondès Chaabane, Baghdad Atmani

Nowadays, emergency departments are confronted to exceptional events such as epidemics problems or health crises. These situations increase the patient flow. The consequence of this influx of patients has resulted in problems of ED overcrowding which often increases the length of stay of patients (...

PREDICTING HOSPITAL LENGTH OF STAY USING REGRESSION MODELS: APPLICATION TO EMERGENCY DEPARTMENT

Catherine Combes, Farid Kadri, Sondès Chaabane

Increasing healthcare costs motivate the search for ways to increase care efficiency. In this paper, we present a novel methodological framework based on predictive data mining approach to estimate the LOS (Length Of Stay) in an emergency department (ED). We use supervised learning that the goal is...

New stabilization conditions for continuous fuzzy models using their discretized forms

Ameni Ellouze, Mohamed Ksantini, Jimmy Lauber, François Delmotte, Mohamed Chtourou

Purpose – The purpose of this paper is to deal with the stabilization of the continuous-time Takagi-Sugeno (TS) fuzzy models by using their discretized models. Design/methodology/approach – In this case, a discrete model is obtained from the discretization of the continuous TS fuzzy model. The...

Multiscale assessment of the accuracy of surface replication

Julie Marteau, M Wieczorowski, Y Xia, Maxence Bigerelle

This paper presents a methodology for the assessment of replication accuracy using a multiscale approach. It focuses on the quantification of 'metrological replication accuracy', which is a direct comparison of the topography of a surface and its replica. This methodology uses an analysis...

Joint semi-blind estimation of CFO and channel for OFDM system

Mokhtar Besseghier, Ahmed Bouzidi Djebbar, Iyad Dayoub, Abdelmalik Taleb-Ahmed

The greatest threat to the OFDM system is the loss of orthogonality between subcarriers due to the carrier frequency offset (CFO) which results in significant performance degradation. In addition to this last problem was the effect of propagation over multipath fading channel. Hence, both the...
