Using Machine Learning Models to Predict the Length of Stay in a Hospital Setting

Rachda Naila Mekhaldi, Patrice Caulier, Sondès Chaabane, Abdelahad Chraibi, Sylvain Piechowiak

Proper prediction of Length Of Stay (LOS) has become increasingly important these years. The LOS prediction provides better services, managing hospital resources and controls their costs. In this paper, we implemented and compared two Machine Learning (ML) methods, the Random Forest (RF) and the…

Optimal model-free backstepping control for a quadrotor helicopter

Hossam Eddine Glida, Latifa Abdou, Abdelghani Chelihi, Chouki Sentouh, Seif-El-Islam Hasseni

This paper proposes a design of a direct optimal control for a class of multi-input–multi-output (MIMO) nonlinear systems. This work focuses on the design of optimal model-free backstepping controller for a MIMO quadrotor helicopter perturbed by unknown external disturbances. The proposed method…

Deep Random Forest for Facial Age Estimation Based on Face Images

Oussama Guehairia, Abdelmalik Ouamane, Fadi Dornaika, Abdelmalik Taleb-Ahmed

The face image of an individual is important for most biometrics systems. The face picture gives loads of helpful informations, including the individual's personal identity, gender, ethnicity, age, emotional expression, and so forth. As of late, a few applications that endeavor age estimation…

Finger-Knuckle-Print Recognition Using Deep Convolutional Neural Network

Selma Trabelsi, Djamel Samai, Abdallah Meraoumia, Khaled Bensid, Azeddine Benlamoudi, Fadi Dornaika, Abdelmalik Taleb-Ahmed

Biometric technology has become essential in our daily life. In such a biometric system, personal identification is based on behavioral or biological characteristics. Recently, the trait of the Finger-Knuckle-Print (FKP) is used due to its ease of use and low cost. In order to develop an efficient…

La valorisation du personnel au sein des PME belges

Claire Dupont, Perrine Ferauge, Isabelle Alphonse-Tilloy, Sylvie Scoyez van Poppel

The aim of our paper is to study staff development in belgian SMEs. We want to analyse if the way entrepreneur views HRM can affect staff development policy. Thanks to quantitative data from 159 belgian entrepreneurs, we distinguish 3 types of entrepreneurs that do not share the same view about…, Notre recherche s’intéresse à l’existence d’une politique de valorisation du personnel au sein de PME belges et à l’influence de la vision de la GRH développée par leur dirigeant dans l’implémentation d’une telle politique. Les informations fournies par 159 dirigeants de PME belges ayant répondu à…

Evaporation of a sessile oil drop in the Wenzel-like regime

Dorra Khilifi, Walid Foudhil, Souad Harmand, Sadok Ben Jabrallah

In this work, we present an experimental study of the evaporation of oil drops deposited on both textured and smooth silicon substrates at two different temperatures (20 °C and 270 °C). We show that the sessile drops take a hexagonal form and are linked by an oil film (a droplet sitting on a…

A BIM-based method to plan indoor paths

Ahmed Hamieh, Aicha Ben Makhlouf, Borhen Louhichi, Dominique Deneux

Humans more and more live in urban areas and spend the majority of their time indoors, while buildings are becoming increasingly interconnected. Path planning in complex indoor environments is consequently becoming a societal challenge. This paper proposes a system, called BiMov, dedicated to…

Experimental Study of the Effect of Water Spray in the Air on Thermal Transfers Along a Plate of an Exchanger

Nihel Grich, Walid Foudhil, Souad Harmand, Sadok Ben Jabrallah

This study is an experimental investigation of the oceanic environment effect on a plate heat exchanger performance. Indeed, an experiment was carried out on a single plate of the exchanger to generate a turbulent airflow in which fine water droplets were injected into a horizontal vein where a…
