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…

A comparative study between compressive sensing and conventional speech conding methods

Abdelkader Boukhobza, Messaoud Hettiri, Abdelmalik Taleb-Ahmed, Abdennacer Bounoua

Speech coding is an essential procedure in public switched telephone system (PSTN), digital cellular communications, videoconferencing systems, and emerging voice over Internet applications. Compressed sensing is an original signal processing tool for efficiently acquiring and reconstructing a…

In vivo damage study of different textured breast implants

Charles Garabedian, Romain Vayron, Nathalie Bricout, Raphaël Deltombe, Karine Anselme, Maxence Bigerelle

Certain types of breast implant texture present increased risks of anaplastic large cell lymphoma (ALCL), which results from a chronic inflammatory process. Silicone debris released from implant surfaces upon wear might be implicated in this inflammation. However, in vivo formation of such debris…

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…

A review on potentials of coupling PCM storage modules to heat pipes and heat pumps

Saman Rashidi, Hamid Shamsabadi, Javad Abolfazli Esfahani, Souad Harmand

A large portion of world’s final energy consumption is employed in thermal form. The proper techniques can be used to improve the efficiencies of thermal energy systems and decrease the energy consumption. Phase change material (PCM) storage modules can be coupled with different thermal systems to…

Thermal control of electronic components using a liquid around the phase change material

Haythem Shili, Kamel Fahem, Souad Harmand, Sadok Ben Jabrallah

As part of the research in the field of thermal control of electronic components, we confined a phase change material (plastic paraffin) in a liquid and we heated it on one vertical side by a hot plate. The presence of the liquid around the phase change material (PCM) prevents the direct contact…

A class of predefined-time controllers for uncertain second-order systems

Juan Diego Sanchez-Torres, Aldo-Jonathan Muñoz-Vázquez, Michael Defoort, Esteban Jiménez-Rodríguez, Alexander Loukianov

This paper proposes a novel formulation for robust predefined-time stabilisation of a class of second-order systems with matched perturbations. The presented approach allows designing a family of controllers that enforce a predefined-time sliding motion, even in the presence of unknown but bounded…
