Analytical Model for the computation of the drug administration dynamics and inlet pressures of an intravenous infusion system

Mostafa Brik, Souad Harmand, Mony Girault, Anne-Laure Metz, François Rochiccioli, Fabrice Lapeyre, Jérome Clarysse

In this paper, we have elaborated an analytical model to study the dynamics of the Smof-Lipid delivery in Neonate nutrition fluid with an Intravenous (IV) infusion system. For a simple configuration, containing two inlets and one outlet, used mainly in neonatology, analytical computations were...

Computational Reduction of Optimal Hybrid Vehicle Energy Management

Carlos Armenta, Sebastien Delprat, Rudy R Negenborn, Ali Haseltalab, Jimmy Lauber, Michel Dambrine

Pontryagin's Minimum Principle is a way of solving hybrid powertrain optimal energy management. This letter presents an improvement of a classical implementation. The core of this improvement consists in relaxing the tolerance on some intermediate steps of the algorithm in order to reduce the...

Fabrication and optimization of high frequency ZnO transducers for both longitudinal and shear emission: application of viscosity measurement using ultrasound

Hatem Dahmani, Ibrahim Zaaroura, Abbas Salhab, Pierre Campistron, Julien Carlier, Malika Toubal, Souad Harmand, V. Thomy, Marc Neyens, Bertrand Nongaillard

This paper covers the study of high-frequency (~ 1 GHz) ZnO piezoelectric transducer integrated on a silicon substrate able to generate both compressional and shear acoustic waves. First, to promote the longitudinal mode, an electrical matching of the transducer in this high-frequency range is...

Theoretical Investigations of Stirling Engine Performances for Different Working Fluids

Houda Hachem, Ramla Gheith, Fethi Aloui

The present paper is performed to investigate the effect of working fluids on a double-acting Stirling engine performance. A numerical model that includes major thermal losses that decrease the Stirling output power and efficiency was developed. The influences of tree monatomic gases (helium, Neon...

Spectral Analysis of LBM-LES Numerical Data on Lid-Driven Cavity

Insaf Mehrez, Ramla Gheith, Fethi Aloui

The lid-driven cavity is an important fluid mechanical system work for as a benchmark for testing numerical methods and for examining fundamental aspects of incompress- ible flows in confined volumes which are driven by the tangential motion of the bounding wall. A numerical study is provided of...

Heating Rate Effect on Tetrapak Paper Pyrolysis: Thermogravimetric Analysis

Afef Bouazizi, Emna Berrich, Imene Bekri, Ezzedine Srasra, Fethi Aloui

Biomass and plastics are considered to be one of the most important renewable sources in nature. The typical composition of a tetrapak is 70% of cardboard (Kraft paper), 25% of low-density polyethylene (LDPE), and 5% of aluminum foil. In this paper, we present the heat rate effect on tetrapak...

Parallel machine scheduling problem with a single server, Ordonnancement sur des machines parallèles avec un serveur partagé

Abdelhak El Idrissi

Scheduling is a discipline of combinatorial optimization. It aims to allocate a limited set of resources over time to a set of jobs to be scheduled, with the aim of optimizing one or more criteria (project duration, advances/delays, availability of machines, etc.). Scheduling on parallel machines..., L’ordonnancement est une discipline de l’optimisation combinatoire. Elle vise a` allouer dans le temps un ensemble limité de ressources a` des tâches a` réaliser, avec pour objectif d’optimiser un ou plusieurs critères (durée du projet, avances/retards, disponibilité des machines, etc). L’...

De nos jours les matériaux polymères sont omniprésents dans l’habitacle d’un véhicule. C’est le cas notamment pour les composants comme la planche de bord ou les panneaux de portes. Ces éléments sont soumis à des cahiers des charges imposés par les réglementations internationales pour minimiser les..., Nowadays, polymers are used for the interior parts of vehicles. It is particularly the case for components such as dashboards and door panels. These elements are submitted to requirements imposed by international regulations in order to minimize the injuries of the passengers in case of a car crash...
