Non-Binary Parallel Turbo LDPC Codes Associated with High Order Constellation

Latifa Mostari, Abdelmalik Taleb-Ahmed, Abdennacer Bounoua

Since the non-binary LDPC (Low-Density Parity-Check) codes offer better performance than binary LDPC codes for a system using high order constellations such as the QAM (Quadrature Amplitude Modulation), one proposes in this paper a high non-binary LDPC code, called a parallel nonbinary turbo LDPC…

#Coronamaisons : confinement sur les réseaux sociaux

Caroline Soreau

Mars 2020. La France se confine. Le monde extérieur semble s’arrêter ; le temps ralentir considérablement. Nous devons rester chez nous ; sauver le monde depuis notre canapé. Drôle de guerre. Le bouleversement de notre quotidien provoque l’inquiétude, l’angoisse, voire la paranoïa. Parallèlement,…, March 2020. France is on lockdown. The outside world seems to stop ; time is slowing down considerably. We must stay at home ; save the world from our couch. Phony War. The upheaval in our daily lives causes worry, anguish and even paranoia. At the same time, we are observing a real burst of…

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…

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…

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…

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).
