Investigation of the performance of modified TCM scheme for the protection of SPIHT-based compressed images over fading channel

Mohamed Ben Aissa, Abdesselam Bassou, Mohammed Beladgham, Abdelmalik Taleb-Ahmed, Abdelmounaim Moulay Lakhdar

In this paper, a new variant of trellis-coded modulation with Ungerboeck-Gray mapping 'TCM-UGM' is presented for spectral efficiency of 2 bit/s/Hz. The performance of this encoding scheme is investigated over Rayleigh fading channel. The simulation result, using 16-state TCM-UGM encoder,…

Liquid hydrocarbon fuels from fish oil industrial residues by catalytic cracking

Nadia Mrad, Maria Paraschiv, Fethi Aloui, Edwin Geo Varuvel, Mohand Tazerout, Sassi Ben Nasrallah

In the present work, catalytic cracking of fish oil industrial residue was investigated to study the effect of temperature, type of catalyst and the heating rate on the yield of organic liquid fraction (OLF) and its acid value. The highest bio-oil yield of 72% (wt.) was obtained at temperature…

Plastic deformation of structural steels under hot-working conditions

Eli Saúl Puchi-Cabrera, Jean-Dominique Guerin, Damien Barbier, Mirentxu Dubar, Jacky Lesage

The present study has been conducted in order to formulate a rational description of the flow stress of structural steels, when these are deformed in tension under hot-working conditions. The simplified formulation that has been developed only involves the analysis of the positive work-hardening…

Application of a Co-evolutionary Genetic Algorithm to solve the Periodic Railway Timetabling Problem

Luis Diego Arenas Pimentel, Rémy Chevrier, Clarisse Dhaenens, Said Hanafi, Joaquin Rodriguez

In train operations, a timetable is used to establish the departure and arrival times for the trains at the stations or other relevant locations in the rail network or a subset of this network. The elaboration of a timetable responds to the commercial needs of the customers, for both passenger and…

Sociotechnical systems resilience : a dissonance engineering point of view

Jean-René Ruault, Frédéric Vanderhaegen, Christophe Kolski

Resilience deals with the capacity to adjust itself face disturbing events, to cope with unforeseeable conditions. Resilience is based upon the dynamic process of "visual piloting". The gap between the specified task and the done activity generates dissonance between beliefs and…

A three-dimensional study of electronic component cooling using a flat heat pipe

Hamdy Hassan, Souad Harmand

In this article, a three-dimensional thermal and hydrodynamic numerical model using a flat heat pipe (vapor chamber) is proposed for cooling of electronic components. The heat pipe is composed of a vapor region sandwiched between two wick regions, which are covered by two flat copper plates. A…

A comprehensive blank development method for forming sheet metal parts

Jianjun Wu, Xin Wu, Liangcai Deng, Hakim Naceur

For some shortcomings in the use of standard radial length development in the blank development for forming sheet metal parts, an improved radial length normal spreading approach considering outside normal direction is developed to resolve blank development in sheet metal forming. Moreover, a…

Alternative Action Plan Generator (A2PG) for elaboration an anticipated feedback

Wided Ben Yahia, Nicolas Tricot, Philippe Polet, Frédéric Vanderhaegen

This paper proposes an original Alternative Action Plan Generator – A2PG, which predicts possible alternatives of the human action plans in which the human operators do not respect the safety rules. These alternatives build an anticipated feedback. Five parameters characterize A2PG. The creation of…

Energetic optimization of the performances of a hot air engine for micro-CHP systems working with a Joule or an Ericsson cycle

Marie Creyx, Eric Delacourt, Céline Morin, Bernard Desmet, Philippe Peultier

The micro combined heat and electrical power systems (micro-CHP) with hot air engines are well adapted for solid biomass upgrading, in particular, the Ericsson engines working with an open cycle and an external combustion. This paper presents a model of an Ericsson engine with a compression and an…

Assessment of ship maneuverability by using a coupling between a nonlinear transient ship maneuvering model and mathematical programming techniques

T. Tran Khanh, Abdellatif Ouahsine, Hakim Naceur, Karima El Wassifi

In this paper, a numerical method based on a coupling between a mathematical model of nonlinear transient ship manoeuvring motion in the horizontal plane and Mathematical Programming (MP) techniques is proposed. The aim of the proposed procedure is an efficient estimation of optimal ship…
