The ternary commutator obstruction for internal crossed modules

T. Vanderlinden, Manfred Hartl

In finitely cocomplete homological categories, co-smash products give rise to (possibly higher-order) commutators of subobjects. We use binary and ternary co-smash products and the associated commutators to give characterisations of internal crossed modules and internal categories, respectively....

Sustainability evaluation framework for ambient intelligences mobile services

Souad Rabah, Nesrine Zoghlami, Mourad Abed

One of the most difficult question to treat, is how to evaluate, build and maintain a sustainable Ambient intelligence (AmI) service? how it can enable society to enjoy a sufficiently high level of life without destroying its natural and environmental support? To conduct this research, the...

Inducing Swirling Flow in Heat Exchanger Pipes for Reduced Fouling Rate

Halldor Pálsson, François Beaubert, Sylvain Lalot

Fouling buildup in circular heat exchanger pipes is a common problem in the industry. Various methods have been proposed to increase the shear stress of the fluid near the pipe wall. This is known to reduce fouling rate, as well as increasing the heat transfer rate of heat exchangers. In this...

Understanding soft evidence as probabilistic evidence : illustration with several use cases

Ali Ben Mrad, Véronique Delcroix, Sylvain Piechowiak, Mohamed-Amine Maalej, Mohamed Abid

This paper aims to get a better understanding of the notions of evidence, probabilistic evidence and likelihood evidence in Bayesian Networks. Evidence comes from an observation of one or several variables. Soft evidence is probabilistic evidence, since the observation consists in a local...

Fast Unsupervised Segmentation Using Active Contours and Belief Functions

Foued Derraz, Laurent Peyrodie, Abdelmalik Taleb-Ahmed, Miloud Boussahla, Gérard Forzy

In this paper, we study Active Contours AC based globally segmentation for vector valued images using evidential Kullback-Leibler KL distance. We investigate the evidential framework to fuse multiple features issued from vector-valued images. This formulation has two main advantages: 1 by the...

Exponential stability of the wave equation on a star shaped network with indefinite sign damping

Farah Abdallah, Denis Mercier, Serge Nicaise

In this paper, we study the stability of the wave equation on a star shaped network in the presence of indefinite sign damping terms. Extending the results of Freitas and Zuazua in [13], we search for sufficient conditions on the damping coefficients for which the problem becomes exponentially...

Optimal stopping and stochastic control differential games for jump diffusions

Fouzia Baghery, Sven Haadem, Bernt Oksendal, Isabelle Turpin

We study stochastic differential games of jump diffusions driven by Brownian motions and compensated Poisson random measures, where one of the players can choose the stochastic control and the other player can decide when to stop the system. We prove a verification theorem for such games in terms...

Natural convection heat transfer of nanofluids along a vertical plate embedded in porous medium

Ziya Uddin, Souad Harmand

The unsteady natural convection heat transfer of nanofluid along a vertical plate embedded in porous medium is investigated. The Darcy-Forchheimer model is used to formulate the problem. Thermal conductivity and viscosity models based on a wide range of experimental data of nanofluids and...
