Despite of recent progresses in occupant safety, the protection of children are not still optimal. To offer a better understanding of child injury mechanisms, the present study proposes a humanlike finite element model of a three years old child’s neck. The subject was scanned with a medical scanner. The images were first semiautomatically segmented in order to extract the soft tissues and the ...

As flax fibres exhibit good mechanical properties and low cost, they are more and more considered, since the early 2000’s, as efficient reinforcement for polymer based composites in replacement of E-glass fibres in automotive or building areas. The properties of the elementary fibres are now relatively well-known (strength comprised between 600 and 2000 MPa, Young’s modulus around 50 GPa and fa...

Here, we present a family of time series with a simple growth constraint. This family can be the basis of a model to apply to emerging computation in business and micro-economy where global functions can be expressed from local rules. We explicit a double statistics on these series which allows to establish a one-to-one correspondence between three other ballot-like strunctures.

In this paper, we propose a new method to detect ellipsoidal shapes. This method combine two well known approach : the Modified Hough Transform and the Elliptic Fourier Decomposition. The applications of this method are, for instance, medical imaging (ultrasound imaging, X-rayed, . . .), biological imaging (cell count) or intelligent vision in robotic. We have apply our method to the particular...

In terms of general approach the problem of optimal design and construction is considered. In the present paper an optimization method is elaborated and takes on the process in establishing mathematical models for conducting real procedure that allows an optimal design and construction of asynchronous electrical motor of 13kW. The proposed method is a multi-objective optimization approach that ...

This paper presents an implementation of an iterative method based on the waves concept for analyzing patch antennas fed by coaxial probes. This method includes a two-dimensional fast Fourier transform (FFT-2D) in a wave guide environment. The method has the advantage of simplicity in that it does not involve basis functions and inversion of matrices, as used in other calculation methods. There...

The matter of this thesis is the modelling of Open Distance Learning (ODL)’s platforms basing on their characteristics. We shall use tools of modelling as UML (diagrams, extensions of the meta model, profils,...). Proposed results should take into account the specificities of ODL's platforms (variety actors, educational resources, assistance, degree of freedom, collaboration between learners,.....
