Unbiased estimators of specific connectivity
Jean-Paul Jernot, Patricia Jouannot, Christian Lantuéjoul
Izvirni znanstveni članek
Oznake:
This paper deals with the estimation of the specific connectivity of a stationary random set in IRd. It turns out that the ĆnaturalĆ estimator is only asymptotically unbiased. The example of a boolean model of hypercubes illustrates the amplitude of the bias produced when the measurement field is re ...

Practical determination of the coordination number in granular media
Patricia Jouannot-Chesney, Jean-Paul Jernot, Christian Lantuéjoul
Izvirni znanstveni članek
Oznake:
In a random stacking of particles, the coordination number is defined as the mean number of particles touching a given one. A classical measurement by image analysis is directly based on this definition. It can be applied in the theoretical case of a global analysis but some problems occur for pract ...

Evaluating the Euler-Poincaré characteristic of a set using a spatial tessellation
Jean-Paul Jernot, Patricia Jouannot-Chesney, Christian Lantuéjoul
Izvirni znanstveni članek
Oznake:
A new formula is established to evaluate the Euler-Poincare characteristic of a polyconvex subset X in Rd starting only from measurements of X in the cells of a tessellation. Simplifications occur when X is a union of cells of the tessellation, leading to another formula that unifies and extends sev ...

Serial sections through a continuous fiber-reinforced polymer composite
Laurent Bizet, Joël Bréard, Guy Bouquet, Jean-Paul Jernot, Moussa Gomina
Izvirni znanstveni članek
Oznake:
The microstructure of a unidirectional glass-fiber composite material is described seeking especially for the influence of the stitching perpendicular to the reinforcement. Serial cuts are performed through the composite and the microstructure is quantified using global parameters and linear morphol ...

Topological localisation of defects at atomic scale
Christian Lantuéjoul, Gérard Nouet, Pierre Ruterana, Jean-Paul Jernot, Patricia Jouannot-Chesney
Izvirni znanstveni članek
Oznake:
The problem addressed in this paper is the detection of defects on atomic structures. The procedure proposed is in two steps. At first a tessellation isbuilt starting from the atoms. It consists of a partition of the space into cells, and is used to define the neighbourhood relationships between the ...
