R esum e : L'ACC est un r eseau de neurones auto-organis e qui donne une carte de la sous-vari et e d'un nuage de donn ees en grandes dimensions non lin eairement d ependantes. Le principe est de construire une relation entre un espace d'entr ee (les don-n ees) et un espace de sortie (la carte) au moyen d'un ensemble de neurones ayant chacun deux vecteurs-poids : un pour l'entr ee et l'autre po...

Cohesive-frictional soils are widely used in the construction of embankment structures and due to the method of construction, i.e. applying compactive efforts in the vertical direction in these cases, the occurrence of anisotropy in the soil strength and permeability seems to be inevitable. In this study, attempts have been made to evaluate the shear strength of c-f soils through modifying a l...

INTRODUCTION Ultrasound measurements of rectus femoris cross-sectional area (RFCSA) are clinically useful measurements in chronic obstructive pulmonary disease (COPD) and critically ill patients. Technical considerations as to the type of probe used, which affects image resolution, have limited widespread clinical application. We hypothesised that measurement of RFCSA would be similar with line...

The detection of curvilinear structures is an important step for various computer vision applications, ranging from medical image analysis for segmentation of blood vessels, to remote sensing for the identification of roads and rivers, and to biometrics and robotics, among others. This is a nontrivial task especially for the detection of thin or incomplete curvilinear structures surrounded with...

Understanding the mechanism of particle aggregation and dispersion at a liquid surface is important for design fabrication novel materials. The behaviors particles with various compositions interface high-temperature melts, including rapid growth particles, linear or curvilinear motion, wetting separation processes, were observed in situ by confocal laser scanning microscopy (HT-CLSM). We exper...
