Abstract : In this study, the experimental results are present the evolution of mechanical properties according to some aggressive environments with a coating of

The characterization method for pipe enclosures proposed by CSTB is based on the current EN 14366 standard, where two main performance indicators can be determined for

IV. MODAL COMPUTATION OF THE WHOLE CLARINET In order to simulate the modal behavior of the complete clarinet, we have associated a finite-element model of ⬇ 10 cm of pipe with

The model accounts for the following transport processes: advection and hydrodynamic dispersion in the fractures, matrix diffusion, diffusion into stagnant zones within the fracture

In Figure 5, we present a comparison of the signal to clutter ratio (SCR) for 17 B-scan images for different methods, the mean sub- traction (MS), window mean subtraction

In the current paper, it is demonstrated that this typical evolution of the free surface, originated by shrinkage at solidification front and compensating feeding

Methods We studied content validity, internal consistency, convergent validity (vs physician-estimated satisfaction), and test-retest reliability of the French version of the
