TL;DR: An insight is gained into the sensitivity of each physical parameter used in Biot's theory modified by the model of Johnson et al. (1987) for viscous exchange between fluid and structure.

TL;DR: In this article, a coulombian approach is used to derive the magnetic field created by permanent magnetized rings for axially magnetized magnets, and the results determined by a 2D analytical approximation to those for the 3D analytical formulation, in order to determine the range of validity of the 2D approximation.

TL;DR: An ultrasonic reflectivity method is proposed for measuring porosity and tortuosity of porous materials having a rigid frame based on measurement of reflected wave by the first interface of a slab of rigid porous material.

TL;DR: It is shown that the connection between the fractional calculus and the behavior of materials with memory allows time-domain wave equations, the coefficients of which are no longer frequency dependent, to be worked out, and lead to the complete determination of the porous medium parameters.

TL;DR: Experimental results are compared with theoretical predictions for slow and fast waves transmitted through human cancellous bone samples.
