This article presents a micromechanics-based model that constitutively relates internal network physics of hydrogel-based nanocomposites with their visco-super-elastic mechanics. The is based on the Eshelby inclusion theory combined to concept cubic material volume take into account effective role inorganic nanoparticles finite-strain response hydrogels. Dynamic bonds between hydrogel chains an...

This chapter reviews various elastic matching techniques for handwritten character recognition. Elastic matching is formulated as an optimization problem of planar matching, or pixel-to-pixel correspondence, between two character images under a certain matching model, such as affine and nonlinear. Use of elastic matching instead of rigid matching improves the robustness of recognition systems a...

Elastic property-porosity relationships are derived directly from microtomographic images. This is illustrated for a suite of four samples of Fontainebleau sandstone with porosities ranging from 7.5% to 22%. A finiteelement method is used to derive the elastic properties of digitized images. By estimating and minimizing several sources of numerical error, very accurate predictions of properties...

We prove a general version of the super-replication theorem, which applies to Kabanov’s model of foreign exchange markets under proportional transaction costs. The market is described by a matrix-valued càdlàg bid-ask process (Πt)t∈[0,T ] evolving in continuous time. We propose a new definition of admissible portfolio processes as predictable (not necessarily right or left continuous) processes...

To characterize the mechanical properties of the contracting left ventricle, we studied the changes in left ventricular systolic pressure following step-like perturbations (+/- 3 ml) in ventricular volume, using an isovolumically beating, isolated canine heart preparation. Three mechanical properties (elasticity, resistance, and a deactivation effect) were identified. The elastic property diffe...
