Dual-energy X-ray tomography is considered in a context where the target under imaging consists of two distinct materials. The materials are assumed to be possibly intertwined space, but at any given location there only one material present. Further, energies chosen so that clear difference spectral dependence attenuation coefficients A novel regularizer presented for inverse problem reconstruc...

The idea of a material body endowed with both translational and rotational degrees of freedom stems from the seminal work of the Cosserat brothers (Cosserat and Cosserat, 1909). A triad of orthonormal directors (d )i=1,3 is associated to the microstructure of each material point. The material transformation describes the displacement u of the material point and the rotation R∼ with respect to t...

A perennial plant Miscanthus x giganteus has found its habitat and multiple applications in Europe, despite the fact that it originates from Asia. This study presents potential use of this new lightweight concrete materials so-called bio-concretes. The above-ground part was harvested, dried, crushed, mixed with binders different proportions. After casting drying, samples were characterized phys...
