A theoretical model was previously developed to evaluate the relationship between the dynamics of ultrasonic speckle and its underlying tissue. The model is divided into an instrumental part represented by the point spread function (in the far field) of the ultrasonic apparatus and a moving tissue component described by a collection of scatterers. By computing the convolution of these terms and...

Stress relaxation and structural analysis were used to investigate the zonally differentiated microstructural response to compression of the integrated cartilage-on-bone tissue system. Fifteen cartilage-on-bone samples were divided into three equal groups and their stress relaxation responses obtained at three different levels of axial compressive strain defined as low (~20%), medium (~40%) and...

Myopia is characterized by an increase in axial length of the eye, but the reasons for the axial elongation are still unknown. Higher intraocular pressure (IOP) has been associated with myopia and could be involved in eye enlargement. The purpose of this study was to investigate the effect of intraocular pressure on the geometry of the chick eye and to investigate whether an increase in IOP cou...

It has been known that geometric softening can induce strain localizations in solids. However, it is very difficult to analytically capture the localized deformation states within a threedimensional framework, especially when the deformation is large. In this paper, we introduce a novel approach, which resembles the use of a spline to approximate a curve, to construct analytical (asymptotic) so...

The feasibility of real-time non-invasive spatio-temporal temperature estimation from pulse-echo diagnostic ultra-sound data has been previously demonstrated in stationary phantoms. The method is based on rst estimating the axial shifts of the RF-echo data due to local changes in the speed of sound and thermal expansion in the propagating medium, and then diierentiating these estimates along ax...

We study static non-axial octupole deformations in proton-rich Z = N nuclei, Ge, Se, Kr, Sr, Zr and Mo, by using the Skyrme Hartree-Fock plus BCS calculation with no restrictions on the nuclear shape. The calculation predicts that the oblate ground state in Se is extremely soft for the Y33 triangular deformation, and that in Zr the low-lying local minimum state coexisting with the prolate groun...

Parton distributions in impact parameter space, which are obtained by Fourier transforming GPDs, exhibit a significant deviation from axial symmetry when target and/or quark are transversely polarized. In combination with the final state interactions, this transverse deformation provides a natural mechanism for naive-T odd transverse single-spin asymmetries in semi-inclusive DIS. The deformatio...

Curve-pair based deformation is an extension of axial deformation for providing more intuitive and convenient control of object deformation. In this paper, we investigate the problem of direct manipulation of curve-pair based deformation with geometric constraints. With different objective functions, two kinds of constrained optimization problems are derived from the direct manipulation problem...

in this study, to determine poisson’s ratio and modulus of elasticity of white seedless grapes during maturation, the fresh fruit samples were harvested from a vineyard at seven sequential weeks from 6th september to 18th october. in each run, six grape berries were randomly selected and the static loading test and digital photography were done together. considering true shape of the fruit and ...
