Photoacoustics, 2019 In this article we address the numeric inversion of optoacoustic signals to initial stress profiles. Therefore we study a Volterra integral equation of the second kind that describes the shape transformation of propagating stress waves in the paraxial ...

Improvement of Fourier Polarimetry for applications in tomographic photoelasticity [PDF]
, 2006 The use of the Fourier Polarimetry method has been demonstrated to extract the three characteristic parameters in integrated photoelasticity. In contrast to the phase-stepping method, it has been shown that the Fourier method is more accurate.

Motion compensated micro-CT reconstruction for in-situ analysis of dynamic processes [PDF]
, 2018 This work presents a framework to exploit the synergy between Digital Volume Correlation ( DVC) and iterative CT reconstruction to enhance the quality of high-resolution dynamic X-ray CT (4D-mu CT) and obtain quantitative results from the acquired ...

Reconstruction of shear modulus and viscosity of biological tissues from displacement measurement
Measurement: Sensors, 2021 We present a novel reconstruction method for magnetic resonance elastography, in which the shear modulus and viscosity of biological tissues are estimated from the externally oscillated displacement field obtained using magnetic resonance imaging.

The Use of Tractography-Based Targeting in Deep Brain Stimulation for Psychiatric Indications
Frontiers in Human Neuroscience, 2020 Deep Brain Stimulation (DBS) has been investigated as a treatment option for patients with refractory psychiatric illness. Over the past two decades, neuroimaging developments have helped to advance the field, particularly the use of diffusion tensor ...

Image-Based Stress Field Reconstruction in Complex Media [PDF]
In many instances in life, materials are subject to deformation at high rates, for example: impact, crash, metal forming or pulsed welding. In this context, the transient and inhomogeneous nature of such loading as well as the strong multi-physic couplings induced by quasi-adiabatic conditions make: the experimental capture of the mechanical response ...

Time scales in shear banding of wormlike micelles [PDF]
, 2002 Transient stress and birefringence measurements are performed on wormlike micellar solutions that "shear band", i.e. undergo flow-induced coexistence of states of different viscosities along a constant stress "plateau".

CAD-CAE methods to support restoration and museum exhibition of bronze statues: the “Principe Ellenistico” [PDF]
, 2018 Ancient bronze statues mainly require material integrity assessment and restoration. Restoration may include also the update of the museum exhibition, defining new structural frames and fragment re-composition to preserve the statue and improve the ...

Determination of the characteristic directions of lossless linear optical elements
, 2006 We show that the problem of finding the primary and secondary characteristic directions of a linear lossless optical element can be reformulated in terms of an eigenvalue problem related to the unimodular factor of the transfer matrix of the optical ...
