Determining diffusivity and dissipation of diffuse body waves in concrete with multiple planar boundaries
Hao Cheng, Katrin Löer, Max A. N. Hendriks +1
This paper presents a new method for determining the diffusive properties of diffuse body waves, specifically diffusivity and dissipation, in concrete with multiple planar boundari…
Determining the acoustoelastic effect of longitudinal waves propagating inclined to principal stress directions in concrete: theory and experimental validation
Hao Cheng, Katrin Löer, Max A. N. Hendriks +1
The concept of acoustoelasticity pertains to changes in elastic wave velocity within a medium when subjected to initial stresses. However, existing acoustoelastic expressions are p…
Influence of elastic deformations on body-wave velocity in solids: a case study considering shear deformations in concrete
Hao Cheng, Cornelis Weemstra, Katrin Löer +2
This paper investigates the influence of elastic deformation on the velocity of body waves in compressible isotropic materials making use of the framework of acoustoelasticity. Spe…
Progressive Divide-and-Conquer via Subsampling Decomposition for Accelerated MRI
Chong Wang, Lanqing Guo, Yufei Wang +3
Deep unfolding networks (DUN) have emerged as a popular iterative framework for accelerated magnetic resonance imaging (MRI) reconstruction. However, conventional DUN aims to recon…
