Background: Highly vascular tissue is a combination of solid and fluid components. The interaction between these two phases during deformation creates a viscoelastic or rate‐dependent behavior. To understand how fluid and solid components contribute to the injury response of liver tissue, a constitutive model is needed which reflects the biphasic nature of the material. This study aims to captu...

Usually, the viscoelastic (VE) response of polymers for applications in composites is obtained uniaxial strainor stress-controlled tests. However, analyzing multimaterial structures by Finite Element Method (FEM) or other numerical analytical tools, a material model terms complete set compliance functions and/or relaxation required. In this paper, methodology and exact expressions calculating w...

Finding the sparse representation of a signal in an overcomplete dictionary has attracted a lot of attention over the past years. Traditional approaches such as Basis Pursuit are based on relaxing a nonconvex `0-minimization problem [1]–[3]. In [4], a new polynomial complexity algorithm, ProSparse, is presented. ProSparse solves the sparse representation problem when the dictionary is the union...

Abstract In frequency analysis an often appearing problem is the reconstruction of a signal from given samples. Since samples are usually noised, pure interpolating approaches not recommended and appropriate approximation methods more suitable as they can be interpreted kind denoising. Two widely used. One uses reflection coefficients finite sequence Szegő polynomials other one zeros so called ...
