Microstructural analysis of skeletal muscle force generation during aging. [PDF]
, 2020 Human aging results in a progressive decline in the active force generation capability of skeletal muscle. While many factors related to the changes of morphological and structural properties in muscle fibers and the extracellular matrix (ECM) have been ...

Meshfree particle method [PDF]
Proceedings Ninth IEEE International Conference on Computer Vision, 2003 Many of the computer vision algorithms have been posed in various forms of differential equations, derived from minimization of specific energy functionals, and the finite element representation and computation have become the de facto numerical strategies for solving these problems. However, for cases where domain mappings between numerical iterations

Geometrically-exact time-integration mesh-free schemes for advection-diffusion problems derived from optimal transportation theory and their connection with particle methods [PDF]
, 2017 We develop an Optimal Transportation Meshfree (OTM) particle method for advection-diffusion in which the concentration or density of the diffusive species is approximated by Dirac measures.

On the infinite particle limit in Lagrangian dynamics and convergence of optimal transportation meshfree methods [PDF]
, 2013 We consider Lagrangian systems in the limit of infinitely many particles. It is shown that the corresponding discrete action functionals Gamma-converge to a continuum action functional acting on probability measures of particle trajectories.

An improved meshless method for finite deformation problem in compressible hyperelastic media
Vietnam Journal of Mechanics, 2021 Hyperelastic materials are considered as special category of elastic solid materials because of their nonlinear complicated constitutive laws. Due to large strain state, the behaviour of such materials is often considered in finite deformation analysis.

Vibration and Buckling Analysis of Skew Sandwich Plate using Radial Basis Collocation Method [PDF]
Mechanics of Advanced Composite Structures, 2023 This paper presents the free vibration and buckling responses of a skew sandwich plate using higher-order shear deformation theory (HSDT). The governing differential equations (GDEs) for the skew sandwich plate are obtained using Hamilton's principle ...
