, 2010 In this research note, we provide a variational basis for the optimal artificial diffusion method, which has been a cornerstone in developing many stabilized methods. The optimal artificial diffusion method produces exact nodal solutions when applied to

Zebrafish inversin mutants develop scoliosis in the absence of laterality defects
Developmental Dynamics, EarlyView.Abstract Background Human mutations in INVERSIN are associated with nephronophthisis, variable penetrance of situs inversus and congenital heart disease. Inversin has been shown to localize to cilia and many of the patient phenotypes are attributed to disrupted cilia function.

A Variational r-Adaption and Shape-Optimization Method for Finite-Deformation Elasticity [PDF]
, 2003 This paper is concerned with the formulation of a variational r-adaption method for finite-deformation elastostatic problems. The distinguishing characteristic of the method is that the variational principle simultaneously supplies the solution, the ...

Earthquake Engineering and Resilience, EarlyView.“It was found that good ductility can be achieved in CFRP‐strengthened frames, and this result was validated through experimental testing.” ABSTRACT Reinforced concrete structures are increasingly vulnerable to deterioration by steel reinforcement corrosion, resulting in severe loss of fracture strength and service life, particularly in severe ...

Earthquake Engineering &Structural Dynamics, EarlyView.ABSTRACT Multi‐supported non‐structural components (NSCs) are prone to seismic damage, yet their response prediction remains challenging when support motions are spatially incoherent. This study proposes an enhanced quasi‐static condensation (EQSC) method for linear, lightweight, dynamically detuned multi‐supported NSCs under the neglect of primary ...

Localized nodal solutions for parameter-dependent quasilinear Schrödinger equations
, 2021 In this article, we apply a new variational perturbation method to study the existence of localized nodal solutions for parameter-dependent semiclassical quasilinear Schrödinger equations, under a certain parametric conditions ...

Applied Element Modelling of Out‐Of‐Plane Instability in Boundary Elements of Thin RC Walls
Earthquake Engineering &Structural Dynamics, EarlyView.ABSTRACT Recent earthquakes in Chile (2010) and New Zealand (2011) caused extensive damage to buildings featuring reinforced concrete (RC) structural walls, with observed failure modes including out‐of‐plane instability of slender walls. This buckling‐type response under combined in‐plane and out‐of‐plane loading has also been documented in ...

CONFIGURATIONAL FORCES IN STRUCTURAL AND CONTINUUM OPTIMISATION [PDF]
, 2008 This thesis deals with optimisation using the principles of continuum mechanics. Both shape and mesh optimisation will be covered. A unified approach will be introduced to obtain shape and mesh optimisation for hyperelastic, hyperelastodynamic and ...
