Efficient Multigrid Preconditioners for Atmospheric Flow Simulations at High Aspect Ratio [PDF]
, 2015 Many problems in fluid modelling require the efficient solution of highly anisotropic elliptic partial differential equations (PDEs) in "flat" domains. For example, in numerical weather- and climate-prediction an elliptic PDE for the pressure correction ...

High‐Aspect‐Ratio Nanostructured Surfaces as Biological Metamaterials [PDF]
Advanced Materials, 2020 AbstractMaterials patterned with high‐aspect‐ratio nanostructures have features on similar length scales to cellular components. These surfaces are an extreme topography on the cellular level and have become useful tools for perturbing and sensing the cellular environment. Motivation comes from the ability of high‐aspect‐ratio nanostructures to deliver

Flux-closure domains in high aspect ratio electroless-deposited CoNiB nanotubes
SciPost Physics, 2018 We report the imaging of magnetic domains in ferromagnetic CoNiB nanotubes with very long aspect ratio, fabricated by electroless plating. While axial magnetization is expected for long tubes made of soft magnetic materials, we evidence series of ...

Elastic Model for High Aspect Ratio Airplane Landing Impact Analysis
Hangkong gongcheng jinzhan, 2020 The generalized displacement of installation point, structural damping coefficient and elastic vibration frequency can influence the energy dissipation efficiency of load impact. Taking Global Hawk UAV as an example, the dynamic equation of rigid-elastic

Dynamic range of nanotube- and nanowire-based electromechanical systems [PDF]
, 2005 Nanomechanical resonators with high aspect ratio, such as nanotubes and nanowires are of interest due to their expected high sensitivity. However, a strongly nonlinear response combined with a high thermomechanical noise level limits the useful linear ...

Ultrasharp High-aspect-ratio Tetrahedral Molded Tips [PDF]
Sensors and Materials, 2019 The fabrication of sharp tips manufactured using silicon or using a silicon mold is a widely used method with a wide range of applications. In this study, we extend our work on the fabrication of tetrahedral molds in (111) silicon and the fabrication of tips based on those molds.
