Composite helical micro pile’s bearing capacity

IOP Conference Series: Materials Science and Engineering, 2020
Abstract It is proposed to use two options of piles’ bearing capacity calculation based on existing Russian codes. Calculation of pipe’s section for an axial load is proposed either. Results of these calculations are compared to the site tests made earlier.

On the Saturation of Astrophysical Dynamos: Numerical Experiments with the No-cosines flow [PDF]

, 2004
In the context of astrophysical dynamos we illustrate that the no-cosines flow, with zero mean helicity, can drive fast dynamo action and study the dynamo's mode of operation during both the linear and non-linear saturation regime: It turns out that in ...

Laboratory simulations of astrophysical jets and solar coronal loops: new results [PDF]

, 2010
An experimental program underway at Caltech has produced plasmas where the shape is neither fixed by the vacuum chamber nor fixed by an external coil set, but instead is determined by self-organization.
