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.

Settlement based load capacity curve for single helix helical pile in c - ϕ soil

Soils and Foundations, 2023
Helical piles are getting increasingly popular for lightweight engineering applications. Currently, the helical pile is mostly designed with torque capacity; however, it cannot explain the foundation's anticipated settlement.

Last orbits of binary black holes

, 2002
Binary black hole systems in the pre-coalescence stage are numerically constructed by demanding that the associated spacetime admits a helical Killing vector. Comparison with third order post-Newtonian calculations indicates a rather good agreement until

Effect of geometric characteristics of helical piles on the lateral displacement in sandy slopes by loading surcharge

Results in Engineering
Helical piles are a group of deep foundations with a good bearing capacity against axial and lateral forces. Despite extensive research on the performance on flat ground, fewer studies have been conducted on the performance of helical piles on slopes ...
