Engel probability in wreath products of -groups
Iker de las Heras, Tommaso Toti, Matteo Vannacci
The paper establishes upper and lower bounds for the number of solutions to Engel word equations in certain wreath product groups, proving a stronger form of the Amit‑Ashurst conje…
The lower -series of analytic pro- groups and Hausdorff dimension
Iker de las Heras, Benjamin Klopsch, Anitha Thillaisundaram
Let be a -adic analytic pro- group of dimension . We produce an approximate series which descends regularly in strata and whose terms deviate from the lower -series…
On the Hausdorff spectra of free pro- groups and certain -adic analytic groups
Iker de las Heras, Benjamin Klopsch, Anitha Thillaisundaram
We establish that finitely generated non-abelian direct products of free pro- groups have full Hausdorff spectrum with respect to the lower -series . This co…
Wire twisting stiffness modelling with application in wire race ball bearings. Derivation of analytical formula and Finite Element validation
Josu Aguirrebeitia, Inigo Martin, Iker Heras +2
Since Erich Franke produced the first wire race bearings in 1934, they have not been used profusely until these last years in applications such as computerized tomography, X-ray ma…
Static structural behaviour of wire bearings: comparison with conventional bearings and study of design and operational parameters
Inigo Martin, Iker Heras, Josu Aguirrebeitia +2
In wire bearings the rolling process occurs on raceways machined on steel wires, and the rings are made of light materials such as aluminium. This particular architecture provides…
Structural modeling of crossed roller wire race bearings: analytical submodel for the roller-wire-ring set
Inigo Martin, Iker Heras, Ibai Coria +2
Since wire bearings were patented in 1936, they have been used in applications where weight saving is a key aspect. Nevertheless, little work can be found in literature regarding t…
