Experimental and Numerical Estimation of the Aerodynamic Forces Induced by the Wind Acting on a Fast-Erecting Crane

Applied Sciences, 2023
The current work concerns the problem of estimating the aerodynamic forces and moments induced by the wind on the fast-erecting 63K crane by Liebherr. In the first step, scaled sectional models of the tower truss and horizontal jib truss are prepared for

Regenerative composition structures

The Annals of Probability, 2005
A new class of random composition structures (the ordered analog of Kingman's partition structures) is defined by a regenerative description of component sizes. Each regenerative composition structure is represented by a process of random sampling of points from an exponential distribution on the positive halfline, and separating the points into ...

Composite structures

, 2020
Conceptual diagram illustrating a large, complex protein with several roles (p-p interaction, ligand binding cavity), along with fragments characterized by linear distribution of hydrophobicity. In such a protein the active site may be constructed from multiple structural units, each of which – when considered on its own – follows the micellar pattern.
