Performance of the PR connections under combined Axial-tension and moment loading
Electronic Journal of Structural Engineering, 2010 The inherent moment capacity of bolted top-seat angle connections with double web angles (TSDW), categorized as partially restrained (PR) connections according to AISC-LRFD specifications, can be considered in analyses of semi-rigid connections ...

Controlling beam trajectory and transport in a tapered helical undulator
Journal of Synchrotron Radiation, Volume 32, Issue 2, Page 331-339, March 2025.In this work the transport of low energy electrons through helical magnetic undulators is discussed with application for THz generation in waveguide free‐electron lasers. To optimize beam transmission, the off‐axis fields sampled by low energy beams are tuned with a 3D pulsed‐wire measurement technique that reveals localized errors in the quadrupole ...

OC6 Phase IV: Validation of CFD Models for Stiesdal TetraSpar Floating Offshore Wind Platform
Wind Energy, Volume 28, Issue 1, January 2025.ABSTRACT With only a few floating offshore wind turbine (FOWT) farms deployed anywhere in the world, FOWT technology is still in its infancy, building on a modicum of real‐world experience to advance the nascent industry. To support further development, engineers rely heavily on modeling tools to accurately portray the behavior of these complex systems
