Optimization of the Initial Post‐Buckling Response of Trusses and Frames by an Asymptotic Approach

International Journal for Numerical Methods in Engineering, Volume 126, Issue 14, 30 July 2025.
ABSTRACT Asymptotic post‐buckling theory is applied to sizing and topology optimization of trusses and frames, exploring its potential and current computational difficulties. We show that the designs' post‐buckling response can be controlled by including the lowest two asymptotic coefficients, representing the initial post‐buckling slope and curvature,

Exploration of Half‐Cycle Length of Converging Circular Wavy Duct with Diverging‐Outlet: Turbulent Water Dynamics

Advanced Theory and Simulations, Volume 8, Issue 7, July 2025.
Increasing half‐cycles intensifies turbulence due to enhanced vortex interactions and flow separation at the diverged‐outlets. Longer wavy ducts are shown to increase flow acceleration, resulting in greater output velocities and more turbulent‐kinetic‐energy production. Wave‐period plays a crucial role in determining turbulent intensity, with amplitude

Synthesis of heat‐integrated thermally coupled nonsharp distillation using self‐adaptive spherical search

AIChE Journal, Volume 71, Issue 7, July 2025.
Abstract Although thermally coupled distillation (TCD) exhibits strong energy efficiency, the possibility of utility cost savings remains debatable. TCD designs that do not consider vapor transport can underestimate costs, making section rearrangement crucial to find more operable configurations.

In Situ Thrust Measurement of Fish During Locomotion; Test Case: Sharks

Ecology and Evolution, Volume 15, Issue 7, July 2025.
We present a novel method that uses in situ video data of fish locomotion to calculate thrust. This methodology was applied to several large elasmobranch species, which are typically challenging to measure. Our findings indicate that coastal pelagic species exhibited lower scaled thrust than benthic species, suggesting that benthic species may be less ...
