Applied Element Modelling of Out‐Of‐Plane Instability in Boundary Elements of Thin RC Walls

Earthquake Engineering &Structural Dynamics, Volume 55, Issue 11, Page 2800-2817, September 2026.
ABSTRACT Recent earthquakes in Chile (2010) and New Zealand (2011) caused extensive damage to buildings featuring reinforced concrete (RC) structural walls, with observed failure modes including out‐of‐plane instability of slender walls. This buckling‐type response under combined in‐plane and out‐of‐plane loading has also been documented in ...

Portable Radar for Noncontact Heart Rate Monitoring and Estrus Detection in Dairy Cows

IEEJ Transactions on Electrical and Electronic Engineering, Volume 21, Issue 9, Page 1390-1403, September 2026.
This study introduces a portable radar system for real‐time monitoring of respiratory and heart rates in dairy cows. It uses millimeter‐wave Frequency Modulated Continuous Wave (FMCW) radar to perform noncontact physiological sensing, reducing behavioral disturbance. The radar system's design prioritizes portability, cost‐effectiveness, and robustness,

Preemptive Entry and Technology Diffusion: The Market for Drive‐In Theaters

The RAND Journal of Economics, Volume 57, Issue 3, Page 471-494, Autumn (Fall) 2026.
ABSTRACT This article studies entry preemption in new industries. We first test a key prediction of dynamic entry games: Entry preemption is most relevant in intermediate‐sized markets, where firms face highest uncertainty about future entry. Using US drive‐in theater market (1945–1957) data, we find robust evidence for this non‐monotonic relationship ...

Cable Force Optimization Analysis of Cable‐Stayed Bridges Based on the Plant Growth Simulation Algorithm

Engineering Reports, Volume 8, Issue 8, August 2026.
A plant growth simulation algorithm (PGSA)‐based method optimizes cable forces in cable‐stayed bridges via parameter‐free global search and variable‐step parallel mechanism, achieving uniform force distribution, controlling bending moments and displacements, and enhancing structural performance while overcoming traditional algorithm limitations ...

Low Cycle Repetitive Loading of Ti‐6Al‐4V‐Epoxy Composite Lattice Structures for Enhanced Energy Dissipation and Damage Tolerance

Advanced Engineering Materials, Volume 28, Issue 14, 22 July 2026.
Composite Ti–6Al–4V–epoxy lattice structures are additively manufactured and epoxy infiltrated for cyclic loading. At low lattice volume fractions, hybridization produces synergistic gains in stiffness and energy dissipation. At higher volume fractions, synergy diminishes, although composites still exceed metallic lattices in specific energy ...

Structural optimization of 2-dimensional steel truss beams with different truss members using finite element analysis

Journal of Mechanical Engineering and Sciences
Trusses have long been integral to structural design due to their efficiency in bearing loads. However, a lack of clear guidelines for optimizing truss beams often forces engineers to compromise between performance and cost.
