Abstract: Power system state estimation (PSSE) is fundamental for the secure operation of power grids, relying on measurements to estimate real-time conditions. However, conventional weighted least ...

Mechanical engineers have designed a more effective and energy-efficient technology for cooling computer chips. Published in Cell Reports Physical Science, the researchers used a mathematical ...

This paper presents a novel simulation framework for estimating the dynamic response of a full-scale ground-mounted solar panel array under stationary wind loads that are spatially correlated across ...

Abstract The evaluation of the deflection in beams is an indispensable step of the structural design. Currently, many standard codes adopt the Branson’s model. However, the Branson’s model ...

Carson, Wash. May 24, 2022 12 p.m. Updated: May 24, 2022 1 p.m. The U.S. government promised Native tribes in the Pacific Northwest that they could keep fishing as they’d always done. But instead of ...

Continuous beams and one-ways slabs are statically indeterminate structures which i.e they cannot be analyzed using three equations of equilibrium developed to solve unknown moments and reactions of ...

Vibration serviceability of footbridges is important in terms of fitness for purpose. Human-induced dynamic loading is the primary excitation of footbridges and has been researched with traditional ...

Edge fracture is a common problem when forming sheets of advanced high-strength steel (AHSS). Several methods are available to test for edge stretchability in these materials. One of the most popular ...

Plink goes the pendulum arm as it smashes into a 3-inch section of steel. The sound is high-pitched, which tells any metallurgist with a good ear that the piece is brittle. The arm is the business end ...
