Metamaterials as artificially structural materials exhibit customized properties unattainable in nature. While dynamic response is highly desired, metamaterials are usually passive and cannot be tuned post-fabrication. A conventional active metamaterial consists of rigid resonators mounted on flexible substrates that permit a limited amount mechanical tuning. Given permanently deform or debond ...

This paper investigates the collapse risk of seismically isolated buildings that are designed by procedures ASCE/SEI 7-16 standard for sites within 5 km active fault controls hazard. The study is based on six-story perimeter frame with special concentrically braced frames a location in California. seismic isolation systems considered this comprised either: (i) triple friction pendulum bearings ...

Abstract The manufacturing process and mechanical instability of high performance magnetocaloric materials hamper the implementation novel geometries for active magnetic regenerators. In this work, La(Fe,Si,Mn)13Hy is shaped into a regenerator with triangular microchannels hydraulic diameter 200–300 μm using that results in highly stable structure. characterized regards to heat transfer, resist...

Context. Far-side helioseismology is a technique used to infer the presence of active regions in far hemisphere Sun based on interpretation oscillations measured near hemisphere. A neural network has been recently developed improve sensitivity seismic maps far-side regions. Aims. Our aim evaluate performance new approach and thoroughly compare it with standard method commonly applied predict fr...
