Frequency Separation in Architected Structures using Inverse Methods [PDF]
Journal of Applied and Computational Mechanics, 2021 A major goal in the design of architected structures for low frequency vibration applications (also called mechanical metamaterials, metastructures, elastic metamaterials, auxetic structures) is the creation of regions in the frequency domain where ...

Intermediate‐Mass Stars: Updated Models [PDF]
The Astrophysical Journal, 1999 A new set of stellar models in the mass range 1.2 to 9 $M_{\odot}$ is presented. The adopted chemical compositions cover the typical galactic values, namely $0.0001 \le Z \le 0.02$ and $0.23 \le Y \le 0.28$. A comparison among the most recent compilations of similar stellar models is also discussed.

Anomalous scaling in the Zhang model [PDF]
, 2000 We apply the moment analysis technique to analyze large scale simulations of the Zhang sandpile model. We find that this model shows different scaling behavior depending on the update mechanism used.

Shape descriptors for mode-shape recognition and model updating [PDF]
, 2009 The most widely used method for comparing mode shapes from finite elements and experimental measurements is the Modal Assurance Criterion (MAC), which returns a single numerical value and carries no explicit information on shape features. New techniques,

Experimental Trauma Models: An Update [PDF]
BioMed Research International, 2011 Treatment of polytrauma patients remains a medical as well as socioeconomic challenge. Although diagnostics and therapy improved during the last decades, multiple injuries are still the major cause of fatalities in patients below 45 years of age. Organ dysfunction and organ failure are major complications in patients with major injuries and contribute ...
