Abstract: We propose seismic elastic full-waveform inversion (EFWI) using both the multiparametric approximate Hessian and the discrete cosine transform (DCT). EFWI is a promising technology for ...

Abstract: In this paper, we focus on the validity of using a Variable Structured Elastic Actuator (VSEA) for a hopping robot. A VSEA is proposed by Miura and Katsura. The VSEA is composed of an ...

The clinical performance of dental implants is strongly defined by biomechanical principles. The aim of this study was to quantify the Vicker's hardness (VHN) and elastic modulus (E) surround bone to ...

A new shape shifting material can twist, bend, and snap into more than a dozen 3D forms without motors or wires, a breakthrough in "snapping morphogenesis" by NC State researchers led by Jie Yin. GOP ...
