Joint Traffic Reshaping and Channel Reconfiguration in RIS-assisted Semantic NOMA Communications

Posted by klaurent UCAS

Kavli Affiliate: Bo Gu | First 5 Authors: Songhan Zhao, Songhan Zhao, , , | Summary: In this paper, we consider a semantic-aware reconfigurable intelligent surface (RIS)-assisted wireless network, where multiple semantic users (SUs) simultaneously transmit semantic information to an access point (AP) by using the non-orthogonal multiple access (NOMA) method. The SUs can reshape […]

Visual Surface Wave Elastography: Revealing Subsurface Physical Properties via Visible Surface Waves

Posted by klaurent Caltech

Kavli Affiliate: Chiara Daraio | First 5 Authors: Alexander C. Ogren, Alexander C. Ogren, , , | Summary: Wave propagation on the surface of a material contains information about physical properties beneath its surface. We propose a method for inferring the thickness and stiffness of a structure from just a video of waves on its […]
