Projection, Spatial Correlations, and Anisotropies in a Large and Complete Sample of Abell Clusters [PDF]
, 1999 An analysis of R >= 1 Abell clusters is presented for samples containing recent redshifts from the MX Northern Abell Cluster Survey. The newly obtained redshifts from the MX Survey as well as those from the ESO Nearby Abell Cluster Survey (ENACS) provide

Non-line-of-sight propagation in object localization: a survey
Gong-kuang zidonghua, 2020 Due to the existence of obstacles, none-line-of-sight(NLOS) propagation is common in localization scenes like mines, which causes refraction, reflection, diffraction and scattering of localization signals, leads to the increase of ranging error, and ...

Fast Back-Projection for Non-Line of Sight Reconstruction [PDF]
, 2017 Recent works have demonstrated non-line of sight (NLOS) reconstruction by using the time-resolved signal frommultiply scattered light. These works combine ultrafast imaging systems with computation, which back-projects the recorded space-time signal to ...
