Measurement and modeling of diffuse ultraviolet radiation: A review
Photochemistry and Photobiology, Volume 102, Issue 5, Page 1048-1059, September/October 2026.Solar UV radiation consists of direct and diffuse UV components. The diffuse component contributes to the exposure received by humans and to the risk of skin cancer and sun‐related eye disorders. This review aims to determine future research directions for the measurement and modeling of diffuse solar UV radiation.

Novel sensor location scheme using time-of-arrival estimates
, 2012 This study proposes a novel scheme for locating an asynchronous sensor with synchronised beacons using time-of-arrival (TOA) estimates. In this scheme, a reference beacon initiates the localisation by emitting a ranging signal, and the sensor position is
