WHEN ROMAN ANTIQUITY AND RENAISSANCE CAME TOGETHER IN VIRTUAL 3D ENVIRONMENT: 3D MODELLING CONSIDERATIONS [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2020
This paper is a review of the modelling of two edifices located in a city which developed on the vestiges of a Roman city during antiquity endowed in the 4th century with a military camp. The term castellum is used for the first structure.

Radiometric and safety assessment of a 'low-level red-light' myopia control device. [PDF]

open access: yesOphthalmic Physiol Opt
Abstract Purpose Recent literature has demonstrated that ‘low‐level red‐light therapy’ may be effective at slowing axial elongation in children, but reports have questioned the safety of some red‐light devices. The current work explored the beam characteristics and hazard potential for a myopia control red‐light device.

Assimilation of vegetation optical depth retrievals from passive microwave radiometry

open access: yesHydrology and Earth System Sciences, 2020
. Vegetation optical depth (VOD) retrievals from passive microwave sensors provide analog estimates of above-ground canopy biomass. This study presents the development and analysis of assimilating VOD retrievals from X-, C-, and L-band passive microwave ...

Multiyear in-situ L-band microwave radiometry of land surface processes on the Tibetan Plateau

open access: yesScientific Data, 2020
We report a unique multiyear L-band microwave radiometry dataset collected at the Maqu site on the eastern Tibetan Plateau and demonstrate its utilities in advancing our understandings of microwave observations of land surface processes.

Real-Time Passive Brain Monitoring System Using Near-Field Microwave Radiometry

open access: yesIEEE Transactions on Biomedical Engineering, 2020
Objective: Near-field microwave radiometry has emerged as a tool for real-time passive monitoring of local brain activation, possibly attributed to local changes in blood flow that correspond to temperature and/or conductivity changes.
