Quantum cryptographic ranging [PDF]
, 2001 We present a system to measure the distance between two parties that allows only trusted people to access the result. The security of the protocol is guaranteed by the complementarity principle in quantum mechanics.

Ranging Behaviour of Commercial Free-Range Laying Hens [PDF]
Animals, 2016 In this study, the range use and behaviour of laying hens in commercial free-range flocks was explored. Six flocks were each visited on four separate days and data collected from their outdoor area (divided into zones based on distance from shed and available resources).

Design of pulse laser high-precision ranging algorithm under low signal-to-noise ratio
Open Physics, 2022 Because the traditional pulse laser high-precision ranging method has the problems of low ranging accuracy and long ranging time, a pulse laser high-precision ranging algorithm under low signal-to-noise ratio is proposed.

Mid-range probing—towards range-guided particle therapy [PDF]
Physics in Medicine & Biology, 2017 Particle therapy can achieve excellent dose localization but is sensitive to range uncertainty. Therefore, online in vivo range verification before treatment is critical for treatment safety and quality assurance. We introduce a novel range-probing technique that uses mid-range treatment spots selected from the treatment plan as probing beams to be ...

A Two-Stage Reconstruction Processor for Human Detection in Compressive Sensing CMOS Radar
Sensors, 2018 Complementary metal-oxide-semiconductor (CMOS) radar has recently gained much research attraction because small and low-power CMOS devices are very suitable for deploying sensing nodes in a low-power wireless sensing system.
