RFID Backscatter Based Sport Motion Sensing Using ECOC-Based SVM

open access: yesSensors, 2023
With the advent of the 5G era, radio frequency identification (RFID) has been widely applied in various fields as one of the key technologies for the Internet of Things (IoT) to realize the Internet of Everything (IoE). In recent years, RFID-based motion

Integrability Breaking from Backscattering

open access: yesPhysical Review Letters, 2023
We analyze the onset of diffusive hydrodynamics in the one-dimensional hard-rod gas subject to stochastic backscattering. While this perturbation breaks integrability and leads to a crossover from ballistic to diffusive transport, it preserves infinitely many conserved quantities corresponding to even moments of the velocity distribution of the gas. In

Spatio-temporal influence of tundra snow properties on Ku-band (17.2 GHz) backscatter [PDF]

open access: yes, 2015
During the 2010/11 boreal winter, a distributed set of backscatter measurements was collected using a ground-based Ku-band (17.2 GHz) scatterometer system at 26 open tundra sites.

Calibration of laser scanning intensity data using brightness targets

open access: yesGeodesy and Cartography, 2012
The paper examines a radiometric calibration method used at the Finnish Geodetic Institute (FGI). The brightness calibration targets and calibration scheme of airborne laser scanner intensity data is observed. For calibrating laser scanner intensity data,
