Development of Nationwide Road Quality Map: Remote Sensing Meets Field Sensing

open access: yesSensors, 2021
In this study, we measured the in situ international roughness index (IRI) for first-degree roads spanning more than 1300 km in East Azerbaijan Province, Iran, using a quarter car (QC). Since road quality mapping with in situ measurements is a costly and

Visual Field Maps in Human Cortex [PDF]

open access: yesNeuron, 2007
Much of the visual cortex is organized into visual field maps: nearby neurons have receptive fields at nearby locations in the image. Mammalian species generally have multiple visual field maps with each species having similar, but not identical, maps.

Field Map Reconstruction in Magnetic Resonance Imaging Using Bayesian Estimation

open access: yesSensors, 2009
Field inhomogeneities in Magnetic Resonance Imaging (MRI) can cause blur or image distortion as they produce off-resonance frequency at each voxel. These effects can be corrected if an accurate field map is available. Field maps can be estimated starting

A steerable UV laser system for the calibration of liquid argon time projection chambers [PDF]

open access: yes, 2014
A number of liquid argon time projection chambers (LAr TPC's) are being build or are proposed for neutrino experiments on long- and short baseline beams. For these detectors a distortion in the drift field due to geometrical or physics reasons can affect
