Effect of particle size distribution on the correlation between liquefaction resistance and shear wave velocity of granular soils

EPJ Web of Conferences, 2017
Shear wave method has been increasingly popular in assessing the liquefaction potential of granular soils. Two particle-scale parameters, the inter-particle friction and the shear modulus of grains, play vital roles in correlation between Cyclic ...

Monitoring of Indoor Air Quality in a Classroom Combining a Low-Cost Sensor System and Machine Learning

Chemosensors
Monitoring indoor air quality in schools is essential, particularly as children are highly vulnerable to air pollution. This study evaluates the performance of the low-cost sensor-based air quality monitoring system ENSENSIA, during a 3-week campaign in ...

Assessment and Correction of Calibration Consistency in Medium Resolution Imagers’ Split-Window Channels Using Dome C

IEEE Access
Accurate radiometric calibration consistency is fundamental for quantitative remote sensing retrievals using multi-source sensors. Previous studies have mainly evaluated inter-sensor calibration consistency (e.g., MODIS and VIIRS) but lacked systematic ...

Jet Energy Calibration in the CMS experiment

EPJ Web of Conferences, 2013
Jet reconstruction and calibration in the CMS experiment are complicated by the nonlinear response of the calorimeters and high pileup conditions. These difficulties are mitigated at CMS by utilising the particle flow approach. The jet energy calibration
