Vertical Seismic Profile Wavefield Separation Using Median Filtering Constrained by the Linear Radon Transform

open access: yesApplied Sciences, 2018
Separation of downgoing and upgoing P-waves and S-waves in an offset 2D/3D vertical seismic profile (VSP) record is a basic step in VSP data processing. Radon transform and median filtering methods are commonly used to separate wavefields.

Rotation Invariant Automatic Infrared Target Recognition using G-Radon

open access: yesMATEC Web of Conferences, 2016
In recent research, automatic target recognition (ATR) of infrared targets has been taking a lot of interest to the researchers. A rotation invariant method is useful in target recognition, classification and image analysis to reduce the number of ...

Trkalian fields and Radon transformation

open access: yes, 2010
We write the spherical curl transformation for Trkalian fields using differential forms. Then we consider Radon transform of these fields. The Radon transform of a Trkalian field satisfies a corresponding eigenvalue equation on a sphere in transform ...

Influences of season, ventilation, SARS-CoV-2 pandemic protective measures, and energy-shortage on VOC levels in Western Switzerland’s primary schools

open access: yesIndoor Environments
Indoor air pollution is a major threat to human health, contributing to both acute and chronic diseases in exposed individuals. School environments are particularly at risk, as they host vulnerable populations which spend a considerable amount of time ...
