Detection, tracking and event localization of jet stream features in 4-D atmospheric data
Detection tracking event localization jet stream features 4D atmospheric data
2014/12/11
We introduce a novel algorithm for the efficient detection and tracking of features in spatiotemporal atmospheric data, as well as for the precise localization of the occurring genesis, lysis, merging...
Detection of millimetric deformation using a terrestrial laser scanner:experiment and application to a rockfall event
millimetric deformation terrestrial laser scanner rockfall event
2009/12/16
Terrestrial laser scanning (TLS) is one of the most promising surveying techniques for rockslope characterization and monitoring. Landslide and rockfall movements can be detected by means of compariso...
Towards operational near real-time flood detection using a split-based automatic thresholding procedure on high resolution TerraSAR-X data
real-time flood detection split-based automatic thresholding procedure TerraSAR-X data
2009/12/16
In this paper, an automatic near-real time (NRT) flood detection approach is presented, which combines histogram thresholding and segmentation based classification, specifically oriented to the analys...
GPS detection of ionospheric perturbation before the 13 February 2001,El Salvador earthquake
GPS detection ionospheric perturbation El Salvador earthquake
2009/12/11
A large earthquake of M6.6 occurred on 13 February 2001 at 14:22:05 UT in El Salvador. We detected ionospheric perturbation before this earthquake using GPS data received from CORS network. Systematic...
Neutron flux variations near the Earth’s crust. A possible tectonic activity detection
Neutron flux variations the Earth’s crust A possible tectonic activity detection
2009/12/10
The present work contains some results of observations of neutron flux variations near the Earth’s surface. The Earth’s crust is determined to be a significant source of thermal and slow neutrons, ori...
Application of a wavelet technique for the detection of earthquake signatures in the geomagnetic field
a wavelet technique earthquake signatures the geomagnetic field
2009/12/9
We developed an algorithm especially adapted to single-station wavelet detection of geomagnetic events, which precede or accompany the earthquakes. The detection problem in this situation is complicat...
