Monitoring of Water Leakages from Pipes through Geophysical Imaging Methods

Surface Geophysical Methods for Detection of Underground Mine Workings

Efforts to delineate underground mine workings in the vicinity of tailings impoundments has relied on available maps and confirmatory boreholes. Often the characterization of regions between boreholes remains suspect or entirely unknown. Surface geophysical measurements can be used to supplement the borehole data and better delineate these intermediate zones. Furthermore, geophysics can be used...

Integrated Inversion of Numerical Geophysical Models Using Artificial Neural Networks

A unified modelling procedure is proposed to jointly interpret the variations observed in geophysical data and to properly take into account the relationship between the intrusive processes and the geophysical variations expected at the ground surface. We focus on the joint inversion of geophysical data by a procedure based on Artificial Neural Network (ANN) for the estimation of the volcanic s...

Onboard Detection of Snow, Ice, Clouds and Other Geophysical Processes Using Kernel Methods

The detection of clouds within a satellite image is essential for retrieving surface geophysical parameters from optical and thermal imagery. Even a small percentage of cloud cover within a radiometer pixel can adversely affect the determination of surface variables such as albedo and temperature. Thus, onboard processing of satellite data requires reliable automated cloud detection algorithms ...
