A new approach for residual gravity anomaly profile interpretations: Forced Neural Network (FNN)
Forced Neural Network gravity anomaly modeling synthetic model Gulf of Mexico
2015/9/8
This paper presents a new approach for interpretation of residual gravity anomaly profiles, assuming horizontal
cylinders as source. The new method, called Forced Neural Network (FNN), is introduced ...
Evaluation of automatic ionogram scaling for use in real-time ionospheric density profile specification: Dourbes DGS-256/ARTIST-4 performance
Ionosphere Plasma Physics Wave propagation Instruments and techniques
2015/8/24
Statistical evaluation of the Dourbes (4.6˚E, 50.1˚N) digisonde automatic scaling of the more frequently used ionospheric parameters (foF2, foF1, foE, h’F2, h’F, h’E, and M3000F2) was perfor...
Variations of soil profile characteristics due to varying time spans since ice retreat in the inner Nordfjord, western Norway
soil profile characteristics due varying time spans since ice retreat inner Nordfjord western Norway
2015/1/6
In the Erdalen and Bødalen drainage basins located in the inner Nordfjord in western Norway the soils were formed after deglaciation. The climate in the uppermost valley areas is sub-arctic ocean...
Existence of Equilibrium Points and their Linear Stability in the Generalized Photogravitational Chermnykh-Like Problem with Power-law Profile
Photogravitational:Oblateness:RTBP:Chermnykh-Like problem
2011/8/18
Abstract: We consider the modified restricted three body problem with power-law density profile of disk, which rotates around the center of mass of the system with perturbed mean motion. Using analyti...
A discrete random model describing bedrock profile abrasion
discrete random model bedrock profile abrasion Geophysics
2011/8/4
Abstract: We use a simple, collision-based, discrete, random abrasion model to compute the profiles for the stoss faces in a bedrock abrasion process. The model is the discrete equivalent of the gener...
Non-stationary temporal characterization of the temperature profile of a soil exposed to frost in south-eastern Canada
Non-stationary temporal characterization temperature profile soil exposed to frost
2009/10/30
The objective of this work was to compare time and frequency fluctuations of air and soil temperatures (2-, 5-, 10-, 20- and 50-cm below the soil surface) using the continuous wavelet transform, with ...

Fracturing of the Crystalline Uppermost Crust Beneath the SVEKA Profile in Central Finland.
Deep Structure of the Earth's Crust Along the SVEKA Profile and its Extention to the North-East
lithosphere Earth’s crust gravity modeling density
2009/6/10
A new integrated seismic and density model along the SVEKA profile in Finland is presented. The model has been obtained as a result of application of non-traditional approach to gravity data inversion...
Discretization Independent Retrieval of Atmospheric Ozone Profile
University of Oulu,Department of Mathematical Sciences,FIN-90401 Oulu,Finland Sodankylä Geophysical Observatory,FIN-99600 Sodankylä ,Finland
2009/6/10
A simulation based study on the remote sensing problem of retrieving the atmospheric ozone
profile is performed so that the effects of the discretization error can be analyzed.
The retrieved profile...
A joint inversion of apparent resistivity and peak-period of microtremor horizontal-to-vertical spectrum for shallow soil profile
microtremors horizontal-to-vertical spectrum S-wave velocity vertical electrical sounding resistivity simulated annealing
2009/3/5
We propose a new technique for a joint inversion of apparent resistivity data from a vertical electrical sounding and peak-period of spectral ratio of horizontal microtremors to vertical one in order ...
Estimating the shear velocity profile of Quaternary silts using microtremor array (SPAC) measurements
microtremor method Rayleigh waves sediment thickness
2009/3/5
We have used the microtremor method, with arrays of up to 96 m diameter, to carry out non-invasive estimation of shear-wave velocity profiles to a depth of 30 to 50 m in unconsolidated Quaternary Yarr...
