Gravity inversion method using L0-norm constraint with auto-adaptive regularization and combined stopping criteria

MG Gebre, E Lewi - Solid earth, 2023 - se.copernicus.org
We present a gravity inversion method that can produce compact and sharp images to assist
the modeling of non-smooth geologic features. The proposed iterative inversion approach …

L0-norm gravity inversion with new depth weighting function and bound constraints

MG Gebre, E Lewi - Acta Geophysica, 2022 - Springer
Delineating geologic features through the inversion of gravity data is an important goal in a
range of geophysical investigations. However, it is a well-known fact that gravity data …

Hyperparameter determination for GAN-based seismic interpolator with variable neighborhood search

DN Pinheiro, JC Gonzalez, G Corso, MG Gebre… - Computers & …, 2024 - Elsevier
We propose an automatic global search algorithm based on the Variable Neighborhood Search
(VNS) metaheuristic for tuning the hyperparameters of a generative adversarial network (…

Seismic trace interpolation based on the principle of reciprocity using a conditional generative adversarial network (cGAN)

…, KDJ Rincon, DN Pinheiro, MG Gebre… - … of Geophysics and …, 2024 - academic.oup.com
Seismic trace interpolation is a common step in data processing used to fill in missing traces
and regularize acquisition grids. In the ocean bottom node (OBN) acquisition, it is common …

Implementation of a radiation protection system at four hospitals in Ethiopia

GM Geletu, F Abiko, S Sahlu - arXiv preprint arXiv:1905.07271, 2019 - arxiv.org
Diagnostic imaging procedure using ionizing radiation has been growing due to its enormous
benefits. However, using ionizing radiation is also associated with harmful biological …

[PDF][PDF] Tunnel Health Monitoring Using Seismics

MG Gebre - 2013 - duo.uio.no
In this thesis a new approach, called THEAMTM, is presented. The THEAMTM methodology
is a non-invasive tunnel health monitoring method using active seismic. The method …
