Integration of multiple geophysical data is a key practice to reduce model uncertainties and enhance geological interpretations. Electrical resistivity models resulting from inversion marine magnetotelluric (MT) data, often lack depth resolution lithological boundaries distinct information for shallow parts. This due the diffusive nature electromagnetic fields, enhanced by deficient sampling re...

OBJECTIVE Respiratory muscle weakness is a functional repercussion of chronic lung disease (CLD). The objective of this study was to assess the effects of home-based respiratory muscle training (RMT) in children and adolescents with CLD or neuromuscular disease (NMD). METHODS This was a quasi-experimental study involving children and adolescents with CLD or NMD. Before and after 6 months of h...

Abstract Magnetotelluric (MT) data are often distorted by near-surface small-scale lateral heterogeneities. Inverting MT may produce artifacts or false anomalies, leading to unreliable interpretation. This problem can be avoided inverting the phase tensor (PT), which is known free of galvanic distortion. However, PT inversion strongly depend on initial prior model, because itself does not conta...

Abstract Previous studies in Gondang Subdistricthave identified underground mud reservoirnear a rock intrusion, while another study near Subdistrict has deep fault structures. This will identify the distribution and characteristics of possible geological features area using magnetotelluric (MT) method to further describe relationship between related local geology. MT data measurements were cond...

In this work, we apply multi-temporal 1D-magnetotelluric (MT) surveys to estimate the space–time variations of apparent resistivity ρa and correlate these changes with seismic activity in central part Colombia (South America). We use time series Earth’s natural electric magnetic fields registered at two MT stations National University Seismological Network (RSUNAL), located Eastern Andean Cordi...

The geoelectric properties of the geothermal system associated with Tolhuaca volcano were investigated by three-dimensional (3D) inversion magnetotelluric (MT) data. This study presents first resistivity model derived from 3D MT to have a better understanding its magmatic and hydrothermal system. We selected data 54 stations for inversion. performed series tests changing type be inverted, as we...

The method of Hybrid Adaptive Filtering (HAF) aims to recover the recorded electric field signals from anomalies of magnetotelluric origin induced mainly by magnetic storms. An adaptive filter incorporating neuro-fuzzy technology has been developed to remove any significant distortions from the equivalent magnetic field signal, as retrieved from the original electric field signal by reversing t...
