Three-dimensional quasi linear electromagnetic inversion [PDF]
, 1996 journal articleOne of the most challenging problems of electromagnetic (EM) geophysical methods is developing three-dimension(a3l- D) EM inversion techniques. This problem is of utmost importance in practical applications because of the 3-D nature of the

Deep Underground Science and Engineering, EarlyView.Aluminum‐enhanced afterburning renders AE explosives more hazardous than conventional ones. Corrugated steel linings reduce far‐field AE blast overpressure by ~50% through wave reflection and dissipation. The developed model accurately predicts peak pressure (<10% error) and arrival time (<3% error), supporting protective design.

Geology Matters for Antarctic Geothermal Heat
Geophysical Research LettersGeothermal heat plays a vital role in Antarctic ice sheet stability. The continental geothermal heat flow distribution depends on lithospheric composition and ongoing tectonism. Heat‐producing elements are unevenly enriched in the crust over deep time by

Localized S-inversion of time-domain electromagnetic data [PDF]
, 2002 journal articleInterpretation of time-domain electromagnetic (TDEM) data over inhomogeneous geological structures is a challenging problem of geophysical exploration.

Deep Underground Science and Engineering, EarlyView.The fused data extracted from the distributed monitoring system as the data basis, combined with dynamic geological data, are imported into a deep learning model. As the geological conditions of mining and excavation change, the risk of water inrush at the working face is retrieved in real time.

GEOLOGY OF PASSION: G.H.’S RETURN TO THE CAVE
Revista Brasileira de Literatura Comparada, 2023 The Passion according to G.H. is one of the texts most commented on by specialized critics. Since it is a classic text, that is, a book that can be read by each new generation from new entries, the present work attempts a reading of Clarice Lispector’s ...
