New Magnetic Anomaly Map of the East Asia with Some Preliminary Tectonic Interpretations

open access: yesTerrestrial, Atmospheric and Oceanic Sciences, 2015
Magnetic data provides basic information for geological and geophysical interpretation. In this study we compile recently collected (57 cruises survey) and old (published and open access) magnetic data.

Ore deposit exploration, geophysics and cutoff grade [PDF]

open access: yesMineral Exploration, 2018, 2018
Geophysics testing has always been the most available and affordable information for large scale mineral exploration. This paper uses the geophysics conditions of recent mines to build a model on ore locations. The model will also provide information for cutoff grid.

Quantization‐Based Latin Hypercube Sampling for Dependent Inputs With an Application to Sensitivity Analysis of Environmental Models

open access: yesApplied Stochastic Models in Business and Industry, EarlyView.
ABSTRACT Numerical models are essential for comprehending intricate physical phenomena in different domains. To handle their complexity, sensitivity analysis, particularly screening is crucial for identifying influential input parameters. Kernel‐based methods, such as the Hilbert‐Schmidt Independence Criterion (HSIC), are valuable for analyzing ...

Geophysical investigation of earth dam using the electrical tomography resistivity technique

open access: yesREM: International Engineering Journal
Dams are structures that dam rivers and streams for a variety of purposes. These structures often need to be sturdy to withstand the force of the impoundment and the high values of accumulated water load.

The Performance of Altimeter Waveform Retrackers at Lake Baikal

open access: yesTerrestrial, Atmospheric and Oceanic Sciences, 2013
At each of five fixed locations along the ground tracks of JASON-1 and ENVISAT, a repeat-track analysis of 1-Hz sea surface height (SSH) data has been conducted to assess the performance of waveform retrackers over Lake Baikal in Siberia, Russia.
