This work makes a comparative study between four methods for extreme values estimation of non-Gaussian time series. The methods studied are: Hermite Moment Model, Shifted Generalized Lognormal Distribution (SGLD), Average Conditional Exceedance Rates (ACER) and Weibull Distribution Model. In the ...

Shale deposits are the main sources of oil and natural gas, because they contain the organic content that, under special conditions, originates hydrocarbons. The main technique used in the oil industry for the discovery of hydrocarbon deposits is reflection seismic, although there have&...

The use of mining wastes in another productive chain is a sustainable way of minimizing the environmental damages caused by the mining activity. Civil construction, by consuming large quantities of natural materials, emerges as a potential alternative for the use of these wastes. T...

Recycled aggregate of concrete (RAC) presents different characteristics from the natural aggregates because it is formed by part of natural aggregate with attached mortar around. This difference directly affects its properties and consequently the concretes produced with. Thus, for the rational&#...

Anisotropy caused by fractures is a major cause of uncertainties in projects for borehole perforation, since fractures may become pathway for fluid flow or even create barriers during oil production. This issue can be dealt with via seismic anisotropy investigation to map fracture ...

Debris flows are the most difficult landslide to be predicted and they can cause catastrophic lost. The use of protection structures, in most of the areas that are susceptible to the occurrence of debris flows, is the most appropriate intervention for the safety of human ...
