A log-extended Weibull regression model
(ELSEVIER SCIENCE BV, 2009)
A bathtub-shaped failure rate function is very useful in survival analysis and reliability studies. The well-known lifetime distributions do not have this property. For the first time, we propose a location-scale regression ...
Methodology For Production Histry Matching Of Petroleum Fields Utilizing Logging Saturation Data
(Society of Petroleum Engineers, 2008)
Automatic well tying and wavelet phase estimation with no waveform stretching or squeezing
(Society of Exploration Geophysicists, 2020-02)
Well-to-seismic tie and wavelet phase estimation are close and related steps to link geology and seismic data. Usually these processes are solved separately or alternately, diminishing the quality of the well tying procedure. ...
Hydraulic parameters estimation from well logging resistivity and geoelectrical measurements
(Elsevier Science, 2014-06)
In this paper, a methodology is suggested for deriving hydraulic parameters, such as hydraulic conductivity or transmissivity combining classical hydrogeological data with geophysical measurements. Estimates values of ...
Influence diagnostics for polyhazard models in the presence of covariates
(SPRINGER HEIDELBERG, 2008)
In this paper, we present various diagnostic methods for polyhazard models. Polyhazard models are a flexible family for fitting lifetime data. Their main advantage over the single hazard models, such as the Weibull and the ...
Humboldtian diagnosis of peach tree (Prunus persica) nutrition using machine-learning and compositional methods
(2020-06-01)
Regional nutrient ranges are commonly used to diagnose plant nutrient status. In contrast, local diagnosis confronts unhealthy to healthy compositional entities in comparable surroundings. Robust local diagnosis requires ...
Enriquecimento semântico de logs como auxílio no processo de gestão e tomada de decisões
