Tectonic inversion and magmatism in the Lautaro Basin, northern Chile, Central Andes: A comparative approach from field data and analog models
We present the results of a series of analog models addressing the relationships between tectonic inversion and magmatism, taking the Lautaro Basin in northern Chile (27-28 degrees S), Central Andes as a natural case. The ...
The generalized inverse Weibull distribution
The inverse Weibull distribution has the ability to model failure rates which are quite common in reliability and biological studies. A three-parameter generalized inverse Weibull distribution with decreasing and unimodal ...
Variable order smoothness priors for ill-posed inverse problems
(Amer Mathematical Soc, 2014-11)
In this article we discuss ill-posed inverse problems, with an emphasis on hierarchical variable order regularization. Traditionally, smoothness penalties in Tikhonov regularization assume a fixed degree of regularity of ...
Mathematical modeling of bivariate polymer property distributions using 2D probability generating functions, 1 - Numerical inversion methods
(Wiley VCH Verlag, 2010-08)
This is the first of two papers presenting a new mathematical method for modeling bivariate distributions of polymer properties. It is based on the transformation of the infinite mass balances describing the evolution of ...
Degradation modeling for reliability analysis with time-dependent structure based on the inverse gaussian distribution
(Universidade Federal de São CarlosUFSCarPrograma de Pós-graduação em Estatística UFSCar/USPCâmpus São Carlos, 2017-04-07)
Conventional reliability analysis techniques are focused on the occurrence of failures over time. However, in certain situations where the occurrence of failures is tiny or almost null, the estimation of the quantities ...
Role of basin width variation in tectonic inversion: insight from analogue modelling and implications for the tectonic inversion of the Abanico Basin, 328–348S, Central Andes
(Geological Society Of London, 2014-05)
We use analogue modelling to investigate the response of compressional deformation superimposed on an extensional basin with along-strike changes in width. Parameters described include extension and shortening distribution ...
A hybrid genetic-linear algorithm for 2D inversion of sets of vertical electrical sounding

Comparative study of the thermal fluctuations effects on the classical Stoner-Wohlfarth and analytical vector hysteron models
(Elsevier Science, 2014-03)
In this work we present a comparative study of the classical Stoner Wohlfarth model and the analytical vector hysteron model. We analyze the hysteretic behavior description when the thermal fluctuations are included. We ...
A non-default rate regression model for credit scoring
In this paper, we propose a new non-default rate survival model. Our approach enables different underlying activation mechanisms which lead to the event of interest. The number of competing causes, which may be responsible ...
