Joint species movement modeling: how do traits influence movements?
(2019-04-01)
Joint species distribution modeling has enabled researchers to move from species-level to community-level analyses, leading to statistically more efficient and ecologically more informative use of data. Here, we propose ...
Business model dynamics: a case survey
(Universidad de Talca, 2009)
Subjective modeling decisions can significantly impact the simulation of flood and drought events
(Elsevier B.V., 2019)
© 2018 The Author(s)It is generally acknowledged in the environmental sciences that the choice of a computational model impacts the research results. In this study of a flood and drought event in the Swiss Thur basin, we ...
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 ...
Basic ingredients for mathematical modeling of tumor growth in vitro: Cooperative effects and search for space
(2013-11-01)
Based on the literature data from HT-29 cell monolayers, we develop a model for its growth, analogous to an epidemic model, mixing local and global interactions. First, we propose and solve a deterministic equation for the ...
A note on model uncertainty in linear regression
(Blackwell Publ Ltd, 2003-01-01)
We consider model selection uncertainty in linear regression. We study theoretically and by simulation the approach of Buckland and co-workers, who proposed estimating a parameter common to all models under study by taking ...
Bayesian Analysis for Errors in Variables with Changepoint Models
(UNIV NAC COLOMBIA, DEPT ESTADISTICABOGOTA DC, 2012)
Changepoint regression models have originally been developed in connection with applications in quality control, where a change from the in-control to the out-of-control state has to be detected based on the avaliable ...
Infant mortality model for lifetime data
(ROUTLEDGE JOURNALS, TAYLOR & FRANCIS LTDLONDON, 2009)
In this paper we introduce a parametric model for handling lifetime data where an early lifetime can be related to the infant-mortality failure or to the wear processes but we do not know which risk is responsible for the ...
Properties of saturation in monotonic neighbourhood models and some applications
(Springer, 2015-08)
In this paper we shall discuss properties of saturation in monotonic neighbourhood models and study some applications, like a characterization of compact and modally saturated monotonic models and a characterization of the ...
Nonlinear Dynamic Average Model of a DC-DC Converter
(Institute Of Electrical And Electronics Engineers, 2014-08)
A nonlinear dynamical average model of a dc-dc converter is presented. The converter under study has a particular feature. In this converter, classical average analysis cannot be applied because the ripple cannot be neglected ...
