In the hot compression test friction has a detrimental influence on the flow stress through the process and therefore, correcting the deformation curve for real behavior is very important for both researchers and engineers. In this study, a series of compression tests were simulated using Abaqus software. In this study, it has been employed the Taguchi method to design experiments by the factor...

Robust statistics is an extension of classical parametric statistics that specifically takes into account the fact that the assumed parametric models used by the researchers are only approximate. In this article, we review and outline how robust inferential procedures may routinely be applied in practice in the biomedical research. Numerical illustrations are given for the t-test, regression mo...

decline curve analysis has some advantages over transient well test analysis in which it is not required to shut-in the well and also wellbore storage effects do not exist. few studies have been done on decline curve analysis of naturally fractured reservoirs but there are even some limitations with available models. on the other hand well test could be expensive and in some operational conditi...

In this paper we describe the participation of TELECOM ParisTech in the Large Scale Visual Concept Detection and Annotation Task at the ImageClef 2009 challenge. This year, the focus was in the extension of (i) the amount of data available for training and testing, and (ii) the number of concepts to be annotated. We use Canonical Correlation Analysis in order to infer a latent space where text ...

this review provides the basic principle and rational for roc analysis of rating and continuous diagnostic test results versus a gold standard. derived indexes of accuracy, in particular area under the curve (auc) has a meaningful interpretation for disease classification from healthy subjects. the methods of estimate of auc and its testing in single diagnostic test and also comparative studies...
