In this paper we present a parametric model for facial animation and a method for adapting it to a specific person. Every facial expression can be described as a contraction or relaxation of the facial muscles. P. Ekman and F.W. Friesen selected 44 Action Units corresponding to visual changes on the face, which cannot be decomposed into smaller ones and which combinations universally represent ...

Cure models are survival models basically developed to estimate the proportion of patients cured in a clinical trial. These models estimate the cured proportion and also the probability of survival. Cure models are a special type of survival analysis model where it is assumed that there are a proportion of subjects who will never experience the event and thus the survival curve will eventually ...

Relative survival is frequently used in population-based studies as a method for estimating disease-related mortality without the need for information on cause of death. We propose an extension to relative survival of a flexible parametric model proposed by Royston and Parmar for censored survival data. The model provides smooth estimates of the relative survival and excess mortality rates by u...

using a new numerical model, the pump-to-signal relative intensity noise (rin) transfer in singlepumpfiber optical parametric amplifiers for low modulation frequencies is investigated. the model includesfiber loss, pump depletion, as well as the gain saturation, and therefore, it can describe the practicalcircumstances associated with various applications of fiber optical parametric amplifiers....

We propose a decomposition of posterior variance somewhat in the spirit of an ANOVA decomposition. Terms in this decomposition come in pairs. Given a single parametric model, for instance, one term describes uncertainty arising because the parameter value is unknown while the other describes uncertainty propagated via uncertainty about which prior distribution is appropriate for the parameter. ...

We explore the inand outof sample robustness of tests for consumer choice inconsistencies based on parameter restrictions in parametric models, with a focus on tests proposed by Ketcham, Kuminoff and Powers (KKP). We start by arguing that their non-parametric alternatives are inherently conservative with respect to detecting mistakes. We then show that our parametric model is robust to KKP’s su...

b a c k g r o u n d & aim: in many studies, the survival of patients with chronic kidney disease who are treated with peritoneal dialysis technique has been considered, while this is possible in peritoneal dialysis  patients  to switch  to another  treatment.  to achieve  more  accurate  estimation  of patient survival is necessary to examine all events. the purpose of this study is to estimate...
