The aim of this paper is to present an R library, called tdc.msm, developed to analyze multi-state survival data. In this library, the time-dependent regression model and multi-state models are included as two possible approaches for such data. For the multi-state modelling five different models are considered, allowing the user to choose between Markov and semi-Markov property, as well as

Письменные источники - это документы, с которыми связана история как наука. Документы истории и история документов тесно переплетены. Автоматический контент-анализ и компьютерная обработка исторических текстов обрели свое собственное место в мире методов источниковедения и конкретно-исторического анализа.

We explore T-splines, a generalization of NURBS enabling local refinement, as a basis for isogeometric analysis. We review T-splines as a surface design methodology and then develop it for engineering analysis applications. We test... more

We explore T-splines, a generalization of NURBS enabling local refinement, as a basis for isogeometric analysis. We review T-splines as a surface design methodology and then develop it for engineering analysis applications. We test T-splines on some elementary two- dimensional and three-dimensional fluid and structural ana lysis problems and attain good results in all cases. We summarize current limitations and
