Controlled rheology of polypropylene: Modeling of molecular weight distributions
(John Wiley & Sons Inc, 2003-05)
A mathematical model for the controlled degradation of polypropylene is presented in this article. A previous model of this process was extended to predict the whole molecular weight distribution of the modified resin. ...
Peroxide modification of polyethylene. Prediction of molecular weight distributions by probability generating functions
(Elsevier, 2002-02-09)
We present a mathematical model able to describe the complete molecular weight distributions of polyethylene during reactive modification by organic peroxides. The method is applicable to batch processes, such as modification ...
Force-sensitive resistors to measure the distribution of weight in the pads of sound dogs in static standing position
(Faculty of Veterinary Sciences - Universidad Austral de Chile, 2022)
A COM–poisson type generalization of the binomial distribution and its properties and applications
(ElsevierAmsterdam, 2014-04)
Shmueli et al. (2005) introduced the COM–Poisson–binomial distribution, but they did not study the mathematical properties of this family of distributions. In this paper, we discuss some properties and an asymptotic ...
Prediction of the full molecular weight distribution in RAFT polymerization using probability generating functions
(Elsevier, 2014-07)
In this work, a model for the RAFT polymerization following the slow fragmentation approach was developed in order to obtain the full molecular weight distribution (MWD) using probability generating functions (pgf). A ...
The effect of maltose on dextran yield and molecular weight distribution
(SpringerNew YorkEUA, 2005)
High-pressure polymerization of ethylene in tubular reactors: A rigorous dynamic model able to predict the full molecular weight distribution
(Wiley VCH Verlag, 2009-09)
A rigorous dynamic model of the high-pressure polymerization of ethylene in tubular reactors is presented. The model is capable of predicting the full molecular weight distribution (MWD), average branching indexes, monomer ...
Modelo de mistura padrão com tempos de vida exponenciais ponderados
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Estatística - PPGEs, 2010-03-05)
In this work, we brie_y introduce the concepts of long-term survival analysis. We dedicated ourselves exclusively to the standard mixture cure model from Boag (1949) and Berkson & Gage (1952), showing its deduction and ...
