Efficient modeling of distributions of polymer properties using probability generating functions and parallel computing
(Pergamon-Elsevier Science Ltd, 2019-09-02)
High-fidelity models of polymer processes should include the prediction of distributions of polymer properties, including multivariate distributions. Deterministic models with this capability usually involve a large system ...
Modeling of the bivariate molecular weight distribution-copolymer composition distribution in RAFT copolymerization using probability generating functions
(Elsevier Science, 2017-08)
In this work, we develop a mathematical model of a RAFT copolymerization process able to predict average molecular properties as well as the full bivariate molecular weight distribution – copolymer composition distribution ...
“Living” Free Radical Polymerization in Tubular Reactors. I. Modeling of the Complete Molecular Weight Distribution Using Probability Generating Functions
(Wiley VCH Verlag, 2007-11-15)
This is the first of a series of works aiming at developing a tool for designing “living” free radical polymerization processes in tubular reactors, in order to achieve tailor‐made MWDs. A mathematical model of the ...
LDPE Production in Tubular Reactors: Comprehensive Model for the Prediction of the Joint Molecular Weight-Short (Long) Chain Branching Distributions
(American Chemical Society, 2019-03)
Good control on molecular properties, and as a consequence on end-use properties, is very important for low-density polyethylene (LDPE) manufacturers. However, the connection between the architecture of polymer chains and ...
Estimation of combustion engine technical state by multidimensional analysis using SVD method
(Inderscience Enterprises Ltd., 2013-01-01)
The changes of vibration estimators as a result of engine maladjustment, waste, damage or failure are the main idea of vibrodiagnostic investigation. Diagnostic investigations that use vibration to determine the technical ...
A nonparametric nonstationary procedure for failure prediction
(Institute of Electrical and Electronics Engineers, 2002-12)
The time between failures is a very useful measurement to analyze reliability models for time-dependent systems. In many cases, the failure-generation process is assumed to be stationary, even though the process changes ...

Useful dual functional of entropic information measures
(Molecular Diversity Preservation International, 2020-04-24)
There are entropic functionals galore, but not simple objective measures to distinguish between them. We remedy this situation here by appeal to Born’s proposal, of almost a hundred years ago, that the square modulus of ...
