Evaluation of Philips and Ziegler-Natta high-density polyethylene degradation during processing in an internal mixer using the chain scission and branching distribution function analysis
(Elsevier B.V., 2006-10-01)
The oxidative and thermo-mechanical degradation of HDPE was studied during processing in an internal mixer under two conditions: totally and partially filled chambers, which provides lower and higher concentrations of ...

On laws of large numbers in L2 for supercritical branching Markov processes beyond λ-positivity
(Institute of Mathematical Statistics, 2019-02)
We give necessary and sufficient conditions for laws of large numbers to hold in L2 for the empirical measure of a large class of branching Markov processes, including λ-positive systems but also some λ-transient ones, ...
Efficiency of Different Chain-linking Agents in the Synthesis of Long-chain Branched Polypropylene. Molecular, Thermal and Rheological Characterization
(Taylor, 2017-09)
Long-chain branched polypropylenes were synthesized from a maleic anhydride grafted polypropylene (PPg). Different levels of branching were generated by reactive processing using four chain-linking agents: glycerol, ...
A branch-and-price approach to p-median location problems
(Elsevier B.V., 2005-06-01)
This paper describes a branch-and-price algorithm for the p-median location problem. The objective is to locate p facilities (medians) such as the sum of the distances from each demand point to its nearest facility is ...
