Effect of Crystal Polymorphism on Elastic Modulus and Hardness of Poly(Butylene 2,6‐Naphthalate) (PBN)

open access: yesPolymer Engineering &Science, EarlyView.
The research provides insight into the mechanical behavior of the high‐performance polyester Poly(Butylene 2,6‐Naphthalate) containing different crystal polymorphs, adjustable by the conditions of melt‐crystallization. ABSTRACT The modulus of elasticity and hardness of poly(butylene 2,6‐naphthalate) (PBN) were investigated at different length scales ...

A generalized Poisson-gamma model for spatially overdispersed data

open access: yesSpatial and Spatio-temporal Epidemiology, 2012
Modern disease mapping commonly uses hierarchical Bayesian methods to model overdispersion and spatial correlation. Classical random-effects based solutions include the Poisson-gamma model, which uses the conjugacy between the Poisson and gamma ...

Characteristics-based heuristics to select a logical distribution between the Poisson-gamma and the Poisson-lognormal for crash data modelling

Transportmetrica A: Transport Science, 2019
Several studies have shown that the Poisson-lognormal (PLN) offers a better alternative compared to the Poisson-gamma (PG) when data are skewed while the PG is a more reliable option otherwise.
