WebFactors determining Poisson’s ratio John J. Zhang and Laurence R. Bentley ABSTRACT Poisson’s ratio is determined by two independent factors, i.e., the solid rock and dry or wet cracks. The former is influenced by the constituent mineral composition. The higher Poisson’s ratio of the rock solid is, the higher is Poisson’s ratio of the rock. WebHere, we propose a new conjugate and numerically stable dynamic matrix factorization (DCPF) based on hierarchical Poisson factorization that models the smoothly drifting … WebDynamic Poisson Factor Analysis Abstract—We introduce a novel dynamic model for discrete time-series data, in which the temporal sampling may be nonuni-form. The model is speciﬁed by constructing a hierarchy of Poisson factor analysis blocks, one for the transitions between latent states and the other for the emissions between latent states grand toal
