Linkage Based Dirichlet Processes
… Chain Monte Carlo (MCMC) algorithms for large parameter spaces. Dirichlet Process Mixture Models (DPMMs) have become a Bayesian mainstay for modeling heterogeneous structures, namely clusters, especially when the quantity of clusters is not known with the established MCMC methods. As opposed to …

Applications and Computation of Stateful Polya Trees
… than modeling a discrete distribution over parameters of a mixing kernel to obtain an absolutely continuous distribution. The Polya tree discretizes the state space with a recursive partition, generating a distribution by assigning mass to the child elements at each level of the recursive …

Time Series Models for Finance and the Environment
… It introduces a dynamic DCS model for the shape parameter that governs the tail index based on the Generalised t family of conditional distributions. The model also allows for asymmetry with different dynamics for the left and right tail index parameters. In addition the chapter introduces and …

Molecular simulation of liquid crystal polymer flow : a wavelet-finite element analysis
… of a limit point in the plot of structure parameter S vs. concentration parameter N, beyond which time-periodic solutions are the only stable solutions. At low De, the time-periodic solutions onset as tumbling states at a global bifurcation. At high De, they onset as wagging states at a …

Computational studies of viscoelastic multiphase flows
… flows. The roles of the governing dimensionless parameters: Capillary number (Ca), Deborah Number (De) and the polymer concentration parameter c, in determining deformation of drops and bubbles, are also analyzed. The numerical code permits us to vary Ca, De and c independently, which is …

Models of the Galaxy and the massive spectroscopic stellar survey RAVE
… model that performs well when individual parameter distribution are considered, but fails when we study chemodynamic correlations. The other two models are based on distributions of mass particles instead of analytical distribution functions. This is the first time that such models are …

Simulations of Galaxy Formation and Large Scale Structure
… object and find weak correlations of the spin parameter and the concentration parameter with the local halo density. We find no such correlation for the halo shapes, the formation time and the last major merging event. In a second step we produce catalogues of model galaxies using a …
