In this paper, a Bayesian hierarchical model is used to anaylze the female breast cancer mortality rates for the State of Missouri from 1969 through 2001. The logit transformations of the mortality rates are assumed to be linear over the time with additive spatial and age effects as intercepts and slopes. Objective priors of the hierarchical model are explored. The Bayesian estimates are quite ...

Petri nets are useful for modelling complex concurrent systems. While modelling using Petri nets focusses on local states and actions, the analysis methods are concerned with global states and their transitions. Unfortunately generation of the complete state space suffers from the well-known state space explosion problem. This paper presents a method to overcome the state-space explosion proble...

Time-dependent creep stress redistribution analysis of thick-walled FGM spheres subjected to an internal pressure and a uniform temperature field is investigated. The material creep and mechanical properties through the radial graded direction are assumed to obey the simple power-law variation throughout the thickness. Total strains are assumed to be the sum of elastic, thermal and creep strain...
