The stochastic quantization method and its application to the numerical simulation of volcanic conduit dynamics under random conditions
stochastic quantization method application to the numerical simulation volcanic conduit dynamics random conditions
2014/12/31
Stochastic Quantization (SQ) is a method for the approximation of a continuous probability distribution with a discrete one. The proposal made in this paper is to apply this technique to reduce the nu...

2014/12/24
We study the soft X-ray emission (0.1-1 keV) from the warm-hot intergalactic medium (WHIM) in a hydrodynamic simulation of a cold dark matter universe. Our main goal is to investigate how such emissio...
Computing the Bayes Factor from a Markov chain Monte Carlo Simulation of the Posterior Distribution
Markov chain Bayes Factor
