Hitting Times and Probabilities for Imprecise Markov Chains [article]

Thomas Krak, Natan T'Joens, Jasper De Bock
2020 arXiv   pre-print
Our first contribution is that all these different types of imprecise Markov chains have the same lower and upper expected hitting times, and similarly the hitting probabilities are the same for these  ...  We consider the problem of characterising expected hitting times and hitting probabilities for imprecise Markov chains.  ...  We are very grateful to three anonymous reviewers for their helpful suggestions and constructive comments.  ...

An Integrated Procedure for Bayesian Reliability Inference Using MCMC

Jing Lin
2014 Journal of Quality and Reliability Engineering  
The recent proliferation of Markov chain Monte Carlo (MCMC) approaches has led to the use of the Bayesian inference in a wide variety of fields.  ...  The goal is to build a framework for related academic research and engineering applications to implement modern computational-based Bayesian approaches, especially for reliability inferences.  ...  Acknowledgments The author would like to thank Luleå Railway Research Centre (Järnvägstekniskt Centrum, Sweden) for initiating the research study and Swedish Transport Administration (Trafikverket) for  ...

This exercise yields an internal rate of return of 0.032.  ...  Hence, the calculated internal rate of return is an upper bound as our estimated effects on income are valid only for every tenth tested person.  ...

Borel on the Heap

Paul Égré, Anouk Barberousse

Metastability of hard-core dynamics on bipartite graphs [article]

Frank den Hollander, Francesca R. Nardi, Siamak Taati
2017 arXiv   pre-print
We obtain a sharp asymptotic estimate for the expected transition time, show that the transition time is asymptotically exponentially distributed, and identify the size and shape of the critical droplet  ...  For various types of bipartite graphs the computations are made explicit. Proofs rely on potential theory for reversible Markov chains, and on isoperimetric results.  ...  Therefore, we get a similar lower bound for the expected crossover time using Proposition 3.2. Proposition 8.4 (Lower bound for expected crossover time: Widom-Rowlinson).  ...

Dynamics of the Tidal Fields and Formation of Star Clusters in Galaxy Mergers [article]

Florent Renaud (Observatoire de Strasbourg and Institut für Astronomie, Vienna)
2010 arXiv   pre-print
In interacting galaxies, strong tidal forces disturb the global morphology of the progenitors and give birth to the long stellar, gaseous and dusty tails often observed.  ...  Furthermore, characteristic time- and energy scales of these modes match well those of self-gravitating substructures such as star clusters and tidal dwarf galaxies.  ...  This can be interpreted by considering the birth and death rates of the clusters.  ...
