State-dependent Foster–Lyapunov criteria for subgeometric convergence of Markov chains
We consider a form of state-dependent drift condition for a general Markov chain, whereby the chain subsampled at some deterministic time satisfies a geometric Foster-Lyapunov condition. We presentExpand

Perfect Simulation of $M/G/c$ Queues
TLDR
In this paper we describe a perfect simulation algorithm for the super-stable $M/G/c$ queue operating under First Come First Served discipline, exploiting Wolff's sample path monotonicity, for which a dynamic reversibility property holds. Expand

Optimal co-adapted coupling for the symmetric random walk on the hypercube
Let X and Y be two simple symmetric continuous-time random walks on the vertices of the n-dimensional hypercube, Z2n. We consider the class of co-adapted couplings of these processes, and describe anExpand

Correction. Perfect simulation for a class of positive recurrent Markov chains
In [1] we introduced a class of positive recurrent Markov chains, named tame chains. A perfect simulation algorithm, based on the method of dominated CFTP, was then shown to exist in principle forExpand

Separation and coupling cutoffs for tuples of inde- pendent Markov processes
We consider an n-tuple of independent ergodic Markov processes, each of which converges (in the sense of separation distance) at an exponential rate, and obtain a necessary and sufficient conditionExpand

Mixing times for exclusion processes on hypergraphs
We introduce a natural extension of the exclusion process to hypergraphs and prove an upper bound for its mixing time. In particular we show the existence of a constant $C$ such that for anyExpand

When to Switch? Index Policies for Resource Scheduling in Emergency Response
TLDR
This study considers the scheduling of limited resources to a large number of jobs (e.g., medical treatment) with uncertain lifetimes and service times, in the aftermath of a mass casualty incident. Expand

Mixing Time and Cutoff for a Random Walk on the Ring of Integers mod $n$
We analyse a random walk on the ring of integers mod $n$, which at each time point can make an additive `step' or a multiplicative `jump'. When the probability of making a jump tends to zero as anExpand

Deep Corrosion Assessment for Electrical Transmission Towers
TLDR
We propose a framework employing multiple deep neural networks based classifiers and detectors to perform automatic image-based condition monitoring for steel transmission towers. Expand
OPTIMAL CO-ADAPTED COUPLING FOR THE SYMMETRIC
Let X and Y be two simple symmetric continuous-time random walks on the vertices of the n-dimensional hypercube, Z n . We consider the class of coadapted couplings of these processes, and describe anExpand
