Our collaboration has resulted in a series of three papers on a new model for grain boundarydiffusion creep in partially molten rocks. The broad aim is to better understand the physical processes controlling the interactions of deformation, melt distribution and melt migration. Towards this aim, we saw the need for a 3-D, grain-scale model for viscosity in the presence of melt. The constitutive...

Political districting is an intractable problem with significant ramifications for political representation. Districts often are required to satisfy some legal constraints, but these typically are not very restrictive, allowing decision makers to influence the composition of these districts without violating relevant laws. For example, while districts must often comprise a single contiguous are...

DIVCLUS-T is a descendant hierarchical clustering algorithm based on a monothetic bipartitional approach allowing the dendrogram of the hierarchy to be read as a decision tree. We propose in this paper a new version of this method called C-DIVCLUS-T which is able to take contiguity constraints into account. We apply C-DIVCLUS-T to hydrological areas described by agricultural and environmental v...

Two experiments investigated the roles of contingency and temporal contiguity in causal reasoning, and the trade-off between them. Participants observed an ongoing, continuous stream of events, which was not segmented into discrete learning trials. Four potential candidate causes competed for explanatory strength with respect to a single dichotomous effect. The effect was contingent on two of t...

Trace conditioning, a form of classical conditioning in which the presentation of the conditioned stimulus (CS) and the unconditioned stimulus (US) is separated in time by an interstimulus interval, requires an intact hippocampus. In contrast, classical conditioning procedures in which the CS and US are not separated by an interstimulus interval (i.e., delay conditioning procedures) typically d...

We address a global constraint for enforcing contiguity. Contiguity is the property that all of one kind of object in an array or list are grouped together; it is a one-dimensional discrete form of convexity. We present an implementation of this property in a concurrent constraint programming language. We adapt and apply the constraint propagation framework of [19] to analyse the contiguity pro...

To the frequentist who computes posteriors, not all priors are useful asymptotically: in this paper, a Bayesian perspective on test sequences is proposed and Schwartz’s Kullback–Leibler condition generalised to widen range of applications posterior convergence. With tests weakened form contiguity termed remote contiguity, we prove simple fully general theorems, for consistency rates convergence...

Markov Processes Pankaj Kumar and ¤Kuntal Sengupta Department of Electrical and Computer Engineering, National University of Singapore 10 Kent Ridge Crescent, Singapore 119260 e-mail: [email protected] EDICS: 2-SEGM, 2-SEQP November 6, 2000 Abstract In this paper, we present a novel approach in extracting interesting foreground regions from a complex and largely stationary background scene. The ...

In recalling a set of previously experienced events, people exhibit striking effects of recency, contiguity, and similarity: Recent items tend to be recalled best and first, and items that were studied in neighboring positions or that are similar to one another in some other way tend to evoke one another during recall. Effects of recency and contiguity have most often been investigated in tasks...
