What exactly can we say about the dependency between artifact A and process P? Can we say that A was in fact generated by P, or was A generated by another process Q which used an artifact B that was generated by P? In fact, we cannot be sure. In particular, the given provenance information is insufficient to describe unambiguously in which order some basic OPM events (i.e., start of P, creation...

Operational failures in centrifuge pumps could be hydraulic or mechanical. However, most of these mechanical and hydraulic failures are connected cause of their operational nature and finding the right cause is due to considering numerous mechanical and hydraulic signs and parameters in pumps. On the other hand, due to non-linear and fluctuant behavior of pumps in the matter of time and not pre...

Given a real number t > 1, a geometric t-spanner is a geometric graph for a point set in R with straight lines between vertices such that the ratio of the shortest-path distance between every pair of vertices in the graph (with Euclidean edge lengths) to their actual Euclidean distance is at most t. An imprecise point set is modeled by a set R of regions in R. If one chooses a point in each reg...

We develop an efficient algorithm that calculates the maximal state sequences in an imprecise hidden Markov model by means of coherent lower previsions. Initial results show that this algorithm is able to robustify the inferences made by a classical precise model. Keywords— Imprecise hidden Markov model, coherent lower prevision, epistemic irrelevance, maximal state sequence, Viterbi algorithm.

In this paper, we propose an adaptation of the Parzen Rosenblatt cumulative distribution function estimator that uses maxitive kernels. The result of this estimator, on every point of the domain of F , the cumulative distribution to be estimated, is interval valued instead of punctual valued. We prove the consistency of our approach with the classical Parzen Rosenblatt estimator, since, accordi...
