A great deal of research has now established that written texts embody interactions between writers and readers, but few studies have examined the ways that small acts of reformulation and exemplification help contribute to this. Abstraction, theorisation and interpretation need to be woven into a text which makes sense to a particular community of readers, and this invariably involves frequent...

When intelligent systems are deployed into a real-world application, then the maintenance and the refinement of the knowledge are essential tasks. Many existing automatic knowledge refinement methods only provide limited control and clarification capabilities during the refinement process. In this paper, we present a novel user-guided approach for the refinement of knowledge bases using subgrou...

In recent years, enterprise architecture (EA) management has gained increasing attention as means to support enterprises in adapting to changing markets and in seizing new business opportunities. A multitude of approaches and frameworks making prescriptions on how to document the different states of the EA have been developed. These approaches target different purposes and correspondingly diffe...

This tutorial is intended to give an accessible introduction to Hopf algebras. The mathematical context is that of representation theory, and we also illustrate the structures with examples taken from combinatorics and quantum physics, showing that in this latter case the axioms of Hopf algebra arise naturally. The text contains many exercises, some taken from physics, aimed at expanding and ex...

This article summarizes research from an ecological dynamics program of work on team sports exemplifying how small-sided and conditioned games (SSCG) can enhance skill acquisition and decision-making processes during training. The data highlighted show how constraints of different SSCG can facilitate emergence of continuous interpersonal coordination tendencies during practice to benefit team g...

We estimate the variance parameter of a stationary simulation-generated process using a linear combination of overlapping standardized time series (STS) area variance estimators based on different batch sizes. We establish the linear-combination estimator’s asymptotic distribution, presenting analytical and simulation-based results exemplifying its potential for improvements in accuracy and com...

Uncertainties in the decision making of reliability centered maintenance (RCM) are discussed. These uncertainties might be unacceptable in many practical applications, leading to non-optimum maintenance strategies. An alternative approach, opening for speci®ed uncertainties is shown to correct this defect. Exemplifying the approach, a simple ®re detection system is discussed. q 2001 Elsevier Sc...
