This paper discusses region-based representations useful to create connected operators. The filtering approach involves three steps: first, a region tree representation of the input image is constructed. Second, the simplification is obtained by pruning the tree and third, and output image is constructed from the pruned tree. The paper focuses in particular on several pruning strategies that ca...

We consider the descriptive complexity of some subsets of the infinite permutation group S∞ which arise naturally from the classical series rearrangement theorems of Riemann, Levy, and Steinitz. In particular, given some fixed conditionally convergent series of vectors in Euclidean space Rd, we study the set of permutations which make the series diverge, as well as the set of permutations which...

Purpose – The purpose of the paper is to critically evaluate membership of the FTSE4Good “socially responsible investment” indices (membership of which is based on ethical criteria), which were launched in the UK in July 2001 as a means of increased accountability and change. Design/methodology/approach – The paper adopts an interpretive and critical approach when examining the perceptions of c...

PURPOSE Cortisol awakening response (CAR) and nighttime cortisol levels have been used as indices of adrenocortical activity. However, population-based statistical information regarding these indices has not been provided in healthy subjects. This study was carried out to provide basic statistical information regarding these indices. MATERIALS AND METHODS Cortisol levels were measured in sali...

There is a growing need for abstractions in logic specification languages such as FO(·) and ASP. One technique to achieve these abstractions are templates (sometimes called macros). While the semantics of templates are virtually always described through a syntactical rewriting scheme, we present an alternative view on templates as second order definitions. To extend the existing definition cons...

BACKGROUND AND OBJECTIVES: Understanding the importance of surface electromyography as a complementary method to understand the myofunctional status of the stomatognathic system, this study aimed at analyzing the frequency of altered and normal electromyographic indices in a sample of subjects with temporomandibular disorders, in addition to their relation with pain complaint. METHODS: Particip...
