The purpose of this article is to present a novel method for region based image watermarking that can tolerate local image distortions to a substantially greater extent than existing methods. The first stage of the method relies on computing a normalized version of the original image using image moments. The next step is to extract a set of feature points that will act as centers of the waterma...

This paper proposes a way to address the quantitative description of decision strategies for expert decision-makers in order to take into account the effects of personality, emotion or mood on decision-making. Most of common taxonomies used in popular models to decribe user profiles and behaviors seem to be difficult to apply in empirical cases. Instead we propose to rely on computational model...

Intuitively absurd but logically consistent sets of statements are common in publicly available OWL datasets. This article proposes an original and fully automated method to point at erroneous axioms in a consistent OWL knowledge base, by weakening it in order to improve its compliance with linguistic evidence gathered from natural language texts. A score for evaluating the compliance of subbas...

This paper describes a suite of extensions to the object oriented model, steering OO programming towards the Agent Programming paradigm; such set of extensions is called Agent Programming eXtensions (APX). APX has been specifically designed to leverage the development of agent-based systems, a widely adopted paradigm to model complex and dynamic software systems. A brief survey of the most comm...

Nutritional science relies on accurate dietary assessment. In observational studies of nutrition and health as well as dietary intervention, it is essential that dietary intakes are determined with sufficient accuracy to allow correct classification or compliance assessment. Although dietary instruments based on recalls, interviews, diaries, and questionnaires have been refined extensively in t...

Hierarchical image segmentation provides a set of image segmentations at different detail levels in which coarser details levels can be produced by simple merges of regions from segmentations at finer detail levels. However, many image segmentation algorithms relying on similarity measures lead to no hierarchy. One of interesting similarity measures is a likelihood ratio, in which each region i...

Four-wave-mixing processes enabled during optical wave-breaking (OWB) are exploited in this paper for supercontinuum generation. Unlike conventional approaches based on OWB, phase-matching is achieved here for these nonlinear interactions, and, consequently, new frequency production becomes more efficient. We take advantage of this kind of pulse propagation to obtain numerically a coherent octa...

According to the business literature, one can classify a social organization relying on a set of wellknown structural features. Depending on the values taken by each of these features, one can conclude whether the type of a specific organization is functional, divisional, hybrid, matrix-like, or processoriented. The organization type has strong influence upon the way business processes are exec...

Cardiac troponin (cT) is released after myocardial damage. In the appropriate clinical setting, a measured elevation of cT can increase the diagnostic rate of myocardial infarction and acute coronary syndrome. Elevations of cT, however, can occur in a wide variety of other clinical situations. Failure to recognize this can lead to an over-diagnosis of myocardial infarction (MI). We present clin...
