In this paper, we present the CID system for learning concepts from a set of examples. These examples are represented as conjunctions of attributes and their values that may be precise or not completely deened. We propose a data representation to take into account struc-tured attributes and values that may be 'impossible', 'un-known' or 'imprecise'. Lattice of fuzzy qualiiers are used to modeli...

In categorial systems with a fixed structural component, the learning problem comes down to finding the solution for a set of typeassignment equations. A hard-wired structural component is problematic if one want to address issues of structural variation. Our starting point is a type-logical architecture with separate modules for the logical and the structural components of the computational sy...

This paper presents a variant of a probabilist approach to motion planning. The objective is to face large, complex industrial environments for maintenance purpose. The contribution is based on a struc-turing of the workspace into boxes that limits the size of the graph to be searched. The algorithm was integrated in a commercial CAD system and real-size experiments are presented.

Elemental phosphorus has been known for about 350 years. As a result of huge scientific interest, numerous textbooks are filled with information about this element, its different allotropes, and its compounds. [1] Like boron and carbon, the element features tremendous structural variability, resulting in great diversity of physical properties and chemical reactivity: White phosphorus, P4, forms...

AIM Insufficient research examines the treatment effectiveness of real-world physical activity (PA) interventions. PURPOSE We investigated the effects of 3 interventions on directly measured cardiovascular variables. All treatments and measures were administered in community settings by fitness centre staff. METHODS Participants were sedentary individuals receiving no medication to reduce c...

Hierarchical organisation is omnipresent in natural systems and is of special importance in connection with living systems. Thus far it is poorly understood what type of artificially created system is capable of replicating the emergent hierarchical structure of nature. This paper is an attempt to clarify what hierarchical struc-
