In possibility theory, the degree of inconsistency is commonly used to measure the level of conflict in information from multiple sources after merging, especially conjunctive merging. However, as shown in [HL05,Liu06b], this measure alone is not enough when pairs of uncertain information have the same degree of inconsistency, since it is not possible to tell which pair contains information tha...

The problem of assessing the value of a can­ didate is viewed here as a multiple combi­ nation problem. On the one hand a candi­ date can be evaluated according to different criteria, and on the other hand several ex­ perts are supposed to assess the value of can­ didates according to each criterion. Criteria are not equally important, experts are not equally competent or reliable. Moreover lev...

Based on the transformative learning theory, it was sought to develop a procedure for helping teachers develop professionally. 13 elementary school teachers in one of the boys schools in Tehran’s district one participated in a workshop consisting of ten sessions and then interviewed. The content of the sessions was drawn from the theoretical basis of the study. Further field observations led to...

in a broader context of arguing against the view that conceivability provides epistemic access to the metaphysical modalities. His goal is “to identify the sources and forms of our knowledge of metaphysical possibility and metaphysical necessity” (205). 1 The account proceeds in two stages. First, he contends that “metaphysical necessity and metaphysical possibility can be reductively explained...

If an agent desires that φ and desires that ψ, this agent often also desires that φ and ψ hold at the same time (φ∧ψ). However, there are cases where φ ∧ ψ may be found less satisfactory for the agent than each of φ or ψ alone. This paper is a first attempt at modeling such nonmonotonic desires. The approach is developed in the setting of possibility theory, since it has been recently pointed o...

Preferences and uncertainty occur in many real-life problems. The theory of possibility is one non-probabilistic way of dealing with uncertainty, which allows for easy integration with fuzzy preferences. In this paper we consider an existing technique to perform such an integration and, while following the same basic idea, we propose various alternative semantics which allow us to observe both ...

A fuzzy morphological approach is here presented to retrieve structural properties of images considered as fuzzy sets. The basic concepts of the possibility theory and of the mathematical morphology are brieey illustrated, together with their suggested integration. Some applications to astronomical images are also shown.
