In 'The Structure and Content of Truth" Davidson proposes to adopt an intermediate position between realist and epistemic theories. It is our opinion that this adoption is not a change of his previous views but that he had already anticipated…

The tools for fault impact analysis are important for the deployment of critical mission systems. These tools can be also used as a development phase aid. We introduce several concepts related to "business alarms". Business alarms are an approximation to…

In this work, we discuss aspects of a framework to support the understanding and the improvement in hypermedia development processes. The framework is built taking into account two modeling approaches and four domain levels. The modeling approaches are called prescriptive…

The creation of a stone fruit, pear and citrus integrated pest management (IPM) interdisciplinary network (entomology, and field and post-harvest pathology) to strengthen the exchange of knowledge and experiences of participating working groups is proposed; emphasizing on the development of…

This thesis studies al-Ghazali's theory of knowledge, particularly his concept of knowledge of God in his three later works: "The book of Knowledge" of the Ih&dotbelow;ya', al-Munqidh, and Iljam al-`Awamm. From his conception of knowledge of God the first book…

It is commonly acknowledged that we need to accept and handle uncertainty when reasoning with real world data. The most profoundly studied measure of uncertainty is the probability. However, the general feeling is that probability cannot express all types of…

This paper presents a new approach to reduce the space problem due to combinatorial explosion of CNM (Combinatorial Neural Model) method. First we show a description of CNM, proposed by Machado and Rocha [MAC 91], [MAC 92], [MAC 92a], [MAC…

Negative information can be represented in several classes of logic programs. These approaches were first motivated by the search for an appropriate declarative semantics for negation as failure. Recently, some formalizations of monotonic negation were also introduced in logic programming…

Belief Revision systems are logical frameworks to modeling the dynamics of knowledge. That is, how to modify our beliefs when we recieve new information. The main problem arises when the information is inconsistent with beliefs that represents our epistemic state.…

In a defeasible argumentation formalism, an argument is used as a defeasible reason for supporting conclusions. A conclusion q will be considered valid only when the argument that supports it become a justification. Building a justification involves the construction of…
