The design of intelligent agents is greatly influenced by the many different models that exist to represent knowledge. It is essential that such agents have computationally adequate mechanisms to manage its knowledge, which more often than not is incomplete and/or…

En este trabajo se presentan los resultados de los estudios zooarqueológicos realizados en el poblado de Nombre de Jesús (cabo Vírgenes, provincia de Santa Cruz, Argentina) establecido como parte del proyecto español de fortificación del Estrecho Magallanes a fines del…

We examine semantic interoperability problems in the fixed income securities industry
and propose a knowledge representation architecture for context interchange
mediation to support dynamic integration of autonomous database, web, and
procedural sources of information. For sources and…

Knowledge representation models are very important in the design of intelligent agents because they provide with mechanisms to manage beliefs and their dynamics. In this paper, we propose the use of AnsProlog* as a knowledge representation language, and develop a…

This study investigates an approach of knowledge discovery and data mining in insufficient databases. An application of Computational Taxonomy analysis demonstrates that the approach is effective in such a data mining process. The approach is characterized by the use ot…

//// Abstract: My purpose in this essay is to bring to light the role played by experience in the justification process of empirical knowledge. Contemporary debate is dominated by two antagonistic sides: on one extreme we have the foundationalist empiricists…

Micro embossing is the process of fabricating micron-sized features by plastic deformation of a work piece by means of a shaped tool or die. In our work we are concerned with hot embossing of PMMA to produce features in the…

ABSTRACT: Micronutrients availability is na important constraint for crops in the Cerrado region, and its correction is always needed to obtaining economic yields. Old and new nutritional problems came with the agriculture expansion in Cerrado. Although being crucial for increasing…

Although our biological knowledge regarding cactus species is thorough in many areas, only in recent years have ecologists addressed their demographic behavior. Here we attempt a first review of the present knowledge on cactus demography, including an analysis of the…
