Natural language understanding systems require a knowledge base provided with formal representations reflecting the structure of human beings' cognitive system. Although surface semantics can be sufficient in some other ...

"The steel industry faces increasing challenges in managing product diversity, maintaining competitiveness, and improving operational efficiency. Within this context, recommendation systems present a promising opportunit...

This paper presents the interval arithmetic in a vector processing environment and its applicatioh in order to solve real problerns of science and engineering. Thus, we propose a computational tool, libavi.a, including i...

Information Retrieval Systems normally deal with keywordbased technologies. Although those systems reach satisfactory results, they aren’t able to answer more complex queries done by users, especially those directly in...

The distributed coordination and control of a team of autonomous mobile robots is a problem widely studied in a variety of elds, such as engineering, arti cial intelligence, arti cial life, robotics. Generally, in thes...

The resolution of optimization problems is of great interest nowadays and has encouraged the development of various information technology methods to attempt solving them. There are several problems related to Software E...

A atividade de teste constitui uma fase de grande importância no processo de desenvolvimento de software, tendo como objetivo garantir um alto grau de confiabilidade nos produtos desenvolvidos. Com o advento do paradigm...

Patterns are powerful tools to document software problems and their solutions, as well as when and how to use them. They can help improve software reuse. The implementation of non functional requirements, such as atomici...

A atualização dinâmica de sistemas é uma atividade crucial em software para missão crítica, que não pode parar a sua execução a qualquer momento. O presente artigo aborda aspectos sobre atualização de componen...

The objective of this paper is the construction of an Essential Object Model for Information Systems. This model is derived from the organization workflows representing the business processes and follows rules described ...

We propose an architecture-driven design approach based on the concept of proto-frameworks, aiming to provide an intermediate stage in the transition from architectural models to object-oriented frameworks or application...

Public key cryptography has been contributed some important functionality to computer systems security. Each pubic key scheme is based in some mathematics or computational problem, easy to solve in one way (an intended r...

Numerical Taxonomy aims to group in clusters, using so-called structure analysis of operational taxonomic units (OTUs or taxons or taxa) through numerical methods. These clusters constitute families. Structural analysis...
