Although researchers noted the importance of effective communication among stakeholders, it continues to be a challenge for requirements engineering. Communication can be considered as a management tool since communication allows organisation’s personnel to produce a cohesive enterprise view. In this…

Data base management evolved during the sixties and seventies. The evolution period was protracted. Many driving forces impacted the evolution and it is the aim of this paper to analyze these driving forces (some technical and some political) and to…

Today software solutions are often modeled using UML. Design patterns are frequently instantiated within these particular solutions. However, in several situations, UML is not expressive enough to describe them properly.
UML profiles extend UML syntax and semantic in order to…

A pesar de la reciente disminución de la mortalidad, la enfermedad cardiaca coronaria continúa siendo la principal causa de muerte en EEW. La mayoría de estas muertes ocurren súbitamente y fuera del hospital. Hay evidencias de que la reanimación cardiopulmonar…

The application of ANNs (Artifi cial Neural Networks) has been studied by many researchers in modelling rainfall runoff processes. However, the work so far has been focused on the rainfall data from traditional raingauges. Weather radar is a modern technology…

El crecimiento continuo de la Internet ha permitido a las personas, alrededor de todo mundo, realizar transacciones en línea, buscar información o navegar usando el explorador de la Web. A medida que más gente se siente cómoda usando los exploradores…

The genetic algorithms have seen applied in knowledge discovery and specially for discovering association rules. In this paper, we explore the use of di erent rule quality measures in the tness function in a genetic algorithm for discovering association rules.…

Manipulating and retrieving multimedia data has received increasing attention with the advent of cloud storage facilities. The ability of querying by similarity over large data collections is mandatory to improve storage and user interfaces. But, all of them are expensive…

Clustering of short texts is an important research area because of its applicability in information retrieval and text mining. To this end was proposed CLUDIPSO, a discrete Particle Swarm Optimization algorithm to cluster short texts. Initial results showed that CLUDIPSO…
