As a contribution to consider software projects to be risk investments, it is important the full standardization of either the planning methodology (as a subset of project management methodology) and the effort estimation method. We think there is important and…

En los últimos años se ha elevado el número de personas que quieren aprender español como segunda lengua/lengua extranjera. Porello, es importante estudiar las dificultades que tienen que afrontar los estudiantes no nativos de español al momento de involucrarse en…

Presentamos una estrategia para acelerar la simulación y visualización de mezclado advectivo--difusivo de un contaminante dentro de una cavidad cuadrada con condiciones de frontera dependientes del tiempo. No se requieren paredes móviles para mezclar el fluido sino la convección natural…

Software tools processing partially common set of data should share an understanding of what these data mean. Since ontologies have been used to express formally a shared understanding of information, we argue that they can be used to improve integration…

We can make very sensitive machines and may arrange for them to distinguish themselves from other objects. The programs that are designed toward specific goals, such as the identification of external objects, can also be imagined as action programs relating…

This document describes a research and development project - Semantic Web and Cooperative Problem Solving for Online Communities of Practice. The aim of the project is to build a system supporting Cooperative Problem Solving within the framework of online Communities…

The term “Federated Databases” refers to the data integration of distributed, autonomous and heterogeneous databases. However, a federation can also include information systems, not only databases. When integrating data, several issues must be addressed. Here, we focus on the problem…

Product-line architectures, i.e. a software architecture and component set shared by a family of products, represents a promising approach to achieving reuse of software. Several companies are initiating or have recently adopted a product-line architecture. However, little experience is available…

Using COTS software promises faster time-to-market, which can yield substantial advantages over competitors with regards to earlier placement of a new product on a market. At the same time, component-based software introduces risks, such as unknown quality properties of the…

During the last years a lot of projects and lines of research have emerged from different proposals trying to find the best way to reach data integration. Two powerful techniques have appeared separately – ontology and contextual information – in…
