Data sharing and especially enabling third parties to build new services using large amounts of shared data is clearly a trend for the future and a main driver for innovation. However, sharing data is a challenging and involved process today:…

We present here the first visual interface for a Mexican Spanish Sign Language translator on its first development stage: sign-writing recognition. The software was developed for the unique characteristics of Mexican linguistics and was designed in order to use sentences…

The book deals with the topic of Operating Systems from and intuitive perspective and then delves into more technical concepts, which makes it appropriate for a first introductory course on the matter.

Globally optimal triangulations are difficult to be found by deterministic methods as, for most type of criteria, no polynomial algorithm is known. In this work, we consider the Minimum Weight Triangulation (MWT) problem of a given set of n points…

Metric-temporal databases are a new database model that combines metric spaces with temporal databases to process similarity queries within a time interval or snapshot. The Historical FHQT is a metric-temporal index which has shown to be competitive answering this type…

Component Based Software Development (CBSD) relies upon utilization of previously developed software components OTS (Off-The-Shelf), which are appropriately merged to satisfy particular system requirements. However, wide acceptance of this paradigm at industry requires efficient component identification and selection, aspects which…

The methodologies for agile software development are fundamentally based on the collaboration with software users during the entire development process, the simplicity to adapt the product to changes in requirements, and on the incremental product delivery. Based on the Agile…

The Semantic Web is a vision of the current Web where resources have exact meaning assigned in terms of ontologies, thus enabling agents to reason about them. As inconsistencies cannot be treated by standard reasoning approaches, we use Defeasible Logic…

Interaction between user and computer is gradually going beyond the traditional mouse and keyboard. New ways of interaction are emerging, which use new and different means for data acquisition. Virtual or augmented reality, haptic, tangible or camerabased user interfaces are…

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 Engineering that can be solved by using this approach.…
