Many researchers have pursued the establishment of a low-cost, effective testing and validation strategy at the program level as well as at the specification level. Mutation Testing is an error-based approach, originally introduced for program testing, that provides testers a systematic way to evaluate how good a given test set is. Some studies have also(More)
Ubiquitous Learning (UbiLearning) environments heavily employ mobile devices to empower users with mobility and tooling support to learn anytime, anywhere. Introducing mobile devices in educational settings imposes constraints on search behavior due to limited resources on these devices such as small screens and restricted input functionalities. Targeting(More)
This paper proposes a Ubiquitous Computing Environment for Medical Education, whose kernel is a Web-based system with collaborative tools, to support the interactions and computational tasks among different actors involved in the Medical Education process. In order to allow this environment to be ubiquitous, the Web pages of this system are adapted, through(More)
— In Pervasive Healthcare, novel information and communication technologies are applied to support the provision of health services anywhere, at anytime, and to anyone. Ubiquitous Computing technologies allow efficient and safe information exchange amongst caregivers and their patients in communities, homes and hospitals. Since health systems may offer(More)
This paper proposes an information retrieval process that employs a relevance feedback approach based on implicit evidences provided by contextual information and explicit evidences provided by the user behavior during interaction. This process takes advantage of semantic information processing enabled by the use of ontologies to build semantic indexes, to(More)
This paper presents an approach that combines Ontologies, Semantic Web Services and Mobile Agents, for the Component-Based Software Development. The Ontologies are employed to improve the problem domain analysis, and to get software components with a semantic description, which may be reused in a wide variety of applications. The Semantic Web Services are(More)
