This article proposes a model of a context-aware system, called DeCom, to support competence management. The model considers the profiles of employees in organizations and the contexts in which they are involved, looking for opportunities to help them to develop their competences. DeCom proposes a Context Model organized into five categories, which enable the mapping [...]
The evolution of computing technology and wireless networks has contributed to the miniaturization of mobile devices and their increase in power, providing services anywhere and anytime. In this scenario, applications have considered the user’s contexts to make decisions (Context Awareness). Context-aware applications have enabled new opportunities in different areas, for example, education, games and entertainment, [...]
Os profissionais estão constantemente em busca de qualificação e consequentemente tendo um acréscimo de conhecimento na sua área de atuação. Sendo assim, torna-se interessante o desenvolvimento de um sistema computacional que conheça o seu usuário e seu histórico de trabalho e permita que atividades previamente autorizadas para o uso, possam ser permitidas novamente em caso [...]
Social networks provide a growing mean of communication that still preserves our human social interaction. Due to the widespread use of mobile devices, and the vast development of applications targeting these platforms, people tend to use their smartphone or tablet as the main way to make that interaction. Furthermore, applications developed to these devices are [...]

The use of mobile and ubiquitous computing has been stimulated by the widespread diffusion of mobile devices, wireless networks and location systems. In this context, numerous applications are emerging in different areas such as education, entertainment, commerce and transport. This paper proposes the MD-UTS, a model for development of ubiquitous transport systems. The model allows [...]
The ubiquitous computing, or ubicomp, is a promising technology to help chronic diseases patients managing activities, offering support to them anytime, anywhere. Hence, ubicomp can aid community and health organizations to continuously communicate with patients and to offer useful resources for their self-management activities. Communication is prioritized in works of ubiquitous health for noncommunicable diseases [...]
This article proposes an infrastructure called Global. The main hypothesis consists in the possible creation of an architecture completely decentralized and extensible, focused in the development of ubiquitous learning environments. The text describes the infrastructure´s architecture. Additionally, the article presents an implementation and a concepts proof through the use of Global in the developing of [...]
The application of ubiquitous technologies in the improvement of education strategies is called Ubiquitous Learning. This article proposes the integration between two models dedicated to support ubiquitous learning environments, called Global and CoolEdu. CoolEdu is a generic collaboration model for decentralized environments. Global is an infrastructure designed to create ubiquitous learning environments. Global provides software [...]
