One of many possibilities is patient monitoring through wearable devices and mobile
applications. In ord...
Abordagens, como a gamificação, surgem com a proposta de melhorar a motivação dos alunos, trazendo elementos de jogos para a escola. No entanto, empregar gamificação na sala de aula não é uma tarefa trivial, pois, se não for gerenciado adequadamente, os alunos podem perder o foco. Neste artigo apresentamos um relato de experiência usando GAMED, uma...
In the educational field, there is a concern about helping children to develop emergent literacy skills such as reading and writing. However, this is not a trivial task since children may have different needs based on their skill levels. In this sense, we present an approach that employs mobile and cloud computing technology to adapt activities fro...
The integration of disciplines in higher technology courses is a significant challenge. Sometimes the student can not visualize the correlations between different knowledge in the direction of a complete formation. This paper shows an integrated professional practice that relies on an innovation discipline to discover and prospect new technological...
Teachers and psychologists report that students may suffer from multiple psychological issues such as lack of interest and high levels of stress during the development of final course projects. In this context, approaches such as gamification arise with the proposal of improving students motivation by bringing games elements to school. However, emp...
Computational grids consist of distributed environments where partner institutions offer hosts along with computational resources that can be used by all members of the grid. When an application needs to run in such environment, it allocates a portion of hosts necessary for its executions. Traditionally, the workload imposed on computational grids...
The popularity of mobile devices has increased significantly, and nowadays they are used for the most diverse purposes like accessing the Internet or helping on business matters. Such popularity emerged as a consequence of the compatibility of these devices with a large variety of applications. However, the complexity of these applications boosted...
The cloud native approach is getting more and more popular with the proposal of decomposing application into small components called microservices, which are designed to minimize the costs with upgrades and maintenance and increase the resources usage efficiency. However, microservices architecture brings some challenges such as preserving the mana...
In the last decade we noticed a growth on studies regarding energy savings in data centers.
