Workflow has become a standard for many scientific applications that are characterized by a collection of processing elements and an arbitrary communication among them. In particular, a pipeline application is a type of workflow that receives a set of tasks, which must pass through all processing elements (also named here as stages) in a linear [...]
One of the most recently proposed 5G architectures, Fog Radio Access Network or F-RAN, has the same cloud computing-based approach of C-RANs while giving additional storage and processing power to the edge nodes so that they can address network activities. The main problem of F-RANs is the intense data traffic in the fronthaul, which is [...]
Bed management is an important area of planning and control for hospitals, as it has the important role of maintaining the balance between patients from the emergency department, patients who have elective surgery or scheduled treatment, and patients who are discharged from the hospital, while maintaining high bed occupancy rates. Effective management of these resources [...]
Redes Sociais Educacionais (RSE) podem proporcionar espaços de interação e trocas entre aprendizes, mas não garantem motivação para que estas aconteçam. O INTERACT se utiliza do histórico contextual dos usuários para potencializar interações entre usuários de RSE. Além do modelo, é apresentado o protótipo desenvolvido. A avaliação se deu com coleta de dados gerados pelas [...]
Health information technology, applied to electronic health record (EHR), has evolved with the adoption of standards for defining patient health records. However, there are many standards for defining such data, hindering communication between different healthcare providers. Even with adopted standards, patients often need to repeatedly provide their health information when they are taken care of [...]
Imagens médicas são usadas diariamente para apoio ao diagnóstico em diferentes áreas da Radiologia no mundo todo. No entanto, há uma grande necessidade de que essas imagens sejam analisadas por diferentes especialistas e discutidas de forma ampla na busca do melhor tratamento para cada patologia. Em ambientes clínicos transmitir essas imagens em tempo hábil é [...]
Camera setups with multiple devices are a key aspect of ambient monitoring applications. These types of setups can result in data corruption when applied to recent RGB-D camera models because of mutual interference of the infrared light emitters employed by such devices. Consequently, the behavior of such interference must be appropriately evaluated to provide data [...]
Today cloud elasticity can bring benefits to parallel applications, besides the traditional targets including Web and critical-business demands. This consists in adapting the number of resources and processes at runtime, so users do not need to worry about the best choice for them beforehand. To accomplish this, the most common approaches use threshold-based reactive elasticity [...]
Recent efforts regarding mobile social networks aim at connecting people in smart environments considering not only their social behavior but also their context. In this perspective, this work presents a model, named SSN, based on the concept of Spontaneous Social Network, which allows the interaction of people anywhere and anytime without the need of any [...]
Activities of a clinical staff in healthcare environments must regularly be adapted to new treatment methods, medications, and technologies. This constant evolution requires the monitoring of the workflow, or the sequence of actions from actors involved in a procedure, to ensure quality of medical services. In this context, recent advances in sensing technologies, including Real-time [...]
