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 [...]
The photogrammetry techniques are known to be accessible due to its low cost, while the geometric accuracy is a key point to ensure that models obtained from photogrammetry are a feasible solution. This work evaluated the discrepancies in 3D (DSM) and 2D (orthomosaic) models obtained from photogrammetry using control points (GCPs) near a reflective/refractive area [...]
The goal of this paper is to present a new relationship between the quality criteria for geodetic networks. The quality criteria described here are fourfold: positional uncertainty of network points, considering both bias and precision (at a given confidence level); the maximum allowable number of undetected outliers; the level of reliability and its homogeneity for [...]
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 [...]
Na Geodésia, o controle de qualidade (CQ) é uma das etapas de maior importância, onde é decidido se os resultados obtidos serão validados ou não. Dentro desse contexto, os testes estatísticos ainda são as ferramentas mais utilizadas para detecção e identificação de outliers (erros não aleatórios), dentre eles o famoso Data Snooping proposto por Baarda. [...]
