PerCare: Um Modelo Computacional para Cuidados Ubíquos orientados à Acessibilidade

Descrição: O projeto propõe um modelo computacional para cuidados ubíquos orientados à acessibilidade, denominado PerCare (Personal Care). Nesse sentido, o projeto aplica a Computação Ubíqua no suporte à acessibilidade (Acessibilidade Ubíqua para Pessoas com Deficiência (PCDs) e idosos. A principal inovação da proposta consiste na amplitude do modelo, o qual suportará de forma integrada e [...]

A Model for Ubiquitous Transport Systems Support

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 [...]

A Model for Ubiquitous Care of Noncommunicable Diseases

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 [...]

A Decentralized Infrastructure for Ubiquitous Learning Environments

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 [...]

A Middleware Architecture for Dynamic Adaptation in Ubiquitous Computing

The development of applications that adapt to the environment and remain running even when the user is moving or switching device, remains an open research challenge. In this article we present a view of the EXEHDA middleware and a new service created for dynamic adaptation. EXEHDA is service-oriented, adaptive and was conceived to support the [...]

Spectral Model for Soybean Yield Estimate Using MOD-IS/EVI Data

Attaining reliable and timely agricultural estimates is very important everywhere, and in Brazil, due to its characteristics, this is especially true. In this study, estimations of crop production were made based on the temporal profiles of the Enhanced Vegetation Index (EVI) obtained from Moderate Resolution Imaging Spectroradiometer (MODIS) images. The objective was to evaluate the [...]

GPU-based approaches for real-time sound source localization using the SRP-PHAT algorithm

In most microphone array applications, it is necessary to localize sound sources in a noisy and reverberant environment. For that purpose, many different Sound Source Localization (SSL) algorithms have been proposed, where the SRP-PHAT (Steered Response Power using the Phase Transform) has been known as one of the state-of-the-art methods. Its original formulation allows two [...]

A proposal of an infrastructure for load-balancing transactions on electronic funds transfer systems

This article aims to present the first ideas for developing a framework for load-balancing called GetLB. Considering the electronic funds transfer (EFT) context, GetLB offers a new scheduling heuristic that optimizes the selection of Processing Machines to execute transactions in a processing center. Instead of using the Round-Robin typical approach, the proposal combines data from [...]

Utilização de processamento de linguagem natural e ontologias na análise qualitativa de frases curtas

O volume de dados digitais disponíveis é cada vez maior em todos os segmentos profissionais e essa realidade não é diferente no campo educacional, principalmente quando falamos sobre Educação a Distância e ambientes virtuais de aprendizagem. Um dos desafios neste cenário é o tratamento de dados em linguagem natural, de forma com que existam ganhos [...]

Elasticidade em cloud computing: conceito, estado da arte e novos desafios

A elasticidade é, sem dúvida, uma das características mais marcantes da computação em nuvem, sendo um diferencial desse tipo de sistema distribuído em relação a outros, como grades computacionais e peer-to-peer. Com base nos paradigmas de computação sobre demanda e pague-pelo-que-use, é possível dinamicamente aumentar ou diminuir instâncias de máquinas virtuais e/ou nós de computação, [...]
