Descrição: A time series is a series of data points indexed (or listed or graphed) in time order. Most commonly, a time series is a sequence taken at successive equally spaced points in time. Thus it is a sequence of discrete-time data.Time series analysis comprises methods for analyzing time series data in order to extract [...]
Anesthesia Information Management Systems (AIMSs) have existed for many decades. However, how to turn patient records into strategic information to improve the anesthesia process is still a research challenge. We did not find systems that use data from previous procedures for issuing alerts. This data can prevent errors during procedures and aid on medical staff [...]
Context The integration of feature models has been widely investigated in the last decades, given its pivotal role for supporting the evolution of software product lines. Unfortunately, academia and industry have overlooked the production of a thematic analysis of the current literature. Hence, a thorough understanding of the state-of-the-art works remains still limited. Objective This [...]
Neste artigo é proposto Ebenezer, um modelo de computação ubíqua para prevenir acidentes em um ambiente de trabalho inteligente. Sua principal característica é a notificação aos trabalhadores e aos usuários em geral sobre a presença de perigos nos arredores, para evitar riscos de acidentes. A aplicação e validação foram realizadas com os trabalhadores em [...]
The amount of data generated by computer systems in Online Distance Learning (ODL) contains rich information. One example of this information we define as the Learner Learning Trail (LLT), which is the sequence of interactions between the students and the virtual environment. Another example is the Learner Learning Style (LLS), which is associated with the [...]
This article proposes a computational system to assist wheelchair users, improving accessibility through ubiquitous computing technologies. TrailCare uses indoor and outdoor location information to assist wheelchair users, recording their trails and providing context-aware assistance. Trails are historical records of users’ displacements that can be used to develop strategic accessibility solutions, such as security management and [...]
This article proposes an integrated system for management of waiting times in hospital emergencies, called SIGTE. The system minimizes the waiting time of patients in the hospital emergency queues of the Sistema Único de Saúde (SUS), balancing the demands of care and mitigating problems of overcrowding. The SUS guarantees the population free access to health [...]
Depression is a common mental disorder that causes sadness and loss of interest. It affects 350 million people in the world and its most severe state can lead to suicide. Many technologies are being used to aid the depression treatment and gamification has been used as an approach to improve adherence and engagement in the [...]
