Process mining aims at discovering new knowledge based on information hidden in event logs. Two important enablers for such analysis are powerful process mining techniques and the omnipresence of event logs in today's information systems. Most information systems supporting (structured) business processes (e.g. ERP, CRM, and workflow systems) record events(More)
PURPOSE To evaluate the prevalence of tobacco smoking among health workers, professores, nurses and students of Federal University of São Paulo and the acceptance of an institutional program for quitting smoking. METHODS We analized the answers of a questionnairy with 51 questions, distributed to people from different categories. RESULTS The total(More)
Although smartphones include a set of sensors that enable innovative interactions, current mobile game interaction is mostly touch-based. Some games also include tilt movement based on the accelerometer sensor. However, sensors like accelerometers and gyroscopes can be used to recognize, in real time, full body motions. Exploring this can lead to innovative(More)
Stroke rehabilitation is far from meeting patient needs in terms of timing, intensity and quality. This study evaluates the efficacy and safety of an innovative technological tool, combining 3D motion analysis with targeted vibratory feedback, on upper-limb task performance early poststroke (<4 weeks). The study design was a two-sequence, two-period,(More)
Automatic keyword extraction (AKE) from textual sources took a valuable step towards harnessing the problem of efficient scanning of large document collections. Particularly in the context of urban mobility, where the most relevant events in the city are advertised on-line, it becomes difficult to know exactly what is happening in a place. In this paper we(More)
Our route choices depend on our own mental map of the city. This assumption, brought from the areas of spatial cognition and cognitive mapping, establishes a distorted graph as the cognitive model that represents our trips. The task of trajectory prediction consists of determining, when a driver is making a trip, which path will be chosen. Our approach(More)
This document details the design and development of Umbra, an installation-based game that makes use of a semi-transparent screen projected upon from both sides. The setup enables players to be represented in-game via their shadows, instead of avatars. This document discusses the design of Umbra and how its shadow-as-avatar mechanics advance the gaming(More)
