1. Minimization of polymerization shrinkage effects on composite resins by the control of irradiance during the photoactivation process
Abstract High levels of shrinkage stress caused by volumetric variations during the activation process are one of the main problems in the practical application of composite resins. Objective The aim of this study is to reduce the shrinkage stress and minimize the effects caused by composite resin volumetric variation due to the photopolymerization. In thi

2. Detection of movement intention using EEG in a human-robot interaction environment
Introduction : This paper presents a detection method for upper limb movement intention as part of a brain-machine interface using EEG signals, whose final goal is to assist disabled or vulnerable people with activities of daily living. Methods EEG signals were recorded from six naïve healthy volunteers while performing a motor task. Every volunteer remain

3. Cognitive Based Design of a Human Machine Interface for Telenavigation of a Space Rover
ABSTRACT: Human Machine Interface (HMI) design is a critical field of work because no general guidelines or rules have been assessed. In order to aid practitioners to design effective HMIs, different methodologies have been studied. To understand task objectives and plan goal-oriented actions, human operators exploit specific cognitive processes that have to

4. Impact of light-curing time and aging on dentin bond strength of methacrylate- and silorane-based restorative systems
AIM: To evaluate the impact of different light-curing times on dentin microtensile bond strength of two restorative systems after 24 h and 6 months of water storage. METHODS: Standardized Class II preparations were performed in 56 freshly-extracted human molars (n = 7), restored with methacrylate- or silorane-based restorative systems, and light-cured

5. Rebonding of unused brackets with different orthodontic adhesives
OBJECTIVE: To compare in vitro shear bond strength (SBS) of different orthodontic adhesives in bonding and repeatedly rebonding metal brackets, and to evaluate the bond failure site with the adhesive remnant index (ARI). METHODS: Specimens consisted of 90 extracted human first premolars, randomly divided into three groups (n=30). The adhesives Alpha Plast (A

6. Efeito da base de cimento de ionômero de vidro modificado por resina e técnicas de inserção de resina composta na interface dentina/restauração adesiva / Effect of resin-modified-glass-ionomer linning and composite placement on adhesive interface
The aim of this study was to evaluate the effect of resin-modified-glassionomer linning and incremental technique on the bond strength of the composite restoration interface. Methods: Cavities were made (4.5mm X 3mm X 5mm) in 52 extracted human molars, divided into 4 groups: Group 1 (control) no linning + two horizontal increments (C Factor = 5); Group 2: no

7. Object tracking from compressed video using Kalman Filter and a novel spatiotemporal motion-vector filter.
Video Object Tracking plays a crucial role on several Computer Vision applications, such as Video Surveillance, Intelligent Transportation System (ITS), Human Machine Interface (HMI), Video Indexing and Shopping Behavior Analysis. Nevertheless, the processing power demanded by object tracking techniques still consists in a bottleneck to their wider adoption.

8. Desenvolvimento de Uma Órtese Ativa Para os Membros Inferiores Com Sistema Eletrônico Embarcado
This work presents the development of a prototype of an intelligent active orthosis for lower limbs whit an electronic embedded system. The proposed orthosis is an orthopedical device with the main objective of providing walking capacity to people with partial or total loss of lower limbs movements. In order to design the kinematics, dynamics and the mechani

10. Uma proposta de interface de consulta para recuperação de informação em documentos semi-estruturados
A Recuperação Semi-Estruturada é uma forma de recuperação de informação intermediária entre a Recuperação Textual e a Recuperação Estruturada (típica em sistemas de banco de dados relacionais). Em sistemas de recuperação estruturada, o usuário geralmente conhece a estrutura dos dados e as linguagens de consulta disponíveis, conseguindo assim

11. Application of human machine interface research in powered wheelchair / Aplicação do estudo da interface homem maquina em cadeiras de rodas motorizadas
Há uma parcela da população que, por possuir severas limitações físicas e motoras, é inapta a utilizar cadeiras de rodas convencionais, manuais ou elétricas, bem como dispositivos de interface que não consideram as suas características particulares. Deste modo, este trabalho possui foco no desenvolvimento de interfaces e sistemas de navegação par
