8. 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

11. Segmentação das áreas isquêmicas no acidente vascular cerebral utilizando imagens de tomografia computadorizada de perfusão / Segmentation of ischemic areas in stroke using perfusion computed tomography images
The techniques of digital image processing have been widely applied to medical imaging. One of the benefits brought about by these tools is to provide measurements of parameters that are difficult to estimate and likely to bias the physician. This study aimed to develop semi-automatic software of segmentation of the ischemic areas, core and penumbra in strok
