The development of graphical user interfaces (GUIs) has been an emergent demand in the area of healthcare technologies. Specifically for respiratory healthcare there is a lack of tools to produce a complete multimedia database, where respiratory sounds and other clinical data are available in a single repository. This is essential for a complete patient's(More)
This paper describes the implementation of INFIBRA, a machine vision system used in the quality control of acrylic fibre production. The system was developed by INETI under a contract with a leading industrial manufacturer of acrylic fibres. It monitors several parameters of the acrylic production process. This paper presents, after a brief overview of the(More)
OBJECTIVES The development of effective graphical user interfaces (GUIs) has been in an emergent demand in healthcare technologies, for assessing, managing and storing patients' clinical data. Nevertheless, specifically for respiratory care there is a lack of tools to produce a multimedia database, where the main respiratory clinical data can be available(More)
—We introduce the first sweep line algorithm for computing spherical Voronoi diagrams, which proves that Fortune's method can be extended to points on a sphere surface. This algorithm is similar to Fortune's plane sweep algorithm, sweeping the sphere with a circular line instead of a straight one. Like its planar counterpart, the novel linear-space(More)
