Quantitative decision-making relies on appropriate mathematical models of the systems about which decisions are to be made. Intelligent transport systems (ITS), which apply combined advanced detection, communication, and computer science technologies to traffic and transport systems, are im-portant examples of such quantitative decision support systems.(More)
The corneal maps displayed on commercially available corneal topography instruments are really one-dimensional, defining quantities only along a meridian, and ignoring shape information along any other direction. Both axial and instantaneous power have the drawbacks that there is a singularity at the center data point on the videokeratograph axis, and the(More)
Several methods for representing pupil plane aberrations based on wavefront height, slope, and curvature are discussed. The choice of reference axis and reference surface is shown to strongly affect the appearance of the representation. Special attention will be paid to the use of the line of sight (the line from the fixation point to the center of the(More)
Key issues/challenges/questions effecting IB and its adoption: • How will IB play with other IO interconnect and networking technologies (pcix, pci2.0, pciexpress, ethernet, fibre channel) • What role will IB play in future data centers. • What are IBs strengths and weaknesses compared to other interconnect technologies. • Why is the IB architecture so(More)
The present paper describes a new color image segmentation algorithm which it has been applied with notable sucsess in the supervised automation of the inoculation process of the microbian cultures. The method is based on the 3D histogram thresholding to divide the image which is converted into three-dimensional L*a*b* color space in two diferenciated(More)
We present an approach to recognize 3D objects from the information available in one image. To get it we develop a method based in a two step algorithm. In the first step, each 3D model will be converted in a set of 2D images using an aspect graph algorithm in which the concept of visual event it is defined as the moment when the projective invariants got(More)
This article presents the idea of the PrepNet.Br, a semantic network consisting of synsets of prepositions to be built for Brazilian Portuguese along the lines of the French PrepNet [Saint-Dizier 2005]. This enterprise is of relevance to the linguistic description of the class of prepositions as well as to Natural Language Processing resource-building. The(More)
