Construções euclidianas e o desfecho de problemas famosos da geometria
(2011)
Construction techniques with ruler and the compasses, fundamental on Euclidean geometry, have been related to modern algebraic theories such as solving equations and extension of bodies from the works by Paolo Ruffini ...
Development and applications of three-dimensional gamma ray tomography system using ray casting volume rendering techniques
(Sociedade Brasileira de Física, 2005-09-01)
Computed Tomography (CT) has made possible visualization of physical structures in the interior of an object in their real relative spatial position and orientation. Another important contribution of CT is to greatly improve ...
Refracciones y reflexiones simultáneas en estimación de velocidades mediante tomografía basada en rayos.
(Fondo Editorial EIA - Universidad EIA, 2020-02-03)
En este trabajo se presenta una estrategia de trazado de rayos con aplicación a los problemas de tomografía sísmica. El trazador está basado en el método del camino más corto. La estrategia permite calcular trayectorias ...

A versatile laboratory platform for studying x-ray 3D breast imaging
(IEEE, 2011)
Purpose: This paper presents the features of a new laboratory x-ray platform for 3D breast imaging at FDA and initial projection images and tomosynthesis reconstructions. Materials and methods: The laboratory consists of ...
Numerical simulations to assess ART and MART performance for ionospheric tomography of chapman profiles
(2017-07-01)
The incomplete geometrical coverage of the Global Navigation Satellite System (GNSS) makes the ionospheric tomographic system an ill-conditioned problem for ionospheric imaging. In order to detect the principal limitations ...
