Comparison of linear measurements and analyses taken from plaster models and three-dimensional images
Digital models are an alternative for carrying out analyses and devising treatment plans in orthodontics. The objective of this study was to evaluate the accuracy and the reproducibility of measurements of tooth sizes, ...
Semi-automatic modeling of buildings from digital surface models
Semi-automatic building detection and extraction is a topic of growing interest due to its potential application in such areas as cadastral information systems, cartographic revision, and GIS. One of the existing strategies ...

Digital filtering of oscillations intrinsic to transmission line modeling based on lumped parameters
A correction procedure based on digital signal processing theory is proposed to smooth the numeric oscillations in electromagnetic transient simulation results from transmission line modeling based on an equivalent ...
DIGITAL ELEVATION MODEL VALIDATION WITH NO GROUND CONTROL: APPLICATION TO THE TOPODATA DEM IN BRAZIL
(Univ Federal Parana, Centro Politecnico, 2014-04-01)
Digital Elevation Model (DEM) validation is often carried out by comparing the data with a set of ground control points. However, the quality of a DEM can also be considered in terms of shape realism. Beyond visual analysis, ...
Segmentação de dados de perfilamento a laser em áreas urbanas utilizando uma abordagem Bayesiana
In this paper is presented a region-based methodology for Digital Elevation Model segmentation obtained from laser scanning data. The methodology is based on two sequential techniques, i.e., a recursive splitting technique ...
Simplified computational routine to correct the modal decoupling in transmission lines and power systems modelling
Modal analysis is widely approached in the classic theory of power systems modelling. This technique is also applied to model multiconductor transmission lines and their self and mutual electrical parameters. However, this ...
