Failure analysis of quasi-brittle media using the micropolar continuum theory, elastic-degrading constitutive models, and smoothed point interpolation methods
(Universidade Federal de Minas GeraisUFMG, 2018-06-15)
The present thesis address the issue of localization (or discontinuous failure) in quasi-brittle materials modelled as elastic-degrading media, using two dierent regularization strategies, applied individually as well as ...
Acoplamento SPIM-FEM adaptativo para modelos de degradação elástica
(Universidade Federal de Minas GeraisBrasilENG - DEPARTAMENTO DE ENGENHARIA ESTRUTURASPrograma de Pós-Graduação em Engenharia de EstruturasUFMG, 2022-09-28)
This thesis proposes a new approach to performing a physically nonlinear analysis of structures constituted by quasi-brittle material employing a coupling between the smoothed point interpolation method (SPIM) and the ...
SRTM resample with short distance-low nugget kriging
(TAYLOR & FRANCIS LTD, 2008)
The shuttle radar topography mission (SRTM), was flow on the space shuttle Endeavour in February 2000, with the objective of acquiring a digital elevation model of all land between 60 degrees north latitude and 56 degrees ...

Filtragem de nuvem laser para geração de MDT por krigagem
(2017-01-01)
This paper presents a method of filtering point clouds generated by laser scanning, to obtain a Digital Terrain Model (DTM). The filtering process is performed based on an approximated surface obtained from urban road ...
An algorithm for generation of DEMs from contour lines considering geomorphic features
(Universidad Nacional de Colombia - Sede Bogotá - Facultad de Ciencias - Departamento de Geociencia, 2016-04-01)
Geomorphic information is omitted from many existing methods of generating gridded digital elevation models (DEMs) from contour lines, resulting in significant errors during interpolation. Here, we present an advanced ...
Mapeamento aproximado da resistividade em subsuperfície usando dados de resistividade aparente e geoestatística
(BrasilUFRNPROGRAMA DE PÓS-GRADUAÇÃO EM GEODINÂMICA E GEOFÍSICA, 2015-04-16)
It is presented a new method for the approximate mapping of the subsurface resistivity based
on a geostatistical approach. It are used the characteristic points (CPs) of a resistivity sounding,
which are their inflection ...
