(Investigacion En Educacion Matematica Xiii, 2009-01-01) [Trabalho apresentado em evento]
Study of the ℤ3 symmetry in QCD at finite temperature and chemical potential using a worm algorithm
(AIP Conference Proceedings, 2013-04-24) [Trabalho apresentado em evento]
Traditional Monte Carlo simulations of QCD in the presence of a baryon chemical potential are plagued by the complex phase problem and new numerical approaches are necessary for studying the phase diagram of the theory. ...
A multisensor, multitemporal approach for monitoring herbaceous vegetation growth in the Amazon floodplain
(Multitemp 2013: 7th International Workshop On The Analysis Of Multi-temporal Remote Sensing Images, 2013-01-01) [Trabalho apresentado em evento]
The Amazon River floodplain is an important source of atmospheric CO2 and CH4. Aquatic herbaceous vegetation (macrophytes) have been shown to contribute significantly to floodplain net primary productivity (NPP) and methane ...
Image segmentation through combined methods: watershed transform, unsupervised distance learning and normalized cut
(2014 Ieee Southwest Symposium On Image Analysis And Interpretation (ssiai 2014), 2014-01-01) [Trabalho apresentado em evento]
Research on image processing has shown that combining segmentation methods may lead to a solid approach to extract semantic information from different sort of images. Within this context, the Normalized Cut (NCut) is usually ...

(2014 27th Sibgrapi Conference On Graphics, Patterns And Images (sibgrapi), 2014-01-01) [Trabalho apresentado em evento]
Relevance feedback approaches have been established as an important tool for interactive search, enabling users to express their needs. However, in view of the growth of multimedia collections available, the user efforts ...
Wordnet.Br: An Exercise of Human Language Technology Research
(Gwc 2006: Third International Wordnet Conference, Proceedings, 2005-01-01) [Trabalho apresentado em evento]
This paper reports the ongoing project (since 2002) of developing a wordnet for Brazilian Portuguese (Wordnet.Br) from scratch. In particular, it describes the process of constructing the Wordnet.Br core database, which ...
Labeling methods for association rule clustering
(ICEIS 2012 - Proceedings of the 14th International Conference on Enterprise Information Systems, 2012-09-10) [Trabalho apresentado em evento]
Although association mining has been highlighted in the last years, the huge number of rules that are generated hamper its use. To overcome this problem, many post-processing approaches were suggested, such as clustering, ...
An investigations on local and global behavior of a (SMA) oscillator of 3 - DOF driven by a limited power supply
(Proceedings of the ASME International Design Engineering Technical Conferences and Computers and Information in Engineering Conference 2009, DETC2009, 2010-06-25) [Trabalho apresentado em evento]
SMART material systems offer great possibilities in terms of providing novel and economical solutions to engineering problems. The technological advantages of these materials over traditional ones are due to their unique ...
Automatic segmentation of digital images applied in cardiac medical images
(Pan American Health Care Exchanges, PAHCE 2010, 2010-07-09) [Trabalho apresentado em evento]
The digital image processing has been applied in several areas, especially where it is necessary use tools for feature extraction and to get patterns of the studied images. In an initial stage, the segmentation is used to ...
