A formalized optimum code search for q-ary trellis codes
(Institute of Electrical and Electronics Engineers (IEEE), 1997-01-01)
This paper gives a formalization for q-ary codes of the search algorithm [3] for optimum codes based on lattices and cosets [1]. With a more efficient and an automated algorithm it also has been possible to extend the ...
Application of Evolutionary Algorithms on Unsupervised Segmentation of Lymphoma Histological Images
(Ieee, 2017-01-01)
Histological images analysis is widely used to carry out diagnoses of different types of cancer. Digital image processing methods can be used for this purpose, leading to more objective diagnoses. Segmentation techniques ...
Multilevel refinement based on neighborhood similarity
(Association for Computing Machinery - ACMInstituto Superior de Engenharia do Porto - ISEPPorto, 2014-07)
The multilevel graph partitioning strategy aims to reduce the computational cost of the partitioning algorithm by applying it on a coarsened version of the original graph. This strategy is very useful when large-scale ...
Multi-relational algorithm for mining association rules in large databases
(2011-12-01)
Multi-relational data mining enables pattern mining from multiple tables. The existing multi-relational mining association rules algorithms are not able to process large volumes of data, because the amount of memory required ...
Motion-based wave inference: monitoring campaign on a turret EPSO
(ASMEBusan, South Korea, 2016-06-19)
In recent years, considerable effort has been made in order to validate different methods that aim at estimating the wave spectra from the motions recorded on a ship or on an offshore platform. For more than ten years now, ...
Modelling radiation and energy balances with Landsat 8 images under different thermohydrological conditions in the Brazilian semi-arid region
(Spie-int Soc Optical Engineering, 2015-01-01)
Four Landsat 8 images were used together with a net of seven agro-meteorological stations for modelling the large-scale radiation and energy balances in the mixed agro-ecosystems inside a semi-arid area composed by irrigated ...
Faster α-expansion via dynamic programming and image partitioning
(2020-07-01)
Image segmentation is the task of assigning a label to each image pixel. When the number of labels is greater than two (multi-label) the segmentation can be modelled as a multi-cut problem in graphs. In the general case, ...

A new Solution to perform Data Dissemination in Vehicular Networks
(Ieee, 2014-01-01)
Vehicular Ad Hoc Networks (VANET) provide safety, traffic efficiency and user comfort for drivers and passengers. To reach these goals many envisaged applications for VANETs will rely on data dissemination, turning this ...
