BCS: A Binary Cuckoo Search algorithm for feature selection
(2013-09-09)
Feature selection has been actively pursued in the last years, since to find the most discriminative set of features can enhance the recognition rates and also to make feature extraction faster. In this paper, the propose ...
Electrical consumers data clustering through optimum-path forest
(2011-12-21)
Non-technical losses identification has been paramount in the last decade. Since we have datasets with hundreds of legal and illegal profiles, one may have a method to group data into subprofiles in order to minimize the ...

(Universidade Tecnológica Federal do ParanáCuritibaBrasilCurso de Especialização em Energias RenováveisUTFPR, 2015-12-08)
This study proposes to verify the compliment to the requirements from a low cost Grid Tie inverter, usually found in international e-commerce web sites to connect to the power grid. With the growing of the photovoltaic ...
Análise das condições regulatórias e tecnológicas para a implantação do sistema pré-pago de tarifação e faturamento de energia elétrica no Brasil
(Universidade Tecnológica Federal do ParanáPato BrancoBrasilDepartamento Acadêmico de ElétricaEngenharia ElétricaUTFPR, 2016-11-11)
An innovative way to use and put price on electricity efficiently, but little known in Brazil, is through of prepaid charging system. In this new modality, the consumer must make the purchase of electricity credits, in the ...
Geração distribuída de energia elétrica a partir da biomassa no Paraná: entraves para a conexão à rede de distribuição
(Universidade Tecnológica Federal do ParanáCuritibaBrasilCurso de Especialização em Energias RenováveisUTFPR, 2016-10-05)
Brazil's commitments to sustainable policies, recently signed at the Convention on Climate Change in Paris in 2015, drive the country's energy transition: from fossil to cleaner energy sources, such as biomass. Particularly ...
