Um relato para lembrar Darcy Ribeiro

The utopian Darcy Ribeiro archive.

The project in memory of anthropologist, writer and politician Darcy Ribeiro is analyzed, with emphasis on the relationship he had with his personal archives and the creation of the Darcy Ribeiro Foundation, established to give continuity to his 'legacy.' It highlights the influences present in the formation of his archive and presents an ethnography that seeks to restore the historicity of the...

Um modelo conceitual para ambientes virtuais flexíveis

Hierarquias de Conceitos para um Ambiente Virtual de Ensino Extraídas de um Corpus de Jornais Populares

In this paper we present conceptual hierarchies automatically obtained from the popular newspaper Diário Gaúcho. The hierarchies were generated by means of ExATOlp tool through the extraction of noun phrases considered concept candidates by applying linguistic and statistic approaches. When accessed in a virtual learning environment, the hierarchies became a differentiated resource for vocabula...

QEDS: Um Simulador Clássico para Distinção de Elementos Quântico

The problem of deciding whether all N elements in a list are distinct requires Ω(N) queries in the classical setting. A quantum algorithm based in quantum walk on a Johnson graph improves this bound to O(N) queries. The quantum algorithm for element distinctness performs several steps of calculations each involving nontrivial superpositions of states. For this reason, it is difficult to study t...
