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...

Sistema de Vigilância para Detecção de Interações Espaço-tempo de Eventos Pontuais

The System of Surveillance proposed consists of the monitoring of a group of point events, in order to detecting quickly the formation of space-time clustering, as soon as begin to appear. It bases on the analysis of prospective statistical methods (on-line studies). In this article, it is to adapt the technique presented by Rogerson (2001), with the intention of detecting the existent cluster,...

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...
