Previous issue date: 2005-07-26 / Conselho Nacional de Desenvolvimento Científico e Tecnológico / Coryphoridae, Leptohyphidae e Melanemerellidae constituem a superfamília Ephemerelloidea (Insecta: Ephemeroptera) na América do Sul. No Brasil, apesar de todas estas famílias estarem representadas, o número de espécies conhecidas ainda é reduzido. Visando contribuir para o conhecimento dos Ephemerelloidea na Região Sudeste do Brasil, foram estudados espécimes provenientes dos estados do Espírito Santo, Minas Gerais, Rio de Janeiro e São Paulo. A partir destes estudos está sendo proposta uma chave de identificação para ninfas e adultos de todos os gêneros e espécies de Ephemerelloidea conhecidos para o Brasil. Quatro novas espécies de Leptohyphidae são descritas, três delas pertencentes ao gênero Tricorythopsis Traver e uma pertencente à Tricorythodes Ulmer. A espécie Tricorythodes santarita Traver é registrada pela primeira vez para o Brasil. A partir dos novos registros e das espécies novas descritas neste trabalho, a Região Sudeste do Brasil passa a representar 60 % do conhecimento total de Ephemerelloidea no país. / Coryphoridae, Leptohyphidae and Melanemerellidae constituted Ephemerelloidea (Insecta: Ephemeroptera) in the South America. In Brazil, despite of all these families are represented, the number of species known still is very limited. With the goal at contribute for the knowledge of the Ephemerelloidea in the Southeastern Region of Brazil, specimens of the Espirito Santo state, Minas Gerais state, Rio de Janeiro state and São Paulo state were studied. A key of identification for all genera and species of the families Coryphoridae, Leptohyphidae and Melanemerellidae based on nymphs and adults is proposed. Four new species they were described, three of Tricorythopsis Traver and one for Tricorythodes Ulmer. The specie Tricorythodes santarita Traver was recorded by the first time for Brazil. Because the new records and the new species described of this study, the knowledge of the Ephemerelloidea of the Brazil`s Southeastern Region comprises 60% of the total knowledge of the group in the country.

This thesis deals with the monitoring of wireless nets in terrain. The author will be browsing terrain and there will be extracted some information about accessible wireless nets. For parameters of wireless nets we consider for example the name of wireless net, signal strength, type of security etc. These parameters (of wireless nets and position) are going to be recorded and saved into the database. Using this database it will be possible to perform some further operations like generation maps of wireless networks or detection positions of access points, etc..
