О некоторых аспектах методологического значения доказательства

Ильичев, Николай (1997)
The article analyses epistemological, logical and other functions of the category of demonstration. It also reveals its role in the formation of a scientific view of the world and shows the correlation between demonstration and conviction.

Aplicação do processamento homomorfico na discriminação de massas e microcalcificações em monogramas digitais

Marco Antonio Garcia de Carvalho (1997)
Resumo: Este trabalho apresenta um método para identificação de massas e microcalcificações em mamogramas digitais baseado no Processamento Homomórfico. Esta técnica atua no enriquecimento das imagens mamográficas através de uma filtragem não-linear e é fundamentada no modelo multiplicativo de formação de imagens. O trabalho contribui com uma técnica viável de segmentar as lesões tipo massas e microcalcificações, importantes no diagnóstico de câncer de mama Abstract: This works presents a ...

As Distorções na Representação dos Estados na Câmara dos Deputados Brasileira

Nicolau, Jairo Marconi (1997)
The article investigates two dimensions of the disproportionate distribution of Lower House seats among Brazilian states: the federalist and the party dimensions. In the first case, states ¾ and, consequently, their citizens ¾ are deemed the main beneficiaries or losers. In the second case, parties are seen as under or over-represented as a result of the prevailing distribution. The federalist dimension is evaluated bases on data regarding twenty-six legislatures since 1881, taking into accou...

Lavteknologisk jernframstilling i Rogaland i jernalder og middelalder

Haavaldsen, Per (1997)
This paper deals with iron extraction sites from the Iron Age and the Medieval period in Rogaland county, Norway. In Southwestern Norway prehistoric and medieval traces of iron production from bog ore have been rather neglected until some 10 years ago. From Rogaland county this paper records 45 iron extraction sites from the Iron Age and the Medieval period and 33 localities with charcoal pits which probably connect with iron production in the Late Iron Age and the Middle Ages. Fi...

Anatomía de una metropoli discontinua : la Barcelona metropolitana

Font Arellano, Antonio (1997)
La majoria de grans metròpolis contemporànies coneixen avui processos de difusió de les seves estructures urbanes sobre el territori. Aquests processos donen lloc a diverses tipologies de creixement que, en el cas de la metròpoli barcelonina, presenten una notable especificitat. En efecte, la presència d’una potent estructura territorial prèvia ha conferit al desenvolupament metropolità barceloní importants peculiaritats. Així, Barcelona ha esdevingut una metròpoli discontínua en la qual, jun...

Los catálogos colectivos y en sala como instrumentos en la selección de fuentes y canales de información

Cañedo Andalia, Rubén (1997)
The collective catalogues constitute reference instruments of topographic character that they make possible, from the systematic registry of the acquisition of the sources and information channels, to share resources two or more organizations of information

Development of a population-specific regression equation to estimate total body water in hemodialysis patients

Chertow, Glenn M.; Michael Lazarus, J.; Lew, Nancy L.; Ma, Lihong; Lowrie, Edmund G. (1997)

On the properties of the Dickey-Pantula test against fractional alternatives

Dolado, Juan José; Mármol, Francesc (1997)
The limit properties of the testing sequence underlying the Dickey-Pantula test for a double unit root in a time series are derived when the true data generating process is assumed to be nonstationary fractionally integrated. Publicado
