13. Análise multi-temporal de cenas do satélite quickbird usando um novo paradigma de classificação de imagens e inferências espaciais. Estudo de caso: Belo Horizonte, MG / Multi-temporal analysis of quickbird images using a new classification paradigm and spatial inferences. A case study: Belo Horizonte - MG, Brazil
Due to the strong urbanization process occurring in Brazil and of population increase in cities, and consequently to serious impacts on environment, there is a growing need to develop methodologies and technologies which allow to monitor, analyze and to make an intervention at the urban expansion. Belo Horizonte (State Capital of Minas Gerais) is a highly co

14. DBSitter: um sistema inteligente para gerencimaneto de SGBD
By analyzing the daily work of Data Base Administrators (ABD), we perceived that a large amount of problems (e. g. performance tuning, security and physical dimensioning) occur repetitively. Nonetheless, the professionals normally forget the best solution for them, especially when working under pressure. Remembering the correct solution may take a long time

15. Analise experimental das aplicações de codigos corretores de erro em sistemas de comunicações opticas
This work presents an experimental analysis on the use of error correcting codes in optical communication systems, specifically by means of the Forward Error Correction (FEC) technique. Two electronic modules were designed and assembled during the experimental stages of the work - a coding and decoding module, which uses the Reed-Solomon RS (255,241) code, a

16. Assinaturas espectrais de gossans associados a mineralizações de Pb-Zn-Ba na Bacia de Irece (BA) : um estudo baseado em dados de sensores TM e ASTER
The aim ofthis work was to develop strategies for detection ofgossans associated to Pb-Zn-Ba deposits in the Irece basin (BA), as well as their distinction ftom generic laterites, using remote sensing data and techniques. Samples of gossans collected in the study area were analysed by reflectance spectroscopy methods, using a high resolution FieldSpec FR spe

17. Development of a tool for the automatic creation and correction of tests on the Word-Wide-Web. / Desenvolvimento de uma Ferramenta para Criação e Correção Automáticas de Provas na World-Wide-Web.
A World-Wide Web (WWW) tem se desenvolvido enormemente, facilitando o compartilhamento de informações. Muito rapidamente as aplicações do seu potencial educacional se tornaram aparentes, especialmente para a Educação à Distância (ED). Neste sentido, a WWW possui um maior apelo, devido a sua capacidade de exibição de documentos multimídia, capacida

18. Simulação numerica de reservatorios utilizando um metodo de implicitude auto-adaptavel
This work presents the development and application of a reservoir simulation method, based on a variable ando auto-adaptive implicit formulation. The variable implicitness formulation is based on a general approach of reservoir simulation methods, already presented in the literature. In such approach a basic leveI of implicitness for alI methods is recognize

19. A HYBRID ERROR-CONTROL STRATEGY FOR A PACKET RADIO NETWORK / UMA ESTRATÉGIA DE CONTROLE DE ERRO HÍBRIDA PARA UMA REDE DE PACOTE VIA RÁDIO
Este trabalho apresenta o desenvolvimento de uma estratégia de controle de erro híbrida baseada em correção de erro (FEC- Forward Error Correction) e protocolo de retransmissão (ARQ-Automatic Repeat Request) para uma Rede de Pacote Via Rádio (PRNET- Packet Radio Network). O controle de erro tem como objetivo garantir a integridade dos dados e manter o

20. Automatic Detection of Cardiac Arrest Rhythms Prior to Automatic External Cardiac Defibrillation
The detection and correction of ventricular fibrillation at the earliest time after its onset is essential to ensure long-term survival. During successive cardiac arrests the rhythms occurring were sensed by using disposable pre-gelled ECG defibrillator pads placed in the anterior-anterior position. Simultaneously with the treatment, the arrest rhythms were

21. High counting rates from 125I in radioimmunoassays
Responses from one manual and four automatic gamma counters for assaying 125I were compared. The resolution times quoted by manufacturers when applied in a standardized correction formula to obtain true counts from observed counting rates above 104 counts per second appeared to be inadequate. The need to investigate the errors associated with high counting r

22. Dry-heat destruction of lipopolysaccharide: design and construction of dry-heat destruction apparatus.
A dry-heat oven with automatic, multiple-sample introduction and withdrawal has been constructed to achieve instantaneous heating and cooling of samples. The oven temperature fluctuation at set points of 170 to 250 degrees C was +/- 0.1 degrees C, with temperature variation between the replicate samples of +/- 0.2 degrees C. Correction required for a sample

23. Nerve fibre velocity and refractory period distributions in nerve trunks.
With the use of a double stimulus technique, nerve fibre velocity range measurements were performed over a single conduction distance in 13 normal subjects and over two conduction distances in another 12 normal subjects. The velocity ranges were found to be dependent upon the conduction distance, owing to unknown refractory period delays. Refractory period v

24. Plasticity in the binocular correspondence of striate cortical receptive fields in kittens.
The influence of visual experience on the correspondence in position and orientation of receptive fields in the two eyes of cortical neurones was studied. Kittens were reared viewing the environment through lenses that magnified the image by 9% in one direction (meridional size lenses) with axes of magnification oriented 45 degrees left and right of vertical
