1. Utilização da técnica de co-krigagem com inclinação máxima e altitude do terreno no delineamento de zonas de manejo: granulometria do solo e disponibilidade hídrica / Using the technique of cokriging with maximum slope of the terrain and altitude in the delineation of management zones: grain size and soil water availability
In Brazil, few studied are related about soil sampling strategies in areas with more than one type soil and various features of the landscape, these strategies are important to map the spatial variability of physical attributes: size fractions, as well as the correlation of these with geomorphologic parameters: altitude and maximum slope of the sampled area

2. Métodos geoestatísticos de co-estimativas: aplicação aos dados do Campo Escola de Namorado / Co-estimation geostatistical methods: applications to the Namorado Oil Field data
Data used for studying petroleum reservoirs are obtained through drill core, well logs, seismic records and, as a consequence, they present different sampling scales. Multivariate geostatistics is a manner of integrating these data in order to co-estimate a poorly sampled variable based not only on its own information but also on a densely sampled variable.

3. Co-estimation geostatistical methods: a study of the correlation between variables at results precision / Métodos geoestatísticos de co-estimativas: estudo do efeito da correlação entre variáveis na precisão dos resultados
This master dissertation presents the results of a survey into co-estimation methods commonly used in geostatistics. These methods are ordinary cokriging, collocated cokriging and kriging with an external drift. Besides that ordinary kriging was considered just to illustrate how it does work when the primary variable is poorly sampled. As we know co-estimati

4. Mapeamento do potencial mineral para niquel e ouro no Cinturão Metassedimentar Nova Brasilandia - Rondonia por meio de logica nebulosa (fuzzi) e redes neurais artificiais / Mineral potential mapping for nickel and gold in Nova Brasilandia Metassedimentar Belt - Rondonia trough fuzzy logic and artificial neuraL networks
Analysis and integration of spatial data from different natures, particularly on Geographic Information Systems (GIS), is a well known technique in mineral prospection. The available tools and other ones recently developed can help prospection campaigns where there is not enough geologic and metalogenetic knowledge, as the Nova Brasilândia Metassedimentar B

5. Incorporação de informações secundárias para gerenciar o risco no planejamento de lavra de curto prazo. / Incorporation of secondary information for risk planning short time manage.
O planejamento de lavra de curto prazo é normalmente executado utilizando-se número reduzido de informações de sondagem. Para aprimorar o gerenciamento de riscos geológicos no planejamento de lavra de curto prazo é necessário utilizar um universo maior de informações. Como é normalmente inviável obter novas informações de sondagem, esta disserta

6. Variabilidade Espacial do Desenvolvimento e da Produtividade do Trigo â Triticum aestivum
This work had by objective to study and to model the spatial variability of variables relative at the wheat development cultivated in year 2003 in 22,62 ha pertain at Central Co-operative of Agricultural Research (COODETEC). Went used the cultivates Coodetec 101 (3,52 ha) and Coodetec 103 (18,10 ha). The samples went colected in gride of 50 x 50 m, totalized
