13. DSI-RTree - Um Índice R-Tree Distribuído Escalável / DSI-RTree - A distributed Scalable R-Tree Index
Em face de um mundo computacional ubíquo cada vez mais possível, tem crescido constantemente a necessidade de sistemas de processamento de dados espaciais que suportem a criação de aplicações massivas para explorar a grande quantidade de dados existente, a fim de auxiliar a vida cotidiana das pessoas e prover novas ferramentas para empresas e governo.

14. Comunidade e partilha ecológica de turdídeos (Aves: Passeriformes) em um fragmento urbano de floresta com araucárias em Guarapuava no Sul do Brasil / Community and ecological partitioning of trhushes (Aves: Passeriformes) in a urban forest fragment with araucaria in Guarapuava, southern Brazil
Ecological mechanisms that allow the coexistence of five species of the genus Turdus (Turdidae) in an urban fragment in souther Brazil seem to be not easily explained. In this context, the present work tried to comprehend how the birds community is structured as well as to investigate possible patterns and mechanisms that make possible the coexistence of two

15. Variación florística de especies arbóreas a escala local en un bosque de tierra firme en la Amazonia colombiana
This study was carried out in a 5-ha permanent plot established in the Amacayacu National Park, Colombian Amazonia. We assessed the extent at which floristic patterns of tree species were determined by either the environmental variation or the spatial configuration in tierra firme forests. Floristic and environmental variation was assessed on quadrants of 20

16. ChipCFlow - partioning and communication protocol in the dynamic dataflow graph / ChipCFlow - Partição e protocolo de comunicação no grafo a fluxo de dados dinâmico
This work describes the concept of an approach that uses data ow computational model, inherently parallel, associated with de reconfigurable computing model, partial and dynamic, in order to obtain high performance computational systems. More specifically, it is about a model to the partitioning and communication between partitioned sectors of a CDFG (Contro

17. Enxame de partículas aplicado ao agrupamento de textos / Enxame de partículas aplicado ao agrupamento de textos
The large number of data generated by people and organizations has stimulated the research on effective and automatic methods of knowledge extraction from databases. This dissertation proposes two new bioinspired techniques, named cPSC and oPSC, based on the Particle Swarm Optimization Algorithm (PSO) to solve data clustering problems. The proposed algorithm

19. Metaheurísticas para o problema de agrupamento de dados em grafo / Metaheuristics for the graph clustering problem
Graph clustering aims at identifying highly connected groups or clusters of nodes of a graph. This problem can assume others nomenclatures, such as: graph partitioning problem and community detection problem. There are many mathematical formulations to model this problem, each one with advantages and disadvantages. Most of these formulations have the disadva

20. Composição isotópica e fluxos de CO2 em área de Cerrado (Parque Estadual de Vassununga, SP) / Isotopic composition and carbon dioxide fluxes in an area of Cerrado (State Park of Vassununga, SP)
The presente study was carreid out in area o Cerrado strictu senso located at the State Park of Vassununga, closed to the Santa Rita do Passa Quatro city, São Paulo State, Brazil. The aim was of the present work was to measure de CO2 fluxes released through respiration processes of the vegetation and soil (heterotrophic and autotrophic) to check the relativ

21. Uso do sensoriamento remoto orbital e de superfície para o estudo do comportamento espectral do corpo de água do reservatório de Manso, MT, Brasil / Use of orbital and surface remoto sensing to the study of the spectral signature of the reservoir water Body, MT, Brazil
The monitoring of water quality of a reservoir allows for preservation of the environment as well as bringing social-economic benefits. Remote Sensing accomplishes this monitoring in a synoptic way, because it considers spatial and time scales necessary to evaluate an aquatic ecosystem. For this, a Moderate Resolution Imaging Spectroradiometer (MODIS) sensor

23. Morphological and structural constraints on the dynamics of the river basin of the River Benevente - Espírito Santo / Condicionantes morfológicos e estruturais na dinâmica fluvial da bacia hidrográfica do Rio Benevente - Espírito Santo
The study of watersheds in the humid tropical environment, has acquired great importance in recent decades due to growing demand for water resources planning. However, many studies have confused the concept of watersheds, believing that this was simply a network of interconnected channels that form the hydrography of the land, thus making it as simple cartog

24. Compositional abstraction of CSP Z processes
Data abstraction is a powerful technique to overcome state explosion in model checking. For CSP Z (a formal integration of the well-known specification languages CSP and Z), current approaches can mechanically abstract infinite domains (types) as long as they are not used in communications. This work presents a compositional and systematic approach to data a
