1. Annual cropland mapping using data mining and OLI Landsat-8
RESUMO No Estado do Paraná, Brasil, não há grandes mudanças nas áreas cultivadas com culturas anuais, principalmente devido a leis ambientais que não permitem expansões para novas áreas. Há grande contribuição das culturas anuais para a demanda doméstica de alimentos e econômica nas exportações. Assim, a área e distribuição das culturas anu

2. Estimating Stand Height and Tree Density in Pinus taeda plantations using in-situ data, airborne LiDAR and k-Nearest Neighbor Imputation
ABSTRACT Accurate forest inventory is of great economic importance to optimize the entire supply chain management in pulp and paper companies. The aim of this study was to estimate stand dominate and mean heights (HD and HM) and tree density (TD) of Pinus taeda plantations located in South Brazil using in-situ measurements, airborne Light Detection and Rangi

3. Performance evaluation of images by content search in computer networking / Avaliação do desempenho de busca de imagens por conteúdo em redes de computadores: uma proposta de reengenharia com aplicação a imagens médicas
O objetivo deste trabalho é avaliar a recuperação de imagem por conteúdo (CBIR - Content-based Image Retrieval) em uma rede de computadores, estabelecendo-se métricas de controle que otimizem a utilização da rede e ao mesmo tempo garanta melhor qualidade na resposta. Prevê-se a recuperação de imagens baseada em consulta por similaridade, combinando

4. Aproximação de métricas finitas por métricas arbóreas e aplicações / Approximation of finite metrics by tree metrics and applications
Many optimization problems on graphs, especially metric problems, are easier to solve on trees. Therefore, a strategy for obtaining a good algorithm for certain problems is to obtain a tree that approximates the graph, and use a solution of the problem on the tree as an approximate solution for the problem on the original graph. We study the work of Fakcharo

5. Besouros escarabeÃneos em fragmentos de Floresta AtlÃntica do Centro de Endemismo Pernambuco
Habitat fragmentation alters the dynamics of tropical tree assemblages, being able to modify the dung beetles communities. The objective of this research was to determine how the fragments metrics and functional attributes of trees assemblages influence the dung beetles communities in Atlantic forest fragments of northeastern Brazil. The collecting of dung b

6. Algoritmos genéticos multiobjetivos aplicados ao roteamento multicast com qualidade de serviço
Multicast Routing is an effective way to communicate between multiple routers into computer networks. In general, the quality of service (QoS) is required in most of multicast applications. Several researchers have investigated the application of genetic algorithms in multicast Routing with QoS restrictions. The evolutionary environments proposed in this dis

7. Characterization of the shrub and tree vegetation from Montane Ombrophilous Dense Forest fragments / Caracterização da vegetação arbustivo-arborea de fragmentos de Floresta Ombrofila Densa Montana
The Atlantic Forest possesses enormous biodiversity and is highlighted by the high floristic diversity and endemism in some plant groups. The Atlantic Forest is among the most endangered tropical forests in the world and most of its remnants are small and altered fragments, or larger areas in mountains, with pronounced slope. Knowledge of the forest remnants

8. Caracterização física, estrutural e da diversidade floristica de fragmentos florestais na alta bacia do Rio Araguaia
The upper Araguaia river basin region has been transformed by rapid and intensive human occupation processes that began in the 1970s, and now the landscape is highly fragmented. Remnant forests are surrounded by cotton and soybean plantations and pasture. They continue to be subjected to degradation and little is known about their ecological integrity. The o

10. Adaptability, reusability and variability in software systems for space on-board computing.
Software industry is currently moving towards automation of business processes and applications increasing architectural complexity and the dynamics of requirements change. This work proposes a novel software development process, called SPAREv that includes all todays critical innovations on four areas: Model-Driven Development (MDD); Systematic Reuse; Devel

11. Busca e recuperaÃÃo de componentes de software utilizando agrupamento de componentes
The development of software with reuse is an approach that can be used to achieve two main benefits: (1) increase in productivity of software projects and (2) improvements in the final quality of the products. The software reuse approach can be instantiated through the strategy of development based in software components. According to this strategy, large so

12. Decomposition and width in tree of graphs to glide free of cycles induced pairs / DecomposiÃÃo e largura em Ãrvore de grafos planares livres de ciclos pares induzidos.
The definitions of tree decomposition and treewidth were introduced by Robertson and Seymour in their series of papers on graph minors, published during the nineties. It is known that many NP-hard problems can be polynomially solved if a tree decomposition of bounded treewidth is given. So, it is of interest to bound the treewidth of certain classes of graph
