1. Incorporação de tecnologias nos sistemas de saúde do Canadá e do Brasil: perspectivas para avanços nos processos de avaliação
Garantir o acesso equitativo a tecnologias que têm qualidade, segurança, eficácia e custo-efetividade comprovados, bem como assegurar que sua utilização seja baseada em evidências científicas de qualidade, constitui um dos principais desafios dos modernos sistemas de saúde. A avaliação de tecnologias em saúde (ATS) é uma das estratégias mais usa

2. Gene regulatory network inference and analysis of multidrug-resistant Pseudomonas aeruginosa
BACKGROUND Healthcare-associated infections caused by bacteria such as Pseudomonas aeruginosa are a major public health problem worldwide. Gene regulatory networks (GRN) computationally represent interactions among regulatory genes and their targets. They are an important approach to help understand bacterial behaviour and to provide novel ways of overcomi

3. Estimação e previsão da estrutura a termo das taxas de juros usando técnicas de inteligência computacional / Term structure of interest rate modeling and forecasting using computational intelligence techniques
This work proposes the term structure of interest rates modeling and forecasting using computational intelligence techniques, based on data from the US and Brazilian fixed income markets. The yield curve modeling includes the use of some evolutionary computation methods like Genetic Algorithms, Differential Evolution and Evolution Strategies in comparison wi

4. Verificação de framework conceitual de avaliação do desempenho de equipes-cliente: investigação a partir da construção de mapas cognitivos de profissionais de TI atuantes em projetos de implantação ERP
With high degree of breadth on the organisation and interdependence with its processes, the deployment of integrated management systems (ERP Enterprise Resource Planning) is not a simple task. Project management failures, unmet expectations, lengthy deployment deadlines and costs that reach up to five times the value of product licensing itself are among the

5. A proposal towards resilient complex networks through evaluation and adaptation mechanisms
Attacks and failures tolerance of complex networks is related to the concept of vulnerability in different contexts, from biology and sociology to computer science and physics. Studies have revealed that the topologies of these networks are inherently vulnerable to failures of central elements. Complex adaptive systems, emergent in nature, are considered mor

6. The Geographical Information System (GIS) as a strategy in logistics decisions of physical distribution / O Sistema de Informação Geográfica (GIS) como estratégia nas decisões logísticas de distribuição física
The concept of logistics, which until the mid-50 was limited to physical distribution - transport docks and warehouses due to its beginnings in the great empires and armies, has become much more complex and comprehensive. Nowadays it integrates processes involving the entire geographic scope, encompassing material flows, information and products from the poi

7. Transições de fases em um processo de reação-difusão em metapopulações heterogêneas / Phase transitions in a reaction-diffusion process in heterogeneous metapopulations
Uma área de interesse destacado da Física Estatística é o estudo de sistemas que apresentam transições de fases para estados absorventes [1, 2]. Estes modelos têm sido estudados em redes que apresentam topologias complexas e heterogêneas [3, 4, 5]. Nesta dissertação, um modelo para caracterizar a transição de fases em um processo de reação-difu

8. Prediction of the level of Paraguay river using neural networks.
Backpropagation neural networks are implemented for prediction of the level of Paraguay River at Ladario city, MS. Using 274 monthly mean values, the trained network predicts the levels of the four next months with relative errors smaller than 17%. For some special points, the prediction results also show that the neural network method seems to be useful to

9. Um estudo sobre reconhecimento de padrões: um aprendizado supervisionado com classificador bayesiano / A study on pattern recognition: supervised learning with a Bayesian classier
The facility we have to recognize a face, to understand spoken words, reading manuscripts, identifying car keys in our pocket and deciding whether an apple is ripe by its smell, belie the complex processes that are behind the act to recognize these patterns. These recognitions have been crucial to our survival, and over the past tens of millions of years sop

10. Efficiency dynamics on two coupled small-world networks
We investigate the effect of clusters in complex networks on efficiency dynamics by studying a simple efficiency model in two coupled small-world networks. It is shown that the critical network randomness corresponding to transition from a stagnant phase to a growing one decreases to zero as the connection strength of clusters increases. It is also shown for

11. NavegaÃÃo em redes espacialmente correlacionadas. / Navigation in a spatially correlated network
A significant number of real networks have well-defined spatial characteristics. We studied how network with spatially correlated topolgies can influence the processes of navigation through them. For this, we study the behavior of the average shortest-path length to networks defined within Kleinbergâs model [1, 2] to analyze the navigation dictated by rules

12. Learning about brain physiology and complexity from the study of the epilepsies
The brain is a complex system, which produces emergent properties such as those associated with activity-dependent plasticity in processes of learning and memory. Therefore, understanding the integrated structures and functions of the brain is well beyond the scope of either superficial or extremely reductionistic approaches. Although a combination of zoom-i
