1. Cost-utility of quadrivalent versus trivalent influenza vaccine in Brazil – comparison of outcomes from different static model types
ABSTRACT Background: Influenza burden in Brazil is considerable with 4.2–6.4 million cases in 2008 and influenza-like-illness responsible for 16.9% of hospitalizations. Cost-effectiveness of influenza vaccination may be assessed by different types of models, with limitations due to data availability, assumptions, and modelling approach. Objective: To und

2. Bacteria arise at the border of mycoplasma-infected HeLa cells, containing cytoplasm with either malformed cytosol, mitochondria and endoplasmic reticulum or tightly adjoined smooth vacuoles
ABSTRACT A study with transmission electron microscopy of mycoplasma-contaminated HeLa cells using five cell donors referred to as donors A, B, C, D and E, observations are herein presented. Experiments performed with cells from donors B, C and D, revealed the presence of Mycoplasma hyorhinis after PCR and sequencing experiments. Bacteria probably originated

3. A novel transition identification mechanism for the diesel blending and distribution scheduling problem using the discrete time representation with two time-scales granularity
ABSTRACT Transitions between tasks arise in many different scheduling problems. Sometimes transitions are undesired because they incur costs; sometimes they are undesired because they require setup time, and sometimes both. In one way or the other, frequently, transitions need to be identified and penalized in order for their frequency to be minimized. The p

4. DISCOVERING AND LABELLING OF TEMPORAL GRANULARITY PATTERNS IN ELECTRIC POWER DEMAND WITH A BRAZILIAN CASE STUDY
ABSTRACT Clustering is commonly used to group data in order to represent the behaviour of a system as accurately as possible by obtaining patterns and profiles. In this paper, clustering is applied with partitioning-clustering techniques, specifically, Partitioning around Medoids (PAM) to analyse load curves from a city of South-eastern Brazil in São Paulo

5. Conidial germination in Scedosporium apiospermum, S. aurantiacum, S. minutisporum and Lomentospora prolificans: influence of growth conditions and antifungal susceptibility profiles
In the present study, we have investigated some growth conditions capable of inducing the conidial germination in Scedosporium apiospermum, S. aurantiacum, S. minutisporum and Lomentospora prolificans. Germination in Sabouraud medium (pH 7.0, 37ºC, 5% CO2) showed to be a typically time-dependent event, reaching ~75% in S. minutisporum and > 90% in S. apiosp

6. The Prediction of the Man-Hour in Aircraft Assembly Based on Support Vector Machine Particle Swarm Optimization
ABSTRACT: As the representative of manufacturing industry, aircraft assembly lacks of effective method to forecast man-hour. The forecasting accuracy of existing methods is universally pretty low. On the basis of full analysis of aircraft assembly's feature, this study proposes a forecasting model based on support vector machine (SVM), which is optimized by

7. Aprendizado não supervisionado de hierarquias de tópicos a partir de coleções textuais dinâmicas / Unsupervised learning of topic hierarchies from dynamic text collections
The need to extract new and useful knowledge from large textual collections has motivated researchs on Text Mining methods. Among the existing methods, initiatives for the knowledge organization by topic hierarchies are very popular. In the topic hierarchies, the knowledge is represented by topics and subtopics, and each topic contains documents of similar c

8. Uma proposta de escalonamento distribuído para exploração de paralelismo na programação em lógica / A distributed scheduler proposal for exploration of parellelism in logic programming
Este trabalho apresenta um modelo de escalonamento hierárquico para exploração do paralelismo E Independente e do paralelismo OU na programação em lógica. O modelo utiliza informações de granulosidade geradas pelo GRANLOG (Granularity Analyzer for Logic Programming) para o auxílio ao escalonamento. Um estudo detalhado de ambientes de programação e

10. Processamento, caracterização e estudo de fenômenos críticos do sistema supercondutor (Y - Er)Ba2Cu3O7
The effect of Er substitution on the mechanical properties of ab and a(b)c planes of melt-textured Y Ba2Cu3O7 is reported in the present work. The samples were characterized by scanning electron microscopy, X-ray diffraction, resistivity measurements and mechanical properties by instrumented indentation and conventional Vickers measurement. The X-ray pattern

11. Uma extensão nativa de sql para mineração de trajetórias semânticas / A native extension of SQL for semantic trajectory data mining
O objetivo principal deste trabalho é desenvolver uma extensão nativa do SQL para a mineração de trajetórias de objetos móveis. As trajetórias são representadas por stops e moves, e o processo contempla as etapas de pré-processamento, extração de padrões seqüenciais e pós-processamento. Através do método proposto, baseado em uma árvore de pr

12. Controle de granularidade com threads em programas MPI dinâmicos / Controlling granularity of dynamic mpi programs with threads
Nos últimos anos, a crescente demanda por alto desempenho tem favorecido o surgimento de arquiteturas e algoritmos cada vez mais eficientes. A popularidade das plataformas distribuídas levanta novas questões no desenvolvimento de algoritmos paralelos tais como comunicação, heterogeneidade e dinamismo de recursos. Estas questões podem resultar em aplica
