1. Time-series forecasting of pollutant concentration levels using particle swarm optimization and artificial neural networks
This study evaluates the application of an intelligent hybrid system for time-series forecasting of atmospheric pollutant concentration levels. The proposed method consists of an artificial neural network combined with a particle swarm optimization algorithm. The method not only searches relevant time lags for the correct characterization of the time series,

2. Técnicas e arquitetura para captura de traços e execução especulativa / Tecnhiques and architecture for trace detection and speculative execution
É sabido que o modelo de desenvolvimento de micro-processadores baseado na extração de Instruction-Level Parallelism (ILP) de código sequencial atingiu seu limite. Encontrar soluções escaláveis e eficientes que permitam a manutenção de inúmeras instruções em execução simultaneamente tem se mostrado um desafio maior que o imaginado. Neste sentid

3. Flexible tunable spectrum sliced microwave photonic filter using parallel Fabry-Pérot filters and Fiber Bragg Grating
A simple and low-cost spectrum sliced microwave photonic filter with high tunability has been implemented. This is based on use of two Fabry-Pérot filters with same free spectral range connected in parallel but one filter with an external fiber delay. An extension of this configuration with Fiber Bragg Grating (FBG) as delay element is also demonstrated. Th

4. Arquitetura compacta para projeto de robôs móveis visando aplicações multipropósitos / Compact architecture to design mobile robots for multipurpose applications
Com a necessidade de substituir o trabalho humano em áreas de risco, ambientes impróprios ou inalcançáveis, diversos centros de pesquisas e universidades têm desenvolvido aplicações e estratégias de controle para robôs móveis. Porém, o alto custo na aquisição de um ou mais protótipos para estudos e desenvolvimento de novas tecnologias pode se t

5. Development of a tridimensional surface digitaliztion system based on computer vision and laser scanning with metrological purpose / Desenvolvimento de um sistema de digitalização tridimencional de superfícies baseado em visão computacional com varredura a laser para uso em metrologia dimensional
Most of todays 3D laser scanning systems for object model digitalization rely on angular position sensors to measure rotation of a laser diode and to reconstruct the object. However, those types of sensors restrict the object size in target and its distance from the image sensor, since reconstruction is usually based on equations for geometric triangulation,

6. A middleware for service orchestration in computacional grids / GPO : um middleware para orquestração de serviços em grades computacionais
In the collaborative environment of the Computational Grids, there are few tools used for process management and user guide services. This work presents the Grid Process Orchestration (GPO), an infrastructure for service and process orchestration in computational grids, which allows to create and manage complex workflows composed of strongcoupled jobs with n

7. Remodeling of the human dermis after application of salicytate silanol / Remodelamento da derme humana apos aplicação de salicilato de silanol
Mesotherapy is a technique that lacks scientifical clinical trials. In 2005, a controlled double-blind study in patients with photo-aged facial skin demonstrated the beneficial role of oral intake of silanol for skin, hair and nails. Facing it, a study was developed to compare histological alterations in human skin that received intradermal injections of sil

8. The homeobox gene BREVIPEDICELLUS is a key regulator of inflorescence architecture in Arabidopsis
Flowering plants display a remarkable range of inflorescence architecture, and pedicel characteristics are one of the key contributors to this diversity. However, very little is known about the genes or the pathways that regulate pedicel development. The brevipedicellus (bp) mutant of Arabidopsis thaliana displays a unique phenotype with defects in pedicel d

9. Structural and functional characterization of the poliovirus replication complex.
Two populations of membrane-bound replication complexes were isolated from poliovirus-infected HEp-2 cells by sucrose gradient centrifugation. The two fractions show similar ultrastructural features: the replication complex is enclosed in a rosettelike shell of virus-induced vesicles and contains a very tightly packed second membrane system (compact membrane

10. The microvascular architecture of the choroid plexus in fetal human brain lateral ventricle: a scanning electron microscopy study of corrosion casts
The microvascular architecture of developing lateral ventricle choroid plexus was investigated by corrosion casting and scanning electron microscopy in human fetuses aged 20 gestational weeks. The areas with different microvascular patterns corresponded to the particular parts of the mature plexus: anterior part, glomus, posterior part, the villous fringe an

11. Unique mitochondrial genome architecture in unicellular relatives of animals
Animal mtDNAs are typically small (≈16 kbp), circular-mapping molecules that encode 37 or fewer tightly packed genes. Here we investigate whether similarly compact mitochondrial genomes are also present in the closest unicellular relatives of animals, i.e., choanoflagellate and ichthyosporean protists. We find that the gene content and architecture of the

12. An architect's perspective on contemporary academic library design.
The making of space and place (architecture) requires cultural and financial consent as to societal value. Standards and values about the academic library of the immediate future are not always shared by librarians and architects; however, architects and librarians do possess several shared perceptions. Among these shared perceptions are that print collectio
