1. DEVELOPMENT OF SOFTWARE FOR ANALYSIS OF BEHAVIOR AND WELFARE OF BROILERS
ABSTRACT The objective of this study was to develop a software based on image processing and computer vision techniques for monitoring the feeding/collective behavior of broilers (Cobb) and validate it based on the results obtained from the visual analysis of an expert. The visual analysis was performed based on the observation and quantification of behavior

2. BIBLIOMETRIC MAPPING OF PAPERS ON GEOGRAPHICAL INFORMATION SYSTEMS (2007-2016)
Abstract The amount of researchers and scientific papers rapidly grows, annually. The metrics to analyze the quality and quantity of these publications have consolidated in the academic world. A bibliometric mapping of scientific papers on Geographic Information Systems (GIS) published between 2007 and 2016 was carried out. The sample analyzed 2,053 papers,

3. Enterobacterial repetitive intergenic consensus (ERIC)-PCR analysis as a reliable evidence for suspected Shigella spp. outbreaks
Abstract Background Shigellosis remains a serious public health problem and an important cause of morbidity and mortality worldwide. The aim of this study was to characterize fliC and the genetic relatedness of Shigella spp. isolated during a one-year period from children in a suspected outbreak in Tehran, Iran. Methods and results Fifty Shigella spp. were

4. Analysis of genetic population structure in Acacia caven (Leguminosae, Mimosoideae), comparing one exploratory and two Bayesian-model-based methods
Bayesian clustering as implemented in STRUCTURE or GENELAND software is widely used to form genetic groups of populations or individuals. On the other hand, in order to satisfy the need for less computer-intensive approaches, multivariate analyses are specifically devoted to extracting information from large datasets. In this paper, we report the use of a da

5. Uso de análise multivariada para determinar a associação do desempenho reprodutivo de machos suinos com as caracteristicas seminais / Use of multivariate analyses to determine the association of boar fertility with semen traits
The application of new approaches that measure certain sperm motion characteristics and their association with boar fertility has shown a recent increase. Computer-assisted semen analysis (CASA) offers standardized assessment of multiple sperm motion parameters and it is plausible that the combination of these parameters with morphological sperm defects may

6. A scalable multi-projector system. / Um sistema de multiprojeção escalável.
Multi-projector systems offer both higher resolution and brightness by using a cluster of projectors, providing better visual quality when compared to traditional systems using a single high performance projector. When we consider the high cost associated with high-end projectors, the use of multiple low cost projectors can reduce considerably the cost of su

7. Continuously variable rating: a new, simple and logical procedure to evaluate original scientific publications
OBJECTIVE: Impact Factors (IF) are widely used surrogates to evaluate single articles, in spite of known shortcomings imposed by cite distribution skewness. We quantify this asymmetry and propose a simple computer-based procedure for evaluating individual articles. METHOD: (a) Analysis of symmetry. Journals clustered around nine Impact Factor points were sel

8. Aceleração da deformação interativa de corpos sólidos usando GPU / GPU acceleration for interactive solid bodies deformation
Aplicativos que visam simular o comportamento físico de corpos deformáveis são importantes ferramentas científicas, também exploradas em jogos e animações computacionais. O primeiro passo para fazer uma simulação é modelar o corpo que se deseja simular, e quanto mais preciso o modelo, maior será o conjunto de dados gerados. Para gerar gráficos co

9. Investigação teórica da quimisssorção do ânion metanossulfonato em eletrodos de platina (111) e (100) via método semi-empírico
Several electrochemical processes, such as electrocatalysis of organic substrates, make use of mediators. One of the mediators is the most commonly used anion methanesulfonate, CH3SO3, which has several advantages for such use, and chemical stability considered one of them. However, experimental studies indicate the possibility of this compound suffer the ad

11. Estudo da adsorção do líquido iônico [BMIM]+[BF4]sobre γ-Al2O3 por cálculos ab initio
Ionic liquids are, by definition, salts formed by an organic cation and an inorganic anion, with a low melting point. An important application of ionic liquids is that they can replace conventional solvents. Recently, they were also used as cocatalysts (in the form of solvents) for metallic clusters, in the process of removal of aromatics from petroleum. The

12. Implementação e análise de algoritmos BSP/CGM em um Beowulf e no InteGrade
As the science and technology advanced in all diverse areas, problems which require more and more computer power to be solved were risen. In the beginning, these problems were solved by high performance parallel computers which were huge and very expensive. After that, though, making clusters with PCs which worked together to offer a higher processing capaci
