2. GRAPHICAL REPRESENTATION ANALYSIS OF COMPLEMENTARY CIVIL PROJECTS USING "CAD 2D", "BIM" AND "RA" AND IDENTIFICATION OF INTERFERENCES
Abstract Technical graphic representation presents problems concerning the reduction of dimensionality from 3D to 2D. AEC (architecture, engineering and construction) projects usually adopt the top view paradigm with two-dimensional orthogonal projection. Recently, three major changes in technical representation were the alteration of orthogonal projection i

3. New insights into genomic selection through population-based non-parametric prediction methods
ABSTRACT: Genome-wide selection (GWS) is based on a large number of markers widely distributed throughout the genome. Genome-wide selection provides for the estimation of the effect of each molecular marker on the phenotype, thereby allowing for the capture of all genes affecting the quantitative traits of interest. The main statistical tools applied to GWS

4. CLASS-BASED AFFINITY PROPAGATION FOR HYPERSPECTRAL IMAGE DIMENSIONALITY REDUCTION AND IMPROVEMENT OF MAXIMUM LIKELIHOOD CLASSIFICATION ACCURACY
Resumo Este artigo investiga um método de classificação alternativo que integra o algoritmo de clusterização propagação de afinidade baseado nas classes (PAC) e o Classificador Máxima Verossimilhança (MAXVER) com a finalidade de superar as limitações do MAXVER na classificação de dados de alta dimensionalidade e, assim, melhorar a sua acurácia.

6. Automatic Identification of Cigarette Brand Using Near-Infrared Spectroscopy and Sparse Representation Classification Algorithm
A cigarette brand automatic classification method using near-infrared (NIR) spectroscopy and sparse representation classification (SRC) algorithm is put forward by the paper. Comparing with the traditional methods, it is more robust to redundancy because it uses non-negative least squares (NNLS) sparse coding instead of principal component analysis (PCA) for

7. Determinants of oral self-care in the Brazilian adult population: a national cross-sectional study
Abstract: This study aims to investigate variables related to adherence to oral self-care in the Brazilian adult population. It is an exploratory study, using secondary data from a population-based survey on a representative sample of the adult population of the entire Brazilian territory (n=60202). The sample was selected using a multiple stage approach. Th

8. Heartbeat classification system based on neural networks and dimensionality reduction
Abstract Introduction This paper presents a complete approach for the automatic classification of heartbeats to assist experts in the diagnosis of typical arrhythmias, such as right bundle branch block, left bundle branch block, premature ventricular beats, premature atrial beats and paced beats. Methods A pre-processing step was performed on the electroca

9. FReMI: a middleware to handle molecular docking simulations of fully-flexible receptor models in HPC environments
Molecular docking simulations of Fully-Flexible Protein Receptor (FFR) models are coming of age. However, they are computer intensive and their sequential execution can became an unfeasible task. This study presents a middleware, called Flexible Receptor Middleware (FReMI), to assist in faster docking simulations of flexible receptors. FReMI handles intensiv

10. Variantes genéticas de risco para a dependência de crack/cocaína: estudo de associação do tipo gene candidato e epistasia / Genetic risk variants for crack/cocaine dependence:gene candidate association study and epistasis
O uso da cocaína e do crack tornou-se um problema de saúde pública importante no Brasil por conta de prejuízos significativos do ponto de vista médico, psicológico e social que ele acarreta. Estudos de gêmeos e, em famílias, sugerem que a dependência de cocaína é uma doença complexa, com participação importante de fatores genéticos. Os estudos

11. Abordagens multi-objetivo para o treinamento de redes neurais e seleção de características
Artificial neural networks have been successfully applied in solving problems such as functions approximation and patterns classification, where the extraction of a model can be difficult to see. The search for a model that best represents the problem makes the generalization ability the main concern in the training of artificial neural networks, a task that

12. FBG optimization using spline encoded evolution strategy
This paper presents an encoding scheme adapted for Fiber Bragg Grating (FBG) optimization using metaheuristics. The proposed encoding scheme uses spline approximations in order to build softened refractive index profiles from few encoded parameters. This approach is suitable for Fiber Bragg Grating (FBG) synthesis because it ensures both the reduction of the
