1. Craving for heroin: difference between methadone maintenance therapy patients with and without ADHD
Resumo Introdução O transtorno de déficit de atenção e hiperatividade (TDAH) é um transtorno do neurodesenvolvimento que persiste na idade adulta em 40-60% dos casos. Estudos clínicos e de neuroimagem sugerem que pacientes afetados tanto por adição quanto por TDAH apresentam maiores índices de fissura (craving) por droga do que pacientes sem TDAH

2. A Blue BRICS, Maritime Security, and the South Atlantic
Abstract Analysts frequently label the BRICS grouping of states (Brazil, India, Russia, China, and South Africa) as primarily an economic club emphasising economic performances as primary objectives. Co-operation of international groupings are rarely, if ever, set within the context of their access to maritime interests, security, and benefits. A second void

3. Abordagens para aprendizado semissupervisionado multirrótulo e hierárquico / Multi-label and hierarchical semi-supervised learning approaches
In machine learning, the task of classification consists on creating computational models that are able to automatically identify the class of objects belonging to a predefined domain from a set of examples whose class is known a priori. There are some classification scenarios in which each object can be associated to more than one class at the same time. Mo

4. Análise do ordenamento dos atrativos de turismo de base comunitária no Território da Serra do Brigadeiro-MG / Ranking analysis of the attractions of community-based tourism in the Territory of Serra do Brigadeiro-MG
In the present research work we constructed a set of atrices that allowed the characterization of the community-based tourism activity, using the project Good Practices of Community-Based Tourism developed in the Territory of Serra do Brigadeiro, Minas Gerais, Brazil. Tourism potential is a commonly term used to refer to a natural gift of a region and which,

5. O Conteúdo jurídico do conceito de beneficência estrita em face da experiência neoeugênica : do limite entre técnicas terapeuticas e reprodutivas e práticas eugênicas da espécie humana.
The author presents this studys problematic: can the biotechnological practices for assisted reproduction and genic therapy violate the individuals fundamental rights as well as cause damaging repercussions in the genetics patrimony of the humanity? From this thematic: The juridical content of the concept of strict beneficence in face of the neo-eugenic expe

6. Estudos da dinâmica estrutural da proteína ligante de cálcio S100A12 humana e da lisozima T4 / Structural dynamics studies of human calcium binding protein S100A12 and T4 lysozyme
The work presented here was conceived with two main objectives. The first one, more general, involved the implementation of a new methodology for the study of conformational changes in proteins, i.e., its structural dynamics. The technique of Site-directed Spin Labeling combined with Electronic Paramagnetic Resonance (SDSL-EPR) are the pillars of this new me

7. O uso de redes neurais auto-organizÃveis na anÃlise da transferÃncia de conhecimentos prosÃdico em aprendizes brasileirios de lÃngua inglesa / The use of self-organizing artificial neural networks for the analysis of prosodic knowledge in Brazilian learner of English
The objective of this dissertation was to investigate how the prosodic knowledge is organized in an early stage of L2 acquisition in Brazilian learners of English with the help of a connectionist neural network. The approach proposed in this research is first, to quantify the utterances of L2 learners in the form of LPC coefficients and other linguistic/phon

8. Classificação multi-rótulo hierárquica de documentos textuais
The amount of information stored in text databases is steadily increasing. As such, demand for automated techniques to organize this data also continues to grow. In this context, academic and industry research has been focused on the study of automatic text classification. Most work on text classification studies the development of techniques in which there

9. MineraÃÃo de regras para seleÃÃo de tÃcnicas de agrupamento para dados de expressÃo gÃnica de cÃncer
Different algorithms have been used to cluster gene expression data, however there is no single algorithm that can be considered the best one independently of the data. In this work, we applied the concepts of Meta-Learning to relate features of gene expression data sets to the performance of clustering algorithms. In our context, each meta-example represent

10. Otimização multi-objetivo aplicada à alocação dinâmica de rotas em redes de telecomunicações
The new networking technologies and the Internet difusion produced the data traffic increase in the networks. The quality of service (QoS) requirements for applications also increased and become stricter. Different QoS metrics can be evaluated by applications, for example the delay, the load balance and the packets lost in the communication.Different optimiz

11. A machine learning approach to automatic music genre classification
This paper presents a non-conventional approach for the automatic music genre classification problem. The proposed approach uses multiple feature vectors and a pattern recognition ensemble approach, according to space and time decomposition schemes. Despite being music genre classification a multi-class problem, we accomplish the task using a set of binary c
