4. Breast cancer diagnosis based on mammary thermography and extreme learning machines
Abstract Introduction Breast cancer is the most common cancer in women and one of the major causes of death from cancer among female around the world. The early detection and treatment are the major way to healing. The use of mammary thermography in Mastology is increasing as a complementary imaging technique to early detect lesions. Its use as a screening

5. Modeling Bayesian Networks from a conceptual framework for occupational risk analysis
Abstract Occupational risk is the possibility that some element included in a particular work environment can cause damage to someone’s health. Thereby, the risk is understood as the product of probability and consequences. In this sense, risk analysis through probabilistic stochastic techniques, such as Bayesian networks (BN), becomes an important tool to

6. QSAR Study of the Inhibitors of the Acetyl-CoA Carboxylase 1 and 2 using Bayesian Regularized Genetic Neural Networks: A Comparative Study
Linear and non-linear quantitative structure-activity relationship (QSAR) models were presented for modeling and predicting anti-diabetic activities of a set of inhibitors of acetyl-CoA carboxylase 1 and 2 (ACC1 and ACC2). Different algorithms were utilized to choose the best variables among large numbers of descriptors and then these selected descriptors we

7. New strategies for planning and performance evaluation of wireless networks: case studies based on the cross-layer approach
The use of wireless local area networks, called WLANs, as well as the proliferation of the use of multimedia applications have grown rapidly in recent years. Some factors affect the quality of service (QoS) received by the user and interference is one of them. This work presents strategies for planning and performance evaluation through an empirical study of

8. Dificuldades orçamentárias básicas das famílias brasileiras: um convite à reflexão a partir de redes bayesianas / Basic budgetary difficulties of Brazilian families: an invitation to reasoning from bayesian networks
Este estudo visa compreender a adequação dos rendimentos às necessidades e condições de vida dos brasileiros. Observando os dados da Pesquisa de Orçamentos Familiares (POF) realizada pelo IBGE (Instituto Brasileiro de Geografia e Estatística) para o período: 2008 e 2009, o estudo identifica um modelo que se concentra na investigação sobre o fato de

9. Sistema evolutivo eficiente para aprendizagem estrutural de redes Bayesianas / Efficient evolutionary system for learning BN structures
Redes Bayesianas (RB) são ferramentas probabilísticas amplamente aceitas para modelar e fazer inferências em domínios sob incertezas. Uma das maiores dificuldades na construção de uma RB é determinar a sua estrutura de modelo, a qual representa a estrutura de interdependências entre as variáveis modeladas. A estimativa exata da estrutura de modelo a

10. Um modelo para a análise de impacto em código fonte usando ontologias e recuperação de informação
Changes are inevitable during the product lifecycle. These changes are due different needs, such as the knowledge evolution of business processes, environment or infrastructure changes, etc. Under these circumstances, it is crucial to have the control about the knowledge of what these changes mean to the system. Impact analysis represents the process that cr

11. Detecção e classificação de arritmias em eletrocardiogramas usando transformadas wavelets, máquinas de vetores de suporte e rede Bayesiana
The cardiopathies are currently, according the Ministério da Saúde, the second biggest cause of mortality among the Brazilians, behind only the brain vascular diseases. The motivation for the work here presented is the identification and classification of cardiopathies registered in Electrocardiogram exams, ECG, such as premature contractions, branches blo

12. Aplicação de Redes Bayesianas para a análise de confiabilidade do sistema de regaseificação de uma unidade tipo FSRU. / The use of Bayesian Networks on reliability analysis of a regasification system on a FSRU.
A motivação para este trabalho originou-se da atual tendência do Gás Natural Liquefeito (GNL) se tornar uma importante opção para a diversificação da matriz energética brasileira. Atualmente, os terminais de gás natural liquefeito (GNL) são na maioria estruturas onshore, a construção destes terminais é custosa e muitos investimentos são necess
