1. A numerical investigation into ultimate strength and buckling behavior of locally corroded steel tubular members
This paper presents the results of anumerical investigation into ultimate strength of locally corroded tubular member sunder axial compressive loads. A parametric finite element approach was used in order to simulatestructuralbehavior of damaged members. The results were then examined against an available experimental test. Validated models were used to deri

2. Modelagem e anÃlise de fatores influentes na gravidez na adolescÃncia na microrregiÃo de Campo Belo-MG / Modeling and analysis of factors influencing adolescent pregnancy in the micro region of Campo Belo-MG
The adolescence is a transitional period that occurs between childhood and adulthood which multifaceted nature cannot be measured, at the same time, by any definition alone. According to the World Health Organization, it is âan evolutionary stage characterized by a rapid biological (i.e. pubertal), social and psychological development, which occurs in betwe

3. Contribuição para a análise de teletráfego com dependência de longa duração. / Contribution to the analysis of network traffic with long-range dependence.
The use of network trac models that hold self-similar and long-range dependence characteristics have shown to be a key element on the correct characterization of Local Area Network (LAN) and Wide Area Network (WAN) network trac [1, 2]. Such characterization is necessary to monitor and control the network trac in converged networks [3]. In this context, the a

4. Effect of air pollution on diabetes and cardiovascular diseases in São Paulo, Brazil
Type 2 diabetes increases the risk of cardiovascular mortality and these patients, even without previous myocardial infarction, run the risk of fatal coronary heart disease similar to non-diabetic patients surviving myocardial infarction. There is evidence showing that particulate matter air pollution is associated with increases in cardiopulmonary morbidity

5. Avaliação contingente de serviços de saneamento básico em Palmas-TO / Contingent valuation of services of basic santation in Palmas- TO
The services of basic sanitation have crucial importance in relation to population welfare because the absence of this kind of services contribute negatively to population healthy, environment and have some impacts on the government budget. The main aim of this thesis is to estimate the willingness to pay relative to the improvement of basic sanitation (WTP)

6. O Impacto das Práticas ITIL na Flexibilidade Organizacional ¿ Evidências Empíricas em uma Empresa Multinacional de TI
The present work has as main objective the identification and impact analysis for the practice ITIL in the organizational flexibility of a multinational IT company, being this study of quali-quantitative and exploratory nature. To achieve this objective, some theoretical studies on bureaucracy, organization flexibility, control, IT governance and ITIL were d

7. Desenvolvimento de um modelo matematico mais rigoroso para polimerização radicalar controlada mediada por radicais nitroxido de estireno / Development of more detailed mathematics model for nitroxide mediated living free radical polymerization (NMRP)
Living Free-Radical Polymerization (LFRP) has been target of much attention in the last years, because it allows getting polymers with a highly controlled microstructure, with narrow distribution of the average molecular weights and polydispersity (PDI) close to unit, and with complex molecular structures (e.g. pure block copolymers), with different architec

8. A semi-parametric methodology to IBNR (Incurred But Not Reported) / Uma metodologia semi-parametrica para IBNR (Incurred But Not Reported)
We compare several forecast techniques for IBNR(Incurred But Not Reported) from a Run-Off triangle data, since the most simple techniques like Chain-Ladder and Separation Technique, to the more complex using Log-Normal models and Compound Poisson distribution. Therefore, exist the necessity of the use of Nonparametric techniques, using a model that consider

9. Análise do comportamento estrutural de ligações parafusadas viga-pilar com chapa de topo estendida / Analysis of the structural behavior of bolted beam-column extended end plate connections
This work presents a numerical and experimental analysis on the structural behavior of bolted beam-column extended end plate connections. The behavior of the end plate and bolts used in the calculations of the end plate strength is specially discussed. Numerical results are used as basis to the discussions presented in this work and the modeling methodology,

10. Analysis of the pattern of heart rate response by the time series and semiparametric methods and of its variability in the determination of the anaerobic threshold. / Análises do padrão de resposta da freqüência cardíaca pelos métodos de séries temporais e semiparamétrico e de sua variabilidade na determinação do limiar de anaerobiose
The objectives of the present study were to assess the heart rate (HR) response and its variability under resting conditions and during dynamic physical exercise, to determine the anaerobic threshold from the analysis of the HR responses during physical exercise using the autoregressive-integrated-moving average (ARIMA) and semi-parametric (SMP) mathematical

11. OTIMIZAÇÃO DE FORMA DE MODELOS BIDIMENSIONAIS DE ELEMENTOS FINITOS COM COMPORTAMENTO ELASTO-PLÁSTICO / OPTIMIZACIÓN DE FORMA DE MODELOS BIDIMENSIONALES DE ELEMENTOS FINITOS CON COMPORTAMIENTO ELÁSTICO-PLÁSTICO / SHAPE OPTIMIZATION OF 2D FINITE ELEMENT MODELS CONSIDERING ELASTO-PLASTIC BEHAVIOUR
The main goal of this work is to present an integrated system for the optimization of plane structures with elastoplastic behavior. The methodology proposes an alternative for the conservative way in which structures traditionally have been optimized, i.e., that they present linear elastic behavior. The computational system is said to be integrated because i

12. Normalization and analysis of DNA microarray data by self-consistency and local regression
A robust semi-parametric normalization technique has been developed, based on the assumption that the large majority of genes will not have their relative expression levels changed from one treatment group to the next, and on the assumption that departures of the response from linearity are small and slowly varying. The method was tested using data simulated
