13. REGIONALIZATION OF MAXIMUM AND MINIMUM FLOW IN THE TELES PIRES BASIN, BRAZIL
ABSTRACT In a watershed there is space and climate variability within its catchment area, causing changes in water qualitative and quantitative characteristics. Thus, the hydrological data collected from a specific basin may be extrapolated to neighboring basins with similar physical characteristics, using techniques of hydrological regionalization. This stu

14. Financial and Real Sector Leading Indicators of Recessions in Brazil Using Probabilistic Models
Analisamos a capacidade de diversas variáveis do setor financeiro e do setor real da economia para prever recessões no Brasil entre um e oito trimestres à frente. Estimamos modelos probabilísticos de recessão e os selecionamos com base em suas previsões fora da amostra, utilizando a função Receiver Operating Characteristic (ROC). Encontramos que a ca

15. Parental influence on children’s answers to an oral-health-related quality of life questionnaire
Abstract The aim of the study was to evaluate parental influence on children’s answers to an oral health-related quality of life (OHRQoL) questionnaire. A cross-sectional study was conducted with a non-probabilistic sample of 84 pairs of 5-year-olds and parents/guardians. The participants were selected from a primary family healthcare center in Campina Gra

16. Probabilistic analysis of stress intensity factor (SIF) and degree of bending (DoB) in axially loaded tubular K-joints of offshore structures
Abstract The stress intensity factor (SIF) and the degree of bending (DoB) are among the crucial parameters in evaluating the fatigue reliability of offshore tubular joints based on the fracture mechanics (FM) approach. The value of SIF is a function of the crack size, nominal stress, and two modifying coefficients known as the crack shape factor (Yc) and ge

17. Sequential sampling of Euschistus heros (Heteroptera: Pentatomidae) in soybean
Integrated pest management programs for soybean (Glycine max (L.) Merrill) must be based on efficient sampling plans for estimating the pest population. Based on the spatial distribution of the Neotropical brown stink bug Euschistus heros (Fabricius, 1794) found on soybean, it was possible to construct a sequential sampling plan for the survey of this insect

18. Analysis of applicability of Peleg model to the cooking-infusion of mackerel (Scomber japonicus) slices
Mass transfer kinetics in osmotic dehydration is usually modeled by Fick's law, empirical models and probabilistic models. The aim of this study was to determine the applicability of Peleg model to investigate the mass transfer during osmotic dehydration of mackerel (Scomber japonicus) slices at different temperatures. Osmotic dehydration was performed on ma

19. A comparison of abundance estimators for small mammal populations
A major difficulty in the application of probabilistic models to estimations of mammal abundance is obtaining a data set that meets all of the assumptions of the model. In this paper, we evaluated the concordance correlation among three population size estimators, the minimum number alive (MNA), jackknife and the model suggested by the selection algorithm in

20. 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

21. Modelagem estatística de extremos espaciais com base em processos max-stable aplicados a dados meteorológicos no estado do Paraná / Statistical modelling of spatial extremes based on max-stable processes applied to environmental data in the Parana State
The most mathematical models developed for rare events are based on probabilistic models for extremes. Although the tools for statistical modeling of univariate and multivariate extremes are well-developed, the extension of these tools to model spatial extremes data is currently a very active area of research. Modeling of maximum values under the spatial dom

22. Avaliação estatística do erro de modelos de resistência para elementos lineares de concreto armado da ABNT NBR 6118:2007 / Statistical evaluation of resistance modelling error for linear elements of concrete structures of ABNT NBR 6118:2007
In a design of structures, it should be considered the intrinsic uncertainties to the present variables in the structure and in the structural concept, such as intensity and action distribution, mechanic properties of the material, geometric parameters of the structure and structural analysis and calculus models. Thus, the structural safety can only be measu

24. Epidemiological changes and financial consequences of hypertension in Latin America: implications for the health system and patients in Mexico
The aim of this study was to assess the costs and financial consequences of epidemiological changes in hypertension in México. The cost evaluation method to estimate costs was based on instrumentation techniques. To estimate the epidemiological changes and expected cases of hypertension in 2010-2012, three probabilistic models were constructed according to
