The main objective of the presented study is the development of a predictive interval type-2 fuzzy inference system in order to estimate the mortality risk for a newborn, to be used as an auxiliary tool for decision making in medical centers where there is a lack of professionals for this purpose and, afterwards, to compare its performance to a type-1 fuzzy system. The input variables were chosen due to their acquisition ‘simplicity, not involving any invasive tests, such as blood tests or other specific tests. The variables are easily obtained in the first few minutes of life: birth weight, gestational age at delivery, 5-minute Apgar score and previous report of stillbirth. Databases from the DATASUS were used to validate the model. 1351 records from the city of São José dos Campos, a mid-sized city in the São Paulo state’s countryside, were considered in this study. Finally, an analysis using the ROC curve was performed to estimate the model’s accuracy

A doença de Charcot-Marie-Tooth (CMT) é a mais freqüente das neuropatias hereditárias, mas a sua história natural é pouco conhecida. Apesar da maioria dos pacientes apresentarem uma evolução com características mais “benignas”, é associado à doença com um comprometimento funcional, o que pode ser acompanhado de limitações e incapacitações. O presente estudo teve como objetivo avaliar a qualidade de vida de pacientes afetados pela CMT1A. Considerando que a qualidade de vida pode sofrer influência de variáveis sócio-culturais, um estudo neste contexto mostra-se oportuno. Nenhum estudo de nosso conhecimento realizou tal avaliação no contexto brasileiro. Fizeram parte deste estudo pacientes com CMT decorrente da duplicação 17p11.2-p12 (CMT1A) que foram avaliados quanto ao comprometimento funcional por meio da aplicação do SF-36. Esse questionário é utilizado internacionalmente para aferir a qualidade de vida dos indivíduos. Os resultados obtidos foram submetidos à análise estatística. Como resultados não se observaram associações entre o gênero e os domínios avaliados para a qualidade de vida. Os dados obtidos revelaram que a qualidade de vida dos pacientes com CMT1A se mostrou comprometida principalmente quanto aos seus Aspectos Sociais (p = 0,02) e Aspectos emocionais (p = 0,04). Adicionalmente, houve uma tendência ao comprometimento da Capacidade Funcional (p = 0,08), sendo que os outros índices de avaliação de comprometimento físico se mostraram preservados. A presença ou ausência de ocupação parece influenciar os Aspectos Sociais apresentando uma tendência de diferença significativa (p = 0,07), possuindo o grupo com ocupação valores superiores. Apesar da CMT1A apresentar piora clínica ao longo dos anos, a idade mais avançada não implicou em uma pior percepção da qualidade de vida no grupo de pacientes estudados no presente trabalho...

The steady increase in the price of oil and its derivatives, carbon credits, the concern with the environment combined with the precipitation of rain water and lack of water resources that Brazil has suffered in 2014 caused a migration of participation sources of energy in the Brazilian energy matrix. The hydropower sector suffered big drop at 2013 and is suffering so far, contributing thus to the generation and cogeneration of thermal energy using renewable energy sources such as: sugarcane bagasse, wood chips, rice husks, among others. The selling price of the electricity market reached the level of R$ 807, 00 MWh in January 2014 (Source: ANEEL), heating the Brazilian thermoelectric sector. Although thermoelectric use in bulk water as vaporizing fluid to produce electricity and use in various processes, water reuse plans have become an important factor in these industries. The increased use of biomass has been the bagasse which is allied to the sugarcane sector, strong market in Brazil, and consists basically use the rest of sugar cane, sugarcane industries that would play out. The sugar and ethanol industry is very unstable and only lasts for 6-8 months a year, and the remaining time in the period known as between crop that corresponds to the planting and harvesting of sugarcane and then enter the period of vintage which is the constant cane harvesting and crushing it. This instability of the market and the thermoelectric idle period leads the thermoelectric industries to seek other sources of renewable energy, such as wood chips (pine, Eucalyptus, Orange), rice husk, sorghum among others, to not be dependent on alcohol sector. The present work aims to study the use of wood chips as an alternative biomass for burning a fuel that essentially uses bagasse, the thermoelectric in question consists of two boilers that produce together 350 t / h ...

In this work was developed a fuzzy computational model type-2 predictive interval, using the software of the type-2 fuzzy MATLAB toolbox, the final idea is to estimate the number of hospitalizations of patients with respiratory diseases. The interest in the creation of this model is to assist in decision makeshift hospital environment, where there are no medical or professional equipment available to provide the care that the population need. It began working with the study of fuzzy logic, the fuzzy inference system and fuzzy toolbox. Through a real database provided by the Departamento de Informática do Sistema Único de Saúde (DATASUS) and Companhia de Tecnologia de Saneamento Básico (CETESB), was possible to start the model. The analyzed database is composed of the number of patients admitted with respiratory diseases a day for the public hospital in São José dos Campos, during the year 2009 and by factors such as PM10, SO2, wind and humidity. These factors were analyzed as input variables and, through these, is possible to get the number of admissions a day, which is the output variable of the model. For data analysis we used the fuzzy control method type-2 Mamdani. In the following steps the performance developed in this work was compared with the performance of the same model using fuzzy logic type-1. Finally, the validity of the models was estimated by the ROC curve

The main objective of the presented study is the design of a analog multiplier-divider as integrant part of the type-reducer circuit of type-2 fuzzy controller chip. The proposed circuit is a multiplier/divider which operates in current mode, in the CMOS technology with a supply voltage of 1.8 V.The circuit simulation was performed in PSPICE software with simulation model provided by AMS (Austria Mikro Systems International) in CMOS technology 0.35μm

Energy efficiency is an increasingly important issue due to the current scenario where increasing demand is growing faster than the energy supplied. It is important, therefore, analyze and minimize electrical system losses. This study conducts a comparison of a system formed by a photovoltaic generator feeding an LED lamp directly without steps DC-AC -DC conversion, and a system using these conversion steps for the same lamp power. Losses in conversion steps are quantified and the degradation of power quality occurred due to conversion is evaluated
