Análise do comportamento em fadiga de rodas ferroviárias fabricadas pelos processos de forjamento e fundição

Since the beginning of the railway industry until today, rail wheels are important components to the good working of a railway. For being a critical security item, design and maintenance are done with extremely care to avoid failures. Despite de fact of railway components be projected to support a big number of cyclic solicitation during its life, some accidents still occur. These accidents, despite the low frequency, always have great consequences, drawing in great financial, material, and people losses. Nowadays, railway component failure is relatively low, because it’s been projected to work below the materials Fatigue Resistance Limit, however, with the growing demand of faster trains and higher load for each axle, the occurrence probability is even bigger. This work includes a comparative study of two fabrication processes (casting and forging) applied in the production of rail wheels where it was measured the mechanical properties of traction and fatigue. The study also verified through microstructural analysis, hardness, traction and fatigue tests, statistical analysis of fatigue test results and fractographic analysis that forging process lead to better correlations between fatigue life and mechanical properties, providing more security in railroads, less wagon retention caused by corrective maintenance and smaller operational cost with its use

Contagem automatizada de veículos utilizando segmentação estatística

In this work was developed a program capable of performing automatic counting of vehicles on roads. The problem of counting vehicles is using expensive techniques for its realization, techniques which often involve manual counting or degradation of the pavement. The main motivation for this work was the importance that the vehicle counting represents to the Traffic Engineer, being essential to analyze the performance of the roads, allowing to measure the need for installation of traffic lights, roundabouts, access ways, among other means capable of ensuring a continuous flow and safe for vehicles. The main objective of this work was to apply a statistical segmentation technique recently developed, based on a nonparametric linear regression model, to solve the segmentation problem of the program counter. The development program was based on the creation of three major modules, one for the segmentation, another for the tracking and another for the recognition. For the development of the segmentation module, it was applied a statistical technique combined with the segmentation by background difference, in order to optimize the process. The tracking module was developed based on the use of Kalman filters and application of simple concepts of analytical geometry. To develop the recognition module, it was used Fourier descriptors and a neural network multilayer perceptron, trained by backpropagation. Besides the development of the modules, it was also developed a control logic capable of performing the interconnection among the modules, mainly based on a data structure called state. The analysis of the results was applied to the program counter and its component modules, and the individual analysis served as a means to establish the par ameter values of techniques used. The find result was positive, since the statistical segmentation technique proved to be very useful and the developed program was able to count the vehicles belonging to the three goal..

Técnicas de análise multivariada com aplicações a dados de natureza biológica

A análise estatística multivariada, extensão da análise univariada, consiste num conjunto de técnicas estatísticas, aplicadas quando há diversas variáveis relacionadas simultaneamente, sendo todas elas, em princípio, consideradas importantes no fenômeno em estudo. É de grande aplicação a conjuntos de dados das mais diversas áreas do conhecimento, principalmente da área biológica. Seu desenvolvimento teve um grande impulso na primeira metade do século passado. Entretanto, devido a complexidade dos cálculos matemáticos, principalmente envolvendo operações com matrizes de altas ordens, as aplicações somente se popularizaram nos dias atuais, com o desenvolvimento dos computadores e aplicativos computacionais.

Análise da técnica dos estilos Crawl e Costas em praticantes de natação

The aim of this study was to analyze and evaluate the performance of swimmers tied to the Extension Project Natação na UNESP at distances of 25m, 50m, 75m and 100m. The study included 20 people, including 12 men and 8 women. From an aerial footage was possible to record the tests proposed by the analysis of videos of, Freestyleand Backstroke styles for stroke cycles, average speed, stroke frequency and time proof stretches of 0-25m, 25-50m, 50-75m e 75-100m. Thus, it was possible to calculate stroke length, frequency, average speed as proposed in the study of Maglischo (1999). From these data were applied to descriptive statistics with mean and standard deviation, minimum and maximum scores in the different parameters of analysis and statistical tests, t-test and correlation to make comparisons between styles and between the distances swims by the subjects. Regarding the performance of the participants in the eight proposed tests, it can be said that most have already mastered the styles Crawl and Back Crawl for having managed to finish the tests proposed. However, the results of the variables analyzed mainly by the total time obtained in the tests can classify the subjects in the initial phase of learning and to start the training will be necessary to improve the implementation of styles

Apoio comportamental positivo: estratégias educacionais aplicadas a comportamentos-problema de alunos

This study, based on the model of Positive Behavior Support, aims to identify how 40 primary school directors describe the process of development, application, and evaluation of educational strategies for pupils with behavioral problems. The results from a questionnaire indicated that 77.5% of the directors had pupils with behavioral problems. The most commonly used educational strategies of intervention were to speak with the child (13.3%) or with the parents (13.3%). The most common action for evaluation was observation of the child (27.6%). In general, the study verified that the strategies were employed informally and unsystematically. These findings indicate that research about the inclusion of children with behavioral problems is needed and challenge to rethink about the educators professional training.
