‣ Método de caracterização do escoamento bifásico usando sensores de deformação baseados em redes de Bragg em fibras ópticas

Baroncini, Virgínia Helena Varotto

Português
This study developed a technique to characterize the two phase flow using optical fiber Bragg grating strain sensors. These sensors have features such as small size, flexibility, allowing to accurately measure a number of parameters under adverse conditions. The sensor unit consists of optical fiber Bragg grating positioned transversely to the flow and fixed in the pipe walls. The hydrodynamic pressure applied by the liquid or air/liquid flow to the optical fiber induces deformation that can be detected by the optical fiber Bragg grating. Given that the applied pressure is directly related to the mass flow it is possible to establish a relationship using the grating resonance wavelength shift to determine the mass flow when the flow velocity is well known. For two phase flows of air and liquid there is a significant change in the force applied to fiber that is accounted for the very distinct densities of these substances. As a consequence the optical fiber deformation and the correspondent grating wavelength shift as function of the flow will be very different for an air bubble or a liquid slug allowing their detection as they flow through the pipe. Due to its versatility and multiplexing capabilities optical fiber Bragg gratings are particularly suitable for this application. The experiments were performed in a pilot plant using air-water two-phase flows...

Two-phase flow is present in many industrial applications, among them in petroleum industry as gas-liquid flow in pipelines. The knowledge of the phase distribution in the pipe flow is important for the efficiency and safety of the plants. In the academia, the knowledge of this phase distribution allows the understanding of physical phenomena, as well as gives support for the development, refinement and validation of physical models. In this work, a novel capacitive array sensor has been developed and its use was investigated to image two-phase flow. The measuring principle is based on the difference between electrical permittivity of the phases. Therefore the sensor can be applied to electrically non-conductive substances such as oil and organic liquids. Several simulations based on Finite Element Method have been performed to improve the sensor geometry and predict its electrical behavior. The sensor consists of two copper rings being one emitter and one receiver ring. Receiver ring is divided into segments which are individually interrogated by the measuring electronics in a fast and multiplexed manner. In this way, images are directly generated from acquired signals of electrodes, in a way that visually represents the investigated geometry avoiding the use of some image reconstruction technique. The sensor is fabricated in a flexible printed-circuit board which is flush- mounted inside the pipe wall. A measuring electronics is responsible to detect the capacitance changes in the electrodes. The introduced sensor along with the associated electronics has been tested in static and dynamic two-phase flow...

Português
Video quality assessment plays a key role in the video processing and communications applications. An ideal video quality metric shall ensure high correlation between the video distortion prediction and the perception of the Human Visual System. This work proposes the use of visual attention models with bottom-up approach based on saliencies for video qualitty assessment. Three objective metrics are proposed. The first method is a full reference metric based on the structural similarity. The second is a no reference metric based on a sigmoidal model with least squares solution using the Levenberg-Marquardt algorithm and extraction of spatial and temporal features. And, the third is analagous to the last one, but uses the characteristic Blockiness for detecting blocking distortions in the video. The bottom-up approach is used to obtain the salient maps, which are extracted using a multiscale background model based on motion detection. The experimental results show an increase of efficiency in the quality prediction of the proposed metrics using salient model in comparission to the same metrics not using these model, highlighting the no reference proposed metrics that had better results than metrics with reference to some categories of videos.; A avaliação de qualidade de vídeo possui um papel fundamental no processamento de vídeo e em aplicações de comunicação.

In this work a study applied in controlled boost rectifiers with high power factor is presented. A most widely used conventional control strategy is the instant average current control, this kind of control have a fast current loop and a slow voltage loop.The cutoff frequency of the voltage loop is low because the output voltage ripple must be twice the frequency of the input network, that need to exist to provide an input current with low harmonic distortion. These controllers feature a high overshoot and a slow transition during the transient load what leads a high voltage in the output capacitors. The developed technique is a digital controller that operate with a feedforward output power associated with one cycle control. This strategy provides better results in the load transient, reducing the overshoot and alloying a reduction of the output capacitor.; Neste trabalho é apresentado um estudo de controladores aplicados a retificadores boost pré reguladores de alto fator de potência. A estratégia convencional, mais utilizada, é o controle por valores médios instantâneos que apresenta uma malha de corrente rápida e uma malha de tensão lenta.

Acerola (Malpighia punicifolia L.), also known as Antilles Cherry, is a fruit that presents relevant nutritional properties, such as high content of vitamins and bioactive substances with biological activities. These substances help in the prevention and control of cardiovascular diseases, cancer, diabetic retinopathy, and vision disorders among other ailments. However, the acerola shows fragile structure and high respiratory activity, resulting in lower shelf life. Thus, it is technically important the formulation of derivatives which retain the nutritional properties and bioactive compounds of the fruit. In this context there are gelling agents, food additives, including citrus pectin, which are used to thicken and stabilize fluid foods, giving them in this way, its texture. Thus, the present work aimed at the technological utilization of Acerola in the development of vinegar cream through the slow process. Initially, an alcoholic fermented product was obtained in stirred tank bioreactor and, subsequently, acetic fermented products were obtained either in a grapia (Brazilian ash) vinegar barrel or in a bench bioreactor, for subsequent gelation.

Studies investigating historical cultivars of wheat are widely available and show significant annual gains in grain yield (GY) by many producing countries, while some report recent decrease in genetic progress. In this sense, the evaluation of the gains inherent to breeding programs appears as a measurement tool of efficiency and can help define future strategies. Thus, the first study of this dissertation aimed to measure the genetic progress for GY obtained in wheat breeding program of the Central Cooperative Agricultural Research (Coodetec) through the annual evaluation of lines on value of testing and use trials (VCU). We used data from 836 experiments, conducted in 40 locations in the 2004-2013 period. We used the REML/BLUP analysis to access the genotypic values, which were used to estimate the genetic progress by the similar method described by Vencovsky et al. (1986). The overall genetic progress of the breeding program was 61.59 kg ha-1 yr-1 (1.68% yr-1), however, was partially counterbalanced by negative environmental effects (-22.19 kg ha-1 yr-1; -0.58% year-1). The genetic progress by VCU region ranged from 31.38 kg ha-1 yr-1 (VCU 4) and 115.33 kg ha-1 yr-1 (VCU 1). In commercial cultivars released between 1998 and 2014...

This research aims to analyze the limits and possibilities of professional qualification for economic and social rehabilitation of prisoners, with reference to the Penal Colony Agroindustrial of Paraná. It builds on theoretical and methodological foundations of the Historical and Dialectical Materialism and uses as data collection tool semi-structured individual interviews conducted with seventeen imprisoned participants of educational and professional activities. The main results show that the socioeconomic profile of the prison population, characterized by low education, lack of professional qualification, and the occupation of precarious jobs, contributes to entry into the crime and hence incarceration. The second aspect was noted the contradictory nature of the arrest at his punitive and ressocializadora purpose, with the simultaneous goal punish and reinsert the condemned to society. Finally the qualification, widely understood as a social relation, articulating general education, professional and practical, reduce the short and streamlined courses, regardless of education and integration between general and vocational education, even taking into account the market demands. The evidence presented allow us to infer that vocational training programs are inefficient and ineffective in the economic and social rehabilitation of prisoners. Prison labor...
