‣ Sensor capacitivo inteligente para monitoramento de escoamentos bifásicos

Santos, Greg José dos
Fonte: Curitiba Publicador: Curitiba
Tipo: Dissertação de Mestrado
Português
Two-phase flow is frequently found in industrial activities, for instance in chemical reactors or during oil production and transport, where gas-liquid flow type is the most common. Such flow is characterized by the simultaneous passage of two immiscible fluids in a pipe. The fluids may assume various spatial distributions in a pipe, which are classified into flow regimes. In many cases, the type of flow determines the efficiency and safety of the processes or plants in which they occur. The objective of this work is to develop a smart sensor for real-time monitoring of two-phase flows. Here two important monitoring parameters were selected; the first is the gas void fraction and the second translational bubble velocities. To this aim, a capacitive probe was developed that exploits the difference in electrical permittivity of the phases. In addition, a previously developed electronics have been further developed to make it possible to measure two channels simultaneously and the firmware has been modified for performing the calculation of the two parameters directly in the embedded microcontroller. The response of the capacitive probe depends not only on the volume fraction of the phases, but it also depends on the way they are distributed inside the pipe. In order to account for this...

Nowadays, there is a concern of society regarding the impacts caused by the industries on the environment. Large amounts of water, wood and chemichal are used to produce cellulose and paper, and contaminated effluents are generated through the various industrial processes associated. The organic matter and the color of the Kraft effluent are due to the presence of lignin-derived molecules that are difficult to be removed or biodegraded. With intent to remediate this effluent, this study aim to evaluate the removal of color and residual organic matter from biologically pretreated Kraft effluent, using activated carbon from coconut shell and montmorillonite clay by adsorption method through experimental designs. For the color and organic matter removal, the following factors were evaluated: a) pH of the effluent; b) the mass of the adsorbent material in the adsorption process and c) temperature. The adsorption capacity of organic matter and color in the activated carbon and in the montmorillonite clay were determined by the mathematical model of Langmuir and Freundlich, by means of isotherm adsorption construction in Kraft effluent.The effluent was characterized by COD, DBO5,20, COT and true color before and after the tertiary treatment. For it treatment two temperatures were employed: 25 °C and 40 °C...

This work proposes the resolution of stochastic bending problem in a Euler- Bernoulli beam, on a foundation type Pasternak, through a computational method based on Monte Carlo simulation. Uncertainty is present in the elastic coefficients of the beam and foundation. First, it is established the mathematical formulation of the problem which is derived from a physical model displacement of the beam, that takes into account the influence of the foundation on the problem of response. This requires an approach that is made up on the most common models of foundation, which are: the model Winkler type and model of Pasternak.In sequence we study the existence and uniqueness of the variational problem. To obtain the solution of the problem, a mathematical reasoning is carried out, to the following matters: representation of uncertainty, Galerkin method, serial Neumann, and finally the lower and upper bounds. Finally, the performance of lower and upper bounds, derived from direct simulation of Monte Carlo were evaluated through various cases where the uncertainty lies in the different coefficients composing the equation bending as a variational problem. The method proved to be efficient, both in the response of the convergence point as regards the computational cost.; A presente dissertação propõe a resolução do problema de flexão estocástica em uma viga Euler-Bernoulli...

In this work is presented an intelligent optical sensor capable to localize the position of mechanical impacts on a flat surface structure. The transducers were previously characterized relatively to mechanical strain. In this application, four optical fiber Bragg gratings were installed on a polymethyl methacrylate square plate, subjected to a set of mechanical impacts under controlled conditions. The responses provided by the transducers were used to model and test Artificial Neural Networks. The system showed the capacity to determine the disturbance positions, even at impact points different from the ones used in the training stage. The higher mean square error obtained in the test stage was 1,1 cm relatively to the impact position, wherein the points were located at a distance of 5 cm from each other on a test surface with 60 cm length , 60 cm width and 6 mm height.; CAPES; CNPq; FINEP; Fundação Araucária; Neste trabalho apresenta-se um sistema ótico inteligente apto a localizar a posição de impactos mecânicos aplicados em uma estrutura plana.

This work presents an application of optical fiber sensors based on Bragg gratings encapsulated in polymeric composite resin with glass fiber reinforcement. Three commercial epoxy resins were evaluated. The main objective of the study is to characterize the composites and investigate the feasibility of embedding the optical fiber sensors based on Bragg gratings in epoxy composite. In the characterization of the samples tensile tests were performed to evaluate the residual stress after the curing process. The residual stress was investigated by mains of a FBG sensor embedded in the composite. Additionally, tests were conducted to evaluate the glass transition temperature by DSC technique. The values of the axial tensile and simple flexural stress were investigated using a universal testing machine. In addition, tests were performed for evaluating the composite behavior when subjected to a fixed load and variable temperature ranging from 20 °C to the temperature limit of the glass transition of the composite. The results show a high level of integration of the FBGs with the epoxy composite. One of the results is promising for applications in a high power generator and in hostile environments working at temperatures up to 127 °C.; ANEEL; FINEP; CAPES; CNPQ; Fundação Araucária; Neste trabalho é apresentada uma aplicação de sensores à fibra ótica baseados em redes de Bragg encapsulados em compósito de resina polimérica com reforço de fibra de vidro.

Downward slug flow in ducts of circular cross section is a frequently observed flow regime in oil and gas transportation lines. The onset of this kind of flow is due to instabilities generated by irregular pipe topography. Therefore, to understand the hydrodynamics of the slug flow is paramount in the design of crude oil production lines as well as in the project of equipment involved in oil and gas operations. The goal of this work is to experimentally analyze and characterize the two-phase gas-liquid intermittent downward flow in ducts with inclination angles of 0°, −4°, −7°, −10° and −13°. The analysis was performed at different gas-liquid volumetric flow rates for which the slug flow regime was observed. An existing experimental rig in the NUEM/UTFPR labs was used to collect data. A pair of wire-mesh sensors to evaluate the flow structure, thus obtaining void fraction temporal series was employed. From those series, statistical distributions for the characteristic parameters of such slug flows – namely the elongated bubble translational velocity, the unit cell frequency, the liquid slug and the elongated bubble lengths and the void fraction in the elongated bubble region – were obtained. The processed signals were analyzed so as to identify the relationship between the slug flow parameters...

Hydroerosive grinding process is used on nozzle injectors for diesel system in order to improve its performance by rounding the internal diameter of the injection channels through which flows the diesel for injection in the engine. The efficiency of hydroerosive grinding process is related to the conditions of the erosive fluid used in the process, for which viscosity has a major role for efficiency maintenance. Coupling between particles and fluid is affected by viscosity decrease along time, thus influencing material removal rate efficiency and causing productivity losses, once cycle time increases to achieve the specified material removal rate. In the present investigation, the process efficiency was evaluated during 160 hours using viscosity correction of the erosive fluid in order to keep viscosity close to its initial work condition. The root cause for viscosity decrease was also investigated through evaluation of possible contamination of the erosive media by lower viscosity fluids existing in the process. After 160 hours of process monitoring with viscosity adjustment, it was observed 8,8 % of viscosity reduction considering the first and the last samples, besides that the material removal rate efficiency decreased only 4,2 % over 20 % decrease observed in a previous study related to hydroerosive grinding process without particle replacement and viscosity adjustment. Contamination of the erosive fluid by measurement oil used in the previous station was responsible for 37...

Technological advances in recent years have led to a growth in the user base using communication networks, especially with multimedia services such as IPTV, video conferencing and VoIP. As these services require more resources and generate a great demand on the network infrastructure, each user must have their applications dealt with in accordance with certain priorities, to provide an acceptable level of service. Under this assumption, the communication networks for wireless broadband, based on the IEEE 802.16 standard, also known as WiMAX, can meet the various demands of end users, the need for access to data at all times and in any place and the connectivity efficient broadband, offering excellent tredeoff for the end user by enabling high data transmission capacity at a relatively low cost of deployment. The provision of quality services is a very important factor for the performance of communication networks for that, the scheduling mechanisms, admission control connections and traffic policing, must be present. However, the IEEE 802.16 standard specifies only policies of how these mechanisms should be implemented, but does not define how to implement them. This research aims to present a new architecture for uplink traffic, the WiMAX network base stations...

The large number of mobile devices increased the interest in low-power designs. Tools that allow the evaluation of alternative implementations give the designer actionable information to create energy-efficient designs. This paper presents a new power measurement platform able to compare the energy consumption of different algorithms implemented in software and in hardware. The proposed platform is able to measure the energy consumption of a specific process running in a general-purpose CPU with a standard operating system, and to compare the results with equivalent algorithms running in an FPGA. This allows the designer to choose the most energy-efficient software vs. hardware partitioning for a given application. Compared with the current state-of-the-art, the presented platform has four distinguishing features: (i) support for both software and hardware power measurements, (ii) measurement of individual code sections in the CPU, (iii) support for dynamic clock frequencies, and (iv) improvement of measurement precision. We also demonstrate how the developed platform has been used to analyze the energy consumption of network intrusion detection algorithms aimed at detecting probing attacks.; A popularização dos dispositivos móveis impulsionou a pesquisa e o desenvolvimento de soluções de baixo consumo. A evolução destas aplicações demanda ferramentas que permitam avaliar diferentes alternativas de implementação...

When a pregnant woman is submitted to breast radiotherapy, the fetus may be seriously affected by the peripheral dose. In order to verify that dose, a humanoid phantom, was irradiated at the left breast. The phantom is an adapted manikin, with some materials (densities close to water) inside and outside of it. The irradiation was done using a 6 MeV x-ray beam energy from a linear accelerator “Clinac 600C”. During the irradiation, a shield around the abdominal area of the manikin, consisting of blocks and slabs of lead was used. In addition, two types of filters were used: a physical, with 30o angulation, and an enhanced dynamic one. Through a cylindrical ionization chamber, positioned in the simulator ́s fetal region, it was found that, at the end of the breast treatment, the peripheral doses reach values between 3.90 and 48.67 cGy, when the physical wedge was used. With the application of the enhanced dynamic wedge, the values were between 1.75 and 13.78 cGy. According to the obtained data, the physical wedge can increase the peripheral dose due to the larger background radiation intensity and to the scattering caused by the attenuator material. In addition, the shielding couldn ́t block all the secondary radiation, which, according to the literature...

‣ Olhares em construção: modos de vida representados nas fotorreportagens de o cruzeiro

This research investigates how photography, present in photo reportages made by Jean Manzon and José Medeiros in the magazine O Cruzeiro, contributed to representation of urban ways of life in Brazil during the passage of the 1940s to 1950s. I seek to understand which concepts were highlighted through the production of these photographers in the period 1947-1951. Therefore, 11 reportages published during the chosen period were analyzed. Based on the Science and Technology Studies, I propose that the ways of seeing are essential components of photographic technological system. Because the private and collective ways of interpreting the world in which photographers and editors are embedded are crystallized in photos during production. The association of photography to the press, especially in the early twentieth century, expanded the access to representations of cities, people and lifestyles from places that many people would not be able to see with their own eyes. O Cruzeiro was a weekly illustrated magazine started in 1928. In the 1940s, inspired by European magazines, it became a modernization's vector of Brazilian photojournalism. With thematic variety and national distribution, O Cruzeiro reached a wide audience and became an important media in Brazil. I understand that photography influences the relationship between people and the world when the perception of objects...

Among the results it was found that, although membership of the cooperative has improved the social...

‣ Contribuição para o desenvolvimento de uma arquitetura de computação própria ao paradigma orientado a notificações

Linhares, Robson Ribeiro
Fonte: Curitiba Publicador: Curitiba
Tipo: Tese de Doutorado
Português
Current software development processes lack techniques for the productive and quality design of software that makes efficient use of the parallel execution capabilities provided by the hardware of the modern computing systems. In this context, the Notification Oriented Paradigm (NOP) has been recently developed. The essence of this paradigm is a new organization for software logic based on precise notifications among causal-logical entities. One of the main effects of this paradigm is to enable smaller coupling in the software structure. As a consequence, NOP allows the exploitation of parallelization and/or distribution in a simpler and more efficient way than more commonly used programming paradigms, such as the Imperative Paradigm and the Declarative Paradigm. However, the dynamics of execution under NOP, based on notifications, is not efficiently performed by the hardware of current computing systems, which are fundamentally based on the von Neumann/Turing (and similar) model of sequential execution. In order to address this drawback, this thesis presents a contribution to development of a computing architecture, named ARQPON, which is suitable for execution of software developed according to NOP computing model. ARQPON was designed based on principles of generality...

This work analyses the Brazilian federal government attempts to redefine the Public Educational System purposes, as a social institution, after the changes happened (international and national levels) in the productive, cultural and political sites, as a result of the economic globalization and the ideology of liberalism which are presented as a concrete reality in the contemporary scenery. This investigation focused the international context of the seventy and ninety decades of the twentieth century; the national environment related to the Brazilian educational curriculum reform; the process of the elaboration of the National curriculum parameters and the backgrounds in which the parameters are based. This research aimed to verify how the social changes influenced the redefinition of the goals of the public educational system. Besides this, it was examined which were the leading concerns linked to this redefinition and how these concerns defined the curriculum references. Through this research it was proved that the redefinition of the public educational system cannot be conveyed through a very restrict group of professional leaders. The community which gives academic and economic support to the public educational system must be involved in order to discuss the process of the redefinition. It was also verified that the accomplishment of the new curriculum proposal is linked to several significant issues that cannot be fulfilled only through the good will of the professionals who were in charge of the execution of the new parameters in the classrooms. The National Curriculum Parameters discourses are easily optimistic...

This research aims to analyze whether investments of Brazilian forestry companies, concerning activities that shape social responsibility, are reflected in the values of their shares. Its context is that of sustainable development or sustainability, that is, a social paradigm about the possibility of achieving economic development, within the logic of expansion and accumulation, without greatly compromising the natural resources for future generations. The relevance of this research lies in the importance of the topic in the present days, in seeking to assess a company beyond its financial and economic aspects and in to proposing indicators that relate such aspects with those of social responsibility. The present investigation was limited to Brazilian forestry companies, listed on the BM&FBOVESPA, in May of 2012. The social responsibility of these companies was described by the indicators proposed by the Global Reporting Initiative and covered the following aspects: environmental, human rights, labor practices and decent work, society, product liability and economic. Such description was restricted to the period of 2009 and 2010. The results showed that only five out of nine surveyed companies had prepared sustainability reports within the period aforementioned. For a society that wants to achieve sustainability this scenario is rather disturbing...

This work presents a method for automatic classification of faults and events related to quality of service in power distribution networks, based on oscillographies of the bar feeder voltages of the distribution substation. We present the results for two distinct pre-processing forms of the voltage signals. The first is based on the Fourier Transform and the second on the Wavelet Transform for different families of wavelet functions. We compared three neural models for the process of classification: Multi-Layer Perceptron, Radial Basis Function and Support Vector Machine. The models were trained taking into account the autonomous operation of networks, i.e. automatic model selection and control complexity. The results were validated for a set of simulations performed using the Alternative Transient Program, aimed at practical implementation of the proposed method in an oscillograph logger, developed by Lactec together with Copel, called the Power Quality Monitor. The results were obtained with performance on the order of 90% of average accuracy for the various pre-processing forms and neural models.; Este trabalho apresenta uma metodologia para classificação de eventos de curto-circuito e mano-bras em redes de distribuição de energia elétrica...

Tipo: Tese de Doutorado
Português
This thesis proposes a new methodology based on ontologies and artificial intelligence techniques to support the diagnosis and the teaching-learning process in neuropediatric physiotherapy. In this area, standardized and objective measurements to quantify the diagnosis are difficultly found. The diagnosis is limited to inform in which months of the normal motor development a patient can be classified, based upon only on the subjective experience of the physiotherapist. In this work formal methods for knowledge acquisition and representations were used. Possible divergences of opinions between experts were systematically treated, and the acquired knowledge was represented as an ontology. Such ontology generated a set of classification rules from which three different approaches for diagnosis were developed: a crisp expert system, a fuzzy system, and another approach based on deterministic models. The crisp expert system did not accomplish to the problem. The fuzzy approach was not adequate too. The last approach was shown to be adequate for classifying a given patient with different degrees of membership to several months of the motor development. Results using this methodology suggested that it is capable of simulating objectively the diagnosis from human experts when analyzing real-world cases...
