Using Universal Line Model (ULM) for Representing Electromagnetic Transients in Three-Phase Transmission Lines

The second-order differential equations that describe the polyphase transmission line are difficult to solve due to the mutual coupling among them and the fact that the parameters are distributed along their length. A method for the analysis of polyphase systems is the technique that decouples their phases. Thus, a system that has n phases coupled can be represented by n decoupled single-phase systems which are mathematically identical to the original system. Once obtained the n-phase circuit, it's possible to calculate the voltages and currents at any point on the line using computational methods. The Universal Line Model (ULM) transforms the differential equations in the time domain to algebraic equations in the frequency domain, solve them and obtain the solution in the frequency domain using the inverse Laplace transform. This work will analyze the method of modal decomposition in a three-phase transmission line for the evaluation of voltages and currents of the line during the energizing process.

Apontamentos críticos para o tratamento da questão ambiental na perspectiva da emancipação

The belief in the existence of an ecological crisis that would affect the future of the planet, is one of the factors that causes the appearance of ecological concern, resulting in the adoption of non-predatory consumer practices and more respectful relationships with non-humans beings. This study starts from the assumption of the existence of an environmental question, and aims to investigate some of the cultural causes of human predation and identify possible ways in which environmental question can be treated critically to search overcomes. Follows the reasoning that western society as a complex of social relations, the capitalism, as a mode of production utilities and rational right, are all consequences of the modern rationality, cognitive and moral logic that transforms people and nature in satisfaction instruments of individual interests. However, despite being identified as the causative root of environmental question, modern rationality takes with it enough to promote the development of ecological respect, necessary in confronting and overcoming the environmental question, as it will be applied as a principle in redefinition of the relationship of human beings with themselves and with nature. And modern rationality can also make capitalism more efficient in the use and reuse of materials so as to consume fewer resources on the planet to satisfy human needs.

Reconhecimento de voz para aplicações em automação implementado em FPGA

In many movies of scientific fiction, machines were capable of speaking with humans. However mankind is still far away of getting those types of machines, like the famous character C3PO of Star Wars. During the last six decades the automatic speech recognition systems have been the target of many studies. Throughout these years many technics were developed to be used in applications of both software and hardware. There are many types of automatic speech recognition system, among which the one used in this work were the isolated word and independent of the speaker system, using Hidden Markov Models as the recognition system. The goals of this work is to project and synthesize the first two steps of the speech recognition system, the steps are: the speech signal acquisition and the pre-processing of the signal. Both steps were developed in a reprogrammable component named FPGA, using the VHDL hardware description language, owing to the high performance of this component and the flexibility of the language. In this work it is presented all the theory of digital signal processing, as Fast Fourier Transforms and digital filters and also all the theory of speech recognition using Hidden Markov Models and LPC processor. It is also presented all the results obtained for each one of the blocks synthesized e verified in hardware

O Mestre, de Ana Hatherly: uma insólita aprendizagem

O mestre (1963), written by the Portuguese author Ana Hatherly, continues to challenge our reading due to its disturbing nature. The text is not only connected to and transcends the emerging modernity of the Portuguese poetic avant- -garde experimental proposals of the period, presenting itself as a permanent intriguing text. This paper examines the narrative procedures put into action in order to destabilize the relationship I – the Other (master and apprentice), multiform agents, producers of metamorphosis and disturbing actions. The female narrator addresses love, truth, knowledge and power in an uncommon way and transforms the narrative into a magic practice, with surprising effects.
