TRANSMISSION LINE MODEL
- JEREMIAS CORAL KLAUSNER
This thesis introduces a metodology for the simulation of transmission lines, power generators, interconnnections and loads, base don digital filtering models. These models make intensive use of digital equivalent network concepts in order to solve the computability problem of the digital filter. The result of this work is a system that represents the discrete-time signal on a bandwsiths covering up to the Nyquist frequency, in contraposition with traditional methods of computer simulation. The structure is easily implemented with Digital signal Processors (DSPs), resulting in real time simulations that compare to off-line circuit simulators in precision.

A COMPARISON ANALYSIS OF THE MAIN FORESTS COMBINING METHODS APPLYED TO THE INTERNATIONAL PETROL MARKET
- ALVARO EDUARDO DE FARIA JUNIOR
It is a fundamental principle of the Decision Analysis that the subjective forecasts used in na analysis should be based upon a synthesis of all the available evidence. Thus, when part of the decision-maker s evidence is in the form of a variety of forecasting models, or expert opinions. Decision Theory requires him to formulate a combination of these predictors. This work takes into account the Bayesian methodologies Outperformance and Quasi-Bayes, as well as the classical model of Optimal Combination, all applied to the combination of petroleum medium prices, generated by experts fo Petrobrás, for several international markets. It is...

Praticando o ensino da língua portuguesa culta: um relato de experiência.
- Niulza Antonietti Matthes
A linguagem é, ao mesmo tempo, o principal produto da cultura e o principal instrumento para sua transmissão. O uso da língua em uma sociedade como a nossa, em constante transformação e permeada por meios de comunicação cada vez mais dinâmicos e sofisticados, requer uma práticalingüística variada, consciente e adequada às diferentes situações comunicativas. Sendo a língua um elemento articulador de toda a aprendizagem, é imprescindível que a escola se torne um espaço de prática lingüística efetiva e que o ensino da língua materna objetive tornar o aluno umcontemporâneo de sua época, instrumentalizando-o para uma ampla participação social. É função...

Aspectos metodológicos del entrenamiento de la fuerza en el campo de la salud
- Jiménez Gutiérrez, Alfonso; Paz Fernández, Jose Antonio de; Aznar Laín, Susana
El entrenamiento de la fuerza muscular debe constituir necesariamente una parte importante de los programas de actividad física en el campo de la salud, especialmente si tenemos en cuenta las serias consecuencias que la ausencia de movimiento derivada del modelo de vida sedentario imperante produce en la reducción de la función muscular. Ahora bien, hasta la fecha las indicaciones y recomendaciones generales respecto a aspectos metodológicos como la organización y estructuración de las cargas, la intensidad, la recuperación, el volumen, la frecuencia de estimulación, etc., de este tipo de entrenamiento eran poco concretas y excesivamente genéricas en este campo. En...

La complementariedad del log-lineal y del análisis de correspondencias en la elaboración y el análisis de tipologías
- Borràs Catalá, Vicent Eduard; López, Pedro; Lozares Colina, Carlos
Los análisis que combinan diversos métodos y técnicas según los diferentes objetivos planteados son susceptibles de obtener subproductos que, teniendo un interés sólo indirecto o relativo dentro del planteamiento global, permiten también mejorar los métodos de análisis y encontrar formas combinadas para construir objetos que sean pertinentes para la investigación. Es el caso de este artículo. En la construcción de tipologías se han empleado, aparte de otros métodos, dos concretamente que se han mostrado eficaces para dicha finalidad: el log-linear y el análisis de correspondencias. Como resultado de dicho trabajo se ha analizado su complementariedad y sobre todo dónde radica...

Ni methodus, ni methodium; ¡methoidea!: el camino al conocimiento y sus obstáculos
- Andrade, Gabriel; Muñoz, Ángel
El siguiente escrito es una crítica a la rígida mentalidad que prevalece en las universidades, la cual
tiende a limitar la creatividad de la actividad intelectual, a favor del cumplimiento de una serie de criterios 'metodológicos', que a la larga, entorpece mucho más que conducen la investigación. La etimología latina revela que la separación entre camino (methodus) y cerco (methodeia) es muy corta, y que lo que inicialmente puede concebirse como un camino que guía la ciencia, fácilmente puede convertirse en el gran cerco que obstaculiza la actividad científica.

Profundización mínima necesaria para la evaluación de impactos de cultivos marinos sobre la fauna bentónica
- Garmendia, J.M.; Parada, J.M.; Murillo, J.; Mora, J.
The macrobenthos is an useful tool for studying the impact of marine fish farms on the nearby area. Sampling
macrobenthic fauna is both work- and time-intensive, so it is important to determine the minimum optimal
volume to be sampled.
For this purpose, the present study aimed to find the depth of samples needed to carry out an accurate monitoring
of a bottom affected by fish farms. Two different types of bottom (sandy and silty) were sampled in two
Galician rias (O Barqueiro and Vigo) in which there are fish farms. In the first 6 cm, we found 86.29 % of
the species richness and 84.75 %...

Hacienda Pública Vs. Economía Pública en el cambio de siglo
- Gimeno Ullastres, Juan Antonio
The so-called Public Economics seems to be slowly replacing the traditional name of Public Finance. Both of them deal with the science that studies the economic behaviour of the Public Sector and its effects over the economy. Is this change actually linked to relevant modifications in the scope of the research, in the methodology or in the dominant points of view? This paper tries to answer these questions, specifically through the analysis of the most important papers published in journals and launched in Congresses on the field. It will also underline the parallelism with the old change of designation from...

¿Qué teoría del comportamiento para las Ciencias Sociales?
- Boudon, Raymond
As the social sciences deal with macrophenomena caused by individual human actions, they have to use a theory of human behaviour. They basically use three types of theory: the rational-utilitarian theory, the causalist theory which sees behaviour as caused by social, cultural or biological forces and the "rational psychology" successfully explained in Nisbet's sense.
The three theories are important in the sense that they have shown their capacity to explain convincingly puzzling phenomena. Type I and II theories have been claimed to be potentially general. They are not since there are many familiar phenomena they are unable to explain. Type III...

Testigos y protagonistas: un proceso de construcción de conocimiento conjunto con vecinos Qom. Una forma de hacer investigación y extensión universitaria
- Tamagno, Liliana; García, Stella Mary; Ibáñez, Maria Amalia; García, María del Carmen; Maidana, Carolina; Alaniz, Marcela; Solari Paz, Verónica
The issue of this paper is to present what we define as knowledge produced along with the Toba people whom which we work with since 1986. That knowledge is the product of what we call a "dialogue with the field¿ -understanding the Toba people as valid speakers in the knowledge production- and a "dialogue with the academy¿ in the sense of breaking certain epistemological obstacles that -being produced in the academic field- donÊt allow us to go deeper in the comprehension of the sociocultural dynamics of the Toba people. In this process of knowledge construction, the research task and the...

Florestan Fernandes and the sociology like criticism of the social process
- Duarcides Ferreira Mariosa
Many errors in the use of the concept of critique could be prevented if the theoretical and methodological bases of the work of Florestan Fernandes are taken into account. Aiming to provide a better understanding of Fernandes s sociology, the research starts with a discussion of this concept applying it to his theoretical and empirical works as well as to the literature related to their reception. The conclusion is that the term critique can be applied to Fernandes s critical attitude in relation to both his object of knowledge and the method for the discipline of sociology.

Sequential effects in the lexical decision task: The role of the item-frequency of the previous trial
- Previous Trial,Manuel Perea,Departament De Metodologia
Two lexical decision experiments were conducted to determine whether there is a specific,
localized influence of the item-frequency of consecutive trials (i.e., first-order sequential
effects) when the trials are not related to each other. Both low-frequency words and
nonwords were influenced by the frequency of the precursor word (Experiment 1). In
contrast, high-frequency words showed little sensitivity to the frequency of the precursor
word (Experiment 2), although they showed longer reaction times for word trials preceded
by a nonword trial. The presence of sequential effects in the lexical decision task suggests
that participants shift their response criteria on a trial-by-trial basis.

In the lexical decision task, participants must...

In press. Acta Psychologica Does the proportion of associatively related pairs modulate the associative priming effect at very brief stimulus-onset asynchronies?
- Eva Rosa,Manuel Perea,Departament De Metodologia
A number of experiments have shown that the magnitude of the associative priming
effect increases substantially when there is a high proportion of associatively related
pairs in the list when the stimulus-onset asynchrony (SOA) between prime and target is
long (more than 400 ms). In the present series of experiments we manipulated the
proportion of associatively related pairs when the SOA was very brief (less than 200
ms). If processing of a target word is facilitated automatically by the prior presentation
of a related prime, the occurrence of priming should be unaffected by the proportion of
related pairs in the list. Experiment 1 showed a robust relatedness...
