Extração e Representação de Conhecimento de Séries Temporais de Demanda de Energia Elétrica Usando TSKR

The opening of the Brazilian market of electricity and competitiveness between companies in the energy sector make the search for useful information and tools that will assist in decision making activities, increase by the concessionaires. An important source of knowledge for these utilities is the time series of energy demand. The identification of behavior patterns and description of events become important for the planning execution, seeking improvements in service quality and financial benefits. This dissertation presents a methodology based on mining and representation tools of time series, in order to extract knowledge that relate series of electricity demand in various substations connected of a electric utility. The method exploits the relationship of duration, coincidence and partial order of events in multi-dimensionals time series. To represent the knowledge is used the language proposed by Mörchen (2005) called Time Series Knowledge Representation (TSKR). We conducted a case study using time series of energy demand of 8 substations interconnected by a ring system, which feeds the metropolitan area of Goiânia-GO, provided by CELG (Companhia Energética de Goiás), responsible for the service of power distribution in the state of Goiás (Brazil). Using the proposed methodology were extracted three levels of knowledge that describe the behavior of the system studied, representing clearly the system dynamics, becoming a tool to assist planning activities

Forró eletrônico: uma análise sobre a representação da figura feminina

Understanding music as a social manifestation, able to represent the time and culture along with their uses and mores, we look at the female figure in the electronic forró genre. Through a reading of the two genres musical and feminine we seek to identify the discourses present in the compositions, which refer to the feminine with thematic and/or terms referring to women. The study focuses on the compositions between 2009 to 2010 which became hits, ie.: those which have attained the highest number of listeners to 96 FM in a program named Paradão 96, broadcasted daily in the city of Natal/RN. Grounded in such concepts as cultural industry, mass culture, folkcommunication and gender, we analyze the processes of meaning production as a result of using the female figure and more accurately, about the representation of women through the discourse of this specific genre. We have chose the descriptive research with a qualitative approach and Discourse Analysis as a technique to identify the terms that refer to women, reflecting on what would be the possible meanings found in these speeches. We point out that in our investigation the female figure turned into a sexual object, erotic and submissive, in their turn, attributes usually given to women, was not a predominant result in the speech of electronic forró gender. With a variant thematic some playful and others about the betrayal of women we have identified that, to the surprise of many, including ourselves, romantic love was the one who led the audience requests during our time frame and that the female figure has several facets within the studied genre

A Representação discursiva da figura feminina no jornal O Porvir (Currais Novos/Rio Grande do Norte - 1926-1929)

The objective of this paper is to analyze how the female figure was portrayed in discursive narratives in the bi-weekly newspaper O PORVIR , which circulated in Currais Novos, in the state of Rio Grande do Norte, Brazil, between May 2, 1926 and January 20, 1929. Our analysis was based on the semantics of the text, by applying one of the primary concepts used in Textual Analysis of Speeches, Discursive Representation (ADAM, 2011; RODRIGUES; PASSEGGI; SILVA NETO, 2010). Textual Analysis of Speeches has its roots in Textual Linguistics and consists of a theoretical and descriptive approach (ADAM, 2011). This research is characterized as documentary (SEVERINO, 2007) and its corpus includes a review of 39 editions of the aforementioned newspaper, of which we extracted 292 articles that dealt with the female figure and 396 statements for analysis. We used the following semantic categories: referencing (CASTILHO, 2010; NEVES, 2007; KOCH; MARCUSCHI, 1998; MARCUSCHI, 2008; KOCH, 2009); predication (NEVES, 2007; RODRIGUES; PASSEGGI; SILVA NETO, 2010); modification (ADAM, 2011); and spacial and temporal localization (RODRIGUES; PASSEGGI; SILVA NETO, 2010). Our analysis revealed that lady, mother, wife and homemaker were most represented, and always combined with questions about motherhood, marriage and devotion to the home. Such representation does not diverge from pre-colonial models in the early twentieth century, which served as a standard for the female figure

Produção em revista : Representação do moderno e do regional na experiência potiguar anos 1920

This work brings some reading about a few Norte-rio-grandenses writers collaborations published in literary papers which circulated during the third decade of the twentieth century in Brazil, in a way of enlarging the understanding of how the cultural debate was carried out in the years of the definition of the Brazilian Modernism, based on the relationships between literature and culture. Under the genres of prose and poetry, the selected textual collaborations for analysis have brought the traces of a small group of articulated authors in the Brazilian cultural scenery from the 1920 s, concerning the issues of the modern (linked to the modernist renovation) and the regional (under the aspects of the tradition). The set of the analyzed collaborations is representative of a modern-regional cultural practice marked by a tendency either local or cosmopolitan, thus, sharing a large dimension of the formation of the modern literary tradition, marked by different kinds of practices which give form to the project of a collective national awareness. The characterization of the existence of an intellectual field with big links, however with its own characteristics and a certain autonomy, which also gets integrated to the cultural debate of the so-called modernist years through the literary vehicles, gives to these intellectual people a co-participation in the renewing movement in the formation context of the brazilian cultural modernity of the early twentieth century

Forró eletrônico: uma análise sobre a representação da figura feminina

Entendiendo la música como una manifestación social, capaz de representar el tiempo y la cultura, junto con sus usos y costumbres, dirigimos nuestra mirada en la figura femenina presente en el género forró electrónico. A través de la lectura de los dos géneros musical y femenino buscamos identificar los discursos, presentes en las composiciones, que se refieren a lo femenino con temática y/o términos que se refieren a las mujeres. El estudio se centra en las composiciones en el período 2009 a 2010 y que se convirtieron en éxitos, es decir, aquellos que han alcanzado el mayor número de oyentes de Radio 96 FM a través del programa Paradão 96, transmitido diariamente en la ciudad de Natal/RN. Basado en conceptos tales como industria cultural, cultura de masas, folkcomunicación y género, se analizan los procesos de producción de sentido como resultado del uso de la figura femenina y con mayor precisión, sobre la representación de las mujeres a través de discursos del forró electrónico. Elegimos el enfoque descriptivo cualitativo y análisis del discurso como una técnica para identificarlos términos que se refieren a las mujeres, reflexionando sobre los posibles significados que se encuentran en estos discursos. Se señala que en nuestra investigación no predominó una figura femenina convertida en un objeto sexual, erótico y sumisa, atributos dados para las mujeres, en los discursos de forró electrónico. Con variaciones en las temáticas algunas juguetones y otras acerca de la traición de la mujer identificamos que, para sorpresa de muchos, incluidos nosotros, el amor romántico fue el que llevó las solicitudes de audiencia durante nuestro período de tiempo y que la figura femenina tiene varias facetas dentro del forró electrónico

Liberdade e negação da vontade: análise do ser-livre como representação e na angústia

Common understanding about what freedom means has always been more or less related to the power to realize something intended, desired, a capability. Therefore, being free is commonly interpreted under the concept of free-will and the category of possibility to act. Although there are predecessors in History of Philosophy, Schopenhauer refuses the thesis of free will proposing otherwise the denial of willing (to live) as the ultimate possibility for human freedom, if not the only one left. The thesis that would make him famous was deeply misunderstood and so miscarried somewhat due to the way it was many times presented by the means of exotic examples wrapped in a mystical mood besides exaltations to Eastern traditions, which may satisfy anthropological curiosity instead of being capable to satisfy the reader in a philosophical way. It seems to result from Schopenhauer s thought a kind of pessimism against life. Otherwise, typical readings on the Schopenhauerian thesis are found full of inconsistencies once closely regarded, which blame does not belong to the author but to his interpreters. A new reading about the denial of willing as the ultimate possibility for human freedom demands a criticism on the inconsistencies and prejudgments deep grounded. For this, we firstly clarify the ways of understanding the willing nothing , which cannot be reduced to the mere refusal or conformism, being instead positively understood as a special manner of willing: the admission of oneself for the sake of one is. A few more than a century later The world as will and representation came to light, Heidegger proposes in his fundamental ontology that the proper being-free concerns to originary decision by which, in anguish of being suspended in nothingness, Dasein renders itself singular as the being who is in-a-world and to-death, concluding that the ultimate possibility of freedom is being-free-to-death. Developing the hypothesis that freedom, properly understood, concerns to nothingness as to indeterminate possibilities, we seek for a dialogue between Schopenhauer s thought and existential philosophy aiming to reconstitute and overcome Metaphysics tradition turning the question about freedom into a matter of Ontology. From the factual existence perspective, as we must show, every human activity (or inactivity) is ordinarily mediated by representations, in which me and world appear as distinct entities. So, each one among determininate individuals finds itself connected to the things in the world by interest, which proper concept must be sufficiently explored. Starting from this point, we may proceed to detailed analysis of usual representations of freedom aiming their destruction by Ontology and then reaching existential thesis according to Kierkegaard and Heidegger. Turning back to the analysis of Schopenhauer s work, we conclude existential understanding of freedom as will-to-be can also be found in Schopenhauer. In this way, denial of willing means ultimate freedom once the Will turns back to its own essence by suppressing the world as representation, which means the originary absolute indetermination of the extreme possibility to-be

O reino encantado do sertão: uma crítica da produção e do fechamento da representação do sertão no romance de Ariano Suassuna

Based on the relation history, literature and space, this work examines the production and the closing of the representation of the hinterland in the Romance d A Pedra do Reino of the paraiban writer Ariano Suassuna. Inspired by method proposed by deconstructionist by Jacques Derrida, our reflection decomposes the writing scene of Suassuna by means of it s tracks to interpret the operation of the representation of the space-hinterland for the speech of the writer. Being thus, we present the elements chosen for Suassuna to weave an identification it s with this space-hinterland, taking a priori as a sentimental place and of familiar origin . The construction of this relation of belonging in great is measured grounded for a familiar memory entangled in the context politician who culminated in the Revolution of 1930 and that he resulted for the writer in the death of father. Suassuna launches a look on the identity and the Brazilian culture that guided in the tradition concept it searchs to deny the gift grounding its speech in the return to the past, a past order . Specifically in it s romance we notice to exist the fusing of these tracks in the production of a representation of the hinterland that it intends to close a concept of this space and its culture. Soon, the idea of kingdom sends to the space of the enchantments manufactured in infancy and retaken by the intellectual radical who in the anxiety of honor the father figure, does not save efforts in constructing a space representation that, over all, either faithful the representation that it searchs to trace of proper itself. Under one it marks of universality , the hinterland-kingdom of Suassuna if discloses eurocentric in the measure where it perpetuates discurse the filiation of the European cultural traditions.

Da Pena à Espada: Xenofonte e a Representação de Esparta em A Constituição dos Lacedemônios

We intend to analyze how, through your own views and social practices, Xenophon composed the image of Spartans and their poliad regime during the period following the end of the 5th century to the early 4th century before BCE a time of great political turbulence in the Hellenic Poleis. In order to do so, we will use the writings in The Constitution of the Lacedaemonians, to point three elements that we believe are essential understanding of the Xenophon´s narrative: who was Xenophon and in which ways his life experiences influenced his narrative style; the idea of City, i.e., Xenophon´s idea of the Polis and how he defined it as a community of Citizens; and finally, to establish through which tools Xenophon build an image of Sparta and Spartans by way of their representations in his writings

A representação da mulher e as questões de gênero na toponímia urbana de Caicó-RN

This piece wants to investigate the relations between gender identities and the toponymy in Caicó city. To do so, we will discuss the reason why places are named, the practice of naming places, so as the process of choosing the names of neighborhoods, streets and city public squares. Thereby, we will investigate the space changes in Caicó city since its formation, as a village, until the decade of 1970. This period of time was chosen in order to discuss the toponymic process of the city, besides having noticed that public places and locations in Caico with the feminine nominations only appear from the second half of the 60s decade and in the beginning of the 70s. This way, we preferred to investigate who were the first Caicó women to have their names in the urban space; why women only begin to have homage from the decade of the 60s on; what is the importance and the location of the places with feminine names; and what gender image is there on this homage

Redes neurais e representação mental: um ensaio sobre harmonia e racionalidade

Investigaremos, a partir da perspectiva da Ciência Cognitiva, a noção de representação mental, no domínio da percepção visual humana. Ênfase é dada ao paradigma Conexionista, ou de Redes Neurais, de acordo com o qual tais representações mentais são descritas como estruturas emergentes da interação entre sistemas de processamento de informação que se auto-organizam - tais como o cérebro - e a luz estruturada no meio ambiente. Sugerimos que essa noção de representação mental indica uma solução para uma antiga polêmica, entre Representacionalistas e Eliminativistas, acerca da existência de representações mentais no sistema perceptual humano.

Em direção a uma representação para equações algébricas :uma lógica equacional local

The intervalar arithmetic well-known as arithmetic of Moore, doesn't possess the same properties of the real numbers, and for this reason, it is confronted with a problem of operative nature, when we want to solve intervalar equations as extension of real equations by the usual equality and of the intervalar arithmetic, for this not to possess the inverse addictive, as well as, the property of the distributivity of the multiplication for the sum doesn t be valid for any triplet of intervals. The lack of those properties disables the use of equacional logic, so much for the resolution of an intervalar equation using the same, as for a representation of a real equation, and still, for the algebraic verification of properties of a computational system, whose data are real numbers represented by intervals. However, with the notion of order of information and of approach on intervals, introduced by Acióly[6] in 1991, the idea of an intervalar equation appears to represent a real equation satisfactorily, since the terms of the intervalar equation carry the information about the solution of the real equation. In 1999, Santiago proposed the notion of simple equality and, later on, local equality for intervals [8] and [33]. Based on that idea, this dissertation extends Santiago's local groups for local algebras, following the idea of Σ-algebras according to (Hennessy[31], 1988) and (Santiago[7], 1995). One of the contributions of this dissertation, is the theorem 5.1.3.2 that it guarantees that, when deducing a local Σ-equation E t t in the proposed system SDedLoc(E), the interpretations of t and t' will be locally the same in any local Σ-algebra that satisfies the group of fixed equations local E, whenever t and t have meaning in A. This assures to a kind of safety between the local equacional logic and the local algebras

X-ARM: um modelo de representação de artefatos de software

A great challenge of the Component Based Development is the creation of mechanisms to facilitate the finding of reusable assets that fulfill the requirements of a particular system under development. In this sense, some component repositories have been proposed in order to answer such a need. However, repositories need to represent the asset characteristics that can be taken into account by the consumers when choosing the more adequate assets for their needs. In such a context, the literature presents some models proposed to describe the asset characteristics, such as identification, classification, non-functional requirements, usage and deployment information and component interfaces. Nevertheless, the set of characteristics represented by those models is insufficient to describe information used before, during and after the asset acquisition. This information refers to negotiation, certification, change history, adopted development process, events, exceptions and so on. In order to overcome this gap, this work proposes an XML-based model to represent several characteristics, of different asset types, that may be employed in the component-based development. Besides representing metadata used by consumers, useful for asset discovering, acquisition and usage, this model, called X-ARM, also focus on helping asset developers activities. Since the proposed model represents an expressive amount of information, this work also presents a tool called X-Packager, developed with the goal of helping asset description with X-ARM
