Compressão de Imagens Usando a Função de Peano e a Transformada Wavelet 1D

In this work, spoke about the importance of image compression for the industry, it is known that processing and image storage is always a challenge in petrobrás to optimize the storage time and store a maximum number of images and data. We present an interactive system for processing and storing images in the wavelet domain and an interface for digital image processing. The proposal is based on the Peano function and wavelet transform in 1D. The storage system aims to optimize the computational space, both for storage and for transmission of images. Being necessary to the application of the Peano function to linearize the images and the 1D wavelet transform to decompose it. These applications allow you to extract relevant information for the storage of an image with a lower computational cost and with a very small margin of error when comparing the images, original and processed, ie, there is little loss of quality when applying the processing system presented . The results obtained from the information extracted from the images are displayed in a graphical interface. It is through the graphical user interface that the user uses the files to view and analyze the results of the programs directly on the computer screen without the worry of dealing with the source code. The graphical user interface, programs for image processing via Peano Function and Wavelet Transform 1D, were developed in Java language, allowing a direct exchange of information between them and the user

Albuns fotográficos de/por Enoque Neves: uma poética visual

La imagen fotográfica la imagen despierta pulsiones, en una experiencia provocativa que acciona el campo mítico-fenomenológico descíframe o te devoro . El texto fotográfico no constituye sólo un momento del real , es mucho más que un recorte gélido del tiempo pasado. Sobretodo, porque la comprensión del lenguaje subyacente a la imagen fotográfica se coloca dentro y más allá de lo meramente dado y/o objetivado . En la comprensión de la imagen se disponen regímenes de subjetivación horadado por códigos culturales, dominios del lenguaje, símbolos, experiencias estéticas, creación simbólica, valores, memorias, imaginarios. En ese sentido, surge el estudio, el levantamiento y la sistematización del acervo fotográfico dejado por el fotógrafo autodidacta: Enoque Pereira das Neves (1918-2002), que produjo formas visuales reveladoras de orientaciones culturales colectivas y universos fotográficos imaginarios. Él fotografió por medio siglo la vida cotidiana del campesino, en tierras potiguares y paraibanas. En la comprensión del acervo opte por subdividirlo en álbumes los cuales revelan las intimidades del fotógrafo con el lugar, una escrita de si, un estado del alma, del sujeto que observa la relación sociedad y naturaleza, en una especie de simbiosis en que accionan potencias resonantes de creación en el devaneo de la materia, sobresaliéndose a la pulsión terrestre, o enraizamiento, os rizomas del hombre unido a la tierra, las tradiciones, a rusticidad, laboral, bien como el apelo estético direccionado al agua: pulsión de vida en tierras áridas. La comprensión del inmenso acervo, evaluado en más de cincuenta mil fotografías es profundamente representativa de predilección temática circunstanciada por la niñez, la narrativa enfoca imágenes míticas como la del Eros nudo, la madona y el niño, y prácticas culturales del universo infantil, como el juguete y el juego. Mismo el acervo siendo un apelo estético a la vida surgió la imagen fotográfica de la muerte, especialmente, la muerte en la niñez o ángel y la muerte de ancianos como o deseo de la última imagen de aquel entre los suyos. La investigación es transversal por los siguientes objetivos: propongo un reconocimiento del acervo de Enoque Pereira das Neves en la intención de comprender el universo imaginario presente en su obra fotográfica. Invisto también, en la posibilidad de hacer la lectura del acervo como álbum imaginario.

Mediação como instrumento de desjudicialização das questões familiares: constitucionalização do Direito de Família

The Liberal Constitutionalism emerged from the late eighteenth century, a period of major revolutions (French and American), fruit of the struggle for libertarian rights. Although the time of the first written constitutions, these were linked to mere political letters, did not provide for fundamental human rights, as it is, so only on the state organization, structure of powers, division of powers of the state and some relations between state and individuals. There was a clear division between the civil codes and constitutions, those governing private relations and acted as barriers to non-state intervention. After the Second World War, the constitutions are no longer Letters political order to establish how the human person, in order to enshrine the fundamental rights, the primacy of constitutional principles and take their normative function against ordinary legislator. Constitutional evolution gave the name of contemporary constitutionalism, based on repersonalization or despatrimonialização of Private Law, ceasing the separation of legislative civil codes and constitutions, in favor of the protection of fundamental rights of the human person. And this tendency to the Brazilian Federal Constitution of 1988 brought higher ground the dignity of the human person, the epicenter axiological legal to govern private relations, including family law. The constitutionalization of family law motivates the adoption of desjudicialização family issues, so as to respect the direio intimacy, privacy, private autonomy and access to justice. Conflictual family relationships require special treatment, given the diversity and dynamism of their new compositions. The break in the family relationship is guided in varied feelings among its members in order to hinder an end harmonic. Thus, the judiciary, through performances impositive, not to honor the power of decision of the parties, as also on the structural problems faced to operate on these cases, the environment is not the most appropriate to offer answers to the end of family quarrels. Situation that causes future demands on the dissatisfaction of the parties with the result. Before the development of the Family Law comes the need to adopt legal institutions, which monitor the socio-cultural, and that promote an effective assistance to people involved in this kind of conflict. In obedience to the private autonomy, before manifestations of volunteers involved in family mediation, among autocompositivos instruments of conflict resolution, is indicated as the most shaped the treatment of family quarrels. Remaining, then the state a minimal intervention to prevent excessive intrusion into private life and personal privacy

Corporeidade e educação: sinfonia de saberes na educação musical

This study investigates the implications between the musical theory and pedagogical practice based on a study that questions the reasons why some students feel incapable of learning the music language, as well as, if the musical codes are truly so difficult to be apprehended by them. To answer these questions takes itself as reference, the classes I have minister while teaching the disciplines: Music Workshop and Music Language I in the Art Department, Scenic Art Course at the Federal University of Rio Grande do Norte. I have searched the knowledge that constitutes the teacher formation based on the union between the pedagogical efficiency and sensibility, searching in the Corporality the theoretical port for my investigation. This way, advocating is a methodological principle for musical education originated from the experience of knowledge: creating, playing, feeling, thinking, and the interaction among them, conducting the students not only to music learning, but to a process of human formation. It adopts itself as methodological resource, amongst the qualitative methods, some of the techniques that are associated with the ethnographic research, for having as its main objective, to study the meaning of the actions and events of the investigated group. The analysis of the data leads to the conclusion that when the teacher displays his or her pedagogical knowledge in an environment constructed with affectivity, in a playful and pleasant form, the assimilation and construction of the musical concepts happen naturally and efficiently, surpassing the taboo that music learning is only possible to the especially well endowed people for music. Very aware that the scientific debate is important for the strengthening of formative programs involved in the growth and consolidation of the musical teaching and learning area, it is expected to promote this research discussions and reflections in the general educational field with this research, as well as, to contribute significantly to the specific growth of musical education

A educação da mulher em Lima Barreto

Lima Barreto has built an educational conception of women in his fictional productions despite nuances inciting scholars to debate his writings and label him as misogynist and philogynist. Thus, the objective of this study is to comprehend, through signs present in his literary works, how women used to be educated in early twentieth century to accomplish the historical differences in gender relations. The main reason for this extract is the periodicity of his publications that started in 1900 by means of chronicles in newspapers and ended in 1922 after his death. For this, we identified codes and rules forged in the social processes to be assimilated by children through diverse institutions, aiming to incite the production of behaviors and social practices represented by the existence men and women in an ever changing society. Gender relations are analyzed within a society for their configuration concept by Nobert Elias (1970) as interdependence bonds among individuals. An investigative method proposed by Ginzburg (1989) was the most adequate to conduct the research on the work of Lima Barreto because it enables us to reconstruct the education concept for women. The dramas and novels analyzed point out the construction of categories such as women education, family, love and seduction revealing the engagement of Lima Barreto with the social problems of the period investigated. It was concluded that gender differentiation has come from family education which kept men and women in opposing sides giving them a marriage perspective that, after consummated, would bring frustration to women causing them to adopt confronting practices against domination strategies through celibacy or adultery. This research constitutes a reflection based on determined representations like justice, respect and duties that were the ideas defended by Lima Barreto in his writings, concerning both broader situations in social life and particular gender relations

Globos e mapas ao alcance das mãos : ensino de matemática numa perspectiva de alfabetização funcional na EJA

The following dissertation has as its main advantage the privilege of visualizing the literacy processes through the angle of the functional perspective, which does not see the literary process as a practice solely based on the decoding of alphabetical codes, and then allows for the opening of ample spaces for the allocation of mathematical skills in the realms of the functional literacy. The main object of this study was to investigate which are the contributions that a sequence of activities and of methodologies developed for the teaching of Geometry could provide for a part of the functional literacy process in mathematics of youngsters and adults of EJA, corresponding to the acquisition or to the improvement of skills related to the orientation capacity. The focus of the analyses consisted in the practice of these activities with the young and adult students of an EJA class belonging to a municipal public school of Natal/RN. The legacies of Paulo Freire about the redimensioning of the role of the teacher, of the students, of the knowledge and of their connections within the teaching-learning process, prevailed in the actions of the methodology implemented in the classroom and, especially, in the establishing of dialogic connections with the students, which directed all the observations and analyses regarding the collected information. The results indicated that the composition of articulations between the teaching of mathematics and the exploration of maps and the earth globe enabled the creation of multidisciplinary learning environments and situations, where we could observe, gradually, the development of procedures and attitudes indicating the evolution of space-visual type skills

A Internet como tecnointeração da aprendizagem: valorização da cultura e identidade juvenil

The present study investigates Internet as technological interaction in the school environment as a resource of the teaching-learning process. It aims to discuss the lack of synchronicity between proposals of educational access for Internet use and types of access and interaction applied by youngsters. For the development of this research, I resorted to a qualitative, descriptive and explanatory research focused on a group whose subjects are youngsters from eleven to fifteen years of age in a catholic school which belongs to a group of private teaching schools in Natal city, Rio Grande do Norte state. As methodological option it focus on a group and the observation of its participation, discourse analysis and ethnography, considering facts and data of the pedagogical practice concerning the focused theme, besides the attempt to know the youngsters everyday at school and the relationship between them and juvenile cultures. It recognizes the existence of two moments of the focused group: the first related to internet use like technological interaction; the second concerns to the way Internet is problematic as technological interaction in classroom learning. While contacting with youngsters, the study discusses the concepts of Media Environments, Culture, Identity, Network, Consumption and Citizenship. It recognizes that it is relevant for the school to consider Internet a pedagogical tool, directed not just at research, but mostly as learning environment and as learning construction in a collaborative way. It points out the need of approach between school and media environment, reevaluating the pedagogical practice, offering a new evaluation proposal (self-evaluation). It suggests a renewal in the teacher's pedagogical practice in the classroom and using Internet, valuing the connection between technological interaction and communication as motivation elements of student s learning construction and their effective participation in decisions involving citizenship. It gives priority to educational work directed at the establishment of dialogic relationship between codes, learning and contents, leading to the new findings domain in the media environment, enabling the development of abilities and performances directed at the recognition and consumption of information from a critical reading of the media

Em nome da república: escolas e tradições modernas

Our research aims to analyze some institutions of primary education in so-called First Republic in Natal/RN, when they were considered high standard institutions on training, dissemination and creation of national identity and republican traditions. Thus, we investigated to try to understand the creation of the new man and the invention of new traditions to confirm the status of republican modernity in two schools in Natal, the Colegio Americano, a private one, and a standard model of school, Augusto Severo, which is a public one. As a basis we have the history of institutions to analyze, paying close attention to consider the use of imitation in cultural patrimony as well as the use of strategies to distinguish. The concept of ownership follows, for present purposes, their focus of study on observation of diverse and contrasting use of these cultural objects, texts, readings and ideas from research institutions. For analysis of the link which occurs within the school environment, in every period of its history, we used the concept of school culture as a set of rules and practices which define knowledge to teach and conduct the introject. A culture that incorporates the school to keep a set with other religious cultures, political and popular of its time and space. In this sense, the educational institutions which we studied while showing what kind of in this work by preparing cultures, codes, different practices, and specific individuals they have, they were in important locations to provide modern cultural appropriation as a strategy for educational innovation and a factor of rationality and efficiency which could be observed and controlled, so gradually the modern school education was organized to produce its own society. As a challenge of affirmation and incorporating diverse social experiences to produce the modern, civilized man of the Republican time, the school, as part of the social life, which is singular in its practices, not only the set of reforms, decrees, laws and projects, but also as expressions of concept about life and society in terms of material, symbolic and cultural symbols in the social context in modernization. We focused on these two schools, because inside the wide cultural and material status of the city, they were the first republic schools which had the goal of having men and woman together culturally , with a view to adapting them to the modern movement to make them civilized / educated / rational . On this view, we would emphasize that this statement needs a reinvention as a new way through what is made at the schools which production of new spaces, practices, rites and what represents school, making and expressing a new identity, modern, different of the old symbols of the Empire. For this, nothing better than the organization of schooling, emphasizing on educating the individual and his/her responsibilities with the order and progress. We need to understand the past as a result of conflicts, including strengths and limitations within the historical and social context, and the invention of tradition as a process of formalization and ritualization of acts which want to perpetuate, as a reference to a group identity. These are practices and social educative representations which support the understanding of pedagogical and educational ideas at this historical moment, making a new way of being and doing in the Republican universe

O grupo escolar modelo augusto severo (1908-1928): vinte anos de formação de professores

Ce travail a pour objet d'étude le Groupe Scolaire Augusto Severo, situé à Natal, première institution du type dans l'État du Rio Grande do Norte. Il analyse la pratique pédagogique, le modèle d'éducation primaire et d'expérimentation des personnes en formation de l'École Normale de Natal, entre 1908 et l'année de 1928. Dans cette période, se sont produites des tentatives d'organisation scolaire par le biais de la Réforme de l‟Enseignement Primaire (1908) et de la Réforme de l‟Enseignement (1916). Nous nous sommes basés sur l'Histoire Culturelle définie à travers la conjonction de l'histoire des objets dans sa matérialité, des pratiques dans leurs différences et configurations, des dispositifs dans leurs variations. Nous avons utilisé les journaux A República et Diário do Natal, la revue Pedagogium, des Lois, des Décrets et Messages du Gouvernement, des Codes d'Enseignement et le Régime Interne des Groupes Scolaires, documents qui proviennent du fonds de l'Institut Historique et Géographique do Rio Grande do Norte (IHGRN) et des sources iconographiques, provenant de l'Institut du Patrimoine Historique et Artistique National (IPHAN/RN). Dans les Archives Publiques de l‟Etat (APE/RN) nous avons recherché les Livres d'Enregistrement des Groupes Scolaires et Écoles Isolées, Offices, Inscriptions, Rapports et Actes de réunions de la Direction Générale de l'Instruction Publique et Journal de Classe. Nous avons analysé l'action des professeurs dans cette institution primaire, ainsi que l'histoire des disciplines scolaires et des programmes d'enseignement, la problématique des contenus et méthodes. Nous avons observé que la méthode intuitive était la dynamique de la pratique pédagogique efficace et que les rites de récompense, les cérémonies civiques composaient l‟ensemble des idées modernisatrices de l‟époque

Trajetórias de estudantes da rede pública que ingressam, permanecem e obtém êxito numa universidade pública

L accès et la permanence des étudiants à l université sont très présents dans les débats actuels relatifs à l'enseignement supérieur. De nombreuses mesures sont prises dans les politiques d'accès dans le but de réduire les inégalités et d'encourager les étudiants ayant moins de chances d'entrer dans l'enseignement supérieur, comme les étudiants issus de l'enseignement public, qui ont encore un niveau inférieur à celui souhaité. Lorsque ces élèves réussissent à terminer leurs études secondaires, passer l'examen d'entrée et réussir leur entrée dans l'enseignement supérieur ils se considèrent comme « victorieux ». Cette étude (pour le Master de l UFRN), développée au sein du groupe de recherche de la formation et professionnalisation des enseignants (PPGed / UFRN), vise à étudier la trajectoire des élèves issus des écoles publiques qui accèdent à une université publique. Nous avons interviewé 12 étudiants, six de l'Université fédérale de Rio Grande do Norte (UFRN) et 6 de l'Université d'État de Bahia (UNEB) inscrits à différents cours du premier cycle (Licence). Nous cherchons savoir comment s est déroulé leurs parcours au sein de l'Université, notamment en ce qui concerne la préparation aux examens d'entrée à l université (Vestibular) , la motivation du choix de cours, la première année à l'université, les habitudes d'étude, la relation avec l'apprentissage et les perspectives quant à l'avenir des élèves interrogés. Nous nous sommes référés aux travaux menés par Zago (2006), Ramalho (2003), Charlot (1997), Galland et Gruel (2009), Coulon (2008), Tinto (1993), Doray et l'équipe canadienne du CIRST (2009). L'entrée à l'université comporte un triple processus, institutionnel (formelles et informelles), intellectuel (composantes cognitives et académiques) et social (vie sociale au sein de l'université). L'étudiant entre à l'université et y trouve une nouvelle culture, de nouvelles connaissances et devra apprendre à être universitaire. Apprendre à surmonter le moment de l étrangeté et bien passer par le processus de l'apprentissage des règles, des codes de son nouveau statut et s accommoder de sa position d étudiant à l'université, arrive enfin, le temps d'affiliation, c'est à dire, le moment de l'admission où l'étudiant se sent comme un «vétéran», et qu il peut dire que les dangers de l'abandon sont passés et qu il pourra continuer son parcours avec succès. Cette étude vise à apporter des connaissances nouvelles sur les étudiants issus des écoles publiques, comme contribution au domaine des politiques d'accès et de permanence à l université et de soutien pédagogique au sein de cette institution

Ensino do processo de enfermagem: significados percepções docentes na formação do enfermeiro

The implementation of the nursing process should be experienced by all nurses during their formative years. However, the lack of implementation of the nursing process for care planning during the educational process and the existing disorder in the formation process prompted the following research questions: What is the meaning of teaching the nursing process to the nursing professors? Do nursing professors use strategies and methods that promote critical thinking in their students? The objective of the study was to analyze the meaning that teaching of the nursing process has for the nursing faculty of the bachalaureate nursing course. Qualitative descriptive study conducted with a sample of 30 faculty members that taught nursing care courses in the nursing program of the Federal University of Rio Grande do Norte (UFRN) in Natal, RN. Two instruments were used, a questionaire and an interview guide. The questionnaire was designed to obtain sociodemographic, educational and work information, of faculty activities and of the teaching of nursing care. The guide was composed of five open questions regarding the understanding and perceptions of the nursing process, its utilization in teaching, and the nursing care teaching strategies. Interview data were submitted to content analysis techniques and interpreted according to the principles of Symbolic Interactionism. Six categories related to the analytical themes were identified: the nursing process as the guide for the care actions; clinical rationality; use of the care activities; teaching relevance; teaching barreirs; teaching strategies with focus on the abilities and competencies of the clinical rationale. Faculty perceptions regarding the teaching of the nursing process; nursing care approach in the nurses‟ formation. The study indicates that the participants understand the relevance of the nursing process a work instrument and that the use of this method during the nurses‟ formation enhances the abilities and competencies for critical thinking that is essencial for care. The strategies for teaching of abilities and competencies were identified, however the nursing faculty should use codes, direction and the influence so that the students can Interact and therefore stimulate the use of the nursing process

Aspectos linguístico-ergonômicos em rótulos: avaliação da linguagem verbo-visual de rótulos de embalagens para alimentos achocolatados

We have been living in a world of packed products. The package and the labels support the companies to communicate with the customers in addition to give protection, storage and convenience in proportion to the products that move in the price list. The labels mainly add up a value which helps the companies differ their products and increase the value of the brands among the final customers. However, the information given in the label are not clear sometimes. It displays a verbal-visual defective language resulted from a poor visibility, legibleness and comprehensibleness of the verbal and visual marks. The aim of this research is to verify, according to the costumers‟ view, the level of the clarity in the informative texts, harmony and ergonomic conformity of the package labels in the chocolate powder of the Claralate brand, considering the linguistic aspects presented on the labels. The criteria to evaluate the chocolate package selected were based on the linguistic field: the organization and the structure of the text derided from the classification of the textual genre; the clarity and the comprehension of the language utilized on those labels. From the ergonomic view, the informative and ergonomic conformity, based on the following requirements: legibility, symbols, characters, reading fields and intermission of the written lines. Therefore, the research done july 2007 and added july 2011 had a structured questionnaire in the interview put to the 118 customers of the chocolate package that go shopping in one of the two supermarkets in Floriano, Piauí São Jorge and/or Super Quaresma. The main results of the investigation show that the linguistic aspects in the informative texts of the labels provide the customers‟ expectancy partially, while the consideration of the informative ergonomic analyzed can contribute to the improvement of the information and consequent visual progress of those, on the labels of chocolate package investigated. As recommendation towards the maker of the product, the outcome of the research indicates: harmonize the proportion of the letters and numbers; enlarge the letters size; make the visual information more comprehensive determined by the reading field; put the expiry date in a better visual place

Estudo do efeito de dipolos em arranjos de antenas adaptativas de sistemas de comunicação DS-CDMA

This master dissertation introduces a study about some aspects that determine the aplication of adaptative arrays in DS-CDMA cellular systems. Some basics concepts and your evolution in the time about celular systems was detailed here, meanly the CDMA tecnique, specialy about spread-codes and funtionaly principies. Since this, the mobile radio enviroment, with your own caracteristcs, and the basics concepts about adaptive arrays, as powerfull spacial filter was aborded. Some adaptative algorithms was introduced too, these are integrants of the signals processing, and are answerable for weights update that influency directly in the radiation pattern of array. This study is based in a numerical analysis of adaptative array system behaviors related to the used antenna and array geometry types. All the simulations was done by Mathematica 4.0 software. The results for weights convergency, square mean error, gain, array pattern and supression capacity based the analisis made here, using RLS (supervisioned) and LSDRMTA (blind) algorithms

Algoritmo SOM com estrutura hierárquica e dinâmica aplicado a compressão de imagens

ln this work the implementation of the SOM (Self Organizing Maps) algorithm or Kohonen neural network is presented in the form of hierarchical structures, applied to the compression of images. The main objective of this approach is to develop an Hierarchical SOM algorithm with static structure and another one with dynamic structure to generate codebooks (books of codes) in the process of the image Vector Quantization (VQ), reducing the time of processing and obtaining a good rate of compression of images with a minimum degradation of the quality in relation to the original image. Both self-organizing neural networks developed here, were denominated HSOM, for static case, and DHSOM, for the dynamic case. ln the first form, the hierarchical structure is previously defined and in the later this structure grows in an automatic way in agreement with heuristic rules that explore the data of the training group without use of external parameters. For the network, the heuristic mIes determine the dynamics of growth, the pruning of ramifications criteria, the flexibility and the size of children maps. The LBO (Linde-Buzo-Oray) algorithm or K-means, one ofthe more used algorithms to develop codebook for Vector Quantization, was used together with the algorithm of Kohonen in its basic form, that is, not hierarchical, as a reference to compare the performance of the algorithms here proposed. A performance analysis between the two hierarchical structures is also accomplished in this work. The efficiency of the proposed processing is verified by the reduction in the complexity computational compared to the traditional algorithms, as well as, through the quantitative analysis of the images reconstructed in function of the parameters: (PSNR) peak signal-to-noise ratio and (MSE) medium squared error
