Κατασκευές συμπλήρωσης διατεταγμένων χώρωνΠαπαργύρη, Αθηνά 01 November 2010 (has links)
Στο κεφάλαιο 1 γίνεται μελέτη διατεταγμένων αλγεβρικών δομών. Δίνονται ορισμοί, αποδείξεις και στοιχειώδη αποτελέσματα, απαραίτητα σε όλη την πορεία της εργασίας. Ορίζουμε μερικώς διατεταγμένα σύνολα και μερική διάταξη σε αλγεβρικά συστήματα, βλέπουμε υπό ποίες προϋποθέσεις η μερική διάταξη επεκτείνεται σε ολική και άρα το σύνολο γίνεται ολικώς διατεταγμένο και στη συνέχεια τα διατεταγμένα σύνολα με μία εσωτερική πράξη ορίζουν μερικώς ή ολικώς διατεταγμένες ομάδες.
Στο κεφάλαιο 2 παρουσιάζουμε συμπληρώσεις διατεταγμένων συνόλων και συγκεκριμένα, τα συμπληρώματα Dedekind, Kurepa και Krasner καθώς και ορισμένες ιδιότητες αυτών. Ο Dedekind (1831-1916) όρισε τις τομές Dedekind με τη βοήθεια των οποίων επέκτεινε τη διάταξη των φυσικών στο σύνολο των πραγματικών και θεμελίωσε με αυτόν τον τρόπο το σύνολο αυτό ως ένα διατεταγμένο σώμα. Η κατασκευή της δομής των πραγματικών εφοδιασμένη με τις πράξεις της πρόσθεσης και του πολλαπλασιασμού και τη δίαταξη, καθώς και η κατασκευή της δομής του επιπέδου με τις ίδιες πραξεις και διάταξη κατά Dedekind παρουσιάζεται εκτενέστερα στο κεφάλαιο 3. Η γενίκευση της έννοιας του συμπληρώματος Kurepa και η εισαγωγή του συμπληρώματος Krasner, οφείλονται στον καθηγητή Λ. Ντόκα (1963).
Η μέθοδος του Dedekind της συμπλήρωσης με τομές δεν είναι η μόνη μέθοδος κατασκευής των πραγματικών αριθμών. Η μέθοδος του G. Cantor (1845-1918) της συμπλήρωσης με ακολουθίες, είναι η δεύτερη εξίσου σημαντική μέθοδος, την οποία θα παρουσιάσουμε στο κεφάλαιο 4.
Η μελέτη μας ολοκληρώνεται στο κεφάλαιο 5, όπου παρουσιάζεται ένα ενδιαφέρον αποτέλεσμα για τις μερικώς διατεταγμένες ομάδες και τις συνθήκες κάτω από τις οποίες αυτές επεκτείνονται σε ολικώς διατεταγμένες ομάδες, στηριζόμενοι στην εργασία “embedding groups into linear or lattice structures” των Κοντολάτου-Σταμπάκη (1987), όπου πραγματοποιούν επέκταση μίας μερικώς διατεταγμένης ομάδας, χρησιμοποιώντας τα αποτελέσματα του Fuchs για ύπαρξη επέκτασης ενός μερικώς διατεταγμένου συνόλου σε ολικώς διατεταγμένο. / In chapter 1 ordered algebraic structures are considered and we present certain definitions, proofs and elementary results which are necessary in the whole project. Partially ordered sets and partial order in algebraic systems is defined. Then we analyze under which conditions partial order can be extended to full order. This leads to fully ordered sets and those sets, along with an internal operation, define partially or fully ordered groups.
In chapter 2 we present specific ordered set complements and in particular those of Dedekind, Kurepa and Krasner and furthermore we mention some of their properties. Dedekind sections where introduced by Dedekind (1831-1916), who used them in order to extend the order of natural numbers to the set of real numbers, making this set an ordered field. The construction of the real numbers structure along with the internal operations of addition and multiplication and order and the construction of the plane structure with the same operations and order, using Dedekind theory, is analytically presented in chapter 3. Due to L. Docas (1963), Kurepa complement was generalized and Krasner complement was introduced.
Dedekind’s sections is not the only way to construct the set of real numbers. Another important method is that of G. Cantor (1845-1918), who used sequences for completion. We present this method in chapter 4.
Finally, in chapter 5, we consider a paper published by A. Kontolatou and J. Stabakis (1987) entitled “Embedding groups into linear or lattice structures”. Fuchs’s results on the extend existence of a partially ordered set to fully ordered set is used. Based on the Kontolatou-Stabakis paper, we present an interesting result for partially ordered groups and certain conditions of how to extend those groups to fully ordered ones.

O colunismo social de Ibrahim Sued : do capital simbólico à troca de favores /Saadi Tosi, Lamia Jorge January 2018 (has links)
Orientador: Laercio Fidelis Dias / Banca: José Petrúcio de Farias Júnior / Banca: Rogério Naques Faleiros / Banca: José Geraldo Alberto Bertoncini Poker / Banca: Rafael Salatini de Almeida / Resumo: O presente trabalho tem por objetivo compreender a trajetória profissional de Ibrahim Sued, descendente de imigrantes libaneses que se notabilizou por ter protagonizado a posição do mais emblemático colunista social, que foi reconhecido como inovador na maneira de fazer crônica social entre as décadas de 1940 a 1990. Sua trajetória profissional e pessoal foram marcadas por contradições e paradoxos que, entretanto, não o impediram de ascender socialmente e tornar-se um porta voz de personagens que transitavam pelo grand monde. Publicou ao longo desses anos diversos livros e mais de quinze mil colunas que atestam o fenômeno jornalístico. Não se limitou a assuntos amenos da vida em sociedade, de etiqueta e de moda transitando à conquista de furos de reportagens e informando sobre assuntos políticos, econômicos e de negócios. Os resultados almejados com essa pesquisa são relacionados à interpretação desse percurso não só no aspecto da crônica e do personagem em si, mas de como e por que o colunismo se tornou algo obrigatório nos jornais desde então. As hipóteses a partir das quais o presente trabalho se põe estão relacionadas: ao capital simbólico representado pelo campo da coluna social, ao papel desempenhado no relacionamento entre estabelecidos e outsiders, bem como de que maneira esses aspectos são reveladores da dinâmica social e das formas de reprodução de uma cultura social, a cultura social da troca de favores. / Abstract: This paper aims to understand the professional trajectory of Ibrahim Sued, a descendant of Lebanese immigrants who was notable for having played the position of the most emblematic social columnist (writer of Gossip Columns), who was recognized as an innovator in the way of social chronicling between the 1940s to 1990. His professional and personal trajectory were marked by contradictions and paradoxes that, however, did not prevent him from ascending socially and becoming a spokesperson for characters who traveled through the grand monde. He has published over the years several books and more than fifteen thousand columns that attest to the journalistic phenomenon. It was not limited to issues of life in society, etiquette and fashion, moving to the achievement of reporting holes and informing about political, economic and business issues. The results sought by this research are related to the interpretation of this course not only in the aspect of the chronicle and the character itself, but of how and why the columnism has become mandatory in the newspapers ever since. The hypotheses from which the present work is related are: the symbolic capital represented by the field of social column, the role played in the relationship between established and out-siders, as well as how these aspects are revealing of the social dynamics and forms of reproduction of a social culture, the social culture of the exchange of favors. / Resumen: El presente trabajo tiene por objetivo comprender la trayectoria profesional de Ibrahim Sued, descendiente de inmigrantes libaneses que se notó por haber protagonizado la posición del más emblemático columnista social, que fue reconocido como innovador en la manera de hacer crónica social entre las décadas de 1940 a 1990. Su trayectoria profesional y personal fueron marcadas por contradicciones y paradojas que, sin embargo, no le impidieron ascender socialmente y convertirse en un portavoz de personajes que transitaban por el grand monde. Publicó a lo largo de estos años diversos libros y más de quince mil columnas que atestiguan el fenómeno periodístico. No se limitó a asuntos amenos de la vida en sociedad, de etiqueta y de moda transitando a la conquista de agujeros de reportajes e informando sobre asuntos políticos, económicos y de negocios. Los resultados deseados con esta investigación se relacionan con la interpretación de este recorrido no sólo en el aspecto de la crónica y del personaje en sí, sino de cómo y por qué el columnismo se ha vuelto algo obligatorio en los periódicos desde entonces.

Previous issue date: 2011-02-03 / Este trabalho teve como objetivo verificar a exatidão e precisão das estimativas das variáveis diâmetro, altura e volume, considerando as estimativas dos parâmetros obtidos no ajuste do conjunto de dados pelo modelo original e pelas expressões de diâmetro e altura para diferentes modelos de afilamento e comprimento das seções. Para a realização do trabalho, foram cubados 70 fustes do híbrido Eucalyptus urophylla x Eucalyptus grandis em espaçamento de 3 x 2 m num talhão de 3,48 hectares com 8 anos de idade em seções de 0,5 m até atingir um diâmetro mínimo de 4 centímetros para o estudo das funções de afilamento. Para verificar a influência do comprimento das seções, todos os fustes foram medidos em dez comprimentos de seções diferentes correspondentes a 0,5 m, 1,0 m, 1,5 m, 2,0 m, 2,5 m, 3,0 m, 3,5 m, 4,0 m, 4,5 m e 5 m, começando da seção de 0,0 m até o diâmetro mínimo de 4 centímetros e separados em dois grupos, um considerando a influência da base e outro não. Os modelos utilizados na comparação das estimativas foram Baldwin, Demaerschalk, Kozak e Ormerod. No estudo da influência do comprimento das seções, utilizou-se o modelo de Demaerschalk nos diferentes comprimentos de seções analisadas. A precisão e acurácia das estimativas foram verificadas através da análise gráfica dos resíduos, do coeficiente de determinação ( ), do erro padrão da estimativa (Syx(%)), do viés (V), da média das diferenças (MD) e do desvio padrão das diferenças (DPD). Baseado nessas estatísticas foi feita uma classificação para determinar o modelo que propiciasse melhores estimativas das variáveis pelas diferentes formas de ajuste e comprimento das seções, estimando assim resultados mais exatos para as variáveis analisadas. As estimativas das variáveis diâmetro, altura e volume foram obtidas de maneira mais precisa para o modelo de Demaerschalk, considerando as estimativas dos parâmetros obtidos das expressões das variáveis diâmetro e altura em relação às estimativas baseadas nas estimativas dos parâmetros do modelo original. No estudo da influência do comprimento das seções, pode-se constatar que à medida em que se diminui o número de seções medidas no fuste, verifica-se a presença de tendência das estimativas das variáveis analisadas para os dois grupos. Comparando os resultados do grupo, com e sem influência da base, nota-se que as estimativas com influência são melhores, fato observado principalmente para a variável volume / This work had as objective to verify the accuracy and precision of estimates of diameter, height and volume variables, considering the estimates of the parameter obtained in the adjustment of data set by the original model and the expressions in diameter and height for different taper models and sections length. To conduct the study, 70 stems of Eucalyptus urophylla x Eucalyptus grandis hybrid were cubed in a spacing of 3 x 2 m, in a stand of 3,48 hectares with 8 years-old, in sections of 0,5 m until they reach a minimum diameter of 4 cm for the study of taper functions. To check the influence of the sections length, all stems were measured in ten different sections lengths corresponding to 0,5 m, 1,0 m, 1,5 m, 2,0 m, 2,5 m, 3,0 m, 3,5 m, 4,0 m, 4,5 m and 5 m, starting from the section of 0,0 m to a minimum diameter of 4 cm and separated into two groups, one considering the influence of the base and the other not. The models used in the comparison of the estimates are the ones proposed by Baldwin, Demaerschalk, Kozak and Ormerod. In the study of the sections length influence, it was used the model proposed by Demaerschalk in the different analyzed sections lengths. The precision and accuracy of the estimates were verified by graphic analysis of the waste, the determination coefficient ( ), estimated standard error (Syx(%)), bias (V), average of the differences (MD) and standard deviation of the differences (DPD). Based on these statistics, a classification was made to determine the model that would provide better variables estimates by different types of adjustment and sections length, estimating more accurate results for the analyzed variables. Diameter, height and volume variables estimates were obtained more accurately for the Demaerschalk model, considering the parameters estimates obtained from the expressions of the diameter and height variables in relation to estimates based on parameters estimates of the original model. In the study of the influence of the sections length, it can be seen that as the number of sections measures in the stem decreases, it becomes possible to verify the presence of tendency of the variables estimates for both groups. Comparing the results of the group, with and without influence of the basis, it is noted that the estimates with influence are better, which was observed mainly to the volume variable
