Sayat Nova and Armenian ashoogh musical tradition

Injejikian, Hasmig January 1990 (has links)
The main objective of this thesis is to show that the thirty melodies ascribed to the ashoogh Sayat Nova are melodically and rhythmically homogeneous, and that they bear similarity to both Armenian folk and sacred melodies. Since very little has been written on this topic in Occidental languages, it has been necessary to provide (1) a descriptive account of the ancient Armenian music; namely, vibassan, koosan, folk and sacred traditions; (2) a presentation of ashoogh poetic forms, rhyming schemes, and accentuation patterns, which are summarized for the first time in a chart with corresponding sources; (3) a chapter on Armenian tzayns as a background to the melodic analysis and codifications of Sayat Nova's melodies, which is contrary to the accepted practice of codifying these melodies with Greek modal names. / Professor Nigoghos Tahmizian's analysis of Sayat Nova melodies was used as a starting point. Furthermore, through analysis based primarily on available secondary sources, certain conclusions have been obtained: such as, the unity of rhythm/meter with language conventions, presence of specific melodic patterns, cadential endings, intervallic patterns and ranges in Sayat Nova melodies, as characterised by individual tzayn codifications. Further research is suggested to clarify codification of poetic forms, tzayn designations, and specifically, to solidify accentuation conventions of the Armenian language and of its dialects.

A Study of gas hydrates with ocean-bottom-seismometer data on the East Coast of Canada

Schlesinger, Angela 24 January 2013 (has links)
This dissertation presents a study on velocity modeling using ocean-bottom seismometer data (OBS) collected in 2004 and 2006 on the western Scotian slope. Gas hydrate and free gas concentrations and their distribution along the Scotian margin were derived based on the velocity results modeled with two different OBS data sets. A strong velocity increase (140-300 m/s) associated with gas hydrate was modeled for a depth of 220 m below seafloor (bsf). At the base of that high velocity zone (330 mbsf) the velocity decreases with 50-130 m/s. This depth is associated with the depth of the bottom-simulating reflector (BSR) observed in previous 2-D seismic reflection data. The gas hydrate concentrations (2-18 %) based on these velocities were calculated with an effective medium model. The velocity modeling shows that a sparser OBS spacing (~ 1 km) reveals more velocity uncertainties and smaller velocity contrasts than a denser (100 m) spaced OBS array. The results of the travel-time inverse modeling are applied in a waveform inverse modeling with OBS data in the second part of the thesis. The modeling tests were performed to obtain information on OBS instrument spacings necessary to detect low-concentration gas hydrate occurrences. The model runs show that an increase in instrument spacing leads to an increasing loss of model smoothness. However, large instrument spacings (>500 m) are beneficial for covering a wide target region with only using a few instruments, but decreasing the lateral resolution limits of the subsurface targets. In general half of the instrument spacing defines the lower boundary for the lateral width of the target structure. Waveform modeling with the 2006 OBS data has shown that low frequencies (<8 Hz) in the source spectrum are necessary to recover the background velocity of the model. The starting model derived from travel-time inversion of the 2006 data is not close enough to the true model. Thus the first-arrival waveforms do not match within half a cycle. Modeling with a starting frequency of 8 Hz and and applying data with a low signal-to-noise ratio (1.25) introduces artifacts into the final model result without updating the velocity. / Graduate

The Cape Breton fiddling narrative : innovation, preservation, dancing

Herdman, Jessica 11 1900 (has links)
With the fear of decline of the Cape Breton fiddling tradition after the airing of The Vanishing Cape Breton Fiddler by the CBC in 1971, both the Cape Breton community and ethnographers clamored to preserve and maintain the extant practices and discourse. While this allowed for performance contexts and practices to burgeon, it also solidified certain perspectives about the “diasporic preservation” and resultant “authenticity.” This work aims to trace the seeds and developments of the beliefs surrounding the Cape Breton fiddling tradition, from the idealizations of Enlightenment Scotland to the manipulation and commercialization of the folklore and Celticism of twentieth-century Nova Scotia. These contexts romanticized older practices as “authentic,” a construct that deeply impacted the narrative about the Cape Breton fiddling tradition. One of the most rooted and complex concepts in this narrative is that of “old style,” a term that came to represent the idealized performance practice in post-1971 Cape Breton fiddling. As models were sought for younger players to emulate, pre-1971 “master” fiddlers with innovative stylistic approaches began to be identified as “old style” players. The interstices of the tradition allowed more extreme stylistic experimentation to be accepted as “traditional,” while the symbiotic social practice of dancing necessitated relative conservatism. Analysis will show that “listening” tunes fell into the interstices of allowable innovation, while dance (particularly step-dance) tunes demanded certain “old style” techniques. A more holistic view of the complexities of the Cape Breton fiddling tradition follows from a perspective not only of the socio-musical elements that shaped the historical narrative, but also of the musical elements of this dance-oriented “old style.”

A Modular architecture for Cloud Federation

Panjwani, Rizwan 21 December 2015 (has links)
Cloud Computing is the next step in the evolution of the Internet. It provides seemingly unlimited computation and storage resources by abstracting the networking, hardware, and software components underneath. However, individual cloud service providers do not have unlimited resources to offer. Some of the tasks demand computational resources that these individual cloud service providers can not fulfill themselves. In such cases, it would be optimal for these providers to borrow resources from each other. The process where different cloud service providers pool their resources is called Cloud Federation. There are many aspects to Cloud Federation such as access control and interoperability. Access control ensures that only the permitted users can access these federated resources. Interoperability enables the end-user to have a seamless experience when accessing resources on federated clouds. In this thesis, we detail our project named GENI-SAVI Federation, in which we federated the GENI and SAVI cloud systems. We focus on the access control portion of the project while also discussing the interoperability aspect of it. / Graduate / 0984 / panjwani.riz@gmail.com

Poder e violência: Hannah Arendt e a Nova Esquerda

Magalhães, Simone Maria [UNESP] 12 September 2008 (has links) (PDF)
Made available in DSpace on 2014-06-11T19:23:37Z (GMT). No. of bitstreams: 0 Previous issue date: 2008-09-12Bitstream added on 2014-06-13T20:11:08Z : No. of bitstreams: 1 magalhaes_sm_me_mar.pdf: 602801 bytes, checksum: 83c83b4d66ce66ce7efd4fa80d2aa14b (MD5) / O presente trabalho tem por objetivo analisar a reflexão empreendida por Hannah Arendt (1906-1975) acerca dos fenômenos do poder e da violência, bem como sua crítica à Nova Esquerda , crítica essa que se apresenta de forma sistematizada em seu ensaio Sobre a violência, de 1969. A distinção entre poder e violência constitui-se, pois, em tema central do pensamento político da autora, que teve como motivação para sua reflexão a Rebelião Estudantil de 1968, a guerra do Vietnã e o papel da violência no âmbito da Nova Esquerda. Com efeito, o poder, para Arendt, é inerente a toda comunidade política e resulta da capacidade de agir conjuntamente. Por outro lado, a violência, que é instrumental, se funda na categoria meio-fim, e quando recobrada no âmbito do político é responsável por fazer desaparecer o poder. Portanto, poder e violência são assuntos opostos: quando um se afirma absoluto, o outro desaparece. Do contato com o pensamento de Arendt, percebemos que seu conceito de poder foi forjado tendo como referência a tradição da polis grega, a qual, no entendimento de Arendt, lança luzes sobre a derrocada dos valores da política moderna, bem como sobre a necessidade de resgatar a diferença entre as esferas pública e privada para fazer emergir o fenômeno originariamente político. Confrontando suas idéias com as de outros autores, consideramos que a análise de Arendt sobre o poder transcende completamente as relações conflituosas constitutivas da vida política e suas instituições tradicionais. Além disso, a rejeição da ação radical da Nova Esquerda, por esta autora, em grande medida parece engrossar o coro que recusa e rechaça a utopia, que significa, no contexto do “fim da ideologia”, a negação da perspectiva socialista em favor, mais uma vez, da “democracia” e do “pluralismo” norte-americanos. / The aim of this paper is to analyze the reflexion undertaken by Hannah Arendt (1906-1975) on the phenomena of power and violence as well as her critique of the New Left, which is presented systematically in her essay On Violence (1969). The distinction between power and violence thus comprises a central theme in her political thought, which has had as a motivation for her reflexion the Student Rebellion of 1968, the Vietnam war and the role of violence within the New Left. Indeed, the power, on Arendt's account, is inherent to every political community and it is a result of the ability to act jointly. Furthermore, the violence, that is instrumental, is based upon the means-end category and whenever stablished within the political sphere becomes responsible for causing the power to vanish. Therefore, power and violence are opposite subjects: as one becomes absolute, the other vanishes. By being in touch with Arendt's thinking we come to realize that her innovative concept of power has been forged having as reference the tradition of Greek polis, which, from Arendt's understanding, casts light on the defeat of the values of the modern Politics, as well as on the need of restoring the difference between public and private spheres to cause the originally political phenomenom to emerge. By putting her thoughts with those of other authors, we consider that Arednt's analysis of power goes completely beyond the conflicting constituents of political life and its traditional institutions. Moreover, the rejection of the extreme action of the New Left, by the author, largely seems to reinforce the chorus that refuses and rejects the utopia, which means, in the end of ideology context, the negation of the socialist perspective in behalf, once again, of the American democracy and pluralism.

A essa modalidade pode-se observar a construção subjetiva de mecanismos de respostas e de interpretação da realidade que resultam em atitudes e/ou numa ética comportamental capaz de traduzir os novos desafios que a realidade atual - denominada por alguns teóricos como sendo uma realidade pós-moderna - coloca para o indivíduo. Todavia, pode-se constatar que tais mecanismos de respostas, quando confrontados com o processo de alienação humana, tornam-se uma modalidade de resposta individual cujo potencial crítico fica ao nível superficial, reforçando um processo de privatização do indivíduo. / This dissertation had as the purpose of analyzing a modality peculiar comportamental, built during the last three decades of the century XX and that it can be apprehended through the movement New Era. For this modality it could be observed the subjective construction of mechanisms of answers and of interpretation of the reality that resulted in attitudes and or in an ethics comportamental capable to translate the new challenges that the current reality - denominated by some theoreticals as being a post-modern reality - it puts for the individual. Though, it can be verified that such mechanisms of answers, when confronted with the process of human alienation, they become a modality of individual answer which the critical potential is at the superficial level, reinforcing a process of the individualþs privatizations.

Dinâmica de crescimento de uma floresta ombrófila mista em Nova Prata, RS / Growth dynamics in a mixed araucaria forest in Nova Prata, Rio Grande do Sul, Brazil

Moscovich, Fabio Abel 04 April 2006 (has links)
The changes in the species composition, phytosociological structure and the growth dynamics (recruitment, mortality and dbh increment) have been studied in five permanent plots in a Mixed Araucaria Forest with different degrees of human intervention. The area located in Nova Prata county, Rio Grande do Sul, Brazil, has been measured during the 1995 2003 period, considering trees with diameter at breast height (dbh) over 30 cm. The floristic composition analysis shoes no significant changes during the studied period. Nevertheless, the trends to a lower number of strata indicate changes in the vertical structure, in the sense of a more stable one. The mortality rate has been higher than the recruitment rate and therefore, the dynamics cure not progressive but occurs in periods in which death is greater than inflows, creating gaps in the canopy than can allow the emergence of new individuals. The basal area annual increment can be estimated by an equation developed for the measured forest. Nevertheless, a specific equation had to be developed for Unit 5, that has showed a very different growth pattern, due to the consequences on it of a storm. The result of applying canonic correspondence analysis to the forest is the division in two phytosociological structures, according to the presence, or no, of Araucaria angustifolia. However, no significative changes in the internal phytosociological changes have been observed in these two structures. As observed before, mortality rates have been higher than recruitment rates, noting that this has been higher in the areas with out Araucaria, indicating a higher alteration in theses structures. The annual basal area increments can be estimated through regression equations developed for the two structures. The forest be managed according to the mosaic distribution pattern of the two structures (with and without Araucaria) observed. / As mudanças na composição florística, estrutura fitossociológica e os processos dinâmicos do crescimento: ingresso, mortalidade e incremento em área basal, foram estudados em cinco unidades de medição permanente de uma Floresta Ombrófila Mista com distintos graus de intervenção antrópica. A área, localizada no município de Nova Prata, RS, foi amostrada durante o período de 1995 a 2003, considerando os indivíduos arbóreos com circunferência à altura do peito maior ou igual a 30 cm. A análise de composição florística e estrutura fitossociológica mostram não haver mudanças significativas durante o período estudado. Foi observada uma mudança na composição vertical da floresta para estruturas com menor número de estratos significando uma maior estabilidade. As taxas de mortalidade foram superiores as taxas de ingresso, de modo que a dinâmica não se produz em forma gradativa mas sim por períodos onde a mortalidade é superior ao ingresso, gerando espaços no dossel, o que permite o surgimento de novos indivíduos. O incremento periódico anual em área basal pode ser estimado por uma equação própria desenvolvida para a floresta amostrada. Foi necessário desenvolver uma equação particular para a estimativa do incremento em área basal para a unidade amostral permanente Parcela 5 , pois esta mostrou um comportamento totalmente diferenciado do resto em conseqüência de um ciclone. A análise de correspondência canônica dividiu a floresta em duas estruturas diferenciadas pela presença dominante, ou não, de Araucaria angustifolia, fazendo necessário o trabalho em duas comunidades fitossociológicas. Analisando estas duas estruturas, também, não foram observadas mudanças significativas na estrutura fitossociológica no período estudado. As taxas de mortalidade também se apresentaram maiores que as de ingresso, registrando-se uma maior mortalidade na floresta sem presença dominante de araucária, o que indica uma maior alteração da estrutura. Os incrementos periódicos anuais em área basal podem ser estimados através de equações de regressão desenvolvidas para cada caso. Pelo observado é recomendável manejar a floresta fazendo uma divisão pelas diferença de vegetação em dois grupos com presença dominante de araucária e sem presença dominante desta espécie.

"Geração Núcleo-Elétrica: retrospectiva, situação atual e perspectivas futuras" / NUCLEAR ENERGY FOR ELECTRICITY GENERATION: HISTORICAL ANALYSIS, NOWADAYS SITUATION AND FUTURE

Sara Tania Mongelli 30 June 2006 (has links)
A primeira reação nuclear em cadeia autosustentada controlada foi obtida em 2 de dezembro de 1942. Daí em diante, o crescimento da energia nuclear, inicialmente estimulado por fins militares, foi rápido. Ás aplicações civis no setor da geração de eletricidade foram adquirindo, ao longo do tempo, um papel sempre mais importante nas matrizes energéticas de muitos paises. Em 1987, 418 reatores nucleares no mundo estavam produzindo eletricidade em escala comercial. Dois terços destes reatores eram localizados em 7 países: Estados Unidos, União Soviética, França, Reino Unido, Alemanha, Canadá e Japão. Nos anos 90, o setor nuclear experimentou um grande retardo, devido principalmente ao acidente de Chernobyl e a uma revisão otimista das perspectivas de esgotamento das reservas de petróleo e dos outros combustíveis fosseis. Em 2005 o número de reatores para geração de eletricidade em operação no mundo era de 441, não muito diferente do numero de reatores em operação em 1987. Neste panorama o primeiro objetivo deste trabalho é analisar o estado da arte da geração núcleo elétrica e do ciclo do combustível nos países acima mencionados, partindo de uma revisão histórica. O caso do Brasil é abordado também por ser o país onde este trabalho é desenvolvido. Uma vez concluído o quadro da geração núcleo elétrica a nível internacional, são analisadas as novas tecnologias no setor da geração núcleo elétrica e as tendências e as iniciativas para o futuro da utilização da energia nuclear. São também abordadas as principais questões que sempre acompanharam o debate sobre a energia nuclear: a segurança, o meio ambiente, a proliferação e o mais moderno conceito de desenvolvimento sustentável. É importante antecipar que o objetivo deste trabalho não é de julgar os acontecimentos e de influenciar a opinião do leitor a favor da energia nuclear, mas de selecionar materiais e dados para informar e assim fornecendo um texto que seja uma coleção de informações e sugestões de aprofundamentos e não uma fonte de polêmicas. / On December 2, 1942, man first initiated a self-sustaining nuclear chain reaction, and controlled it. Since then, nuclear energy development, firstly estimulated by military goals, was fast. But nuclear energy use for electricity production grew too, until becoming a very important energy source in the world energy mix. In 1987 there were in the world 418 nuclear reactors capable of producing commercially useful supplies of electricity. Over two thirds were in just seven countries: United States, Soviet Union, France, United Kingdom, Germany, Canada and Japan. In the 90s, nuclear energy development slowed down as a consequence of the Chernobyl accident and of the more optimistic evaluations of world oil resources. In 2005 the number of nuclear reactors commercially producing electricity amounted to 441, not much more than the 418 reactors operating in 1987. From this point of view, the primary scope of this work is to analyze the world pattern and the state of the art of nuclear power production focusing on the countries above mentioned. Brazil case is analyzed too, since this work has been developed there. Once this international outlook is concluded, the next step passes through the analyses of new technologies, tendencies and initiatives for the future development of nuclear energy. Since feelings run high in the debate about nuclear energy, some fundamental and fervent points are raised: security, environment, proliferation and sustainable development. Nevertheless, it is important to point out that effort has been made in this work not to take sides, but to be impartial in selecting materials and giving data. The scope is not to convert the reader to a pro-nuclear view but to inform and, in doing so, to provide a volume that is a textbook and not a piece of polemic.

A dinâmica dos espaços de cultura e lazer em Botafogo / The dynamic of the spaces of culture and leisure in Botafogo

Carlos Eduardo Braga de Mesquita 14 December 2010 (has links)
O processo de terciarização da economia, o qual se faz presente claramente desde os primórdios da cidade do Rio de Janeiro, promoveu profundas transformações na organização interna da cidade, o que implica em novos usos do espaço urbano e gera novos processos na cidade, sobretudo em nossa área de estudo, o bairro de Botafogo. O processo de globalização provoca mudanças significativas na economia mundial. A cidade, portanto se insere nos espaços de globalização e, assim, sofre mudanças que vão se refletir em sua estrutura urbana. Desta forma, o setor de serviços é dinamizado, reforçando, então, o processo de terciarização. Neste caso, se torna evidente a relação entre urbanização as atividades terciárias. Percebe-se, assim, o surgimento de um novo modelo de urbanização, atrelado à presença destas atividades terciárias, as quais serão de suma importância para a constituição de novas centralidades no espaço interno da cidade, como é o caso de Botafogo. Neste contexto, os espaços de cultura e lazer têm fundamental importância, visto que atraem fluxos de consumidores, os quais se aproveitam da infraestrutura proporcionada pelo Estado, sobretudo de transportes, através do metrô e das inúmeras linhas de ônibus que servem o bairro. Os espaços de cultura e lazer possuem uma grande importância no contexto de renovação de Botafogo, uma vez que o bairro apresenta uma grande concentração de equipamentos desta natureza, os quais contribuem para uma maior circulação de pessoas em seu espaço interno. Observam-se duas áreas de concentração destes espaços em Botafogo, as quais se localizam nas extremidades e adjacências do principal eixo viário do bairro, onde podemos encontrar também onde se concentram serviços especializados. Então, podemos dizer que, na esfera do consumo, estes espaços de cultura e lazer surgem como resultado de ações públicas e privadas. Os espaços de cultura e lazer promovem uma nova dinâmica a Botafogo e gera impactos na economia urbana do Rio de Janeiro. São responsáveis pelo surgimento de uma nova centralidade no âmbito da cidade e contribuem, portanto, para o processo de reestruturação urbana da cidade do Rio de Janeiro / The process of outsourcing of the economy, which clearly is present since the beginnings of the city of Rio de Janeiro, fostered profound changes in the internal organization of the city, which involves new uses of urban space and creates new processes in the city, especially in our study area, the neighborhood of Botafogo. The globalization process caused significant changes in the global economy. The city therefore fall within the spaces of globalization and thus undergoes changes that will be reflected in its urban structure. Thus, the service sector is driven by strengthening, then the process of outsourcing. In this case, it becomes apparent the relationship between urbanization tertiary activities. It is understood, therefore, the emergence of a new model of urbanization, coupled with the presence of these tertiary activities, which will be of paramount importance for the establishment of new centers in the inner space of the city, as is the case with Botafogo. In this context, the spaces of culture and leisure are of fundamental importance, since they attract flows of consumers who take advantage of the infrastructure provided by the State, especially in transport, through the subway and numerous bus lines that serve the neighborhood. The spaces for culture and leisure have a great importance in the renewal of Botafogo, once the district has a large concentration of such equipment, which contribute to an increased movement of people in your inner space. Shows two areas of concentration of these spaces in Botafogo, which are located at the ends and adjacent to the main road axis of the neighborhood, where we also find a large concentration of specialized services. So we can say that the sphere of consumption, these spaces of culture and leisure arise as a result of public and private actions. Spaces for culture and leisure promote a new dynamic to Botafogo and generate impacts in the urban economy of Rio de Janeiro. Are responsible for the emergence of a new center within the city and thus contribute to the restructuring of the town of Rio de Janeiro.

Nova Alta Paulista, 1930-2006 : entre memórias e sonhos. Do desenvolvimento contido ao projeto político de desenvolvimento regional /

Gil, Izabel Castanha. January 2007 (has links)
Orientador: Bernardo Mançano Fernandes / Banca: Eliseu Savério Sposito / Banca: Everaldo Santos Melazzo / Banca: Elpídio Serra / Banca: Rubens Galdino da Silva / Abstract: Development, despite the completion the term incites, occurs unequally in the midst of different areas and regions. According to the monopolistic logic that bases the social and economical process, society understakes the environment wich we are daily exposed to Nova Alta Paulista, located in the farwest of the state of São Paulo, was developed in the mid of the twentieth century, together with the urban industrialization on course in the metropolitan area in state control. External factors, such as the international conjuncture, besides the governmentþs move inspired by the national development trend, combined with internal factors, such as certain characteristics of the environment, local policies, and the predominance of a resistant conception to the consolidation of regional debates, contributed to a minor socioeconomical situation in the context of the state. Current affairs are leading us to important changes on environmental and territorial organization under the tendency to renewable sources of energy. Such fact demands reflection and study on its impact over development in the region. In this study, the objectives were to analyse how the socioeconomical development of Nova Alta Paulista took place to understand its current face; to examine the adjustment to the idea of a suppressed region to designate its socioeconomical and political cultural characteristics; to make use of a new approach that suprpasses the conception of territory, conceiving it as a social development which results from the conception of region to a territorial notion; to verify If the idea of regional development, named endogeneous development, will be able to territorialize, beginning with the socioeconomical actions under taken by local parties and segments in conflict with current hegemonical powers...
