CALDERON, IPINZA MARCELO. "An Analytic Method for S-Expansion involving Resonance and Reduction." Doctoral thesis, Politecnico di Torino, 2017. http://hdl.handle.net/11583/2679235.
Full textAbstract:
In this work we describe an analytic method able to give the multiplication table(s) of the set(s) involved in an S-expansion process (with either resonance or 0-resonant-reduction) for reaching a target Lie (super)algebra from a starting one,after having properly chosen the partitions over subspaces of the considered (super)algebras. This analytic method gives us a simple set of expressions to find the subset decomposition of the set(s) involved in the process. Then, we use the information coming from both the initial (super)algebra and the target one for reaching the multiplication table(s) of the mentioned set(s). We also give some interesting examples of application which check and corroborate our analytic procedure andgeneralize some result already presented in the literature

Full textAbstract:
This thesis is about a new methd to perform the S-expansion procedure and studies in extended supergravites. In the present work, the concept of zero-reduction has been extended reproducing a generalized Inönü-Wigner contraction. This involves an innite abelian semigroup and the removal of an ideal subalgebra. We refer about the use of theorem VII.2 of the reference [20] which serves to construct the topological invariant of a respective S-expanded algebra from another of which the bilinear form is known, therefore is an extension and generalization of the mentioned theorem. This procedure allows to develop the dynamics and construct the Lagrangians of several theories. This work reproduces the results already presented in the literature, concerning the generalized Inönü-Wigner contraction, and also gives some new features. Moreover, it gives a connection between the contraction processes and the expansion methods introduced in [17], which was an open question already mentioned in [12]. Also is shows one of the interesting applications, which is to obtain a particular hidden Maxwell superalgebra underlying supergravity in four dimensions. Thus we have written the hidden Maxwell superalgebra in the Maurer-Cartan formalism, and then, we have considered the parametrization of the 3-form A(3) in terms of 1-forms, in order to show the way in which the trivial boundary contribution in four dimensions, dA(3), can be naturally extended by considering particular contributions to the structure of the extra fermionic generator, appearing in the hidden Maxwell superalgebra. These extensions contain terms which involve the cosmological constant. Interestingly, the presence of these
terms depends strictly on the form of the extra fermionic generators appearing in this hidden extension of D = 4 supergravity. Besides, we have reviewed some concepts of the S-expansion. We show especially, how S-expansion procedure aects the geometry of a Lie group: was
found how the magnitude of a vector change and the angle between two vectors. About the kind of algebra, after apply an S-expansion, it is a non-simple Lie algebra. Then, considering resonance and reduction, we built an analytic method able to give us the multiplication table(s) of the set(s) involved in an Sexpansion process for reaching a target Lie (super)algebra from a starting one, after having chosen properly the partitions over subspaces of the considered (super)algebras. Furthermore, we study in the context of ungauged supergravities, the symmetry under the kinetic part in the action and the realization to a global symmetry group G. Moreover, we show the use of the solution generating technique. As
a rst step in the unnished research we work with the AdS metric with the global group G2(2),which it is the global symmetry group of the 3D description of N = 2 supergravity coupled to a vector multiplet [13], where we found the charges. Considering that a solution with cosmological constant is always gauged in extended supergravities [36], it is planned to investigate the applicability of the solution generating technique on gauged theories asymptotically at, i.e AdS metric.

Full textAbstract:
This thesis explores the expansion of British television in the 1950s and 1960s and its relationship to social and cultural change. During this period, television developed into an industry and mass medium and this coincided with a cultural shift from a seemingly consensual society of post-war austerity to a society characterised by fragmentation, individualism and consumerism. By combining a re-examination of existing histories of British television with a discussion of television programmes and sociological theory, this thesis explores the complex relationship between the expansion of television and that social and cultural change. The thesis shows how television represented these changes, and how it presented competing discourses about consumer culture in a range of programmes including action adventure series, pop music and women's programmes. It also demonstrates how television promoted class and cultural conflict in its individual programmes such as situation comedies and dramas, and through juxtaposition of high and low cultural vales, themes and forms in its mixed programme schedule. By looking at issues such as intimacy, performance, authenticity and sociability, the thesis argues that television promoted its own status as an increasingly centralised cultural form. It proposes that television established social categories which became embedded and naturalised over time, and this created the potential to define social experience. The thesis therefore concludes that the examination of the expansion of television in the 1950s and 1960s is of importance for understanding the operation of media power today.

As globalization increases integration, a new playing field is emerging which is driving the need for operational efficiencies and alignment of complementary capabilities among countries to build sustainable models and integrated offerings. As demands increase, companies are turning to effective project management as means to control operations and countries are increasing the amount of mega projects to boost their competitiveness and global footprint. Given the scale, complexity, political nature, multicultural makeup, and high level of visibility; mega projects rely on successful stakeholder management to effectively manage its operational, tactical, and strategic levels to execute their mission. This paper examines the success drivers of mega projects and presents an in depth stakeholder assessment of the Panama Canal Expansion mega project to identify the perceived value to its stakeholder community. The stakeholder categories include: the Panama Canal Authority, subcontractors executing the expansion project, customers of the canal in Panama and U.S., as well as the communities surrounding the Panama Canal and ports in the U.S. East Coast. The conclusion of this paper captures the relationship between the effective stakeholder engagement from the Panama Canal Authority, the perceived value of the Panamanian stakeholders, and compares it to U.S. based mega projects being executed simultaneously to allow the U.S. East Coast ports to accommodate increased cargo volumes.

Esta dissertação discute o hibridismo presente nos livros-objeto infantis contemporâneos, na tentativa de evidenciar como os fundamentos da natureza híbrida da linguagem do Design e a experiência intersemiótica revelam-se como interações presentes em enredos multissensoriais, expandindo as narrativas encontradas no livro-objeto infantil. O olhar sobre o ato de ler não se restringe à decifração de letras grafadas em qualquer que seja o suporte, mas se expande para a absorção das representatividades estabelecidas. O design de livros influencia a leitura não apenas em aspectos funcionais, mas também simbólicos e, por isso, pode ser considerado um mediador de leitura, que conduz o leitor em sua jornada. A dissertação apresenta a leitura de dois livros-objeto infantis selecionados nas obras de Kveta Pacovská e Roger Mello, designers/ilustradores/ artistas plásticos reconhecidos internacionalmente com o prêmio Hans Christian Andersen. Buscou-se verificar os processos com os quais são ativadas e ampliadas as suas histórias no hibridismo dos processos narrativos. Para isso, a dissertação se apoiou na concepção do híbrido como categoria analítica proposta por Braida (2012).
This thesis discusses the hybridism in the contemporary children s Object Books, in an attempt to elucidate how the hybrid nature of the design language and of the intersemiotic experience, reveal the interactions in the multisensory stories, expanding the narratives found in children s Object Books. A look at the act of reading is not restricted to the deciphering of written letters – in whatever sort of support, but in the absorption of established representativeness. Book design influences that reading, not only in functional aspects, but also in symbolic ones, and that is why it can be considered as a reading-mediator, driving the reader through his journey. The thesis presents the reading of two children s object-books chosen from the works from Kveta Pacovská and Roger Mello, both internationally recognized designers/illustrators and plastic artists awarded with the Hans Christian Andersen prize. In these books, the progress from which the histories were activated and amplified in the hybridism of the narrative process was accounted. The theses is based on the notion of hybrid as an analytical category as proposed by Braida (2012).

Full textAbstract:
Sweden is a country with close to zero fossil-fuel dependency in their electricity generation. The Swedish government has established specific goals that the Swedish electricity system should consist solely of renewable energy, as well as achieve zero net emissions in electricity generation within 25 years. To reach these goals, Sweden have been investing avidly in wind power over the last 15 years, making them one of Europe’s leading investors in the technology. However, this has started public debate on the topic as humans-, as well as flora and fauna, are affected negatively by the turbines. This paper investigates public benefits and costs of further onshore wind power expansion in Sweden. The focus is to analyse if an increased onshore wind power expansion can cease imports of fossil-fuelled electricity, Sweden’s main source of fossil-fuel dependent electricity. Furthermore, the aim is to determine if a wind power expansion of magnitude to eliminate these imports of fossil-fuelled electricity is of public benefit or not. A regression model gives support for the conclusion that an increased wind power production diminishes imports of fossil-fuelled electricity. Moreover, the magnitude of wind power production necessary to completely eliminate these imports are combined with public benefits and costs for onshore wind power to evaluate the socioeconomic value of the expansion. This is evaluated using the present-value method and included in a cost-benefit analysis. The results suggest that an increased onshore wind power expansion is of public benefit if most added electricity from the expansion can replace electricity generated from greenhouse gas-intense facilities abroad, and thus mitigate greenhouse gas emissions. On the other hand, if less added electricity from the wind power expansion is used to replace production from greenhouse gas-intense facilities, public benefits decrease whilst subject to the same costs. Moreover, if production from the onshore wind power expansion solely mitigates the greenhouse gases from Sweden’s imports of fossil-fuelled electricity, public costs exceed the public benefits, and the total socioeconomic value of the investment is negative. The conclusion of this paper suggests that a further onshore wind power expansion is of public benefit if its production is guaranteed to mitigate substantial amounts of greenhouse gases through exported electricity.

Full textAbstract:
Este trabalho consiste em um estudo das mudanças sociais nas práticas educativas
da comunidade de Nova Vida, formada por famílias de pequenos agricultores e
pescadores e localizada no município de Barcarena, Amazônia Oriental (PA). O
trabalho articula os conceitos de cultura e processo educativo para desenvolver uma
análise das relações sócio-espaciais desta comunidade, conformadas tanto pelo contexto
ambiental da floresta amazônica quanto pelas transformações determinadas pelos
deslocamentos compulsórios sofridos por suas famílias e promovidos por
empreendimentos transnacionais ligados à produção de caulim. Isso implica apreender
as antigas e as novas práticas educativas da comunidade, promovidas tanto pelas
mudanças de contexto ambiental que lhe são impostas, quanto por sua inserção em um
campo mais amplo de mobilização e organização sócio-política críticas aos
empreendimentos transnacionais na região. Para realizar esta análise, assumimos como
fio condutor do estudo dos dois processos de deslocamento compulsório vividos pela
comunidade, impostos pela empresa de capital transnacional Pará Pigmentos S/A, com a
anuência do estado do Pará e de órgãos do Governo Federal. Assim, a questão central
deste trabalho pode ser traduzida na seguinte questão: Como as dinâmicas territoriais
resultantes da presença da empresa mineradora e dos deslocamentos da comunidade
instituiram novos saberes e fazeres, novos agentes, processos de ensino e
aprendizagem, conteúdos e objetivos pedagógicos para a citada comunidade? Para
responder a esta questão, adotamos o método etnográfico, a pesquisa documental, as
entrevistas abertas e as histórias de vida, dando ênfase à identificação dos atores sociais,
dos diferentes saberes que vão se impondo por meio das mudanças sociais provocadas
pelos deslocamentos e dos modelos de ensino-aprendizagem que vão sendo impostos,
propostos e inventados. O trabalho inicia com a contextualização da comunidade na
dinâmica de reestruturação capitalista em curso no município de Barcarena,
posteriormente apresenta-se a organização social e cultura da comunidade, seguida da
descrição dos dois processo de deslocamento sofridos pela comunidade e seus impactos
no saberes e fazeres, culminando com uma análise da situação atual da comunidade e
seus aprendizados como sujeito político.This paper work is a study of social changes in educational practices of the community of Nova Vida, made up of small family farmers and fishermen, located in Barcarena, Eastern Amazonia (PA). The work articulates the concepts of culture and educational process to develop an analysis of socio-spatial relations of this community, shaped by both the environmental context of the Amazon forest as the determined by changes in the compulsory relocation suffered by their families and promoted by transnational ventures linked to production of kaolin. This means seizing the old and new educational practices of the community, promoted both by changes in environmental context that are imposed, and for its insertion in a broader field of mobilization and organization socio-political critiques of transnational ventures in the region. In this analysis, we assumed as a conducting wire a study of two cases of compulsory displacement experienced by the community, imposed by the company of transnational capital Pigments Para S/A, with the concurrence of the state of Para and Federal Government agencies. Thus, the crux of this work can be translated into the following question: How territorial dynamics resulting from the presence of the mining company and the displacements of the community instituted new knowledge and procedures, new agents, processes of teaching and learning, pedagogical content and objectives to the cited community? To answer this question, we adopted the ethnographic method, documentary research, open interviews and the life history, emphasizing the identification of social actors, the different knowledge that will be imposing through by social changes caused by displacement and models teaching and learning that are being taxes, proposed and invented. The work begins with the context of the community in the dynamics of capitalist restructuring in Barcarena then presents the social organization and cultural of the community, followed by the description of both the process of displacement suffered by the community and its impact on knowledge and practices culminating with an analysis of the current situation of the community and their learning as a political subject.

Full textAbstract:
This research has developed several models and methodologies with the aim of improving the accuracy and applicability of reliability predictions for complex repairable systems. A repairable system is usually defined as one that will be repaired to recover its functions after each failure. Physical assets such as machines, buildings, vehicles are often repairable. Optimal maintenance strategies require the prediction of the reliability of complex repairable systems accurately. Numerous models and methods have been developed for predicting system reliability. After an extensive literature review, several limitations in the existing research and needs for future research have been identified. These include the follows: the need for an effective method to predict the reliability of an asset with multiple preventive maintenance intervals during its entire life span; the need for considering interactions among failures of components in a system; and the need for an effective method for predicting reliability with sparse or zero failure data. In this research, the Split System Approach (SSA), an Analytical Model for Interactive Failures (AMIF), the Extended SSA (ESSA) and the Proportional Covariate Model (PCM), were developed by the candidate to meet the needs identified previously, in an effective manner. These new methodologies/models are expected to rectify the identified limitations of current models and significantly improve the accuracy of the reliability prediction of existing models for repairable systems. The characteristics of the reliability of a system will alter after regular preventive maintenance. This alternation makes prediction of the reliability of complex repairable systems difficult, especially when the prediction covers a number of imperfect preventive maintenance actions over multiple intervals during the asset's lifetime. The SSA uses a new concept to address this issue effectively and splits a system into repaired and unrepaired parts virtually. SSA has been used to analyse system reliability at the component level and to address different states of a repairable system after single or multiple preventive maintenance activities over multiple intervals. The results obtained from this investigation demonstrate that SSA has an excellent ability to support the making of optimal asset preventive maintenance decisions over its whole life. It is noted that SSA, like most existing models, is based on the assumption that failures are independent of each other. This assumption is often unrealistic in industrial circumstances and may lead to unacceptable prediction errors. To ensure the accuracy of reliability prediction, interactive failures were considered. The concept of interactive failure presented in this thesis is a new variant of the definition of failure. The candidate has made several original contributions such as introducing and defining related concepts and terminologies, developing a model to analyse interactive failures quantitatively and revealing that interactive failure can be either stable or unstable. The research results effectively assist in avoiding unstable interactive relationship in machinery during its design phase. This research on interactive failures pioneers a new area of reliability prediction and enables the estimation of failure probabilities more precisely. ESSA was developed through an integration of SSA and AMIF. ESSA is the first effective method to address the reliability prediction of systems with interactive failures and with multiple preventive maintenance actions over multiple intervals. It enhances the capability of SSA and AMIF. PCM was developed to further enhance the capability of the above methodologies/models. It addresses the issue of reliability prediction using both failure data and condition data. The philosophy and procedure of PCM are different from existing models such as the Proportional Hazard Model (PHM). PCM has been used successfully to investigate the hazard of gearboxes and truck engines. The candidate demonstrated that PCM had several unique features: 1) it automatically tracks the changing characteristics of the hazard of a system using symptom indicators; 2) it estimates the hazard of a system using symptom indicators without historical failure data; 3) it reduces the influence of fluctuations in condition monitoring data on hazard estimation. These newly developed methodologies/models have been verified using simulations, industrial case studies and laboratory experiments. The research outcomes of this research are expected to enrich the body of knowledge in reliability prediction through effectively addressing some limitations of existing models and exploring the area of interactive failures.

O significativo investimento em desenvolvimento tecnológico associado aos fatores ambientais, como disponibilidade de recursos naturais, clima e solo elevaram o Brasil ao patamar de maior produtor mundial de cana-de-açúcar, matéria-prima do açúcar e do etanol. Atualmente, o país exporta açúcar para mais de 100 países. Em relação ao etanol, esse vem se destacando no cenário mundial devido à viabilidade econômica e à necessidade de se utilizar energia renovável, em substituição aos combustíveis fósseis, com o intuito de mitigar o efeito estufa. Sendo assim, as perspectivas mundiais para a produção e, principalmente, consumo do etanol são favoráveis. Para o Brasil, devido à alta demanda mundial por açúcar e biocombustíveis, o zoneamento agroecológico da cana-de-açúcar, que apresenta uma seleção de terras potenciais para a expansão do seu cultivo visando uma produção sustentável, é uma necessidade imperiosa. Entretanto, os processos de mudança de uso e cobertura do solo são complexos e podem causar impactos, tais como: desertificação, perda da biodiversidade, poluição de ar, degradação dos componentes ambientais água e solo. Esse trabalho acadêmico visou estimar o escorrimento superficial e a produção de sedimentos em área consolidada e em área que encontra-se em expansão do cultivo da cana-de-açúcar para a produção de açúcar e etanol. Para isso, com base no Zoneamento Agroecológico da Cana-de-açúcar (ZAE Cana) que indica as áreas aptas ao cultivo da cana-de-açúcar, foram selecionadas duas áreas de estudo que possuem alta aptidão para a expansão da cana-de-açúcar. São elas: a Microbacia hidrográfica do ribeirão das Guabirobas (MBH-G) localizada no município de São Carlos - SP, região onde a cultura da cana-de-açúcar é consolidada e; a Microbacia hidrográfica córrego da Onça (MBH-O), localizada na região oeste do Estado de São Paulo, nos municípios de Ilha Solteira e Itapura, região onde a cultura da cana-de-açúcar encontra-se em expansão. O modelo de simulação espacial usado no trabalho é o Conversion of Land Use and its Effects at small region extent (CLUE-S), desenvolvido pela Universidade de Wageningen (Holanda). A aplicação satisfatória do CLUE-S permitiu o desenvolvimento de cenários futuros de uso e cobertura do solo com o intuito de simular a expansão da cultura da cana-de-açúcar em paisagens com diferentes características. A posteriori, foi estimada o escorrimento superficial e a produção de sedimentos desses cenários com o auxílio do modelo Soil and Water Assessment Tool (SWAT). O SWAT foi sensível aos cenários, possibilitando a geração de resultados consistentes, qualitativa e quantitativamente para cada um deles, o que permitiu verificar as suas particularidades. Vale ressaltar que a avaliação ex-ante dos impactos ambientais na área de expansão da cultura da cana-de-açúcar em diferentes cenários pode direcionar ações de políticas públicas e de planejamento sócio-econômico-ambiental, dentre outros.The significant investments in technological development associated to environmental factors, such as the availability of natural resources, for instance, climate and soil, have led Brazil to become the world\'s largest producer of sugarcane, the raw material used in the manufacture of ethanol and sugar. Currently, the country exports sugar to more than 100 countries. Ethanol has become globally eminent due to its economic feasibility and the need of clean and renewable energy rather than of fossil fuels in order to mitigate the greenhouse effect. Therefore, the global perspectives on the production and especially the consumption of ethanol are favorable. Due to the high global demand for sugar and biofuels, the agro-ecological zoning of sugarcane, which features a selection of potential areas for cultivation expansion aiming at sustainable production, is a fundamental necessity for Brazil. However, the changes inland use and land cover are complex processes and can cause impacts such as desertification, biodiversity loss, air pollution, and degradation of environmental components such as water and soil. This research aims to estimate the sediment yield and runoff in areas where the culture of sugarcane is consolidated and in areas of sugarcane expansion for the production of sugar and ethanol. Accordingly, based on the Agro-Ecological Zoning for Sugarcane (ZAE Cana), which indicates suitable areas for sugarcane cultivation, two study areas that have high potential for the expansion of sugarcane were selected, namely the microbacia hidrográfica do ribeirão das Guabirobas/MBH-G (Ribeirão das Guabirobas micro-drainage basin), located in the city of São Carlos - SP, a region where the culture of sugarcane is consolidated, and the microbacia hidrográfica córrego da Onça/MBH-O (córrego da Onça micro-drainage basin), located in the western region of the state of São Paulo, in the cities of Ilha Solteira and Itapura, an area of sugarcane expansion, i.e. a sugarcane expansion region. The spatial simulation model used in this research is the Conversion of Land Use and its Effects at small region extent (CLUE-S), developed by the University of Wageningen, Netherlands. Making use of this methodology, future land use and land cover scenarios were created in order to simulate the expansion of sugarcane cultivation in areas with different characteristics. Subsequently, the sediment yield and superficial runoff in these scenarios were estimated with the help of the SWAT model (Soil and Water Assessment Tool).This model was sensitive to both scenarios allowing the generation of consistent qualitative and quantitative results for each scenario enabling the identification of their particularities. It is noteworthy that the ex-ante evaluation of environmental impacts on areas of sugarcane expansion in different scenarios can guide public policy actions and socio-economic and environmental planning among others.

These new methodologies/models are expected to rectify the identified limitations of current models and significantly improve the accuracy of the reliability prediction of existing models for repairable systems. The characteristics of the reliability of a system will alter after regular preventive maintenance. This alternation makes prediction of the reliability of complex repairable systems difficult, especially when the prediction covers a number of imperfect preventive maintenance actions over multiple intervals during the asset's lifetime. The SSA uses a new concept to address this issue effectively and splits a system into repaired and unrepaired parts virtually. SSA has been used to analyse system reliability at the component level and to address different states of a repairable system after single or multiple preventive maintenance activities over multiple intervals. The results obtained from this investigation demonstrate that SSA has an excellent ability to support the making of optimal asset preventive maintenance decisions over its whole life. It is noted that SSA, like most existing models, is based on the assumption that failures are independent of each other. This assumption is often unrealistic in industrial circumstances and may lead to unacceptable prediction errors. To ensure the accuracy of reliability prediction, interactive failures were considered. The concept of interactive failure presented in this thesis is a new variant of the definition of failure. The candidate has made several original contributions such as introducing and defining related concepts and terminologies, developing a model to analyse interactive failures quantitatively and revealing that interactive failure can be either stable or unstable. The research results effectively assist in avoiding unstable interactive relationship in machinery during its design phase. This research on interactive failures pioneers a new area of reliability prediction and enables the estimation of failure probabilities more precisely. ESSA was developed through an integration of SSA and AMIF. ESSA is the first effective method to address the reliability prediction of systems with interactive failures and with multiple preventive maintenance actions over multiple intervals. It enhances the capability of SSA and AMIF. PCM was developed to further enhance the capability of the above methodologies/models. It addresses the issue of reliability prediction using both failure data and condition data. The philosophy and procedure of PCM are different from existing models such as the Proportional Hazard Model (PHM). PCM has been used successfully to investigate the hazard of gearboxes and truck engines. The candidate demonstrated that PCM had several unique features: 1) it automatically tracks the changing characteristics of the hazard of a system using symptom indicators; 2) it estimates the hazard of a system using symptom indicators without historical failure data; 3) it reduces the influence of fluctuations in condition monitoring data on hazard estimation. These newly developed methodologies/models have been verified using simulations, industrial case studies and laboratory experiments. The research outcomes of this research are expected to enrich the body of knowledge in reliability prediction through effectively addressing some limitations of existing models and exploring the area of interactive failures.

Full textAbstract:
Paper [I] tests the success rate of trades and the returns of the Opening Range Breakout (ORB) strategy. A trader that trades on the ORB strategy seeks to identify large intraday price movements and trades only when the price moves beyond some predetermined threshold. We present an ORB strategy based on normally distributed returns to identify such days and find that our ORB trading strategy result in significantly higher returns than zero as well as an increased success rate in relation to a fair game. The characteristics of such an approach over conventional statistical tests is that it involves the joint distribution of low, high, open and close over a given time horizon. Paper [II] measures the returns of a popular day trading strategy, the Opening Range Breakout strategy (ORB), across volatility states. We calculate the average daily returns of the ORB strategy for each volatility state of the underlying asset when applied on long time series of crude oil and S&P 500 futures contracts. We find an average difference in returns between the highest and the lowest volatility state of around 200 basis points per day for crude oil, and of around 150 basis points per day for the S&P 500. This finding suggests that the success in day trading can depend to a large extent on the volatility of the underlying asset. Paper [III] performs empirical analysis on short-term and long-term Commodity Trading Advisor (CTA) strategies regarding their exposures to unanticipated risk shocks. Previous research documents that CTA strategies offer diversification opportunities during equity market crisis situations when evaluated as a group, but do not separate between short-term and long-term CTA strategies. When separating between short-term and long-term CTA strategies, this paper finds that only short-term CTA strategies provide a significant, and consistent, exposure to unanticipated risk shocks while long-term CTA strategies do not. For the purpose of diversifying a portfolio during equity market crisis situations, this result suggests that an investor should allocate to short-term CTA strategies rather than to long-term CTA strategies.

Previous issue date: 2012-12-10Dans ce travail de recherche nous nous proposons d ?tudier l oeuvre d Anna de Noailles, po?tesse et romanci?re fran?aise qui a publi? ses premi?res po?sies ? la fin du XIX?me si?cle. Notre corpus est constitu? de trois po?mes du recueil L Ombre des Jours, publi? en 1902, ? savoir : Jeunesse, Le R?pit et Renaissance. Initialement, nous avons trait? la mise en contexte sociale et culturelle de la fin du XIX?me et du d?but du XX?me si?cle. Ensuite, nous avons abord? l espace interne de l oeuvre noaillienne qui se manifeste ? travers des paysages de la nature. Nous avons remarqu? que dans celle-ci, il y a une identification avec le moi lyrique. Enfin, nous avons analys? les trois po?mes de notre corpus. Nous soulignons que le manque de critiques et de recherche sur l oeuvre noailliene en France et l absence de recherche sur la po?tesse dans le milieu acad?mique br?silien nous ont motiv?e ? r?aliser cette ?tude. Ce travail a comme objectif mettre en ?vidence la richesse de la po?tique d Anna de Noailles. Dans notre ?tude sur l oeuvre l ombre des jours, nous nous sommes apper?ue que l auteur poss?de son propre style, elle ne cherchait pas ? imiter un mod?le litt?raire particulier ? ses contemporains. Dans son esth?tique, nous avons remarqu? le refuge dans la nature, dans le pass? et aussi une forte ?vocation sensorielle. L univers lyrique de l oeuvre noaillienne est represent? ? travers des paysages bucoliques qui ?voquent des saisons. Malgr? ce retour ? la nature, nous avons d?couvert des ?l?ments que caract?risent la po?sie moderne, comme la luminosit?, la qu?te de l expansion, la superposition des images, entre autres. L espace de l ombre des jours est grandiloquent, la po?tesse mentionne fr?quemment son d?sir d expansion et pour cette raison, nous trouvons dans les po?mes des lieux ouverts, o? le contact direct avec la lumi?re, l air et l eau devient possible. Dans l Ombre des Jours, il est rare qu une r?f?rence ? un lieu clos soit trait?e; si la po?tesse le fait, c est pour exprimer la suspension de la passion

Enfim, analisamos os tr?s poemas do nosso corpus. Ressaltamos que a falta de obras cr?ticas e de pesquisas sobre a obra noailliana na Fran?a e a aus?ncia de pesquisa sobre a poetisa no meio acad?mico brasileiro nos motivou a realizar esse estudo. Com esse trabalho, objetivamos ressaltar a riqueza da po?tica de Anna de Noailles. No nosso estudo sobre a obra l ombre des jours, percebemos que a autora tem o seu estilo pr?prio e n?o busca imitar um modelo liter?rio particular dos seus contempor?neos.

O espa?o da obra l ombre des jours ? grandiloquente, a poetisa frequentemente menciona o seu desejo de expans?o; por essa raz?o encontramos nos poemas ambientes abertos onde ? poss?vel o contato direto com a luz, o ar e a ?gua.

Full textAbstract:
The influence of tricalcium silicate content of cement on concrete durability has long been a topic of discussion in the literature. The objective of this investigation was to determine whether increasing tricalcium silicate content of cement has a negative effect on concrete sulfate durability. Several mill certificates were reviewed to select cements with similar tricalcium aluminate content and variable tricalcium silicate contents. Cements selected for this study were randomly labeled as cements C, D, D2, E, and P.
The following properties were assessed for the as-received cements: Blaine fineness, particle size distribution, chemical oxide content, and mineralogical content. Three different methods were employed to determine the mineralogical composition of the as-received cements: Bogue calculation, internal standard method, and Rietveld refinement analysis. Despite the attempt to select cements with similar composition, it was determined that the as-received cements had compositional differences other than their C3S content. These cements had a variable tricalcium aluminate and alkali content, as well as differences in the amount and form of calcium sulfates. In order to eliminate these variances, doped cements were prepared by increasing the C3S content of the as received cements to 69 % by Bogue calculation.
Durability of as-received cements and doped cements was assessed through several measurements including length change, compressive strength, and phase transformation in sodium sulfate solution. For as-received cements, compressive strength of mortar cubes stored in saturated lime solution was evaluated as well. Semiquantitative x-ray diffraction analysis and scanning electron microscopy observations were performed on mortar bars to evaluate the relative amounts and morphology of the hydrated phases.
It was concluded at the end of this study that cements with high tricalcium silicate content generally have poor durability in sodium sulfate environment. All the cements experienced higher expansion with increased C3S content. High C3S content combinedwith high C3A content was particularly detrimental to mortar resistance to sodium sulfate attack.

Il intervient dans la traçabilité des basses pressions absolues, via la méthode d’expansion continue, et celle des fuites d’hélium, liées aux applications dans le domaine du vide. De plus, nous avons montré que le fluxmètre à pression constante du Laboratoire commun de métrologie (LCM) permettait le raccordement des mesures de micro-débits, sous-domaine de la débitmétrie. Outre les points clés de la conception et la caractérisation métrologique, ce mémoire décrit l’étude de l’expansion continue ainsi que les travaux de comparaison du fluxmètre gazeux à pression constante avec les méthodes de référence employées au LCM, en particulier la méthode de gravimétrie dynamiqueThis dissertation concerns the development and applications of a constant pressure gas flowmeter, the primary reference instrument used by National metrology laboratories to measure very low gas flows. It guarantees the traceability of low absolute pressures, via the continuous expansion method, and that of helium leaks, both related to applications in the field of vacuum. In addition, we have shown that the Laboratoire commun de métrologie (LCM) constant pressure flowmeter is well suited to micro-flow measurements, a sub-field of flow metering. Besides key points of the design and metrological characterization, this document describes the study of the continuous expansion method and work on comparisons of the constant pressure gas flowmeter with reference methods used at LCM, in particular the dynamic gravimetric method

This diploma thesis deal with evaluation of the impact in the scale of uncertaintly stiffness on the tool deviation during grooving process. By the affect of the insufficient stiffness in each parts of the machine, there is presented a mechanical vibration during the cutting process which may cause a damage to the surface of the workpiece, to the tool or to the processing machine. The change of the stiffness is caused in the result of tool wear, impact of setted cutting conditions and many others. In the first part includes teoretical introduction to field of the uncertainty and choosing suitable methods for the solutions. Chosen methods are Monte Carlo and polynomial chaos expansion which are procced in the interface of MATLAB. Both of the methods are primery tested on the simple systems with the indefinited enters of the stiffness. These systems replace the parts of the stiffness characteristics of the each support parts. After that, the model is defined for the turning during the process of grooving with the 3 degrees of freedom. Then the analyses of the uncertainity and also sensibility analyses for uncertainity entering data of the stiffness are carried out again by both methods. At the end are both methods compared in the points of view by the time consuption and also by precission. Judging by gathered data it is clear that the change of the stiffness has significant impact on vibration in all degrees of freedome of the analysed model. As the example a maximum and a minimum calculated deviation of the workpiece stiffness was calculated via methode of Monte Carlo. The biggest impact on the finall vibration of the tool is found by stiffness of the ball screw. The solution was developed for the more stabile cutting process.

Full textAbstract:
The work consists of two parts.
In the first part which is concerned with random walks, we construct the conditional versions of a multidimensional random walk given that it does not leave the Weyl chambers of type C and of type D, respectively, in terms of a Doob h-transform. Furthermore, we prove functional limit theorems for the rescaled random walks. This is an extension of recent work by Eichelsbacher and Koenig who studied the analogous conditioning for the Weyl chamber of type A. Our proof follows recent work by Denisov and Wachtel who used martingale properties and a strong approximation of random walks by Brownian motion. Therefore, we are able to keep minimal moment assumptions. Finally, we present an alternate function that is amenable to an h-transform in the Weyl chamber of type C.
In the second part which is concerned with Brownian motion, we examine the non-exit probability of a multidimensional Brownian motion from a growing truncated Weyl chamber. Different regimes are identified according to the growth speed, ranging from polynomial decay over stretched-exponential to exponential decay. Furthermore we derive associated large deviation principles for the empirical measure of the properly rescaled and transformed Brownian motion as the dimension grows to infinity. Our main tool is an explicit eigenvalue expansion for the transition probabilities before exiting the truncated Weyl chamber.

Full textAbstract:
Intitulée L’oeuvre de la marche : créer dans les pas d’artistes flâneurs - Éléments théoriques pour une cartographie sonore et mouvante des espaces d’ambulation en expansion, notre recherche propose d’interroger la fécondité potentielle de pratiques artistiques plasticiennes qui font du corps actif en marche, l’élément moteur d’espaces de créations transversales à parcourir. Il s’agit d’examiner les enjeux théoriques de ces « dé-marches » artistiques, la marche constituant par excellence un mode de déplacement réputé pour sa lenteur, à une époque où la société impose un rythme accéléré et une occupation effervescente des territoires qui vont à l’encontre de telles pratiques. Notre recherche théorique s’adosse pour ce faire, à notre production artistique personnelle, et un travail de terrain nourri par des entretiens avec nombre d’artistes qui placent le déplacement au cœur de leur création. Selon nous, la représentation élaborée par nos sociétés occidentales concernant l'espace dans lequel nous évoluons a été jusqu’à présent principalement rétinienne mais se révèle de plus en plus définie dans sa dimension sonore. Aussi, proposons-nous d’évaluer sous cet angle, l'intérêt plastique de multiples espaces d’ambulation à travers des thématiques développées par l'acte créatif de la marche : créations paysagères, urbaines, mobiles, en réseaux, en archipels, ou constellations. Notre propos consiste à examiner les paysages dans leur dimension plastique sonore et visuelle et l’usage qu’en font les artistes, témoins sensibles d’une ère de la mobilité, pour construire un devenir des espaces d’ambulation sous forme d’utopies mobilesEntitled The art of walking, creating in the footsteps of artist wanderers - Theoretical elements for sound mapping of moving and expanding ambulation spaces, our research proposes to examine the potential fertility of the practices of visual artists who actively use the body in walking as the motor element of transversal creations that can be explored. It examines the theoretical issues of this artistic practice, walking being a mode of travel known for its slowness, at a time when society imposes an accelerated pace and effervescent occupation of territories that go against such practices. Our theoretical research is backed by a personal artistic production, supported by conversations with many artists whose movement is the heart of their creation. In our view, the representation developed by Western societies of the space in which we operate has been so far mainly visual but proves to be more and more defined through its sound dimension. Therefore, we propose to evaluate through this perspective, the interest of many areas of artistic ambulation around themes developed by the creative act of walking: creative landscape, urbanism, mobility, networks, archipelagos or constellations. Our proposal is to examine the landscapes in their sound and visual dimensions and the way they are used by artists, sensitive witnesses of an era of mobility, to build future spaces of ambulation as mobile utopias

In Chapter I, I examine the Macedonian background of Alexander�s court and his native conception of kingship. Chapter II is a study of the kingship of Egypt. Chapter III deals with the kingship of Babylon and Persia. I then turn to an analysis of Alexander�s policies towards the Persians and the concept of the "kingship of Asia," as this was understood by Alexander. This crucial concept is to be distinguished from the kingship of Persia, a position which Alexander supplanted and replaced with his personal kingship of Asia. In Section II, three chapters are devoted to an analysis of the transformation of Alexander�s court. Chapter IV covers the origin and significance of Alexander�s royal insignia. Chapter V examines the introduction of, and the role played by, Persians and easterners in the king�s court; and Chapter VI the significance of other Persian court offices.

Full textAbstract:
In this thesis we study some portfolio optimization and option pricing problems in market models where the dynamics of one or more risky assets are driven by Lévy processes, and it is divided in four independent parts.
In the first part we study the portfolio optimization problem, for the logarithmic terminal utility and the logarithmic consumption utility, in a multi-defaultable Lévy driven model.
In the second part we introduce a novel technique to price European defaultable claims when the pre-defaultable dynamics of the underlying asset follows an exponential Lévy process.
In the third part we develop a novel methodology to obtain analytical expansions for the prices of European derivatives, under stochastic and/or local volatility models driven by Lévy processes, by analytically expanding the integro-differential operator associated to the pricing problem.
In the fourth part we present an extension of the latter technique which allows for obtaining analytical expansion in option pricing when dealing with path-dependent Asian-style derivatives.In questa tesi studiamo alcuni problemi di portfolio optimization e di option pricing in modelli di mercato dove le dinamiche di uno o più titoli rischiosi sono guidate da processi di Lévy. La tesi é divisa in quattro parti indipendenti. Nella prima parte studiamo il problema di ottimizzare un portafoglio, inteso come massimizzazione di un’utilità logaritmica della ricchezza finale e di un’utilità logaritmica del consumo, in un modello guidato da processi di Lévy e in presenza di fallimenti simultanei. Nella seconda parte introduciamo una nuova tecnica per il prezzaggio di opzioni europee soggette a fallimento, i cui titoli sottostanti seguono dinamiche che prima del fallimento sono rappresentate da processi di Lévy esponenziali. Nella terza parte sviluppiamo un nuovo metodo per ottenere espansioni analitiche per i prezzi di derivati europei, sotto modelli a volatilità stocastica e locale guidati da processi di Lévy, espandendo analiticamente l’operatore integro-differenziale associato al problema di prezzaggio. Nella quarta, e ultima parte, presentiamo un estensione della tecnica precedente che consente di ottenere espansioni analitiche per i prezzi di opzioni asiatiche, ovvero particolari tipi di opzioni il cui payoff dipende da tutta la traiettoria del titolo sottostante.

This retrospective study aims to evaluate the morphological changes produced after and surgically assisted maxillary rapid expansion (ERMAC). A three-dimensional evaluation was performed with CBT and scanning of the intraoral and gingival models at the preoperative (T0) and postoperative (T1 and T2) moments in order to evaluate linear and angular movements with bone and dental changes underlying. The possible morphological alterations of the related structures were evaluated: nasopharynx volume, oropharynx volume in relation to ERMAC. The sample consisted of 15 individuals (8 males and 7 females aged 19 to 54 years) submitted to MRS. In general, ERMAC produced a significant increase in all linear distances of the maxilla. There was a greater expansion of the maxilla in the anterior region than in the posterior one. The ERMAC produced a significant increase of the skeletal dimensions of the maxilla in the transversal direction. In the airways, there was a significant increase in all patients and the greatest effects of ERMAC occurred at the dental level, with the buccal inclination of the first molars and the upper premolars being observed.

In addition to the introduction and conclusion, the body of this thesis is composed of five chapters:analysis of Mahan''''s theory; evaluation of the conditions for Communist China''''s sea power development;Communist China''''s externally-oriented economy and its seas; the expansion of Communist China''''s navy; a look at Communist China''''s sea power expansion by adopting Mahan''''s theory. The paper is sequentially developed by focusing on the two core dimensions of“use of the sea” and“ control of the sea”, and goes on to explain how the two aspects are complementary and mutually supporting. The externally-oriented economy of Communist China will influence all aspects of Communist China''''s economy. In addition, the rise of the leadership in mainland China that favor the expansion of “sea power”will strive to protect the country''''s sea rights, and to establish its regional supremacy by threatening the Asia- Pacific countries. Sea power originated with trade. If Communist China is going to develop its economy through trade, then it must first reform its present economic system. The necessary economic changes will also involve the political system. Since the Communist China is placing economic construction at the core of its long-term national strategy, then the real focus should be the changes to be made in its economic－ political system.

The Enlarged Meeting of the Party Central Military Commission in 1985 marked a drastic shift in China''s threat perception. It stated that the long-anticipated war with the Soviet Union was not likely to occur in the foreseeable future. Thus, People''s Liberation Army needed to switch from preparing to fight ''an early, major and nuclear war'' to a normal peacetime posture. The directive made at that meeting war regarded as a "strategic transformation". It represented an end to the era when the Navy always played a supporting role in the PRC''s military system. According to China''s strategic transformation, the PRC''s naval strategy is from ''coastal defense'' to ''offshore defense'', and upgrades the Navy from a coastal patrol force to a ''definite influence force'' in the Western Pacific region. In the future, the PRC Navy will be threat to the ROC''s sea line of communication and national security. The sword of Damocles hangs high over the territorial waters around the Taiwan. The opportunity of maritime conflict between the PRC and the ROC is very high.The ROC Navy in order to protect international trade against the PRC''s naval invasion or interdiction with force recapitalization. Force recapitalization is crucial for Navy to formulate naval strategy and force structure. This essay attempt to discuss about force recapitalization, and try to speculate force recapitalization objects for the ROC Navy. By combination with force planning, maritime strategy, naval operations, naval strategy, and naval technology, I hope to provide a direction and new way ofthinking for the ROC Navy.

Rooted in its special background and timing, China’s consumer market grows fast, strong and impacts broadly. The intelligence unit of the magazine “The Economist” estimates that would be able to maintain an annual growth rate of 5.5 % until 2030. Moreover, with more of its consumers joining the middle class, a fundamental change in China’s consumer market will happen within next 15 years, and China will become a country that has highest density of high - income population. Staged on such a background, and benefiting from scientific and technological progresses and financial innovations. Several major E - commerce players in China are expanding their cross - field and cross - border mergers and acquisitions at a thunder speed. Amazon, the e - commerce giant in the United States, had already been facing to the way of integrating online and offline channels. By contrast, the new retail advocated by Alibaba in this article is not a new concept out of thin air, but a necessary move to increase its competitive advantage in the Chinese consumer market. Through an in - depth analysis and an approachable presentation, the author wishes to convince the reader that Alibaba’s efforts in Fin Tech are changing and constructing a new ecosystem of consuming finance. With the younger generation who are living an online life all the time becoming the major consumer force in the market, a war without ordnance that is changing its consumption type and methods of China's consumer market is wantonly going on.

Casa do Alecrim’s expansion came out as a suitable alternative to empower Associação Alzheirmer Portugal social impact while granting its own financial sustainability. Its concept was designed to include both Nursing Home and Home Support services. The capacity of the first was established on a best estimation basis –36 to 45 patients –due to the absence of an architectural plan whereas the latter relied on a replication of the existing model –50 patients. Lastly, according to collected estimates, CAPEX was projected at €1,2M and the OPEX was based on the existing costs with the required HR adjustments.

For Casa do Alecrim’s expansion to be implemented, it was necessary to performan extensive financial analysis. Given the defined price range and the need for further investigation regarding Nursing Home’s maximum capacity and Home Support’s occupancy rate, best-case and worst-case scenarios were computed, as well as a final recommendation regarding financing. With this new facility, Associação Alzheimer Portugal will be able not only to increase its cash balance by 10-fold, reaching financial sustainability in other business units and independency from Social Security, but also to enhanceits social impact, expanding its reach to an additional 1.045dementia patients.

The thesis is a study of Chinese investment into Laos. Laos is described in historical, political and economic context and relevant aspects of contemporary Laos life are drawn upon. It examines current projects on the ground including a casino, infrastructure, industry and other development projects, and the impacts of these projects are discussed. It questions whether Chinese behavior in Laos is unique, given the social and economic singularity of Laos, or whether wider implications can be drawn. The methodology included a series of interviews undertaken on the ground as well as an extensive literature review of journals, newspapers and textbooks. The paper concludes by discussing theory, and argues that China is trying to use economic statecraft to translate financial influence into political sway, in order to coerce Laos into allowing China a foothold in a geographically important location. This behavior is visible in other Chinese bi-lateral relationships and therefore the activities of the PRC in Laos are representative of a wider strategy. The Laos elites must try to balance Chinese influence with that of the Western community, Vietnam and Thailand, without allowing China control over sovereign decisions.

The development of financial service industry is getting mature, and the banking in Taiwan can’t make a profit due to over-competition. Recently, the situation of political and economic development to the cross-strait ties becomes stable. It makes many financial sectors want to make a breakthrough and extend their business field in China so that they will refer to China as a main developing market for the banking in Taiwan. Financial Supervisory Commission has begun to loosen the investment limitation for the dealers since 2010, so many financial service industries were eager to develop the career in China from then on. China sets more limitations to the banking in Taiwan, so we should occupy the market share first with financial leasing. Only in this way can we accelerate the pace that we occupy the market share in China, and it will be the foundation of banking business. Thus, the purpose of the research was to investigate the situation of financial leasing in China. SWOT and Five Forces Analysis were used in the research to analyze the possibility of that domestic financial holdings and the banking in Taiwan are engaged in financial leasing in China. The research suggested that the financial service industries in Taiwan operate their business in China via financial leasing. It recommended that we set up our own talent database earlier, because it would enable us to develop the business and the connection of the specialists and experts. Moreover, it also advised that the financial service industries in Taiwan link up Chinese capital banks with foreign capital banks to work together, and that the sites for business should be close to the sites of Taiwanese businessmen''s enterprise.
