Full textAbstract:
This thesis examines virginity as a social construct, contextualizes the relevance of first sex for contemporary youth, and presents a model for reading themes of virginity and first sex in popular media. Through discursive analysis, the central sections of this thesis – Virginity, Femininity, and Masculinity – analyze themes of sexual abstinence across the four books of the Twilight series. Examining contemporary and historical contexts placing gendered value on virginity and virginity loss, this project suggests that virginity narratives reflect whose bodies are considered to be valuable in society and for what purpose. The conclusion argues that virginity narratives are fundamentally colonial narratives, requiring the fantasy of unclaimed spaces, conquerors, and those to be conquered.

Full textAbstract:
Pharmacometrics is widely used in drug development. Models are developed to describe pharmacological measurements with data gathered from a clinical trial. The information can then be applied to, for instance, safely establish dose-response relationships of a substance. Glycated hemoglobin (HbA1c) is a common biomarker used by models within antihyperglycemic drug development, as it reflects the average plasma glucose level over the previous 8-12 weeks. There are five different nonlinear mixed-effects models that describes HbA1c-formation. They use different biomarkers such as mean plasma glucose (MPG), fasting plasma glucose (FPG), fasting plasma insulin (FPI) or a combination of those. The aim of this study was to compare their performances on a population and an individual level using model averaging (MA) and to explore if reduced trial durations and different treatment could affect the outcome. Multiple weighting methods were applied to the MA workflow, such as the Akaike information criterion (AIC), cross-validation (CV) and a bootstrap model averaging method. Results show that in general, models that use MPG to describe HbA1c-formation on a population level could potentially outperform models using other biomarkers, however, models have shown similar performance on individual level. Further studies on the relationship between biomarkers and model performances must be conducted, since it could potentially lay the ground for better individual HbA1c-predictions. It can then be applied in antihyperglycemic drug development and to possibly reduce sample sizes in a clinical trial. With this project, we have illustrated how to perform MA on the aforementioned models, using different biomarkers as well as the difference between model weights on a population and individual level.

Tese de Doutoramento em Design, com a especialização em Design apresentada na Faculdade de Arquitetura da Universidade de Lisboa para obtenção do grau de Doutor.Na transição da sociedade da Terceira Revolução Industrial para a Sociedade do Conhecimento e da Informação, existe necessidade de compreender melhor o mundo. Da sociedade de ativos tangíveis, remanescente da economia de bens materiais e capitalismo industrial, transita-se para a sociedade do conhecimento, com ambição de construção de uma compreensão própria do mundo, que interprete fenómenos promovendo desenvolvimento mais responsável. Uma investigação contribui para o conhecimento quando identifica um problema significante, empreendedor, operacional e mensurável nos seus objetivos. Deve ainda antever crescimento e transformações sustentáveis no tempo e reconhecer possibilidades criativas para atingir objetivos com menor dispêndio e maior rendimento. Estes atributos são pensados em conjunto e interligados, almejando resultados capazes de dialogar e negociar com o real. Estas operações aplicam lógica de organização do pensamento e modelos para reflexão crítica sobre coisas do mundo do ser humano. No domínio da efemeridade, a construção concetual do POP UP delimita o seu ciclo de vida por antecipação, revelando potencial catalisador da prática participativa, onde é pensada como projeto. Estimula participação entre criadores que orientam e utilizadores que experimentam, promovendo ações que estabelecem relações entre intervenientes, acrescentando valor e significado e concretizando a intenção primordial do Design de resolver problemas. A questão em investigação foi formulada do seguinte modo: como é que o conceito POP UP, com as suas qualidades de revelação, contaminação, mobilidade e estratagema, poderá consolidar a sua aceção concetual enquanto modelo catalisador de atuação responsável. Conduziu-se a orientação e boa prática do conceito, desenhando-se um modelo concetual que incentivasse atuação interdisciplinar, criativa e participativa de otimização do processo em Design. Para verificação da hipótese de investigação, estabeleceu-se metodologia de investigação ativa, de observação direta e trabalho de campo, encetando-se trabalho experimental com grupos de amostra para desenvolver o modelo, posteriormente objeto de avaliação em estratégia metodológica de auscultação por painel de especialistas. Estabeleceu-se uma metodologia mista, não intervencionista e intervencionista de base qualitativa. Em sentido restrito, este projeto de investigação defende que o produto produz produtores que produzam o produto, desenhando um modelo de transformação circular sustentador do processo em Design. Em sentido amplo, a concetualização do modelo ambiciona inspirar a inteligência colaborativa por experimentação participativa, propondo novas dinâmicas sociais através dessa prática e promovendo a recuperação dos sentidos comunitário, económico e excecional no quotidiano.
ABSTRACT: In the transition from society of the Third Industrial Revolution to the Society of Knowledge and Information, there is a need to understand the world better. From the society of tangible assets, reminiscent of the economy of material goods and industrial capitalism, one moves to the knowledge society, with the ambition of constructing a proper understanding of the world, which interprets phenomena promoting more responsible development. An investigation contributes to knowledge when it identifies a significant, entrepreneurial, operational and measurable problem in its objectives. It must also foresee sustainable growth and transformation over time and recognize creative possibilities to achieve goals with lower expenditure and higher income. These attributes are thought together and interconnected, aiming at results capable of dialogue and negotiation with the real. These operations apply logic of organization of thought and models for critical reflection on things in the world of the human being. In the field of ephemerality, the conceptual construction of POP UP delimits its life cycle by anticipation, revealing the catalysing potential of participatory practice, where it is thought as a project. It stimulates participation between creators who guide and users who experiment, promoting actions that establish relationships among stakeholders, adding value and meaning and achieving the primary intention of Design to solve problems. The research question was formulated as follows: how the POP UP concept, with its qualities of revelation, contamination, mobility and stratagem, could consolidate its conceptual meaning as a catalyst for responsible action. The orientation and good practice of the concept was guided by designing a conceptual model that would encourage an interdisciplinary, creative and participative action to optimize the Design process. In order to verify the research hypothesis, a methodology was established for active research, direct observation and fieldwork. Experimental work was carried out with sample groups to develop the model, which was subsequently object of evaluation in the methodological strategy of auscultation by expert panel. A mixed, non-interventionist and interventionist qualitative methodology was established. In a narrow sense, this research project argues that the product produces producers who produce the product, designing a model of circular transformation that sustains the process in Design. In a broad sense, the model's ambition is to inspire collaborative intelligence through participatory experimentation, proposing new social dynamics through this practice and promoting the recovery of the community, economic and exceptional senses in everyday life.

xiv, 165 p. ： ill. (some col.)Our current focus on the city core includes reintroducing the mixed-use building. This typology is not without challenges, and arguably none is more pressing than full retail occupancy. This analysis investigates the potential for start-up companies to supplement traditional retail on an interim basis. By documenting the needs and expectations of the start-up and development communities (from multiple perspectives), this study assesses the potential connection between mixed-use and the start-up company. Using a methodology informed by literature and augmented by personal accounts, this analysis reveals that the inclusion of start-up companies in mixed-use projects can present both short- and long-term benefits to ongoing retail difficulties: mixed-use buildings can be an ideal location for start-up firms, including start-up tenants can be economically feasible if certain measures are in place, and a new development model is not needed to connect an emerging business with an existing project.

Full textAbstract:
The Bistable Aerial Platform (BAP) has been developed in order to further enlarge the repertoire of devices available at the microscale. This novel device functions as a switch in that its platform can lock in two positions, up or down. Herein, it will be examined and explained, but a true understanding of its workings requires a better understanding of its compliant constituent parts. The Helico-Kinematic Platform (HKP), which serves as an actuator for the BAP, is currently under investigation by another researcher and will be merely touched upon here. The focus, therefore, will rest on the analysis of the Quadrantal Bistable Mechanism (QBM), the principle component of the BAP. A preliminary pseudo-rigid-body model, an aid for the understanding of compliant mechanisms, will also be examined for the QBM. The models developed for these two devices, the HKP and QBM, can later be combined to form a full model of the Bistable Aerial Platform.

Full textAbstract:
Due to the complexity, multi-scale, and multi-physics nature of the mathematical models for fires, current numerical models require too much computational effort to be useful in design and real-time decision making, especially when dealing with fires over large domains. To reduce the computational time while retaining the complexity of the domain and physics, our research has focused on several reduced-order modeling techniques. Our contributions are improving wildland fire reduced-order models (ROMs), creating new ROM techniques for nonlinear systems, and preserving optimality when discretizing a continuous-time ROM. Currently, proper orthogonal decomposition (POD) is being used to reduce wildland fire-spread models with limited success. We use a technique known as the discrete empirical interpolation method (DEIM) to address the slowness due to the nonlinearity. We create new methods to reduce nonlinear models, such as the Burgers' equation, that perform better than POD over a wider range of input conditions. Further, these ROMs can often be constructed without needing to capture full-order solutions a priori. This significantly reduces the off-line costs associated with creating the ROM. Finally, we investigate methods of time-discretization that preserve the optimality conditions in a certain norm associated with the input to output mapping of a dynamical system. In particular, we are able to show that the Crank-Nicholson method preserves the optimality conditions, but other single-step methods do not. We further clarify the need for these discrete-time ROMs to match at infinity in order to ensure local optimality.Ph. D.

Full textAbstract:
La simulation numérique occupe une part de plus en plus importante dans les phases de conception mais aussi de validation de systèmes innovants. Dans le cadre de la conception d’une chaîne de traction d’un véhicule électrique, la simulation numérique peut par exemple être employée pour choisir une technologie de moteur électrique ou encore pour mettre au point des stratégies de pilotage au regard de critères de décision tels que l’autonomie du véhicule, son coût mais aussi sa performance.Les systèmes devenant de plus en plus complexes, ils requièrent des simulations de plus en plus fines afin d’appréhender au mieux les phénomènes qu’ils mettent en œuvre - par exemple l’étude des pertes fer dans une machine électrique. L’utilisation de simulations 3D permet d’avoir des résultats très précis à l’échelle d’un organe mais ne se prête pas encore aujourd’hui à l’étude de systèmes de grande taille (c’est-à-dire avec beaucoup de degrés de liberté, de nombreux paramètres d’optimisation et plusieurs domaines de la Physique en jeu). En effet, les simulations 3D sont d’autant plus coûteuses en temps de calcul que le modèle à étudier contient de degrés de liberté. C’est pourquoi, depuis quelques années les techniques de réduction de modèles attisent les développements. En effet, elles permettent de garantir un bon compromis entre le temps de calcul et la précision des résultats produits par les modèles réduits.Nous nous intéressons ici à l’utilisation de ces techniques dans un contexte industriel autour de deux axes : - l’étude de phénomènes thermiques (dans les modules d’électronique de puissance) - l’étude de phénomènes électromagnétiques (dans les machines électriques)Numerical simulations are widely used during the design phase of a product but also for the validation of an innovative system. For example, during the conception of an electric vehicle’s powertrain, numerical simulations can be used to select the appropriate electric engine technology or for the development of control strategies taking into account decision criteria such as vehicle’s autonomy, but also its cost and performance.System’s complexity is always increasing, so they require more and more precise simulations in order to better understand the phenomena involved - for example to study iron losses in an electric engine. 3D simulations provide very accurate results to study a body but are still not appropriate today for the study of large scale systems (ie. with many degrees of freedom, many optimization parameters and several areas of Physics). Indeed, 3D simulations computing time cost is directly linked with the number of degrees of freedom. That’s why, in recent years, model order reduction techniques stir developments because they guarantee a good compromise between the computation time and accuracy of results produced by these models.In this study, we are interested in techniques that can be used in an industrial context around two axes: - the study of thermal phenomena (in the power electronics modules) - the study of electromagnetic phenomena (in electric engines)

Pop-up cards are greeting cards that have a three-dimensional representation of an object that, when the card is opened, stands up on its own. Grid-based pop-up cards are the most difficult to design manually due to their complexity and number of pieces that must fit together accurately. In order to simplify the pop-up design and fabrication process, this paper presents a computational system to slice STL models and create an SVG file that can be used to laser cut the pieces required to make a grid-based pop-up model. The computational system inputs a 3D model, slices it, and layers slits on top of these slices to ensure that the result will fit together, creating an easily assembled pop-up card. Initial testing shows that the computational model will successfully slice and layer slits on models made up of fewer triangles but tends to have issues with larger, more complex models. The main area of improvement for the computational model is with slicing time, which can be improved through the utilization of existing slicing algorithms mainly used for 3D printing.

Full textAbstract:
This study investigates the upper ocean circulation along the west Australian coast, based
on recent observations (WOCE ICM6, 1994/96) and numerical output from the 1/6 degree Parallel Ocean
Program model (POP11B 1993/97). Particularly, we identify the source regions of the Leeuwin
Current, quantify its mean and seasonal variability in terms of volume, heat and salt transports,
and examine its heat balance (cooling mechanism). This also leads to further understanding of the
regional circulation associated with the Leeuwin Undercurrent, the Eastern Gyral Current and the
southeast Indian Subtropical Gyre.
The tropical and subtropical sources of the Leeuwin Current are understood from an
online numerical particle tracking. Some of the new findings are the Tropical Indian Ocean source
of the Leeuwin Current (in addition to the Indonesian Throughflow/Pacific); the Eastern Gyral
Current as a recirculation of the South Equatorial Current; the subtropical source of the Leeuwin
Current fed by relatively narrow subsurface-intensified eastward jets in the Subtropical Gyre, which
are also a major source for the Subtropical Water (salinity maximum) as observed in the Leeuwin
Undercurrent along the ICM6 section at 22 degrees S.
The ICM6 current meter array reveals a rich vertical current structure near North West
Cape (22 degrees S). The coastal part of the Leeuwin Current has dominant synoptic variability and
occasionally contains large spikes in its transport time series arising from the passage of tropical
cyclones. On the mean, it is weaker and shallower compared to further downstream, and it only
transports Tropical Water, of a variable content. The Leeuwin Undercurrent carries Subtropical
Water, South Indian Central Water and Antarctic Intermediate Water equatorward between
150/250 to 500/750 m. There is a poleward flow just below the undercurrent which advects a
mixed Intermediate Water, partially associated with outflows from the Red Sea and Persian Gulf.
Narrow bottom-intensified currents are also observed.
The 5-year mean model Leeuwin Current is a year-round poleward flow between 22 degrees S and
34 degrees S. It progressively deepens, from 150 to 300 m depth. Latitudinal variations in its volume
transport are a response to lateral inflows/outflows. It has double the transport at 34 degrees S (-2.2 Sv)
compared to at 22 degrees S (-1.2 Sv). These model estimates, however, may underestimate the transport
of the Leeuwin Current by 50%. Along its path, the current becomes cooler (6 degrees C), saltier (0.6 psu)
and denser (2 kg m -3). At seasonal scales, a stronger poleward flow in May-June advects the
warmest and freshest waters along the west Australian coast. This advection is apparently spun up
by the arrival of a poleward Kelvin wave in April, and reinforced by a minimum in the equatorward
wind stress during July.
In the model heat balance, the Leeuwin Current is significantly cooled by the eddy heat
flux divergence (4 degrees C out of 6 degrees C), associated with mechanisms operating at submonthly time scales.
However, exactly which mechanisms it is not yet clear. Air-sea fluxes only account for ~30% of the
cooling and seasonal rectification is negligible. The eddy heat divergence, originating over a narrow
region along the outer edge of the Leeuwin Current, is responsible for a considerable warming of a
vast area of the adjacent ocean interior, which is then associated with strong heat losses to the
atmosphere. The model westward eddy heat flux estimates are considerably larger than those
associated with long lived warm core eddies detaching from the Leeuwin Current and moving
offshore. This suggests that these mesoscale features are not the main mechanism responsible for
the cooling of the Leeuwin Current. We suspect instead that short lived warm core eddies might
play an important role.

Full textAbstract:
Background: The main aim of the studies in this thesis is to provide insights into the neonatal phencyclidine (PCP) induced deficits in male and female rats as a neurodevelopmental animal model of schizophrenia. Methods: Both male and female rats were treated with neonatal PCP on postnatal days (PNDs) 7,9 and 11 or vehicle, followed by weaning on PND 21-22. The rats were then tested in behavioural paradigms such as novel object recognition, spatial memory and social interaction in their adolescent and adult stages and were also tested with acute treatment of typical and atypical antipsychotic agents. Results: Neonatal PCP treatment (10 & 20 mg/kg in males and 10 mg/kg in females; once a day for 3 days on PND 7,9 and 11) caused novel object recognition and spatial memory impairment in male and female rats both in the adolescent (PND35-56) and in the adult stages (PND>56) (chapter 2) and robust deficits in social interaction behaviours in the adolescent stage. The SI deficits were observed in adulthood in female but not in male rats thereby establishing a sex-specific social behavioural deficit (chapter 3). The object memory and social interaction deficits induced by neonatal PCP treatment were reversed following acute risperidone but not haloperidol. Finally, the temporal profile of this treatment regime was investigated and the male and female animals were tested on PND 190 and PND 365. The animals did not have any challenge dose of PCP during their testing stage. The result showed that there was significant deficit in object and spatial recognition memory in both male and female animals at both time points, thereby establishing enduring deficits. Conclusion: Given the heterogeneity of the schizophrenic disorder and its complex aetiology, it is understandably difficult to find animal models that completely mimic most or all of the symptoms associated with the disorder. However, data from the studies in this thesis support the use of neonatal PCP as a valid animal model of cognitive and negative symptoms, and explores the effect of antipsychotics in understanding the model. Also, in light of the efficacy of neonatal PCP to produce robust object, spatial memory and social interaction deficits in rats, it appears that this model may be a useful tool to investigate the potential of novel therapeutic candidates that may help improve therapy and understand the illness.

Full textAbstract:
Populärmusik svämmar över av harmoniska förlopp hämtade ur både folk- och konstmusik, vilket har föranlett att inget samförstånd finns kring huruvida sådan musik bör analyseras. Det har emellertid gjorts analyser av angloamerikansk populärmusik utifrån neo-Riemanniansk teori, där musikanalytikerna menat att detta förfarande haft god förklaringskraft. Ambitionen med denna studie var att bidra till neo-Riemanniansk teoriutveckling. Detta genom att analysera ackordprogressioner från fyra svenska populärmusikaliska verk, där vedertagna analysverktyg, som exempelvis funktionsanalys, inte antogs vara fruktbara. Analyserna av ackordprogressionerna gjordes med utgångspunkt i neo-Riemanniansk teori, därefter tonalt (funktionsanalys) och modalt. Detta trefaldiga tillvägagångssätt ansågs vara relevant för att visa på olika analysmetoders fruktbarhet. Resultatet visade att neo-Riemanniansk teori enbart kan förklara förhållandet mellan två konsonanta treklanger, dock alla ackordförhållanden i denna analys, men inte ett musikstycke i sin helhet. Vid analys av låtar med septimackord hade ett neo-Riemannianskt förfarande inte god förklaringskraft, där i stället funktionsanalys kunde förklara ackordprogressioner bättre. Dessa två analysverktyg kompletterade varandra, medan musikexemplen var svåra att förklara modalt.

Full textAbstract:
A comprehensive failure detection model is proposed to detect service failures in asynchronous distributed systems. The proposed model takes advantage of P2P technology to provide required functionality. When compared to similar studies in failure detection, the presented failure detection model is more autonomous in resolving service dependencies, embodies more flexibility in providing different failure detection functions (like unreliable failure detectors, membership services) and offers more security. A failure detection library is developed using JXTA P2P framework to show realization of such a model.

Full textAbstract:
Fundação de Amparo à Pesquisa do Estado do Rio de JaneiroA velocidade do som é uma propriedade que vem sendo cada vez mais utilizada em diferentes áreas tecnológicas. Além disso, a velocidade do som é uma propriedade termodinâmica que está associada a outras propriedades do meio como a compressibilidade isentrópica e isotérmica, entre outras. Neste contexto, muitos estudos foram realizados a fim de obter modelos precisos que possam representar fielmente a velocidade do som, sendo observados desvios absolutos médios entre 0,13 e 24,8%. Neste trabalho, um banco de dados de velocidade do som e massa específica à pressão atmosférica de n-alcanos, alcanos ramificados, n-alcenos, aromáticos, alcoóis, éteres e ésteres, foram compilados da literatura aberta. Utilizando estes dados e baseando-se no modelo de Wada por contribuição de grupo recentemente proposto, foi desenvolvido um novo modelo por contribuição atômica para predizer a velocidade do som de todas as famílias dos compostos investigados neste trabalho. É mostrado que o modelo proposto é capaz de prever a velocidade do som para os compostos destas famílias com desvios próximos da incerteza experimental calculada a partir de diferentes dados da literatura. Este trabalho também discute o efeito da ramificação das cadeias na constante Wada, ressaltando a importância de novas medições para este tipo de compostos. Além disso, observou-se que a literatura necessita de mais dados experimentais de velocidade do som, à pressão atmosférica e diferentes temperaturas para substâncias puras presentes em biodiesel e bio-óleo de pirólise rápida. Neste contexto, o presente trabalho fornece novos dados experimentais de velocidade do som e massa específica de cinco ésteres metílicos de ácidos graxos, também conhecidos como FAMEs, (caprilato de metila, caprato de metila, palmitato de metila, estearato de metila e linoleato de metila), e sete componentes puros presentes em bio-óleo de pirólise à pressão atmosférica, de vários fenóis (fenol, o-, m- e p-cresol), dois éteres fenólicos (2-metoxifenol e eugenol) e um éster fenólico (salicilato de metila), a temperaturas de (288,15-343,15) K. O modelo preditivo de Wada atômico foi utilizado para calcular a velocidade do som dos FAMEs estudados neste trabalho, e os desvios foram comparados com o modelo de Wada por contribuição de grupo. O modelo atômico de Wada foi utilizado para prever a velocidade do som dos componentes puros presentes no bio-óleo de pirólise rápida experimentalmente estudados nesta dissertação. Além disso, os dados de massa específica e velocidade de som foram correlacionados com o modelo de Prigogine-Flory-Patterson (PFP). As propriedades foram bem representadas pelo modelo PFP, no entanto, para a velocidade do som o modelo apresenta desvios sistemáticos na dependência com a temperatura. O desempenho do modelo preditivo de Wada atômico foi considerado satisfatório, devido os desvios observados serem compatíveis ou até menores do que os desvios típicos obtidos na literatura com outros modelos correlativos para o cálculo da velocidade do som de outras substâncias
Speed of sound is a property that is being increasingly used in different technological areas. Furthermore, the speed of sound is a thermodynamic property which is associated with other properties of the medium, such as isentropic and isothermal compressibility, among others. In this context, many studies were carried out to obtain accurate models that can faithfully represent the speed of sound, with average absolute deviations between 0.13 and 24.8%. In this work a database of speed of sound and density at atmospheric pressure for n-alkanes, branched alkanes, n-alkenes, aromatics, alcohols, ethers and esters were collected from the open literature. Using these data a Wada group contribution model recently proposed was used as basis for the development of a new atomic contribution model to predict speed of sound for all families of compounds investigated in this work. It is shown that the proposed model is able to predict the speed of sound for compounds of these families with deviations close to the experimental reproducibility. This work also discusses the effect of branching on the Wadas constant, pointing out the importance of new measurements for this type of compounds. It was also observed that the literature needs more experimental data of speed of sound at atmospheric pressure and different temperature for pure compounds present in biodiesel and fast pyrolysis bio-oil. In this context, this work provides new experimental data of speed of sound and density for five Fatty Acid Methyl Esters, also know FAMEs, (Methyl Caprylate, Methyl Caprate, Methyl Palmitate, Methyl Stearate and Methyl Linoleate), and seven pure components of pyrolysis bio-oil at atmospheric pressure for several phenols (phenol, o-, m- and p-cresol), two phenolic ethers (2-methoxyphenol and eugenol) and one phenolic ester (methyl salicylate) at temperatures ranging from (288.15 to 343.15) K. The predictive atomic Wada model was used to calculate speed of sound of FAMEs studied in this work, and the deviations were compared with group contribution Wada model. An extension of atomic Wada model was used to predict the speed of sound of pure compounds of fast pyrolysis bio-oil experimentally studied in this thesis. Furthermore, data of densities and speed of sound are correlated with the Prigogine-Flory-Patterson (PFP) model. The properties are well described by the PFP model, however the model presents a systematical deviation on the temperature dependency of the speed of sound. The performance of the predictive atomic Wada model was very satisfactory because its deviations are comparable to, or better than, those obtained in the literature with other models

Full textAbstract:
This dissertation works towards the larger objective of identifying and assessing the key features of molecular structure that lead to desired polymer processing performance with an ultimate goal of being able to tailor-make specific macromolecules that yield the desired processing response. A series of eight well-characterized, high-density polyethylene (HDPE) resins, with varying degrees of sparse long chain branching (LCB) content, is used to study the effect of both LCB content and distribution on the rheological and commercial processing response using the Pom-pom constitutive relationship. A flow instability known as ductile failure in extensional flow required the development a novel technique known as encapsulation in order to carry out shear-free rheological characterization.
Ductile failure prevents the rheological measurement of transient stress growth at higher strains for certain strain-hardening materials. This reduces the accuracy of nonlinear parameters for constitutive equations fit from transient stress growth data, as well as their effectiveness in modeling extensionally driven processes such as film casting. An experimental technique to overcome ductile failure called encapsulation in which the material that undergoes ductile failure is surrounded by a resin that readily deforms homogeneously at higher strains is introduced. A simple parallel model is shown to calculate the viscosity of the core material.
The effect of sparse long chain branching, LCB, on the film-casting process is analyzed at various drawdown ratios. A full rheological characterization in both shear and shear-free flows is also presented. At low drawdown ratios, the low-density polyethylenes, LDPE, exhibited the least degree of necking at distances less than the HDPE frostline. The sparsely-branched HDPE resins films had similar final film-widths that were larger than those of the linear HDPE. As the drawdown ratio was increased, film width profiles separated based on branching level. Small amounts of LCB were found to reduce the amount of necking at intermediate drawdown ratios. At higher drawdown ratios, the sparsely-branched HDPE resins of lower LCB had content film-widths that mimicked that of the linear HDPE, while the sparsely-branched HDPE resins of higher LCB content retained a larger film width. Molecular structural analysis via the Pom-pom constitutive model suggested that branching that was distributed across a larger range of backbone lengths serve to improve resistance to necking. As the drawdown ratio increased, the length of the backbones dominating the response decreased, so that the linear chains were controlling the necking behavior of the sparsely-branched resins of lower LCB content while remaining in branched regime for higher LCB content HDPEs. Other processing variables such as shear viscosity magnitude, extrudate swell, and non-isothermal processing conditions were eliminated as contributing factors to the differences in the film width profile.
The effect of sparse long chain branching, LCB, on the shear step-strain relaxation modulus is analyzed using a series of eight well-characterized, high-density polyethylene (HDPE) resins. The motivation for this work is in assessing the ability of step-strain flows to provide specific information about a material's branching architecture. Fundamental to this goal is proving the validity of relaxation moduli data at times shorter than the onset of time-strain separability. Strains of 1% to 1250% are imposed on materials with LCB content ranging from zero to 3.33 LCB per 10,000 carbon atoms. All materials are observed to obey time-strain separation beyond some characteristic time, Ï k. The presence of LCB is observed to increase the value of Ï k relative to the linear resin. Furthermore, the amount of LCB content is seen to correlate positively with increasing Ï k. The behavior of the relaxation modulus at times shorter than Ï k is investigated by an analysis of the enhancement seen in the linear relaxation modulus, G0(t), as a function of strain and LCB content. This enhancement is seen to 1) increase with increasing strain in all resins, 2) be significantly larger in the sparsely-branched HDPE resins relative to the linear HDPE resin, and 3) increase in magnitude with increasing LCB content. The shape and smoothness of the damping function is investigated to rule out the presence of wall-slip and material rupture during testing. The finite rise time to impose the desired strain is carefully monitored and compared to the Rouse relaxation time of the linear HDPE resins studied. Sparse LCB is found to increase the magnitude of the relaxation modulus at short times relative to the linear resin. It is shown that these differences are due to variations in the material architecture, specifically LCB content, and not because of mechanical anomalies.Ph. D.

This thesis describes several approaches for stabilizing POD-ROMs
(that is, reduced order models based on basis functions derived from the proper
orthogonal decomposition) for both the CDR (convection-diffusion-reaction)
equation and the NSEs (Navier-Stokes equations). Stabilization is necessary
because standard POD-ROMs of convection-dominated problems usually display
numerical instabilities.
The first stabilized ROM investigated is a streamline-upwind
Petrov-Galerkin ROM (SUPG-ROM). I prove error estimates for the SUPG-ROM and
derive optimal scalings for the stabilization parameter. I test the SUPG-ROM
with the optimal parameter in the numerical simulation of a convection-dominated
CDR problem. The SUPG-ROM yields more accurate results than the standard
Galerkin ROM (G-ROM) by eliminating the inherent numerical artifacts (noise) in
the data and dampening spurious oscillations.
I next propose two regularized ROMs (Reg-ROMs) based on ideas from large
eddy simulation and turbulence theory: the Leray ROM (L-ROM) and the
evolve-then-filter ROM (EF-ROM). Both Reg-ROMs use explicit POD spatial
filtering to regularize (smooth) some of the terms in the standard G-ROM. I
propose two different POD spatial filters: one based on the POD projection and a
novel POD differential filter. These two new Reg-ROMs and the two spatial
filters are investigated in the numerical simulation of the three-dimensional
flow past a circular cylinder problem at Re = 100. The numerical results
show that EF-ROM-DF is the most accurate Reg-ROM and filter combination and the
differential filter generally yields better results than the projection filter.
The Reg-ROMs perform significantly better than the standard G-ROM and decrease
the CPU time (compared against the direct numerical simulation) by orders of
magnitude (from about four days to four minutes).Ph. D.

Full textAbstract:
With this research, we work towards the overall objective of customizing polymer molecules in terms of their molecular structure to optimize processing performance. The work includes analysis of the rheology in shear and shear-free flows for sparsely long-chain branched, LCB, polyethylene, PE, resins; determination of the consistency of the molecular based constitutive model, the pom-pom model; for these flows, and evaluation of the same PE resins in film-casting. As we progress towards molecular systems with defined molecular structural characteristics, we transition from a linear low density polyethylene, LLDPE, based series of PE resins to a high density polyethylene, HDPE, based series of PE resins, each with materials of varying degrees of sparse LCB.
Evaluation of the shear step-strain rheology for the series of LLDPE-based PE resins allows for the assessment of any inadequacies associated with the step-strain experiments and the ability of the K-BKZ analog of the pom-pom constitutive model to predict step-strain rheological behavior. Finite rise time and wall slip are addressed to ensure the accuracy of the experimental step-strain measurements and eliminated as factors contributing to the stress relaxation moduli response. Analysis of the K-BKZ analog of the pom-pom constitutive model includes comparisons between experimental stress relaxation moduli and predictions from the model using pom-pom model parameters determined from extensional rheology. The results show inconsistencies in the model predictions, where the predictions fail to capture the short time behavior and accurately dampen at larger strains. Pom-pom model parameters are determined using the K-BKZ analog of the pom-pom constitutive model and fitting the stress relaxation moduli. These results are qualitatively consistent indicating that branching occurs on the longest backbone segments, but the values appear to be unrealistic with respect to the molecular theory.
Analysis of film-width reduction or necking during film-casting for the series of LLDPE-based resins determines whether uniaxial extensional rheological characteristics, in particular strain-hardening, that are a result of LCB influence the film-necking properties. At the lowest drawdown ratio necking is observed to be reduced with increasing LCB, and thus strain-hardening characteristics. At the higher drawdown ratios it is observed that LCB no longer reduces necking and the curves merge to the results found for linear PE, except in the case of LDPE, which shows reduced necking at all drawdown ratios. Furthermore, comparisons of film necking are also made to separate the effects of molecular weight distribution, MWD, and LCB. The results indicate that both broadening the MWD and the addition of sparse LCB reduce the degree of necking observed. It is established that film necking is more significantly reduced by LCB than by broadening the MWD. Analysis of the uniaxial extensional and dynamic shear rheology with the pom-pom constitutive model reveals that a distribution of branches along shorter relaxation time modes is important in reducing necking at higher drawdown ratios. Factors such as shear viscosity effects, extrudate swell, and non-isothermal behavior were eliminated as contributing factors because of the similar shear viscosity curves, N1 curves, and activation energies among the sparsely LCB PE resins.
The same experimental concepts have been extended to the series of HDPE-based resins, but the lack of adequate uniaxial extensional data prevents a thorough analysis with respect to uniaxial extensional characteristics. Regardless, in the context of step-strain rheology, the results were found to be similar with those of the LLDPE-based series of resins, where a distinctive shape at short times was observed for any of the PE resins possessing some level of LCB that was not apparent in the linear PE resins. Film-casting revealed similar results to those of the LLDPE-based materials as well, but a broader spectrum of drawdown ratios revealed greater insight into how the distribution of branching controls the film-casting response. At low drawdown ratios all materials exhibit the same necking behavior. At intermediate drawdown ratios separation occurs where the linear PE resins experiences the most drastic necking, the sparsely LCB PE resins show reduced necking, and the LDPE shows an even greater reduction in necking. Progression then to the higher drawdown ratios results in similar necking behavior for the linear and sparsely LCB PE resins and greatly reduced necking for the LDPE. These results support the idea that to reduce necking the backbone segments that dominate the film-casting behavior must contain some level of LCB.Ph. D.

Previous issue date: 2008-10-30This research focuses on raise the discussion of existance tourism policies in Rio Grande do Norte and its contributions to the integration of local communities in the coastal tourist activity. Guided by the background of the neoliberalism and its influence on the model of tourism development adopted in Rio Grande do Norte. For that, were surveyed the concrete realities of coastal localities of the municipalities of Cear?-Mirim, Extremoz, Parnamirim and N?sia Floresta covered by Prodetur-RN I and II, by being part of the tourist portion of the state that have received domestic and international investment and, because are located in the geographical area of the Potiguar capital, Natal. We interviewed the municipal managers and the residents of local communities who live in municipalities more than ten years. Also, was raised a discussion on the role of the state as the main agent of public policies and hegemonic facilitator in the attraction of domestic and foreign investments, with the main scenario the neoliberal model of economic development. Here discuss ways and strategies of socio-political organization of local communities, with regard to the inclusion in the tourist and, pointing to the critical development model in question and signaling other concepts of development model, such as local basis, for example. By the ending of the research, was concluded that the model of development of the tourism in the Rio Grande do Norte is reflected of the way of life of the society, that the communities live in precarious conditions and that the way of inclusion in the tourism is almost incipient. Also, it was possible to detect the inexistence of public politics of tourism that promoted the planning of the tourist activity, as well as, the inclusion of the communities in the decision processes and that, searched the development on the basis of the principles of sustainable and local autonomy

Full textAbstract:
The topic of this dissertation is the anatomical, psychological, and cultural examination of a human face in order to effectively construct an anatomy-driven 3D virtual face customization and action model. In order to gain a broad perspective of all aspects of a face, theories and methodology from the fields of art, engineering, anatomy, psychology, and cultural studies have been analyzed and implemented. The computer generated facial customization and action model were designed based on the collected data. Using this customization system, culturally-specific attractive face in Korean popular culture, “kot-mi-nam (flower-like beautiful guy),” was modeled and analyzed as a case study. The “kot-mi-nam” phenomenon is overviewed in textual, visual, and contextual aspects, which reveals the gender- and sexuality-fluidity of its masculinity. The analysis and the actual development of the model organically co-construct each other requiring an interwoven process. Chapter 1 introduces anatomical studies of a human face, psychological theories of face recognition and an attractive face, and state-of-the-art face construction projects in the various fields. Chapter 2 and 3 present the Bezier curve-based 3D facial customization (BCFC) and Multi-layered Facial Action Model (MFAF) based on the analysis of human anatomy, to achieve a cost-effective yet realistic quality of facial animation without using 3D scanned data. In the experiments, results for the facial customization for gender, race, fat, and age showed that BCFC achieved enhanced performance of 25.20% compared to existing program Facegen , and 44.12% compared to Facial Studio. The experimental results also proved the realistic quality and effectiveness of MFAM compared with blend shape technique by enhancing 2.87% and 0.03% of facial area for happiness and anger expressions per second, respectively. In Chapter 4, according to the analysis based on BCFC, the 3D face of an average kot-mi-nam is close to gender neutral (male: 50.38%, female: 49.62%), and Caucasian (66.42-66.40%). Culturally-specific images can be misinterpreted in different cultures, due to their different languages, histories, and contexts. This research demonstrates that facial images can be affected by the cultural tastes of the makers and can also be interpreted differently by viewers in different cultures.

Full textAbstract:
Parallel Distributed Processing (PDP) modelling has simulated developmental learning across a range of domains such as reading (e.g. Seidenberg & McClelland,1989) or Semantics (e.g. Rogers et al. 2004). However aside from two notable exceptions (Plaut, 1996; Welbourne & Lambon Ralph, 2005b) modelling research has not addressed the simulation of relearning during spontaneous recovery or rehabilitation after brain damage, and no research has considered the effect of the learning environment. This thesis used an established PDP model of semantic memory (Rogers et al., 2004) to simulate the influence of the learning environment. A novel quantitative measure (called representational economy) was developed to monitor efficiency during learning. Developmental learning is considered to be multimodal (e.g. Gogate et al., 2000) whereas rehabilitation is normally carried out through therapy sessions employing unimodal learning tasks (Best & Nickels, 2000). This thesis hoped to discover whether multimodal rehabilitation may be more efficient (as suggested by Howard et al., 1985). Three sets of simulations were conducted: The first set contrasted multimodal and unimodal learning in development and recovery, and tested internal representations for robustness to damage finding multimodal learning to be more efficient in all cases. The second set looked at whether this multimodal advantage could be approximated by reordering unimodal tasks at the item level. Findings indicated that the multimodal advantage is dependent upon simultaneous item presentation across multiple modalities. The third set of simulations contrasted multimodal and unimodal environments during rehabilitation while manipulating background spontaneous recovery, therapy set size and damage severity finding a multimodal advantage for all conditions of rehabilitation. The thesis findings suggest PDP models may be well-suited to predicting the effects of rehabilitation, and that clinical exploration of multimodal learning environments may yield substantial benefits in patient-related work.

Målet med detta examensarbete har varit att modellera och implementera ett system för att generera medlemskort för idrottsföreningar på uppdrag av Express-Bild AB. Genom deras webbsida vill företaget att man för en förening ska kunna skapa ett medlemskort. En medlem i föreningen ska sedan kunna ladda ner och visa sitt kort i Androidenheten. När kortet visas i mobilen ska det gå att tilta bilden då Androidenhetens position ändras från ett vertikalt läge till ett horisontellt. I samband med att kortet visas i ett vertikalt läge vill företaget att erbjudanden om rabatter och liknande ska visas i samma vy. Skapade kort ska även kunna administreras på sidan. För att åstadkomma detta har tre subsystem identifierats: Ett system för att skapa en mall för korten, ett för att ladda upp viktiga komponenter för korten och ett för att skapa, ladda ner och visa de individuella korten till enheten. Modeller för systemen upprättades i UML för att öka förståelsen av, och insikten i systemens uppbyggnad och funktion. Utifrån modellerna gjordes senare implementationen av systemen. Resultatet av arbetet blev ett system som uppfyllde de flesta av de krav som Express-Bild önskade se uppfyllda. Det enda kravet som inte uppfylldes var att kunna visa erbjudanden om rabatter i medlemskortets vy.The goal with this bachelor thesis has been to model and implement a system for generating membership cards for sports associations on behalf of Express-Bild AB. By using their webpage, the company wants a privileged user of an association to be able to create a membership card for the association. A member of the association should then be able to download and view the card in his android device. When the card is displayed in the device, it should be posible to rotate the card when the device is being tilted. When the card is displayed in a vertical position, should also offers about discounts be displayed in the same view. The possiblity to administrate these cards should exists on the webpage. To accomplish this, three subsystems has been indentified: One system for the creation of a card template, one for uploading important resourdces for the card, and one for creating, downloading and displaying the individual membership card to the device. Models for these systems were established in UML to increase the understanding, and the insight of the systems structure and functionality. These models were later used when implementing the systems. The result of the thesis was a system that fulfilled most of the requirements that Express-Bild had. The only requirement that was not implemented was the one about displaying offers in the membership card view.

Die Entwicklung von verzweigten Blechstrukturen, die mit Hilfe der innovativen Verfahren Spaltprofilieren und Spaltbiegen hergestellt werden, erfordert eine Erweiterung des verwendeten Produktentwicklungsansatzes. Im Sonderforschungsbereich 666 wurde dafür der Algorithmen-basierte Produktentwicklungsprozess eingeführt. Im Unterschied zu etablierten Produktentwicklungsprozessen, werden mathematische Optimierungsalgorithmen mit Randbedingungen aus den formalisierten Anforderungen wie Bauraumrestriktionen oder Lasten verwendet, um optimierte verzweigte Blechstrukturen zu entwickeln. Da in der mathematischen Optimierung nicht alle Informationen aus der Fertigung berücksichtigt werden können, müssen die optimierten verzweigten Blechstrukturen fertigungsgerecht optimiert werden. Dazu wird in diesem Beitrag zunächst ein Fertigungsrestriktionsmodell eingeführt. Basierend auf den gewonnen Erkenntnissen aus dem Modell wird dann ein Ansatz zur teilautomatisierten fertigungsorientierten Optimierung von verzweigten Blechstrukturen eingeführt und anhand eines Beispiels validiert.

Orthogonal Decomposition (POD), Group POD and the Discrete Empirical Interpolation
Method (DEIM), is studied. This study is facilitated by examination of several common
ODE solvers. Embedded in this process, some results on the structure of the POD basis and
an alternative algorithm to compute the POD subspace are presented. Various numerical
studies are conducted to compare the different methods and the to study the interaction of
the spatial discretization on the ROM through the basis functions. Moreover, the results are
used to investigate the impact of Reduced Order Models (ROM) on Optimal Control Problems.
To this end, the ROM is embedded in a Trust Region Framework and the convergence
results of Arian et al. (2000) is extended to POD-DEIM. Based on the convergence theorem
and the results of the numerical studies, the emphasis is on implementation strategies for
numerical speedup.Master of Science

Model order reduction is necessary even in a time where the parallel processing is usual in almost any personal computer. The recent Model Reduction Methods are useful tools nowadays on reducing the problem processing. This work intends to describe a combination between POD (Proper Orthogonal Decomposition) and Ritz vectors that achieve an efficient Galerkin projection that changes during the processing, comparing the development of the error and the convergence rate between the full space and the projection space, in addition to check the stability of the projection space, leading to an adaptive model order reduction for nonlinear dynamical problems more efficient. This model reduction is supported by a secant formulation, which is updated by BFGS (Broyden - Fletcher - Goldfarb - Shanno) method to accelerate convergence of the model, and a tangent formulation to correct the projection space. Furthermore, this research shows that this method permits a correction of the reduced model at low cost, especially when the classical POD is no more efficient to represent accurately the solution.A Redução de ordem de modelo é necessária, mesmo em uma época onde o processamento paralelo é usado em praticamente qualquer computador pessoal. Os recentes métodos de redução de modelo são ferramentas úteis nos dias de hoje para a redução de processamento de um problema. Este trabalho pretende descrever uma combinação entre POD (Proper Orthogonal Decomposition) e vetores de Ritz para uma projecção de Galerkin eficiente que sofre alterações durante o processamento, comparando o desenvolvimento do erro e a taxa de convergência entre o espaço total e o espaço de projeção, além da verificação de estabilidade do espaço de projeção, levando a uma redução de ordem do modelo adaptativo mais eficiente para problemas dinâmicos não-lineares. Esta redução de modelo é assistida por uma formulação secante, que é atualizado pela formula de BFGS (Broyden - Fletcher- Goldfarb - Shanno) com o intuito de acelerar a convergência do modelo, e uma formulação tangente para a correção do espaço de projeção. Além disso, esta pesquisa mostra que este método permite a correção do modelo reduzido com baixo custo, especialmente quando o clássico POD não é mais eficiente para representar com precisão a solução.

O processo de desenvolvimento de produtos (PDP) é formado por um conjunto de atividades organizadas e interativas com o propósito de se planejar, desenvolver e fabricar um produto que seja técnico e economicamente viável, além de ser atrativo e atender, quando possível, todas as expectativas dos usuários. Para que tais atividades sejam realizadas e concluídas faz-se o uso de ferramentas de auxílio ao PDP. Entre estas ferramentas estão os protótipos virtuais e os protótipos físicos. A utilização de protótipos virtuais e físicos no PDP traz maturidade ao projeto, reduz as incertezas, e auxilia na conservação do fluxo de informação durante todo projeto, desenvolvimento, implementação e operação da unidade fabril. Desta forma diferentes protótipos são utilizados para diferentes necessidades, de modo que o desenvolvimento do produto seja concluído e, em paralelo, se inicie o projeto do processo de fabricação. Esta tese apresenta o desenvolvimento de um modelo de referência específico para o processo de desenvolvimento do produto automotivo, denominado de PDP-Automotivo. A partir deste modelo de referência, um conjunto de diretrizes para a seleção de protótipos virtuais e físicos é proposto. O PDP-Automotivo foi validado por meio de uma pesquisa de campo envolvendo profissionais pertencentes à montadoras, autopeças e empresas de projeto automotivo. As diretrizes também foram analisadas e validadas por profissionais atuantes no setor automotivo.The product development process (PDP) consists of a set of organized and interactive activities aiming to plan, develop and manufacture a technically and economically feasible product. Moreover, this product is intended to be attractive and, when possible, meet all users expectations. PDP-aiding tools, such as virtual prototypes and physical prototypes, are used in order to perform and complete these activities. The use of virtual prototypes and physical prototypes in PDP brings maturity to the design, reduces uncertainties and helps to maintain the information flow during the design, development, implementation and operation of the manufacturing unit. Therefore, different prototypes are used to meet distinct needs allowing the achievement of the products development process simultaneously to the start of the manufacturing process design. This doctoral study presents the development of a reference model specific for the automotive product development process, named Automotive PDP. A set of guidelines for the selection of virtual and physical prototypes is proposed from this reference model. Automotive PDP was validated by a field research involving professional members from automakers, auto parts and automotive design companies. The guidelines were also analyzed and validated by professional individuals from the automotive sector.

Full textAbstract:
Polyoxometalates (POMs) are a rapidly growing class of metal-oxygen-cluster anions. The properties of POMs can be modified by altering the POMs chemical composition and structure. Due to low cost, commercial availability, and synthetic tractability POMs have found application in various fields of chemistry and technology. POMs are reusable and thermally stable to oxidative conditions, making them an attractive alternative to chlorine for the delignification of wood pulp. The research addressed in this dissertation deals with detailed kinetic and mechanistic studies of K₅[SiVW₁₁O₄₀]·12H₂O, a POM used in the delignification of wood pulp, oxidation of phenolic lignin model compounds and milled wood lignin (MWL). Results from lignin model studies suggest an overall second-order reaction rate; first order with respect to both POM and phenolic substrate. It was observed that electron-transfer from neutral phenols was slower than that from the corresponding phenoxide anions. Hammett studies revealed the reaction involved the formation of an electron-deficient radical intermediate where the rate-determining step is electron transfer from a neutral substrate. The structure of the substituted phenol, in terms of its electron donating/withdrawing character, along with the position of the substituent on the aromatic ring heavily influences the reaction rates. Increasing the number of ortho methoxyl groups dramatically increased the reaction rate, e.g. phenol < guaiacyl < syringyl model structures. The ortho methoxyl group(s) resonance stabilizes and delocalizes the forming phenoxyl radical intermediate. Similarly, the reaction rate of para-substituted guaiacyl and syringyl model compounds showed a dependence on the nature of the para-substituent; inductive or resonance conjugated electron withdrawing effects and inductive donating effects. The effect of POM oxidation on the chemical structure of a Lodgepole pine MWL is investigated. ¹³C nuclear magnetic resonance (NMR) spectroscopic data revealed an approximate 28% decrease in β-O-4 inter-unit linkages after POM treatment, the decrease in β-O-4 inter-unit linkages being accompanied by an increase in carbonyl content. These results suggest that POM oxidation involves side-chain (such as α-OH/β-O-4) oxidation. ¹³C NMR spectroscopy along with gel permeation chromatography revealed an increase in the degree of condensation which supports the idea that radical coupling is a major reaction pathway in this process.Forestry, Faculty of

Mestrado em Engenharia Eletrónica e TelecomunicaçõesIn recent years, Internet has been assuming a fundamental role in everyday life. Traffic demands are increasing in such a way that the available technologies will presumably no longer satisfy the raised requirements. For the last years, operators have expressed a clear interest in the implementation and development of Passive Optical Network (PON) to provide several services and applications to a high flow rate per client. Comparing to other access technologies, PON is very attractive mainly due to reduction of maintenance and to the operational cost efficiency. As a consequence, PON systems were standardized and developed in the whole world, but the everincreasing bandwidth demand makes this type of network need to evolve. Therefore, the current standardized technologies Gigacapable PON and XG-PON need to be upgraded to Next-Generation PON2. In order to protect the initial investment and to reduce the operational costs, operators should keep the current optical distribution network, providing the technologies coexistence in the same fiber. The principle of NG-PON2 is to improve previous technologies, in terms of capacity, ODN compatibility, bandwidth and cost-efficiency. In April 2012, Full Service Access Network (FSAN) selected the time and wavelength multiplexing PON (TWDM-PON) technology as the solution of choice for NG-PON2. Almost one year later, ITU-T G.989.1 came out, providing some wavelength plans proposals. The ability to operate on existing fiber ODN, coexisting with legacy PON is the most important requirement. The current dissertation is based on the study of TWDM-PON upstream transmission. Both GPON and XG-PON work in burst mode for upstream direction, therefore in the current study also that type of data transmission is considered for upstream TWDM-PON. Once using this transmission mode, some parameters have to be taken into consideration, as the packets size and their separation length in order to understand which frame fits the best, considering the system performance. In the actual study, it was supposed to visualize transients in each packet, however it was experimentally proved that once the lifetime of the carriers is less than the burst time, it was not possible to identify any of them. It was also verified that increasing the guard time will decrease the performance of the system.
A Internet tem vindo a assumir um papel fundamental no quotidiano de cada utilizador. A largura de banda exigida é cada vez mais alta, desta forma, as tecnologias actualmente disponíveis acabarão por deixar de satisfazer os requisitos emergentes. Nos últimos anos, as operadoras têm manifestado um interesse evidente no desenvolvimento de Redes Ópticas Passivas (PON), com o intuito de fornecer vários serviços e aplicações a uma taxa de fluxo elevada por cliente. Comparando com outras tecnologias de acesso, as redes PON são muito actrativas devido à sua baixa manutenção e aos custos/eficiência de operação. Como consequência, os sistemas PON foram padronizados e desenvolvidos em todo o mundo. No entanto, este tipo de tecnologia necessita de progredir ao longo do tempo, mantendo a satisfação dos requisitos de tráfego que lhe serão impostos. Assim, as tecnologias actualmente implementadas: GPON e XG-PON, necessitam de sofrer um upgrade para NG-PON2 (Next- Generation PON 2). De modo a proteger o investimento inicial, reduzindo os custos de operação, as operadoras devem manter e reutilizer a ODN já implementada, possibilitando a coexistência das tecnologias na mesma fibra. NG-PON2 é uma melhoria da capacidade, da compatibilidade na ODN, largura de banda e custo-eficiência das tecnologias anteriores. Em Abril de 2012, a FSAN selecionou a tecnologia TWDM-PON (Time and Wavelength Division Multiplexing PON) como solução do projecto NG-PON2. Um ano após a sua seleção, a norma ITU-T G.989.1 foi publicada, propondo alguns planos de comprimentos de onda. A coexistência de TWDM-PON com as PON anteriores na mesma ODN é o requisite mais importante. A presente dissertação baseia-se no estudo de transmissão upstream de TWDM-PON. Ambos GPON e XG-PON operam em modo burst para a direção upstream. Uma vez utilizao este modo de transmissão, é necessário considerer determinados parâmetros como o tempo de separação interburst – guard time, tal como o comprimento de cada pacote, com o intuito de compreender o impacto da variação destes mesmos campos no desempenho do sistema. No presente estudo, era susposto visualizar transientes em cada pacote de transmissão, no entanto foi comprovado experimentalmente, que uma vez que o tempo de vida dos portadores do EDFA selecionado é menor que o intervalo de cada burst, não se identificaram transientes. Verificou-se também que, o aumento da separação interburst degrada o desempenho do sistema.

Full textAbstract:
This work deals with the closed-loop control of disturbances which develop linearly in laminar and incompressible flows. The control of both oscillator and amplifier flows is assessed. We consider a LQG control strategy in which the control law is computed using a reduced-order model of the flow. This reduced-order model is obtained by a Petrov-Galerkin projection. The first part is devoted to the stabilization of an open cavity flow which behaves as an oscillator. It is shown that the unstable subspace of the flow (the unstable global modes) and the input-output behaviour between the actuator and the sensor of the stable subspace must be captured by the reduced-order model to stabilize the system. Global modes, POD modes and BPOD modes are successively evaluated as projection bases to construct a reduced-order model of the stable part of the flow. It appears that global modes are not able to reproduce the input-output behaviour of the stable part of the flow and subsequently may only stabilize the flow if the instability is very weak (close to the criticality). On the contrary, reduced-order models based on POD modes and BPOD modes efficiently extract the input-output dynamic of the stable subspace and are successful to stabilize the flow. The second part of this work is dedicated to the reduction of the disturbances' amplification on a backward facing step. The influence of the sensor's location and of the cost functional on the performance of the compensator is studied. It is shown that the truncation of the reduced-order model may lead to an unstable closed-loop system. Finally, the possibility to control a non-linear simulation using a linear compensator is evaluatedCe travail est consacré au contrôle en boucle fermée des perturbations se développant linéairement dans des écoulements laminaires et incompressibles de types oscillateurs et amplificateurs de bruit. La loi de contrôle, calculée selon la théorie du contrôle LQG, est basée sur un modèle d'ordre réduit de l'écoulement obtenu par projection de Petrov-Galerkin. La stabilisation d'un écoulement de cavité de type oscillateur est traitée dans une première partie. Il est montré que la totalité de la partie instable de l'écoulement (les modes globaux instables) ainsi que la relation entrée-sortie (action de l'actionneur sur le capteur) de la partie stable doivent être captées par le modèle réduit afin de stabiliser le système. Les modes globaux, modes POD et modes BPOD sont successivement évalués comme bases de projection pour modéliser la partie stable. Les modes globaux ne parviennent pas à reproduire le comportement entrée-sortie de la partie stable et par conséquent ne peuvent stabiliser l'écoulement que lorsque l'instabilité du système est initialement faible (nombre de Reynolds proche de la criticité). En revanche, les modes POD et plus particulièrement BPOD sont capable d'extraire la dynamique entrée-sortie stable et permettent de stabiliser efficacement l'écoulement. La seconde partie de ce travail est consacrée à la réduction de l'amplification des perturbations sur une marche descendante. L'influence de la localisation du capteur et de la fonctionnelle de coût sur la performance du compensateur est étudiée. Il est montré que la troncature du modèle réduit peut rendre le système bouclé instable. Finalement, la possibilité de contrôler une simulation non-linéaire avec un modèle linéaire est évaluée

This thesis is a numerical study of the coupled Burgers equation. The coupled Burgers equa- tion is motivated by the Boussinesq equations that are often used to model the thermal-fluid dynamics of air in buildings. We apply Finite Element Methods to the coupled Burgers equation and conduct several numerical experiments. Based on these results, the Group Finite Element method (GFE) appears to be more stable than the standard Finite Element Method. The design and implementation of controllers heavily relies on rapid solutions to complex models such as the Boussinesq equations. Thus, we further examine the feasibil- ity and efficiency of the Proper Orthogonal Decomposition (POD) for the coupled Burgers equation. Using POD, we reduce the system to a â minimalâ number of ODEâ s and conduct numerous numerical studies comparing the POD and GFE method. Further numerical ex- periments consider an application where the dynamics are projected on a POD basis and then the governing parameters of the system are varied.Master of Science

The model adequately reproduces all significant modes observed on the spectra of measured velocity and temperature and helps to identify the different modes. The simulations show the importance of rotational modes for the internal wave field of the stratified reservoirs. Under the studied wind regime, the Rossby radius for the Sau Reservoir is of the order of 100 m, that is, several times smaller than the amplitude of the lacustrine zone of the reservoir, and the Rossby number is of order of 0.1, which corroborates the importance of the Coriolis effect.

In recent years, pop music concerts have become the main driving force for the development of the industry and continued to innovate. As it further leads the booming development of domestic ticketing market in Taiwan, the concert ticketing has begun to attract attention from the market and the industry. Taking the domestic ticketing system operators as the research subject, this study described the development of the ticketing industry of Taiwan’s pop music concerts along with the development of the market and industry, and further explored the business model of the domestic ticketing industry, analyzing its current situation, difficulties, and future prospects. Given the insufficient analysis, research and literature materials regarding the ticketing industry of Taiwan’s pop music concerts in the past, this study not only collected relevant literature and source data by using the secondary data analysis method, but also conducted in-depth interviews with six experts in the ticketing industry. The data from both sources were then summarized and analyzed. From the research results, this study found that the development of the domestic ticketing industry can be divided into six phases: the manual ticketing period, the launch of computer ticketing, the emergence of online ticketing, the joining of convenience store operators, mobile devices and cloud-based ticketing system, and the rise of secondary ticket market. With the development of the concert market and science and technology, the domestic ticketing industry has gradually moved towards a demassified market and provided exclusive services. Today, with flexible elements, the ticketing system’s structure can be adjusted according to the characteristics of the performers or the attributes of the performances. Through the B2B2C transaction model, the concert ticketing industry creates value for companies and customers. Therefore, in order to meet the needs of the organizers, the ticketing industry must provide fans with the ticketing service, which forms the concept of a two-way service. The current chaotic scalper situation in the ticketing market is originated from the structural problems of past government policies, which also causes the potential risk of loss for concert promoters due to the policy loophole. In response to this, the government published the amendment to the “Performing Arts Ticket Standard Contract” in 2018. It will be worth observing that whether it could have a positive impact on the industry and the market, as well as whether domestic companies could develop official secondary ticket websites in the future. Since the development, the role of ticketing has shifted from passive to active, entering the core ecosystem from the bottom of the industry chain.

In the popular music industry, the physical discs sales often used to measure popularity of an artist. However, with the advances in technology, internet prosperity and digitization, consumers download the music instead of buying physical albums. The core competency of popular music industry transformed from selling physical discs to comprehensive artist management which means the major revenue comes from artist management, live performance or copyright etc. The IFPI (International Federation of the Phonographic Industry) indicated hat the new trend in the global music industry is the Experience Economy. Consumers expect to get real or surreal sensual experience through participation in a particular scene. It will be the major elements that we want to figure out about how to present the live concert, how to create the surprise, impressive scene, how to expand clients, and capture repeat customers. The study is to analyze the popular music concert business model of N company by using the Business Model Canvas and provide a useful and workable business model for this industry as a reference. The study indicates that the key success factors of N company including ‘Innovative value proposition’, ‘Unique key resources’ and ‘Fans feel more connected to their favorite artist’. N company invests in the technology to improve the platforms and provides the best access and information for fans to buy tickets and see the live events about which they are passionate. In addition, N company encourages consumers to provide feedback and suggestions as it is a way to improve their services, and to give the company direction in what consumers want from an entertainment provider. Through long-term management and integration, the N company owns unique key resources, and these also attract more external resources to join the network, forming a virtuous circle. In order to keep the competition strength, N company leverages the leadership position in live entertainment and the relationships with fans, sponsor, venues and artists to sell more tickets and grow the revenue. Added to this, N company builds the industry’s first artist-to-fan vertically integrated concert platform to simplify the cost structure and increase the differentiation.

Recently, pop musical industry was turned physical musical market into digital musical industry. The total musical industry was declined, but the pop musical concerts have become the newest businesscanvas in pop musical industry. Besides, Taiwan consideres as the early development of Chinese pop music. The student population was growing with Chinese pop music, and concerts creating irreplaceable experiences to attract customers are graduating rise.The student population is graduating financial independent and high degree of acceptance for new things. Therefore, more and more customers of student love watching pop musical concerts. They treat watching concerts as an entertainment and also support their favorite singer to leave a good memory. In this research, we ponder this angle as start, and we study at student population in pop musical concert. We base on elaboration likelihood model. The customer will via central path or peripheral path to influence the purchase intention of concerts. In other words, central path means that customers areinfluenced by argument quality to enhance their purchase intention. However, peripheral path are influenced by reference groups which including informational, utilitarian and value-expressive influence to enhance their purchase intention. This research also discuss about the interfere effect of involvement, and reinforcing the purchase intention. Sample of 316 collected through questionnaire survey, and hypotheses are tested by regression analysis. The result showed that argument quality and reference groups are important in the process of forming the purchase intention. Involvement are cause different impacts in the process. Therefore, based on the result, this suggested to those who want to promote the pop musical concert, could take more consideration theinfluence of involvement may cause, as consumer areinfluenced by argument quality or reference groups towards the campaign so as to raise people’s awareness and intention to purchasepop musical concert, and providing an enduring way which may not only raise intention to the current situation but giving an new consumption pattern that consumers may choose.

In recent years, East Asia has been, overwhelmingly growing a new culture, that is Korean popular culture, or Korean wave. After the “Gangnam style” performed by Psy won a phenomenal success around the world, Korean pop music (a.k.a. K-pop music) has begun to attract a huge numbers of tourists to Seoul visiting the Gangnam district. Based on balance theory, this study seeks to investigate consumer’s impression on K-pop artists and destination image of Korean tourist attractions. Moreover, cultural proximity is incorporated into it. According to the literature of Hofstede’s cultural dimension and spokesperson theory, consumers are divided into Asian group and non-Asian group, and K-pop artists, individuals and groups, and then the hypotheses are proposed. Survey research is adopted, and convenience samples are collected from the Internet and the field. The result implies that there is a positive association between consumers, K-pop artist, and destination image. Furthermore, female consumers show stronger attitude towards K-pop artist and destination image than male ones. Finally, it is suggested that the association between celebrity and third party be strengthened to enhance consumers’ impression, and gender should be taken into consideration, as well.

Since 1970 until 1980, Taiwan folk music became popular, during that moment Jia Chang Liu’s creative team was the top record company. He trained a number of Chinese pop star, for example, Teresa Deng, Fei Fei Feng, Yu Ching Fei. Those pop star caused a lot of attention among the Chinese in Southeast Asia, especially Singapore and Malaysia Chinese been influenced the most, almost every local family know who they were. In the 1990s, after the mainland reform and opening, the emergence of a large number of Singapore and Malaysia pop idols flocked to Taiwan and the mainland market. Taiwan has always been a central base for Chinese pop music, coupled with Taiwan's sophisticated pop music production environment to attract a new batch of the singer to develop their music career. Malaysia and Singapore music producer believe that when to you get popular in Taiwan, is easy for you to enter China market. Lots of singer from Malaysia and Singapore has become mainstream pop music inheritors, some of the mainstream artists was slowly being forgotten, and some of them were failed to become mainstream. Why? Is it the difference business model will lead to a singer’s rise or fall? In this study, the singer will name it as a brand (human brand), through analysis the business model elements. To investigate the effects of this brand singer, divided according to geographical scale international type, national singer brand, and according to different types of brands collect eight singers case data used for analysis, by using the business model element, such as "Value proposition", "design of products and services", "resource deployment", "core strategy", "value networks", "revenue mechanism" total of six elements analysis, the development of the following results: 1."value proposition", "design of products and services", "core strategy", "resource deployment", "value networks", "revenue mechanism", the international brand significantly more than the national brand demand. 2.the international singer each business elements mean, of considerable importance. 3.the national singer average each business element, the remaining operating element of considerable importance, accept "revenue mechanism".
