Abstract:

This thesis deals with the segmentation of lung parenchyma and extraction of airways tree from three dimensional CT scans. The external mask of the lungs is created and subsequently used to ease the process of airway segmentation. In this work, some published methods for airways segmentation are described with focus on one, which is described more in detail and also implemented in MATLAB. The proposed approach is based on morphological grayscale reconstruction. Method is tested on the real patient CT scans and finally, the results are discussed.

Abstract:

Human health is significantly influenced by inhaled aerosols. Insight to the aerosol transport and deposition mechanisms is a prerequisite for both, toxicological protection against harmful particles and efficient application of inhaled therapeutic aerosols. The purpose of this doctoral thesis was to gain new knowledge of this topic on the basis of in vitro measurements. Phase-Doppler Anemometry was chosen for aerosol transport measurement, for it allows simultaneous measurement of particle size and velocity. Results were processed by means of statistical methods and frequency analysis. Deposition of spherical aerosol particles was measured by Positron Emission Tomography, while deposition of fibrous aerosol was measured by Phase-Contrast Microscopy combined with automated image analysis. All experiments were performed on physical models created on the basis of the real lung geometry. New knowledge of flow characteristics, transition from laminar to turbulent flow, effect of breathing pattern or particle size on aerosol transport and deposition in human lungs are outcomes of this work. Significant effect of the oral cavity was ascertained due to comparison of aerosol deposition in realistic and semi-realistic model with cylindrical smooth walls. Acquired data not merely extended our knowledge of aerosol behavior in lungs but it can also be used for validation of numerical simulations.

Abstract:

Several experiments were designed for utilization of fluorescence spectroscopy as a method of aerosol particle detection in a model of lungs. One of the experiments was to arranged use luminescent properties of DEHS (bis(2-ethylhexyl)decandioate) for calculating aerosol deposition. The outcome of this experiment was confirmation of clusters existence, which causes luminescence of DEHS. But the luminescence is not enough dependent on concentration and as such is not suitable for calculation of aerosol deposition. As the next experiment DEHS-fluorescein particles were generated by condensation monodisperse aerosol generator (CMAG), where water was used instead of isopropyl alcohol as a solvent. By this alteration the negative influence of DEHS was eliminated, which caused results refinements of aerosol deposition. Generation of fluorescein sodium salt particles by small-scale powder disperser (SSPD) was designed as a last experiment. The lower deposition efficiency measured by this method was caused by particles polydispersion. Photo records were used for documentation of Hot-spots. Outcomes of this study are new knowledge of fluorescence spectroscopy utilization for study of aerosol deposition and possibilities of fluorescent aerosol particles generation. Acquired data can serve for knowledge extension of possible detection methods for aerosol particles in the model of lung and can serve for validation of numerical simulations.

Desde sua aparição nos meios de comunicação de massa, a vinheta sofreu diversas alterações de ordem estética, temática e estrutural. Atualmente, ela tem duas funções na grade de programação das emissoras: a primeira, de pontuação, organizando o conteúdo televisivo, marcando a entrada e a saída do intervalo comercial; e a segunda, ligada à autopromoção das emissoras de televisão, buscando conquistar e fidelizar o telespectador. As atuais vinhetas do plim-plim, da Rede Globo, são bastante significativas para o estudo não apenas da evolução das vinhetas, mas também do mercado televisivo brasileiro, que está cada vez mais competitivo. Este cenário força as emissoras de TV a criar elos cada vez mais estreitos e emocionais com o telespectador. Ao mesmo tempo, as instituições midiáticas têm ocupado um lugar cada vez mais central na formação da identidade cultural na contemporaneidade. A televisão, em especial, mostra-se como um meio de comunicação bastante influente na produção das subjetividades, pois fornece uma série de conteúdos e representações que se ligam à formação da identidade nacional. No Brasil, a televisão é um meio que ocupa lugar de destaque e a Rede Globo é a maior representante desta situação do veículo no país. Através da análise das vinhetas do plim-plim, investigamos a estratégia discursiva que a Rede Globo, que percebe e coopta símbolos e narrativas da cultura nacional e tradição regional brasileira, para montar sua imagem institucional. A pesquisa revela como a Rede Globo se coloca como elemento central na vida dos sujeitos, aparecendo como conectivo entre as falas dialógicas da esfera pública e privada, expressas nas narrativas das vinhetas. Para isso, nos utilizamos das contribuições de pensadores sociais contemporâneos, como Gilles Lipovetsky, Anthony Giddens e Zygmunt Bauman e ainda das contribuições de Homi Bhabha, Néstor Garcia Canclini, Chris Barker, Stuart Hall e Arjun Appadurai, que nos aproximarão mais da perspectiva dos Estudos Culturais. A análise gerou quatro categorias básicas das vinhetas do plim-plim, que são: Comemorativas/Globo 40 anos; Cultura Brasileira; Centralidade da televisão/Rede Globo; Narrativas não-hegemônicas. Estas categorias provaram que a Rede Globo se liga aos símbolos e caracteres da cultura nacional e da tradição regional para montar seu discurso institucional, além de criar uma imagem de centralidade, seja na esfera privada ou na interação dos sujeitos com a esfera pública. Ao mesmo tempo, abriu espaço para a ambivalência e ambigüidade em seu discurso hegemônico, na medida em que deu lugar a narrativas não-hegemônicas nas vinhetas do plim-plim

Abstract:

Effondrement et poussée sont les deux étais qui font le soutènement de la surface picturale dans l’art contemporain. De cette hypothèse, est né un parcours esthétique à la recherche de ce qui crée l’événement dans la surface : l’espacement de la surface mallarméenne, l’ouvert de Maldiney et le « vide actif » chez Cézanne ou Mondrian, le saut ou « jump » de Willem de Kooning, l’incise, la déchirure, ce par quoi le regard semble tomber dans la surface, semble s’abimer dans ses dessous et provoquer ce que Walter Benjamin nomme l’image dialectique, un état-limite où la sensation d’effondrement intérieur se double d’un plaisir esthétique fondé sur une pratique de chiffonnier : la récolte de détritus ou de déchets pour créer un montage de temps, une surface complexe. Cet état-limite de la peinture est développé par Didi-Huberman grâce au concept de pan dont la force antithétique réunit les pôles entre lesquels s’écartèle la peinture : ordre et chaos, autrefois et présent, lointain et proche, structure et texture, vide et plein… Le battement qui en résulte fait naître, fait pousser un regard autre, caractéristique de l’aura dont on se demande si elle n’est pas l’origine même de la peinture et non pas sa conséquence, ses effets. Ainsi, la question de l’aura génère-t-elle des questions plastiques telles que la trace, la marque, le trait, le blanc, le vide, le rien… mais aussi celles du pli, du dépli, du repli et de son équivalent le retrait. La métaphore anthropologique de la peau est le fil conducteur de cette thèse dont les occurrences se retrouvent également dans la figure de l’arbre, de l’écorce, feuilles et nervures. Le livre ou le cahier auxquels est dévolue une partie de la recherche prend sa source dans la matière même de l’arbre, le liber, pellicule entre l’écorce et le bois. Le geste même de l’inscription est interrogé et, avec lui, les lieux et les temps mêmes de sa déposition, surfaces picturales Pictorial surfaces: collapse & thrust is based on the assumption that the “surface entity”, following the expression coined by Christian Bonnefoi, is the unstable location of painting, whose construction can only be chronological. An aesthetic journey unfurls on the foundation of this allegation, the first step being the attempt to determine a typology of surfaces : surface spacing as in Mallarmé’s work, the “open” in Maldiney’s work, with “active emptiness” in Cezanne or Mondrian’s work -, and also, what opens the body of painting. The rift on the surface, the missing part has the value of Willem de Kooning’s leap or “jump”. The incision, the tear through which the eye seems to drop onto the surface takes the shape of a strip, grating or mesh. Collapse can put on the attire of disaster. What emerges at the precise spot where stars fell is the dialectical venue of images, a border-line where the sensation of inner disintegration comes with an aesthetic pleasure based on a practice giving preference to withdrawal and generating a complex surface. This border-line of painting is taken up by Didi-Huberman, with the concept of “face”, whose antithetical strength brings together poles between which painting is torn apart: order and chaos, past and present, distance and proximity, structure and texture, emptiness and completeness. The resulting pulsation gives birth to, creates a different vision, which characterises the aura which may be the very origin of painting, we may wonder, not its consequence or effects. So, the question of the aura reaffirms the idea that there is something unknown about the surface and gives rise to the question of sensation in painting and concomitantly that of memory in the creative process

Abstract:

Au cours du séchage, les milieux tels que les boues, vernis, peintures subissent différentes transformations physico-chimiques ainsi que d'importantes déformations sous l'effet des contraintes de rétraction. Un grand nombre de processus peuvent ainsi apparaître : formation de fractures, décollement revêtement/substrat, formation de plis, cloques,... Ces processus apparaissent à différentes échelles et présentent en particulier un grand intérêt pour les tableaux de Maîtres (rénovation, authentification, techniques des peintures). Deux systèmes modèles seront présentés afin d'étudier de telles instabilités. D'une part les suspensions aqueuses de particules colloïdales qui, au cours de l'évaporation du solvant, conduisent à la formation d'un gel fragile, siège de fortes contraintes mécaniques. D'autre part une goutte de solution d'un polymère vitreux à température ambiante qui, au cours du séchage, subit des déformations variées en fonction des conditions expérimentales.

Abstract:

Nous sommes partis d'une analogie inédite entre la configuration de certaines feuilles dans le bourgeon et les ribambelles de papier. Quand on plie du papier et qu'on le coupe avec des ciseaux, à chaque pli va correspondre une pointe ou un creux de la ribambelle déployée. De nombreuses feuilles adoptent la même géométrie dans le bourgeon. Le bord de la feuille est replié sur un plan comme s'il avait été découpé avec des ciseaux. Pour cette raison purement géométrique, les lobes et creux de la feuille déployée correspondront exactement aux plis initiaux. Nous avons nommé ces feuilles « kirigami », ce qui veut dire plié et découpé en japonais. La première partie de cette thèse, purement géométrique, montre à quel point les géométries des feuilles sont contraintes par leur développement plié. Nous montrons aussi que la richesse des géométries que permet le kirigami se retrouve au sein des feuilles. La deuxième partie, plus biologique, propose à la fois un mécanisme pour le développement des plis et un candidat pour les mystérieux ciseaux. Nous concluons sur l'intérêt évolutif d'une telle organisation des feuilles dans le bourgeon We have noticed an original analogy between the leaf configuration in the bud and the paper dolls. If you fold a paper sheet and cut it with scissors, each fold will give either a sinus either a lobe when you unfold it. A lot of leaves follow this geometry in the bud. The leaf margin is folded on a plane as if it had been cut with scissor For this purely geometric reason, lobes and sinuses of the unfolded leaf exactly correspond to the initial folds. We have called these leaves "kirigami", which means fold and cut. The purely geometric first part of this thesis shows how much the leaves geometries are constrained by their folded development. We also show that these geometries are very diverse and create very different leaves shapes. The second more biologic part proposes a mecanism for the fold development and a candidate to play the scissor role. We conclude by giving an original insight on leaf shape evolution

Abstract:

PONTIFÍCIA UNIVERSIDADE CATÓLICA DO RIO DE JANEIRO O crescente interesse na utilização das redes de distribuição de energia elétrica como uma alternativa para o fornecimento de serviços de telecomunicações, tem motivado a pesquisa e o desenvolvimento de sistemas capazes de superar as características hostis deste ambiente como canal de comunicação. Com esta finalidade, este trabalho procura estimar o comportamento da rede PLC através da modelagem da função de transferência do canal, para a faixa de freqüência de 300 kHz a 30 MHz, por meio de um conjunto de parâmetros, os quais podem ser deduzidos da medição da resposta em freqüência. Dois modelos são apresentados para descrever a resposta em freqüência complexa de típicos canais power line, cobrindo todos os efeitos que os caracterizam, tais como o efeito de propagação por multipercursos causado pelas inúmeras reflexões nas junções da rede e o desvanecimento seletivo em freqüência. Os experimentos revelam que estes modelos apresentam todas as características principais da rede PLC podendo representar ferramentas úteis e efetivas na prática, oferecendo a possibilidade de realizar pesquisas para diferentes topologias de rede, a fim de estudar seu impacto no sistema de comunicação pela rede de energia elétrica. Além disso, propõem-se modelos de ajuste da função de transferência do canal a dados empíricos pelo método dos mínimos quadrados. The crescent interest on the utilization of the low voltage power distribution grid as an alternative to provide services of telecommunication has motivated the systems development able to surpass the hostile characteristics of this environment as a communication channel. Therefore, this work seek to estimate the behavior of PLC network (Power Line Communication) through the modelling of the channel transfer function, to the range of 300 kHz to 30 MHz, by means of a set of parameters, which can be derived from the measure of the frequency response. Two models are presented to describe the complex frequency response of power line channels, covering all effects that define them, for example, the multipaths propagation generated by uncountable reflections on the network connections and selective fading in the frequency. The results of experiments show that these models present the most important characteristics of PLC network, representing useful and effective tools in the practice, offering the possibility to do researches to different network topologies, in order to study the impact of these effects on the PLC system. Moreover, they`re proposed channel transfer function adjustment models through empiric data and the least square method.

Abstract:

Mestrado em Finanças Este Trabalho Final de Mestrado consiste numa avaliação e consequente recomendação da ação da BP PLC, empresa multinacional cotada na Bolsa de valores de Londres, que opera na Indústria de Petróleo e Gás. De modo a desenvolver esta análise e apurar o price target da BP PLC no final do ano de 2020, foram aplicadas três metodologias: o Método dos Fluxos de Caixa Descontados, o Modelo dos Dividendos Descontados e ainda a Avaliação por Múltiplos. A primeira abordagem vai ao encontro da realidade da empresa, tendo em consideração a solidez na sua estrutura de capital, o segundo, deriva da estabilidade no pagamento de dividendos que a BP PLC proporciona aos seus acionistas e, o último assenta numa avaliação baseada na análise de empresas comparáveis do setor. Das abordagens mencionadas, foi dado enfase ao Método dos Fluxos de Caixa Descontados, resultando numa recomendação para manter com um price target de GBP 5.985 / ação, implicando um potencial de valorização na casa dos 14% sobre a cotação de GBP 5.002 / ação a 30 de agosto de 2019. No entanto, é fundamental alertar para o alto risco inerente a esta recomendação, com especial foco na volatilidade que os preços das commodities têm registado, o que tem provocado uma constante incerteza junto dos investidores, como também no possível efeito Brexit. As informações e referências utilizadas no desenvolvimento do relatório cingem-se a informação pública disponibilizada à data de 31 de agosto de 2019. Desta forma, qualquer informação subsequente não foi tida em consideração. This Master's Final Work consists of a valuation and consequent recommendation of BP PLC stock, a multinational company listed in the London Stock Exchange, operating in the Oil & Gas Industry. In order to develop this analysis and determine BP PLC price target at the end of 2020, three different methods were applied: the Discounted Cash Flow method; the Discounted Dividend model and the Multiple Valuation model. The first approach meets the reality of the company, taking into account the soundness of its capital structure, the second derives from the stability in dividend payments that BP PLC provides to its shareholders and, the latter proposes based in the analysis of comparable companies in the sector. Of the above approaches mentioned, the main focus was on the Discounted Cash Flow method, resulting in a hold recommendation with a price target of GBP 5.985 per share, implying a potential appreciation of around 14% against August 30th, 2019 closing price of GBP 5.002 per share. However, it is important to emphasize the high risk inherent in this recommendation, particularly on the volatility that commodity prices have experienced, which has caused constant uncertainty among investors, as well as the possible Brexit effect. The information and references used in the development of the report are limited to information made available to the public as of August 31st, 2019. Therefore, any subsequent information or events were not taken into account. info:eu-repo/semantics/publishedVersion

Mestrado em Finanças No decorrer deste Equity Research o preço das ações da Mondi plc sofreu grandes flutuações devido à pandemia COVID-19. Apesar disto, a Mondi plc é uma empresa matura e verticalmente integrada, dois factores importantes sobre a força da Mondi que a ajudam a sobreviver as incertezas trazidas pela pandemia. Esta avaliação contem informação até dia 6 de novembro de 2020, onde o preço de fecho foi 17,64€ por ação. De acordo com a avaliação feita foi definido um nível de risco médio. Foram utilizados quatro métodos de avaliação diferentes: método Discounted Cash Flow (DCF), método Adjusted Present Value (APV), Método de avaliação relativa através de múltiplos e o Dividend Discount Model. Através destes métodos foi obtido um preço-alvo de 20,0€ por ação para 2021YE. A Covid-19 teve um grande impacto na avaliação da Mondi plc. Os riscos derivados da pandemia Covid-19 são difíceis de interpretar, uma vez que não se sabe durante quanto tempo a pandemia vai durar. A minha recomendação de investimento para a Mondi plc é HOLD, com um upside potencial de 13,4%. During this equity research the stock price of Mondi plc was fluctuating heavily due to COVID-19. However, Mondi plc is a mature and vertical integrated company, two important aspects why Mondi plc is strong to survive the uncertainties of COVID-19. This pandemic will have a structural change on the value chain of Mondi plc. This valuation has as a valuation date as of Friday the 6th of November 2020, on which the stock price was on €17,64/sh. This valuation is assessed as medium risk. For the valuation four different valuation methods were used: The discounted Cash Flow Method (DCF), Adjusted Present Value Method (APV), Relative valuation Method (Multiples) and the Dividend Discount Model. These different valuations led to a target price of €20,0/sh for 2021YE. COVID-19 had a heavy impact on the valuation of Mondi plc. The risks regarding COVID-19 are hard to interpret since it is unknown how long this pandemic will last. To HOLD is my recommendation for Mondi plc with an upside potential of 13,4%. info:eu-repo/semantics/publishedVersion

Abstract:

Up to now there are not detailed studies about the structures and the kinematic related to the Plio-Pleistocene tectonics in southern Sardinia, although tectonic activity during the latest million years is long since known in the Island. Then, the general aim of this research is to improve the understanding of the recent geological evolution of the southern Sardinian block, trying to calculate the extension affecting the crust, to reconstruct the paleostress fields and to define a model of the tectonic evolution of the southern Sardinia during this period, considering the new data obtained from this research and the data available from literature on the geodynamic evolution of the western Mediterranean, in particular about the opening of the Tyrrhenian Sea. To achieve this purposes, the research focuses on the study of the most important structure related to the Plio-Pleistocene tectonics: the "so-called" Campidano graben. This structure has been studied mainly interpreting the seismic lines acquired in the Campidano plain by SAIS in the early sixties and by the joint venture AGIP-Progemisa S.p.A. in the early nineties that have been made available for this research by the Regione Autonoma della Sardegna and Progemisa S.p.A. The continuation of the Campidano in the Cagliari Gulf has been studied interpreting the ministerial seismic lines aquired by AGIP in the seventies in the offshore of Cagliari. The main results achieved from the research are: - the 3D model of the Middle Pliocene erosional surface at the base of the Samassi formation detected in the subsurface of the Campidano plain; - the extension values and the deformation rates affecting the Campidano area during Plio-Quaternary times; - the reconstruction of the paleostress field active during Pliocene time in the Campidano graben; - a comparison between the structural setting of the Campidano and the structural setting of the southeastern Sardinian margin; - the integration of the data achieved during this research with the data available from literature on the geodynamic evolution of the western Mediterranean, in particular about the opening of the Tyrrhenian Sea. The 3D model of the Middle Pliocene erosional surface has been built using the two-way time structural maps of this surface carried out in both the northern and southern Campidano. This surface shows a gently rolling landscape, typical of the erosion and planation surface developed in continental environments, both in the subsurface of the southern and northern Campidano plain. In the Campidano of Oristano, the maximum depth of the bottom of the Samassi formation is approximately -1100 m, while in the southern it is roughly -900 m (mean velocity assigned 2 km/s). The two-way time structural maps show that both the northern and the southern Campidano graben are bounded in the western edges by master faults dipping to the east, but differences arise in the trends of the faults: mostly N-S in the northern Campidano and NW-SE in the southern Campidano. N-S normal faults affected the whole Samassi formation and the within-plate basalts that post-date it, so we may admit that an important extension occurred after its deposition, that is in Pleistocene time. The structures from seismic interpretation, that characterized the Plio-Quaternary evolution of the so-called Campidano graben have been validated during the drafting of the two-way time maps and with the structural and stratigraphic data available on surface. This allowed to construct a validated 3D model from which achieved the most possible reliable values of extension and paleostress. To quantify the Plio-Quaternary deformation in southern Sardinia the 3D model of the Middle-Pliocene erosional surface (roughly 3.5 Ma in age) has been considered. The extension has been calculated restoring the cross-sections achieved from the 3D model. In the southern Campidano, extension values range from 205 m to 596 m and the percentage of extension from 1.65% to 5.72%. In the northern Campidano extension values range from 171 m to 465 m and percentage of extension from 0.84% to 2.50%. Although the Plio-Pleistocene time-markers (3.5 Ma the erosional surface at the base of the Samassi formation and 2.5 Ma the surface sealed by the basalt lava flows in northern Campidano and a reflector calibrated with the Campidano1 well in the southern Campidano) are not very well constrained, they allow to estimate the vertical slip rate (0,6 mm/yr) and the extension rate (0,3 mm/yr in the northern Campidano and 0,4 mm/yr in the southern Campidano). Considering the erosional surface sealed by the basalt-lava flows of the "giare" to the east of Campidano that occurs up to 550 m above the sea level and the age of 3.0 Ma of the basalts that seal it, an uplift rate of 0.18 mm/yr can be calculated if a marine origin for this surface is confirmed. Furthermore, the difference in elevation between the higher basalts that crop out in the central Sardinia (approximately 700 m in the Orroli basalt plateau) and those detected in the subsurface (-440 m in the northern Campidano) is related to tectonic activity that is at least Pleistocene in age. Therefore, during the whole Plio-Quaternary tectonics, considering the Middle Pliocene erosional surface at the base of the Samassi formation detected at -1100 m in the northern Campidano, vertical displacements on the order of 1800 m can be inferred. The paleostress field active during Pliocene time in the Campidano area has been reconstructed using the movement vector on the fault plane achieved from the restoration of the Middle Pliocene erosional surface in both the northern and southern Campidano using two different methods that showed almost the same results. In the northern Campidano, an extension oriented roughly E-W, with the principal stress axes: σ1=263/77; σ2=356/1; σ3=86/13; has be inferred. In the southern Campidano, the extension is oriented roughly ENE-WSW, with the principal stress axes: σ1=105/85; σ2=332/3; σ3=242/3. The evolution during Pliocene in the southern Sardinia seems to be strictly related with the evolution of the sector of the southern Tyrrhenian basin located roughly south of the 40° parallel. This can be infer from the similarities in ages and stuctures in the eastern Sardinian margin and Campidano area. It seems that the extensional tectonics started in the Upper Miocene in the Sardinian Basin and Cornaglia Terrace and migrated westward in Sardinia and eastward in the Vavilov Basin. Concerning the Pliocene tectonics affecting Sardinia, therefore, it seems to be directly related to the beginning of the extension in the Tyrrhenian Basin, due to the eastward roll back of the subducting Adriatic plate. It seems, instead, that the Pleistocene tectonics recognized in Sardinia can not be related directly with the evolution in the Tyrrhenian Basin, because, although extensional tectonics continued in the Marsili Basin until now, no active tectonics occurs in the Sardinian Basin and Cornaglia Terrace. Thus, the recent uplift affecting the southern Sardinia is most likely related to the lithospheric structure inherited from the pre-Pliocene geodynamic evolution of the western Mediterranean, during which the lowering of the density in the mantle lithosphere could be caused an uplift up to 1620 m, if a normal thick mantle lithosphere (90 km) is considering as start point, or up to 720 m, considering the present day thinned mantle lithosphere (40 km), or by the thinning of the mantle lithosphere connected with process of intensive convective heating (thermal thinning).

Nesse sentido, o modelo de canal com retransmissor único em dois estágios é investigado para sistemas de comunicação em banda larga através da rede de energia elétrica. Este modelo de canal cooperativo é formado pela concatenação de dois canais com retransmissor único, cobrindo enlaces de comunicação de dados com até dois saltos. Além disso, um modelo de canal híbrido com retransmissor único, utilizando rede elétrica e ar, é analisado para sistemas de comunicação de dados em banda larga em que enlaces de até um salto são considerados. Expressões de taxas de dados alcançáveis ergódicas são derivadas para os modelos de canais cooperativos híbridos e não híbridos, a fim de compará-los. Devido às características de canais e ruído das redes de energia elétrica, os resultados numéricos são baseados em um conjunto de dados constituído por estimativas de canais e medições de ruído cobrindo a faixa de frequência de 1, 7 a 100 MHz e diferentes posições do nó retransmissor. Para os canais sem fio, o modelo HIPERLAN/2 com a mesma largura de banda é utilizado, considerando uma freqüência central de 5 GHz, enquanto o ruído aditivo é considerado branco gaussiano. Com relação aos sistemas de comunicação através da rede energia elétrica, mostra-se que o modelo de canal com retransmissor único em dois estágios é a melhor opção quando o enlace da fonte ao destino encontra-se severamente degradado (por exemplo, alta atenuação de sinal devido à longa distância entre nós fonte e destino e/ou presença de ruído de alta potência). Quando a degradação do canal não é acentuada, o modelo de canal de dois saltos é mais apropriado. Acerca dos sistemas híbridos, constata-se que, quando o retransmissor está no meio do caminho entre fonte e destino, o modelo de canal híbrido com retransmissor único apresenta o melhor desempenho em termos de taxa de dados alcançável ergódica, enquanto o modelo de canal híbrido de um salto oferece os melhores resultados para outros casos. This dissertation aims to discuss hybrid and non-hybrid cooperative communications applied to in-home broadband data communication systems. In this sense, the two-stage single-relay channel model is investigated for in-home broadband power line communication systems. This cooperative channel model consists of the concatenation of two single-relay channels, covering data communication links with up to two hops. Moreover, a hybrid power line/wireless single-relay channel model is analyzed for broadband data communication systems, considering one-hop links. Ergodic achievable data rate expressions are derived for both hybrid and non-hybrid cooperative channel models in order to compare them. Due to channel and noise characteristics of electric power grids, numerical results are based on a data set constituted by power line channel estimates and additive noise measurements covering the frequency band from 1.7 up to 100 MHz and different relay positions. For wireless channels, the HIPERLAN/2 model with the same bandwidth is used, but at a central frequency of 5 GHz, while the additive noise is considered to be Gaussian white. Regarding only power line communication systems, it is shown that the two-stage single-relay channel model is the best option when the source-to-destination link is severely degraded (e.g., high signal attenuation due to the long distance between source and destination nodes and/or high-power noise presence). When the channel degradation is not severe, the two-hop channel model is more appropriate. Concerning hybrid systems, it is observed that, when the relay is halfway between source and destination nodes, the hybrid single-relay channel model presents the best performance in terms of ergodic achievable data rate, while the hybrid one-hop channel model yields the best results for other cases.

Abstract:

PLC kan idag vara det mest använda styrsystemet till industriella applikationer. Verifikation av programmerad PLC-logik är av stort värde och kan göras på olika sätt. ÅF Karlstad vill idag börja se över möjligheter till implementering av Virtual Commissioning som ett alternativ till minskning av ledtider. I det stora hela blev målet för detta projektarbete att i Xcelgo Experior bygga upp en 3D-miljö som liknar en saltvatten-process på Barilla i Filipstad, skriva PLC-logiken i Siemens TIA-portalen och testköra logiken i 3D-miljön. Och av detta kunna ge underlag till eventuella investeringar i denna teknik för ÅF Karlstad. Gränssnittet Xcelgo Experior visade sig var funktionellt och lättarbetat. Dock hann inte programutvecklarna få i stånd den uppdatering av modulkatologen som krävts för att tillräckligt kunna efterlikna Barillas process att det försvarbart skulle kunna verifiera PLC-logiken. Efter överläggande med min handledare på ÅF, Anders Emanuelsson, bestämdes att i stället verifiera logiken visuellt i Siemens HMI. Då detta projektarbete endast delvis kommer uppfylla de syften och mål som satts kommer istället en verifiering av PLC-logiken för processen att utgöras av Siemens HMI. Dock har användandet och testkörning av mindre skriven kod, anpassat för nuvarande version av Xcelgo, givit en bild av möjligheterna att effektivt validera PLC-logik då en version lämpad mer för den Värmländska industrin kommit.

Cette thèse porte sur l' ́etude expérimentale des déformations générées par la tension de surface de certains liquides sur des membranes flexibles. Dans une première partie, nous montrons expérimentalement qu'il est possible de contrôler l'enrobage spontané d'une membrane flexible autour d'une goutte d'eau 'a l'aide d'un champ ́electrique. Si la tension augmente au delà d'une valeur critique la membrane s'ouvre. Cette transition est réversible, mais inclus une forte hystérésis. Nous proposons des lois d' ́echelle pour les tensions critiques d'ouverture et fermeture basées sur l'interaction des ́energies de tension de surface, ́elastique et du champ ́electrique. Dans la deuxième partie nous ́etudions les rides générées par la différence de tension de surface entre l'intérieur et l'extérieur de une couronne flexible flottant à la surface de l'eau. Nous avons estimé des critères simplifiés pour le seuil de flambage de la couronne et la longueur d'onde des plis, et nous avons ́egalement d ́etermin ́e l' ́evolution de la longueur des plis au delà du seuil. Dans la dernière partie de la thèse, nous ́etudions la morphologie de cascades de plis qui apparaissent dans différents systèmes lorsqu'une longueur d'onde est imposée sur une frontière, et ́evolue à la suite d' ́evénements discrets successifs de coalescence de plis. Des expériences ma- croscopiques nous permettent de caractériser les propriétés de ces cascades. Nous avons distingué deux régimes différents selon l'importance de la tension axiale. Nous avons vérifié que nos lois d'échelle permettent de décrire aussi bien des rideaux en tissu de plusieurs mètres de haut que des feuilles de graphène d'épaisseur atomique.

Abstract:

Le premier but de cette thèse est de développer une méthode objective pour l'interprétation de profils sismiques et des structures qui sont susceptibles d'être des réservoirs pétroliers. Le deuxième but est l'amélioration de la prévision des fractures dans les roches laminées, qui déterminent la perméabilité. Les expériences et les résultats analytiques montrent l'initiation, l'évolution et l'arrêt d'un kink et d'un pli de propagation de rampe (PPR). Les expériences avec paraffine multicouches établissent la relation entre la distribution des fractures, la formation des charnières endommagées et l'évolution d'un pli de kink. Les résultats analytiques se fondent sur des règles géométriques combinées à l'approche externe de l'analyse limite. Les bandes de compaction, les failles et les plis sont en concurrence à l'initiation du kink. Le mode dominant dépend de l'inclinaison des couches et de la profondeur d'enfouissement de la structure. Les résultats sont présentés dans une carte de mécanismes dominant dans l'espace des enfouissements et l'inclinaison des couches. La même approche est utilisée pour étudier le PPR dont l' évolution se termine à cause de l'initiation d'une faille. Parmi tous les paramètres, c'est l'angle de friction dans les charnières qui contrôle cette transition. La deuxième partie de cette thèse présente les résultats expérimentaux, numériques et analytiques sur les fractures. Une couche composée de gypse compacté, est en extension par sa base et se fracture en mode I. La relation entre la distance entre les fractures et l'épaisseur d'une couche est linéaire, quand la structure est saturée en fractures. Cette saturation est liée à un décollement de la base de la couche. La méthode des éléments finis et la théorie de la plasticité permettent de valider ces résultats. L'approche analytique (analyse limite) a donné un critère simple pour prédire si un décollement ou une fracture va se former. Un nouveau critère pour la distance entre deux fractures est proposé. Dans la dernière partie de cette thèse, un nouveau dispositif expérimental est présenté afin d'étudier les fractures en flexion. L'épaisseur d'une couche n'influence pas la distance entre les fractures si il y a seulement une flexure. Cette influence est par contre grande si la couche est cintrée et en extension.

Abstract:

La structuration crustale de la chaîne actuelle des Pyrénées permet de définir quatre unités sismotectoniques. D'est en ouest de la chaîne, on distingue les Pyrénées Orientales, l'est et l'ouest des Pyrénées Centrales et les Pyrénées Occidentales. Ces unités montrent deux types de sismicité. Une, d'origine tectonique, accommode le déplacement relatif des plaques ibérique et européenne, l'autre est associée à une exhumation isostatique de la chaîne, induite par l'érosion de la Zone Axiale. Dans l'ouest des Pyrénées Centrales, une source sismique potentielle est identifiée dans le bassin d'Arudy et son rejeu Plio-Quaternaire est démontré. Dans la Zone Axiale d'autre structures potentiellement actives sont également identifiées et attribuées à la surrection isostatique de la Zone Axiale. Nous proposons un modèle de déformation actuel de l'ouest des Pyrénées Centrales où la compression transpressive dextre entre en compétition avec la surrection isostatique de la Zone Axiale The crustal architecture of the present Pyrenean range leads us to identify four seismotectonic units, from east to west (1) the Eastern Pyrenees (2) the Eastern and (3) Western Central Pyrenees and (4) the Western Pyrenees. These units are affected by two different seismicity patterns. The first mode of deformation is triggered by the relative oblique convergence between the Iberian and European plates whereas the second is a consequence of the isostatic exhumation of the mountain ranges, induced by erosion of the thick under-thrusted Iberian crust. In the Western Central Pyrenees, we show Plio-Pleistocene tectonic activity related to the occurrence of a potential seismogenic source in the Arudy area. We also observe potential active tectonic structures in the Axial Zone of the Pyrenees. These can be attributed to the accommodation of strain triggered by the exhumation of the Axial Zone of the Western Central Pyrenees. Finally, we propose an integrated strain model for the recent tectonic activity of the Western Central Pyrenees. In this area, the right-lateral transpression initiated by the oblique convergence between the Iberian and European plates is competing with vertical deformations triggered by the post tectonic surrection of the Axial Zone

Abstract:

Les episodes tectoniques ainsi reconstitues sont les suivants : deux episodes mineurs successifs de compression, diriges 75 et 15 (wsw-ene et nne-ssw) successivement, ont eu lieu tout d'abord. Ensuite, quatre episodes majeurs se sont produits avec respectivement des compressions : 155, 135 et 165 (nwn-ses, ns-sw, wnn-ese, nnw-sse). Les deux premiers episodes mineurs se sont vraisenblablement developpes anterieurement au pliocene inferieur (environ 4 ma). Les episodes majeurs de compression se sont developpes pendant le plio-quaternaire. Les principales caracteristiques de l'evolution des episodes tectoniques compressifs du plio-quaternaire a taiwan sont interpretables en termes d'evolution cinematique de l'orogene de taiwan. Premierement l'evolution des contraintes compressives est conforme a la migration de la collision du nord-est vers le sud-ouest, le long de la frontiere de plaques a l'est de taiwan. Deuxiemement, cette evolution est conforme a la propagation de la compression des zones internes ("hsuehshan-yushan range" et "backbone range") vers la zone externe ("foothills" et plaine cotiere), pendant la collision. Troisiemement, le changement anti-horaire de la direction de compression pendant le plio-quaternaire est un resultat du changement majeur de la direction de la convergence entre la plaque et la mer des philippines et la marge continentale chinoise. Ce changement cinematique est relativement simple, alors que la complexite apparente des distributions de contraintes resulte en grande partie de phenomenes tels que des perturbation des trajectoires de contrainte (liees a l'heterogeneite des structures) et des rotations locales de blocs dans la chaine de collision de taiwan

Abstract:

Orientador: João Andrade de Carvalho Resumo: Application technologies based on the detonation cycle has proven a significant impact on the overall efficiency. However, detonation engines are not currently available on the markets due to the lack of physical and chemical knowledge of the detonation phenomenon. The present study aims to provide new insights by studying the pressure and velocity, the density gradient of the detonation wave, and the OH distribution on the reaction zone of hydrogen-air detonation. Three strategies were proposed to obtain repeatable detonation events. The strategies vary on the geometry of the obstacle and the amount of spark plug to ignite the mixture. Pressure and velocity were recorded to determine if the transition from deflagration to detonation is successful. To image the density gradient of the shock wave, the optical technique called Schlieren was adapted to the detonation test bench. The OH radical distribution was studied by the optical diagnostic technique called planar laser-induced fluorescence. The pressure trace results showed high peaks in the regimen of Chapman-Jouguet state for detonation, unlike fast flames. The velocity results showed a considerable influence of the obstacle geometry to enhance the velocity of the wave, although the repeatable detonation events and the steadiness of the velocity were not boosted. The third strategy proved that adding more energy to a transient detonation wave, enhanced the stability and the consistent production of detonation events. The S...

Abstract:

Cette thèse porte sur l’étude expérimentale des déformations générées par la tension de surface de certains liquides sur des membranes flexibles. Dans une première partie, nous montrons expérimentalement qu’il est possible de contrôler l’enrobage spontané d’une membrane flexible autour d’une goutte d’eau à l’aide d’un champ électrique. Si la tension augmente au delà d’une valeur critique la membrane s’ouvre. Cette transition est réversible, mais inclus une forte hystérésis. Nous proposons des lois d’échelle pour les tensions critiques d’ouverture et fermeture basées sur l’interaction des énergies de tension de surface, élastique et du champ électrique. Dans la deuxième partie nous étudions les rides générées par la différence de tension de surface entre l’intérieur et l’extérieur de une couronne flexible flottant à la surface de l’eau. Nous avons estimé des critères simplifiés pour le seuil de flambage de la couronne et la longueur d’onde des plis et nous avons également déterminé l’évolution de la longueur des plis au delà du seuil. Dans la dernière partie de la thèse, nous étudions la morphologie de cascades de plis qui apparaissent dans différents systèmes lorsqu’une longueur d’onde est imposée sur une frontière, et évolue à la suite d’événement discrets successifs de coalescence de plis. Des expériences macroscopiques nous permettent de caractériser les propriétés de ces cascades. Nous avons distingué deux régimes différents selon l’importance de la tension axiale. Nous avons vérifié que nos lois d’échelle permettent de décrire aussi bien des rideaux en tissu de plusieurs mètres de haut que des feuilles de graphène d’épaisseur atomique

Abstract:

Syftet med examensarbetet är att digitalt tillämpa en stabilisering av pendlingar i den aktiva effekten hos en synkrongenerator för vattenkraft kopplad till ett distributionsnät.Implementeringen är tänkt att ske i en PLC som redan hanterar andra delar av magnetiseringen.Effektstabiliseringen görs genom att en motverkande styrsignal skickas till magnetiseringsutrustningen vilken i sin tur påverkar generatorns uteffekt. Denna motverkande styrsignal kan tas fram på olika sätt.Två modeller, av IEEE standardiserade, för effektstabilisering undersöks, PSS1A och PSS2B.En Simulink-modell över ett distributionsnät med generator byggs upp för att testa effektstabiliseringen.Diskretisering av den ena standarden utförs för att digital implementering ska kunna ske. Tester utförs även på denna modell för att kunna validera dess funktion i jämförelse med den kontinuerliga.Den tidsdiskreta modellen görs om till ett matematiskt uttryck tillämpbart i PLC:n.Jämförelse sker mellan simuleringarna och den tillämpade modellen genom mätningar. The purpose of the degree project is to make a digital realization of a stabilizer for oscillations in the active power from a hydropower synchronous generator, connected to a power network.The implementation is supposed to be done in a PLC which already handles part of the excitation system.The power stabilization is achieved by sending a counteracting reference signal to the excitation system which controls the generator’s output power. This counteracting signal can be achieved in several ways.Two existing models, standardized by IEEE, for power system stabilizing will be examined, PSS1A and PSS2B.A Simulink-model of a distribution net with a generator is constructed to test the stabilizers.To perform a digital implementation a discrete transformation of one continuous model is done. This discrete model is also tested to verify the function in comparison to the continuous one.The discrete model is reorganized in a form possible to implement in the PLC.Comparison between the simulated and the implemented model is made by measurement.

Abstract:

Automationscenter & Bråvalla Elteknik AB is a company that offers the market completed total solutions where the customer can operate and monitor their production from the terminal. In these total solutions they lack standard circuit which are developed by the company and which could manoeuvre/control/monitor controlled process objects. This report defines the work of developing the most common standard circuits.The report is initiated by a short theoretical part about PLC and the PLC system, with a connected terminal, which has been used. Thereafter, the turnout of the demands of specification is reported, after discussing with the supervisor in the course of the project. The report concludes with a disclosure of how the programming, the documentation and the testing have proceeded and a final discussion concerning the project and proposals on continuation.The result is a CD with the documentation of standard circuits and how they are implemented in a new project. One library file with the program code to all standard circuit. Program code and documentation for both demonstration and testing are also on the CD. This project represents a start of POS (Process Objektsstyrnings Standard) as the collection is called at Automationscenter. Automationscenter & Bråvalla Elteknik AB är ett företag som erbjuder marknaden färdiga totallösningar där kunden kan manövrera och övervaka sin produktion från operatörspaneler. I denna totallösning saknar företaget egna framtagna ”typkretsar” som manövrerar/kontrollerar/övervakar styrda processobjekt. En typkrets skall ha en del som implementeras i PLC och en del som implementeras i operatörspanelen.Denna rapport redogör för hur några av de vanligaste ”typkretsarna” tas fram.Rapporten inleds med en kort teoridel om PLC och det PLC‐system med tillhörande operatörspanel som använts. Därefter redogörs hur typkretsarnas kravspecifikation blev efter att ha diskuterat med handledaren under arbetets gång. Rapporten avslutas med en redovisning för hur programmeringen, dokumentationen och testningen gått till och en avslutande diskussion om arbetet och förslag på fortsättning.Resultatet blev en CD‐skiva med dokumentation om typkretsarna och hur de implementeras i ett nytt projekt: en biblioteksfil med programkoden till alla typkretsar. Programkod och dokumentation för både visning och testning finns också med på skivan. Ex‐jobbet utgör en början på POS Process Objektsstyrnings Standard som samlingen heter på Automationscenter & Bråvalla Elteknik AB.

Abstract:

The objective of the fi rst part of the thesis was to estimate risk and protective factors on lung cancer risk in females, especially to study the differences in the impact of diet and physical exercise on lung cancer risk in female nonsmokers vs. smokers, and reveal interactions, if any. In a hospital based case-control study, data collected by in-person interviews from 569 female lung cancer cases and 2120 controls were analyzed using unconditional logistic regression stratifying by appropriate factors. To investigate the role of tobacco and some other known or suspected factors responsible for the risk of developing adenocarcinoma of the lung, and to compare with other cell types (squamous-, small- and large-cell cancers) in Czech women, we conducted a case-control study, this is described as a second part of the thesis. Data collected by personal interviews from 145 cases of adenocarcinoma of the lung, 221 lung cancer cases of other cell types, and 1624 controls were analyzed using unconditional logistic regression.

Abstract:

Streptomycetes, primary soil saprophytic microorganisms are at the center of interest in many research groups, mainly because of their ability to produce a wide range of biologically active substances useful in medicine, biotechnology and agriculture. The marginal, and little explored areas are the interactions that streptomycetes create with humans. Recent metagenomic studies have shown that streptomycetes colonize the skin, the respiratory and possibly the urogenital tract of humans. In addition to apparent pathogens such as S. somaliensis and S. sudanensis, the clinical impact of these streptomycetes on human health is unknown. For this reason, a unique collection of non-pathogenic streptomycetes isolated from human clinical specimens was developed. The isolates were collected by the National Reference Laboratory for Pathogenic Actinomycetes in Trutnov, Czech Republic. On the basis of pilot studies, an isolate labeled TR42 was selected from the Trutnov collection, showing a very broad spectrum of biological activities. This strain was isolated from sputum from a patient with unknown respiratory diagnosis. The TR42 strain exhibits considerable biotechnological potential and after following a thorough study, it could be a source of new biologically active substances with pharmaceutically...

Topic: Functional imaging methods of lung cancer MUDr. Táňa Baráková, Klinika zobrazovacích metod FN Plzeň Introduction: The aim of my work was to assess the use of direct quantification of dual-energy CT (DE-CT) radiation in the diagnosis and monitoring of non-small cell lung cancer (NSCLC) therapy. The work consists of three studies that were performed on Department of imaging methods. The main objectives were to assess the contribution of iodine quantification from DE-CT examinations, to verify the setting and to incorporate the DE-CT examination of the chest into a routine investigation. Furthermore, to investigate the possible benefit of dual- phase DE-CT in evaluating both primary non-small cell lung cancer itself and lymph nodes in terms of iodine and size relationship in chemotherapy or targeted therapy, and finally to investigate the possible benefit of staging FDG-PET / CT to evaluate the effect of therapy on lymph nodes. Methodics: In all presented studies, the same DE-CT protocol was used in the early (arterial) and late (venous) stages. Using a dedicated software prototype, iodine content analysis was performed as the equivalent of blood circulation in lymph nodes and tumors. The main evaluated parameters were iodine content (mg), iodine uptake (mg / ml) and ratio of arterial enhancement...

Abstract:

Theme of her thesis dealing with lung cancer women I have chosen not only because it belongs to the Czech Republic countries with high incidence and mortality for lung cancer, but also personal interest in this issue. Lung cancer is by far the most common malignant us cancer in men. For women, the incidence of this tumor is about four times lower than in men, but worrying is the fact that the curve for women incidence has increased steadily. Although a direct link has been demonstrated a number of risk factors, especially smoking, another question arises about the influence of other substances, especially in women, where the representation ofdifferent histological different types of lung tumors. Therefore, there are hypotheses whether women have no share in the development of lung cancer, especially adenocarcinoma, hormonal influences. That was the impetus for writing this work, which I tried to find association between the occurrence ofadenocarcinoma in women and hormonal contraceptives, hormone replacement therapy and length of time between menarche and menopause.

Abstract:

The aim of the presented thesis is to introduce modern molecular methods that may contribute to deepening our knowledge of pulmonary carcinogenesis. Furthermore, we would like to point out the significance of immunohistochemistry in differential diagnostics of the most common primary pulmonary and pleural neoplasms. Lung carcinoma of all histological subtypes is a result of stepwise accumulation of genetic and epigenetic changes, including allelic losses (LOH), chromosomal instability and imbalance, oncogene and tumor suppressor gene mutations, epigenetic silencing by promotor hypermethylation or aberrant gene expression guidinig cell proliferation. In our study, certain genetic changes were detected in squamous cell carcinomas (SCC) of the lung, their precancerous lesions as well as in normal bronchial mucosa in a selected group of heavy smokers with limited ventilation. We investigated the relation between molecular changes of LOH type in chromosomal regions harbouring mismatch repair genes and cell cycle regulators and human telomerase reverse transcriptase (hTERT) mRNA expression. We also evaluated the relation between these molecular changes and histologic pattern in bronchial mucosa in this patient group. hTERT mRNA expression analysis in correlation with LOH in bronchial mucosa of heavy...

The wave breaking process such as water waves travel over a sloping bottom is investigated. To track free surface movements, the VOF (Volume of Fluid) coupled with PLIC (Piecewise Linear Interface Construction) method is employed. To ensure the accuracy of the numerical model, numerical results were compared with Ting and Kirby’s (1994) experiment data for the case of spilling breaker. Good agreement between numerical results and experimental data has been observed for shoaling and breaking cnoidal waves on a sloping bottom in terms of free surface profiles and mean velocities.

Abstract:

Background: Granzyme B (GrB) is a key proapoptotic secretory protease of CTLs and NK cells. Its specific proapoptotic effects in cancer cells can be blocked by increased expression of serpinB9. SerpinB9 gene expression can be transcriptionally upregulated by some interleukins and by the oestrogen activated oestrogen receptor-α (ERα) in cells which express ERα protein. The aims of my thesis were to evaluate the expression of SB9 and to examine its inhibitory activity against exogenous active GrB in non-small cell lung carcinoma (NSCLC) cell lines and tissues. To analyse the expression status of GrB mRNA in NSCLC cell lines and tissues. To investigate the role of estradiol-17β (E2), selected ILs and DNA methylation in regulation of SB9 expression in NSCLC cells. The apoptosome apparatus is a cell death signalling platform activates the initiator procaspase-9. Activation of the apoptosome apparatus is often impaired in various types of cancer but the molecular basis of its suppression is still unknown. APIP and UACA/nucling belong to the endogenous regulators of apoptosome apparatus. The aim of my thesis was to investigate whether DNA methylation is involved in the transcriptional regulation of expression of APIP and UACA genes in NSCLC cell lines.

Abstract:

Background Bronchopulmonary malformations (BPMs) consists of a broad spectrum of developmental abnormalities, ranging from abnormal lung with normal vasculature to abnormal vasculature with normal lungs and lesions with both parenchymal and vascular abnormalities. Terminology remains a problem, the use of descriptive approach is strongly supported in practice. The aim of our study was to assess the accuracy of computed tomography (CT) and magnetic resonance imaging (MRI) in classifying the different types of BPMs and to correlate this imaging with pathologic finding. Materials and methods We identified 24 patients reffered to our institution between years 2010 and 2015 with prenatal ultrasound (US) diagnosis of BPM, who had undergone surgical resection. Postnatal chest CT scans and fetal MRI of these patients formed the basis of our retrospective study. Two radiologists blinded to the histopathological results rewieved all CT and fetal MRI scans. Detected lesions were classified by predetermined criteria. These data were correlated with histopathological results. Results The significant diagnosis overlap of 71% (17 cases out of 24) between the CT and histology was observed. The significant diagnosis overlap between MRI and histology was observed of 80 % (8 cases out of 10). The diagnosis overlap of...
