Testo completoThis thesis studies the causes and consequences of the residential segregation process in the post-Apartheid South Africa.Inside this general issue, we are interested in several aspects still debated in the literature on residential segregation. Thefirst concerns the impact of individuals’ preferences for the racial composition of their neighborhood on the segregationlevels. The second question deals with the impact of residential segregation on the income levels of each racial group. Thelast issue is related to quantifying the different causes of segregation.Three chapters constitute this thesis. In the first chapter, we reconcile the theoretical literature on the impact of preferencesfor the racial composition of the neighborhood with the empirical evidences of declining levels of segregation in theUnited-States and South Africa. We argue that if individuals internalize the economic and social life that a new entrantbrings with him, then integrated neighborhoods can emerge. This effect is empirically stronger than homophilly andracism. In the second chapter, we study the impact of residential segregation on the whole income distribution. We showthat residential segregation has a positif effect on top incomes for Whites, whereas it has a negatif effect for Blacks at thebottom of the distribution. The effect of residential segregation is even more important than the effect of education inmost cases. In the third chapter, we quantify the impact of each determinant of segregation. We find that the lackof access to basic public services is the main determinant, whereas differences in sociodemographics only account for asmall part in the most segregated areas

Testo completoA la transició entre metafase i anafase els microtúbuls del fus mitòtic transporten els cromosomes a les cèl·lules filles, tot i això la separació completa dels braços dels cromosomes no succeeix fins al final dʼanafase. Amb lʼobjectiu dʼentendre com es resolen els cromosomes llargs durant anafase, hem creat una sèrie al·lèlica de cromosomes artificalment llargs. Amb aquesta metodologia hem demostrat que les cèl·lules que contenen cromosomes llargs estan sensibilitzades a la pèrdua de gens involucrats en lʼestructura i la segregació de cromosomes. Hem descobert que la Topoisomerasa II es necesària durant anafase per resoldre les regions distals de cromosomes llargs i que lʼactivitat de la polimerasa de microtúbuls, Stu2, és essencial en la resolució de concatenacions entre cromàtides germanes. A més, hem pogut identificar lʼorganització nuclear com una nova font que contribueix a lʼestrés topològic acumulat als cromosomes. En conclusió, les restriccions topològiques que imposen tant la longitud dels cromosomes com lʼarquitectura nuclear determinen la quantitat de concatenacions entre cromàtides germanes que han de ser resoltes per la Topoisomerasa II i els microtúbuls dinàmics durant anafase.

Testo completoConcrete pumping process is important in the construction sector, facilitating the transport of fresh concrete to the casting site, even in difficult-to-access areas. This technique enables the achievement of considerable heights and distances. However, this process presents challenges. Therefore, accurately predicting the pumpability of concrete appears to be essential. Indeed, concrete pumpability relies on its rheological properties and its ability to form a lubrication layer (LL) during its flow through pipes. Accordingly, it is worthy to mention that mastering the rheology of concrete and understanding the characteristics of the LL is important, especially considering that the mechanisms of LL formation remain not well understood.This project focuses on investigating Reynolds dilatancy (RD), a potential mechanism involved in LL formation, and aims to highlight the key parameters governing it. The first part of the study introduces the development of a new method to assess shear-induced variations (RD) at free-surface flow. This method, although more reliable for conventional vibrated concrete (CVC), it does not fully explore this mechanism. Consequently, a new empirical device, the CRD-Test, was designed to evaluate the RD of self-compacting concrete (SCC) subjected to various scenarios under free-surface and pressurized conditions, simulating real casting and pumping processes. In this second part of the study, SCC is considered as a biphasic mixture of coarser particles (> 1.25 mm) in a fluid matrix of fine mortar (< 1.25 mm). Moreover, the new experimental device, named CRD-Test, offers wide range of shear and pressure levels. It is based on a modified coaxial cylinder tribometer, with a rotational speed ranging from 0 to 3 rps, and an air pressure regulator from 0 to 300 kPa. The RD phenomenon is manifested by fluctuations in lateral pressure measured at the outer cylinder of this apparatus and it was investigated through new indices.Experimental results reveal that RD values were found to be in good agreement with the workability and design parameters of the investigated concrete mixtures. Concrete with low fluidity values exhibited high RD indices under both free-surface and pressurized shear conditions. Furthermore, a biphasic approach highlights correlations between RD and the characteristics of aggregates with a diameter greater than 1.25 mm, as well as the viscoplastic characteristics of the fine mortar (i.e., the suspending phase). Moreover, RD results are mainly affected by the relative packing density of coarse aggregate during pumping process. Finally, Reynold values were in good agreement with flow regime characteristics, particle dynamics, and shear-induced particle migration indices. According to established correlations, dynamic segregation can significantly influence the mechanisms of LL formation during concrete pumping at low shear rates, illustrating the importance of Reynolds dilatancy in this process. However, at higher shear rates, dynamic segregation has been observed to negatively impact RD values, thereby increasing the risk of blockage during concrete pumping
Bråmå, Åsa. "Studies in the Dynamics of Residential Segregation". Doctoral thesis, Uppsala University, Institute for Housing and Urban Research, 2006. http://urn.kb.se/resolve?urn=urn:nbn:se:uu:diva-6336.
Testo completoIn four scientific papers, this thesis investigates the processes, in terms of movements of individuals, that have produced, reproduced and transformed patterns of residential segregation in Swedish cities between 1990 and 2000.
Paper 1 examines processes of immigrant concentration, and the role of the Swedish majority population in these processes. Neighbourhood transition and mobility are described and analysed for a selection of residential areas that have experienced increased immigrant concentration. The results show that low in-migration rate among Swedes, rather than high out-migration rate, has been the main driving force behind the production and reproduction of immigrant concentration areas.
Paper 2 investigates the hypothesis that distressed neighbourhoods retain their character of distress through selective migration. The socio-economic situations of in-migrants, out-migrants and stayers in the distressed neighbourhoods of Stockholm are analysed and compared, and the results show the hypothesis to be confirmed. The people who move in are more likely to be unemployed and dependent on social benefits, and have on average lower incomes than those who move out and those who remain in the neighbourhoods.
Paper 3 further investigates the selective character of the out-migration from distressed neighbourhoods. One important conclusion is that the out-migration flow from the distressed residential areas is socio-economically and ethnically selective. When demographic and socio-economic differences are controlled for, the likelihood of leaving the distressed neighbourhoods is much lower for an immigrant than for a Swedish-born person.
Paper 4 examines the migration flows of a whole city, Göteborg. The paper deals with some of the most common questions within segregation research; the degree of spatial concentration of different ethnic groups, processes of concentration and dispersal, the role of the minority enclaves as ports of entry to the local housing market, and how this differs between ethnic groups.

Testo completoAt present, exclusive horizontal condominiums (EHC's) are the subject of debate since they represent and signify the urban-regional space of contemporary cities. These type of gated condominiums are considered new forms of socio-spatial segregation. The Metropolitan Coast of Aracaju (MCA) is a complex geographic object, a hybrid character phenomenon due to the confluence between the living and the holiday, old and new, urban and rural, public and private. This thesis is based on the argument that these new urban habitats are an element that acts directly on the reconfiguration of the urban-regional space and represent one of the features of diffuse urbanization in recent decades. The following methodological procedures in the research were used: reading the literature related to the theme; collection and organization of secondary data: documentary research, mapping and statistics; EIA-RIMAs and Master Plans analysis, as well as visits to the property developers web sites in order to observe how they operate in the promotion of real estate products; observation and photographic record in loco; interviews to the shareholders; preparation of cartographic materials; analysis and interpretation of data. The qualitative approach was chosen to explain the reality based on the principle of movement and geographical totality, considering that the processes acquire meaning when they take form, the form-content. This thesis aimed to analyze the socio-spatial dynamics of MCA focusing on exclusive horizontal condominiums. He attempted to explain the origin, the meaning, the intentions and the socio-spatial consequences of this form of segregation and specific real estate product within the regional urban context. The government, the housing market and the investors represent the force that act more directly in the expansion and proliferation of homes for first or second residence in this type of habitat and nesting on the coast or in the MCA field. Two moments of EHC's phenomenon of the MCA were identified. First, in the 1990s, with the emergence and expansion of beach condos in the coastal sector of Aracaju Expansion Zone for the participation of local real estate capital. And later, in the early twenty-first century, and still in the process of expansion, the regional real estate market, national and international begins to operate in specific sectors of the metropolitan coast in beachy sector of Barra dos Coqueiros and in the countryside of São Cristóvão. These condominiums present forms and offer complex content of activities and services. The location of these developments close to major structural axes implemented by the government, as the bridge Construtor João Alves, BR 101 road, now doubled, and state highways SE 100 and SE 050, makes the phenomenon a vector in the (re)structuring of spaces scattered and disconnected from the urban center of the capital. Property developers, representatives of local capital, regional, national and international, play a crucial role in the sale and marketing of real estate product that becomes increasingly a dream of consumption and a symbol of self-realization of solvables of the population. From the view of residents, the living and spend the holidays in these closed residential spaces were clarified the changes in socio-spatial practices that have established in metropolitan coast, and further it helps to explain the self-segregation process.
Os condomínios horizontais exclusivos (CHE’s) são, na atualidade, motivo de discussão pelo que representam e significam no espaço urbano-regional das cidades contemporâneas. Recortados fisicamente no espaço, os condomínios são considerados como novas formas de segregação socioespacial. No Litoral Metropolitano de Aracaju (LMA), o caráter híbrido do fenômeno, pelo confluir do morar e do veranear, do velho e do novo, do urbano e do rural, do público e do privado, dá o tom da complexidade deste objeto geográfico. A presente tese baseia-se na discussão que esses novos habitats urbanos configuram-se como um elemento que atua diretamente na reconfiguração do espaço urbano-regional em questão e que se constitui como uma das feições da urbanização difusa que se desenha nas últimas décadas. No processo de investigação da pesquisa foram utilizados os seguintes procedimentos metodológicos: levantamento e leitura da produção bibliográfica referente ao tema proposto para pesquisa; coleta e organização dos dados secundários: pesquisa documental, cartográfica e estatística; análise de EIA – RIMAS e Planos Diretores, assim como visitas ao site de incorporadoras a fim de observar como estas atuam na promoção dos produtos imobiliários; observação e registro fotográfico in loco; realização de entrevistas aos condôminos; elaboração de material cartográfico; análise e interpretação dos dados. Partiu-se do princípio do movimento e da totalidade geográfica pela compreensão de que os processos adquirem significado quando tomam forma, a forma-conteúdo. A abordagem se fez de forma mais qualitativa com foco na explicação dos processos que caracterizam o fenômeno dos CHE’s. A presente tese teve por objetivo analisar a dinâmica socioespacial do LMA com enfoque nos condomínios horizontais exclusivos. Buscou-se explicar a gênese, o significado, as intencionalidades e os desdobramentos socioespaciais desta forma de segregação e produto imobiliário específico dentro do contexto urbano regional. O poder público, o mercado imobiliário e os condôminos representam a força que atua mais diretamente na expansão e proliferação de residências para primeira ou segunda residência dessa forma de habitat e assentamento no litoral ou no campo do LMA. Identificou-se dois momentos do fenômeno dos CHE’s no LMA. Primeiro, na década de 1990, com o surgimento e a expansão dos condomínios de praia no setor costeiro da Zona de Expansão de Aracaju pela participação do capital imobiliário local. E posteriormente, no início do século XXI, e ainda em processo de expansão, o mercado imobiliário regional, nacional e internacional passa a atuar em setores específicos do litoral metropolitano, no setor praiano da Barra dos Coqueiros e na zona rural do município de São Cristóvão com o lançamento de condomínios com formas e conteúdos mais complexos diante da gama de atividades e serviços que estes dispõem. A localização destes empreendimentos próximos a importantes eixos estruturantes implantados pelo poder público, como a ponte Construtor João Alves, a BR 101, agora duplicada, e as rodovias estaduais SE 100 e SE 050, faz do fenômeno um vetor na (re)estruturação dos espaços dispersos e desconectados do núcleo urbano da capital. Os promotores imobiliários, representantes do capital local, regional, nacional e internacional, desempenham papel crucial na venda e comercialização deste produto imobiliário que se torna cada vez mais um sonho de consumo e um símbolo da autorrealização das camadas solváveis da população. O olhar dos condôminos elucidou as mudanças nas práticas socioespaciais que o morar e o veranear nestes espaços residenciais fechados tem implantado no litoral metropolitano e ajuda a explicar a autossegregação que se processa.

Testo completoIn this work we study a stochastic dynamic of particles of two types based on cells. Basically we incorporate some innovations on a one-dimensional model proposed and solved by R. da Silva et al. (Physica A, 2015) which considers that in the absence of particles of the opposite species in the cell a particle goes toward the next cell with probability p and returns to the previous cell with probability q = 1 p. However this motion probability linearly decreases with the relative density of the contrary species. Our work not only expands the problem for two dimensions but also includes collision aspects by adding scattering to the neighbouring cells. Our results are divided into two di erent categories: a) One of the species remain xed in their places which means that such particles will work as obstacles; b) Both species can move in the environment. In the rst situation we can observe, by monitoring the kurtosis, that an interesting transition of the crossing time distribution arises as the concentration of the obstacles increases. When both species can move we can observe that the distillation time (spent time for the complete geographical separation of the species in the corridor) depends on the parameter related to the perpendicular scattering of the particles. This same parameter has shown no in uence over the time distributions in the rst situation. Finally we implement periodic boundary conditions in the eld's direction. In this case we are able to observe the arising of band patterns parallel to the eld's direction exactly as it does with oppositely charged colloids under the in uence of a uniform electric eld or pedestrian dynamics in corridors. We also show how the system relax to such stationary state by using a suitable order parameter related to the particles segregation. Di erently from other pedestrian dynamics models, our model is not based on a Langevin-type equation. Our approach is totally stochastic and from this point of view, more fundamental and general to be extended to more types of models considering particles under counter ow. Our solution is obtained by both Monte Carlo simulations and numerical integration of partial di erential equations (PDE) from recurrence relation of the directed random walkers. The Monte Carlo simulations and the solutions of the PDE show a good agreement in all aspects analysed both qualitatively and quantitatively.

Testo completoRésumé : Récemment, il y a un grand intérêt à étudier les caractéristiques d'écoulement des suspensions dans différentes applications environnementales et industrielles, telles que les avalanches des neiges, les coulées de débris, les systèmes de transport et les processus d’écoulement des matériaux. En ce qui concerne les aspects rhéologiques, la plupart des suspensions, comme le béton frais, se comportent comme un fluide non-Newtonien. Le béton est le matériau de construction le plus largement utilisé dans le monde. En raison de limites qui caractérisent le béton normal en termes de maniabilité et de capacité de remplissage de coffrage, il était nécessaire de développer une nouvelle classe de béton qui peut couler sous son propre poids, en particulier à travers les zones congestionnées du coffrage. Par conséquent, le béton autoplaçant (BAP) est un nouveau matériau de construction qui est de plus en plus utilisé dans les différentes applications. Étant donné sa fluidité élevée de BAP peut être utilisé dans certaines applications particulières, notamment dans la section densément renforcée. Cependant, la fluidité élevée rend le béton plus sensible à la ségrégation des gros granulats pendant l'écoulement (la ségrégation dynamique) et ensuite au repos (ségrégation statique). La ségrégation dynamique peut augmenter lorsque le BAP est coulé sur une longue distance ou en présence d'obstacles. Par conséquent, il est toujours nécessaire d'établir un compromis entre la fluidité, la capacité de passage, et la stabilité du BAP. Ceci doit être pris en considération afin de concevoir le processus de coulée et dosage des mélanges du BAP. Ceci est appelé la conception d'ouvrabilité du BAP. Une conception de maniabilité efficace et non coûteuse peut être achevée à travers la e prévision et l'optimisation de l'ouvrabilité des mélanges de béton pour les procédés de construction sélectionnés, notamment le transport, le pompage, la mise en place, le compactage, la finition, etc. En effet, les formulations de mélange doivent se confirmer à la qualité de la construction demandée, par exemple les niveaux exigés de fluidité, la capacité de passage, la capacité de remplissage, et la stabilité (statique et dynamique). Celui est nécessaire pour développer des outils théoriques afin d’évaluer dans quelles conditions les exigences de qualité de la construction sont satisfaites. Cette thèse est consacrée à la réaliser des simulations analytiques et numériques pour prédire la performance d'écoulement du BAP dans différents procédés de la mise en place du béton. L'objectif spécifique de cette étude consiste à simuler l'écoulement du BAP dans essais empiriques, notamment la boite en L et la boite en T pour évaluer la performance du BAP pendent la mise en place (la fluidité, la capacité de passage, la capacité de remplissage, et la ségrégation dynamique induite par cisaillement ou par gravité). Par conséquent, le BAP est modélisé comme matériau hétérogène. En outre, un modèle analytique est proposé pour prédire la performance à l'écoulement du BAP dans la boite en L en utilisant la théorie de Dam Break. D'autre part, les résultats des simulations numériques de l’écoulement du BAP dans une poutre renforcée sont comparés aux résultats expérimentaux par des profils de surface libres. Les résultats des simulations numériques de BAP coulée (modélisée comme un fluide homogène unique), sont utilisés pour déterminer les zones critiques correspondant à des risques plus élevés de ségrégation et de blocage. Les effets des paramètres rhéologiques, la masse volumique, le contenu des particules, la distribution de barres d'armature, et les interactions particule-barres sur les performances d'écoulement du BAP sont évaluées à l'aide de simulations MFN d’écoulement du BAP par les essais des L-Box et T-box (modélisée comme une matériau hétérogène). Deux nouvelles approches sont proposées pour classifier les mélanges du BAP sur la base de la capacité de remplissage, et les propriétés de performabilité, en fonction de la fluidité, la capacité de passage et de la stabilité dynamique du BAP.

Testo completo[ES] En este trabajo se presenta un estudio de la influencia de la estructura química de los polímeros en su comportamiento térmico, mecánico y dieléctrico. Las técnicas experimentales empleadas para ello han sido la calorimetría diferencial de barrido, el análisis dinamo-mecánico y la espectroscopia dieléctrica. Adicionalmente, se han empleado otras técnicas como la difracción de rayos, con objeto de corroborar los resultados obtenidos por las primeras. En los Capítulos 1 y 2 se recoge la introducción y los objetivos, respectivamente. El Capítulo 3 presenta una breve descripción de las técnicas experimentales empleadas. En el Capítulo 4 se recogen los resultados obtenidos en el análisis comparativo de la respuesta a campos de perturbación eléctrica en un amplio rango de frecuencias y temperaturas para tres polimetacrilatos de bencilo con dos grupos dimetoxi en posiciones 2,5-, 2,3- y 3,4-. Los resultados obtenidos señalan el importante efecto de la posición de los grupos dimetoxi en el anillo aromático, sobre la dinámica molecular del polimetacrilato de bencilo. Los espectros obtenidos fueron muy complejos, por ello en orden a llevar a cabo un mejor análisis se emplearon métodos numéricos para la transformación tiempo-frecuencia que incluyeron el uso de técnicas de regularización paramétrica. Se ha estudiado el efecto que dicho cambio estructural ejerce tanto sobre los procesos de relajación secundaria como sobre el proceso de relajación α, relacionado con la transición vítrea. Así mismo, se ha analizado el efecto de la posición de los grupos dimetoxi en la formación de iii nanodominios en los que predominan las cadenas laterales, y su efecto en los procesos de conducción de los materiales analizados. En el Capítulo 5 se recoge el estudio de la conductividad de líquidos gomosos tomando como modelo el poli (metacrilato de 2,3-dimetoxibencilo), por su peculiar comportamiento. En este capítulo se ha realizado un análisis del principio de superposición tiempo-temperatura, empleando para ello diferentes variables relacionadas entre sí. En el Capítulo 6 se recoge el efecto de la presencia de entrecruzante en la movilidad molecular de polimetacrilatos que contienen residuos de éteres de alcoholes alifáticos. En este caso, se ha analizado el efecto de la presencia de entrecruzante tanto en los procesos de relajación secundarios, como en el proceso de relajación principal. También se llevó a cabo un análisis del efecto que la presencia de entrecruzante tiene sobre la creación de nanodominios gobernados por las cadenas laterales.

En el Capítol 5 s'arreplega l'estudi de la conductivitat de líquids gomosos prenent com a model el poli-(metacrilat de 2,3-dimetoxibencilo), pel seu peculiar comportament. En aquest capítol s'ha realitzat un anàlisi del principi de superposició temps-temperatura, emprant per a això diferents variables relacionades entre sí. En el Capítol 6 s'arreplega l'efecte de la presència d'entrecreuat en la mobilitat molecular de polimetacrilats que contenen residus d'èters d'alcohols alifàtics. En aquest cas, s'ha analitzat l'efecte de la presència d'entrecreuat tant en els processos de relaxació secundaris, com en el procés de relaxació principal. També es va dur a terme un anàlisi de l'efecte que la presència d'entrecreuat químic té sobre la creació de nanodominis governats per les cadenes laterals.

Testo completoLa ségrégation correcte des chromosomes est processus fondamental pour maintenir la stabilité génomique. Des défauts de ségrégation sont souvent à l’origine de l’apparition de cellules aneuploïdes, caractéristique fréquemment observée dans les cellules cancéreuses. Dans les cellules eucaryotes, la ségrégation correcte des chromosomes est assurée par le fuseau mitotique. Des mécanismes de contrôle, tels que le point de contrôle mitotique et le bon attachement des centromères, sont mis en œuvre pour assurer la bonne ségrégation des chromosomes. Dans cette étude, nous avons pu établir chez le levure fissipare, que la protéine csi2, localisée aux pôles du fuseau mitotique, joue un rôle sur la dynamique des MTs mitotiques, dans la formation d’un fuseau mitotique intègre et par conséquent dans la ségrégation correcte des chromosomes. Les MTs composants le fuseau mitotique bipolaire sont dynamiques et de petite taille ~1µm ce qui représente un défis technique pour les imager, en effet, la résolution optique d’un microscope ~λ/2 est en général de 300nm. Nous avons développé une nouvelle approche pour imager les MTs mitotiques basée sur l’utilisation du mutant réversible thermosensible kinesin-5 cut7. 24ts, pour obtenir des cellules ayant des fuseaux monopolaires. Ainsi, nous avons pu mettre en évidence que la délétion de la protéine csi2 chez la levure S. Pombe était à l’origine d’un allongement de la longueur des microtubules mitotiques, d’une augmentation du nombre de cellules présentant un fuseau monopolaire et d’une augmentation des défauts de ségrégation des chromosomes. L’étude de l’implication de la protéine csi2 dans ces différents mécanismes nous a permis de mettre en évidence la contribution de chacun de ces mécanismes dans la bonne ségrégation des chromosomes. Nous proposons dans cette étude que le facteur déterminant à l’origine d’une ségrégation incorrecte des chromosomes serait majoritairement imputable à des défauts de régulation de la dynamique des microtubules

Testo completoMatematiska modeller kan hjälpa oss att förstå många typer av sociala fenomen, som ryktesspridning, spridning av memes, gruppbeslut, segregation och radikalisering. Det finns idag otaliga modeller för sociala beteenden hos människor och djur, och fler presenteras kontinuerligt. Det stora antalet modeller försvårar navigering inom forskningsfältet, och många av modellerna är dessutom komplicerade och svåra att verifiera genom experiment. I detta arbete föreslås ett ramverk av grundläggande modeller, som var och en modellerar en aspekt av socialt beteende; det gäller sociala epidemier, cykler, gemensamt handlande, gruppbeslut, segregation och polarisering. Vi menar att dessa modeller utgör majoriteten av de verifierbara aspekter av socialt beteende som studeras, och att de bör behandlas som en utgångspunkt när en ny modell ska introduceras. Vilka av mekanismerna från utgångspunkten finns representerade i modellen? Skiljer den sig ens nämnvärt från utgångspunkten? Genom att ha en god förståelse för grundmodellerna, och genom att förklara på vilket sätt en ny modell skiljer sig från dem, kan forskare undvika att presentera modeller som i praktiken är mer komplicerade varianter av sådana som redan finns. I detta arbete visar vi hur dessa grundläggande modeller kan formuleras och studeras. Modellerna bygger på enkla regler om vad som händer när individer i en befolkning möter varandra. Till exempel, om en person som har vetskap om ett rykte träffar någon som inte har det, kan ryktet spridas vidare. Därför har antaganden om vilka personer som kan träffa varandra stor påverkan på de resultat som modellerna ger. I detta arbete studeras varje modell med två olika metoder: i den ena har alla personer i befolkningen samma sannolikhet att träffa varandra, i den andra representeras befolkningen av ett rutnät, där varje plats motsvarar en individ. I den senare har alltså varje person ett begränsat antal grannar att interagera med. Vilken av dessa två metoder man väljer har stor betydelse för vilka beteenden modellerna förutspår. Som ett komplement till detta arbete presenteras ett verktyg i form av ett Python-program som utför analysen av modellerna. Detta kan användas för att undersöka grundmodellerna som presenteras i detta arbete, men också för att formulera och analysera nya modeller på samma sätt. På det viset kan nya modeller enkelt jämföras mot grundmodellerna. Verktyget är användbart både som introduktion för de som är nya inom social dynamik, men också för de forskare som som vill ta fram nya modeller och föra forskningsfältet vidare.

Testo completoThe objective of this thesis is tuning the formation of ordered supramolecular structures of an H-bonded liquid alcohol, either by dispersion in an aprotic solvent or by confinement in mesoporous silicates (MCM-41 and SBA-15). In the bulk, a strong perturbation from ideal mixing depicted in terms of clustering between similar species is observed by small angle neutron scattering. Under confinement, a remarkable nanosegregation phenomenon of the mixture is observed in the pores, leading to concentric tubular structures of core-shell type, which are striking for macroscopically homogeneous and fully miscible binary systems. The molecular dynamics of these original glassforming nanostructures is studied by quasielastic neutron scattering in the liquid and vitreous states, revealing different types of relaxation modes under confinement with nontrivial concentration dependencies. Isotopic HD labelling of the mixtures components provides a unique comprehensive viewpoint on the properties of these confined binary liquids, establishing a direct correlation between spatially segregated dynamical heterogeneities and the formation of original core shell nanostructures induced by preferential interactions

Testo completoUsing Grauwins generalization [Ref. 3] of Schelling\'s segregation model we study, in a simplified model, some consequences of the \"fiscal war\" waged between the states of a federation, and of the rate tax generated by the recent Brazilian Central Bank regulation of bank credit portability. In Grauwins model the city is divided into blocks and all blocks have the same utility function, which measures the satisfaction of agents living there and depends on the density of agents. We introduced a disorder parameter in one of the blocks to make it more attractive than the others, in order to mimick the essential igredient of competition between states or banks. We first analyze an application of this model in the scenario of a fiscal war between the states of a nation. We interpret blocks as the states of a federation and economic agents as the industries (or people) who make decisions seeking to increase their own satisfaction. The fiscal war is an instrument used by some Brazilian states consisting in reducing taxes, subsidize land, provide infrastructure, etc in order to attract investment. This war at first can be beneficial for society as it contributes to the decentralization of the economy and reduces the differences of GDP and social discrepancies between states. Nationwide, however, the economic struggle between states usually results in loss of revenue at the global level. A vacated state, in order to attract agents already established elsewhere, need to give more incentives to attract investment because of its low population and consequently low utility. In this work we try to quantify the costs that states have with this kind of action. Another analysis of the results can be applied to a bank credit portability model, where we interpret economic agents as customers and blocks as retail credit banks. The interest rate levied on each bank will depend on the size of the portfolio of that bank. Having a bank with a differentiated interest rate makes it more attractive than others, and it begins to \"steal\" customers from other banks.However, those react and also reduce their rates, creating a \"war tax\" in the financial market. Studying the selfish scenario (where the government doesnt discourage a client from taking his/her debt to another bank), and assuming that the number of customers in the market is sufficiently small, the dynamics leads to a situation where we have just a few coexisting banks, the others having gone bankrupt. In the selfish limit the bank that was willing to give encouragement will have the largest portfolio while offering lower interest rates than the others, but this will be reversed as the government imposes a more altruistic behavior to the clients. We study analytically the effects, at the global level, of variations in the density, in the altruism parameter and in the parameter determining the utility function at saturation, as well as the effects of introducing disorder in one or more blocks. Finally, computer simulations were performed to check that the dynamic behavior in all scenarios was consistent with those obtained solutions.

EN : The dissertation focuses on the complex solution of the problem of energy efficiency of bulk materials agglomerating with consumption of solid fuel decrease by segregation processes controlling which allows to stabilize the thermal regime of granular material sintering by horizons of the layer during sintering of iron ore, bauxite materials, and firing of iron ore pellets. The scientific bases of increase of efficiency of fuel crushing process are further developed. In order to reduce the effect of erasing loads on the material, a new scheme of fuel crushing is reveal. The mathematical description of thermal processes in a stationary layer of mono - and polydisperse materials considering the internal sources of energy is implemented.

Testo completoÉs conegut en la literatura de neuroimatge que les xarxes cerebrals funcionals reflecteixen trets personals. Aquestes característiques individuals podrien interferir en caracteritzar la cognició entesa com la manera en què les xarxes es coordinen per realitzar una tasca, com mantenir l'atenció, recordar o processar informació visual. Cóm aquests aspectes individuals coexisteixen amb mecanismes generals, és, per tant, una pregunta clau en recerca sobre connectivitat cerebral. Aquest treball estudia la relació entre marcadors de connectivitat específics tant de subjectes, com de tasques. Se centra en dues escales temporals: la variabilitat entre sessions, i les fluctuacions ràpides produïdes durant una sessió d'adquisició. Utilitzem tècniques de machine learning per separar quantitativament les contribucions d'informació del subjecte i de l'estat cognitiu a la connectivitat. La metodologia presentada ens permet extreure aquelles xarxes representatives d'ambdues dimensions, així com aprofundir en la seva evolució, suggerint les escales temporals rellevants en la cognició.
There is consistent evidence in the neuroimaging literature that functional brain networks reflect personal traits. Individual specificity may interfere with the characterization of cognition, in terms of coordination of brain networks to perform a task, such as sustained attention, memory retrieval or visual information processing. How individual traits coexist with invariant mechanisms is, therefore, a key question in brain connectivity research. This work aims to examine the relationship between subject- and task-specific connectivity signatures. It focuses on two different timescales: day-to-day variability and faster fluctuations exhibited within a scanning session. We adopt a machine learning approach to quantitatively disentangle the contribution of subject information and cognitive state to the connectivity patterns. The proposed methodology allows us to extract the specific brain networks that support each of the two dimensions, as well as to delve into their changes over time, suggesting the relevant timescales for cognition.

Testo completoThis thesis presents an experimental and numerical study of the forces experienced by an object moving in granular media. This problem, which is of practical importance in many applications (robots, animal locomotion), is also of fundamental interest (rheology of granular materials, granular segregation). The experiment consists in a horizontal cylinder rotating around the vertical axis in glass beads. Both drag forces and lift forces experienced by the cylinder are measured.During the first half rotation, before the cylinder crosses its own wake, we measure a strong lift force (despite the symmetry of the object), about 20 times the buoyancy of the cylinder, and independent of its depth. Molecular dynamic simulations (Discrete Element Method) shed lights on how this lift force arises from the modification of the grain flow due to the pressure gradient in the medium. After several rotations, when the cylinder goes through its own wake, the drag force drops and becomes independent of depth. The rotation of the cylinder induces a structure in the granular packing, which screens the weight of the grains above it. Finally, a numerical study of forces on a large particle flowing with the granular medium is sketched, in relation with the phenomenon of granular segregation

Testo completoThis master´s thesis has as theme the action of real estate capital in the production of urban space in cities in the restructuring process. The study object is the production of residential buildings in Novo Hamburgo/Brazil in the period of 1983-2012. At this time, happened a biggest transformation of the productive base, which is historically related to the leather-footwear industry. The general objective of the research was analyze the city's real estate dynamics from the builders activities in the context of industrialization underway in the region. The supposition presented is that the current urban restructuring has reinforced the social-spatial segregation feature of the city, whose urbanization historically occurred inequality in space, according to its social stratification. The intention is to use the theory of production of urban space in capitalism to present a socioeconomic characterization of Novo Hamburgo in historical and regional context, and map the distribution of real estate investments in the city, checking the socio-spatial processes linked to the dynamics real estate in decades.
