O presente trabalho tem como objetivo analisar as mediações comunicativas da cultura que envolvem as inter-relações entre marcas e seus públicos interagentes em seus circuitos comunicacionais, assim como o processo de midiatização decorrente dessas relações. O sistema publicitário se adaptou às novas tecnicidades da sociedade contemporânea, somando à tradicional técnica da propaganda dispositivos promocionais que visam estabelecer vínculos com seus públicos interagentes por meio do estimulo à participação, interação e colaboração. Esse panorama reflete a mudança de enfoque de processos comunicacionais unilaterais, baseados na emissão de mensagens, para processos interacionais estabelecidos com o suporte de tecnicidades que permitem a produção de conteúdo e sua difusão em redes de informação, estimulando a interação entre marca e públicos em um processo comunicacional baseado na perspectiva da circulação da informação por circuitos comunicacionais. A tese analisa circuitos comunicacionais entre marcas e públicos a partir do uso de aplicativos dotados da tecnicidade do georreferenciamento como um recorte metodológico para demonstração das interações entre circuitos físicos e digitais de comunicação entre consumidores e marcas. Os circuitos físicos de consumo cultural de marca são analisados pela abordagem teórica da perspectiva da antropologia urbana de Magnani (1999) e pela óptica da teoria das mediações segundo Martín-Barbero (2010, 2001) e sob a perspectiva da midiatização em sua vertente nórdica segundo Hjarvard (2013), Hepp (2011) e pela visão latino-americana de Braga (2006), Fausto Neto (2010) e Trindade e Perez (2014); os circuitos digitais são analisados com base na noção de publicização de Casaqui (2011), assim como nas visões sobre compartilhamento e engajamento por Castells (2003), Saad Correa (2010), Recuero (2008), Ugarte (2008), Jenkins, Ford e Green (2014) e Terra (2011). O estudo resulta em um protocolo de análise de circuitos comunicacionais estabelecidos sob a mediação de lógicas de produção de marcas e táticas de recepção de consumidores em constante negociação. / This study aims to analyze culture communicative mediations that involves interrelationships between brands and interactor public in their communication circuits, as well as mediatization proceedings arising from these relations. Advertising system has adapted to new technicalities of contemporary society, adding to traditional technique of advertising some promotional devices that aim to establish links with their interactor public through stimulus to participation, interaction and collaboration. This situation reflects focus changes from unilateral communication processes based on message sending to interactional processes established by support of technicalities that enable content production and its distribution in information networks that stimulates interaction between brand and public in a communication process based on the perspective of information circulation on communication circuits. Thesis analyzes communication circuits between brands and public from use of georeferencing technicality provided mobile apps as a methodological cut to demonstration of interactions between physical and digital consumer-brands communication circuits. Brand cultural consumption physical circuits are analyzed by theoretical approach from Magnani´s (1999) urban anthropology perspective and Martin-Barbero´s (2010, 2001) mediation theory view and from mediatization theory by Hjarvard (2013) and Hepp´s (2011) northern perspective and latin american perspective of Braga (2006), Fausto Neto (2010) and Trinidad and Perez (2014).

Estimation of the fetal heart rate (FHR) has gained interest in the last century; low heart rate variability has been studied to identify intrauterine growth restricted fetuses (prepartum), and abnormal FHR patterns have been associated with fetal distress during delivery (intrapartum). Several monitoring techniques have been proposed for FHR estimation, including auscultation and Doppler ultrasound. This thesis focuses on the extraction of the non-invasive fetal electrocardiogram (NI-FECG) recorded from a limited set of abdominal sensors. The main challenge with NI-FECG extraction techniques is the low signal-to-noise ratio of the FECG signal on the abdominal mixture signal which consists of a dominant maternal ECG component, FECG and noise. However the NI-FECG offers many advantages over the alternative fetal monitoring techniques, the most important one being the opportunity to enable morphological analysis of the FECG which is vital for determining whether an observed FHR event is normal or pathological. In order to advance the field of NI-FECG signal processing, the development of standardised public databases and benchmarking of a number of published and novel algorithms was necessary. Databases were created depending on the application: FHR estimation with or without maternal chest lead reference or directed toward FECG morphology analysis. Moreover, a FECG simulator was developed in order to account for pathological cases or rare events which are often under-represented (or completely missing) in the existing databases. This simulator also serves as a tool for studying NI-FECG signal processing algorithms aimed at morphological analysis (which require underlying ground truth annotations). An accurate technique for the automatic estimation of the signal quality level was also developed, optimised and thoroughly tested on pathological cases. Such a technique is mandatory for any clinical applications of FECG analysis as an external confidence index of both the input signals and the analysis outputs. Finally, a Bayesian filtering approach was implemented in order to address the NI-FECG morphology analysis problem. It was shown, for the first time, that the NI-FECG can allow accurate estimation of the fetal QT interval, which opens the way for new clinical studies on the development of the fetus during the pregnancy.

In century XVI, an old Portuguese and colonial carnival arrived at Brazil colony brought by formers. From years 1970 of century XX, it occurred an inversion on those flows when Brazil started to export new languages, as of the school of samba (derived from the colonial Carnival) and soap operas. This process was after intensified the after the Revolution dos Cravos, a fact that was responsible for reopening the cultural and political boundaries of Portugal. This thesis analyzes this communicative circuit between Brazil and Portugal that start to characterize a species of context post-colonial of the lusophonie, understood in this research as being a media environment for the countries that use the Portuguese language. To compose the theoretical grating this work uses concepts from authors who argue about lusophonie (Cunha, 2005), the carnival (Bahkthin, 1998; Damatta, 1997), evolutive theories of culture (Katz & Greiner, 2004, 2005, 2009), processes of cultural hybridization (Canclini, 2001), post-colonials theories (Bhabha, 2003, Hall, 2003), semiotics (Santaella & Noth, the 2004) and communication (Mcluhan, 1997). The methodology understands bibliographical, internet, video and musical data the inquiry and its correlation with the other sources of information, proceeding from the contact with the schools of samba in Portugal, made possible for the research of field that was carried through with the support of the University of the Minho, in cities and Portuguese villages that practice the carnival ritual. The main results is about the conclusion that the imitation of the Brazilian parades in the foreign environment of Portugal is a complex process and sets in motion what this if calling "market of languages . This market of languages represents an inversion of sensible in the habitual circuits, therefore Brazil, the former-colony, now is exporting languages to the former-metropolis: schools of samba, soap opera, etc. The unfolding of this quarrel can be identified in debates of authors as Boaventura de Souza Santos whose project of research ALICE (2011) argues that Europe needs to recognize itself in the mirrors of the worlds that helped to create. In this inquiry, it is considered, therefore, that in market of languages between Brazil and Portugal, the samba schools, as process derived from the colonial Carnival, is a possible metaphor of these mirrors / Esta investigação tem como objeto de estudo a linguagem dos desfiles de escola de samba nos fluxos comunicativos entre Brasil e Portugal. No século XVI, a antiga brincadeira carnavalesca portuguesa do Entrudo chegou ao Brasil colônia trazida pelos colonizadores. A partir dos anos 1970 do século XX, o jogo se inverteu quando o Brasil começou a exportar novas linguagens, como a da escola de samba (derivada do antigo Entrudo) e as telenovelas. Este processo foi intensificado após a Revolução dos Cravos, responsável pela reabertura política e cultural de Portugal. Esta tese analisa justamente este circuito comunicativo entre Brasil e Portugal, que passa a caracterizar uma espécie de contexto pós-colonial da lusfonia, entendida nesta pesquisa como sendo um ambiente midiático para os países que utilizam a língua portuguesa. Para compor a grade teórica são analisadas as obras de autores que discutem a lusofonia (Cunha,2005), o carnaval (Bahkthin, 1998; Damatta, 1997), as teorias evolutivas da cultura (Katz &Greiner, 2004, 2005, 2009), os processos de hibridação cultural (Canclini, 2001), as teorias pós-coloniais (Bhabha, 2003, Hall,2003), a semiótica (Santaella & Noth,2004) e a comunicação (Mcluhan,1997). A metodologia compreende a investigação bibliográfica, webgráfica, videográfica e fonográfica e sua correlação com as outras fontes de informação, provenientes do contato com as escolas de samba em Portugal, viabilizado pela pesquisa de campo que foi realizada com o apoio da Universidade do Minho, em cidades e aldeias portuguesas que praticam os festejos carnavalescos. Os principais resultados dizem respeito à constatação de que a imitação dos desfiles brasileiros no ambiente estrangeiro de Portugal é um processo complexo e aciona o que esta se chamando de "mercado de linguagens . Este mercado de linguagens representa uma inversão de sentido nos circuitos habituais, pois o Brasil, a ex-colônia, agora esta exportando linguagens para a ex-metrópole: escolas de samba, telenovela, etc. Os desdobramentos desta discussão podem ser identificados em debates de autores como Boaventura de Souza Santos cujo projeto de pesquisa ALICE (2011) discute que a Europa precisa se reconhecer nos espelhos dos mundos que ajudou a criar. Nesta investigação, considera-se, portanto, que no mercado de linguagens entre Brasil e Portugal, as escolas de samba, como processo derivado do antigo Entrudo colonial, sejam uma metáfora possível destes espelhos

Krivelevich and Patkós conjectured in 2009 that χ(G(n, p)) ∼ χ=(G(n, p)) ∼ χ∗=(G(n, p)) for C/n < p < 1 − ε, where ε > 0. We prove this conjecture for n−1+ε1 < p < 1 − ε2 where ε1, ε2 > 0. We investigate several measures that have been proposed to indicate centrality of nodes in networks, and find examples of networks where they fail to distinguish any of the vertices nodes from one another. We develop a new method to investigate core-periphery structure, which entails identifying densely-connected core nodes and sparsely-connected periphery nodes. Finally, we present an experiment and an analysis of empirical networks, functional human brain networks. We found that reconfiguration patterns of dynamic communities can be used to classify nodes into a stiff core, a flexible periphery, and a bulk. The separation between this stiff core and flexible periphery changes as a person learns a simple motor skill and, importantly, it is a good predictor of how successful the person is at learning the skill. This temporally defined core-periphery organisation corresponds well with the core- periphery detected by the method that we proposed earlier the static networks created by averaging over the subjects dynamic functional brain networks.
