Повний текст джерелаNo período de 27/04/1995 a 26/04/2005, estudou-se as vítimas de lesões de causa externa atendidas no Ambulatório de Ortopedia Pediátrica do Hospital Maria Amélia Lins. Os objetivos foram identificar as características das lesões ortopédicas; o perfil dos pacientes quanto às variáveis: idade, gênero, mecanismo de trauma, tipo de lesão, lado, localização topográfica e afecções associadas; e comparar os dados epidemiológicos com os da literatura. Foram critérios de inclusão ser vítimas de lesões de causa externa, a localização do prontuário, oregistro nele dos dados necessários à pesquisa, e a presença de fise aberta. No período, foram identificados 2472 pacientes, dos quais 1199 se encaixavam nos critérios de inclusão. Foram extraídos dos prontuários dados de identificação do paciente e dados relativos às lesões observadas. A variável idade foi registrada em números absolutos de anos de vida. Os mecanismos de trauma foram agrupados em acidentes de trânsito; quedas; trauma direto;outros e sem relato. Os tipos de lesões foram subdivididos em amputações; fraturas; epifisiólise; luxações; traumatismo cranioencefálico; contusões; lesões de órgãos internos; lesões de face; e outras lesões. As fraturas, fraturas-luxações, as epifisiólises e luxações foram classificadas, quanto à exposição, em expostas e fechadas. A localização topográfica das lesões foi classificada em relação aos segmentos ósseos nos quais ocorreram. Os pacientes foram agrupados em amostra geral, portadores de lesões isoladas e portadores de lesões múltiplas, considerando-se essas últimas as que acometeram mais de um segmento do esqueleto e/ou lesões de outros órgãos ou sistemas. A lesão musculoesquelética que necessitou mais atenção secundária foi descrita como lesão principal. Da amostra geral, 838 (68,9%) pacientes tiveram lesões isoladas e 361 (30,1%) presentaram 884 lesões. A média de idade foi 7,6±3,4 anos. Houve predomínio do gênero masculino e do lado esquerdo. Os membros superiores preponderaram nas lesões isoladas e os membros inferiores nas lesões múltiplas. O mecanismo de trauma mais comum na amostra geral e no grupo lesões isoladas foi a queda(39,0% e 44,3% respectivamente) e, nas lesões múltiplas, foi o acidente de trânsito (42,7%). O tipo de lesão mais frequente foi a fratura (73,0% - amostra geral, 85,3% - lesões isoladas e 61,1% - nas múltiplas). Quanto à localização topográfica, nas lesões isoladas predominaram asfraturas de cotovelo (24%) e, nas lesões múltiplas, as fraturas dos ossos da perna (12,9%). Nos portadores de lesões múltiplas, 67,1% tinham uma lesão associada, 24,3% duas, 5,3% três, e 3,3% quatro, com destaque para as fraturas de cotovelo com as fraturas de antebraço (25 casos). Concluiu-se que as características descritivas se encontram em conformidade com aliteratura. Os portadores de lesões isoladas podem ser definidos como meninos em idade escolar, vítimas de queda, apresentando fratura fechada de osso longo do membro superior. Os portadores de lesões múltiplas caracterizaram-se por ser meninos, em idade escolar, vítimas de acidente de trânsito apresentando fratura de ossos do membro inferior acompanhada de outra lesão. O desenvolvimento e a implantação de protocolos deatendimento são de fundamental importância para a eliminação de vieses na coleta de dados nesse tipo de estudo.

Повний текст джерелаState-of-the-art traffic data sources like Car-to-Infrastructure communication, Floating Car Data and video detection offer great new prospects for vehicle-actuated traffic signal control. Due to this, the article deals with a recent approach which uses vehicles’ delay times for real-time control of traffic signals at an isolated intersection. One of the strengths of the new approach is that it can handle also incomplete data sets, e.g. caused by low penetration rates of vehicles equipped with Car-to-Infrastructure communication technology, in an appropriate manner. Based on a microscopic simulation study the high quality of this innovative approach is demonstrated, which is equal or even outperforms the well-known headway-based control. However, a decreasing penetration rate of equipped vehicles means a reduced quality of signals’ control, which is quantified in the microscopic simulation study, too, and provides useful information for tests in the field

Este trabalho investiga o uso de um modelo usando Latent Semantic Analysis (LSA) na avaliação automática de respostas curtas, com média de 25 a 70 palavras, de questões discursivas. Com o surgimento de ambientes virtuais de aprendizagem, pesquisas sobre correção automática tornaram-se mais relevantes, pois permitem a correção mecânica com baixo custo para questões abertas. Além disso, a correção automática permite um feedback instantâneo e elimina o trabalho de correção manual. Isto possibilita criar turmas virtuais com grande quantidade de alunos (centenas ou milhares). Pesquisas sobre avaliação automática de textos estão sendo desenvolvidas desde a década de 60, mas somente na década atual estão alcançando a acurácia necessária para uso prático em instituições de ensino. Para que os usuários finais tenham confiança, o desafio de pesquisa é desenvolver sistemas de avaliação robustos e com acurácia próxima de avaliadores humanos. Apesar de alguns estudos apontarem nesta direção, existem ainda muitos pontos a serem explorados nas pesquisas. Um ponto é a utilização de bigramas com LSA, mesmo que não contribua muito com a acurácia, contribui com a robustez, que podemos definir como confiabilidade2, pois considera a ordem das palavras dentro do texto. Buscando aperfeiçoar um modelo LSA na direção de melhorar a acurácia e aumentar a robustez trabalhamos em quatro direções: primeira, incluímos bigramas de palavras no modelo LSA; segunda, combinamos modelos de co-ocorrência de unigrama e bigramas com uso de regressão linear múltipla; terceira, acrescentamos uma etapa de ajustes sobre a pontuação do modelo LSA baseados no número de palavras das respostas avaliadas; quarta, realizamos uma análise da distribuição das pontuações atribuídas pelo modelo LSA contra avaliadores humanos. Para avaliar os resultados comparamos a acurácia do sistema contra a acurácia de avaliadores humanos verificando o quanto o sistema se aproxima de um avaliador humano. Utilizamos um modelo LSA com cinco etapas: 1) pré- processamento, 2) ponderação, 3) decomposição a valores singulares, 4) classificação e 5) ajustes do modelo. Para cada etapa explorou-se estratégias alternativas que influenciaram na acurácia final. Nos experimentos obtivemos uma acurácia de 84,94% numa avaliação comparativa contra especialistas humanos, onde a correlação da acurácia entre especialistas humanos foi de 84,93%. No domínio estudado, a tecnologia de avaliação automática teve resultados próximos aos dos avaliadores humanos mostrando que esta alcançando um grau de maturidade para ser utilizada em sistemas de avaliação automática em ambientes virtuais de aprendizagem.
This work investigates the use of a model using Latent Semantic Analysis (LSA) In the automatic evaluation of short answers, with an average of 25 to 70 words, of questions Discursive With the emergence of virtual learning environments, research on Automatic correction have become more relevant as they allow the mechanical correction With low cost for open questions. In addition, automatic Feedback and eliminates manual correction work. This allows you to create classes With large numbers of students (hundreds or thousands). Evaluation research Texts have been developed since the 1960s, but only in the The current decade are achieving the necessary accuracy for practical use in teaching. For end users to have confidence, the research challenge is to develop Evaluation systems that are robust and close to human evaluators. despite Some studies point in this direction, there are still many points to be explored In the surveys. One point is the use of bigrasms with LSA, even if it does not contribute Very much with the accuracy, contributes with the robustness, that we can define as reliability2, Because it considers the order of words within the text. Seeking to perfect an LSA model In the direction of improving accuracy and increasing robustness we work in four directions: First, we include word bigrasms in the LSA model; Second, we combine models Co-occurrence of unigram and bigrams using multiple linear regression; third, We added a stage of adjustments on the LSA model score based on the Number of words of the responses evaluated; Fourth, we performed an analysis of the Of the scores attributed by the LSA model against human evaluators. To evaluate the We compared the accuracy of the system against the accuracy of human evaluators Verifying how close the system is to a human evaluator. We use a LSA model with five steps: 1) pre-processing, 2) weighting, 3) decomposition a Singular values, 4) classification and 5) model adjustments. For each stage it was explored Strategies that influenced the final accuracy. In the experiments we obtained An 84.94% accuracy in a comparative assessment against human Correlation among human specialists was 84.93%. In the field studied, the Evaluation technology had results close to those of the human evaluators Showing that it is reaching a degree of maturity to be used in Assessment in virtual learning environments.

Повний текст джерелаTiivistelmä Kaupalliset long-term evolution (LTE) -verkot tarjoavat nopean, edullisen ja alueellisesti kattavan pääsyn Internettiin sekä laajaan valikoimaan sovelluksia. Samaan aikaan turvallisuustoimijat (public safety (PS) -toimijat) käyttävät vanhanaikaisia äänen sekä vaatimattoman datayhteyden tarjoavia verkkoja. LTE-verkot ovat kuitenkin äskettäin standardoitu tarjoamaan valmiudet myös toimintokriittiseen kommunikointiin. Toisaalta, kaupalliset LTE-verkot eivät vielä tarjoa esimerkiksi tarvittavaa alueellista kattavuutta PS-käyttäjille. Lisäksi, kaupalliset verkot saattavat olla epäkunnossa kriittisissä tilanteissa. Tämän vuoksi PS-toimijat tarvitsevat omia nopeasti pystytettäviä LTE-verkkoja tukemaan nykyaikaista viestintäänsä. Opinnäytetyössä tutkitaan näiden nopeasti pystytettävien LTE-verkkojen käyttöä kaupallisten LTE-verkkojen kanssa. Keskeiset tehtävät ovat eri verkkojen PS-toimijoiden saumaton yhdistäminen sekä verkkojen taajuusjaon toteuttaminen. Tämä opinnäytetyö tarjoaa käytännön ratkaisuja verkkojen yhteentoimivuuden takaamiseksi ja radiotaajuuksien jakoratkaisuja lisensoidun jaetun käyttöoikeuden licensed shared access (LSA) -metodin avulla. Vaikka LSA:n käsite on jo pitkälle kehitetty, sitä ei ole tutkittu perusteellisesti PS-toimijoiden näkökulmasta ottaen huomioon heidän erityisvaatimuksensa. Tässä työssä syvennytään näiltä osin LSA järjestelmään yhtenä vaihtoehtona taajuuksien saamiseksi nopeasti pystytettäville verkoille. Lisäksi työssä kehitetään robusti LSA-pohjainen taajuuksien jakamisjärjestelmä nopeasti pystytettäville verkoille tilanteissa, joissa kaupalliset verkot ovat riittämättömät. Huomaa, että PS-toimijoiden on pystyttävä hyödyntämään taajuuksia myös silloin, kun LSA-järjestelmän kaikki osat eivät ole käytettävissä ja kun kaupallinen LTE järjestelmä on alhaalla. Tätä varten opinnäytetyössä kehitetään LSA:ta täydentävä havainnointimenetelmä, jolla taataan taajuustiedot vapaista taajuuksista nopeasti pystytettäville verkoille, sekä näytetään, miten PS-toimijat voivat hyödyntää LSA:ta toissijaisen taajuuslisenssin avulla. Tämä on hyvä vaihtoehto radiospektrin varaamiseksi kokonaan. Työ kokoaa puuttuvia osia olemassa oleviin menetelmiin, jotta voidaan varmistaa kaupallisten verkkojen toimivuus PS-käyttäjille yhdessä niitä tukevien nopeasti pystytettävien verkkojen kanssa taajuuksien käytön ja sovelluspalvelujen osalta

Повний текст джерелаAquesta tesi ofereix una descripció i una anàlisi sintàctica per a la coordinació i el “gapping” en coordinació conjuntiva en llengua de signes catalana (LSC), dins el marc generativista i minimista. Pel que fa a la coordinació, la categoria sintàctica que es proposa és “Coordination Phrase” (CoP) per a la coordinació conjuntiva, disjuntiva i adversativa. A l’estructura, ramificada a la dreta, els constituents de la conjunció són especificadors i complements de CoP. La derivació per a cada tipus de coordinació s’aplica a partir d’aquest model. Pel que fa al “gapping”, mostra proprietats similars a l’el·lipsi de SV (VP-ellipsis), sobretot perquè pot aparèixer en subordinació. A més, la l’existència només d’un abast distribuït de la negació (¬A&¬B) i la presència de tòpic i focus contrastius mostra la necessitat de tenir una coordinació “àmplia” on els dos conjunts siguin CPs. En la derivació de “gapping”, els arguments es mouen a TopP i FocP, seguits de l’eliminació del TP a PF, ambel tret [E] posicionat al nucli de FocP.

Повний текст джерелаThis work contains the first description of Catalan Sign Language (LSC) Relative Clauses (RCs). Also, it proposes an analysis within the Generative framework that takes a typological approach. Regarding the syntactic typology of LSC RCs, they are circumnominal. In other words, they show the pivot (or antecedent) inside the RC. This contrasts with the most common RCs in Indo-European languages, the adnominal ones, in which the pivot appears outside the RC, that is, in the matrix clause. Other evidence that supports the idea that RCs in LSC are circumnominal is put forward. For instance, this structure shows a determiner that nominalizes the whole construction, as usually found in circumnominal RCs across languages. Circumnominal RCs in LSC never appear in its basic position inside the matrix clause. They have to appear or fronted or postposed to the matrix one. This same distribution is also found in other sign language RCs, for instance, in Italian Sign Language (LIS). The analysis presented here essentially follows the raising one (Kayne 1994). However, I have added some modifications in order to take into account crucial LSC data. The resulting analysis can be applied to the circumnominal construction as a whole, that is, in both oral and signed languages. To sum up, this work is a contribution to both typology and theoretical linguistics.

Aquesta tesi descriu les estratègies morfofonològiques utilitzades als pronoms personals de la llengua de signes catalana (LSC) per a codificar aquestes distincions. En resum, es proposa que les categories de persona i nombre s’expressen utilitzant dues estratègies interrelacionades: la persona s’expressa a través de trets espacials (localitzacions a l’espai sígnic definides en relació amb el cos del parlant), el nombre es marca gramaticalment a través d’especificacions en la trajectòria del signe (moviments que connecten localitzacions espacials). La combinació d’aquestes dues operacions es tradueix en la codificació formal de tres distincions de persona (amb una oposició addicional entre exclusivitat, inclusivitat mínima i inclusivitat augmentada en la primera persona) i quatre valors de nombre (singular, dual, paucal i plural).

Повний текст джерелаThis thesis focuses on the identification and description of the category verb (V) in Catalan Sign Language (LSC). The research has been developed within the Borer’s theoretical framework (basically 2005a and 2005b), which has provided an approach to LSC different from the one typically found in previous descriptive studies. We describe the Lexical Functors (FL) and Functional Functors (FF) that we have identified for the category V in LSC in the corpus of our study. Following other investigations in sign languages, the present study starts with an analysis of a set of name-verb pairs in LSC, and we identify their morphophonological differences. At this level of morphophonological differences we distinguish two FL that assign an eventive structure to the root and identify it as V-equivalent. We also analyse the set of FF ( and independent f-morph) that may cause morphophonological changes in the verbalized root and contribute to identifying the category V. In this sense, the Functional Projections that are described in this thesis on the category V in LSC are: Agreement, Aspect, Manner and Quantity. Concerning Agreement, we analyse Person Agreement, Spatial Agreement and Number Agreement in LSC from a syntactic perspective. In contrast to most studies on Agreement in signed languages, we highlight the role of location as a part of the of the Person Agreement Functional Projection, even in roots classified as ‘plain roots’. We show that there is a hierarchical order that reflects Agreement with arguments and that depends on different syntactic structures. With respect to Aspect, we argue that ‘telicity’ and ‘atelicity’ are defined as Quantity, according to Borer (2005a,b), and that Aspect is built in syntax. Concerning the two FL identified for verbal roots, we show that one of them (FL1) assigns non-quantity eventive information to the verbalized root and the other (FL2#) a quantity one. We argue that this lexical eventive information is not crucial in syntax, first, because it can be modified, and, second, because verbalized roots can appear in different syntactic contexts, no matter which is its initial morphophonologycal information. Finally, in this study we show the need of a Manner Functional Projection and a Quantity Functional Projection (different from FL) to identify the category V in LSC. They both force a number of morphophonological changes in the V-equivalent roots and, consequently, they help to identify the category V. For each of them, we describe the relevant found in the corpus we have analysed, their different morphophonological realizations and the restrictions they may have.

Повний текст джерелаWith the growing popularity of GitHub, the largest host of source code and collaboration platform in the world, it has evolved to a Big Data resource offering a variety of Open Source repositories (OSR). At present, there are more than one million organizations on GitHub, among them Google, Facebook, Twitter, Yahoo, CRAN, RStudio, D3, Plotly and many more. GitHub provides an extensive REST API, which enables scientists to retrieve valuable information about the software and research development life cycles. Our research pursues two main objectives: (I) provide an automatic OSR categorization system for data science teams and software developers promoting discoverability, technology transfer and coexistence; (II) establish visual data exploration and topic driven navigation of GitHub organizations for collaborative reproducible research and web deployment. To transform Big Data into value, in other words into Smart Data, storing and processing of the data semantics and metadata is essential. Further, the choice of an adequate text mining (TM) model is important. The dynamic calibration of metadata configurations, TM models (VSM, GVSM, LSA), clustering methods and clustering quality indices will be shortened as "smart clusterization". Data-Driven Documents (D3) and Three.js (3D) are JavaScript libraries for producing dynamic, interactive data visualizations, featuring hardware acceleration for rendering complex 2D or 3D computer animations of large data sets. Both techniques enable visual data mining (VDM) in web browsers, and will be abbreviated as D3-3D. Latent Semantic Analysis (LSA) measures semantic information through co-occurrence analysis in the text corpus. Its properties and applicability for Big Data analytics will be demonstrated. "Smart clusterization" combined with the dynamic VDM capabilities of D3-3D will be summarized under the term "Dynamic Clustering and Visualization of Smart Data via D3-3D-LSA".

Повний текст джерелаAquesta tesi se centra en l’ús de l’espai en llengua de signes catalana (LSC) a nivell discursiu. Defenso que les localitzacions no descriptives s’estableixen en els tres plans espacials i en descric els trets gramaticals. Les localitzacions espacials es representen morfofonològicament amb un punt abstracte a l’espai que no té una direcció específica en els plans espacials i que s’interpreta categòricament en el sistema lingüístic. En LSC, el pla frontal és gramaticalment important i denota especificitat: les localitzacions baixes correlacionen amb especificitat, mentre que les localitzacions altes correlacionen amb no especificitat. A més, la incorporació de l’estructura del discurs a l’anàlisi demostra que les localitzacions espacials baixes també denoten prominència discursiva. Les localitzacions espacials són, per tant, part de la gramàtica de la LSC i aquí les analitzo en relació al rol que tenen en l’expressió de l’especificitat i l’estructura discursiva. L’anàlisi s’emmarca en la formalització de la Discourse Representation Theory, tot basant-se en les dades d’un corpus en LSC a petita escala.

Повний текст джерелаDen avsevärda ökningen av den mobila datatrafiken har skapat stor belastning på de trådlösa mobilnäten. I den nuvarande mycket konkurrensutsatta marknaden, måste mobiloperatörerna (MNO) sträva efter att skapa ytterligare kapacitet i deras nätverk, samtidigt som de måste tänka på kostnadsfaktorerför att göra sin verksamhet hållbar. Tillsammans med framsteginom spektrumeffektiv teknik och driftsättning av små basstationer, ha rman fått fram kostnadseffektiva metoder för att öka kapaciteten för inom- och utomhusanvändare. Fördelen av bättre spektrumanvändning för frekvenser under 6 GHz och opportunistiska tillgång av spektrum, har motiverat utbyggnaden av trådlösanätverk. Detta möjliggör för mobila nätverk att använda spektrumet genom att samexistera med etablerade användare och tekniker. Två nya kompletterande spektrumtillstånd har lockat industrin och den akademiska världen, Licensed Shared Access (LSA) och License Assisted Access (LAA). I denna avhandling, har de tekno-ekonomiska aspekterna av LSA och LAA regimer undersökts och jämförts. Dynamiken av drift i olicensierat spektrum representeras i scenariot av två mobilnätsoperatörer samexisterar och följer lagkraven. Resultaten indikerar att valet av lämplig mekanism t.ex. val av rätt kanal är av stor betydelse vid användning av olicensierad regim (LAA). Resultatentyder på att LAA kan vara ett alternativ för kostnadseffektiv distributionsmetod i vissa scenarier, till exempel när det finns en låg eller måttlig tillgång på LSA bandbredd. För det framtida arbetet, föreslår vi en optimerad användarassociation till de små cellerna för att ge en bättre lastbalansering mekanism.

Повний текст джерелаThe study of corporate directors civil liability in national doctrine usually deals with fiduciaries duties, regular management act and the ultra vires theory, directors malpractice or deceit, ut universi and ut singuli actions and solidarity between directors and companies responsibility. Few address the extinctive causes of such liability, and rare are those who address the liability exclusion hypothesis of the Article 159, § 6º, of the Law n. 6.404/76. Whereas that the fiduciary duties discipline provided for in Brazilian corporate law has strong influence of American law, was sought in the legislation, doctrine and jurisprudence of that country the fundamentals for a better understanding and application of the exclusion rule and, particularly, in the business judgment rule, a doctrine that protects directors against liability for damages to the company arising from their acts, protection also afforded by the Article 159, § 6º, of the Law n. 6.404/76, to the loyal and good faith director.

Повний текст джерелаBiTAK-BiLTEN are used for the implementation of different orbit determination algorithms concluding to an estimate of the satellite&rsquo
s state. Satellite&rsquo
s position, velocity components and the GPS receiver&rsquo
s clock bias are selected as the state parameters to be estimated. Kalman filter algorithms are used for the estimation of these state parameters. The modeled affecting force components include
geopotential and atmospheric drag. The global gravity models EGM96 and EIGEN-CG03C have been utilized together with Harris Priester atmospheric density model for the force modeling. The effect of the changes during the implementation of the force models, numerical integration, and estimation algorithms are investigated. Software has been developed using MATLAB programming language for the implementation of all algorithms performed in this study for orbit determination.

Liver fibrosis is the wound healing response to repeated injury of the liver. This process begins with the damage of the parenchymal cells and subsequent inflammation, characterized by the rupture of the hepatic architecture associated to the increase of the expression of the components of the extracellular matrix. The development of hepatic fibrosis is based on the activation of hepatic stellate cells (HSC) that undergo phenotypic changes and are characterized by loss of vitamin A deposition and increased cell proliferation, triggering hepatic microcirculatory dysfunction and fibrogenesis in patients with chronic liver disease (CLD). Liraglutide is a GLP-1 agonist (glucagon-like peptide 1) well established as an antidiabetic drug, but also has anti-inflammatory properties, in addition to the effectiveness for NAFLD (non-alcoholic fatty liver disease). Therefore, the aim of this study was to evaluate the effects of liraglutide on the HSC phenotype and liver microvascular function using diverse pre-clinical models of CLD. The results obtained demonstrate that Liraglutide de-activated human and rat HSC phenotype through a GLP1-Rindependent mechanism. Liraglutide did not affect the HSC viability but decreased cell proliferation. CLD-rats receiving liraglutide exhibited significantly lower portal pressure (-20%) with a consequent reduction in intrahepatic vascular resistance. There was also a marked improvements in hepatic vascular function, fibrosis, HSC phenotype and sinusoidal endothelial phenotype. The anti-fibrotic effects of liraglutide were confirmed in human liver tissue. In conclusion, this study demonstrates for the first time that liraglutide improves hepatic sinusoidal endothelium in clinically relevant experimental models of cirrhosis, which leads to improvement in fibrosis and portal hypertension, and therefore is valid in the treatment of advanced chronic liver disease.
A fibrose hep?tica ? a resposta cicatricial do f?gado ? les?es repetidas. Este processo inicia com o dano das c?lulas parenquimatosas e consecutiva inflama??o, caracterizado pelo rompimento da arquitetura hep?tica associada ao aumento da express?o dos componentes da matriz extracelular. O desenvolvimento da fibrose hep?tica ? baseado na ativa??o das c?lulas hep?ticas estreladas (HSC) que sofrem mudan?as fenot?picas e se caracterizam pela perda do dep?sito de vitamina A e aumento da prolifera??o celular, desencadeando disfun??o microcirculat?ria hep?tica e fibrog?nese nos pacientes com doen?a hep?tica cr?nica (CLD). A liraglutida ? um an?lago do GLP-1 (glucagon-like peptide 1) bem estabelecido como f?rmaco antidiab?tico, mas que tamb?m possui propriedades antinflamat?rias, al?m da efetividade para NAFLD (doen?a hep?tica gordurosa n?o alco?lica). Por essa raz?o, o objetivo deste estudo foi avaliar os efeitos da liraglutida sobre o fen?tipo das HSC e a fun??o microvascular hep?tica utilizando diversos modelos pr?-cl?nicos de CLD. Os resultados obtidos demonstram que a liraglutida desativou o fen?tipo das HSC humanas e de ratos atrav?s de um mecanismo independente do receptor GLP1. A liraglutida n?o afetou a viabilidade das HSC mas diminuiu a prolifera??o celular. Os ratos com CLD que receberam liraglutida apresentaram press?o portal significativamente menor (-20%) com consequente redu??o da resist?ncia vascular intra-hep?tica. Houve tamb?m uma acentuada melhoria na fun??o vascular hep?tica, fibrose, fen?tipo das HSC e fen?tipo endotelial sinusoidal. Os efeitos anti-fibr?ticos da liraglutida tamb?m foram confirmados em tecido hep?tico humano. Como conclus?o, este estudo demonstra pela primeira vez que a liraglutida melhora o endotelio sinusoidal hep?tico em modelos experimentais clinicamente relevantes de cirrose, o que leva a melhora no quadro fibr?tico e na hipertens?o portal e, portanto, pode ser v?lido no tratamento da doen?a hep?tica cr?nica avan?ada.

Esta dissertação analisa a percepção acerca do financiamento para os meios sem fins de lucro a partir da instituição da Lei 26.522, de Serviços de Comunicação Audiovisual (LSCA), na Argentina, conhecida no Brasil como Lei de Meios (Ley de Medios). Busca contribuir com o debate acerca das políticas públicas de comunicação na América Latina a partir da investigação sobre o processo de formulação e implantação de políticas públicas destinadas à sustentabilidade e à autonomia dos meios sem fins de lucro no processo de ocupação de um terço do espectro eletromagnético na Argentina. Amparado no processo teórico-metodológico da Hermenêutica de Profundidade (HP), desenvolvido por John B. Thompson (1999), fizemos análise de artigos, manifestos e entrevistas de especialistas e atores envolvidos no processo de implantação da LSCA e realizamos entrevista em profundidade com representantes de veículos sem fins de lucro na Argentina para apreender suas percepções acerca da Lei em implantação. Conclui-se que, por diversos fatores, cinco anos é um período ainda insuficiente para aplicação efetiva da Lei de Serviços de Comunicação Audiovisual, norma com tantas implicações, e verifica-se que a questão da sustentabilidade dos meios alternativos demanda, além do suporte econômico, preocupações com questões estéticas, técnicas e sociais. _______________________________________________________________________________________________ ABSTRACT
This dissertation addresses the funding for the no-profit means of communication from the enactment of Law 26.522 of Audiovisual Communication Services (LSCA), Argentina, popularly known in Brazil as Media Law (Ley de Medios). This text seeks to contribute to the debate about public communication policies in Latin America from the investigation into the formulation and implementation of public policies aimed at sustainability and autonomy of no-profit means in the process of occupation of one third of the electromagnetic spectrum in Argentina. Supported by the theoretical and methodological process of Depth Hermeneutics (HP) developed by John B. Thompson (1999), we have made the analysis of articles, manifestos and interviews of experts and stakeholders in the LSCA deployment process. Then we conducted in-depth interviews with representatives of non-profit vehicles in Argentina to seize their perceptions about the law being implemented. In conclusion, by several factors, Five years is a short time for the effective application of a law with so many implications, though check up significant progress in setting up an alternative means field. _______________________________________________________________________________________________ RESUMEN
Esta disertación aborda la percepción acerca de la financiación para los medios sin fines de lucro a partir de la instauración de la Ley 26.522 de Servicios de Comunicación Audiovisual (LSCA) en Argentina, popularmente conocida en Brasil como Lei de Meios (Ley de Medios). Busca contribuir con el debate acerca de las políticas públicas de comunicación en América Latina a partir de la investigación sobre el proceso de formulación e implantación de políticas públicas destinadas a la sostenibilidad y a la autonomía de los medios sin fines de lucro en el proceso de ocupación de un tercio del espectro electromagnético en Argentina amparado en el proceso teórico-metodológico de la Hermenéutica de Profundidad (HP) desarrollado por John B. Thompson (1999). Para la investigación fueron realizados análisis de artículos, manifiestos y entrevistas de especialistas y actores involucrados en el proceso de implementación de la LSCA al mismo tiempo que fueron realizadas profundas entrevistas con representantes de vehículos sin fines de lucro en Argentina para aprender su percepción acerca de la Ley implementada. Se concluye que, por diversos factores, cinco años es un corto período para la aplicación efectiva de la Ley de Servicios de Comunicación Audiovisual, normativa con tantas implicaciones, asimismo se verifica que el tema de la sostenibilidad de los medios alternativos demanda, además de un respaldo económico, una preocupación con temas estéticos, técnicos y sociales.

Повний текст джерелаMultiferroic YMnO3 (YMO) films have been grown by MOCVD on (100)-oriented Si, STO, LAOand LSAT substrates. The effect of the film thickness and the chemical composition on structuraland magnetic properties has been investigated. YMO can crystallize in two structure: hexagonal(h-YMO) and orthorhombic (o-YMO), generally considered as stable and metastable phases,respectively. Both phases, together with their amorphous precursor phase, are studied in this thesis.On one side, a selective growth of the amorphous, o-YMO or h-YMO phase is achieved on Sisubstrates through the deposition conditions. An extensive study of the optimal conditions hasbeen carried out. An irreversible phase transformation from amorphous to crystalline o-YMOphase takes place at an almost constant temperature (~ 700 °C) and in a short period of time (~min). The o-YMO phase thus obtained is stable at least up to 900 °C.On the other side, the o-YMO phase is epitaxially stabilized on perovskite type substrates (STO,LAO, LSAT). The films on STO and LSAT substrates present mainly the (010) orientation whilethose on LAO substrate are (101)-oriented. Secondary domain orientation are observe in particularon STO substrates: (010) in plane with 90° rotation. Strained films are observed for smallthicknesses. The magnetic measurements show a spin glass behavior for either o- or h-YMO phase,independently of the substrate

Повний текст джерелаEtt "network embedded cloud", även känt som ett "network enabled cloud" eller ett "carrier cloud", är en ny teknik trend som syftar till att tillhandahålla nätverkstjänster medan on-demand egenskapen av moln-paradigmet utnyttjas. Traditionella telekommunikationsapplikationer bygger ofta på en distributed service model och kan använda ett "network enabled cloud" som dess exekverande plattform. Dock kommer sådana inbäddade servrar av naturliga skäl vara geografiskt utspridda, varför de är beroende av topologisk och geografisk lokalisering. Detta ändrar på resurshanteringsproblemet jämfört med resurshantering i datacentrum. I de fall med ett network enabled cloud, utöver informationen om tillgängliga CPU, RAM och lagring, behöver resursfördelningsfunktionen information om nätverkets topologi och tillgänglig bandbredd på länkarna som förbinder de olika noderna i det distribuerade molnet. Detta examensarbete har utformat, tillämpat och utvärderat ett experiment-orienterad undersökning av användningen av open shortest path first med traffich engineering (OSPF-TE) för resurshantering i det network enabled cloud. I synnerhet utvidgades OSPF-TE till att förmedla virtualisering och behandla relaterad information till alla noder i nätverket. Detta examensarbete utvärderar genomförbarheten och lämpligheten av denna metod, dess flexibilitet och prestanda. Analysen visade att den föreslagna lösningen kan förse nödvändiga uppgifter till cloud management system genom att skicka ett datacenters resursinformation i form av ny opaque LSA (kallat Cloud LSA) med ett minimumintervall av 5 sekunder och maximal nätverksbelastning av 38,4 byte per sekund per inbäddade data center.

In this work, we focus on the task of clustering businesses in the state of Kansas based on the content of their websites and their business listing information. Our goal is to cluster the businesses and overcome the challenges facing current approaches such as: data noise, low number of clustered businesses, and lack of evaluation approach. We propose an LSA-based approach to analyze the businesses’ data and cluster those businesses by using Bisecting K-Means algorithm. In this approach, we analyze the businesses’ data by using LSA and produce businesses’ representations in a reduced space. We then use the businesses’ representations to cluster the businesses by applying the Bisecting K-Means algorithm. We also apply an existing LDA-based approach to cluster the businesses and compare the results with our proposed LSA-based approach at the end. In this work, we evaluate the results by using a human-expert-based evaluation procedure. At the end, we visualize the clusters produced in this work by using Google Earth and Tableau. According to our evaluation procedure, the LDA-based approach performed slightly bet- ter then the LSA-based approach. However, with the LDA-based approach, there were some limitations which are: low number of clustered businesses, and not being able to produce a hierarchical tree for the clusters. With the LSA-based approach, we were able to cluster all the businesses and produce a hierarchical tree for the clusters.

Повний текст джерелаThe decision-making process, in different management environments, faces a moment of change in the organizational context. In this sense, Business Analytics can be seen as an area that leverages the value of data, containing important tools for the decision-making process. However, the presence of data in different formats poses a challenge. In this context of variability, text data has attracted the attention of organizations, as thousands of people express themselves daily in this format in many applications and tools available. Although several techniques have been developed by the computer science community, there is ample scope to improve the organizational use of such text data, especially when it comes to decision-making support. However, despite the importance and availability of textual data to support decisions, its use is not common because of the analysis and interpretation challenge that the volume and the unstructured format of text data presents. Thus, the aim of this dissertation is to develop and evaluate a framework to contribute with the expansion and development of text analytics in decision-making processes, based on several natural language processing (NLP) techniques. The results presents the validity of the framework, using as a demonstration of its applicability the tourism sector through the TripAdvisor platform, as well as the internal validation of performance and the acceptance by managers.
