Full textAbstract:
Self-regulation refers to our individual capacities to regulate our behaviours, emotions, and thoughts, with these skills developing rapidly across early childhood. This thesis examined sleep, emotional, and cognitive regulation development, and related parental influences, for children participating in the Longitudinal Study of Australian Children. Important longitudinal associations among children's self-regulation, maternal mental health, parenting, and later behaviour problems for children were also investigated. A unique contribution of this research was a prevalence estimate of early childhood self-regulation problems in Australian children that was documented for the first time.

Full textAbstract:
This research utilised data from The Longitudinal Study of Australian Children and explored continuity and change in parental engagement in home learning activities with young children. The findings indicated a decrease over time in parental engagement with children, from age to 2-3 years to 6-7 years. Rate of decrease impacted negatively on learning outcomes for language and literacy, and mathematical thinking, in the early years of school, when children were aged 6-7 years. Shared reading with children and interactions around everyday home activities and play, in which children and parents participate together, impact on children's later development.

Full textAbstract:
Between April 27th 1995 and April 26th 2005, patients with external cause lesions seen at the pediatric orthopedic outpatient clinic of the Maria Amelia Lins Hospital were studied. The objective was to identify the characteristics, patients profile through the variables: age, gender, trauma mechanism, side, topographic localization, associated injuries and compare the epidemiological results with the literature findings. The inclusion criterias were: have a external cause lesion, find the medical records with the appropriate research informations and have open physes. In the above mentioned period 2472 patients were identified, of which 1199 fitted the inclusion criterias. Patients identification and lesion characteristics were taken from the medical records. Age was count in absolute years. Mechanism of trauma were grouped in falls, traffic accidents, direct trauma, others and without information. Thetypes of lesions were divided in amputation, fractures, epiphysiolises, luxations, head trauma, contusions, internal organs injuries, face injuries, and others. Fractures, fracture-luxation, epiphysiolises and luxations were, also, classified as open or closed. Topographic localizationswere classified in relation to bony segments. Patients were grouped in general population, isolated injuries, multiple lesions that had more then one segment and/or of other organs involved. The orthopedic injuries that required more secondary attention were described asprincipal. From the general sample, 838 (68.9%) patients had isolated injuries, 361 (30.1%) patients had 884 multiple lesions. Mean age was 7.6±3.4 years. Masculine gender and the left side predominated. In the isolated injuries the upper limbs were more affected while lowerlimbs were more affected in multiple lesions. The most common trauma mechanisms in general and isolated groups, were falls (39.0% e 44,3%) and traffic accidents in multiple injuries (42,7%). Fracture was the most frequent type of lesion was (73,0% - general sample, 85,3% - isolated injuries and 61,1% - in multiple injuries). Elbow fractures (24%) were the most common topographic localization among the isolated injuries, while leg fractures (12,9%) were the most common among the multiple injuries. One associated injury was seen in 67.% of the multiple lesions 24.3% had two, 5.3% had three and 3.3% had four. Mainly the associationamong elbow fractures and forearm fractures with 25 cases. In conclusion, the descriptive characteristics were the same as the literature. The isolated injury patients´ profile is: boys, inschool age, victims of fall, with upper limb long bone closed fractures. The multiple injury patients´ profile is: boys, at school age, victims of traffic accidents, with lower limb long bone fractures associated with other injuries. Protocols development and introduction are of essential for bias exclusion and comparison in this type of study.No 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.

Neue Methoden zur Verkehrsdatenerfassung wie die Fahrzeug-Infrastruktur-Kommunikation, der Floating Car-Ansatz und die Videodetektion eröffnen die Möglichkeit, neue Verfahren zur verkehrsabhängigen Lichtsignalanlagensteuerung zu realisieren. In dem Beitrag wird ein Verfahren beschrieben, das aus diesen Quellen Daten in Form von Fahrzeugverlustzeiten direkt zur Steuerung eines Einzelknotens verwendet. Die robuste Ausgestaltung des Verfahrens sorgt dabei dafür, dass auch mit einer lückenhaften Datenlage, wie z. B. aufgrund geringer Ausstattungsraten kommunikationsfähiger Fahrzeuge, angemessen umgegangen werden kann. Mit Hilfe einer mikroskopischen Simulationsstudie wird nachgewiesen, dass das neue Verfahren bei der Qualität des Verkehrsablaufs das gleiche Niveau wie eine traditionelle Zeitlückensteuerung erreicht oder dieses unter bestimmten Bedingungen sogar übersteigt. Mit abnehmender Ausstattungsrate ergibt sich dabei allerdings ein Qualitätsverlust, der ebenfalls mit Hilfe der mikroskopischen Simulation quantifiziert wird und wichtige Erkenntnisse für einen möglichen Praxistest liefertState-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.

Full textAbstract:
Abstract The commercial long-term evolution (LTE) networks of today offer fast and regionally wide access to the Internet and to the commercial applications and services at a reasonable price. At the same time, public safety (PS) users are still communicating with old-fashioned, second-generation voice and data services. Recently, the commercial LTE networks have been standardized to offer capabilities to mission-critical users. However, the commercial networks do not yet fully support the coverage requirements of the PS users. Moreover, the commercial infrastructure might be out of order in critical scenarios where PS actors are needed. Thus, the PS users require, for example, rapidly deployed LTE networks to support their own communication. This thesis studies the PS use of commercial operators' LTE networks and rapidly deployed closed LTE networks. The key tasks are to find out how to connect users seamlessly together between the different networks as well as finding out how the frequency planning is implemented. This thesis provides practical design solutions to guarantee network interoperability by connecting the networks as well as radio spectrum utilization solutions by licensed shared access (LSA). While the concept of LSA has been well developed, it has not been thoroughly investigated from the point of view of the PS actors, who have special requirements and should benefit from the concept. Herein, the alternatives for spectrum sharing between PS and commercial systems are discussed. Moreover, the thesis develops a specific LSA spectrum sharing system for the PS actors deploying their own network in scenarios where the commercial networks are insufficient. The solution is a robust LSA-based spectrum sharing mechanism. Note that PS actors also need to be able to utilize the spectrum when the LSA system is not available and when the commercial system has failed. Thus, this thesis proceeds on developing sensing methods for complementing LSA, where the sensing methods guarantee spectrum information for a rapidly deployed PS network. It is shown how PS actors can utilize available spectrum with a secondary spectrum licence. This is a good alternative to reserving the spectrum completely. The work assembles missing pieces of existing methods to ensure the functionality of the commercial and of the supporting rapidly deployed networks, both in terms of spectrum usage and application servicesTiivistelmä 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

Full textAbstract:
This thesis gives a description and a syntactic analysis for coordination and gapping in conjunction in Catalan Sign Language (LSC) within the framework of Generative Grammar and Minimalism. Regarding coordination, Coordination Phrase (CoP) is proposed as the category for conjunctive, disjunctive and adversative coordination, assuming that the conjuncts are specifiers and complements of CoP in a right-branching coordination structure. The specific derivation for each types of coordination is then applied.
As for gapping in conjunction, in LSC it shows similarities with VP-ellipsis, especially because it can appear also in subordination. Moreover, the availability of only distributed scope negation (¬A&¬B) and the presence of contrastive topic and contrastive focus require a large coordination structure, that is, CP coordination. In order to derive gapping, I propose movement of the arguments to TopP and FocP followed by the deletion of TP at PF, with [E] feature in the head of FocP.Aquesta 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.

Aquesta tesi presenta la primera descripció de les construccions relatives (CR) restrictives en llengua de signes catalana (LSC). A més, inclou una proposta d’anàlisi en el marc de la gramàtica generativa transformacional informada tipològicament.
Respecte a la tipologia sintàctica de les CR, aportem proves que mostren que aquestes construccions, en LSC, són estructures circumnominals, és a dir, amb el pivot (o antecedent) dins de l’oració relativa (OR). Això contrasta amb les CR més comunes a les llengües indoeuropees, les adnominals, en què el pivot apareix fora de l’OR. Les CR circumnominals de la LSC, d’acord amb el que diu la tipologia, presenten un determinant que nominalitza l’estructura.
Les CR circumnominals de la LSC no apareixen mai a la seva posició bàsica dins de l’oració matriu sinó que han d’aparèixer o bé avantposades o bé posposades. Aquesta mateixa distribució s’observa a les CR circumnominals d’altres llengües de signes, com ara la llengua de signes italiana (LIS).
L’anàlisi que presentem és essencialment la d’elevació, en la línia de Kayne (1994), encara que hi introduïm algunes modificacions per tal de donar compte de les dades de la LSC. Aquesta anàlisi, en principi, seria d’aplicació a les CR circumnominals en general, es tracti de llengües orals o signades.
Aquest treball representa, doncs, una contribució tant a la tipologia com a la lingüística teòrica.This 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.

This thesis provides a morphosyntactic description of polar questions and

Polar questions in LSC are obligatorily marked with a specific combination
of non-manual marking features and optionally marked with a question
particle. Given that, at least, the most prominent feature, eyebrow position,
does not remain constant, LSC displays different combinations of
non-manuals to mark this structure. Empirical evidence supports an analysis
in which each combination of non-manuals conveys a different bias
and a novel feature-based description system explains and predicts those.
Therefore, each combination of non-manuals, as well as the appearance of
the question particle, is shown to not only mark sentence type but also to
encode specific pragmatic meanings.Aquesta tesi ofereix una descripció morfosintàctica de les preguntes polars i una anàlisi pragmàtica de les preguntes esbiaixades en llengua de signes` catalana (LSC). Les preguntes polars en LSC es marquen obligatòriament amb una combinació específica de trets no manuals i, opcionalment, amb una partícula interrogativa. Ates que, si més no, el tret més destacat, la posició de les celles, no roman constant, l’LSC mostra diferents combinacions de no manuals per marcar aquesta estructura. L’evidencia científica dona suport a una anàlisi en què cadascuna de les combinacions de no manuals codifica un biaix diferent; un nou sistema de descripció basat en trets explica i prediu aquest comportament. Per tant, cada combinació de no manuals, així com l’aparició de la partícula interrogativa, es realitza no nomes per marcar el tipus d’oració, sinó també per codificar significats pragmàtics.
Esta tesis proporciona una descripción morfosintáctica de las preguntas polares y un analisis pragmático de las preguntas sesgadas en lengua de signos catalana (LSC). Las preguntas polares se marcan obligatoriamente con una combinacion específica de rasgos no manuales y opcionalmente con una partícula interrogativa. Dado que, al menos, el rasgo mas destacado, la posición de las cejas, no permanece constante, la LSC muestra diferentes combinaciones de no manuales para marcar esta estructura. La evidencia empírica sostiene un analisis en el que cada combinación de no manuales transmite un sesgo diferente; un novedoso sistema de descripcion basado en rasgos explica y predice esta conducta. Por ende, cada combinación de no manuales, así como la aparición de la partícula interrogativa, se realiza no solo para marcar el tipo de oración, sino también para codificar significados pragmáticos.

This thesis provides a description and a pragmatic analysis of the expression and interpretation of focus and contrast in Catalan Sign Language (LSC). I argue that LSC data provides empirical evidence that contrast is an independent notion in Information Structure that can overlap with topics and foci, and that involves different types, which are built compositionally. All types of contrast share a basic meaning (semantic parallelism), which is essential for an element to be contrastive, and which is expressed through a specific combination of non-manual markers (NMMs). Additional prosodic NMMs are used to trigger more complex meanings, like exhaustivity or counterexpectation. Moreover, a first description of focus particles and clefts in LSC is provided, together with a pragmatic analysis of exhaustivity and non-truth conditional meaning (presuppositions and implicatures) in these constructions.Aquesta tesi proporciona una descripció i una anàlisi pragmàtica de l’expressió i la interpretació del focus i el contrast en llengua de signes catalana (LSC). Defenso que l’LSC aporta proves empíriques que el contrast és una noció independent en el camp de l’estructura informativa que se solapa amb el tòpic i els focus de l’oració i que es pot dividir en subtipus que es conformen de manera composicional. Tots els tipus de contrast comparteixen un significat bàsic (paral·lelisme semàntic), que és imprescindible perquè un element sigui contrastiu i que s’expressa a través d’una combinació específica de marcadors no manuals (MNM). MNM addicionals són emprats per expressar significats més complexos, com ara l’exhaustivitat i la contraexpectació. A més, s’ofereix una primera descripció de les partícules focals i les oracions clivellades en LSC, i una anàlisi pragmàtica de l’exhaustivitat i el significat no veritatiu-condicional (implicatures i pressuposicions) que es deriva d’aquestes construccions.

Languages use different resources to specify the numerosity of the
referents and to denote the speech act participants. This thesis describes
the morphophonological strategies used in Catalan Sign Language
(LSC) personal pronouns to encode these distinctions. In a nutshell,
I argue that the expression of person and number is achieved by
using two interrelated strategies: person is expressed through spatial
features (locations in the signing space which are defined in relation
to the signer’s body), number is grammatically marked by the path
specifications of the sign (movements connecting spatial locations).
Combining these two operations results in the formal marking of three
person distinctions (with a further contrast between exclusive, minimal
inclusive and augmented inclusive in the first person) and four number
values (singular, dual, paucal and plural).Les llengües utilitzen diferents recursos per a expressar el nombre dels referents i designar als participants en els actes de parla. 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).

Aquesta tesi se centra en la identificació i descripció de la categoria verb (V) en la llengua de signes catalana (LSC). Hem emmarcat la nostra recerca en el marc teòric de Borer (bàsicament 2005a i 2005b), el qual ens ha permès analitzar la LSC des d’una perspectiva diferent a d’altres treballs descriptius.
Al llarg d’aquest treball descrivim els functors lèxics (FL) i els functors funcionals (FF) que hem pogut identificar per a la categoria V en el corpus objecte del nostre estudi en LSC. Seguint diverses investigacions referides a altres llengües de signes, iniciem el nostre treball amb un estudi d’un conjunt de parells nom-verb de la LSC i n’identifiquem les diferències morfofonològiques. En aquest nivell de descripció morfofonològica distingim dos FL que fan que l’arrel lèxica inserida en el nucli del SV esdevingui i s’identifiqui com a equivalent a V, cosa que permet que se li assigni una estructura eventiva. Posteriorment, analitzem els FF (This 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.

Full textAbstract:
Over the last ten years, the demand for data has been increasing exponentially. To meet this demand, there are three ways to proceed: increasing the number of antennas, enhancing spectrum efficiency, enlarging bandwidths. This paper is focused on the last option, enlarging the bandwidth, and more precisely on the reuse or secondary use of frequencies through Licensed Shared Access and TV white spaces. This work aims at determining the potential development of these two new regulatory regimes and the potential impact on the telecom ecosystem and business.There is a common understanding of TVWS and regulators are implementing similar frameworks. The industry and regulators have launched plenty of trials and developed many standards. There are even some examples of commercial releases. However, the amount of channels available for TVWS activities is still uncertain since regulators have not stated their positions on the balancing between TVWS and digital dividend (refarming). Their decision will influence the market size and consequently the market take-up.Similarly to TVWS, national and international coherent regulatory frameworks are being developed around LSA. There is also a common view on uses among actors. Indoor coverage is one of the most mentioned uses. This will enhance the actors’ confidence in LSA, and might consequently increase investment. However, standardization is needed to bring the necessary economies of scale. The incumbents’ willingness to share their spectrums and the fees level are still unclear. These last parameters will have large impact on LSA take-up.The second part of the thesis tries to determine what ecosystems might develop. With TVWS, there are no licence fees or coverage requirements included in licence, which lowers the entrance barriers. This paper presents strategies where other players than MNOs provide connectivity. These strategies, which were built through group exercises done by Telecom workers, bring opportunities to these new connectivity providers and also values for its potential clients. Moreover, these new connectivity provider strategies possess real strengths and only limited weaknesses. However, the MNOs’ reluctance to support this new ecosystem is the most dangerous threat to its development.To a slightly lesser extent, LSA also lowers the entrance barriers into the connectivity-providing business. This is a game-changer for indoor coverage since LSA might enable the development of scenarios and ecosystems which were previously considered as hypothetical. Thus, scenario where a Managed Service Providers or a Network Equipment Providers offers connectivity (without MNOs) to a premise or a MVNO has the potential to take up. This strategy is valuable for connectivity providers and their clients. Here, financing this strategy is also a challenge, but the most important risk might arise from the MNOs’ pressures on the ecosystem’s actors to prevent this strategy from developing.

Mit der wachsenden Popularität von GitHub, dem größten Online-Anbieter von Programm-Quellcode und der größten Kollaborationsplattform der Welt, hat es sich zu einer Big-Data-Ressource entfaltet, die eine Vielfalt von Open-Source-Repositorien (OSR) anbietet. Gegenwärtig gibt es auf GitHub mehr als eine Million Organisationen, darunter solche wie Google, Facebook, Twitter, Yahoo, CRAN, RStudio, D3, Plotly und viele mehr. GitHub verfügt über eine umfassende REST API, die es Forschern ermöglicht, wertvolle Informationen über die Entwicklungszyklen von Software und Forschung abzurufen. Unsere Arbeit verfolgt zwei Hauptziele: (I) ein automatisches OSR-Kategorisierungssystem für Data Science Teams und Softwareentwickler zu ermöglichen, das Entdeckbarkeit, Technologietransfer und Koexistenz fördert. (II) Visuelle Daten-Exploration und thematisch strukturierte Navigation innerhalb von GitHub-Organisationen für reproduzierbare Kooperationsforschung und Web-Applikationen zu etablieren. Um Mehrwert aus Big Data zu generieren, ist die Speicherung und Verarbeitung der Datensemantik und Metadaten essenziell. Ferner ist die Wahl eines geeigneten Text Mining (TM) Modells von Bedeutung. Die dynamische Kalibrierung der Metadaten-Konfigurationen, TM Modelle (VSM, GVSM, LSA), Clustering-Methoden und Clustering-Qualitätsindizes wird als "Smart Clusterization" abgekürzt. Data-Driven Documents (D3) und Three.js (3D) sind JavaScript-Bibliotheken, um dynamische, interaktive Datenvisualisierung zu erzeugen. Beide Techniken erlauben Visuelles Data Mining (VDM) in Webbrowsern, und werden als D3-3D abgekürzt. Latent Semantic Analysis (LSA) misst semantische Information durch Kontingenzanalyse des Textkorpus. Ihre Eigenschaften und Anwendbarkeit für Big-Data-Analytik werden demonstriert. "Smart clusterization", kombiniert mit den dynamischen VDM-Möglichkeiten von D3-3D, wird unter dem Begriff "Dynamic Clustering and Visualization of Smart Data via D3-3D-LSA" zusammengefasst.With 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".

Full textAbstract:
Dense ceramic oxygen separation membranes can pass oxygen perm-selectively at elevated temperature and have potential for improving the performance and reducing the cost of several industrial processes: such as the conversion of natural gas to syngas, or to separate oxygen from air for oxy-fuel combustion in electricity generation (to reduce NOx emissions and facilitate CO2 sequestration). These pressure-driven solid state membranes are based on fast oxygen-ion conducting ceramics, but also need a compensating flow of electrons. Dual-phase composites are attractive since they provide an extra degree of freedom, compared with single phase membranes, for optimising the overall membrane performance. In this study, composites containing gadolinia doped ceria (CGO, Ce0.9Gd0.1O2- ) and either strontium-doped lanthanum cobaltite (LSC, La0.9Sr0.1CoO3- or La0.6Sr0.4CoO3- ) or silver (Ag) were investigated for possible application as oxygen separation membranes in oxy-fuel combustion system. These should combine the high oxygen ion conductivity of CGO with the high electronic conductivity and fast oxygen surface exchange of LSC or silver. Dense mixed-conducting composite materials of LSC/CGO (prepared by powder mixing and sintering) and Ag/CGO composites (prepared by silver plus copper oxide infiltration method) showed high relative density (above 95%), low background gas leakage and also good electrical conduction. The percolation threshold of the electronic conducting component was determined to be approximately 20 vol.% for both LSC compositions and 14 vol.% for Ag. Isotopic exchange and depth profiling by secondary ion mass spectrometry was used to investigated the oxygen tracer diffusion (D*) and surface exchange coefficient (k*) of the composites. Composites just above the electronic percolation threshold exhibited high solid state oxygen diffusivity, fast surface exchange activity moderate thermal expansion and sufficient mechanical strength thus combining the benefits of their constituent materials. The preliminary work on oxygen permeation measurement showed that the reasonable magnitude of oxygen fluxes is possible to be achieved. This indicates that the composites of LSC/CGO and Ag/CGO are promising for further development as passive oxygen separation membranes.

This thesis will examine the potential of the two competing designs for the Littoral Combat Ship (LCS), with regard to potential deployment of this vessel type by the Turkish Navy. The first design is by Lockheed Martin and has been designated the USS Freedom as the U.S. Navyâ s first LCS. The second design is by General Dynamics. This thesis will focus on the LCS usage concepts in Naval Capability Pillars and Information Operations. As a transformation platform, the LCS will be critical in implementing new operational concepts and in providing a focused, littoral mission platform for joint forces. Its superior speed and maneuverability; low radar, infrared, and acoustic signatures; and ability to lay distributed sensor fields are all fundamental to mission success. It will also carry a â squadronâ of unmanned vehicles (air, surface, and undersea) that will considerably extend its sensor and weapon coverage and provide substantial Anti-Submarine Warfare (ASW) capabilities. This thesis will also discuss present and future platforms and their concepts of operation in Turkish littoral waters (Aegean Sea, Black Sea, and Mediterranean Sea).

The purpose of this work was to calculate and to test different aircraft components according to the CS-LSA (Light Sport Aircraft) airworthiness for Shark s.r.o. Shark was designed to fit into European ultralight category and it was approved according to the UL-2 Czech Republic requirement of Light Aircraft Association and LTF-UL German requirement for “Sport Flying Vehicles”. In the design phase were considered also the ASTM standards for Light Sport Aircraft (LSA) valid in USA and accepted by European regulation CS-LSA. The maximum take-off weight will be increased from 472.5 kg up to 600 kg. Most of the tests needed for proof and approval were performed for calculated load according to ASTM standards, but some only up to limited load corresponding to maximum take-off weight equal to 472.5 kg. The goal of the project was to go through the Shark s.r.o documents and to check the compliancy with CS-LSA regulation. The center of gravity position was calculated starting from the prototype and new flight envelope was designed for calculation of the limit load afterwards. New tests were realized on the flaps, fixing points of the ballistic rescue system and on the landing gear. The tests were performed in Shark aero facility in Senica (Slovakia) under the supervision of Eng. Vladimír Pekár. The data collected during multiple tests were used for preliminary design of Mako - new aerobatic aircraft for pilot training.

Full textAbstract:
This thesis concerns the use of sign space in Catalan Sign Language (LSC) at the discourse level. I argue that non-descriptive locations are established in the three spatial planes and I describe the grammatical features contained within them. Spatial locations are morphophonologically marked with an abstract point in space which does not have a specific direction and which is categorically interpreted in the linguistic system. In LSC, the frontal plane is grammatically relevant for specificity marking: lower spatial locations correlate with specificity, whereas upper locations correlate with non-specificity. Moreover, the incorporation of discourse structure into the analysis shows that the establishment of lower spatial locations also denotes discourse prominence. Hence, spatial locations are integrated into the grammar of LSC and they are analysed here with respect to the role they play in the denotation of specificity and discourse structure. The analysis is framed under the formalisation of Discourse Representation Theory, on the basis of a small-scale LSC corpus.Aquesta 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.

The significant increase in mobile data traffc has put a considerable load on the wireless mobile networks. In the current highly competitive market, Mobile Network Operators (MNOs) have to strive to provide additional capacityof their network, by also considering the cost factor to make their business sustainable. Along with advances in spectrum-efficient technologies, small cells deployment have provided cost-efficient methods to provide additional capacity for indoor and outdoor subscribers. The gain of better spectrum utilization and opportunistic spectrum access have motivated the deployment of wireless networks utilizing below 6GHz spectrum, where there are opportunities for mobile networks to access the spectrum by co-existing with incumbent users and technologies. Two emerging complementary spectrum authorizations have attracted industry and academia, Licensed Shared Access (LSA) and License Assisted Access(LAA). In this thesis, the techno-economic aspects of operating under individual authorization (LSA) and general authorization (LAA) regimes are investigated and compared. The dynamics of operating under unlicensed spectrum are represented considering the scenario of two MNOs co-existing following the regulatory requirements. The results show that choosing the appropriate channel selection mechanism is of high importance when operating under the unlicensed regime (LAA). The results indicate that LAA can be an alternative for cost-efficient deployment method in some scenarios, for example when there is a low or moderate availability of LSA bandwidth. For the future work, we suggest an optimized user association to the small cells to provide a better load balancing mechanism.Den 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.

Masivní vývoj Internetu vedl ke zvýšeným požadavkům na spolehlivou síťovou infrastrukturu. Efektivita komunikace v síti závisí na schopnosti směrovačů určit nejlepší cestu pro odesílání a přeposílání paketů ke koncovému zařízení. Jelikož OSPF v současné době představuje jeden z nejpoužívanějších směrovacích protokolů, jakýkoli přínos, který by pomohl udržet krok s rychle se měnícím prostředí Internetu, je velmi vítán. Významným omezením OSPF protokolu je, mimo jiné, absence informovanosti algoritmu pro výpočet metriky o aktuálním vytížení linky. Tato vlastnost představuje tzv. slabé místo, což má negativní vliv na výkonnost sítě. Z tohoto důvodu byla navržena nová metoda založená na dynamické adaptaci měnících se síťových podmínek a alternativní strategii OSPF metrik. Navržená metoda řeší problém neinformovanosti OSPF metriky o síťovém provozu a nevhodně vytížených linek, které snižují výkonnost sítě. Práce rovněž přináší praktickou realizaci, kdy vlastnosti nové metody jsou testovány a ověřeny spuštěním testů algoritmu v reálných zařízeních.

Full textAbstract:
The research investigated whether a Latent Semantic Analysis (LSA)-based approach to image retrieval can map pixel intensity into a smaller concept space with good accuracy and reasonable computational cost. From a large set of computed tomography (CT) images, a retrieval query found all images for a particular patient based on semantic similarity. The effectiveness of the LSA retrieval was evaluated based on precision, recall, and F-score.
This work extended the application of LSA to high-resolution CT radiology images. The images were chosen for their unique characteristics and their importance in medicine. Because CT images are intensity-only, they carry less information than color images. They typically have greater noise, higher intensity, greater contrast, and fewer colors than a raw RGB image. The study targeted level of intensity for image features extraction.
The focus of this work was a formal evaluation of the LSA method in the context of large number of high-resolution radiology images. The study reported on preprocessing and retrieval time and discussed how reduction of the feature set size affected the results. LSA is an information retrieval technique that is based on the vector-space model. It works by reducing the dimensionality of the vector space, bringing similar terms and documents closer together. Matlab software was used to report on retrieval and preprocessing time.
In determining the minimum size of concept space, it was found that the best combination of precision, recall, and F-score was achieved with 250 concepts (k = 250). This research reported precision of 100% on 100% of the queries and recall close to 90% on 100% of the queries with k=250. Selecting a higher number of concepts did not improve recall and resulted in significantly increased computational cost.

O estudo da responsabilidade civil dos administradores de companhias abertas na doutrina nacional trata usualmente dos deveres fiduciários, do ato regular de gestão e da teoria ultra vires, da culpa ou dolo do administrador, das ações ut universi e ut singuli e da solidariedade entre a responsabilidade do administrador e a da companhia. Poucos abordam as causas extintivas dessa responsabilidade, e raro são os que tratam da hipótese de exclusão de responsabilidade do artigo 159, § 6º, da Lei nº 6.404/76. Como a disciplina dos deveres fiduciários prevista na lei societária brasileira tem forte influência do Direito norte-americano, buscou-se na legislação, doutrina e jurisprudência daquele país os fundamentos necessários à melhor interpretação e aplicação da regra de exclusão e, em especial, na business judgment rule, doutrina que protege os administradores contra responsabilização por prejuízos à companhia decorrentes de decisões por eles adotadas, proteção esta também conferida pela hipótese do artigo 159, § 6º, da Lei nº 6.404/76, ao administrador leal e de boa-fé.The 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.

Déterminant d’un vieillissement actif et en santé, la mobilité permet aux aînés de maintenir et de développer des liens sociaux significatifs, et de demeurer intégrés dans leur communauté. Malgré ces bienfaits, les interventions offertes aux aînés visant à favoriser leurs déplacements restent rares et discontinues. Un accompagnement-citoyen personnalisé d’intégration communautaire (APIC) pourrait favoriser les déplacements et améliorer la perception des lieux des aînés en perte d’autonomie. Cette étude visait à : 1) vérifier les effets de l’APIC sur les déplacements et l’espace perçu des aînés en perte d’autonomie et 2) identifier les facilitateurs et les obstacles à l’utilisation de l’espace dans l’APIC. Un devis mixte incluant un dispositif pré-expérimental a été utilisé auprès de 16 participants (11 femmes) âgés entre 66 et 91 ans. Les déplacements ont été mesurés à l’aide du Life Space Assessment. Un entretien individuel semi-structuré d’environ 30 minutes a été réalisé 2 à 4 semaines après la fin de l’intervention. À la suite de l’APIC, les déplacements des participants se sont améliorés (p < 0,01). Selon les participants âgés, l’APIC constitue un facilitateur important qui a permis de découvrir des lieux de participation et d’améliorer leur capacité à se déplacer seul. L’APIC est une intervention prometteuse qui permet d’améliorer les déplacements et l’utilisation de l’espace d’aînés en perte d’autonomie.

This study aims to investigate different orbit determination algorithms for the first Turkish remote sensing satellite, BiLSAT-1. The micro-satellite carries an onboard GPS receiver. Pseudorange measurements simulated from the position and velocity data supplied by TÜBiTAK-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.

Full textAbstract:
Physical education (PE) for pupils with special educational needs (SEN) is an important contemporary issue for primary teachers and other practitioners. In particular, how they are to include pupils with SEN in their classroom activity is a processing concern. This study is concerned essentially with how policy influences the ability of teachers to deal with SEN' pupils in PE. It explores the relationships between education policy on SEN and its implementation within PE when SEN pupils are placed in mainstream school settings. The main aims of this thesis are to explore how 'equality' and 'inclusion' are expressed in legislation, for example the National Curriculum in England and the Grade 1- 9 Curriculum Guidelines in Taiwan, and how teachers, local education authority (LEA) Advisors, pupils with physical disability and their parents interpret policy and engage in practice for SEN. The findings of the study are intended to provide guidance on education policy needed to promote 'inclusion' and connect SEN policy and its implementation within PE. This thesis develops and utilizes a theoretical model to illustrate the 'flow' of policy from government to schools. This framework has followed Bernstein's (1990) assertion that knowledge is produced and reproduced at different sites of practice and that 'discourses' are recontextualized in each. Qualitative research methods were used to explore these relationships. The research fields were located in the Midlands in England and in the North of Taiwan and investigate LEAs and primary schools. The research employed interviews, documentary analysis and observation to explore policy and its implementation for SEN pupils from not only a 'macro' but also a 'micro' perspective. Accordingly, this thesis has explored the relationships between teachers, the learning support assistants (LSA), pupils with physical disability and their activities in PE classrooms in order to throw light on processes of inclusion within PE and the difficulties associated with policy implementation for pupils with physical disability. The findings suggest that the implementation of SEN policy within PE was driven by ideals of inclusion and attempted to achieve equality. However, SEN policy and its implementation was rendered difficult by the production and reproduction of particular understandings of inclusion, and inadequate provision (training and resource) for teachers to deal with SEN pupils in PE. Compared with teachers in England, PE teachers in Taiwan seemed to be more 'able' to include SEN pupils in PE as they were less regulated by National Curriculum texts.

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

Full textAbstract:
This thesis examines variation within the microlith industries of the Later Stone Age (LSA) of Northwest Africa, around the time of the Last Glacial Maximum (LGM) until the onset of the Holocene, between ∼25 - 11.5 ka. The traditionally held view is that whilst there is variation amongst the lithic assemblages, this can all be accommodated by a single definable industry, known as the Iberomaurusian. This thesis indicates an alternative scenario. Based on the typo-technological analysis of 16,689 lithic artefacts recovered from recent excavations at the site of Grotte des Pigeons (Taforalt, Morocco) and the re-analysis of published data using the multivariate statistical approach of correspondence analysis (CA), this thesis shows that there was much greater variation than previously proposed within the Pleistocene LSA. This thesis indicates that the LSA industries can be sub-divided into four chronologically distinct variants, an Initial LSA time-coincident with the first appearance of microlithic technology from ∼25 ka and lasting up until Heinrich event 2, a succeeding Early LSA at ∼22 ka that continued until Heinrich event 1, a Middle LSA marking a shift in technologies around this event at ∼16 ka, and an Upper LSA occurring with the climatic amelioration of the Bølling-Allørod at ∼14.5 ka. The proposed chronological model provides a new framework for categorising variation within the LSA, which is a necessary pre-requisite for potential future research addressing wider anthropological and archaeological issues, such as reasons for shifts in subsistence and settlement.

Couches minces multiferroiques d’YMnO3 (YMO) films ont été synthétisée par MOCVD sur desubstrats de Si, STO, LAO et LSAT orientées (100). L'effet de l'épaisseur des couches et de lacomposition chimique sur les propriétés structurales et magnétiques a été étudié. YMO peutcristalliser dans deux structure : hexagonale (h-YMO) et orthorhombique (o-YMO), généralementconsidérée comme les phases stables et métastables, respectivement. Les deux phases, ainsi queleur phase précurseur amorphe sont étudiées dans cette thèse. D'un côté, une croissance sélectivede la phase amorphe, h-YMO ou o-YMO est réalisé sur des substrats de Si en ajustant lesconditions de dépôt. Une étude approfondie des conditions optimales a été réalisée. Unetransformation de phase irréversible de l'état amorphe à la phase cristalline o-YMO a lieu à unetempérature à peu près constante (~ 700 ° C) et dans un court période de temps (min ~). La phaseo-YMO ainsi obtenue est stable au moins jusqu'à 900 ° C.De l'autre côté, la phase o-YMO est stabilisé par épitaxie sur des substrats de type perovskite (STO,LAO, LSAT). Les films sur STO et LSAT présentent principalement l’orientation (010) tandis queceux sur les substrats de LAO sont orientées (101). Une orientation secondaire de domaines estobservée en particulier sur des substrats de STO: rotation de 90 ° dans le plan du domaine (010).A des faibles épaisseurs les couches sont contraintes. Les mesures magnétiques montrent uncomportement de verre de spin pour chacune de phase o- ou h-YMO, indépendamment du substratMultiferroic 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

Dealing with big data, this thesis presents a novel and effective approach of scalable document clustering via ranking. The proposed clustering methods address the high-dimensionality problem in clustering analysis by introducing effective and computationally efficient cluster representations. The clustering via ranking approach is applicable to semi-supervised and unsupervised clustering problems. The proposed methods are applicable to static data as well as streaming data. The methods have been successfully tested with big social media data providing interesting insight.

Full textAbstract:
The notions of "network embedded cloud", also known as a "network enabled cloud" or a "carrier cloud", is an emerging technology trend aiming to integrate network services while exploiting the on-demand nature of the cloud paradigm. A network embedded cloud is a distributed cloud environment where data centers are distributed at the edge of the operator's network. Distributing data centers or computing resources across the network introduces topological and geographical locality dependency. In the case of a network enabled cloud, in addition to the information regarding available processing, memory, and storage capacity, resource management requires information regarding the network's topology and available bandwidth on the links connecting the different nodes of the distributed cloud. This thesis project designed, implemented, and evaluated the use of open shortest path first with traffic engineering (OSPF-TE) for propagating the resource status in a network enabled cloud. The information carried over OSPF-TE are used for network-aware scheduling of virtual machines. In particular, OSPF-TE was extended to convey virtualization and processing related information to all the nodes in the network enabled cloud. Modeling, emulation, and analysis shows the proposed solution can provide the required data to a cloud management system by sending a data center's resources information in the form of new opaque link-state advertisement with a minimum interval of 5 seconds. In this case, each embedded data centers injects a maximum 38.4 bytes per second of additional traffic in to the network.<p>Ett "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.

Full textAbstract:
The use of ERP in organisations is very popular and many companies have embraced this paradigm without really questioning why. Problems therefore often arise and cause high costs which is a result of poor planning. The paradigm also has its origin in the traditional architectural design that creates a system that has difficulties to adapt to organizations that are constantly evolving. The purpose of this study is to provide a different view of how IT-systems can operate within an organization and show how standard systems can be structured. We emanated from a case study at Linköping University Library, where we studied the implementation and integration of a standard system called Symphony. This lead to a prototype model of a system architecture called LSA (Loose coupled Architecture Service). The results of this study show the benefits of a detailed project plan for an implementation process. It also shows there are new system architectures available instead of the old traditional ones. The criticism towards the innovative object-oriented architecture models evolved in early 2000, have been proved wrong as we demonstrate in this study.

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.

Full textAbstract:
As social interactions increasingly become exclusively online, there is a need for research on the role of identity and social identity in online platforms. Drawing on Symbolic Interactionist approaches to identity, namely Social Identity Theory and Identity Theory, as well as Signaling Theory, this study argues that actors will selectively use religious language to signal their credentials to an audience for the purpose of garnering prosocial behavior in the form of donations to their fundraising campaign. Using latent semantic analysis topic models to analyze the self-presentations of crowdsourcing campaigners on GoFundMe.com, this study found evidence for the presence of signaling to a religious identity online as well as a significant difference in the presentation of need for campaigns originating in areas with high reported religiosity compared to campaigns from areas of low religiosity. In comparison to other campaigns, campaigners engaging in religious signaling were significantly increasing their donations. I suggest that strategically chosen religious topics in online crowdfunding is an example of low-cost identity signaling and provides insight into how signaling happens online and the potential outcomes resulting from this cultural work.

O processo de tomada de decisão, em diferentes ambientes gerenciais, enfrenta um momento de mudança no contexto organizacional. Nesse sentido, Business Analytics pode ser visto como uma área que permite alavancar o valor dos dados, contendo ferramentas importantes para o processo de tomada de decisão. No entanto, a presença de dados em diferentes formatos representa um desafio. Nesse contexto de variabilidade, os dados de texto têm atraído a atenção das organizações, já que milhares de pessoas se expressam diariamente neste formato, em muitas aplicações e ferramentas disponíveis. Embora diversas técnicas tenham sido desenvolvidas pela comunidade de ciência da computação, há amplo espaço para melhorar a utilização organizacional de tais dados de texto, especialmente quando se volta para o suporte à tomada de decisões. No entanto, apesar da importância e disponibilidade de dados em formato textual para apoiar decisões, seu uso não é comum devido à dificuldade de análise e interpretação que o volume e o formato de dados em texto apresentam. Assim, o objetivo desta tese é desenvolver e avaliar um framework voltado ao uso de dados de texto em processos decisórios, apoiando-se em diversas técnicas de processamento de linguagem natural (PNL). Os resultados apresentam a validade do framework, usando como instância de demonstração de sua aplicabilidade o setor de turismo através da plataforma TripAdvisor, bem como a validação interna de performance e a aceitação por parte dos gestores da área consultados.The 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.
