Full textAbstract:
Services Science is a new research discipline that has received, over the last years, a growing attention from academia and practice. It combines research from various fields which have evolved more or less independently and is concerned with the development and management of service products. Whereas theories from organizational and marketing science usually capture the nature of
these products, engineering disciplines focus on shaping and developing these information goods, and the information systems field on integrating services as encapsulated application functionalities
by using standardized (XML) interfaces. All these research streams converge in the new interdisciplinary area of Services Science which integrates the principles, design, and management of economic and technical services.
For the fourth time, the \\\\\\\'International Symposium on Services Science (ISSS)\\\\\\\' offered an outstanding platform for the advancement and discussion of research in Service Science. In 2012, the ISSS focused on knowledge-intensive business services, also known as Smart Services, and their application in theory and practice. The ISSS was part of the Multi-Conference SABRE (Software, Agents and Services for Business, Research and E-Sciences, 24th-25th September 2012) and was held in Leipzig, Germany as a one-day event on the 25th September, 2012.
The symposium was organized by the Information Systems Institute and the Department of Computer Science at the University of Leipzig as well as the Institute for Applied Informatics (InfAI), Fraunhofer MOEZ and the Leipziger Informatik-Verbund (LIV). As reflected in the conference proceedings, the sessions included in the agenda dealt with Smart Services from different perspectives: Smart Services in Theory and Practice, Smart Services in Management and Application,
and Smart Services in High-Tech-Sectors. Although the official language of the conference is English, the authors had the opportunity to write their research contributions in English or German.

Resumo: O objetivo da presente pesquisa é analisar as abordagens futebolísticas nos roteiros, contos
e crônicas de Nelson Rodrigues, entre 1951 e 1970, a partir de uma perspectiva teórica
psicanalítica – haja vista os traumas, recalques e obsessões observáveis em suas obras. Se
Nelson Rodrigues, independentemente do gênero que escrevia, mantinha-se na intersecção
entre o factual e o fictício, pode-se constatar que, assim como a dramaticidade típica do
teatro rodrigueano adentra a crônica esportiva, o futebol – enquanto tema do cotidiano –
também ocupou um espaço na ficção, representada pelos contos e roteiros. Nesse sentido,
quais as conjunções utilizadas por Nelson Rodrigues, ao retratar o futebol nos roteiros,
contos e crônicas do período entre 1951 e 1970? O esporte nos roteiros e contos é o mesmo
dramatizado nas crônicas ou assume papel preponderante na psicologização de seus
personagens? E, em contrapartida, esse ponto de vista psicológico acerca dos personagens
adentra a crônica esportiva? A fim de solucionar as questões levantadas previamente, fez-se
necessário o uso da análise literária, proposta de Antonio Candido (1992, 2000), que
considera tanto as questões do texto por si só, quanto os aspectos do contexto que,
inevitavelmente, permeiam a obra. Junto a isso, contou-se ainda com alguns conceitos
psicanalíticos propostos por Sigmund Freud. Com base na análise das fontes, constatou-se
que, se na crônica esportiva, Nelson Rodrigues se utilizava da psicologia para falar do
complexo de vira-latas e do bem-estar do atleta, que se sentia inferior diante de estrangeiro,
nos contos e roteiros o autor estabelece o futebol como elemento de sublimação das
repressões cotidianas. A trama teatral, que também se reflete no conto, atua como um meio
de mostrar, de maneira prática, sob a forma de exemplo, os sentimentos em torno do
esporte, expostos na crônica.

Full textAbstract:
This thesis work is to do with the Information system of data boxes (ISDS) which is introduced from legislation's and user's point of view. Because the introduction of this system has influenced hundreds of thousands of subjects the main target of this thesis is to find out about the impact of the ISDS on users with the help of the analysis method. In this work firstly the data provided by the Ministry of Internal Affairs are examined and interpreted, secondly the results of the poll conducted by the author and then a cost-benefit analysis of the system from the users' point of view is carried out. The results of the work show that the ISDS was at the end of the examined period (2009 -- 2013) beneficial for its users and the total economic benefit for the respective period is 3.6 billion Czech crowns. This means that every crown spent on the operation of the system by the Ministry of Internal Affairs represents savings of 2 Czech crowns. The author of this work has come to the conclusion that the system is from a legislative, technological and economic point of view very well created. The author recommends to the system administrator its further development and also recommends to use its potential among thousands of OSVČ (the self-employed).

Full textAbstract:
Since events of September 11 and the subsequent conflicts surrounding the event, the war against terrorism has been constantly present. It has been used several methods and strategies to address these threats, including a method current in use, the targeting method. The method refers to use few but precise attacks to knock out key functions within these organizations, mostly individuals in the higher command and control structures within these organizations. The effectiveness of the method has been put in question when the majority of the terrorist organizations continue their strife, in some cases even increasing its intensity. The purpose of this study is to investigate which role the higher command plays in these organizations ability to wage war. This study utilize the organization ISIS as a representative for other similar Islamist terrorist organizations. The study use theories regarding network based groups and decentralized organizations in order to explain the structure of ISIS. The study shows that ISIS is an organization which has largely evolved into something other than what is described as an typical terrorist organization, the organization is more like one among other nations with a large and well structured organization, where management conditions are clear and well developed. ISIS can be a inconsistency in terrorist organizations, but may also have developed like the theoretician Galula named as the fourth step in the orthodox model of an terrorist or irregular force inevitable development in the struggle for control.

Full textAbstract:
Over the past year, cyber threats have been growing tremendously, which has led to an essential need to strengthen the organization's security. One way of strengthening security is to implement an information security management system (ISMS). Although an ISMS will help improve the information security work within the business, organizations struggle with its implementation, and significantly smaller organizations. That results in smaller organization's information being potentially less protected.This thesis investigates how an ISMS based on MSB can be simplified to make it suitable for a small organization to implement. This thesis aims to open for further research about how it can be simplified and if it has a value of doing it.The study is based on a qualitative approach where semi-structured interviews with experts were conducted. This thesis concludes that it is possible to simplify an ISMS based on MSB for a small organization by removing external analysis, information classification, information classification model, continuity management for information assets, and incident management. In addition, the study provides tips on what a small organization should think about before and during implementation.

Resumo: O presente trabalho de doutorado descreve o desenvolvimento de eletrodos íon-seletivos para cálcio, potássio, sódio e cloreto em sistema de injeção em fluxo e sua aplicação para determinação simultânea em sucos de frutas, bem como o desenvolvimento de eletrodos íon-seletivos de contato sólido com baixo limite de detecção. A construção dos eletrodos íon-seletivos para os íons cálcio, potássio, sódio e cloreto foi primeiramente realizado em estado estacionário para logo ser incorporada em sistema de injeção em fluxo. A otimização de parâmetros comuns, tais como: pH, tampão, volume de injeção, vazão, entre outros, possibilitaram a realização da determinação simultânea, utilizando um arranjo de eletrodos em série. O sistema FIA potenciométrico proposto foi satisfatório para determinação simultânea destes íons em amostras de sucos, e os resultados quando comparados com os obtidos pelo método de referência foram estatisticamente iguais num nível de confiança de 95%. Em relação ao desenvolvimento de eletrodos íon-seletivos com baixo limite de detecção, quatro eletrodos diferentes foram desenvolvidos para os íons prata, chumbo, cálcio e iodeto com excelente resposta nernstiana e limite de detecção na faixa nanomolar, que foram 2 nmol L para Ag, 1 nmol L para Pb, 4 nmol L para Ca e 10 nmol L para I. Isto foi conseguido pelo uso do polímero condutor, poli(3-octiltiofeno) como interface entre o contato sólido e a membrana polimérica, o copolímero metilmetacrilato-decilmetacrilato. Os eletrodos desenvolvidos mostraram resposta rápida e boa repetibilidade, sendo promissores para sua utilização em determinações em nível de traço
Abstract: The present work describes the development of ion-selective electrodes for calcium, potassium, sodium and chloride to be employed in flow injection analyses and its application for the simultaneous determination in samples, as well as, the development of solid contact ionselective electrodes with detection limit in the nanomolar range. The preparation of ion-selective electrodes for calcium, potassium, sodium and chloride was performed optimizing them in steady-state and then incorporated in simultaneous low injection analyses. The optimization of common parameters, such as: pH, buffer, injection volume, flow, etc., was performed looking for the simultaneous determination, using an array of electrodes in series. The proposed potentiometric FIA system was satisfactory for simultaneous determination of these ions in juice samples, and the results, when compared to the reference method, were statistically the same in the 95% of confidence level. In relation to the development of solid contact ion-selective electrodes with low detection limit, four different electrodes were developed for silver, lead, calcium and iodide, with excellent nernstian response and detection limit in the nanomolar range. The obtained detection limits were 2 nmol L for Ag, 1 nmol L for Pb, 4 nmol L for Ca e 10 nmol L for I. It was possible by using the conducting polymer, poly(3-octylthiophene) as an interface between the solid contact and polymeric membrane, methyl metacrylate decyl metacrylate copolymer. The electrodes presented short response time and good repetibility, being potentially useful for determination in trace levels

Resumo: Myrtaceae é conhecida como uma das mais complexas famílias de angiospermas. Myrcia teve sua última revisão taxonômica realizada há 153 anos e desde então inúmeras espécies novas foram descritas, deixando Myrcia como o segundo maior gênero da tribo Myrteae. O elevado número de espécies no gênero e a falta de uma revisão taxonômica completa e atualizada fez com que vários complexos de espécies mal delimitadas fossem formados em Myrcia. Um destes complexos é abordado no presente trabalho e inclui quatro espécies (M. laruotteana, M. lajeana, M. selloi e M. tomentosa) de ampla distribuição e grande variação morfológica, tornando difícil a separação entre os táxons. Neste estudo foram usados marcadores ISSR para investigar a correlação entre a variabilidade genética de populações destas espécies com aspectos morfológicos, geográficos, fitogeográficos e taxonômicos, a fim de esclarecer a delimitação das espécies. Levando em conta os resultados obtidos nestas análises, uma nova proposta de classificação específica é apresentada, com descrições dos táxons aceitos, dados de distribuição geográfica, floração e frutificação, e chave de identificação. No estudo de genética de populações com ISSR, o valor de diversidade genética encontrado (He = 0,215) foi mais baixo que o valor para espécies perenes, de distribuição ampla e fecundação cruzada. Isto pode ser explicado em partes pela auto-compatibilidade que as espécies do complexo M. laruotteana podem apresentar, como já relatado na literatura. Nenhum dos grupos que refletem aspectos morfológicos, geográficos e fitogeográficos testados apresentou boa estruturação genética, ou seja, nenhum deles mostrou alguma descontinuidade genética que pudesse representar os táxons envolvidos no complexo. Os grupos testados que representam a circunscrição taxonômica atual do complexo também não apresentaram boa estruturação genética. Os grupos formados a partir da análise Bayesiana mostraram melhor estruturação genética a partir da AMOVA (12% de variação entre as populações dentro dos grupos e 27% de variação entre os grupos). A análise Bayesiana juntamente com o dendrograma formado demonstra uma separação em dois grandes grupos, o primeiro formado por todas as populações de M. tomentosa, e o segundo contendo as populações das outras espécies misturadas. A partir destes resultados e levando em consideração toda a variação existente entre os extremos morfológicos das espécies, é proposta uma nova classificação para o complexo, com sinonimização de M. lajeana sob M. laruotteana. Myrcia tomentosa e M. laruotteana podem ser reconhecidas principalmente pelo indumento, geralmente denso na primeira e quase ausente na segunda. Myrcia selloi pode ser reconhecida pela queda dos remanescentes do hipanto e do cálice, deixando os frutos com uma cicatriz circular apical
Abstract: Myrtaceae is known as one of the most complex families of angiosperms. The last taxonomic revision of Myrcia was made 153 years ago and since then many new species were described, leaving Myrcia as the second largest genus of the tribe Myrteae. The high number of species in the genus and the lack of a complete and updated taxonomic revision resulted in many species complexes in Myrcia. One of these complexes is investigated in this work and includes four species (M. laruotteana, M. lajeana, M. selloi and M. tomentosa) with wide distribution and a lot of morphological variation, making it difficult to distinguish these taxa. This study used ISSR markers to investigate the correlation between the genetic variability of populations of these species with morphological, geographical, phytogeographic and taxonomic aspects, in order to clarify the delimitation of species. Taking into account the results obtained in these analyzes, a new proposal of specific classification is presented with descriptions of accepted taxa, geographical, flowering and fruiting data, and identification key. In the study of population genetics with ISSR, the value of genetic diversity (He = 0.215) was lower than the value for perennial, widely distributed and cross-fertilization species. This can be explained in part by self-compatibility that species within M. laruotteana complex apparently present, as previously reported in the literature. None of the groups that reflect morphological, geographical and phytogeographic aspects showed good genetic structure, i.e., none of them showed any genetic discontinuity that could represent the taxa involved in the complex. The groups represented by the current taxonomic circumscription of the complex also did not show good genetic structure. The groups formed from the Bayesian analysis showed better genetic structure from the AMOVA (12% variation among populations within groups and 27% variation between groups). The Bayesian analysis with the dendrogram formed showed two major groups, the first with all populations of M. tomentosa, and the second containing mixed populations from other species. From these results and taking into account the large amount of variation between the morphological extremes of the species, we propose a new classification for the complex, with the synonymization of M. lajeana under M. laruotteana. Myrcia tomentosa and M. laruotteana differ from each other mainly by the indumenta, which is dense in the former and almost absent in the latter. Myrcia selloi differs from the others by the caduceus remnants of the hypanthium and calyx, leaving circular apical scar on the fruit

Full textAbstract:
Med anledning av ISPS- kodens inträdande 2004 och personliga erfarenheter från fartyg och skyddsvaktsarbete har vi valt att fördjupa oss i ämnet portvaktens arbetsuppgifter. Vad vi har observerat sedan tidigare är att den allmänna uppfattningen bland ombordanställda är att portvakten är i vägen och det tar lång tid att komma till sin arbetsplats på fartyget.
Detta är en deskriptiv uppsats, där vi gjort en kvalitativ studie som bygger på intervju med vaktpersonal. Intervjun är sedan jämförd med de regler som finns för vakten i porten. Vi har avgränsat oss till att undersöka Göteborgs hamn, då denna var först i Europa att införa ISPS. Vi har intervjuat Magnus Rosenqvist, gruppchef på G4S i Göteborgs hamn. Detta har vi sedan jämfört med vad sjöbefälsstudenter på Högskolan i Kalmar har för erfarenheter och uppfattningar.
Vakten ansvarar för tillträdet till hamnområdet. Anledningen varför kontrollerna är så höga är för att upprätthålla hamnskyddet, inte fartygsskyddet. Vakten har samma ISPS- utbildning som resterande hamnpersonal, den utbildning en väktare måste inneha, men i Göteborgs hamn måste man dessutom vara skyddsvakt.
In connection with the ISPS- code's arising in 2004 and personal experiences from ships and security guarding, we have selected to deepen ourselves in the matter the gatekeeper’s duties. We have observed already that the general view among the vessel’s apployes, that the gatekeeper is in the way and it takes a long time to get to the workplace onboard the ship.
This is a descriptive essay, where we have done a qualitative study that builds on interview with local security personnel. The interview is then compared with the rules that are for the security guard in the gate. We have delimited ourselves to examining Gothenburg's port, because this is the first port in Europe to introduce the ISPS- code. We have interviewed Magnus Rosenqvist, squad commander at G4S in Gothenburg’s port. This result is then compared with the experiences and thoughts of students at Kalmar Maritime Academy.
The security guards are responsible for the access to the port area. The reason why the controls are so high is in order to maintain the port’s protection, not the ship’s protection. The security guard has the same ISPS education that all port personnel have, the education a general security guard must hold, but in Gothenburg’s port a security guard also must have a “skyddsvakt’s” education.

Full textAbstract:
In this study, I examine how terrorism is produced and consumed in communication. Using discourse analysis, I investigate how terrorism is constituted in the accounts of four women described in online news reports as having joined, or almost joined the so-called Islamic State (IS): “Alex,” constructed as having been lonely and flirted with IS; “Khadija,” presented as a schoolteacher turned member of IS’s all-women’s brigade; Laura, described as a woman whose partner abandoned her, who met a man online, and who brought her son with her to join IS; and Tareena, referred to as a health worker who brought her child with her to join IS. My analyses address how each interview can add to our insights about becoming a woman of IS. I make four arguments. First, terrorism is mobilized through interaction. Second, the double bind is a dynamic uniquely applicable to women because becoming a member of IS can be examined as an act of gender resistance. Third, accounts of becoming a woman of IS work as rhetoric designed to prevent other vulnerable people from being recruited. Fourth, terrorism is mobilized through narrative storytelling, especially through the use of paralinguistic features in the building of accounts. By researching terrorism as communication, and focusing in particular on four women’s interviews of their recruitment experiences, this dissertation contributes to new, applicable, and actionable interventions designed to counter and prevent the violence of terrorism, as well as to research about women, terrorism, and communication.

Resumo: O culto da deusa Ísis foi importante na religião egípcia, especialmente com relação às características de maternidade e de fertilidade. Este culto foi levado para fora das localidades egípcias, por diversos motivos, sendo inserido em outras culturas e identificado com as divindades locais. Na cultura romana, o culto isíaco esteve mais presente com o festival Navigium Isidis e com os rituais de iniciação nos mistérios da deusa, não perdendo as características que giram em torno da fertilidade e maternidade.
Abstract: The worship of goddess Isis was important to the Egypt religion specially related to the characteristics of maternity and fertility. This worship was taken outside from Egypt, for many reasons and it was incorporeted to others cultures and identified with local goddess. In the roman culture, the isiac worship was more presented in Navigium Isidis festival and with ritual of iniciation in the mysteries of the goddess, not losing the characteristics that are related to fertility and maternity.

Full textAbstract:
Dans la famille des idiophones, le terme de sistre occupe une acception large regroupant plusieurs instruments utilisés dans de nombreuses sociétés. Dans l’Antiquité, le terrain égyptien fournit un exemple de sistre, notamment attaché au culte de la déesse Hathor. Durant la période pharaonique et surtout à la Basse Époque, le sistre en alliage cuivreux semble se modifier. Il bascule ensuite dans le monde gréco-romain par le biais de la diffusion des cultes isiaques et subit de nouvelles modifications. Notre étude porte sur ce sistre isiaque, des premiers Lagides à l’extrême fin du IVe s. av. J.-C. jusqu’au IVe s. ap. J.-C. où il n’est plus attesté archéologiquement. L’étude de l’objet physique soulève plusieurs questionnements et demande la sélection de critères pour permettre une mise en série des realia. La typologie mise au point pour cet artefact nécessitait par ailleurs une comparaison avec le sistre pharaonique antérieur. Elle permet de mieux cerner les étapes de sa diffusion ainsi que les enjeux qui en découlent. Dans ses représentations et utilisations, le sistre isiaque revêt un aspect profondément polysémique. Principalement attribut de la déesse Isis, il est aussi porté ponctuellement par d’autres divinités ou représenté seul. Le sistre est également un instrument de musique et un instrument rituel utilisé dans les cérémonies et les processions, ou encore dans le domaine funéraire. Les différents types documentaires et contextes d’apparition de l’objet, s’ils ne sont pas présentés de façon exhaustive, sont abordés dans le but de mieux cerner les usages, pratiques et symboliques, liés à cet instrumentIn the family of idiophones, the term sistrum has a broad meaning, encompassing several instruments used in many societies. In ancient times, the Egyptian area provided an example of sistrum, especially attached to the cult of the goddess Hathor. During the Pharaonic period and especially in the Late Period, the coper alloy sistrum seems to be modified. Then it passes to the Greco-Roman world through the diffusion of isiac cults and goes through new modifications. Our study concerns this isiac sistrum, from the beginning of the Lagid dynasty to the end of the 4th century BC until the 4th century AD where it is no longer archaeologically attested. The study of the physical object raises several questions and calls for the selection of criteria to allow a serialization of the realia. The typology developed for this artefact also required a comparison with the previous pharaonic sistrum. It allows us to better identify the stages of its dissemination and the stakes arising from it. In its representations and uses, the isiac sistrum has a profoundly polysemic aspect. Primarily attributed to the goddess Isis, it is also worn punctually by other deities or represented alone. The sistrum is also a musical instrument and a ritual instrument used in ceremonies and processions, or in the funerary area. The variety of the documentary types and the contexts of appearance of the object, if not presented in an exhaustive way, are approached in order to better identify the practical, symbolic uses associated with this instrument

Assim, estudos genéticos de algumas populações permitem interpretar a comunidade e extrapolar os resultados para outras espécies similares. Myrsine umbellata, é uma espécie arbustiva, amplamente distribuída na Floresta Atlântica, umbellata devem priorizar amostras populacionais que sejam internas, dado que estas são uma importante fonte de germoplasma para a conservação in situ. pioneira, facilitadora em áreas de regeneração natural, com dispersão zoocórica, sendo seus frutos importantes na dieta da avifauna. Com o objetivo de identificar a diversidade genética entre e dentro das populações, foram amostradas seis populações de M. umbellata, sendo elas: Macieira, Ibitirama, Iúna, Parque Estadual do Forno Grande, Santa Teresa e Parque Estadual da Pedra Azul, totalizando 63 indivíduos. Foram utilizados 10 marcadores moleculares ISSR para amplificações de 129 locos, obtendo 100% de polimorfismo para nove primers. Os dados foram submetidos à análise de similaridades entre indivíduos pelo coeficiente de Jaccard, evidenciando maior similaridade entre as populações de Ibitirama e Iúna. O índice de diversidade de Nei (He) e o índice de Shannon (H) nas populações variaram de 0,28 a 0,18 e 0,18 a 0,12, respectivamente, sendo a população da Macieira a que apresentou os maiores valores e a população de Ibitirama os menores valores. A AMOVA mostrou que a maior parte da diversidade genética ocorre dentro das populações (67,41%) do que entre (32,58%), com a estatística ΦST apresentando um alto nível de diferenciação genética em 0,32. O fluxo gênico estimado para o conjunto de populações foi alto (Nm = 1,24), mas acredita-se que esse valor esteja atribuído a um fluxo gênico histórico de quando as populações faziam parte de metapopulações, antes dos processos de fragmentação florestal. Foi feita também uma AMOVA para analisar par a par os valores de ØST das populações e os valores encontrados indicam que as populações estão de moderada a altamente estruturadas. Foi utilizado o método de agrupamento UPGMA tanto para indivíduos quanto para populações, e dois grandes grupos foram formados, confirmado pela avaliação feita pelo programa STRUCTURE que obteve melhor K igual a 2. A manutenção da variabilidade genética em populações é a base da conservação das espécies, dessa forma, os dados encontrados indicam que estratégias de conservação para populações de M. um

Detta examensarbete handlar om fartygsskydd och rollen som SSO på olika fartygstyper. Syftet med undersökningen var att ta reda på vilket sätt fartygstypen och fartområdet fartyget går i påverkar hur man ombord arbetar med fartygsskyddet och ISPS. Denna undersökning genomfördes under sommaren och hösten 2015 genom kvalitativa semistrukturerade intervjuer med SSO:erna på fyra fartyg av olika typ i olika fartområden. Fartygen i undersökningen består av ett kryssningsfartyg i oceanfart, ett tankfartyg i europafart, ett biltransportfartyg i oceanfart samt en färja i närfart. Resultatet av vår undersökning visar att det finns skillnader mellan både de undersökta fartygstyperna och fartområdena samt att detta påverkar hur de intervjuade SSO:erna uppfattar sin roll. Resultatet pekar på att den största skillnaden i organiseringen av fartygsskyddet finns mellan de två huvudtyperna av fartyg i studien, dvs. passagerarfartyg och lastfartyg, och att den skillnaden till stor del kan förklaras av besättningens storlek.This thesis is about ship security and the role of the SSO on different types of vessels. The purpose of the survey was to find out how the ship type and trade area of the ship affects how the on-board work with security and ISPS is conducted. The study was carried out during the summer and autumn 2015 by making qualitative semi-structured interviews with the SSOs on four vessels of different type in different trade areas. The vessels in the survey consist of a cruise ship in ocean traffic, a tanker in European traffic, a car carrier in world-wide ocean traffic and a ferry in short voyage traffic. In the study it was concluded that there are differences between both the investigated vessel types and trade areas, and that this affects how the interviewees: the SSOs perceive their role. The result indicates that the largest difference in the organization of ship security is found between the two main types of vessels in the study, between passenger ships and cargo ships, and that this difference can largely be explained by the size of the crew.

Resumo: Sistemas embarcados modernos são compostos de SoC heterogêneos, variando entre processadores de baixo e alto custo. Apesar de processadores RISC serem o padrão para estes dispositivos, a situação mudou recentemente: fabricantes estão construindo sistemas embarcados utilizando processadores RISC - ARM e MIPS - e CISC (x86). A adição de novas funcionalidades em software embarcados requer maior utilização da memória, um recurso caro e escasso em SoCs. Assim, o tamanho de código executável é crítico, porque afeta diretamente o número de misses na cache de instruções. Processadores CISC costumavam possuir maior densidade de código do que processadores RISC, uma vez que a codificação de instruções com tamanho variável beneficia as instruções mais usadas, os programas são menores. No entanto, com a adição de novas extensões e instruções mais longas, a densidade do CISC em aplicativos recentes tornou-se similar ao RISC. Nesta tese de doutorado, investigamos a compressibilidade de processadores RISC e CISC; SPARC e x86. Nós propomos uma extensão de 16-bits para o processador SPARC, o SPARC16. Apresentamos também, a primeira metodologia para gerar ISAs de 16-bits e avaliamos a compressão atingida em comparação com outras extensões de 16-bits. Programas do SPARC16 podem atingir taxas de compressão melhores do que outros ISAs, atingindo taxas de até 67%. O SPARC16 também reduz taxas de cache miss em até 9%, podendo usar caches menores do que processadores SPARC mas atingindo o mesmo desempenho; a redução pode chegar à um fator de 16. Estudamos também como novas extensões constantemente introduzem novas funcionalidades para o x86, levando ao inchaço do ISA - com o total de 1300 instruções em 2013. Alem disso, 57 instruções se tornam inutilizadas entre 1995 e 2012. Resolvemos este problema propondo um mecanismo de reciclagem de opcodes utilizando emulação de instruções legadas, sem quebrar compatibilidade com softwares antigos. Incluímos um estudo de caso onde instruções x86 da extensão AVX são recodificadas usando codificações menores, oriundas de instruções inutilizadas, atingindo até 14% de redução no tamanho de código e 53% de diminuição do número de cache misses. Os resultados finais mostram que usando nossa técnica, até 40% das instruções do x86 podem ser removidas com menos de 5% de perda de desempenho
Abstract: Modern embedded devices are composed of heterogeneous SoC systems ranging from low to high-end processor chips. Although RISC has been the traditional processor for these devices, the situation changed recently; manufacturers are building embedded systems using both RISC - ARM and MIPS - and CISC processors (x86). New functionalities in embedded software require more memory space, an expensive and rare resource in SoCs. Hence, executable code size is critical since performance is directly affected by instruction cache misses. CISC processors used to have a higher code density than RISC since variable length encoding benefits most used instructions, yielding smaller programs. However, with the addition of new extensions and longer instructions, CISC density in recent applications became similar to RISC. In this thesis, we investigate compressibility of RISC and CISC processors, namely SPARC and x86. We propose a 16-bit extension to the SPARC processor, the SPARC16. Additionally, we provide the first methodology for generating 16-bit ISAs and evaluate compression among different 16-bit extensions. SPARC16 programs can achieve better compression ratios than other ISAs, attaining results as low as 67%. SPARC16 also reduces cache miss rates up to 9%, requiring smaller caches than SPARC processors to achieve the same performance; a cache size reduction that can reach a factor of 16. Furthermore, we study how new extensions are constantly introducing new functionalities to x86, leading to the ISA bloat at the cost a complex microprocessor front-end design, area and energy consumption - the x86 ISA reached over 1300 different instructions in 2013. Moreover, analyzed x86 code from 5 Windows versions and 7 Linux distributions in the range from 1995 to 2012 shows that up to 57 instructions get unused with time. To solve this problem, we propose a mechanism to recycle instruction opcodes through legacy instruction emulation without breaking backward software compatibility. We present a case study of the AVX x86 SIMD instructions with shorter instruction encodings from other unused instructions to yield up to 14% code size reduction and 53% instruction cache miss reduction in SPEC CPU2006 floating-point programs. Finally, our results show that up to 40% of the x86 instructions can be removed with less than 5% of overhead through our technique without breaking any legacy code

Full textAbstract:
Cette thèse porte sur l’étude du comportement d’arbres aléatoires issus de l’algorithmique. Nous utilisons des techniques probabilistes pour étudier des objets aléatoires liés aux arbres. Outre le chapitre 1, dans lequel sont définis formellement plusieurs types d’arbres aléatoires et où sont introduits les résultats principaux, la thèse est composée de trois parties qui portent chacune sur l’étude d’un phénomène aléatoire. Nous établissons dans un premier temps un résultat sur l’asymptotique de la mesure d’occupation d’une marche aléatoire branchante dont l’arbre sous-jacent est un arbre binaire de recherche (ABR). Avec des hypothèses très faibles sur les incréments des marches, nous montrons que cette mesure, une fois renormalisée, converge vers une mesure déterministe qui est liée à la loi stable dont le domaine d’attraction contient la loi des incréments. La preuve de ce résultat repose, entre autres, sur les propriétés fondamentales de la structure des ABRs comme le résultat de Louchard sur la profondeur typique d’un noeud. Cette convergence permet alors d’obtenir des résultats sur des objets liés à l’ABR : les fragmentations homogènes de l’intervalle ]0, 1[ et les arbres récursifs. La deuxième étude traite aussi des ABRs. On s’intéresse au profil de l’arbre (nombre de feuilles à chaque profondeur) en regardant les feuilles selon les types définis par Dekking : les bras, feuilles dont le frère est un noeud interne, et les jambes, feuilles dont le frère est aussi une feuille. On utilise un vecteur dont les coordonnées sont les polynômes appelés polynômes de niveau des bras et des jambes. Les coefficients d’indice k des polynômes de niveau sont respectivement le nombre de bras et de jambes à la hauteur k dans l’ABR de taille n. On obtient, en comparant les deux projections du vecteur sur les sous-espaces propres de la matrice d’évolution, une convergence L2 et presque sûre d’une martingale vectorielle, liée au profil, vers un vecteur associé à la limite de la martingale de Jabbour. Enfin, le dernier chapitre concerne un autre type d’arbres, les tries des suffixes. Ces arbres sont définis à partir d’un mot infini et leur aléa est donné par la source qui génère ce mot. Nous considérons ici une source dynamique -mélangeante. Nous montrons que la hauteur de saturation de l’arbre à n clefs, renormalisée par ln n, converge presque sûrement vers une constante liée à la source. L’étude de ce paramètre se traduit naturellement comme un problème de temps d’apparition de mots que nous résolvons grâce aux travaux de Abadi et Vergne sur le sujetThe aim of this thesis is the study of the behavior of trees used in analysis of algorithms. We use probabilistic techniques to study various random objects connected with trees. We formally define the trees we deal with and introduce our main results in chapter one. Each of the three other parts of the thesis contains a specific random phenomenon. We first establish a result on the asymptotics of the rescaled occupation measure of a branching random walk on binary search trees (BSTs). Under weak hypothesis on the increments, we show that this measure converges to a deterministic measure depending on the stable law whose domain of attraction contains the law of the increments. The proof is based on some fundamental properties of the structure of BST. One of them is the result by Louchard on the height of a typical node. This convergence allows to obtain results on two other objects associated to the BST : homogeneous fragmentations of ]0, 1[ and recursive trees. The second study is also on BSTs. We study the profile of the tree (number of leaves at each level) specifying the types of the leaves : arms are the leaves whose brother is an internal node and feet are the leaves whose brother is also a leaf. We use a vector whose coordinates are the level polynomials of arms and feet. The coefficient of order k of these polynomials is the number of arms and feet at level k in the BST of size n. Comparing the two projections of this vector on the eigenspaces of a so-called evolution matrix, we obtain an almost sure and a L2-convergence of a martingale vector, connected to the profile, to a vector associated to the limit of the Jabbour martingale. Finally, the last part deals with another kind of random trees : the suffix trees. These trees are defined from an infinite word and its randomness is given by the source that creates the word. Here we are concerned with -mixing sources. We prove that the fill-up level of a suffix tree with n keys, normalized by log n, converges almost surely to a constant depending on the source. By definition of the suffix trees, the study of this parameter happens to be a word apparition time issue. We obtain the convergence using results of Abadi and Vergne in this field

Les alcaloïdes sont des composés largement présents dans la nature. L'étendue croissante des propriétés pharmacologiques de ceux extraits d'une grenouille néotropicale, Dendrobates pumilio, a suscité un intérêt particulier pour leur étude, tant du point de vue synthétique que biologique. L'intérêt suscité par l'alcaloïde (-)-205B au sein de notre laboratoire est dû non seulement au défit que représente sa structure tricyclic de type 8b-azaacénaphthylène, mais aussi par l'activité biologique prometteuse vis à vis de certains troubles neuronaux.Une stratégie de synthèse efficace et hautement stéréosélective, a été développée conduisant à l’alcaloïde (-)-205B. Cette approche synthétique est basée sur trois transformations caractéristiques pour la constitution du noyau tricyclique et pour la mise en place des principaux centres stéréogènes : une 2+2 cycloaddition, une réaction de Mannich vinylogue et une cyclisation aza-Prins. Parallèlement à cette synthèse totale, une nouvelle méthodologie de transfert de chiralité a été développée par alkylation stéréosélective via un lien sililé permettant de résoudre la difficulté apparue dans l'approche précédenteAlkaloids are widely occurring compounds in nature. The increasing scope of pharmacological properties displayed by the alkaloids extracted from a neotropical frog Dendrobates pumilio has arouse an intense interest in their study, both from a synthetic and biological aspect. The interest toward the alkaloid (-)-205B has not been considered in our laboratory solely because of the challenged 8b-azaacenaphthylene ring structure, but also was inspired by the promising biological activity it might possess against neuronal disorders.An efficient and highly stereoselective synthetic strategy was developed for the synthesis of the alkaloid (-)-205B. This approach features three characteristic transformations for building up the tricyclic core and installing the main stereochemistry: a 2+2 cycloaddition, a vinylogous Mannich reaction and an aza-Prins cyclization. In tandem with this total synthesis, a novel methodology was developed focusing on the stereo-directed alkylation based on silicon-tethered chemistry that comes up as an efficient solution for a difficulty encountered within the earlier approach

Le présent travail se veut une contribution à l’extension du domaine des applications de la théorie des chemins rugueux à travers l’étude de la convergence des processus discrets, qui permet un nouveau regard sur plusieurs problèmes qui se posent dans le cadre du calcul stochastique classique. Nous étudions la convergence en topologie rugueuse, d’abord des chaînes de Markov sur graphes périodiques, ensuite des marches de Markov cachées, et ce changement de cadre permet d’apporter des informations supplémentaires sur la limite grâce à l’anomalie d’aire, invisible en topologie uniforme. Nous voulons montrer que l’utilité de cet objet dépasse le cadre des équations différentielles. Nous montrons également comment le cadre des chemins rugueux permet d’en- coder la manière dont on plonge un modèle discret dans l’espace des fonctions continues, et que les limites des différents plongements peuvent être différenciées précisément grâce à l’anomalie d’aire. Nous définissons ensuite les temps d’occupation itérés pour une chaîne de Markov et montrons, en utilisant les sommes itérées, qu’ils donnent une structure combinatoire aux marches de Markov cachées. Nous proposons une construction des chemins rugueux en passant par les sommes itérées et la comparons à la construction classique, faite par les intégrales itérées, pour trouver à la limite deux types de chemins rugueux différents, non-géométrique et géométrique respectivement. Pour finir, nous illustrons le calcul et la construction de l’anomalie d’aire et nous donnons quelques résultats supplémentaires sur la convergence des sommes et temps d’occupation itérésThrough the present work, we hope to contribute to extending the domain of applications of rough paths theory by studying the convergence of discrete processes and thus allowing for a new point of view on several issues appearing in the setting of classical stochastic calculus. We study the convergence, first of Markov chains on periodic graphs, then of hidden Markov walks, in rough path topology, and we show that this change of setting allows to bring forward extra information on the limit using the area anomaly, which is invisible in the uniform topology. We want to show that the utility of this object goes beyond the setting of dierential equations. We also show how rough paths can be used to encode the way we embed a discrete process in the space of continuous functions, and that the limits of these embeddings dier precisely by the area anomaly term. We then define the iterated occupation times for a Markov chain and show using iterated sums that they form an underlying combinatorial structure for hidden Markov walks. We then construct rough paths using iterated sums and compare them to the classical construction, which uses iterated integrals, to get two dierent types of rough paths at the limit: the non-geometric and the geometric one respectively. Finally, we illustrate the computation and construction of the area anomaly and we give some extra results on the convergence of iterated sums and occupation times

Nanoscience and nanotechnology are areas that have a great potential for new materials and new applications development. Recently many researches are using the nanotechnology concept to create Portland concrete composites, where they look for the comprehension of the hydration of cement particles and addition of nanometrics (nm) particles, either nano-silica or nanofibres. In the last decades, the majority of theprogress in the performance of cimentitious materials had been carried through the optimization of the grain stacking and, over all, through the reduction of the capillary porosity with the rational use of chemical additives more and more efficient. This study investigated the effect of the addition of nanoparticles of ceramic montimorillonita at Portland cement concrete. For such, two working conditions were chosen, ratio water /cement (0.45 / 0.50 / 0.55), and the following quantities of nanoceramic 0%, 2% and 4%. We analyzed the following parameters: workability, flux of the water flowing, compressive strength and tensile strength. The addition of nanoceramic caused a reduction in workability, which was expected. The results of axial compression for 28 days showed an improvement of 11% and 14% depending on the ratio water / cement.In the case of tensile strength by diametrical compression, the best option was to 4% of nanoceramic. In this case, the improvement was 6% for the ratio water / cement equal to 0.55 and 18% and 21% for 0.45 and 0.50, respectively. The addition of nanoceramic seems to be an excellent option for the preparation of Portland cement concrete. The nanoceramic presented pozzolanic activity.A nanociência e a nanotecnologia são áreas que apresentam grande potencial para o desenvolvimento de novos materiais e novas aplicações. Recentemente inúmeros pesquisadores estão utilizando o conceito de nanotecnologia para criação de compósitos de cimento Portland, na qual se busca a compreensão da hidratação daspartículas de cimento e a adição de partículas nanométricas (nm), seja nanosílica ou nanofibras. A maioria dos avanços no desempenho dos materiais cimentícios conseguidos nas últimas décadas foram realizados através da otimização dos empacotamentos granulares e, sobretudo, pela redução da porosidade capilar com a utilização racional de aditivos químicos cada vez mais eficientes. Neste estudo foi investigado o efeito da adição de nanopartícula cerâmica de montimorillonita ao concreto de cimento Portland. Para tal foram escolhidas duas condições de trabalho, relação água/cimento (0,45 / 0,50 / 0,55), e as seguintes quantidades de nanocerâmica 0%, 2% e 4%. Foram analisados os seguintes parâmetros: trabalhabilidade, fluxo de água passante, resistência à compressão e tração. A adição da nanocerâmica causou uma redução na trabalhabilidade, o que já era esperado. Os resultados de compressão axial para 28 dias mostraram uma melhora de 11% e 14% dependendo da relação água/cimento. Já no caso da resistência à tração por compressão diametral, a melhor opção foi a de 4% de nanocerâmica. Neste caso, a melhora foi de 6% para a relação água/cimento igual a 0,55 e de 18% e 21% para 0,45 e 0,50, respectivamente. A adição de nanocerâmica parece ser uma ótima opção para preparação de concretos de cimento Portland. A nanocerâmica apresentou atividade pozolânica.

In the contemporary world has been more and more observed the existence of reinforced concrete structures deteriorated by fast and intense degeneration processes, fact that induces the uncertainty of its safety and stability. Such situation, in many cases, is motivated by the lack of knowledge about the processes and degradation mechanisms, as well as for the absence of tests that appreciate, evaluate and esteem, the concrete durability adequately, once the control and evaluation requirements, adjusted or not, continue to be the amount of cement used in the concrete production and water/cement ratio. This investigation work intended to appraise the reliability and efficiency of the traditional tests used in the inspection and evaluation of the concrete durability in structures and constructions, in order to stipulate those that may be considered as the most appropriate or suitable, becoming, parameter and reference for analysis from this point on. The samples used in the experiments were extracted of old structures, considered as durable, selected among of the four classes of environmental aggressiveness foreseen in the ABNT specifications. Starting from the extracted specimens, some physical and mechanical concrete properties were appraised, as well as supplementary evaluations were made to provide the knowledge of concrete microstructure, to identify the presence of possible contaminants and, finally, to foresee the useful life of each one of the structures. Starting from a comparative study made among the structures, it was possible to infer that, the ultrasonic tests and absorption of water for capillarity showed to be the most efficient process in the analysis of the concrete durability. The present work shows a collection of pictures typifying the most observed pathologies of reinforced concrete deteriorated structures.No mundo contemporâneo tem-se observado, cada vez mais, a existência de estruturas de concreto armado deterioradas por velozes e ferozes processos de deterioração, fato que induz a incerteza quanto à sua segurança e estabilidade. Tal situação, em muitos casos, é motivada pelo desconhecimento dos processos e mecanismos de degradação, bem como pela ausência de ensaios que possam apreciar, avaliar e estimar, com propriedade, a durabilidade dos concretos, uma vez que os requisitos de controle e avaliação, normalizados ou não, continuam sendo a quantidade de cimento utilizado na produção dos concretos e a relação água/cimento.Este trabalho de investigação avalia a confiabilidade e eficiência dos tradicionais ensaios utilizados na inspeção e avaliação da durabilidade dos concretos existentes em estruturas e construções, no intuito de determinar aqueles que podem ser considerados como os mais apropriados ou adequados, tornando-se, a partir de então, parâmetro e referência para análise. As amostras utilizadas nos experimentos foram extraídas de estruturas antigas, consideradas como duráveis, selecionadas dentro das quatro classes de agressividade ambiental previstas na normalização brasileira. A partir dos testemunhos extraídos, foram avaliadas algumas propriedades físicas e mecânicas dos concretos, e foram realizadas avaliações complementares que permitiram conhecer a microestrutura dos concretos, identificar a presença de possíveis contaminantes e, finalmente, prever a vida útil de cada uma das estruturas.A partir de um estudo comparativo realizado entre as estruturas, foi possível concluir que os testes de ultra-sonografia e absorção de água por capilaridade mostraram ser os mais eficientes na análise da durabilidade do concreto. O presente trabalho apresenta um acervo de fotografias que tipificam as patologias mais observadas em estruturas de concreto armado deterioradas.

The increasing usage of mixed steel/concrete pillars in Brazil, without the necessary constructive details, is a relevant factor in the study of the adherence between steel and concrete. Many factors, related to the concrete, to the steel tube and to the preparation of the mixed pillars in the construction site, affect the structural technical performance of the pillars. One can find in the literature theoretical and experimental studies covering the subject, but there are scant information concerning the role of the surface of the steel tubes on their adherence to the internal concrete. This role is studied in the present research, employing 36 push-out laboratory experiments and 34 numerical simulations of compression tests. Three cross-section shapes were considered (circular, square and rectangular) and 12 samples, 800 mm long, for each cross-section, were evaluated. Half of the samples had their internal steel surfaces chemically conditioned. The numerical analysis involved three steps: the first involved loading only on the concrete nucleus, the second considered the simultaneous loading of the steel tube and of the concrete nucleus, and finally each of these elements were loaded separately. The experimental and numerical results indicated a significant increase in the steel/concrete adherence after the internal surface conditioning of the steel tubes. The numerical simulations described adequately the experimental results.A crescente demanda na utilização de pilares mistos, sem os devidos cuidados construtivos, torna-se um fator relevante para o estudo da aderência entre o aço e o concreto. Existe um grande número de fatores que atuam no comportamento estrutural que influencia na performance técnica dos pilares mistos, sejam relacionados ao concreto, ao aço ou à execução no canteiro de obras. Na literatura existente encontram-se estudos teóricos e experimentais abordando o tema, mas existe pouca informação sobre a influência do estado superficial das paredes tubulares na aderência com o concreto. O presente trabalho avalia, através de 36 ensaios laboratoriais de pushout e 34 simulações computacionais à compressão, a interferência da aderência interna entre o núcleo de concreto e as paredes do perfil em aço patinável. Foram ensaiados 12 corpos-de-prova mistos tubulares preenchidos com concreto para cada seção geométrica (circular, quadrada e retangular), com 800 mm de altura. A formação da pátina foi acelerada em metade das amostras internamente. A análise computacional foi dividida em 3 partes, sendo a primeira análise com carregamento somente no núcleo de concreto, a segunda com atuação no conjunto e a terceira carregando os materiais isoladamente. Os resultados do programa experimental demonstraram um aumento significativo da tensão de aderência entre o aço e o concreto com a presença da oxidação interna nos perfis tubulares. A análise computacional simulou o comportamento real dos materiais para as situações estudadas.

The factors mixture water grade and launch method have great influence on final characteristics of refractory concrete in the fresh and harden states considering its performance in relation to launch and utilization conditions, being, besides aspects like the lost of mechanical resistance, directs agents on the appearance of pores and microfissures, elements responsible to material permissiviness, harmful material penetration and its mineral and crystalline structure. Other aspects, related to the industrial dosage, can also influence in these phenomenons like, for example, the form and reactivity of addition of thin powders which can be essential for good performance of the refractory concrete mixture when it is extracted the conscious use of additives from them. This work has searched evaluate the influence of three variables: water grade, vibration method, qualitative and quantitative variations of thin dust on the appearance of pores in aluminous refractory concretes of low cement grade and the results related to the growth of permeability seen from them. Samples derived of a concrete utilized on industrial refractories have been collected and they have been correlated with the analyzed standard material. The variations have been divided in twelve main groups, by three factors, which have been done tests related to the penetration of gases and water in these materials and compared for the verification of influence of the variables on the behavior of the samples. The results have showed the great influence of mixture water grade on the appearance of opened and close pores of the materials, being these the main responsible for the generation phenomenon of pores. In the background, it have been evidenced that the influence of vibration conditions on the appearance of pores in the material is much smaller than the influence of the variable water grade although being very significant. The qualitative variation of thin powders has alto resulted in the appearance of pores due to the lost of fluidity and packing properties. The quantitative variation of theses has showed great importance of them for the huge reduction of the pore volume in the material. The efficacy of the tests used in this research has been confirmed and they can be reproduced in local works with little laboratorial structures due to the simplicity of execution.Os fatores teor de água de mistura e método de lançamento têm grande influência nas características finais do concreto refratário nos estados fresco e endurecido, considerando seu desempenho frente às condições de lançamento e de utilização, sendo, além de fomentadores de aspectos como a perda de resistência mecânica, agentes diretos no surgimento de poros e microfissuras, elementos estes responsáveis para a permissividade do material à penetração de materiais nocivos à sua estrutura mineralógica e cristalina. Outros aspectos, agora ligados à dosagem industrial, podem influenciar também tais fenômenos, como, por exemplo, a forma e a reatividade de adições de pós finos, que podem ser essenciais para bons desempenhos da mistura dos concretos refratários quando delas se extrai o uso consciente de tais aditivos. Este trabalho buscou avaliar a influência das três variáveis teor de água, método de vibração e variações qualitativa e quantitativa de pós finos, sobre o surgimento de poros em concretos refratários aluminosos de baixo teor de cimento e os resultados relacionados ao aumento da permeabilidade apresentado pelos mesmos. Foram tomadas amostras derivadas de um concreto existente utilizado na indústria de refratários e correlacionados os resultados das mesmas com os do material padrão analisado. As variações se dividiram em doze grupos principais, pela conjugação dos três fatores, sendo realizados ensaios relacionados à penetração de gases e água em tais materiais e comparação para verificação da influência das variáveis no comportamento das amostras. Os resultados apontaram a grande influência no teor de água da mistura no surgimento de poros abertos e fechados dos materiais, sendo esta a principal responsável pelo fenômeno de geração de poros. Em segundo plano, foi comprovado que a influência das condições de vibração no surgimento de poros no material, apesar de significativa, é bem menor do que a influência da variável teor de água. A variação qualitativa dos finos também resultou em surgimento de poros devido à perda de propriedades de fluidez e empacotamento, já a variação quantitativa destes demonstrou a grande importância dos mesmos para a redução drástica do volume de poros no material. A eficácia dos ensaios utilizados na pesquisa foi confirmada, podendo estes, devido à simplicidade de execução, ser reproduzidos em frentes de serviço com pouca estrutura laboratorial.

The goal of this study is to present the effects of the different types of coarse aggregate on the mechanical properties of concrete: compressive strength and secant modulus of elasticity (MOE). Limestone, gneiss, dolomite and basalt were used as coarse aggregates. These aggregates came from six different regions in the state of Minas Gerais. ABNT type CP III RS cement and natural sand, as fine aggregate, were employed in the fabrication of the concrete. The concrete mix proportion was based on environmental class II of NBR 6118: minimum characteristic compressive strength equal to 25 MPa and water cement ratio 0.60. The mechanical properties were evaluated 3, 7, 14, 21 and 28 days after casting the concrete. The test results indicate expressively the better performance of the concretes fabricated with dolomite and basalt aggregates. Good correlation was achieved between the measured MOE values for the different concretes with the values calculated employing expressions in terms of the compressive strength suggested by NBR 6118, ACI 318, EUROCODE 2 and CEB 1990.O principal objetivo do estudo foi avaliar a influência do agregado graúdo de diferentes origens mineralógicas nas propriedades mecânicas do concreto: resistência à compressão e módulo de deformação. Para isto foram produzidos concretos com quatro tipos deagregados: calcário, gnaisse, dolomito e basalto, perfazendo um total de seis amostras obtidas de seis cidades do Estado de Minas Gerais: duas amostras de agregado de calcário (Belo Horizonte e Montes Claros), duas amostras de agregado de gnaisse (Passos e Guaxupé), uma amostra de agregado de basalto (Uberlândia) e uma amostra de agregado de dolomito (Patos de Minas). No estudo foi utilizado um único lote de cimento do tipo CP III 40 RS, areia artificial quartzosa e um mesmo aditivo plastificante. Os concretos analisados foram especificados segundo a classe de agressividade II da NBR 6118:2003 que prescreve concreto com resistência característica à compressão (fck) mínima de 25,0 MPa e uma relação água/cimento 0,60. As propriedades mecânicas dos diversos concretos foram avaliadas nas idades de 3, 7, 14, 21 e 28 dias após a fabricação. Os resultados indicam um desempenho melhor dos concretos produzidos com agregado graúdo de dolomita e basalto. Uma boa correlação foi obtida entre os valores medidos do módulo de deformação para os diferentes concretos com os valores calculados pelas expressões sugeridas pela NBR 6118, ACI 318, EUROCODE 2 e CEB 1990.

This work aims to investigate the bond strength of the finishing coat of mortar applied onto a ceramic block (brick) masonry, focusing on the analysis of the microstructure of the mortar/substrate interface, correlating to mechanical behavior of the mortar and the addition of hydrated lime in the mortar. Five distinct mortar types applied on the dry ceramic block substrate were assessed, using techniques for preparation and implementing, which are common at the construction site. The study was carried out using the scanning electron microscope with EDS microanalyzer (SEM-EDS), in order to identify the main hydration products present at the interface. Also, X-ray fluorescence spectrometry (XRF) was used to verify the depth of penetration of the hydration products, moreover analysis of characterization of the mortar in hard and plastic form. The results showed evidence that the main phase responsible for the bond strength between the plaster and the ceramic block is etringite. The adherence occurs by the interlocking of etringite crystals and their penetration within the pores of the substrate, which were observed inside these pores until a depth of 500µm. This penetration was confirmed by the variations in the concentrations of related chemical elements, depending on depth, by the XRF technique. It wasnt observed any direct relation between the calcium penetration depth and the bond strength. The depth and calcium penetration quantity is related to the binders quantity, inother words, ciment and/or lime. Different morphologies of the hydration products of the binders have been observed. The crystals formed at the interface are more euhedral and larger than the rest of the matrix and have a preferential orientation, perpendicular to the surface of the block. In this region, the presence of etringite is predominant and, in lower concentrations, there is also CSH (calcium silicate hydrate) and calcite. This is due to the increased mobility of sulfate, calcium and aluminum ions during the cement hydration and the proximity to the porous substrate, which provides the suction of the ions-bearing fluid to its interior. Different morphologies of the etringite crystals were also observed for the various mortar types used, probably caused by the variation of the contents of lime and binder in the mortar. The lime variation also influenced the mortar bond extension and thickness, in this way, affecting the strength values and rupture type (form). It was observed in the dig up tests that, after the rupture of the mortar, a thin later remains bonded to the brick, seen at naked eye, showing that the rupture happened due to the consistency lack of the mortar close to the interface, around 200µm far. This behavior makes clear that the rupture didnt occur along the range full of etringita, but within the mortar layer, near the contact surface.Este trabalho investiga a resistência de aderência de revestimentos argamassados sobre a alvenaria de blocos cerâmicos, concentrando-se na análise da microestrutura da interface argamassa/substrato, correlacionando-se ao comportamento mecânico da argamassa e à adição de cal hidratada na argamassa. Neste estudo foram avaliados cinco traços distintos, composto de cimento:cal:areia (1:0:6; 1:1:6; 1:2:8; 1:2:10; 0:1:6), aplicados sobre substrato de bloco cerâmico seco, com a utilização de técnicas de preparação e aplicação comuns em canteiros de obra. Para a análise foi utilizada a técnica de microscopia eletrônica de varredura com microanalisador EDS (MEV-EDS), a fim de identificar os principais produtos de hidratação presentes na interface. A análise por espectrometria de fluorescência de raios-X (FRX) foi utilizada para verificar a profundidade de penetração dos produtos de hidratação, além de ensaios de caracterização da argamassa nos estados plástico e endurecido. Os resultados dos estudos microestruturais demonstraram indícios de que a principal fase responsável pela resistência de aderência entre a argamassa e o bloco cerâmico é a etringita. Esta aderência se dá pelo intertravamento dos cristais e pela penetração dos mesmos no interior dos poros do substrato. Foram visualizados cristais de etringita formados no interior dos poros do substrato até uma profundidade de até 500µm. Esta penetração foi confirmada através da observação das variações nas concentrações de elementos químicos, em função da profundidade, utilizando-se a técnica de FRX. Não se observou nenhuma relação direta entre a profundidade de penetração do cálcio e a resistência de aderência. A profundidade e a quantidade de penetração do cálcio estão relacionadas à quantidade de aglomerantes, ou seja, cimento e/ou cal. Foram verificadas diferentes morfologias dos produtos de hidratação dos aglomerantes. Os cristais observados na interface são mais bem formados (euédricos) e maiores do que no restante da matriz e possuem uma orientação preferencial perpendicular à superfície do bloco. Nesta região a presença de etringita é preponderante e, em menores concentrações, o CSH (silicato de cálcio hidratado) e a calcita. Este fato se deve à maior mobilidade dos íons sulfato, alumínio e cálcio durante a hidratação do cimento e à proximidade ao substrato poroso, que proporciona a sucção do fluido contendo estes íons para o seu interior. Observou-se também diferentes morfologias para os cristais de etringita nos diversos traços utilizados, causada provavelmente pela variação do teor de cal e de aglomerante na argamassa. A variação da cal também influenciou na extensão de aderência e no adensamento da argamassa, afetando desta maneira os valores de resistência e a forma de ruptura. Nos ensaios de arrancamento foi observado que após a ruptura da argamassa, uma fina camada permanece aderida ao tijolo, visível a olho nu, denotando que a ruptura ocorreu pela falta de coesão da argamassa próxima à interface, afastada cerca de 200 µm. Este comportamento deixa a entender que o rompimento não ocorreu na faixa rica em etringita, e sim no interior da camada de argamassa, bem próxima à superfície de contato.
