Porém o peso próprio do concreto convencional é considerado a sua maior desvantagem. Com isso abre-se campo para um material que apesar de ser conhecido pelos romanos, era pouco utilizado, o concreto com agregados leves. Muitas pesquisas surgem e em aproximadamente duas décadas aparece o concreto autoadensável e mais recentemente o concreto leve autoadensável. Este trabalho propõe o estudo deste material ainda pouco explorado o concreto leve autoadensável. Para isso são produzidos concretos com argila expandida em duas granulometrias diferentes: uma graúda em substituição total ao agregado graúdo de massa normal e uma miúda em substituição parcial ao agregado miúdo. São elaboradas três famílias de traços de concreto com consumos diferentes de cimento, 320, 360 e 440 kg/m³ de concreto, e realizados ensaios no estado fresco (anel J, funil V e caixa L) e endurecido (resistências à compressão e à tração, determinação do módulo de elasticidade, absorção e densidade). Os concretos leves foram classificados como auto adensáveis e apresentaram bons resultados quanto ao fator de eficiência e resistência sendo possível estabelecer equações de correlação para seu módulo de elasticidade. Para os ensaios de densidade observaram-se concretos leves com massas mínimas de até 1550 kg/m³ e resistências à compressão superiores aos valores estipulados pela norma NBR NM 35 para as densidades apresentadas em todas as misturas / Abstract: With the discovery of admixtures and mineral additions many different types of concrete emerged over the last decades. But the own weight of conventional concrete is considered their biggest disadvantage. With this opens up the field for a material that despite being known to the Romans, it was little used, the concrete with lightweight aggregates. Much research and come in about two decades appears the self compacting concrete and more recently the lightweight concrete self compacting. This work proposes the study of this material still little explored concrete lightweight self compacting. For this are produced concrete with expanded clay in two different particle sizes: one coarse in total replacement of coarse aggregate of normal mass and a fine partially substituting fine aggregate. Are designed three families of concrete mixtures with different cement consumption, 320, 360 and 440 kg / m³ of concrete, and the tests carried out in the fresh state (ring J, V funnel and L box) and hardened (resistance to compression and traction , determining the modulus of elasticity, absorption, and density). The concretes were classified as self compacting and showed good results as to efficiency and resistance factor being possible to establish a correlation equations for its modulus of elasticity. For the density tests were observed concretes with minimum masses of up to 1550 kg / m³ and compressive strengths greater than those stipulated by NBR NM 35 standard for the densities presented in all mixtures / Mestrado / Tecnologia e Inovação / Mestre em Tecnologia

Agrégation et extraction des connaissances dans les réseaux inter-véhicules / Aggregation and extraction of knowledge in inter-vehicle networks

Zekri, Dorsaf 17 January 2013 (has links)
Les travaux réalisés dans cette thèse traitent de la gestion des données dans les réseaux inter-véhiculaires (VANETs). Ces derniers sont constitués d’un ensemble d’objets mobiles qui communiquent entre eux à l’aide de réseaux sans fil de type IEEE 802.11, Bluetooth, ou Ultra Wide Band (UWB). Avec de tels mécanismes de communication, un véhicule peut recevoir des informations de ses voisins proches ou d’autres plus distants, grâce aux techniques de multi-sauts qui exploitent dans ce cas des objets intermédiaires comme relais. De nombreuses informations peuvent être échangées dans le contexte des «VANETs», notamment pour alerter les conducteurs lorsqu’un événement survient (accident, freinage d’urgence, véhicule quittant une place de stationnement et souhaitant en informer les autres, etc.). Au fur et à mesure de leurs déplacements, les véhicules sont ensuite « contaminés » par les informations transmises par d’autres. Dans ce travail, nous voulons exploiter les données de manière sensiblement différente par rapport aux travaux existants. Ces derniers visent en effet à utiliser les données échangées pour produire des alertes aux conducteurs. Une fois ces données utilisées, elles deviennent obsolètes et sont détruites. Dans ce travail, nous cherchons à générer dynamiquement à partir des données collectées par les véhicules au cours de leur trajet, un résumé (ou agrégat) qui fourni des informations aux conducteurs, y compris lorsqu’aucun véhicule communicant ne se trouve pas à proximité. Pour ce faire, nous proposons tout d’abord une structure d’agrégation spatio-temporelle permettant à un véhicule de résumer l’ensemble des événements observés. Ensuite, nous définissons un protocole d’échange des résumés entre véhicules sans l’intermédiaire d’une infrastructure, permettant à un véhicule d’améliorer sa base de connaissances locale par échange avec ses voisins. Enfin, nous définissons nos stratégies d’exploitation de résumé afin d’aider le conducteur dans la prise de décision. Nous avons validé l’ensemble de nos propositions en utilisant le simulateur « VESPA » en l’étendant pour prendre en compte la notion de résumés. Les résultats de simulation montrent que notre approche permet effectivement d’aider les conducteurs à prendre de bonnes décisions, sans avoir besoin de recourir à une infrastructure centralisatrice / The works in this thesis focus on data management in inter-vehicular networks (VANETs). These networks consist of a set of moving objects that communicate with wireless networks IEEE 802.11, Bluetooth, or Ultra Wide Band (UWB). With such communication mechanisms, a vehicle may receive information from its close neighbors or other more remote, thanks to multi-jump techniques that operate in this case intermediate objects as relays. A lot of information can be exchanged in the context of « VANETs », especially to alert drivers when an event occurs (accident, emergency braking, vehicle leaving a parking place and want to inform others, etc.). In their move vehicles are then « contaminated » by the information provided by others. In this work, we use the data substantially different from the existing work. These are, in fact, use the data exchanged to produce alerts drivers. Once these data are used, they become obsolete and are destroyed. In this work, we seek to generate dynamically from data collected by vehicles in their path, a summary (or aggregate) which provides information to drivers, including when no communicating vehicle is nearby. To do this, we first propose a spatio-temporal aggregation structure enabling a vehicle to summarize all the observed events. Next, we define a protocol for exchanging summaries between vehicles without the mediation of an infrastructure, allowing a vehicle to improve its local knowledge base by exchange with its neighbors. Finally, we define our operating strategies of the summary to assist the driver in making decision. We validated all of our proposals using the «VESPA» simulator by extending it to take into account the concept of summaries. Simulation results show that our approach can effectively help drivers make good decisions without the need to use a centralized infrastructure

No. of bitstreams: 1 Antonio Luiz Ferrador Filho.pdf: 5915578 bytes, checksum: 551fba401297a5d3da42829909edc17d (MD5) Previous issue date: 2017-02-23 / The building sector is one of the largest consumers of energy in global terms, hence the importance of search for energy efficiency in this Field. According to the buildings life cycle, it is in the operational phase in which the highest energy consumption occurs. This research aimed to identify opportunities for energy efficiency improvements in a public, existing and operational Tribunal de Justiça de São Paulo building. The applied method was the case study. Data were collected in unstructured interviews and technical visits at the site, as well as related documentation examination. The data were analyzed by the PROCEL-Edifica prescriptive method, obtaining energy classification for the three characteristics of the building: the envelope got the label C, the illumination got label C and the conditioning of air got label B. The building general classification obtained was label C. The implications of this work for practice are in indicating potential improvements in the building's facilities to increase energy efficiency and in the analysis of potential and limitations for the study replication in other buildings. Some of the potential improvements identified were: change of fluorescent lamps to LEDs, change in the rooms lighting circuit, use of polarized films in the building’s glass, improvement in the vertical and horizontal shading of tower façades by using elements that reduce the direct incidence of sunlight. A basic investment payback period analysis for some improvements was conducted, as a examples to a action priorities definition. The method used can serve as a basis of a systematic to be replicated in other TJ/SP buildings. This study can contribute to the enhancement of the TJ/SP Sustainable Logistics Plan, in its line of buildings energy efficiency. In general, the prescriptive method accepted by PROCEL-Edifica criteria is indicated for this study’s replication in other buildings of the TJ/SP, due to the agility to change parameters theoretically and obtain results that may guide the introduction of energetic efficiency improvement measures. However, the “envelope” dimension evaluation has a more complex replication and possibly will require trained technicians participation when analyzing other buildings. / O setor de edificações é um dos maiores consumidores de energia em termos globais, daí a importância da busca da eficiência energética neste campo. Levando em conta o ciclo de vida das construções, é na sua fase operacional em que ocorre o maior consumo de energia. Esta pesquisa buscou identificar oportunidades de melhorias em eficiência energética em um edifício do Tribunal de Justiça de São Paulo, público, existente e operacional. O método aplicado foi o estudo de caso. Os dados foram coletados em entrevistas não estruturadas e visitas técnicas no local, além do exame de documentação relacionada. Foi feita a análise dos dados pelo método prescritivo do PROCEL-Edifica, obtendo classificação energética para as três características do prédio: a envoltória foi caracterizada com a etiqueta C, a iluminação a etiqueta C e o condicionamento de ar a etiqueta B. A classificação geral do prédio obtida foi etiqueta C. As implicações deste trabalho para a prática estão na indicação de potenciais melhorias nas instalações do prédio para aumento da eficiência energética e na análise de potencial e limitações para a replicação do estudo em outros prédios. Algumas das potenciais melhorias identificadas foram: mudança de lâmpadas fluorescentes para LED, alteração no circuito de iluminação de salas, uso de filmes polarizados nos vidros, melhoria no sombreamento vertical e horizontal das fachadas da torre pela utilização de elementos que diminuam a incidência direta da luz solar, como brises. Uma análise básica de tempo de retorno de investimento para algumas melhorias foi feito, demonstrando possível priorização de ações. O método usado pode servir como base de uma sistemática a ser replicada em outros edifícios do TJ/SP. Esse estudo visa contribuir para o aperfeiçoamento do Plano de Logística Sustentável do TJ/SP, na sua linha de eficiência energética de edifícios. No geral o método prescritivo aceito pelos critérios do PROCEL-Edifica é indicado para replicação do estudo em outros prédios do TJ/SP, devido a agilidade para alterar parâmetros teoricamente e obter resultados que orientem a introdução de medidas de melhorias da eficiência energética. No entanto, a avaliação da dimensão "envoltória" tem uma replicação mais complexa e possivelmente exigirá a participação de técnicos treinados quando da análise de outros edifícios.
