Computer security and privacy are becoming extremely important nowadays. The task of protecting computer systems from malicious attacks and potential subsequent catastrophic losses is, however, challenged by the ever increasing complexity and size of modern hardware and software design. We propose several methods to improve computer security and privacy from architectural point of view. They provide strong protection as well as performance efficiency. In our first approach, we propose a new dynamic information flow method to protect systems from popular software attacks such as buffer overflow and format string attacks. In our second approach, we propose to deploy encryption schemes to protect the privacy of an emerging non-volatile main memory technology - phase change memory (PCM). The negative impact of the encryption schemes on PCM lifetime is evaluated and new methods including a new encryption counter scheme and an efficient error correct code (ECC) management are proposed to improve PCM lifetime. In our third approach, we deconstruct two previously proposed secure cache designs against software data-cache-based side channel attacks and demonstrate their weaknesses. We propose three hardware-software integrated approaches as secure protections against those data cache attacks. Also we propose to apply them to protect instruction caches from similar threats. Furthermore, we propose a simple change to the update policy of Branch Target Buffer (BTB) to defend against BTB attacks. Our experiments show that our proposed schemes are both security effective and performance efficient.

Due to the lack of literature available on the subject, basing on studies of the instrumental approach to teach foreign languages, especially English, the following objectives are established: to reflect on conceptualizations underpinning the approach to the teaching of languages for specific purposes; to identify and discuss guiding principles for a proposed teaching of Portuguese for specific purposes; to discuss the relevance of the Needs Analysis as a basis for the design of Portuguese courses for specific purposes; to reflect on the formation of the Portuguese teacher for specific purposes, identifying key requirements for teaching using this approach; to discuss the relevance (i) of working with textual genres related to the area of study of students, (ii) of teaching of reading strategies, (iii) of teaching of writing in procedural perspective; to propose alternatives to work with reading and production of text under the Academic Leveling in Portuguese Language for Pedagogy course, from the data of an Needs Analysis. Based on studies of instrumental approach to language teaching, including discussions about analysis of needs and the role of the teacher, an analysis is performed on the course design, considering the content selection and the work with genres, reading and production of texts. Basing on data obtained by applying an Needs Analysis, the course design of Academic Leveling in Portuguese for Pedagogy students of an Institution of Higher Education in São Paulo is proposed, with examples of suggested work writing procedural and reading strategies. The results indicate that a proposed course of Academic Leveling in Portuguese that prioritizes student needs in regards to the use of language in situations of interaction, from genres belonging to academic and/or (future) sphere of action of the students seemed to be relevant to provide the improvement of linguistic competence and, therefore, the inclusion of these students in Higher Education / Este trabalho, que se situa na linha de pesquisa sobre Leitura, Escrita e Ensino de Língua Portuguesa, trata do ensino de português para fins específicos e configura-se como pesquisa qualitativa e exploratória de investigação bibliográfica e empírica. Em virtude da pouca literatura disponível sobre o tema, partindo dos estudos da abordagem instrumental para o ensino de línguas estrangeiras, especialmente do inglês, os seguintes objetivos são estabelecidos: refletir sobre conceitualizações que sustentam a abordagem do ensino de línguas para fins específicos; identificar e discutir princípios norteadores para uma proposta de ensino de português para fins específicos; discutir a relevância da Análise de Necessidades como base para o desenho de cursos de português para fins específicos; refletir sobre a formação do professor de português para fins específicos, identificando requisitos fundamentais para a prática de ensino nessa abordagem; discutir a relevância (i) do trabalho com gêneros textuais relacionados à área de atuação dos alunos, (ii) do ensino de estratégias de leitura, (iii) do ensino da escrita na perspectiva processual; propor alternativas para o trabalho com leitura e produção de texto no âmbito do Nivelamento Acadêmico em Língua Portuguesa do curso de Pedagogia, a partir dos resultados de uma Análise de Necessidades.

Les chapes autonivelantes sont souvent composées de ciment alumineux et de sulfate de calcium pour assurer une prise rapide. Le ciment alumineux est généralement à base de monocalcium aluminate (CA). Récemment, un nouveau ciment alumineux riche en mayénite (C12A7) a été conçu pour optimiser l’application des chapes par l’augmentation de la quantité d’ettringite formée. Le développement de l’hydratation au jeune âge (pendant les premières 24 heures) de ce type de produit est pourtant très peu connu. L’objectif principal de cette étude est d’évaluer l’interaction entre l’hydratation au jeune âge et le séchage naturel à travers un modèle de couplage. Ce modèle est appliqué à l’étude d’une pâte pure ettringitique composée de ciment riche en C12A7 et de plâtre alpha. Tout d’abord, un modèle cinétique d’hydratation, initialement développé en système dilué, a été proposé pour étudier l’hydratation d’une pâte pure ettringitique en condition endogène. Il permet de décrire l’évolution en fonction du temps de la porosité, de la teneur en eau, des quantités de phases (réactifs et hydrates). Un modèle de distribution de rayon de pores a été aussi proposé. Ce modèle permet d’obtenir la courbe de pression capillaire au jeune âge nécessaire pour la modélisation des transferts hydriques. Ensuite, une modélisation complète des transferts hydriques a été présentée. Elle a montré que l’hypothèse d’une pression de gaz constante conduit à une surestimation de perte de masse pour des matériaux à faible perméabilité. Pourtant, pour le cas des ciments alumineux, cette hypothèse peut être retenue pour simplifier le couplage avec le modèle cinétique d’hydratation. Enfin, une modélisation des couplages entre l’hydratation et la dessiccation a été développée. L’originalité de ce modèle porte sur l’intégration de la courbe isotherme issue du modèle de distribution poreuse dans la modélisation des transferts hydriques via une fonction Matlab. Le modèle a été capable de reproduire la cinétique de perte de masse d’un échantillon de pâte pure ettringite réactive soumis au séchage précoce. La nécessité de la prise en compte de l’évolution de température a été mise en évidence. De plus, le modèle a prévu un arrêt précoce de l’hydratation à la surface séchante après 10 heures d’hydratation. L’effet de la dessiccation atteint une profondeur de 5 mm sur un échantillon de 3 cm d’épaisseur. / Self-leveling flooring compounds (SLC) are often composed of calcium aluminate cements (CAC) and calcium sulfate to ensure rapid setting. The mineral composition of calcium aluminate cements is usually designed around monocalcium aluminate (CA). Recently, a new cement with the main compound of mayenite (C12A7) has been designed to optimize the application of SLC by increasing the amount of ettringite in the hydration product. However, there is a lack of knowledge related to early-age hydration (during the first 24 hours) of this type of product. The main objective of this study is to evaluate the interaction between early-age hydration and natural drying through a coupling model. This model is applied to the study of an ettringite binder composed of cement rich in C12A7 and plaster First, a kinetic model of hydration, initially developed in a diluted system, has been proposed to study the hydration of an ettringite paste under endogenous conditions. It allows to describe the evolution as a function of time of the porosity, the water content, and the quantities of phases (reactants and hydrates). A model of pore size distribution has also been proposed. This model allows us to obtain the capillary pressure curve at early-age, which is necessary for the modeling of moisture transport. Then, a complete modeling of water transfers was presented. It has shown that the assumption of constant gas pressure leads to an overestimation of mass loss for weakly permeable materials. However, for the case of CAC, this hypothesis can be retained to simplify the coupling with the kinetic model of hydration. Finally, a modeling of the coupling between hydration and desiccation has been developed. The originality of this model concerns the integration of the isothermal curve resulting from the pore size distribution model in the modeling of water transfers via a Matlab function. The model was able to reproduce the kinetics of mass loss of a sample of ettringite binder subjected to early drying. The role of temperature was also elucidated. In addition, the model predicted an early stop of hydration on the drying surface after 10 hours of hydration. The effect of desiccation reaches a depth of 5 mm on a sample with a thickness of 3 cm.

Tem como objetivo aprimorar a qualificação dos profissionais que cada vez mais vêm sendo requisitados para trabalhos técnicos, seja na esfera nacional ou internacional. Com o intuito de haver um maior entendimento do estudo, foi feito um histórico do desenvolvimento da Educação Profissionalizante desde o tempo do Brasil colônia até os dias de hoje, destacando algumas das principais leis que normalizam o processo educacional, validando o caráter do trabalho. Durante o desenvolvimento deste projeto houve preocupação em sinalizar que o ensino técnico profissionalizante noturno Pós-Médio sofre várias interferências do Ensino Médio, onde ocorrem lacunas importantes em relação à Física, fundamentais ao aprendizado de matérias técnicas. Além disso, também é apresentada uma análise dos conteúdos de Física em que é necessário suprir deficiências e carências localizadas. Leva-se em conta o nível socioeconômico dos alunos e suas necessidades, por se tratarem de pessoas que trabalham e estudam ao mesmo tempo, procurando melhorar sua formação profissional. Dessa maneira, propõe-se o currículo de um Curso de Nivelamento em Física, de caráter semipresencial e com a utilização de email e do aplicativo WhatsApp, com os conhecimentos necessários para auxiliar nas matérias técnicas. Com isso, espera-se diminuir a repetência e evasão escolar nos cursos técnicos noturnos Pós-Médio da ETEHL, com perspectivas de que o Nivelamento seja estendido para outras unidades escolares da rede estadual de educação técnica. / In the present work it is presented a proposal of a Leveling course of Physics for the professional technical education in Post Middle at the State Technical School Henrique Lage (STSHL). It aims at improving the qualification of professionals who increasingly are being required to work either in the national and international sphere. Towards a better understanding of the study, it was made a historical development of professional education since the time of colonial Brazil until the present day, highlighting some of main laws that normalize the education process, validating the character of the work. During the development of this project there was concern in signalizing that the professional education in Post Middle night courses undergoes several High School interferences, where important disruptions occur related with Physics, which are fundamental to the learning of technical disciplines. Besides it is presented an analysis of the Physics contents in which the deficiencies and shortcomings are located. It is taken into account the social economic level of the students and their needs, since they are people who work and study at the same time, trying to improve their professional education. In this way, it is proposed a curriculum of a Leveling Physics course, with a partly in person character, using email and the applicative WhatsApp and exploring the topics required to assist them in the technical disciplines. Doing so, it is expected decreasing repetition rates and truancy in the night Post Middle courses at STSHL, with perspectives that the Leveling Course can be extended to other school unities of the professional educational state system.
