Today, the average computer user has undoubtedly encountered the PDF format while handling electronic documents. Due to its wide-spread popularity and feature richness, PDF documents are commonly utilized by attackers in order to infect systems with malware. This thesis will present The Extendable Guideline for Analysing Malicious PDF Documents. This work will establish the foundation of the guideline and populate it with a part of the analysis process. The guideline relies on earlier published material in the topic. It is a practical guideline that is followed by the use of a flowchart and can be utilized by an analyst in order to determine if a PDF document is malicious or not. It provides technical background information, suitable analysis techniques, and tools. The guideline structure was developed by using sequential thinking in combination with the divide and conquer paradigm. The thesis will also elucidate commonly applied techniques that are used by malicious PDF authors in order to infect systems, evade detection, and distribute their malicious documents. A commonly utilized function in PDF documents are the JavaScript feature. There are a wide range of other features that are targeted by malicious PDF authors, but they are more rarely encountered. PDF documents are often distributed by attackers by sending them as an attachment in an email, or storing the document on a web server.

Le développement technologique a ses avantages et ses inconvénients. Nous pouvons facilement partager et télécharger du contenu numérique en utilisant l’Internet. En outre, les utilisateurs malveillants peuvent aussi modifier, dupliquer et diffuser illégalement tout type d'informations, comme des images et des documents. Par conséquent, nous devons protéger ces contenus et arrêter les pirates. Le but de cette thèse est de protéger les documents PDF et les images en utilisant la technique de tatouage numérique Spread Transform Dither Modulation (STDM), tout en tenant compte des exigences principales de transparence, de robustesse et de sécurité.La méthode de tatouage STDM a un bon niveau de transparence et de robustesse contre les attaques de bruit. La clé principale dans cette méthode de tatouage est le vecteur de projection qui vise à diffuser le message sur un ensemble d'éléments. Cependant, un tel vecteur clé peut être estimée par des utilisateurs non autorisés en utilisant les techniques de séparation BSS (Blind Source Separation). Dans notre première contribution, nous présentons notre méthode de tatouage proposé CAR-STDM (Component Analysis Resistant-STDM), qui garantit la sécurité tout en préservant la transparence et la robustesse contre les attaques de bruit.STDM est également affecté par l'attaque FGA (Fixed Gain Attack). Dans la deuxième contribution, nous présentons notre méthode de tatouage proposé N-STDM qui résiste l'attaque FGA et améliore la robustesse contre l'attaque Additive White Gaussian Noise (AWGN), l'attaque de compression JPEG, et diversité d'attaques de filtrage et géométriques. Les expérimentations ont été menées sur des documents PDF et des images dans le domaine spatial et le domaine fréquentiel.Récemment, l’Apprentissage Profond et les Réseaux de Neurones atteints du développement et d'amélioration notable, en particulier dans le traitement d'image, la segmentation et la classification. Des modèles tels que CNN (Convolutional Neural Network) sont utilisés pour la dé-bruitage des images. CNN a une performance adéquate de dé-bruitage, et il pourrait être nocif pour les images tatouées. Dans la troisième contribution, nous présentons l'effet du FCNN (Fully Convolutional Neural Network), comme une attaque de dé-bruitage, sur les images tatouées. Les méthodes de tatouage STDM et SS (Spread Spectrum) sont utilisés durant les expérimentations pour intégrer les messages dans les images en appliquant plusieurs scénarios. Cette évaluation montre qu'un tel type d'attaque de dé-bruitage préserve la qualité de l'image tout en brisant la robustesse des méthodes de tatouages évaluésTechnological development has its pros and cons. Nowadays, we can easily share, download, and upload digital content using the Internet. Also, malicious users can illegally change, duplicate, and distribute any kind of information, such as images and documents. Therefore, we should protect such contents and arrest the perpetrator. The goal of this thesis is to protect PDF documents and images using the Spread Transform Dither Modulation (STDM), as a digital watermarking technique, while taking into consideration the main requirements of transparency, robustness, and security. STDM watermarking scheme achieved a good level of transparency and robustness against noise attacks. The key to this scheme is the projection vector that aims to spreads the embedded message over a set of cover elements. However, such a key vector can be estimated by unauthorized users using the Blind Source Separation (BSS) techniques. In our first contribution, we present our proposed CAR-STDM (Component Analysis Resistant-STDM) watermarking scheme, which guarantees security while preserving the transparency and robustness against noise attacks. STDM is also affected by the Fixed Gain Attack (FGA). In the second contribution, we present our proposed N-STDM watermarking scheme that resists the FGA attack and enhances the robustness against the Additive White Gaussian Noise (AWGN) attack, JPEG compression attack, and variety of filtering and geometric attacks. Experimentations have been conducted distinctly on PDF documents and images in the spatial domain and frequency domain. Recently, Deep Learning and Neural Networks achieved noticeable development and improvement, especially in image processing, segmentation, and classification. Diverse models such as Convolutional Neural Network (CNN) are exploited for modeling image priors for denoising. CNN has a suitable denoising performance, and it could be harmful to watermarked images. In the third contribution, we present the effect of a Fully Convolutional Neural Network (FCNN), as a denoising attack, on watermarked images. STDM and Spread Spectrum (SS) are used as watermarking schemes to embed the watermarks in the images using several scenarios. This evaluation shows that such type of denoising attack preserves the image quality while breaking the robustness of all evaluated watermarked schemes

Full textAbstract:
Digital search engine, taking a search request from user and then returning a result responded to the request to the user, is indispensable for modern humans who are used to surfing the Internet. On the other hand, the digital document PDF is accepted by more and more people and becomes widely used in this day and age due to the convenience and effectiveness. It follows that, the traditional library has already started to be replaced by the digital one. Combining these two factors, a document based search engine that is able to query a digital document database with an input file is urgently needed. This thesis is a software development that aims to design and implement a prototype of such search engine, and propose latent optimization methods for Loredge. This research can be mainly divided into two categories: Prototype Development and Optimization Analysis. It involves an analytical research on sample documents provided by Loredge and a multi-perspective performance analysis. The prototype contains reading, preprocessing and similarity measurement. The reading part reads in a PDF file by using an imported Java library Apache PDFBox. The preprocessing processes the in-reading document and generates document fingerprint. The similarity measurement is the final stage that measures the similarity between the input fingerprint with all the document fingerprints in the database. The optimization analysis is to balance resource consumptions involving response time, accuracy rate and memory consumption. According to the performance analysis, the shorter the document fingerprint is, the better performance the search program presents. Moreover, a permanent feature database and a similarity based filtration mechanism are proposed to further optimize the program. This project has laid a solid foundation for further study in the document based search engine by providing a feasible prototype and enough relevant experimental data. This study figures out that the following study should mainly focuses on improving the effectiveness of the database access, which involves data entry labeling and search algorithm optimization.Digital sökmotor, som tar en sökfråga från användaren och sedan returnerar ett resultat som svarar på den begäran tillbaka till användaren, är oumbärligt för moderna människor som brukar surfa på Internet. Å andra sidan, det digitala dokumentets format PDF accepteras av fler och fler människor, och det används i stor utsträckning i denna tidsålder på grund av bekvämlighet och effektivitet. Det följer att det traditionella biblioteket redan har börjat bytas ut av det digitala biblioteket. När dessa två faktorer kombineras, framgår det att det brådskande behövs en dokumentbaserad sökmotor, som har förmåga att fråga en digital databas om en viss fil. Den här uppsatsen är en mjukvaruutveckling som syftar till att designa och implementera en prototyp av en sådan sökmotor, och föreslå relevant optimeringsmetod för Loredge. Den här undersökningen kan huvudsakligen delas in i två kategorier, prototyputveckling och optimeringsanalys. Arbeten involverar en analytisk forskning om exempeldokument som kommer från Loredge och en prestandaanalys utifrån flera perspektiv. Prototypen innehåller läsning, förbehandling och likhetsmätning. Läsningsdelen läser in en PDF-fil med hjälp av en importerad Java bibliotek, Apache PDFBox. Förbehandlingsdelen bearbetar det inlästa dokumentet och genererar ett dokumentfingeravtryck. Likhetsmätningen är det sista steget, som mäter likheten mellan det inlästa fingeravtrycket och fingeravtryck av alla dokument i Loredge databas. Målet med optimeringsanalysen är att balansera resursförbrukningen, som involverar responstid, noggrannhet och minnesförbrukning. Ju kortare ett dokuments fingeravtryck är, desto bättre prestanda visar sökprogram enligt resultat av prestandaanalysen. Dessutom föreslås en permanent databas med fingeravtryck, och en likhetsbaserad filtreringsmekanism för att ytterligare optimera sökprogrammet. Det här projektet har lagt en solid grund för vidare studier om dokumentbaserad sökmotorn, genom att tillhandahålla en genomförbar prototyp och tillräckligt relevanta experimentella data. Den här studie visar att kommande forskning bör huvudsakligen inriktas på att förbättra effektivitet i databasåtkomsten, vilken innefattar data märkning och optimering av sökalgoritm.

Full textAbstract:
Mestrado em Engenharia de Computadores e TelemáticaO aumento acelerado da literatura biomédica levou ao desenvolvimento de vários esforços para extrair e armazenar, de forma estruturada, a informação relativa aos conceitos e relações presentes nesses textos, oferecendo aos investigadores e clínicos um acesso rápido e fácil à informação. No entanto, este processo de "curadoria de conhecimento" é uma tarefa extremamente exaustiva, sendo cada vez mais comum o uso de ferramentas de anotação automática, fazendo uso de técnicas de mineração de texto. Apesar de já existirem sistemas de anotação bastante completos e que apresentam um alto desempenho, estes não são largamente usados pela comunidade biomédica, principalmente por serem complexos e apresentarem limitações ao nível de usabilidade. Por outro lado, o PDF tornou-se nos últimos anos num dos formatos mais populares para publicar e partilhar documentos visto poder ser apresentado exatamente da mesma maneira independentemente do sistema ou plataforma em que é acedido. A maioria das ferramentas de anotação foram principalmente desenhadas para extrair informação de texto livre, contudo hoje em dia uma grande parte da literatura biomédica é publicada e distribuída em PDF, e portanto a extração de informação de documentos PDF deve ser um ponto de foco para a comunidade de mineração de texto biomédico. O objetivo do trabalho descrito nesta dissertação foi a extensão da framework Neji, permitindo o processamento de documentos em formato PDF, e a integração dessas funcionalidades na plataforma Egas, permitindo que um utilizador possa visualizar e anotar, simultaneamente, o artigo original no formato PDF e o texto extraído deste. Os sistemas desenvolvidos apresentam bons resultados de desempenho, tanto em termos de velocidade de processamento como de representação da informação, o que também contribui para uma melhor experiência de utilizador. Além disso, apresentam várias vantagens para a comunidade de mineração de texto e curadores, permitindo a anotação direta de artigos no formato PDF e simplificando o uso e configuração destes sistemas de anotação por parte de investigadores.
The accelerated increase of the biomedical literature has led to various efforts to extract and store, in a structured way, the information related with the concepts and relations presented in those texts, providing to investigators and researchers a fast and easy access to knowledge. However, this process of “knowledge curation” is an extremely exhaustive task, being more and more common demanding the application of automatic annotation tools, that make use of text mining techniques. Even thought complete annotation systems already exist and produce high performance results, they are not widely used by the biomedical community, mainly because of their complexity and also due to some limitations in usability. On the other hand, the PDF has become in the last years one of the most popular formats for publishing and sharing documents because of it can be displayed exactly in the same way independently of the system or platform where it is accessed. The majority of annotation tools were mainly designed to extract information from raw text, although a big part of the biomedical literature is published and distributed in PDF, and thus the information extraction from PDF documents should be a focus point for the biomedical text mining community. The objective of the work described in this document is the extension of Neji framework, allowing the processing of documents in PDF format, and the integration of these features in Egas platform, allowing a user to simultaneously visualize the original article in PDF format and its extracted text. The improved and developed systems present good performing results, both in terms of processing speed and representation of the information, contributing also for a better user experience. Besides that, they present several advantages for the biomedical community, allowing the direct annotation of PDF articles and simplifying the use and configuration of these annotation systems by researchers.

Full textAbstract:
Le chiffrement d'une communication sur un canal quelconque pose un problème de taille. Un émetteur doit en effet transmettre au récepteur une information lui permettant de décoder une communication chiffrée. Le canal d'information n'étant souvent pas physiquement sécurisé, cette information préliminaire doit être transmise sans que les interlocuteurs n'aient à se soucier qu'un autre acteur puisse intercepter cette information.
Différents algorithmes ont été développés afin de rendre possible cet échange préliminaire. Parmi les algorithmes communéments utilisés, la cryptographie à courbe elliptique permet de maximiser la sécurité d'une communication avec un minimum d'échange préliminaire d'information.
La cryptographie à courbe elliptique repose sur la multiplication d'un point sur cette courbe par un scalaire. Cette opération est relativement lourde au niveau logiciel. Le développement d'un co-processeur spécialisé pour cette opération devient alors pertinent.
Ce mémoire résume le développement de pareil co-processeur. Ce dernier a été développé sur FPGA en minimisant les ressources logiques utilisées tout en maximisant la fréquence d'horloge opérationnelle. De plus, le nombre d'opérations sur la courbe elliptique a été minimisé en représentant l'entier multipliant le point sur la courbe elliptique sous sa forme numérique ω-NAF.
Ce mémoire propose également une façon inédite pour générer aléatoirement un entier sous sa forme ω-NAF en minimisant les ressources logiques nécessaires pour pareille opération.The encryption of a communication on a given channel may appear hazardous. An interlocutor must transmit to another one enough information allowing both interlocutors to encrypt or decrypt the communication. Since the communication channel is visible to potentially malicious actors, this preliminary information must be exchanged without worrying about others intercepting it. Several algorithms were developed making that exchange possible. Among the most commonly used algorithms, elliptic curve cryptography provides the highest strength per bit. Elliptic curve cryptography is based on the multiplication of a point on this curve by a scalar. This operation is relatively complex when implemented in software. The use of a specialized co-processor becomes an interesting approach to perform this operation. This thesis describes the development of such a co-processor. It has been developed targeting a FPGA, minimizing the use of logical resources while maximizing the operating frequency. Moreover, the number of operations on the elliptic curve have been minimized by representing the scalar multiplying the point of the elliptic curve in its ω-NAF form. A method randomly generating an integer in its ω-NAF representation is also proposed. This method can be implemented in hardware using a minimum of logical resources.

The effects of this 5 E Learning Cycle on 8th grade Earth and Space Science students were studied in a small public middle school. Additionally, this project looked at the effects of the 5 E Learning Cycle on teacher instruction. Instructional lessons were planned and presented using the 5 E Learning Cycle while pre-, mid.-, and post- formal and summative assessments were collected to show its effects on students and the teacher. Through these assessments, science learning of the state standards increased, while the ability to understand and apply inquiry got better at first, but then showed a decrease in getting better. The teacher's role in the classroom changed, as did the way she planned and presented each lesson and guided the class. Promoting inquiry in the classroom increased.

Full textAbstract:
La première partie de la thèse est consacrée à de nouvelles méthodes de synthèse. Nous avons évalué une nouvelle méthode d’activation des thioglycans. Le réactif IPy2BF4 s’est avéré comme étant une des meilleures sources de I+ (iodonium) dans un nombre de réactions cyclisantes. Ce réactif est disponible commercialement mais n’a jamais été évalué dans le contexte de réactions de glycosylations malgré de nombreux précédant par rapport à l’utilisation d’électrophile pour activer les thioglycans. Dans la seconde partie, les travaux ce sont centrés sur les oligomères de carbohydrates fonctionnalisés. Basé sur l’expérience de notre groupe dans le domaine des peptides d’acides nucléiques (PNAs), nous voulions étudier la conjugaison de carbohydrates avec des PNAs. A cette fin, nous avons étudié trois approches, couplage hydrazone glycal, des couplages de cycloaddition (click), et couplages chimiosélectifs entre un chloroacetamide et glycosyl thiol. Ces deux dernières approches ce sont avérées robustes donnant des conjugués PNA-glycan avec de très bon rendements. Afin d’émuler la fonction glycans complexes par autoassemblage de fragments de glycan-PNAs sur des brins ADN, nous avons évalué l’affinité de plus de 30 complexes pour l’anticorps 2G12. Suite à ces résultats, nous avons synthétisé une chimiothèque de glycans encodée par des PNAs afin d’optimiser l’affinité pour le DC-SIGN, un récepteur de cellules dendritiques impliqué dans les réponses immunitaires. Nous avons aussi étendu l’utilité des ces conjugués glycan-PNA en démontrant qu’il peuvent être autoassemblé dans un format micrarray pour cribler des protéines reconnaissant les carbohydrates telles que les lectinsThe first part of my thesis deals with the Novel Synthetic Methods. IPy2BF4 is a stable, solid and commercial available reagent. It was initially developed by Professor Barluenga. IPy2BF4 reagent is a powerful source for iodonium ion. It has never been explored in carbohydrate glycosylation. We were interested investigate the IPy2BF4 reagent for the thioflycoside glycosylation. The second part of my thesis deals with the Functional Carbohydrate Oligomers. Based on the experience of our group in Peptide nucleic acids (PNAs), we wanted to study the assembly of carbohydrates and PNAs conjugation. To discover the simple method for carbohydrate-PNAs conjugation is important for the carbohydrate protein study. We chose three approaches for the conjugation study, hydrazone formation, cycloaddition coupling and glycosyl thiol. After the preparation of complex functional glycans, we further evaluated the binding affinity with 30 complex glycans for 2G12 antibody. Based on the above results, we synthesized the azidosugar for the PNAs conjugation to further optimize the binding affinity with DC-SIGN. We also investigated the glycan fragment for the combinatorial self-assembly into microarrays and carbohydrate protein binding affinity study with specific lectins

Nous utilisons le logiciel open source ≪ BALLView ≫ pour créer nos propres modèles de feuillets β. La première approche utilise la description des feuillets β présente dans les fichiers issus de la ≪ Protein Data Bank ≫, la banque de données mondiale de structures protéiques, pour calculer une interpolation bidimensionnelle basée sur les splines de Catmull-Rom. La seconde approche utilise des carreaux de Bézier, construits a partir des résultats issus d'un algorithme d'attribution des structures secondaires des protéines, dont les feuillets β font partie. Ces approches sont les premières à représenter les feuillets β dans leur ensemble. Les modèles classiques ne représentent que les brins β. Pour visualiser leur orientation nous plaquons cette information par le biais de textures. Cela nous amène à considérer nos surfaces comme de nouveaux medias sur lesquels nous pouvons dépeindre des données supplémentaires par l'intermédiaire de méthodes de coloration (≪ Hydrophobic Cluster Analysis ≫, ≪ Molecular Hydrophobicity Potential ≫…). Nos modèles sont utilisables sur l'ensemble des fichiers au format PDB, en statique, mais également sur des fichiers de simulation de dynamique moléculaire. Nous pouvons alors constater l'évolution des feuillets β, leurs déformations, l'apparition de trous, d'invaginations ou de déchirures. Ces constatations nous amènent à baptiser nos modèles SheHeRASADe pour ≪ Sheets Helper for RepresentAtion of SurfAce Descriptors ≫. Nous nous intéressons, entre autres, à l'application de ces modèles sur les divers repliements protéiques des feuillets β repertoriés dans la classification CATH, ainsi qu'aux fibres amyloides, impliquées dans de nombreuses pathologiesThe aim of this work consists in the representation of common structural motifs of proteins: the β sheets. The classical visualization modes are not satisfying, considering that they don't represent the whole β sheets. We propose innovative models materializing those structures using surfaces. We use the open source software "BALLView" to create our own β sheet models. The first one uses the β sheets description stored in files from the Protein Data Bank, the worldwide data bank of proteic structures, to compute a bidimensionnal interpolated surface based on Catmull-Rom splines. The second one uses Bezier patches defined from β sheets produced by a secondary structure prediction algorithm. Those models are the first ones to fully represent β sheets. Previous methods only represent β strands. In order to visualize their orientation, we map these important data to our surfaces by using textures. It leads us to consider our surfaces as a new medium on which we can depict additional information using coloring methods (Hydrophobic Cluster Analysis, Molecular Hydrophobicity Potential. . . ). Our models are available for any PDB formatted file, in both static and dynamic ways, using molecular dynamics simulations. We can observe the evolution of β sheets, deformations, holes appearances, invaginations or splits. Those observations lead us to call our models SheHeRASADe for "Sheets Helper for RepresentAtion of SurfAce Descriptors". We apply those models to the different proteic folds of β sheets listed in the CATH classification, and on amyloid fibrils involved in many diseases

O presente trabalho trata de um estudo de caso que é um breve estudo sobre novos tipos de assentamentos e a sustentabilidade como elemento fundamental em sua constituição. Sua localização é na região do Vale do Ribeira, no município de Apiaí-SP. Teve como objetivo geral contribuir para o processo de sistematização de um novo modelo de assentamento na perspectiva da adoção da Agroecologia como matriz tecnológica e como objetivos específicos: levantar os elementos para constituição do Assentamento - Prof. Luiz D. Macedo; criar subsídios para Projeto de Desenvolvimento Sustentável-Prof. Luiz Macedo durante sua implantação de tal forma a sugerir balizamentos para novos assentamentos e fazer associação dos objetivos anteriores com o debate em torno da conservação da Mata Atlântica na região do Vale do Ribeira. Foi desenvolvido a partir de uma metodologia que tem dados secundários e dados primários, sendo os secundários obtidos a partir de pesquisa bibliográfica e os primários optou-se por utilizar a metodologia de pesquisa participante. E teve como considerações finais, que analisando em linhas gerais o PDS Prof. Luiz D. Macedo, pode se verificar que este cumpre os fundamentos básicos previstos na portaria do PDS, apontando para novos tipos de assentamentos de Reforma Agrária, se opondo ao paradigma da revolução verde, buscando a sustentabilidade e podendo ser considerado um assentamento que caminha rumo à Agroecologia. Pela análise realizada evidencia-se que passa por dificuldades organizativas e estruturais e também por dificuldades de garantir a reprodução social das famílias, porém pode ser um referencial para implantação de outros PDS e principalmente outros localizados na região do Vale do Ribeira. Este trabalho, a ser apresentado e discutido no assentamento, representa um ponto de chegada, mas também devemos pensá-lo como partida para novas investigações: Para que o mesmo possa avançar novas trilhas devem ser desenvolvidos por trabalhos acadêmicos futuros, entre as quais: Retorno na comunidade, fazer a organização e análise dos dados coletados: problemas e contradições na visão da comunidade e na perspectiva dos educadores - seleção de falas e fenômenos significativos (descritivos, analíticos e propositivos). Escolha de temas geradores considerando a perspectiva dos assentados. Redução temática: rede temática, tema / contratema / questão geradora geral. Seleção de conhecimentos sistematizados a partir das relações presentes na rede temática. Negociação entre os coordenadores do assentamento e a equipe de ATER, os conhecimentos e as relações da rede que cada um pretende trabalhar. Preparação de programações interdisciplinares. Que conteúdos dão conta das falas geradoras? Quais as temáticas fundamentais? Preparação de atividades dialógicas para a atuação na comunidade: cursos, seminários, visitas à outras experiências, pauta de reivindicações etc. Realização das atividades preparadas, sempre submetendo-as a avaliação da comunidade, cujos encaminhamentos podem ser alterados no desenvolvimento das ações, resultando em novas pesquisas e planos de trabalho.
This paper deals with a case study that is a brief study of new types of settlements and sustainability as a key element in its constitution. Its location is in the Vale do Ribeira, the city of Apiaí-SP. Had a general objective to contribute to the process of systematization of a new settlement model in view of the adoption of agroecology as technological matrix and specific objectives: to raise the elements to constitute the settlement - Prof. Luiz D. Macedo; create subsidies for Sustainable Development Project-Prof. Luiz Macedo during their deployment in such a way that suggests beacon for new settlements and to associate the previous goals with the debate on the conservation of Atlantic Forest in the Vale do Ribeira. It was developed using a methodology that has secondary data and primary data, being secondary data from the literature research and the primary we chose to use the methodology of participatory research. And had the final considerations, which broadly analyzing the PDS Prof. Luiz D. Macedo, can verify that it complies the basic fundamentals in the ordinance provided for the PDS, pointing to new types of settlements of agrarian reform, opposing the paradigm of the green revolution, looking for sustainability and could be considered a settlement that moves toward to Agroecology. For the analysis shows that undergoes structural and organizational difficulties and also problems of ensuring the social reproduction of families, but may be a reference for implementation of other PDS and other mainly located in the Vale do Ribeira. This work, to be presented and discussed at the settlement represents a point of arrival, but we must also think of it as starting point for further research: So that it can advance new trails should be developed for future academic work, including: Return in the community, make the organization and data analysis: problems and contradictions in the community's vision and perspective of educators - selection of speeches and significant phenomena (descriptive, analytical and purposeful). Choosing subjects were generated considering the perspective of the settlers. Reduction theme: thematic network, theme / countertheme / generator general question. Selection of systematic knowledge of the relations present in the thematic network. Negotiating between the coordenators of the settlement and ATER team, knowledge and relationships that each network they want to work. Preparation of interdisciplinary programs. Realize that the speech content generators? What are the key themes? Preparatory dialogic activities in the community: classes, seminars, visits to other experiences, list of demands, etc. o Carrying out the activities prepared, always putting them to a community assessment, whose referrals can be changed in the development of actions resulting in new research and work plans.

This master's thesis seeks to contribute to the automation of production lines, and proposes a methodology for the formal verification of flexible manufacturing models by the Petri-PDL tool. The Petri-PDL framework is based on a multimodal logic associated with a scheme defined for the problem with the Petri nets to specify and model sequential problems demonstrating in logical proofs the correctness of properties inferred by the model. This formal treatment is adapted for the treatment of flexible sequential processes, since these models are used in many other applications with Petri nets. They will be considered models of flexible production system found in the systematic review to evaluate the efficiency of its model and its adaptation to this formal refinement.

O conceito Petri-PDL baseia-se em uma lógica multimodal associada ao esquema definido para o problema com as redes de Petri para especificar e modelar problemas sequenciais demonstrando em provas lógicas a corretude de propriedades inferidas pelo modelo. Este tratamento formal será adaptado para o tratamento de processos sequenciais flexíveis, uma vez que estes modelos são usados em muitas outras aplicações com redes de Petri. Serão considerados modelos de sistema de produção flexível encontrados na revisão sistemática para avaliar a eficiência de seu modelo e sua adaptação a este refinamento formal.

Full textAbstract:
The dissertation describes Pd0-catalyzed formal 1,3-diaza-Claisen rearrangement and the design and development of cationic 1,3-diaza-Claisen rearrangement.
Our previous work has shown that isocyanates react with azanorbornenes and azabicyclo[2.2.2]octenes under thermal conditions to afford zwitterionic intermediates that undergo a thermal 1,3-diaza-Claisen rearrangement to give both ureas and isoureas. However, some azanorbornenes and azabicyclooctenes failed to rearrange or proceeded in low yields. To address these challenging substrates for the thermal 1,3-diaza-Claisen rearrangement, we have developed a Pd0-catalyzed formal 1,3-diaza-Claisen rearrangement. Interestingly, under Pd0-catalyzed condition, both isocyanates with electron-withdrawing groups and isocyanates without electron-withdrawing groups react with azanorbornenes and azabicyclo[2.2.2]octenes to provide ureas as the only products in high yields. More importantly, the reactions that failed under thermal conditions were all successful under Pd0-catalysis. In addition to azanorbornenes and azabicyclo[2.2.2]octenes, other ring systems were also investigated. Pd0 catalysis has broadened the scope of tertiary allylic amines that react with isocyanates to afford 1,3-diaza-Claisen rearrangement products.
In the presence of p-TsCl and NEt3, allylaminopropyl benzyl ureas were initially dehydrated to form protonated carbodiimides whose presence was confirmed by the infrared absorption frequency at 2100 cm-1 which is the characteristic band of -N=C=N-; then the in situ generated protonated carbodiimides were poised for further cationic 1,3-diaza-Claisen rearrangement to afford synthetically challenging guanidines. The effect of acid on the rearrangement was ascertained by the fact that no rearrangement product was observed by simply heating free base carbodiimide 3.10 in benzene at reflux. Other dehydration reagents, such as Tf2O, Ts2O, MsCl were also investigated, and none of them provide satisfactory results. A selection of allyamino benzyl ureas with different tether length, substituents, or in varied ring systems, were synthesized to explore the scope of this methodology. This methodology works best at allylaminopropyl benzyl ureas, and the substituents on the benzyl group does not seem to affect the reaction rate in a significant way.

Previous issue date: 2007-03-21This work follows the line of research University, Teaching and Education of Teachers . It analyzes the implications of implementing the implantation of public policy in Minas Gerais with the Program of Professional Development of Educators (PDP) and the configuration of the curriculum in Schools-Reference under the jurisdiction of the Regional Superintendence of Education in Po?os de Caldes, Minas Gerais. This policy considers teachers as constructors and re-constructors during the course of their education and profession with the objective of developing activities with pedagogical accompaniment and support for implanting new curricular proposals conjecturing the Common Basic Curriculum (CBC) In the light of this scenario the investigation tried to respond to the following question: What are the advances and obstacles present in the implantation of the Program for the Professional Development of Educators (PDP) being implanted by the State of Minas Gerais? It utilized bibliographical and documentary research; data for analysis was obtained at the end of 2006 by means of semi-structured interviews. Seven professors participated in these: four Coordinators of the Group of Professional Development and three Representatives of the Area. The study revealed that the professors attribute great value to the program for professional development and improvement of performance in SEEMGking teaching quality, and that the encounters held in the schools favored the practice of dialogic reflection. However, they questioned the type of presentation and the time of the implementation of the program, as well as the bureaucracy, the availability of funds and the assessment that do not correspond to facilitating the program s proposal. They revealed beliefs, worries and conflicts that ought to be considered by the creators of the program for bringing into effect the intended changes in the Minas Gerais educational system, keeping in mind the investment and confidence deposited by the State Department of Education in this modality of improving the quality of service.

As redes metalorgânicas (ou MOF, do inglês Metal-Organic Frameworks) pertencem à classe dos polímeros de coordenação (ou CP, do inglês coordination polymers) e exibem características como porosidade e cristalinidade. Em particular, as MOF bidimensionais têm despertado o interesse no desenvolvimento de uma nova geração de dispositivos ópticos e eletrônicos. A capacidade de formação de filmes finos de algumas dessas MOF as tornam materiais mais atraentes. A MOF bidimensional estudada neste trabalho foi a rede {[Zn(2,5-pdc)(H2O)2].H2O}n (2,5-pdc = 2,5-piridinodicarboxilato), ZnPDC2D. A MOF 2D foi sintetizada e caracterizada por diferentes técnicas experimentais e também foi estudada por simulação computacional. O modelo do ZnPDC2D foi otimizado por dois métodos (PBE e PBE-D2), os quais descreveram bem os parâmetros estruturais. A partir do modelo do ZnPDC2D, foi elaborada uma proposta para o processo de desidratação e assim, sugerindo a formação de três novas fases (d1-ZnPDC2D, d2-ZnPDC2D e d3-ZnPDC2D). A temperatura em que o ZnPDC2D sofre amorfização foi determinada através da medida de difração de raios X com aumento de temperatura in situ e pôdese inferir que a fase amorfa sofre uma transformação reversível após ser exposta ao ambiente. A termodinâmica da primeira etapa da desidratação mostra que o funcional PBE é mais adequado para descrever a espontaneidade da reação. Esperase obter as estruturas por meio de análises de difração de raios X por policritais e refinamento pelo método de Rietveld. O trabalho também reporta a simulação da energia de formação do monofilme pelos métodos PBE e PBE-D2. As análises de propriedades eletrônicas para todas as estruturas citadas foram executadas e discutidas conforme os processos e mudanças envolvidas.
Metal-organic frameworks (MOFs) belong to the class of coordination polymers (CPs) and exhibit properties such as porosity and crystallinity. In particular, twodimensional MOFs have attracted interest in the development of a new generation of optical and electronic devices. The possibility of thin film formation of some of these MOFs makes them more attractive materials. The twodimensional MOF studied in this work was the network {[Zn(2,5-pdc)(H2O)2].H2O}n (2,5-pdc = 2,5-pyridinedicarboxylate), ZnPDC2D. The MOF 2D was synthesized and characterized by different experimental techniques and was also studied by computer simulation. Two optimized ZnPDC2D structures were obtained by distinct methods (PBE and PBE-D2) with a good description of their parameters. The structure obtained from the simulation of the dehydration process suggest the formation of three new phases (d1-ZnPDC2D, d2-ZnPDC2D and d3-ZnPDC2D). The temperature at which ZnPDC2D undergoes amorphization was determined by Xray podwer diffraction measurement with in situ temperature rise and it could be inferred that the amorphous phase undergoes a reversible transformation after being exposed to the environment. The thermodynamics of the first stage of dehydration shows that the PBE functional is adequate to describe the spontaneity of the reaction. The structures are expected to be obtained by Xray podwer diffraction analysis and refinement by the Rietveld method. Thise work also reports the simulation of the monofilm by the PBE and PBE-D2 methods. The analyses of electronic properties for all th cited structures were performed and discussed according to the processes and changes involved.

This thesis deals with the question of electronic security systems. In the forepart are described electronic security system components such as keyboards, detectors, alarm devices etc. Various methods of security or de-security of properties, trespassing and other events detection methods, and ways of alarm calling are described there too. The next part of the master’s thesis focuses on the construction of an alarm system which is designed for security of a common-size flat with one entry. The system manages to control up to four movement detectors. The operation of the system is handled by a 16 button keyboard, and easy orientation is provided thanks to a liquid crystal display. The alarm is signaled by an indoor alert siren, however, other alarm announcing devices with an input matched for the log. 0 or log. 1 reception can be connected too. The system contains communication equipment (mobile phone) which signals alarm at a distance to the three telephone numbers. User can use a distance control by text message to unlock system or to determine its status. The system is controlled by the microcontroller AVR ATmega16, the product of Atmel company. A brief description of all components of the electronic alarm system is included in this work.
