Fundação de Apoio a Pesquisa e à Inovação Tecnológica do Estado de Sergipe - FAPITEC/SE / Não informado. / O desenvolvimento de software de Processamento de Linguagem Natural (PLN) é altamente dependente da boa qualidade do que chamamos de corpus Linguístico. Um corpus é uma coleção de textos processáveis pelo computador, mas produzidos dentro de um ambiente comunicativo natural. Essa dependência advém do fato de que a maior parte do trabalho realizado com PLN hoje em dia está relacionado ao uso de técnicas de Aprendizado de Máquina para criação de modelos de linguagem. Para sistemas que permitem correção automática e previsão de palavras e sentenças, por exemplo, modelos linguísticos são gerados a partir de um corpus de texto a partir de transcrições usando N-Gram. Infelizmente, corpora linguísticos em português do Brasil não são abundantes e sua confecção não é uma tarefa trivial. Um caminho para a confecção de corpus linguísticos em Português é a confecção de CrawlersWeb. Focused Crawlers, em particular, têm o propósito de coletar páginas da Web que sejam relevantes a um tópico ou interesse específico do usuário. FocusedCrawlers existentes ainda não atendem completamente a necessidades específicas e toda potencialidade de um sistema de PLN. Esta dissertação de mestrado se propõe a contribuir com o Estado da Arte ao propor uma ferramenta para a confecção automática de corpora bem representativos ao objetivo do usuário que possam ser balanceados em respeito a fatores tais como tipo de coleta, domínio, língua, formalidade do discurso e rotulação do texto. A ferramenta permite ainda que etapas de pós-processamento sejam realizadas, como por exemplo limpeza do corpus, construção de um modelo de linguagem e de um modelo de entidades nomeadas. Dois corpora foram criados em duas formas de coleta distintas: por dados da Web (corpus Vaza- Barris) ou por dados do Twitter (corpus Poxim). O corpus VazaBarris possui 86 milhões de palavras e o Poxim possui 3 milhões de palavras. Estes corpora foram avaliados por meio da criação de modelo de linguagem e comparação com dois outros corpora em Português. Os resultados mostram que Poxim alcançou o melhor valor de perplexidade. Poxim também traz maior contribuição quando interpolado com algum outro corpus. Além dos corpora, foi criado um método de coleta automática para streaming de dados, utilizando o algoritmo de Relevance Feedback. Segundo os resultados, utilizar Relevance Feedback para a coleta dos dados melhorou o valor de perplexidade com o corpus coletado inicialmente. Um terceiro corpus foi criado para rotulação de Entidades Nomeadas, o Paramopama. O Paramopama é uma versão estendida PtBR do corpus WikiNer, com inclusão das entidades Pessoa, Localização, Organização e Tempo. Os resultados mostram que o Paramopama apresentou melhoria para as métricas de Precisão, Cobertura e Medida-F na comparação com outros três corpora do Estado da Arte.

Projetada como uma interface de controle entre switches e controladores, o protocolo pode ser visto como um conjunto de instruções para programar a lógica de encaminhamento em comutadores da rede. A primeira versão do OpenFlow atraiu a atenção de pesquisadores da indústria e universidades interessados nos potenciais benefícios prometidos por RDS. Rápidamente surgiram ferramentas para experimentação em OpenFlow 1.0, incluindo comutadores, controladores e software para testes e emulação. Após o início da padronização do protocolo pela OpenNetworkFoundation, o protocolo OpenFlow evoluiu rapidamente dando origem à novas especificações. As novas funcionalidades aumentaram as possibilidades de experimentos, gerando entusiasmo. Porém, o desenvolvimento das ferramentas de experimen- tação não acompanharam o mesmo rítmo do protocolo. Para preencher essa lacuna, nosso projeto desenvolveu um comutador em software com suporte a OpenFlow 1.3. Guiado pelo objetivo de ser simples e básicos requisitos de desempenho, a proposta da ferramenta é ser uma opção, fácil e funcional para desenvolvedores de aplicações RDS buscando utilizar as novas funcionalidades do OpenFlow 1.3. Em suma, o software desenvolvido nesse projeto foi o primeiro comutador OpenFlow 1.3 do mundo. Lançado como projeto de código aberto, possibilitou a pesquisadores de todo o mundo a prototipagem e demonstração de soluções não possíveis anteriormente / Abstract: OpenFlow is the most prominent technology to enable Software Defined Networking (SDN). Designed as a control interface between switches and controllers, the protocol can be considered an instruction set to program the network forwarding logic. The first OpenFlow version attracted attention from both the industry and academy researchers interested in SDN promised benefits. Quickly, a toolset for OpenFlow 1.0 was available, which included switches, controllers, test and emulation software. When the protocol standardization process started by the Open Network Foundation, OpenFlow evolved fast and new specifications emerged in the last years. New features empowered the protocol and created enthusiasm; however projects of experimentation tools did not followed the OpenFlow fast pace. This work addresses one of these gaps, implementing an experimenter friendly OpenFlow 1.3 software switch. Driven by simplicity and basic performance requirements, the tool purpose is to be a functional and easy option for SDN developers that want to take advantage of the benefits brought by more recent OpenFlow versions. Overall, this project resulted in the open source release of the first OpenFlow 1.3 switch, allowing researchers from all around the globe to prototype and demonstrate solutions not possible until this work.

O programa GenSeed, descrito previamente pelo nosso grupo, implementa um método de montagem progressiva dirigida por semente, o qual permite reconstruir sequências de DNA para montagem alvo-específicas partindo-se de sequências semente curtas de DNA ou proteína. Esse programa pode ser aplicado para a reconstrução de fragmentos genômicos, extracromossômicos e cDNAs, mas não é adequado para a reconstrução de sequências utilizando sementes e bases de dados derivadas de amostras heterólogas. O presente trabalho teve como objetivo o desenvolvimento do GenSeed-HMM, uma versão do GenSeed, capaz de utilizar HMMs de perfis como sementes para a reconstrução de sequências específicas, e de processar dados gerados pelas novas plataformas de sequenciamento, incluindo leituras curtas. Este trabalho relata a implementação do programa GenSeed-HMM, e sua validação utilizando dados reais de diferentes plataformas de sequenciamento, originados de procariotos, eucariotos, bem como de amostras metagenômicas. / The program GenSeed, previously described by our group, implements a seed-driven progressive assembly method for target-specific assembly of DNA sequences, starting from short DNA or protein seed sequences. The program can be applied for the reconstruction of genomic fragments, extrachromosomal genomes, and cDNAs, but is not adequate for sequence reconstruction using seed sequences and databases derived from heterologous samples. The present work aimed at developing GenSeed-HMM, a new version of GenSeed program that can use profile HMMs as seeds for the reconstruction of specific sequences, and incorporates the ability to work with data generated by the new sequencing platforms, including short reads. This work reports the implementation of GenSeed-HMM program and its validation using real life data produced by different next-generation sequencing platforms, and originated from prokaryotic, eukaryotic and metagenomic samples.

<p>Imaging-based analysis of developmental processes are crucial to understand the mechanisms controlling plant and animal development. In vertebrate embryos such as the zebrafish embryo, nuclei segmentation plays an important role to detect and quantify nuclei over space and time. However, limitations of the image quality and segmentation methods may affect the segmentation performance. In plant including studies on Arabidopsis epidermis growth, cellular shape change dictates organ size control and growth behavior, and quantitative image analysis of dynamics cell patterning is needed to link the cause and effect between cells and organs. Here we provide a series of new quantitative biological imaging methods a series of new quantitative biological imaging methods and tools including wavelet-based segmentation method in zebrafish embryo development studies and convex hull approach for quantitative shape analyses of lobed plant cells.</p> <p> </p> <p>Identification of individual cells in tissues, organs, and in various developing systems is a well-studied problem because it is an essential part of objectively analyzing quantitative images in numerous biological contexts. In this paper we present a size dependent wavelet-based segmentation method that provides robust segmentation without any preprocessing, filtering or fine-tuning steps, and is robust to the signal-to-noise ratio (SNR). The program separates overlapping nuclei, identifies cell cycle states and minimizes intensity attenuation in object identification. The wavelet-based methods presented herein achieves robust segmentation results with respect to True Positive rate, Precision, and segmentation accuracy compared with other commonly used methods. We applied the segmentation program to Zebrafish embryonic development IN TOTO quantification and developed an automatic interactive imaging analysis platform named WaveletSEG, that integrates nuclei segmentation, image registration, and nuclei shape analysis. A set of additional functions we developed include a 3D ground truth annotation tool, a synthetic image generator, a segmented training datasets export tool, and data visualization interfaces are also incorporated in WaveletSEG for additional data analysis and data validation. </p> <p> </p> <p>In addition to our work in Zebrafish, we developed image analysis tools for quantitative studies of cell-to-organ in plants. Given the importance of the epidermis and this particular cell type for leaf expansion, there is a strong need to understand how pavement cells morph from a simple polyhedral shape into highly lobed and interdigitated cells. Currently, it is still unclear how and when patterns of lobing are initiated in pavement cells, and one major technological bottleneck to address the problem is the lack of a robust and objective methodology to identify and track lobing events during the transition from simple cell geometry to lobed cells. We develop a convex-hull-based algorithm termed LobeFinder to identify lobes, quantify geometric properties, and create a useful graphical output for further analysis. The algorithm is validated against manually curated cell images of pavement cells of widely varying sizes and shapes. The ability to objectively count and detect new lobe initiation events provides an improved quantitative framework to analyze mutant phenotypes, detect symmetry-breaking events in time-lapse image data, and quantify the time-dependent correlation between cell shape change and intracellular factors that may play a role in the morphogenesis process.</p>

The dissertation deals with solution of beam and frame structure considering material nonlinearity. The finite elements method (FEM) was used as calculation method. The objective of the dissertation was to develop and test finite beam element considering material nonlinearity. A detailed analysis of the problem provided a group of formulations of beam element. Part of the dissertation´s results has been, in several forms, implemented in commercial software. Beam element focused on solution of stress over solid cross sections is introduced in the theoretical part. In terms of topology it is a classical prismatic beam element with two nodes. Six degrees of freedom for translations and rotations are defined in each node plus 7-th degree of freedom for warping function from torsion. Load form axial force, bending moments, primary torsion, shear forces and eventually bimoment for secondary torsion were considered in cross section. Several variants of formulations were created according to inclusion of loading components into material nonlinearity and according to numeric integration method. Inclusion of geometric nonlinearity and fire resistance calculation are discussed in the dissertation. The above mentioned formulations were tested on prototypes as described in the application part which also provides information on the general procedure, architecture and technologies used for implementation of knowledge from the theoretical part into commercial FEM software. The dissertation shows implementation of plasticity for shell, solutions of cross section characteristics and stress on cross section, implementation of beam element with material nonlinearity and module for fire resistance of column. The above mentioned implementations of theoretical conclusions are the main outputs of the dissertation. These implementations are available in thousands of installations throughout Europe where being used at projection of significant constructions.
