Title: Correspondence Problem in Geometric Morphometrics Tasks Author: Václav Krajíček Department / Institute: Department of Software and Computer Science Education Supervisor of the doctoral thesis: RNDr. Josef Pelikán Supervisor's e-mail address: pepca@cgg.mff.cuni.cz Abstract: Shape analysis in physical anthropology, biomedicine, and related disci- plines is mostly done using landmarks or by measuring distances. New techno- logical advancements allow the digitization of object's appearance in the form of triangular meshes or volume images. These digital images are especially beneficial in the cases when landmarks cannot be used to effectively describe the shape. In order to statistically analyze shape in a sample of observations, which are represented by these modalities, correspondence has to be found. Registration is a crucial tool in mapping the shape representations into a common space where correspondence is found by nearest neighbor principle in the case of triangular meshes or by overlaps in the case of volume images. B- spline based non-rigid registration is chosen because of its versatility, relative speed and ability to handle both meshes and volume images. Experiments were also performed with other alternatives - Thin-plate splines and Coherent point drift. The algorithm was modified to handle...

Advancement of micro-electro-mechanics and wireless communication have proliferated the deployment of large-scale wireless sensor networks. Due to cost, size and power constraints, at most a few sensor nodes can be equipped with a global positioning system; such nodes (whose positions can be accurately determined) are referred to as anchors. However, one can deter-mine the distance between two nearby sensors using some form of local communication. The problem of computing the positions of the non-anchor nodes from the inter-sensor distances and anchor positions is referred as sensor network localization (SNL). In this dissertation, our aim is to develop an accurate, efficient, and scalable localization algorithm, which can operate both in the presence and absence of anchors. It has been demon-strated in the literature that divide-and-conquer approaches can be used to localize large net-works without compromising the localization accuracy. The core idea with such approaches is to partition the network into overlapping subnetworks, localize each subnetwork using the available distances (and anchor positions), and finally register the subnetworks in a single coordinate system. In this regard, the contributions of this dissertation are as follows: We study the global registration problem and formulate a necessary “rigidity” condition for uniquely recovering the global sensor locations. In particular, we present a method for efficiently testing rigidity, and a heuristic for augmenting the partitioned network to enforce rigidity. We present a mechanism for partitioning the network into smaller subnetworks using cliques. Each clique is efficiently localized using multidimensional scaling. Finally, we use a recently proposed semidefinite program (SDP) to register the localized subnetworks. We develop a scalable ADMM solver for the SDP in question. We present simulation results on random and structured networks to demonstrate the pro-posed methods perform better than state-of-the-art methods in terms of run-time, accuracy, and scalability.

This work describes a method based on three stages for reconstructing a model from a given set of scanned meshes obtained from 3D scanners. Meshes scanned from different scanner s view points have their representation in local coordinate systems. Therefore, for final model reconstruction, an alignment of the meshes is required. The most popular algorithm for cloud data registration is the ICP algorithm. However, ICP requires an initial estimate of mesh alignment, which is, many times, done manually. To automate this process, this work uses a surface representation called spin-images to identify overlap areas between the meshes and to estimate their alignment. After this initial registration, the alignment is refined by the ICP algorithm, and finally the model is reconstructed using a method called VRIP. / Fundação de Amparo a Pesquisa do Estado de Alagoas / Este trabalho descreve um método baseado em três etapas para reconstrução de modelos a partir de malhas capturadas de scanners 3D. Malhas obtidas a partir de diferentes pontos de visão de um scanner têm sua representação em sistemas de coordenadas local. Portanto, para a reconstrução final do modelo, é necessário realizar um alinhamento dessas malhas, ou registro. O algoritmo mais famoso para realizar registro de nuvens de pontos é o algoritmo ICP. Porém, um dos requisitos desse algoritmo é uma estimativa inicial do alinhamento das malhas, que muitas vezes é feita manualmente. Para automatizar esse processo, este trabalho utiliza descritores spin-image para identificar regiões de sobreposição entre as malhas e estimar seus alinhamentos. Após este registro inicial, o alinhamento é refinado através do algoritmo ICP, e finalmente o modelo é reconstruído usando uma técnica chamada VRIP.

Its services are notably classified as sluggish, bureaucratic, with a low productivity level and a high incidence of mistakes. In periods of crisis, public administration must be the first to give good examples of balance and parsimony in its expenditures, or it could lead to the failure of the government, in general, causing damages to the population. To reach this goal, some corrective measures must be done, in different directions, by selecting the expenditures and fostering the maximum economy for the exchequer. This is only possible through the application of correct planning techniques, a still far way reality from the culture of our public organisms. One way to this change is the adoption of the Price Registration System, that in the Federal scope was already adopted by the Decree nº 3.931/01, and in the scope of the municipality of Manaus was ordered by the Decree nº 8.270/06. The present study verifies the influence of the use of the Price Registration System in purchases and contracts undertaken by the Local Secretariat of Construction, Basic Services and Housing, in the city of Manaus concerning the economy obtained when compared to other methods of tenders. / Há décadas a administração pública vem sendo rotulada de ineficiente, com grande desperdício de dinheiro público e baixa geração de resultados percebidos pela sociedade. Seus serviços são notoriamente classificados como morosos, burocráticos, com baixo grau de produtividade e alta incidência de erros. Nos momentos de crise, a administração pública deve ser a primeira a dar exemplos de equilíbrio e parcimônia nos seus gastos, sob pena de fracassar o governo, como um todo, causando prejuízo à população. Para atingir esse objetivo, há que se tomarem medidas saneadoras, em diversificadas direções, selecionando as despesas e procurando o máximo de economia para o erário. Isso só é possível mediante a aplicação das corretas técnicas de planejamento, uma realidade ainda distante da cultura de nossos órgãos públicos. Um dos caminhos para essa mudança é a adoção do Sistema de Registro de Preços que, no âmbito federal, já foi adotado pelo Decreto nº 3.931/01, e no âmbito do município de Manaus pelo Decreto nº 8.270/06. Esse estudo verifica a influência da utilização do Sistema de Registro de Preços nas compras e contratações realizadas pela Secretaria Municipal de Obras, Serviços Básicos e Habitação, na cidade de Manaus, no tocante relacionado à economia gerada em comparação às demais modalidades de licitação.

A pesquisa utilizou informações de variados sites (órgãos federais, associações, entidades de pesquisa, jornais agrícolas de grande circulação), bem como atas de reuniões, relatórios, planilhas e apresentações dos três órgãos federais. Os dados levantados indicaram uma tendência de aumento no tempo de registro de um novo ingrediente ativo. Esta pesquisa reforça a importância de uma discussão profunda sobre a eficiência na gestão pública e incentivo a inovação no Brasil. É possível notar que houve um grande avanço no segmento de produtos equivalentes, importantes para aumentar a oferta e competividade no setor, no entanto, percebe-se que o cenário atual pode não ser atrativo às empresas que focam em inovação devido a falta de previsibilidade no retorno de seus investimentos. / This research analyzes the behavior and performance of MAPA, ANVISA and IBAMA throughout the process of a new pesticide registration in order to evaluate how the regulation application affect the availability of new products to Brazilian farmers. The research based on information from a variety of websites (federal agencies, associations, entities and agricultural journals), as well as meetings minutes, reports, spreadsheets and presentations from the three federal agencies. The data collected indicated a trend to increase the approval timing of a new active ingredient. The data also indicated the importance of a deep discussion about efficiency in public management and incentive to innovation in Brazil. It is possible to notice that there has been a great advance in the segment of equivalent products, important to increase the supply and competitiveness to benefit growers, however, it is noteworthy that the current scenario may not be attractive to the companies that focus on innovation due to the lack of predictability in the return on investment.

Cabe pontuar a íntima relação que o PD tem com a etapa de solicitação de registro do medicamento junto à Agência Nacional de Vigilância Sanitária (ANVISA), visto que o mesmo subsidia a produção de lotes piloto, indispensáveis a esta solicitação, e diversas informações necessárias à estruturação documental.Entretanto, ainda que dotado de tais importâncias, em âmbito nacional, o setor regulado não dispõe de qualquer diretriz específica que oriente a condução do PD. Logo, o PD é norteado pelas exigências contidas nas regulamentações direcionadas à solicitação de registro. Esta dissertação objetiva avaliar, para o PD, a extensão da adesão das regulamentações sanitárias, emanadas pela ANVISA, que dispõem sobre a concessão de registro de medicamentos novos, genéricos e similares, atualmente vigentes, com os reques itos internacionais apresentados pela International Conference on Harmonization (ICH). Para tanto, é realizada uma comparação e contextualização por assunto (IFA, excipientes, formulação, processo produtivo, sistema de acondicionamento, atributos microbiológicos e compatibilidade com diluentes de reconstituição) das regulamentações mencionadas, com o Guia da ICH, especificamente, direcionado ao PD –Guia ICH Q8(R2). O princípio do Guia ICH Q8(R2), denominado Qualiy by Design(QbD), usado para a condução do PD, consiste na estruturação do mesmo segundo uma metodologia sistemática, científica, baseada na avaliação do risco, que parte da definição das características ideais de qualidade para o medicamento. Esta estruturação prevê o pleno conhecimento do medicamento, de seu processo de obtenção e controles. Este Guia também fomenta a construção do Design Space (DS), que se estabelece pela avaliação multivariada dos insumos e parâmetros do processo e a influência da variação sobre as características de qualidade do medicamento. Os resultados provenientes da comparação das regulamentações nacionais tratadas nesta dissertação com o Guia ICH Q8(R2), evidenciam que o QbD e a construção do DS não figuram nestas regulamentações. Assim , as divergências entre o Guia ICH Q8(R2) e as regulamentações superam em quantidade e qualidade as coincidências, evidenciando significativo distanciamento, no que tange o PD, entre as regulamentações nacionais de registro considerada se o pensamento internacional, representado pela ICH. / The process of developing a product (PD) is vital to the functionality of the active pharmaceutical ingredient (API), for determining the dosage form, formulation and production process, allowing their therapeutic function. It punctuate the close relationship that the PD has with the step of applying for registration of the drug by Agência Nacional de Vigilância Sanitária(ANVISA -Brazilian equivalent to FDA), since it subsidizes the production of pilot batches, which are essential to this request, and various information necessary for structuring documents. However, although endowed with such sums,the regulated sector has no specific guidelines to conduct of the PD. Therefore, the PD is guided by the requirements contained in regulations aimed at the registration request. This thesis aims to evaluate, for the PD, the extent of adherence of health regulations, issued by ANVISA, which provide for the granting of registration of new drugs, generic and similar currently in force, with the international requisites established by the International Conference on Harmonization (ICH). Therefore,it was done a comparison by subject (API, excipients, formulation, production process, packaging system, microbiological attributes and compatibility with diluents for reconstitution) of the regulations m entioned, with the ICH guide, specifically directed to PD -ICH Q8(R2). The principle of the ICH Q8(R2), called the Quality by Design (QbD), used to drive the PD, consists on scientific systematic methodology and risk assessment based on the definition of ideal drug quality characteristics. This structure provides the knowledge of medicine, of the production process and controls. This guide also encourages the construction of the Design Space (DS), which is established by multivariate assessment of inputs and process parameters and the influence of variation on the product quality.The results from the comparison of national regulations in this dissertation dealt with the Guide ICH Q8(R2), shown that the QBD and construction of the DS are not included in these regulations. Thus, the differences between the Guide ICH Q8(R2) and the regulations exceed in quantity and quality of the matches, showing a significant gap in relation to PD, between the national record and considered international thought, represented by the ICH.

L'évolution biologique des organismes peut être étudiée comme une succession de transformations morphologiques qui sont caractérisées par le changement de leur géométrie tridimensionnelle globale et locale. Dans ce contexte, il est nécessaire de développer des outils mathématiques et informatiques comparatifs de formes tridimensionnelles afin d'étudier ces transformations et de pouvoir les comparer avec les variabilités inter- et intra-espèces. Dans la chaîne de traitement des données tridimensionnelles (images 3D ou maillages 3D) employée en " paléoanthropologie virtuelle ", la méthode la plus souvent utilisée en analyse comparative est basée sur des points de repère (en général, anatomiques) dont les coordonnées sont analysées à l'aide d'outils mathématiques tels que la " morphométrie géométrique ". Plus récemment, une autre classe de méthodes a été proposée. Elle permet des comparaisons globales entre les surfaces complètes de structures anatomiques sans avoir besoin de définir des points de repère. On obtient ainsi une analyse statistique de la forme moyenne et de sa variabilité en tout point. Dans cette thèse, nous proposons d'étudier la chaîne d'analyse morphométrique des données 3D utilisées en paléoanthropologie, de la numérisation à l'exploitation des données par les chercheurs. Cette thèse présente des méthodes analytiques pour le traitement des données issues de la paléoanthropologie, depuis la numérisation des sites de fouilles jusqu'à l'acquisition et l'analyse des spécimens. Nous établissons des modèles numériques de terrain (analyses multidimensionnelles de données issues de différentes modalités d'acquisition telles que les scans laser et la photogrammétrie) qui permettent d'appréhender les vestiges dans leur contexte et nous proposons des analyses qui répondent à des problématiques qui sont spécifiques aux études en biologie. En particulier, nous apportons des outils d'analyse et de visualisation (cartographies 3D et analyses statistiques) pour des problématiques de déformation basées sur des recalages surfaciques. Nous proposons également une méthode d'analyse sur des données partielles afin de pouvoir exploiter l'ensemble des données disponibles dans les registres fossiles et modernes. Nos résultats mettent en évidence que les méthodes par recalage surfacique augmentent non seulement les possibilités de capter les formes et leurs variations, mais permettent également de travailler sur des formes globales et non uniquement sur certains points. Nous montrons notamment que ces méthodes permettent le développement d'outils qui sont bien adaptés pour les études en paléoanthropologie. / The biological evolution of organisms can be studied as a set of morphological transformations which are characterized by the modification of their global three- dimensional geometry and by some discrete traits. In this context, it is necessary to develop comparative mathematical and computational tools for the study of the inter- and intraspecific variation. Within the three-dimensional data processing workflow (3D images or 3D meshes) employed in " virtual paleoanthropology ", the method that is most commonly used in comparative analysis is based on landmarks (most often anatomical landmarks) from which coordinates are analyzed by using mathematical tools such as " geometric morphometrics ". More recently, other methods allowing global comparisons between three-dimensional reconstructions without landmarks have been proposed. They allow for example the statistical analysis of a global shape and its variability. We suggest to study the process for morphometric analysis of 3D data commonly used in paleoanthropology, from the digitization to the exploration of 3D data. This dissertation introduces analytical methods for the processing of data provided by paleoanthropological studies, from the digitization of the excavation sites to the acquisition and the analysis of specimens. We established digital ground models (multidimensional analyses of data from various modalities of acquisition such as laser scanner and photogrammetry) that contribute to a comprehensive understanding of fossil remains in their context and we proposed relevant analyses for resolving specific problems inherent to biological studies. In particular, we developed appropriate tools for analyses and viewing (3D mappings and statistical analyses) dedicated specifically to problems of deformation-based registrations. Additionally, we introduced a method for the analysis of partial data in order to use all the specimens available in the fossil and modern records. Besides opening up new possibilities of capturing shape variation, our results highlight that techniques based on surface registration provide a reliable methodological framework for working on global shapes without focusing on specific points. We reported in particular that these methods allow the development of tools which are particularly suitable for the paleoanthropological studies.

Fundação de Amparo à Pesquisa do Estado do Rio de Janeiro / A questão do patrimônio vem ganhando destaque nos últimos anos, sendo relacionada a temas e universos sociais variados e bastantes distintos. Este trabalho discute um dos aspectos mais recentes das políticas de patrimônio no Brasil, a política de inventário, registro e salvaguarda, instituída pelo Decreto 3.551. A tônica desta pesquisa foi refletir sobre a dinâmica do processo de transformação de determinadas expressões e práticas culturais em "bens patrimoniais", processo caracterizado aqui como a patrimonialização da cultura. O trabalho discute os impasses decorrentes da aplicação e operacionalização da política do patrimônio imaterial tendo como suporte o estudo do processo de inventário, registro e salvaguarda do jongo no Sudeste, realizado pelas equipes de pesquisa do Centro Nacional de Folclore e Cultura Popular CNFCP como parte do Projeto Celebrações e Saberes da Cultura Popular. / The issue of heritage has been gaining attention in recent years, related to diverse and quite distinct topics and social worlds. This paper discusses one of the most recent aspects of the heritage policies in Brazil, ie, the policy of inventory, registration and safeguard, established by Decree 3551, in 2000. The emphasis of this research was to reflect on the dynamics of the transformation of certain expressions and cultural practices in "patrimonial goods", a process characterized here as patrimonialization of culture. The work aims to discuss the impasse arising from the implementation and operationalization of the intangible heritage policy having as support the study of the inventory, registration and safeguard process of the jongo conducted by research teams of the National Center for Folklore and Popular Culture CNFCP, as part of Celebrations and Knowledge of Popular Culture Project.

O presente estudo teve, por objetivo, corrigir a magnitude dos óbitos registrados por câncer do colo do útero no Brasil, e analisar a magnitude da mortalidade por este câncer e sua associação com indicadores sociais, nos estados da região Nordeste, Brasil, no período compreendido entre 1996 a 2005. Para a correção do sub-registro, foram utilizados os fatores criados pelo Projeto Carga Global de Doença no Brasil-1998. Metodologia de redistribuição proporcional foi utilizada para redistribuir as categorias de diagnósticos desconhecidas, incompletas ou mal definidas de óbitos identificadas no sistema de informação sobre mortalidade, exceto os dados ausentes de idade, corrigidos através de imputação. As correções foram aplicadas para cada Unidade Federativa do pais, segundo sexo e grupo etário, e os resultados apresentados para o Brasil e cada grande região e suas respectivas áreas geográficas (capital, demais municípios das regiões metropolitanas e interior). Tendências temporais de mortalidade foram analisadas através de regressão linear simples para cada estado da região Nordeste. Índice de variação percentual foi utilizado para determinar a variabilidade da magnitude das taxas, antes e após a correção dos óbitos. Através de regressão linear, foram analisados o comportamento da correção, e as correlações entre os indicadores socioeconômicos e as taxas de mortalidade por câncer do colo de útero sem e com correção. Após as correções, as taxas de mortalidade por câncer do colo do útero no Brasil mostraram um acréscimo percentual 103,4%, com variação de 35%, para as capitais da região Sul, a 339%, para o interior da região Nordeste. Foram encontradas correlações positivas entre alguns indicadores socioeconômicos e taxas sem correção, e correlações negativa entre esses mesmos indicadores e taxas corrigidas. Com outros indicadores socioeconômicos, observou-se o inverso dessa situação. Os resultados da correção apresentaram consistência em termos geográficos e em relação aos achados da literatura, permitindo concluir que a metodologia proposta foi adequada para corrigir a magnitude das taxas de mortalidade por câncer do colo do útero no país. Se analises comparativas sobre as condições socioeconômicas e o comportamento deste câncer forem estimadas sem quaisquer conhecimentos acerca da cobertura e qualidade de registro dos óbitos, pode-se incorrer a conclusões equivocadas. Considerando a magnitude corrigida da mortalidade por câncer do colo do útero, podemos afirmar que o problema desta doença na região Nordeste e no país, e mais grave do que o observado nos informes oficiais. Contudo, os resultados apontam que os programas de controle e detecção precoce desenvolvidos no país já mostram resultados positivos. / This study aimed to correct the magnitude of registered deaths from cancer of the cervix in Brazil, and analyze the magnitude of mortality from this cancer and its association with social indicators in the states of the Northeast region, Brazil, in the period 1996 to 2005. For correction of under-registration, we used the factors created by the Global Burden of Disease Project in Brazil-1998. To redistribute the categories of diagnosis unknown, incomplete or poorly defined deaths, identified in the information system on mortality, was used the methodology of proportional redistribution, except the missing data of age, corrected by imputation. The corrections were applied to each state of the country, by sex and age group, and the results presented for Brazil and each major region and their respective geographical areas (capital, other cities and metropolitan areas of the interior). Temporal trends of mortality were analyzed using simple linear regression for each state of the region. Index percentage change was used to determine the variability of the magnitude of the rates before and after correction of the deaths. By linear regression, we analyzed the behavior of the correction and the correlations between the socio-economic indicators and mortality rates for cervical cancer with and without correction. After the correction, the mortality rates for cervical cancer in Brazil showed a percentile increment of 103.4%, with variation of 35% for capitals of South region, 339% for the interior of Northeastern region. Positive correlations between some socioeconomic indices and non -corrected rates, and negative association the same indices and fixed rates were evidenced. With others socioeconomic indices, the opposite behavior was observed. The results showed consistency in geographical terms and in relation to findings in the literature, allowing concluding that the proposed methodology was appropriate to correct the magnitude of the mortality rates for cervical cancer in the country. If comparative analysis on the socio-economic conditions and the behavior of this cancer are estimated without any knowledge about the quality and coverage of registration of deaths, wrong conclusions could be obtained. Considering the corrected magnitude of this disease we can affirm that cervical cancer in Northeastern region of Brazil is a problem bigger than the stated in the official reports. However, the results suggest that control and early detection programs developed in this country has shown positive results.

The aim of this master thesis is to analyze and evaluate the introduction of registration of sales in catering and accommodation services in the South Bohemian Region. On the basis of the findings, it is recommended to prepare recommendations for updating the registration of sales (EET) system. This thesis is based on the primary data obtained through the questionnaire survey, which took place between December 2017 and March 2018. The information source was business people of accommodation, catering and hospitality situated in the South Bohemian Region. Respondents were often addressed by e-mail. The questionnaire survey focused on the opinions to the EET before and after its introduction, satisfaction with the material-technical equipment supplier, the resulting complications and the monthly costs associated with the operation of the EET. In addition, three research questions were developed, which were evaluated from the results of the questionnaire survey The questionnaire survey showed that most of the entrepreneurs with their equipment supplier were satisfied. Due to the costs and complications associated with EET, entrepreneurs have not changed the opinion to EET and is still negative.
