Estes problemas não se restringem a produtividade agrícola, como também favorecem o empobrecimento do meio rural, a poluição e assoreamento dos cursos d’água, a dependência financeira e tecnológica dos sujeitos sociais etc. Para compreender as dinâmicas e os fatores relevantes na perda de solo foi aplicado distintos métodos de determinação, um de estimação direta, por meio das parcelas de monitoramento com pinos de erosão e um indireto, por meio da Equação Universal de Perda de Solos (EUPS), que permitissem a comparação dos resultados obtidos em campo com os da aplicação do modelo. O estudo foi realizado em duas propriedades agrícolas que possuem características naturais e de uso e ocupação distintas, atribuindo-lhes complexidades espaciais particulares. Uma localiza-se em Getulina e é destinada a pecuária e a outra localiza-se em Vera Cruz com a produção de café. Foi possível identificar nas propriedades agrícolas características naturais que tornam seus solos suscetíveis a perda por processos erosivos, porém, que as formas de uso e ocupação destes espaços foram fundamentais para o entendimento dos totais de perda registrados pelos métodos de determinação. Esta complexidade fundamenta a necessidade de abordar a perda de solo como fenômeno geográfico, decorrente de aspectos naturais e sociais que expressam demandas, interesses e funcionalidades socialmente construídas que fundamentam sua apropriação. / Looking to understanding the dynamics involving the soil loss, aiming at both its measurement as well as the actions aimed use at their conservation and recovery, is gaining space in the scientific world due to environmental and economic problems resulting from this degradation. These problems are not restricted to agricultural productivity, but also promote rural impoverishment, pollution and siltation water courses, social subjects financial and technological dependence, etc. The different methods of determination, a direct estimation, through the monitoring plots with erosion pins and an indirect, through the Universal Soil Loss Equation (USLE) was applied to understand the dynamics and relevant factors on soil loss and also to allow the results comparison obtained in the field where was applied the models. The study was conducted in two farms where we could find different use and occupation natural characteristics assigning them particular spatial complexities. One farm is located in Getulina and is intended for livestock (animals) and the other is located in Vera Cruz where they grow coffee, both in southeastern Brazil, São Paulo State. It was possible to identify the properties that make their natural features agricultural soils susceptible to loss through erosion, however, that the use and occupation forms of these spaces were fundamental for the understanding the loss totals recorded by determination methods. This complexity is motivated by the need to address the soil loss as geographical phenomenon, resulting from natural and social aspects that express demands, interests and socially constructed features that underlie your ownership. / 2014/02230-6

This diploma work analyses recreation in the cabins, gardening, working on personal plots and wine making in the district of Hodonín. First of all, it deals with cabin typology and properties in the gardens, private plots and vineyards, which are not used for staying in (arbours). These investigated properties used for recreation form summer settlements {--} used for staying in or other purpose {--} arboured or both, settlements of different types. These typologies we apply to territorial charting of cabins, arbours and their settlements in Hodonín district. (There have been charted 5 376 cabins and 4 939 arbours). The diploma work contains the summary of enviromental problems and those connected with territorial planning and other activities mentioned above.

In this thesis, a 3D approach to visualize software metrics is presented. Software metrics are attributes of a piece of software or its specification. They generally contain a set of multivariate time-series data and can be displayed, for example, as a Kiviat diagram consisting of axes and polylines. The aim of this work is to design a Win32 application that can load multivariate time-series data from a file and visualize it as an interactive 3D Kiviat diagram. There has been an approach that can display software metrics by using 2D Kiviat diagrams, but there are still some drawbacks on it. Since a better visualization of software metrics can help the developer to control the quality of software products more easily, this thesis improved the existing approach by extending 2D Kiviat diagram to 3D Kiviat diagram.

No. of bitstreams: 1 Elias Vasconcelos Neto.pdf: 488878 bytes, checksum: 3ba462c0237a8d31abd240eff4c8da1e (MD5) Previous issue date: 2012-06-01 / CAPES - Coordenação de Aperfeiçoamento de Pessoal de Nível Superior / The Amazon forest is a mixture of hundreds of species, with different ages and growth rates, knowing them, both for researchers as to Amazonian populations, is a major challenge. The aim of this study was to perform species ecological and functional grouping of Acre state forests. This work was developed from data of 95 permanent plots, with one hectare each (100 x 100m), sub-divided into plots of 10 x 10 and installed on Projeto de Colonização (PC) Pedro Peixoto, State Forest of Antimary (FEA) and ST Management. In these sub-plots all individuals with diameter at breast height (DBH) greater than or equal to 10 cm were measured. The collect period was from 1996 to 2007, with measurements at non-regular intervals. The clustering process occurred in three stages: (1) cluster analysis to group the most populous species. For this process, the variables employed were Periodic Annual Increment in diameter - IPADAP Medium in High, Medium and Low competition and 95% percentile of cumulative frequency distribution of diameters using Ward hierarchical method; (2) discriminant analysis, to allocate the least populated species to the groups formed, using variables of the 95% percentile of the cumulative frequency distribution of diameters and the average annual periodic increments in diameter (IPADAP) and the Fisher method, (3) subjective stage, used to allocate species with few individuals to formed groups. Ward method used in cluster analysis and the Fisher method used for discriminant proved to be effective in creating and training groups. The use of these methods resulted in formation of ten groups of species with high growth rates of similarity between individuals of the same group and low similarity between groups. Variables: IPADAP for stand and IPADAP in low, medium and high competition and P95 of cumulative frequency distribution of diameters shown are variables useful for the purposes of grouping of species. Variations in the growth rates for the overall mean data were reduced when calculated for each group of species. / A floresta amazônica é uma mistura de centenas de espécies, com diferentes idades e taxas de crescimento, o seu conhecimento, tanto para pesquisadores quanto para as populações amazônicas, é um grande desafio. O objetivo deste estudo foi efetuar o agrupamento ecológico e funcional de espécies presentes na floresta do Estado do Acre. Este trabalho foi desenvolvido a partir de dados de 95 parcelas permanentes, com área de um hectare cada (100 x 100m), subdividida em subparcelas de 10 x 10 e instaladas no Projeto de Colonização (PC) Pedro Peixoto, Floresta Estadual do Antimary (FEA) e ST Manejo. Nestas sub-parcelas todos os indivíduos com diâmetro a altura do peito (DAP) maior ou igual a 10 cm foram medidos. O período de coleta foi de 1996 até 2007, com medições em intervalos de tempo não regulares. O processo de agrupamento ocorreu em três estágios: (1) análise de Cluster para fazer o agrupamento das espécies mais populosas. Para esse processo foram empregadas as variáveis Incremento Periódico Anual em diâmetro - IPADAP médio em Alta, Media e Baixa competição e percentil 95% da distribuição de frequência cumulativa dos diâmetros pelo método hierárquico Ward; (2) análise Discriminante, para alocar as espécies menos populosas aos grupos formados, utilizando-se as variáveis percentil 95% da distribuição de frequência cumulativa dos diâmetros e os incrementos periódicos médios anuais em diâmetro (IPADAP) e o método de Fisher; (3) estágio subjetivo, utilizado para alocar as espécies com poucos indivíduos aos grupos formados. O método Ward utilizado na análise de Cluster e o método de Fisher usado no discriminante demonstraram-se eficazes na criação e formação dos grupos. A utilização destes métodos resultou na formação de dez grupos de espécies com crescimentos de alta similaridade entre indivíduos do mesmo grupo e baixa similaridade entre grupos. As variáveis: IPADAP para o povoamento e IPADAP em baixa, média e alta competição e P95 da distribuição de frequência cumulativa dos diâmetros demonstraram-se variáveis úteis para a realização do agrupamento de espécies. As variações nas taxas de crescimento relativas à média total dos dados foram reduzidas quando calculada para cada grupo de espécies.

This dissertation locates the emergence of a modern conception of information in the work of Victorian novelists and novel critics. In a period where the novel is most often understood as a genre interested in depicting total worlds, Victorian novelists lingered on aesthetic and social methods for organizing the informational minutiae that made up such worlds. Novelists developed baroque plots around marriage registers and memos. Even more notably, they conducted research: consulting and creating notebook lists, tabular arrays, archival records, and pre-printed survey forms as strategies for linking the work and the world. In this dissertation, I draw on both literary critical analysis and original archival research to show how the research of Victorian novelists wrestled with the social and aesthetic conventions of abstract data. At its core, my project shows how nineteenth-century definitions of authorship and narrative form emerge from some of the most routinized practices of storage, search and retrieval.

This article presents the derivation of the thermodynamic expressions for the activation free energy and reaction rate constant for cosolvent reaction systems. These expressions account for the factors that are specific to solution-phase reactions, which include isotropic electrostatic effects and close-range solvent−solute interactions. This article discusses the idea that electrostatic effects can be correlated with the isotropic relative permittivity, and solvent−solute interactions can be correlated with the cosolvent mole fraction. This article also shows that this type of thermodynamic analysis is necessary for understanding certain nuances of solution-phase reaction processes not tractable by other types of analyses.

ε-Differential Privacy (DP) has been popularly used for anonymizing data to protect sensitive information and for machine learning (ML) tasks. However, there is a trade-off in balancing privacy and achieving ML accuracy since ε-DP reduces the model’s accuracy for classification tasks. Moreover, not many studies have applied DP to time series from sensors and Internet-of-Things (IoT) devices. In this work, we try to achieve the accuracy of ML models trained with ε-DP data to be as close to the ML models trained with non-anonymized data for two different physiological time series. We propose to transform time series into domain-specific 2D (image) representations such as scalograms, recurrence plots (RP), and their joint representation as inputs for training classifiers. The advantages of using these image representations render our proposed approach secure by preventing data leaks since these image transformations are irreversible. These images allow us to apply state-of-the-art image classifiers to obtain accuracy comparable to classifiers trained on non-anonymized data by ex- ploiting the additional information such as textured patterns from these images. In order to achieve classifier performance with anonymized data close to non-anonymized data, it is important to identify the value of ε and the input feature. Experimental results demonstrate that the performance of the ML models with scalograms and RP was comparable to ML models trained on their non-anonymized versions. Motivated by the promising results, an end-to-end IoT ML edge-cloud architecture capable of detecting input drifts is designed that employs our technique to train ML models on ε-DP physiological data. Our classification approach ensures the privacy of individuals while processing and analyzing the data at the edge securely and efficiently.

Trajectory modeling is one of the most important aspects of any mission design. The trajectory should be able to propagate the S/C to the final destination while optimizing the flight duration, the total change in velocity and also the total launch mass. The Spacecraft Trajectory Optimizer (STO) tool described in this report first solves the Gauss Lambert problem and generates initial departure and arrival conditions which can also be expressed as porkchop plots. These initial conditions are then used as input to optimize the flight steps which are based on a patched conic approximation with the elliptical transfer with respect to the Sun and the hyperbolic transfers at the departure and arrival planet's sphere of influence. The tool is completely based on MATLAB 2007 or later and uses ODE45 for trajectory propagation and FMINCON with Active-set algorithm for optimization. The results obtained in house were compared with four Mars Sample return orbits calculated at ESOC and there is a very good correlation between the required change in velocities and transfer duration for e.g. Orbit case: O22S, ESOC values: total Delta V = 3.946 - 4.119 [km/s], TOF = 329 - 342 [days] &amp; STO values: Delta V = 3:986 [km/s] &amp; TOF = 335 [days]. The in house data was also used as an input in the System Tool Kit (a professional trajectory calculation software) for modeling an interplanetary trajectory to Mars and the S/C arrived at Mars without any optimization. Therefore, even though the STO does not have all the capabilities of a professional software it can be used for preliminary mission analysis as it offers quite accurate results for interplanetary transfers. / <p>Validerat; 20131127 (global_studentproject_submitter)</p>
