Information clues : content analysis of document representations retrieved by the Web search engines Altavista, Infoseek Ultra, Lycos and Open text index

Epp, Mary Anne 05 1900 (has links)
The purpose of this thesis is to identify and quantify the information clues found in the document representations in the World Wide Web environment. This study uses three topics to find document representations: custom publishing, distance education, and tactile graphics. Four Web search engines are used: AltaVista, InfoSeek Ultra, Lycos, and Open Text Index. The findings of the random sample show that the search engines produce little duplication in their display of the results. Just over half of the cases reveal information clues about the document's authorship, origin, format or subject. The summary field shows the highest number of information clues. The title and Uniform Resource Locator fields do not contain many information clues. Few of the fields contain clues about the authorship of the documents. Topical relevance is questionable in many of the cases. The study recommends further research on the comparison of search engines, on the study of searches on the Web for commercial, academic and personal topics, and on information seeking behaviors relating to Web searching. Recommendations are made for Web training and Web page design to assist users in finding relevant information more quickly. / Arts, Faculty of / Library, Archival and Information Studies (SLAIS), School of / Graduate

Dessa forma, este trabalho tem como principal objetivo quantificar e analisar a biomassa de um fragmento florestal de Pinus uncinata pertencente ao Espaço Natural da Montanha de Alinyà, por meio de ferramentas de sensoriamento remoto. O espaço natural está localizado no município de Figòls y Alinyà, na província Lleida, situada na Catalunha – Espanha. Assim, para realizar este estudo foram selecionadas 7 imagens do sensor TM do Landsat 5 correspondentes aos 1984, 2003, 2006, 2008, 2009, 2010 e 2011 com rota 198 e ponto 31. Seguidamente foram trabalhadas as bandas espectrais de cada imagem e calculados a calibração radiométrica, a reflectância e os índices de vegetação NDVI e SAVI. Com os dados LiDAR foram gerados os Modelos Digitais de Terreno (MDT) e realizados os cálculos estatísticos pertinentes para calcular a biomassa florestal, a área basal e o teor de carbono. As informações obtidas foram projetadas em mapas. Como resultado, o NDVI mostrou-se importante por proporcionar a análise temporal do comportamento da massa florestal. No entanto, o NDVI e o SAVI tiveram seus resultados prejudicados pela influência dos efeitos topográficos. Os modelos de regressão linear para biomassa, área basal e teor de carbono tiveram uma correlação satisfatória com os dados de inventário para duas das cinco zonas consideradas. Dessa forma, foi possível estimar estas variáveis florestais para a zona de estudo. O cálculo de biomassa florestal pelos dados LiDAR resultaram em 9.138,6 t para uma área de 69,04 ha, enquanto que os cálculos de inventário resultaram em 11.638,4 tn. O Teor de carbono o cálculo com os dados LiDAR resultaram em 5.425,04 t diante de 6.520,18 t resultantes dos cálculos com os dados de inventário. Portanto se pode afirmar que a tecnologia LiDAR traz ao estudo florestal uma série de aplicações necessárias para uma efetiva gestão dos sistemas florestais. Além disso, o LiDAR apresenta vantagens diante dos outros métodos convencionais, em relação à sua precisão, temporalidade e varredura, ainda mais diante da urgência de se obter resultados confiáveis no cenário atual de mudanças climáticas e vulnerabilidade dos ecossistemas. / The forests have a vital role in carbon capture from the atmosphere. Thus, this work has as its main objective to quantify and analyze biomass of a forest fragment of a Pinus uncinata that belongs to Alinyà Mountain Natural Space, through remote sensing tools. The natural area is located in the County of Figòls y Alinyà, in the Lleida province, located in Catalonia-Spain. In this sense, to conduct this study, 7 images were selected from the Landsat 5 TM sensor corresponding to 1984, 2003, 2006, 2008, 2009, 2010 and 2011 with path 198 and row 31. Subsequently, the spectral bands of each image were manipulated, and then the radiometric calibration, reflectance, and the NDVI and SAVI vegetation indexes were calculated. Using the LiDAR data, the Digital Terrain Models (DTM) were generated, and relevant statistical calculations were made to subsequently calculate the forest biomass, basal area, and carbon content. The information obtained was projected on maps. As a result, the NDVI has supported the study by temporally analyzing the behavior of the forest. However, this index, and even more the SAVI, suffered with the influence of topographic effects. The linear regression models for biomass, basal area, and carbon content had a satisfactory correlation with the inventory data for 2 of the 5 areas considered. In this sense, it was possible to estimate these forest variables for the study area. The calculation of forest biomass by LiDAR data resulted in 9,138.6 ton to an area of 69.04 ha, while the inventory calculations resulted in 11,638.4 ton. For the carbon content, the calculation with the LiDAR data resulted in 5,425.04 ton in comparison with the 6,520 .18 ton resulting from the calculations with the inventory data. Hence, it is safe to say that LiDAR technology brings to the forest study a series of applications that are required for an effective management of forest systems. In addition, the LiDAR presents advantages before other conventional methods, regarding its accuracy, temporality, and range, especially on the urgency of obtaining reliable results in the current scenario of climate change and vulnerability of ecosystems.

Vtah vybraných somatických a motorických ukazatelů k poturální stabilitě u dětí / Relatioship of somatic and motor variables to the postural stability in children

Černá, Lenka January 2011 (has links)
Subject In professional literature progressive development of postural stability related to the age during the childhood is documented which is characterized by decline of amplitude and speed deviations. The postural stability becomes similar to adults by primary school children, specifically in the age of 7 to 10 (Shumway-Cook, Woollacott, 2001) and children switch to more accurate strategy of postural control. The period of primary school is described as positive for motor development. Performance in this period is most considerably influenced by biogenetic factors which include growth factors as for instance body height, weight and body composition. An appropriate movement routine with an adequate amount and quality of movement activity is important for development of children's organism by primary school children. Objective The aim of this work is to describe the changes of chosen parameters of postural stability which are related to the age and gender of primary school children and to submit to analysis the changes in chosen parameters of postural stability in connection with somatic characteristics, movement abilities and movement activity. Methods The summarizing statistical research took place at a primary school where 154 children (85 boys, 69 girls) in the age of 7 to 11 were tested....

Leite, Ana Paula. January 2019 (has links)
Orientador: Luís Gustavo Frediani Lessa / Resumo: O presente estudo baseia-se na aplicação das geotecnologias para discriminar o uso da terra, na bacia hidrográfica do rio Araquá, localizada nos municípios de Botucatu e São Manuel (SP). Teve como objetivo verificar a eficiência da metodologia de associação dos índices radiométricos na identificação de uso da terra, com ênfase nas Áreas de Preservação Permanente, estabelecidas conforme o Código Florestal Brasileiro (Lei nº 12.727/2012). Foram, a partir de imagens do satélite Sentinel-2, produzidas as seguintes associações de índices radiométricos: NDBI-GNDVI-NDWI, NDBI-NDI45-NDWI e NDBI-NDVI-NDWI. Por meio da validação, obtida pela classificação supervisionada gerada em cada uma das três composições, foram identificados usos inadequados. Notou-se o conflito entre a ocupação desordenada de monoculturas canavieiras e as Áreas de Preservação Permanente. A associação NDBI-NDVI-NDWI foi a mais satisfatória para avaliar e discriminar o uso e ocupação da terra na bacia hidrográfica, com coeficiente Kappa de 84%. / Abstract: This study is based on the application of geotechnologies to discriminate land use in the Araquá river basin, located in the municipalities of Botucatu and São Manuel (SP). The objective was verify the efficiency of the radiometric indices association methodology in land use identification, with emphasis on the Permanent Preservation Areas, established according to the Brazilian Forest Code (Law No. 12.727 / 2012). From Sentinel-2 satellite images, the following radiometric index associations were produced: NDBI-GNDVI-NDWI, NDBI-NDI45-NDWI and NDBI-NDVI-NDWI. Through validation, obtained by the supervised classification generated in each of the three compositions, inappropriate uses were identified. The conflict between the disorderly occupation of sugarcane and the Permanent Preservation Areas was noted. The NDBI-NDVI-NDWI association was the most satisfactory to evaluate and discriminate land use and occupation in the watershed with a Kappa coefficient of 84%. / Mestre

HW/SW-database-codesign for compressed bitmap index processing

Lehner, Wolfgang, Haas, Sebastian, Karnagel, Tomas, Arnold, Oliver, Laux, Erik, Schlegel, Benjamin, Fettweis, Gerhard 18 January 2023 (has links)
Compressed bitmap indices are heavily used in scientific and commercial database systems because they largely improve query performance for various workloads. Early research focused on finding tailor-made index compression schemes that are amenable for modern processors. Improving performance further typically comes at the expense of a lower compression rate, which is in many applications not acceptable because of memory limitations. Alternatively, tailor-made hardware allows to achieve a performance that can only hardly be reached with software running on general-purpose CPUs. In this paper, we will show how to create a custom instruction set framework for compressed bitmap processing that is generic enough to implement most of the major compressed bitmap indices. For evaluation, we implemented WAH, PLWAH, and COMPAX operations using our framework and compared the resulting implementation to multiple state-of-the-art processors. We show that the custom-made bitmap processor achieves speedups of up to one order of magnitude by also using two orders of magnitude less energy compared to a modern energy-efficient Intel processor. Finally, we discuss how to embed our processor with database-specific instruction sets into database system environments.
