[pt] A maior parte dos bancos de dados existentes é projetada de maneira independente e, portanto, é geralmente implementada utilizando diferentes esquemas conceituais, criando um contexto de heterogeneidade em níveis sintático, estrutural e semântico. Não obstante, quando um conjunto de bancos de dados se refere a um mesmo domínio, eventualmente, surge a necessidade de integrá-los em um mesmo banco, ou de intermediar o acesso ao conjunto de bancos de forma transparente. Para tratar o problema da heterogeneidade, torna-se necessário o alinhamento dos esquemas de cada um dos bancos de dados envolvidos. Esse processo geralmente é feito por especialistas de domínio, mas tende a ser um trabalho muito tedioso e propenso a erros. Esta dissertação apresenta o CatalogMatcher, uma infra-estrutura de software para alinhamento de catálogos heterogêneos. Um catálogo armazena dados sobre um conjunto de objetos de um determinado domínio, tipicamente classificados por algum tipo de taxonomia ou tesauro. O CatalogMatcher contém componentes que implementam estratégias de alinhamento de catálogos heterogêneos utilizando abordagens baseadas em instâncias. / [en] Most databases are independently designed and, therefore, are usually implemented using different conceptual schemas, which creates a context of syntactic, structural and semantic-level heterogeneity. Nevertheless, when a set of databases refers to a common domain, it may become necessary to integrate them into a single database, or to intermediate access to the databases in a transparent way. To deal with the heterogeneity problem, it becomes necessary to align the conceptual schemas. This process is usually carried out by domain specialists, and tends to be tedious and error-prone. This dissertation presents the CatalogMatcher, a software infrastructure for catalog matching. A catalog stores data about a set of objects from a specific domain, typically classified by some sort of taxonomy or thesaurus. The CatalogMatcher contains components that implement instance-based alignment strategies.

As propostas da Web Semântica e as possibilidades apresentadas pelo Linked Data para descrição de acervos e a catalogação em bibliotecas para promoção e a ligação de dados, surgem como instrumentos importantes na gestão do dado bibliográfico. A questão desse estudo caracteriza-se em quais as possibilidades de ligação de dados bibliográficos nas práticas de Linked Data? O objetivo geral é analisar os principais aspectos da proposta do Linked Data com o intuito de promover a ligação e interoperabilidade de dados bibliográficos na Web. A metodologia é caracterizada por uma pesquisa qualitativa e exploratória por meio de revisão bibliográfica sobre o Linked Data. A relevância e justificativa da proposta é corroborar com conhecimento teórico sobre os instrumentos que orientam a ligação de dados do domínio bibliográfico na Web, pois trará benefícios aos usuários e a prática do catalogador. Como resultados foram identificadas iniciativas que estão trabalhando em estruturar seus catálogos para promoção do Linked Data, entre elas destacaram-se os trabalhos da Library of Congress e da Online Computer Library Center (OCLC) dos Estados Unidos e o trabalho da Europeana. A primeiro momento, a estruturação dos dados de bibliotecas mostra-se um trabalho minucioso e detalhado. Entretanto, com o uso das tecnologias da Web Semântica e os princípios do Linked Data, apresenta maior flexibilidade para construção de registros. Dessa forma, um catalogador poderá realizar ligações entre recursos por meio dos identificadores únicos, evitando que o catalogador realize novamente a descrição desse outro recurso. / The Information Centers need constant updating without using the available technologies to optimize the management of informational resources. As proposals of the Semantic Web and as possibilities presented by Data linked to description of collections and a cataloging in libraries for the promotion and connection data, as important tools in the management of the bibliographic data. The question of this study is characterized in such as possibilities of connection of bibliographic data in the practices of Linked Data? The principal objective is to analyze the main aspects of the Linked Data proposal in order to promote the connection and interoperability of bibliographic data on the Web. The methodology is characterized by a qualitative and exploratory research through a bibliographic review of Linked Data. The relevance and justification of the proposal is corroborated with theoretical knowledge about the instruments that guide the bibliographic domain data link in the Web, as it will bring benefits to the users. Thus, initiatives have been identified that are working on structuring their catalogs to promote Linked Data, including the work of the Library of Congress and the Online Computer Library Center (OCLC) in the United States and the work of Europeana. At first, the structuring of library data shows a detailed and detailed work. However, with the use of Semantic Web technologies and the principles of Linked Data, it presents greater flexibility for the construction of registries. In this way, a cataloger can establish connections between resources through unique identifiers, causing the cataloger to re-describe the other resource.

nÃo hà / Este trabalho busca compreender o processo de circulaÃÃo da obra do pintor, desenhista e gravador Raymundo BrandÃo Cela (1890-1954), desde seu perÃodo de formaÃÃo na Escola Nacional de Belas Artes (ENBA), no inicio do sÃculo XX, atà exposiÃÃes realizadas nos dias de hoje. Por meio da reproduÃÃo das obras do artista, impressas em catÃlogos de exposiÃÃo, procuro construir uma sociologia do objeto artÃstico, ou seja, o modo como determinadas convenÃÃes sÃo acionadas para classificÃ-las e como tal classificaÃÃo recebe camadas de significados. Portanto, nÃo apenas a ordem discursiva sobre as obras terà lugar de destaque, mas tambÃm o suporte no qual elas circulam: exposiÃÃes, catÃlogos, livros-catÃlogo, folhetos e jornais. No caso dos catÃlogos de exposiÃÃo, estes tÃm lugar de destaque, pois trazem à tona a maneira pela qual os mundos da arte atuam, ou seja, como fomentam um sistema de enunciados sobre exposiÃÃes, artistas e obras, a partir de uma rede de interdependÃncia presente nas instituiÃÃes da arte. Tal abordagem contribuirà para os debates â ainda iniciais â sobre a histÃria dos impressos nos mundos da arte, alÃm de levantar questÃes sobre a arte brasileira por intermÃdio das exposiÃÃes e coleÃÃes de arte.

Estima-se, ainda, que 40% da água destinada à irrigação é perdida por percolação e escoamento superficial, o que pode causar impactos diretos no solo e na água tais como erosão, lixiviação de nutrientes, compactação do solo e selamento superficial, além do assoreamento de corpos d¿água, diminuição da qualidade e desperdício do recurso hídrico, promovendo o impacto ambiental negativo na bacia hidrográfica. Com a regulamentação da legislação que prevê a cobrança pelo uso da água, a agricultura irrigada deverá merecer especial atenção, incluindo programas de orientação para o manejo correto dos equipamentos, disseminando conhecimento acerca de conservação da qualidade da água e do solo. O presente estudo foi realizado nas áreas irrigadas dos municípios de Jundiaí, Jarinú e Campo Limpo Paulista, pertencentes à bacia hidrográfica do rio Jundiaí-Mirim, no Estado de São Paulo (Brasil), e teve por objetivo desenvolver uma metodologia para a realização de diagnóstico sobre o uso da água na irrigação de culturas em uma bacia hidrográfica e para o cadastramento de agricultores irrigantes. O estudo também incluiu a avaliação simplificada da qualidade da irrigação nas propriedades rurais a partir de um índice de qualidade da irrigação (IQI) baseado em parâmetros indicadores de qualidade relacionados à água, ao solo, à cultura irrigada e ao manejo da irrigação. No desenvolvimento da metodologia foram utilizados pesquisas de campo com questionários, Sistema de Posicionamento Global (GPS), Sistema de Informação Geográfica (SIG) e programas computacionais específicos para estes sistemas. Com os resultados obtidos foi elaborado o diagnóstico do uso da água pela irrigação local e disponibilizado um banco de dados em SIG, para o uso de órgãos públicos e interessados no desenvolvimento de políticas de gerenciamento agroambiental e de recursos hídricos. Também foi possível avaliar o conhecimento dos agricultores sobre a cobrança pelo uso de recurso hídrico e desenvolver uma metodologia para a estimar a qualidade da irrigação a partir de um índice simplificado (IQI), com a identificação de aspectos relacionados ao uso de sistemas de irrigação / Abstract: Recent researches demonstrate that the use of water for agriculture represents 60% of total consumption of freshwater in Brazil and that many irrigation systems do not have any control of the use of water for this activity. Also, it is estimated that 40% of the water applied in irrigation is misused by percolation and superficial drainage, what generates a great number of impacts to soil and water, such as compactation and sealing of superficial soil, silting up of water bodies, decrease of quality, and wasting of hydric resource, promoting a negative effect on the river basin. With the duty of payment of a tariff for use of water, irrigated agriculture will deserve special attention, with the developmente of education programs to stimulate the correct handling of equipments and to disseminate knowledge about water and soil conservation. This study was carried out on irrigated areas in Jundiaí, Jarinú and Campo Limpo Paulista County, located in the Jundiaí-Mirim River basin, in São Paulo state (Brazil), with the purpose to develop a simple methodology to diagnose the use of water for crop irrigation in the area and to catalog the farmers. It also included an evaluation of the irrigation quality process in the farms using an Irrigation Quality Index (IQI), which is based on parameters related to water, soil, irrigated crop and handling of equipments. In the methodology development, it was used field research with questionnaires, Global Position System (GPS), Geographical Information System (GIS) and specific software for these systems. With the obtained results, it was elaborated the analysis of the use of water in local irrigation and organized a digital databank, available for use by public institutions and other people interested on the development of public policies on environmental monitoring and water resources. It was also possible to evaluate the farming knowledge about the duty of payment of a tariff for use of water, and to develop a methodology to estimate de quality of irrigation with some simple parameters that identify aspects related to the use of irrigation systems / Mestrado / Agua e Solo / Mestre em Engenharia Agrícola

The research goal was to find out the current and possible level of procurement automation and its contribution to less routine and more creative jobs. The goal was accomplished by literature review and data collection via survey. The data collected evaluated enterprises in developing and developed countries. The research hypothesis of developing countries automating more than developed ones was not supported by the data tested via Mann-Whithey U test. The data collected was from 146 respondents from all around the world. Therefore, there are limitations of the conclusions. The thesis and its survey contributes to the knowledge about the level of procurement automation.

The whole work is dealing with so-called. OpenData. Since this topic is very extensive, this paper focuses only on cataloging tools (catalogs) for open data. The main reason for this narrower focus is still great variability and new technologies that are of interest not only for the individuals or institutions but also for the whole public administration. For example at the beginning of this work none Czech national open data catalog existed, in the course of writing it managed to launch and now works almost flawlessly. Therefore, it is an important part of a retrospective view. The main objective of this work is to analyze the situation of the national catalogs of open data in selected locations, mapping the requirements of catalogs by avaible documents, creation of criteria and assessed according to criteria selected cataloging tool. Benefits include compiled criteria that can serve additional work or other purposes, and the aforementioned retrospective view. The structure of the work will be divided into several basic blocks, which can be summarized into the structure: Introduction, practical part, analytical part, conclusion. The introduction explains the reasons and aims of work and achievement. The practical part describes the past and present status issues. In the analytical part are assessed as suitable criteria / requirements that are applied to the selected tool. In the end everything is summed up.

The target of my dissertation is to draw the character of the graphical works created by Jan Jiří Balzer which are kept in the collections of the National gallery in Prague. The resource of the graphical works of J. J. Balzer according to Norbert Grund includes more than five hundred and fifty items which remained almost non-elaborated. That's why, I would try to sort out and catalogue them. Beyond my dissertation, I would like to introduce a personality of the contemporary artist who is at the time the founder of an engraving plant and a successful businessman - who managed to interest the Czech graphical market of the second half of the 18-th century. As well as, I try to clarify, on base of the critical studying of available sources and literature, the circumstances which lead the artist to the graphical performance of the Norbert Grund's painting works. And last but not least I would like to outline the production of Jan Jiří Balzer in context of the contemporary creation and collecting of the 18-th century.

There is a great need for digital libraries that are flexible, scalable, and reliable. Few such systems exist. Little is known about how to build them. This thesis addresses these problems by enhancing a prototype digital library system with the aim of making it more flexible, scalable, and reliable. We hypothesize that: 1) adding a new (user information) layer and maintaining weak coupling in the design of a digital library system can help achieve system flexibility; 2) optimizing network connection usage and facilitating distribution of computation and disk operations in system design can help achieve system scalability; and 3) applying good software processes can help university students produce a very reliable system. Approaches based on the above hypothesis were used in the project of Reengineering the MARIAN System in Java. The results of the project and experiments verified the correctness of the hypothesis. The results of this thesis may help inform future digital library design and implementation projects to produce flexible, scalable, and reliable systems. / Master of Science

Indiana University-Purdue University Indianapolis (IUPUI) / Static code analysis tools are known to flag a large number of false positives. A false positive is a warning message generated by a static code analysis tool for a location in the source code that does not have any known problems. This thesis presents our approach and results in identifying and documenting false positives generated by static code analysis tools. The goal of our study was to understand the different kinds of false positives generated so we can (1) automatically determine if a warning message from a static code analysis tool truly indicates an error, and (2) reduce the number of false positives developers must triage. We used two open-source tools and one commercial tool in our study. Our approach led to a hierarchy of 14 core false positive patterns, with some patterns appearing in multiple variations. We implemented checkers to identify the code structures of false positive patterns and to eliminate them from the output of the tools. Preliminary results showed that we were able to reduce the number of warnings by 14.0%-99.9% with a precision of 94.2%-100.0% by applying our false positive filters in different cases.

This work concerns optimalization of web pages for finders in the way that the web pages could be placed on best positions. The key of success for optimalization of web pages is the combination of some basic rules. The comparison of advantages of different ways of navigation and creation of menu, speed optimalization of pages loading, texts optimalization with the help of chosen key words, principles of choosing the key words, item placing on web pages and comparison of design, marketing and custom view of making the web pages. First of all, we will look on the difference between catalogues and full text finders, their historical development and current ratio of finders on our market. Subsequently we will describe the presumptions for optimalization from the resource code and programming languages point of view, which are used on web pages. The most important part of our interest is the optimalization methods of web pages content and also the methods which are considered as forbidden. The final implementation is made in PHP language.
