One of the most popular challenges facing academia and industry is the development of effective techniques and tools for maximizing the availability of data as the most valuable source of knowledge. The internet has dominated as the core for maximizing data availability and XML (eXtensible Markup Language) has emerged and is being gradually accepted as the universal standard format for platform independent publishing and exchanging data over the Internet. On the other hand, there remain large amount of data held in structured databases and database management systems have been traditionally used for the effective storage and manipulation of large volumes of data. This raised the need for effective methodologies capable of smoothly transforming data between different formats in general and between XML and structured databases in particular. This dissertation addresses the issue by proposing a two-way mapping approach between XML and object-oriented databases. The basic steps of the proposed approach are applied in a systematic way to produce a graph from the source and then transform the graph into the destination format. In other words, the derived graph summarizes characteristics of the source whether XML (elements and attributes) or object-oriented database (classes, inheritance and nesting hierarchies). Then, the developed methodology classifies nodes and links from the graph into the basic constructs of the destination, i.e., elements and attributes for XML or classes, inheritance and nesting hierarchies for object-oriented databases. The methodology has been successfully implemented and illustrative case studies are presented in this document.

Na primeira etapa do trabalho, foram desenvolvidos documentos XML para representar os sistemas de agricultura química da Flórida e do Brasil. Um arquivo XSLT foi criado para processar e calcular o fluxo de emergia para cada recurso e visualizar os resultados utilizando o navegador Internet Explorer. As informações registradas nos arquivos XML são: tipo de recurso (contribuição da natureza e da economia humana), quantidade utilizada, unidade de medida, fator de conversão de unidades e transformidades solares. A análise emergética dos sistemas agrícolas pode ser feita de maneira fácil, através da modificação dos campos ¿quantidade de recursos utilizados¿ nos arquivos XML. Na segunda etapa um aplicativo java foi desenvolvido para abrir os arquivos XML e modificar esses campos. Na terceira etapa foram desenvolvidas páginas web dinâmicas utilizando-se as tecnologias JSP e Struts. Com esta ferramenta o usuário pode escolher o sistema, alterar os valores dos recursos utilizados, gravar esses dados no banco de dados e visualizar os resultados. As principais conclusões deste trabalho são: (a) a utilização da tecnologia XML e Java facilita a análise emergética dos sistemas agrícolas; (b) disponibilizando estas ferramentas na internet, o diagnóstico emergético pode ser difundido e amplamente utilizado, sem perder seus padrões de qualidade; (c) esta metodologia pode ser adaptada para representar todos os sistemas agrícolas brasileiros, incluindo os modelos ecológicos como também os químicos / Abstract: This work had the goal of developing computational tools to make the emergy evaluation of agricultural systems using the technologies XML, XSLT, Java, JSP, Struts and the MySQL database. At the first stage of this work, XML documents were developed to represent the chemical agricultural systems of Florida and Brazil. A XSLT archive was created to process and to calculate the emergy flows for each resource and to visualize the results using the Internet Explorer Navigator. The information stored on the XML archives are: type of resources (contribution of nature and economy), amount used, units of measure, units conversion factors and solar transformities. The emergy analysis of agricultural systems can be done in an easy way, through the modification of the ¿quantity of resources used¿ fields on the XML archives. At the second stage, a java application was developed to open the XML archives and to modify these fields. At the third stage dynamic web pages were developed using the technologies JSP and Struts. With this tool the user can choose the system, modify the values of used resources, save these data on the database and visualize the results. The main conclusions of this work are: (a) the use of XML and Java technologies make easier the emergy analysis of agricultural systems; (b) making these tools available at the internet, the emergy diagnosis can be spread out and widely used, without losing its quality standards; (c) these methodologies can be adapted to represent all the Brazilian agricultural systems, including the ecological models as well as the chemical models / Mestrado / Engenharia de Alimentos / Mestre em Engenharia de Alimentos

Esta infra-estrutura baseia-se em um modelo de componentes neutro em termos de tecnologia e especificado inteiramente em UML (Unified Modeling Language). A plataforma utiliza Web Services para comunicação síncrona entre os componentes. Um Serviço de Notificação baseado em documentos XML (Extensible Markup Language) foi desenvolvido para suporte a notificação assíncrona entre componentes. Um exemplo de aplicação na área de gerência de redes ilustra as funcionalidades da infra-estrutura / Abstract: This work presents an infrastructure for supporting component-based software development for mobile devices with limited resources regarding processing power and storage. This infrastructure is based on a neutral component model in terms of technology and specified entirely in UML (Unified Modeling Language). The platform employs Web Services for synchronous communication between components. A Notification Service based on XML (Extensible Markup Language) documents was developed in order to support asynchronous communication among the components. An example of application in the field of network management illustrates the functionalities of the infrastructure / Mestrado / Engenharia de Computação / Mestre em Engenharia Elétrica

Master’s thesis deals with implementation of a European standard DATEX II. This standard specifies the data format for information transmission in road transport. The road traffic is flowing streams of current information. For the work was selected network of meteorological stations, which will publish the measured data, ie weather conditions of road transport. Measured data will be available to consumers in the format DATEX II. Implementation will be operational in its entirety meteorological station from design to the actual web service that will produce data information for consumers.
