Este trabalho descreve o desenvolvimento de um ambiente integrado para modelagem, simulação e implementação de sistemas de tempo real distribuídos (STRD), especialmente aqueles voltados para automação industrial. O ambiente proposto faz use do paradigma de orientação a objetos, sendo baseado no ambiente SIMOO, desenvolvido no Âmbito de uma tese de doutorado no CPGCC. A motivação para a realizado deste trabalho surgiu através de alguns estudos de caso, que constataram que as ferramentas CASE existentes não incorporavam todas as propriedades desejadas em termos de suporte para modelagem e implementação dos STRD. Dentre estas propriedades, destacam-se a capacidade para especificação de restrições temporais, o suporte a simulação do modelo desenvolvido e a capacidade de geração automática de código para a aplicação final. O ambiente proposto tem por objetivo suprir as carências observadas, adicionando ao ambiente SIMOO original facilidades para a descrição de restrições temporais e facilidades para descried° de comportamento do modelo desenvolvido. Além disso, é incorporada ao ambiente a capacidade de geração automática de código em uma linguagem que suporte as restrições temporais descritas no modelo. Este trabalho foi desenvolvido no contexto do projeto ADOORATA (A Distributed Object-Oriented Architecture for Real-Time Automation), como parte do Programa de Cooperação entre Brasil e Alemanha, financiado pelas agencias CNPq e DLR. / This work describes the development of an integrated object-oriented environment for modeling, simulation and implementation of distributed real-time systems (DRTS), especially those conceived for industrial automation. This work extends the SIMOO environment, conceived as part of a Ph.D. thesis in the CPGCC at Federal University of Rio Grande do Sul. Its motivation began during some case studies, which concluded that existing CASE tools don't incorporate all the desired features for modeling and implementation of DRTS. Among these features, capacities to specify timing constraints, to simulate/animate the model and to automatically generate the final application code are highlighted. The proposed environment intends to overcome these lacks, adding to the original environment features for the specification of timing requirements and the application behavior, allowing the creation of an object-oriented simulation model. Additionally it automatically generates the application executable code, which makes use of the incorporated specifications to guarantee its correctness. This work has been developed within the context of the ADOORATA project (A Distributed Object-Oriented Architecture for Real-Time Automation), as part of the Brazilian-German Cooperation Program, sponsored by CNPq and DLR.

Com isto vê-se crescer a demanda por novas aplicações colaborativas. Neste contexto vimos surgir uma classe de aplicações denominada de Ambientes Colaborativos. Embora muito se tenha avançado com o surgimento de ambientes de propósito geral, onde os AVAs e CMSs se destacam, tem-se observado que estes nem sempre se ajustam às necessidade e preferências de grupos específicos. É portanto desejável a oferta de facilitadores para criação de propostas inovadoras. Nesse trabalho, é apresentado um framework para o desenvolvimento de ambientes pertencentes a esta classe de aplicações. O objetivo da proposta é facilitar o processo de construção deste gênero de ambientes, promovendo artefatos facilitadores para uso, segundo a abordagem do Modelo 3C de colaboração. A proposta foi construída a partir da etodologia Hot-Spot Driven Design acoplados com boas práticas da Engenharia de Software, além de utilizar os conceitos de Unidade de Produção Intelectual (UPI) e Veículos de comunicação (Vcom) para modelagem dos espaços de colaboração, propostos no projeto MOrFEu. Por fim, o trabalho também apresenta um protótipo do framework proposto, como forma de materializar os conceitos descritos e realçar a viabilidade da proposta, criando-se um conjunto de ambientes colaborativos / The Web offers an unprecedented opportunity to promote the integration of persons to perform activities of any nature, whether for work, for leisure or for study. With this one sees growing demand for new collaborative applications. In this context we have seen an emerging class of applications called Collaborative Environments. Although much progress has been made with the emergence of general-purpose environments, where VLEs and CMSs stand out, it has been observed that these do not always fit the needs and preferences of specific groups. It is therefore desirable to offer facilitators for creating innovative proposals. In this work, we present a framework for the development of environments of this class of applications. The aim of the proposal is to facilitate the process of building this kind of environments, promoting artifacts facilitators to use, according to the approach of the 3C collaboration model. The proposal was built on the methodology Hot-Spot-Driven Design coupled with best practices of software engineering, in addition to using the concepts of Intellectual Production Unit (UPI) and communication vehicle (Vcom) for modeling collaborative spaces proposed in the MOrFEu project. Finally, the work also presents a prototype of the proposed framework as a way of materializing the concepts described and enhance the viability of the proposal, creating a set of collaborative environments

Recentes avanços proporcionaram às grades computacionais um bom nível de maturidade. Esses sistemas têm sido implantados em ambientes de produção de qualidade na comunidade de pesquisa acadêmica e vêm despertando um grande interesse da indústria. Entretanto, desenvolver aplicações para essas infra-estruturas heterogêneas e distribuídas ainda é uma tarefa complexa e propensa a erros. As iniciativas de facilitar essa tarefa resultaram, na maioria dos casos, em ferramentas não integradas e baseadas em características específicas de cada grade computacional. O presente trabalho tem como objetivo minimizar a dificuldade de desenvolvimento de aplicações para a grade através da construção de um ambiente integrado e extensível de desenvolvimento (IDE) para computação em grade chamado InGriDE. O InGriDE fornece um conjunto único de ferramentas compatíveis com diferentes sistemas de middleware, desenvolvidas baseadas na interface de programação Grid Application Toolkit (GAT). O conjunto de funcionalidades do InGriDE foi desenvolvido com base na plataforma Eclipse que, além de fornecer um arcabouço para construção de IDEs, facilita a extensão do conjunto inicial de funcionalidades. Para validar a nossa solução, utilizamos em nosso estudo de caso o middleware InteGrade, desenvolvido no nosso grupo de pesquisa. Os resultados obtidos nesse trabalho mostraram a viabilidade de fornecer independência de middleware para IDEs através do uso de uma interface genérica de programação como o GAT. Além disso, os benefícios obtidos com o uso do Eclipse como arcabouço para construção de IDEs indicam que os recursos fornecidos por esse tipo de arcabouço atendem de forma eficiente as necessidades inerentes ao processo de desenvolvimento de aplicações para a grade. / Computational grids have evolved considerably over the past few years. These systems have been deployed in production environments in the academic research community and have increased the interest by the industrial community. However, developing applications over heterogeneous and distributed infrastructure is still a complex and error prone process. The initiatives to facilitate this task, in the majority of the cases, resulted in isolated, middleware-specific tools. This work has the objective of minimizing the difficulty of developing grid applications through the construction of an integrated and extensible development environment for grid computing, called InGriDE. InGriDE provides a unique set of tools, compliant with different middleware systems, based on the Grid Application Toolkit (GAT). We developed the InGriDE set of features, based on the Eclipse platform, which provides both a framework for building IDEs and the possibility to extend the initial set of features. To validate our solution we used the InteGrade middleware, developed in our research group, as our case study. The results obtained from our work showed the viability of providing middleware independence to IDEs through the use of a generic application programming interface like GAT. Moreover, the benefits obtained through the use of Eclipse as our framework for building IDEs indicates that this kind of framework satisfies the requirements inherent to the grid application development process in a efficient way.

<p>Dolina Lima i Polimlje predstavljaju složenu prostornu celinu u kojoj se prepliću različiti prirodni i antropogeni procesi. Analiza elemenata prirodne i sociokulturne sredine, njihovo turističko-ekolo&scaron;ko vrednovanje i objedinjavanje treba da pokažu svrsishodnost ulaganja u turizam i ekologiju Polimlja. Tema doktorske disertacije postavljena je tako da se kroz trinaest komplementarnih poglavlja dođe do projektovanog cilja o mogućnostima razvoja pojedinih vrsta ekoturizma. Prikaz objedinjenih sadržaja u određenom obimu doprinosi boljem poznavanju Polimlja i omogućava lak&scaron;i pristup operativnom delu turističkog planiranja u uslovima ekolo&scaron;ke i turističke održivosti. Takva konstatacija proističe iz utvrđenih vrednosti dobijenih analizom parametara kvaliteta životne sredine i sociokulturne ba&scaron;tine. Na osnovu dobijenih vrednosti izveden je zaključak da turizam u ekolo&scaron;kom ambijentu Polimlja s obzirom na kvalitet prirodnih elemenata može postati dominantna delatnost i pored negativih iskustava u oblasti životne sredine iz druge polovine dvadesetog veka.</p> / <p>The valley of the river Lim and Polimlje represent a complex regional entity in which different natural and antropogenic processes interact. Analysis of elements of the natural and socio-cultural environment, their tourist-ecological valorization and combination should show the appropriateness of investing in the tourism and ecology of Polimlje. The theme of this Ph.D. thesis is defined in such a way that through thirteen complementary chapters it arrives at the projected target about the possibillities of the development of some types of eco tourism. Presentation of the combined content to a certain degree contributes to a better knowledge of Polimlje and enables easier access to the operative part of tourist planning in conditions of ecological and tourist maintenance. Such a conclusion is the result of established values obtained by analysis of the quality of the environment and the socio-cultural heritage. Based on the values obtained it may be concluded that tourism in the ecological environment of Polimlje, having in mind the quality of natural elements, could become a dominant activity regardless of negative experiences in the environmental field in the second half of the twentieth century.</p>

MSc thesis - Faculty of Engineering / Service creation in the Next Generation Network (NGN) is focused around software creation and borrows heavily from the Software Engineering community. In the NGN, telecommunication companies demand simple, rapid and economical service creation. The key to this type of service creation is software re-use. Software re-use is a conundrum where limited, dedicated solutions exists. These solutions include amongst others Enterprise JavaBeansTM (EJBs), design patterns and object-oriented programming. The Telecommunications Information Networking Architecture- Conformance And Testing (TINA-CAT) workgroup has done work on a functionality centric concept called RP-facets. This report proposes a redefinition of RP-facets, as Facets, for software re-use across the design and code level. We redefine Facets as functionality centric reusable components. A Facet is independent of the implementation language and the execution platform. Facets allow containment in a structured manner via a user defined Facet Hierarchy. Facets are resource, context and data agnostic. They also introduce a structured way to allow source code to be changed based on design level decisions. Also, possessing the ability to allow the simultaneous use of other reuse solutions and programming paradigms. Abstraction of detail from developers and platform migration can be achieved by using Facets. Facets are composed of a Generic definition and any number of Implementation definitions. The definitions are supported by an underlying informational model called meta-¼. Meta- ¼ is a model at the M3 meta-level that focuses on describing entities. Most of the Facet’s capabilities are enabled by the meta-¼ model. An environment for developing Facets is created, called the Facet Development Environment (FDE). The Facet Developer (FD) role is introduced to develop and maintain Facets. The FD verifies programmes from programmers to be included into the catalogue of Facets via the FDE. The FD interacts with service creation teams to determine which Facets can be used in the service they wish to develop. Facets prove their capability in targeted areas, yet lack in other categories. It is recommended that the underlying informational model should be revised to form a more robust and flexible entity describing model. In addition, a cataloging capability to easily find Facets with particular functionality should be appended to the capabilities of the facet. It is proposed, for future work, that a development environment be created that encompasses a process for using Facets to create services.

Dagens system har blivit allt mer komplexa och därmed även processen att utveckla systemen. Det finns många olika tillvägagångssätt för systemutvecklare att arbeta och flera olika verktyg att använda sig av. Den utvecklingsmiljö en utvecklare använder sig av kan därmed ha en påverkan på hur utvecklingsprocessen ser ut. Utvecklingsmiljön är ett viktigt verktyg i dagens utvecklande samhälle och vilka för- och nackdelar olika verktyg för med sig diskuteras flitigt mellan utvecklare på olika nätforum. Från dessa forum framkommer det att vissa utvecklare föredrar att använda textredigerare istället för integrerade utvecklingsmiljöer och vice versa. Tidigare forskning har exempelvis undersökt hur kännedom kring verktyg sprids effektivt mellan utvecklare (Murphy-Hill &amp; Murphy, 2011), men denna uppsats syftar till att förklara varför utvecklare använder olika utvecklingsmiljöer och bakomliggande faktorer till detta. För att åstadkomma detta har respondenter med bred kunskap inom ämnet intervjuats och nämnt faktorer som påverkat deras val av utvecklingsverktyg. Samtliga intervjupersoner har arbetat i både integrerade utvecklingsmiljöer och textredigerare och har därmed åsikter om båda miljöerna. Enligt vår studie finns inga tydliga indikeringar för vilken utvecklingsmiljö som är att föredra i alla lägen. En utvecklare använder det verktyg som passar dess arbetsprocess bäst, men kan ibland använda andra verktyg för att komplettera sin verktygslåda. Vad som styr utvecklaren har att göra med personliga preferenser, hur utvecklaren har påverkats av utbildning och erfarenheter samt potentiella restriktioner inom organisationer. / Today's systems have become more complex and thus the process of developing systems. There are many different approaches for developers to work and several tools that can be used. The environment a developer uses can therefore have an impact on how the development process proceeds. The development environment is an essential tool in today’s evolving society, and what advantages and disadvantages different tools bring are being discussed frequently between developers on various online forums. From these forums, it appears that some developers prefer to use text editors instead of integrated development environments and vice versa. Previous research has shown, for example, how knowledge about the tools is spread effectively between developers (Murphy Hill &amp; Murphy, 2011). But this paper seeks to explain why developers are using different development environments and the factors behind this. To achieve this, we interviewed respondents with broad knowledge about the subject that stated the factors that influenced their choice of development tools. All the interviewees have worked in both integrated development environments and text editors and therefore have opinions about both environments. According to our study, there are no clear indications that a specific development environment is preferred in all situations. A developer is using the tool that fits their work process best, but sometimes uses other tools to complement their toolbox. In choosing a tool the developer is influenced by personal preferences, how surroundings have influenced the developer through education and experience, and potential constraints within organizations.

Le développement du logiciel actuel doit faire face de plus en plus à la complexité de programmes gigantesques, élaborés et maintenus par de grandes équipes réparties dans divers lieux. Dans ses tâches régulières, chaque intervenant peut avoir à répondre à des questions variées en tirant des informations de sources diverses. Pour améliorer le rendement global du développement, nous proposons d'intégrer dans un IDE populaire (Eclipse) notre nouvel outil de visualisation (VERSO) qui calcule, organise, affiche et permet de naviguer dans les informations de façon cohérente, efficace et intuitive, afin de bénéficier du système visuel humain dans l'exploration de données variées. Nous proposons une structuration des informations selon trois axes : (1) le contexte (qualité, contrôle de version, bogues, etc.) détermine le type des informations ; (2) le niveau de granularité (ligne de code, méthode, classe, paquetage) dérive les informations au niveau de détails adéquat ; et (3) l'évolution extrait les informations de la version du logiciel désirée. Chaque vue du logiciel correspond à une coordonnée discrète selon ces trois axes, et nous portons une attention toute particulière à la cohérence en naviguant entre des vues adjacentes seulement, et ce, afin de diminuer la charge cognitive de recherches pour répondre aux questions des utilisateurs. Deux expériences valident l'intérêt de notre approche intégrée dans des tâches représentatives. Elles permettent de croire qu'un accès à diverses informations présentées de façon graphique et cohérente devrait grandement aider le développement du logiciel contemporain. / Nowadays, software development has to deal more and more with huge complex programs, constructed and maintained by large teams working in different locations. During their daily tasks, each developer may have to answer varied questions using information coming from different sources. In order to improve global performance during software development, we propose to integrate into a popular integrated development environment (Eclipse) our new visualization tool (VERSO), which computes, organizes, displays and allows navigation through information in a coherent, effective, and intuitive way in order to benefit from the human visual system when exploring complex data. We propose to structure information along three axes: (1) context (quality, version control, etc.) determines the type of information; (2) granularity level (code line, method, class, and package) determines the appropriate level of detail; and (3) evolution extracts information from the desired software version. Each software view corresponds to a discrete coordinate according to these three axes. Coherence is maintained by navigating only between adjacent views, which reduces cognitive effort as users search information to answer their questions. Two experiments involving representative tasks have validated the utility of our integrated approach. The results lead us to believe that an access to varied information represented graphically and coherently should be highly beneficial to the development of modern software.
