SOFA 2 is a component system employing hierarchically composed components. It provides ADL-based design, behavior specification using behavior protocols, dynamic reconfiguration of the components, and modeling of the component communication by software connectors. This allows seamless and transparent distribution of component applications. The connectors can be automatically generated, SOFA 2 contains Java connector generator allowing to connect components with Java interfaces. The aim of this thesis is to implement C code generator and integrate it into the current SOFA 2 connector generator framework, so that C connectors can be automatically generated and thus components written in C language can be transparently connected in distributed environment. The proposed C code generator is based on the concept of template transformation, where templates containing mixture of C code and a scripting Domain Specific Language are transformed to a pure C code. Strategic term rewriting method provided by Stratego/XT framework is used for evaluation of the scripts within the templates.

Random variate genration is an important tool in statistical computing. Many programms for simulation or statistical computing (e.g. R) provide a collection of random variate generators for many standard distributions. However, as statistical modeling has become more sophisticated there is demand for larger classes of distributions. Adding generators for newly required distribution seems not to be the solution to this problem. Instead so called automatic (or black-box) methods have been developed in the last decade for sampling from fairly large classes of distributions with a single piece of code. For such algorithms a data about the distributions must be given; typically the density function (or probability mass function), and (maybe) the (approximate) location of the mode. In this contribution we show how such algorithms work and suggest an interface for R as an example of a statistical library.

For the training of these there is a demand for resources - human and material - which most of the time have high cost. Thus, a solution is needed as accessible to institutions and researchers, as adaptable to your needs, providing scalability and dissemination to training, without focusing on quality. From the literature, based and presenting the Ptolemy framework, developed in Java and that allows the simulation of concurrent and heterogeneous systems, and in the Actor Model were directed efforts for the development of a tool for code generation open-source and multiplatform. Thus, the aim of this work is to develop a tool to generate VHDL code based on Ptolemy Actors using the Ptolemy framework. Where, in addition to design and simulate graphically there is a difference in the possibility of modeling at different levels of abstraction and generation of the VHDL code in a hierarchical manner, presenting the process of development of the tool and the results of its use, as well as contributions. / Na área de Microeletrônica uma das maiores dificuldades trata-se de encontrar profissionais capacitados. Para a formação destes há uma demanda por recursos humanos e materiais - que, muitas vezes, tem alto custo. Assim, se faz necessária uma solução tão acessível a instituições e pesquisadores, quanto adaptável às suas necessidades, propiciando escalabilidade e disseminação à formação, sem deixar de focar a qualidade. A partir do levantamento bibliográfico, baseando-se e apresentando o framework Ptolemy, desenvolvido em Java e que possibilita a simulação de sistemas concorrentes e heterogêneos, e no modelo de atores foram direcionados os esforços para o desenvolvimento de uma ferramenta de geração de código open-source e multiplataforma. Sendo assim, o objetivo deste trabalho é o desenvolvimento de uma ferramenta de geração de código VHDL baseada em Atores utilizando o Framework Ptolemy. Onde, além de projetar e simular graficamente há um diferencial na possibilidade de modelagem em níveis diferentes de abstração e geração de código VHDL de forma hierárquica. Apresentado o processo de desenvolvimento da ferramenta e resultados de sua utilização, bem como as contribuições.

Approved for public release, distribution is unlimited / The focus of this thesis is to use and leverage the strengths of dynamic computer program analysis methodologies in software engineering testing and debugging such as program behavior modeling and event grammars to automate the building and analysis of combat simulations. An original high level language METALS (Meta-Language for Combat Simulations) and its associated parser and C++ code generator were designed to reduce the amount of time and developmental efforts needed to build sophisticated real world combat simulations. A C++ simulation of the Navy's current mine avoidance problem in littoral waters was generated using high level METALS description in the thesis as a demonstration. The software tools that were developed will allow users to focus their attention and efforts in the problem domain while sparing them to a considerable extent the rigors of detailed implementation. / Major, Republic of Singapore Navy

A indústria de desenvolvimento de software está em constante evolução e em busca de novos desafios, como por exemplo: novas tecnologias, linguagens de programação e estratégias para aumentar a produtividade no desenvolvimento. Com o passar do tempo, essa evolução desejada tem se concretizado, em especial com o surgimento de conceitos como Service Oriented Architecture (SOA) e Model-Driven Development (MDD). Nesse contexto, ganha importância a reutilização de software, por exemplo por meio do uso de serviços que facilitam a interoperabilidade entre diferentes sistemas. Ambientes de desenvolvimento de software, em especial ambientes de reúso de software, poderiam se adequar à arquitetura SOA para facilitar a disponibilização de serviços a outros ambientes, promovendo sua integração e aumentando a possibilidade de reúso. Após um levantamento bibliográfico sobre ambientes integrados de reúso que utilizassem serviços para permitir o compartilhamento de recursos, percebeu-se que os trabalhos nessa direção são poucos. Ao mesmo tempo, observou-se que para integração de sistemas por meio de serviços é necessário criar camadas de acesso às entidades dos sistemas que compartilharão informações. A implementação desses serviços de forma manual é repetitiva e sujeita a erros, principalmente por programadores que não estão familiarizados com SOA. Por outro lado, diagramas de classes em UML (Unified Modeling Language) são de amplo conhecimento por parte de desenvolvedores e estão em um nível de abstração que é suficientemente detalhado para permitir a derivação de serviços de acesso às suas classes. Desta forma, para atender uma demanda crescente de sistemas que precisam oferecer serviços para possibilitar sua integração com outros sistemas, este mestrado tem por objetivo promover a geração automatizada de código de serviços por meio de transformações de modelo para texto, em que o modelo de entrada é um diagrama de classes derivado da UML e os serviços gerados cobrem operações básicas do tipo CRUD. O gerador resultante foi validado por meio de duas provas de conceito e mostrou-se adequado para cumprir os objetivos estabelecidos, visto que o desenvolvedor trabalha com um modelo em alto nível de abstração, não precisando conhecer os detalhes inerentes à implementação dos serviços. / The software development industry is constantly evolving and looking for challenges, such as: new technologies, programming languages and strategies to increase developers productivity. During the course of time, this required evolution has been concretized, especially with the emergency of concepts such as Service Oriented Architecture (SOA) and Model-Driven Development (MDD). In this context, software reuse gains importance, for example through the use of services that ease the interoperability of different systems. Software development environments, in special reuse environments, could be adapted to the SOA architecture to ease the availability of services to other environments, thus promoting its integration and possibility of reuse. After a literature review about integrated reuse environments that use services to allow resources sharing, it has been observed that there are only a few works in this direction. At the same time, it was observed that for system integration through services it is required to create an access layer for the system entities that share information. The manual implementation of these services is repetitive and error prone, especially for programmers who are not familiar with SOA. On the other hand, UML (Unified Modeling Language) class diagrams are widely known by developers and are at a level of abstraction that is sufficiently detailed to allow the derivation of access services to their classes. Thus, to meet a growing demand for systems that need to provide services to enable its integration with other systems, this masters dissertation aims to promote the automated generation of service code through transformations from model to text, where the input model is a class diagram derived from UML, and the generated services cover the basic CRUD operations. The resulting generator has been validated through two proofs of concepts and was adequate to meet the stated objectives, as the developer works with a model in a high abstraction level, and does not need to know the details related with the service implementation.

Os geradores de aplicação são ferramentas que recebem uma especificação de software, validam essa especificação e geram artefatos automaticamente. Os geradores de aplicação podem trazer benefícios em termos de produtividade por gerarem automaticamente artefatos de baixo nível com base em especificações de nível mais alto. Um dos problemas dos geradores de aplicação é o seu alto custo de desenvolvimento. Os geradores de aplicação configuráveis são adaptados para fornecer apoio em domínios específicos, ou seja, são considerados meta-geradores utilizados para obter geradores de aplicação específicos. Este trabalho delineia um processo de desenvolvimento com geradores confi- guráveis, define a arquitetura e as características de um gerador configurável e apresenta a ferramenta Captor, que é um gerador de aplicação configurável desenvolvido para facilitar a construção de geradores específicos. Três estudos de caso nos quais a Captor é configurada para domínios de aplicação específi- cos são apresentados: persistência de dados, gestão de recursos de negócios e bóias náuticas / Application generators are tools that receive as input a software specification, validate it and automatically generate artifacts based on it. Application generators can bring several benefits in terms of productivity, as they automatically generate low-level artifacts based on higher abstraction level specifications. A major concern of application generators is their high development cost. Con- figurable application generators are those generators that can be adapted to give support in specific domains, i.e., they are considered as meta-generators through which it is possible to obtain specific application generators. This work presents an approach for software development supported by configurable application generators. It defines the architecture and main features of a configurable application generator and presents Captor, which is a configurable application generator developed to ease the creation of specific generators. Three case studies were conducted to show the configuration of the Captor tool to different application domains: objects persistence, business resource management and floating weather stations.

Tools, which increase an engineer s productivity and minimize cost, can be considered as a competitive edge. The objective of this thesis was to design, create, and implement Automatic PLC Code Generator (APCG) software. A secondary objective was to demonstrate that the use of the APCG software will lead to improved project efficiency and enhanced profit margin. To create the APCG software, the MS Excel and Visual Basic for Applications (VBA) programs were used as the platform. MS Excel sheets were used as a user interface, while VBA creates the PLC code from the information entered by the engineer. The PLC code, created by the APCG software, follows the PLC structure of the Realcold Milmech Pty. Ltd, as well as the research Automatic generation of PLC code beyond the nominal sequence written by Guttel et al [1]. The APCG software was used to design and create a PLC code for one of the projects undertaken by Realcold Milmech Pty. Ltd. By using APCG software, time to design, create, and test the PLC code was improved when compared to the budgeted time. In addition, the project's profit margin was increased. Based on the results of this thesis it is expected that the APCG software will be useful for programmers that tend to handle a variety of projects on a regular basis, where programming in a modular way is not appropriate.

No. of bitstreams: 1 DissBFA.pdf: 12687971 bytes, checksum: 19789fb95e5c01987f5067e083d04248 (MD5) Previous issue date: 2016-03-08 / Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES) / Model-Driven Development (MDD) is proposed to reduce the semantic gap between problem and solution/implementation domains. Some tools are used, and the code generator is commonly used in this context. These generators are often implemented using templates. A Reference Implementation (RI) favoring the development/ maintenance of software facilitates this implementation’s types. However, RI requires a code migration process which consists in artifacts’ synchronization, and it is responsible for 20% to 25% of the time spent on development. The literature has no describe automatic solutions, but the group that this reaserch was included has develop tools that automate this process and reduce the time spent on some tasks. But each task has a different performance in relation to time spent, so automation of some tasks can be disadvantageous. Few reports describe such tasks and which ones are capable of automatic code migration. The aim of this study is to investigate the maintain and evolution process to identify and describe the types of maintain and evolution tasks that are essentially. Based on this study, a method (MME-MDD) that drives the developer during that proccess to guide the developer during the realization of each task, with the aim to maximize the benefits of this approach. The MME-MDD was validated by a case study and a empirical study and the method showed effective in most of tasks. In addition, studies show that using the proposed method brought a gain in the quality of the source code. / O MDD (Model-Driven Development) tem como proposta a redução da distância semântica entre os domínios problema e solução/implementação. Para isso, são utilizadas algumas ferramentas, sendo o gerador de código comumente usado neste contexto. Os geradores de código são frequentemente implementados com a utilização de templates. Para facilitar este tipo de implementação, usualmente é empregado uma Implementação de Referência (IR), favorecendo a evolução/ manutenção do software. Contudo, a IR traz a necessidade do processo de migração de código, que consiste na sincronização entre o seu código-fonte e os templates, sendo que este é responsável por 20 a 25% do tempo gasto no desenvolvimento. Na literatura não há relatos de solução automatizada, mas o grupo no qual esta pesquisa se insere vem desenvolvendo ferramentas que automatizam este processo e reduzem o tempo aplicado em algumas tarefas testadas. Porém, cada tarefa tem um desempenho diferente em relação ao tempo gasto e, portanto, a automação de algumas tarefas pode ser desvantajosa. Existem poucos relatos na literatura descrevendo tais tarefas e quais são os passos necessários para realizá-las. O objetivo deste estudo foi a investigação do processo de manutenção e evolução de sistemas baseados em MDD com a finalidade de identificar e descrever os tipos de tarefas de manutenção e evolução. Com base nesse estudo, foi elaborado o método MMEMDD que conduz o desenvolvedor durante o processo de manutenção e evolução de sistemas, visando guiar o desenvolvedor durante a realização de cada um dos tipos de tarefas, com o intuito de maximizar os benefícios da utilização dessa abordagem. O método foi validado por meio de um estudo de caso e um estudo experimental, sendo que o método se mostrou efetivo em grande parte das tarefas testadas. Além disso, os estudos apontaram que a utilização do método proposto trouxe ganho na qualidade do código-fonte.
