En applikationsinfrastruktur för massutskick av e-post

In today's society it is becoming more and more important with direct marketing. Some of the direct marketing is done through e-mail, in which companies see an easy way to advertise himself. I did this thesis work at WebDoc Systems. They have a product that creates web documents directly in your browser, also called CMS. The CMS has a module for sending mass e-mail, but this module does not function properly and WebDoc Systems customers are dissatisfied with that part of the product. The problem with the module was that sometimes it didn't send the e-mail, and that it was not possible to obtain some form of follow-up information on the e-mail. The goal of this work was to develop a Web service that could easily send e-mail to many receivers, just as easily be able to view statistics on how mailing has gone. The first step was to do a literature review to get a good picture of available programming platforms, but also to be able create a good application infrastructure. The next step was to implement this design and improve it over time by using an iterative development methodology. The result was an application infrastructure that consists of three main parts and a plugin interface. The parts that were implemented were a Web service application, a Web application and a Windows service application. The three elements cooperate with each other and share a database, and plugins.

En utvärdering av Android och Iphone : För utveckling av webbtjänstunderstödda applikationer ämnade för intern distribution

Tack vare bättre och bättre förutsättningar för utveckling av mobila applikationer, samt utbredning av internetbaserade tjänster, presenteras här ett underlag inför val av mobil utvecklingsplattform. De undersökta plattformarna är Android och Iphone på grund av deras växande utbredning på smartphonemarknaden. Studien presenterar förutsättningar för att utveckla webbtjänst-understödda applikationer för intern distribuering. Ett visuellt tilltalande användargränssnitt är också i fokus för den typen av applikation studien riktar sig mot.Vi har kommit fram till att Android är lättare att lära sig om man kommer ifrån en Java- eller .Netmiljö samt lättare att distribuera. Iphone har däremot bättre stöd för att utveckla grafiskt tilltalande applikationer. Båda plattformarna har dock bristfälligt stöd för kommunikation via webbtjänster. Detta resultat uppnåddes genom litteraturstudier, samt en fallstudie där vi utvecklade applikationer med fokus på just webbtjänstkommunikation, intern distribuering samt ett tilltalande användargränssnitt.

Firmament : um módulo de injeção de falhas de comunicação para linux

A execução de testes é um passo essencial na adoção de novos protocolos de comunicação e sistemas distribuídos. A forma com que estes se comportam na presença de falhas, tão comuns em ambientes geograficamente distribuídos, deve ser conhecida e considerada. Testes sob condições de falha devem ser realizados e as implementações devem trabalhar dentro de sua especificação nestas condições, garantindo explicitamente o funcionamento dos seus mecanismos de detecção e recuperação de erros. Para a realização de tais testes, uma técnica poderosa é a injeção de falhas. Ferramentas de injeção de falhas permitem ao projetista ou engenheiro de testes medir a eficiência dos mecanismos de um sistema antes que o mesmo seja colocado em operação efetiva. Este trabalho apresenta o projeto, desenvolvimento e teste do injetor de falhas FIRMAMENT. Esta ferramenta executa, dentro do núcleo do sistema operacional, microprogramas, ou faultlets, sobre cada mensagem processada para a emulação de situações de falha de comunicação, utilizando uma abordagem de scripts. A ferramenta é implementada como um módulo de núcleo do sistema operacional Linux, tendo acesso total aos fluxos de entrada e saída de pacotes de forma limpa e não intrusiva, permitindo o teste de sistemas baseados nos protocolos IPv4 e IPv6. Seu desempenho é significativo, já que a ferramenta evita que os mecanismos de injeção de falhas sejam invocados nos fluxos que não sejam de interesse aos testes, bem como dispensa a cópia de dados dos pacotes de comunicação a serem inspecionados e manipulados. A aplicabilidade da ferramenta, dada pela sua facilidade de integração a um ambiente de produção, é conseqüência de sua disponibilidade como um módulo de núcleo, podendo ser carregada como um plugin em um núcleo não modificado. As instruções por FIRMAMENT suportadas lhe dão alto poder de expressão dos cenários de falhas. Estas instruções permitem a inspeção e seleção de mensagens de forma determinística ou estatística. Além disso, fornecem diversas ações a serem realizadas sobre os pacotes de comunicação e sobre as variáveis internas do injetor, fazendo-o imitar o comportamento de falhas reais, como descarte e duplicação de mensagens, atraso na sua entrega e modificação de seu conteúdo. Estas características tornam a ferramenta apropriada para a realização de experimentos sobre protocolos e sistemas distribuídos.

De touch: extending service channels in an airport through touch technologies

This project aimed to create a communication and interaction channel between Madeira Airport and its passengers. We used the pre-existent touch enabled screens at the terminal since their potential was not being utilised to their full capacity. To achieve our goal, we have followed an agile strategy to create a testable prototype and take advantages of its results. The developed prototype is based on a plugin architecture turning it into a maintainable and highly customisable system. The collected usage data suggests that we have achieved the initially defined goals. There is no doubt that this new interaction channel is an improvement regarding the provided services and, supported by the usage data, there is an opportunity to explore additional developments to the channel.

Desenvolvimento de um sistema para aplicação dos conceitos da tecnologia cad3d-bim na indústria moveleira

In this work was developed an information system to apply the concepts of CAD3D-BIM technology for the design activities of the furniture industry. The development of this system was based in an architecture comprised of two modules: a web interface to management the metadata of models from furniture's library and the combination of three-dimensional CAD software with a specific plugin to access the information from this model. To develop this system was also used a Data Base Management System (DBMS) designed to storage the information from models in a hierarchical way, based on concepts of Group Technology (GT). The centralization of information in a single database allows the automatic availability of any changes to all participants involved in a particular project when it‟s happens. Each module from system has its own connection to this database. Finally was developed a prototype from a 3D virtual environment to help create Virtual Reality projects in the web. A study from available technologies to create 3D web applications for execution in websites was done to support this development. The interconnection between modules and the database developed allowed the assembly of a system architecture to support the construction and exhibition of projects of the furniture industry in accordance with the concepts proposed by BIM (Building Information Modeling), using as object of study the furniture industry of state of Rio Grande do Norte

Determinacão do período orbital de sistemas binários clipsantes

In this work is presented a new method for the determination of the orbital period (Porb) of eclipsing binary systems based on the wavelet technique. This method is applied on 18 eclipsing binary systems detected by the CoRoT (Convection Rotation and planetary transits) satellite. The periods obtained by wavelet were compared with those obtained by the conventional methods: box Fitting (EEBLS) for detached and semi-detached eclipsing binaries; and polynomial methods (ANOVA) for contact binary systems. Comparing the phase diagrams obtained by the different techniques the wavelet method determine better Porb compared with EEBLS. In the case of contact binary systems the wavelet method shows most of the times better results than the ANOVA method but when the number of data per orbital cicle is small ANOVA gives more accurate results. Thus, the wavelet technique seems to be a great tool for the analysis of data with the quality and precision given by CoRoT and the incoming photometric missions.

Uma linguagem de modelagem da interação para auxiliar a comunicação designer-usuário

The development of interactive systems involves several professionals and the integration between them normally uses common artifacts, such as models, that drive the development process. In the model-driven development approach, the interaction model is an artifact that includes the most of the aspects related to what and how the user can do while he/she interacting with the system. Furthermore, the interactive model may be used to identify usability problems at design time. Therefore, the central problematic addressed by this thesis is twofold. In the first place, the interaction modeling, in a perspective that helps the designer to explicit to developer, who will implement the interface, the aspcts related to the interaction process. In the second place, the anticipated identification of usability problems, that aims to reduce the application final costs. To achieve these goals, this work presents (i) the ALaDIM language, that aims to help the designer on the conception, representation and validation of his interactive message models; (ii) the ALaDIM editor, which was built using the EMF (Eclipse Modeling Framework) and its standardized technologies by OMG (Object Management Group); and (iii) the ALaDIM inspection method, which allows the anticipated identification of usability problems using ALaDIM models. ALaDIM language and editor were respectively specified and implemented using the OMG standards and they can be used in MDA (Model Driven Architecture) activities. Beyond that, we evaluated both ALaDIM language and editor using a CDN (Cognitive Dimensions of Notations) analysis. Finally, this work reports an experiment that validated the ALaDIM inspection method

MARISA-MDD: uma abordagem para transformações entre modelos orientados a aspectos: dos requisitos ao projeto detalhado

Aspect Oriented approaches associated to different activities of the software development process are, in general, independent and their models and artifacts are not aligned and inserted in a coherent process. In the model driven development, the various models and the correspondence between them are rigorously specified. With the integration of aspect oriented software development (DSOA) and model driven development (MDD) it is possible to automatically propagate models from one activity to another, avoiding the loss of information and important decisions established in each activity. This work presents MARISA-MDD, a strategy based on models that integrate aspect-oriented requirements, architecture and detailed design, using the languages AOV-graph, AspectualACME and aSideML, respectively. MARISA-MDD defines, for each activity, representative models (and corresponding metamodels) and a number of transformations between the models of each language. These transformations have been specified and implemented in ATL (Atlas Definition Language), in the Eclipse environment. MARISA-MDD allows the automatic propagation between AOV-graph, AspectualACME, and aSideML models. To validate the proposed approach two case studies, the Health Watcher and the Mobile Media have been used in the MARISA-MDD environment for the automatic generation of AspectualACME and aSideML models, from the AOV-graph model

Uma abordagem dirigida por modelos para gerência de variabilidade e execução de processos de software

This dissertation presents a model-driven and integrated approach to variability management, customization and execution of software processes. Our approach is founded on the principles and techniques of software product lines and model-driven engineering. Model-driven engineering provides support to the specification of software processes and their transformation to workflow specifications. Software product lines techniques allows the automatic variability management of process elements and fragments. Additionally, in our approach, workflow technologies enable the process execution in workflow engines. In order to evaluate the approach feasibility, we have implemented it using existing model-driven engineering technologies. The software processes are specified using Eclipse Process Framework (EPF). The automatic variability management of software processes has been implemented as an extension of an existing product derivation tool. Finally, ATL and Acceleo transformation languages are adopted to transform EPF process to jPDL workflow language specifications in order to enable the deployment and execution of software processes in the JBoss BPM workflow engine. The approach is evaluated through the modeling and modularization of the project management discipline of the Open Unified Process (OpenUP)

Um modelo conceitual baseado em MDD e padrões para evolução de sistemas OA

Aspect-Oriented Software Development (AOSD) is a technique that complements the Object- Oriented Software Development (OOSD) modularizing several concepts that OOSD approaches do not modularize appropriately. However, the current state-of-the art on AOSD suffers with software evolution, mainly because aspect definition can stop to work correctly when base elements evolve. A promising approach to deal with that problem is the definition of model-based pointcuts, where pointcuts are defined based on a conceptual model. That strategy makes pointcut less prone to software evolution than model-base elements. Based on that strategy, this work defines a conceptual model at high abstraction level where we can specify software patterns and architectures that through Model Driven Development techniques they can be instantiated and composed in architecture description language that allows aspect modeling at architecture level. Our MDD approach allows propagate concepts in architecture level to another abstraction levels (design level, for example) through MDA transformation rules. Also, this work shows a plug-in implemented to Eclipse platform called AOADLwithCM. That plug-in was created to support our development process. The AOADLwithCM plug-in was used to describe a case study based on MobileMedia System. MobileMedia case study shows step-by-step how the Conceptual Model approach could minimize Pointcut Fragile Problems, due to software evolution. MobileMedia case study was used as input to analyses evolutions on software according to software metrics proposed by KHATCHADOURIAN, GREENWOOD and RASHID. Also, we analyze how evolution in base model could affect maintenance on aspectual model with and without Conceptual Model approaches

Dos requisitos à arquitetura em linhas de produtos de software: uma estratégia de transformações entre modelos

The tracking between models of the requirements and architecture activities is a strategy that aims to prevent loss of information, reducing the gap between these two initial activities of the software life cycle. In the context of Software Product Lines (SPL), it is important to have this support, which allows the correspondence between this two activities, with management of variability. In order to address this issue, this paper presents a process of bidirectional mapping, defining transformation rules between elements of a goaloriented requirements model (described in PL-AOVgraph) and elements of an architectural description (defined in PL-AspectualACME). These mapping rules are evaluated using a case study: the GingaForAll LPS. To automate this transformation, we developed the MaRiPLA tool (Mapping Requirements to Product Line Architecture), through MDD techniques (Modeldriven Development), including Atlas Transformation Language (ATL) with specification of Ecore metamodels jointly with Xtext , a DSL definition framework, and Acceleo, a code generation tool, in Eclipse environment. Finally, the generated models are evaluated based on quality attributes such as variability, derivability, reusability, correctness, traceability, completeness, evolvability and maintainability, extracted from the CAFÉ Quality Model

Apoiando a Construcao de Testes de Aceitacao Automatizados a partir da Especificacao de Requisitos

A automação consiste em uma importante atividade do processo de teste e é capaz de reduzir significativamente o tempo e custo do desenvolvimento. Algumas ferramentas tem sido propostas para automatizar a realização de testes de aceitação em aplicações Web. Contudo, grande parte delas apresenta limitações importantes tais como necessidade de valoração manual dos casos de testes, refatoração do código gerado e forte dependência com a estrutura das páginas HTML. Neste trabalho, apresentamos uma linguagem de especificação de teste e uma ferramenta concebidas para minimizar os impactos propiciados por essas limitações. A linguagem proposta dá suporte aos critérios de classes de equivalência e a ferramenta, desenvolvida sob a forma de um plug-in para a plataforma Eclipse, permite a geração de casos de teste através de diferentes estratégias de combinação. Para realizar a avaliação da abordagem, utilizamos um dos módulos do Sistema Unificado de Administração Publica (SUAP) do Instituto Federal do Rio Grande do Norte (IFRN). Participaram da avaliação analistas de sistemas e um técnico de informática que atuam como desenvolvedores do sistema utilizado.

Effect of thermocycling on the flexural and impact strength of urethane-based and high-impact denture base resins

Objective: Mechanical properties of the acrylic resins used for denture fabrication may be influenced by water and temperature. Thus, the aim of this study was to evaluate the effect of thermocycling on the flexural and impact strength of a high-impact (Lucitone 199) and a urethane-based denture material (Eclipse).Materials and methods: Flexural strength (64 x 10 x 3.3 mm) and impact strength (60 x 6 x 4 mm) specimens were made following the manufacturers' instructions and assigned to two groups (n = 10): control (C) - not thermocycled - and T - thermocycled (5000 cycles between 5 and 55 degrees C). Specimens were submitted to three-point bending and Charpy impact tests.Results: Flexural strength (MPa) and impact strength (kJ/m(2)) data were analysed with two-way ANOVA (p = 0.05). The flexural strength of material Eclipse (C, 136.5; T, 130.7) was significantly higher than that of resin Lucitone 550 (C, 99.4; T, 90.1). Material Eclipse exhibited significantly higher impact strength (C, 6.9; T, 5.3) than the resin Lucitone 550 (C, 3.5; T, 3.0). For both materials, a significant decrease in flexural and impact strengths was observed when the specimens were thermocycled.Conclusion: Flexural and impact strengths were higher for Eclipse than for Lucitone 550, in both groups. Thermocycling decreased the flexural and impact strengths of Eclipse and Lucitone 550.
