Neste sentido, a interoperabilidade pragmática tem se destacado como um requisito fundamental para garantir a colaboração em sistemas distribuídos. Entretanto, preencher este requisito não é uma tarefa trivial. O objetivo deste estudo é propor e avaliar uma solução para apoiar implementação da interoperabilidade pragmática em um sistema colaborativo. Assim, a solução proposta foi implementada e avaliada em um ecossistema de software baseado na web capaz de apoiar o desenvolvimento colaborativo de workflows científicos chamado ECOS Collaborative PL-Science. / Providing interoperability support only considering the format and meaning (i.e. syn-tax and semantic) in data exchange is not enough to achieve effective and meaningful collaboration. Pragmatic interoperability has been identified as a key requirement to fos-ter collaboration in a distributed environment. However, fulfilling this requirement is not a trivial task. The aim of this study is to propose and evaluate a solution to support pragmatic interoperability implementation in a collaborative system. The proposed solu-tion was implemented and evaluated in an open source web-based software ecosystem to support collaborative development of scientific workflows.

O uso de aeronaves não tripuladas (VANTs) tem crescido substancialmente nos últimos anos, tanto no campo militar quanto no civil. Roadmaps preveem que em um futuro próximo essas aeronaves compartilhem o espaço aéreo com aeronaves convencionais, exigindo novas arquiteturas de sistemas embarcados que possam garantir uma operação coordenada e segura desses robôs. A maior parte das suas missões baseia-se fortemente em um conjunto de sensores transportados pela aeronave como parte da payload da missão. Contudo, não é trivial a integração de diferentes missões em diferentes aeronaves, visto que ainda não há uma padronização para a comunicação nesses robôs. Para possibilitar essa associação foi proposto neste trabalho a criação de um middleware. Para que se pudesse entender sobre a área de conhecimento dos VANTs realizou-se uma pesquisa sobre esses veículos e suas aplicações e então um protocolo chamado Smart Sensor Protocol (SSP) foi modelado, utilizando-se de técnicas formais para isso. O comportamento do protocolo está modelado com diagrama de estados, seguindo uma gramática escrita utilizando a forma BNF. Este modelo foi verificado com a ferramenta UPPAAL e sua implementação testada em placas Arduino. Os resultados dos testes mostraram que o modelo é viável para o ambiente de embarcados críticos visto que ele provê as funcionalidades necessárias neste cenário sem acrescentar um overhead na comunicação / UNMANNED Aerial Vehicles applications have grown substantially in recent years, both in military and civil fields. Roadmaps predict that in the near future these aircrafts will share the airspace with the conventional planes, requiring new architectures for embedded systems which may ensure a coordinated and safe operation. Most of its tasks are mainly based on a set of sensors carried by the aircraft as part of its payload. However, it is not trivial to integrate different missions in different aircraft plataforms, since there is no standardization for communication in such robots yet. To enable this type of association it was proposed in this masters project the designing of a middleware. It has been carried out a bibliographic review to find out the state-of-the-art in such field, including the specific applications in UAVs, and then a protocol has been modeled following formal techniques. This protocol is called Smart Sensor Protocol (SSP). The SSPs behavior was modeled through state diagrams according to a grammar described using BNF form. This model was verified with the UPPAAL tool and its implementation was run and tested on Arduino boards. The test results pointed out that the model is feasible for critical embedded environments since it provides the necessary functionality in this scenario without addition of an overhead in its communication

Uma ontologia sobre Universidade pode retratar uma instituição em particular, e ampliar a consistência e a clareza dos conceitos e propriedades do domínio. Entretanto, há necessidade de se estruturar conceitos comuns às instituições de ensino superior no Brasil para promover o intercâmbio e a integração de informações de forma a se construir um modelo de referência na área acadêmica das instituições. Esta dissertação apresenta a proposta de uma ontologia, no domínio da gestão acadêmica, denominada ontoAGA para ajudar a exploração de dados legados na web Semântica de forma padronizada e possibilitando a integração de bases de dados de diferentes tecnologias. / The evolution of the Semantic Web has encouraged the creation of ontologies in different domains and with the purpose of content interpretation according to its context. An ontology about University can describe a specific institution and consistency and clearness of concepts and domain properties. Otherwise, there is a demand to structure common concepts of higher education institutions in Brazil to promote the exchange and integration of information in order to build a reference model for educational institutions. This work presents the proposal of an ontology in the field of educational management, named ontoAGA, to help exploit legacy data in Semantic Web in a standardized manner and enable the integration of databases of different technologies.

Os padrões de interoperabilidade desempenham um papel importante na integração de sistemas e compartilhamento de informações no ambiente de governo eletrônico. Mas o desenvolvimento e estabelecimento destes padrões não dependem somente de aspectos tecnológicos. A integração de sistemas e compartilhamento de informações não significam apenas troca de dados mas, principalmente, integração de processos e transações. Neste cenário, surgem outras variáveis dos contextos institucional (organizacional e político), econômico e social. Além disso, no ambiente de governo eletrônico as transações envolvem geralmente múltiplos agentes e são condicionadas fortemente por aspectos culturais, o que torna esses processos ainda mais complexos e inter-relacionados. E mais: o estabelecimento de padrões implica reestruturação de processos de negócios e/ou mudanças na forma de interação desses agentes com as várias agências governamentais. A partir desse cenário, a presente pesquisa objetiva compreender os processos de desenvolvimento e implementação de uma arquitetura de interoperabilidade para governo eletrônico e identificar prováveis implicações da condução desses processos na posterior adoção dos padrões especificados. O objeto de estudo do é a arquitetura e-PING, um conjunto de padrões de interoperabilidade definido pelo Governo Federal brasileiro, que abrange cinco principais áreas: interconectividade, segurança, meios de acesso, organização e intercâmbio de informações. A metodologia adotada foi a do estudo de caso único longitudinal, com abordagem qualitativa, tendo como base de análise a Teoria Institucional. Foram utilizados análise documental, entrevistas semi-estruturadas para a coleta de dados. Os resultados apontam que, embora a adoção de mecanismos de isomorfismo e estratégias de legitimação possa influenciar positivamente os processos de institucionalização da arquitetura, essas ações apresentam efetividade limitada em decorrência principalmente do ambiente e do contexto onde os referidos processos ocorrem. / Interoperability standards play an important role in the integration and sharing of information in electronic government environments. The development and implementation of these standards, however, does not depend solely on technological issues. Systems integration and information sharing is not only about data exchange, but, mainly, about integration of processes and transactions. With this view, other variables from the institutional (organizational and political), economic and social context become relevant. Furthermore, in electronic government environments, transactions usually involve multiple agents and are strongly conditioned by cultural aspects, contributing to the increase of processes complexity and connectivity. The establishment of standards does also require the restructuration of business processes and changes in the way the agents interact with the various government agencies. Based on this scenario, this research aims at understanding the processes of development and implementation of architecture for electronic government interoperability and at identifying possible implications of the way in which these processes have been managed on the ensuing adoption of the specified standards. The research object is the e- PING architecture, a set of interoperability standards defined by the Brazilian Federal Government, comprising five main areas: interconnectivity, security, means for access, organization and interchange of information. Single case longitudinal study was the adopted research methodology, with a qualitative approach, using Institutional Theory as the basis for analysis. Data collection was based on document analysis, structured and semi-structured interviews. The results indicate that, although the adoption of isomorphism mechanism and legitimating strategies could contribute to the architecture\'s institutionalization, these actions have their effectiveness limited by conditions of the environment in which these processes occur.

Testing is one of the critical processes in software development life cycle. It plays key role in the success of software product by improving its quality. Web-based applications are emerging and evolving rapidly; their importance and complexity is also increasing. Heterogeneous and diverse nature of distributed components, applications; along with their multi-platform support and cooperativeness make these applications more complex and swiftly increasing in their size. Quality assurance of these applications is becoming more crucial and important; testing is one of the key processes to achieve and ensure the quality of these software or Web-based products. There are many testing challenges involved in Web-based applications. But most importantly interoperability and integration are the most critical testing challenges associated with Web-based applications. There are number of challenging factors involved in both integration and interoperability testing efforts. These integration and interoperability factors have almost 70 percent to 80 percent impact on overall quality of Web-based applications. In software industry different kind of testing approaches are used by practitioners to solve the issues associated with integration and interoperability, which are due to ever increasing complexities of Web-based applications. It is fact that both integration and interoperability are inter-related and it is very helpful to cover all the possible issues of interoperability testing that will reduce the integration testing effort. It will be more beneficial if a dedicated testing team is placed to perform the both integration and interoperability testing. / +46 73 55 955 15 +46 73 95 120 32

Middleware eases the development of distributed applications. Expansion in the enterprise world entails integration of heterogeneous products, and there is a demand for a balance between performance, interoperability and security in the distributed applications. Windows Communication Foundation (WCF) offers a technology to build service-oriented, secure, reliable and interoperable distributed applications. The current literature contains few studies comparing the performance of WCF with other technologies, but it does not address the performance of WCF in a cross-technology communication. This master thesis experimentally evaluates the performance of WCF in unsecure and secure variants. It evaluates the performance in on-machine and cross-machine communication, and it addresses the performance of WCF’s interoperability with ASMX and Java. We have developed the service and client applications in both secure and unsecure variants. The experiments are then conducted using these applications in a laboratory setting. We have measured the performance in terms of throughput, response time, processor and memory utilization during the experiments. Our results show that in unsecure variants, the WCF service in cross-machine communication has the best response time than on-machine communication on small datasets. However, on large datasets the service in on-machine communication has the best response time. In secure variants, the service in on-machine communication has better response time than the cross-machine communication. In both secure and unsecure variants, the service has better throughput and consumed lesser resources in cross-machine communication than in on-machine communication. In case of WCF’s interoperability with ASMX and Java, both the secure as well as unsecure WCF service show more scalable performance for the WCF client than for ASMX and Java clients. The secure as well as unsecure service show better performance for the ASMX client than for the Java client. The unsecure variants of WCF service perform better than the secure variants, except in a few cases of memory utilization. Therefore, the performance of the WCF service degrades due to security.

The term “Internet of Things” (IoT) was first introduced by a technology pioneer Kevin Ashton in 1999.Although the term is relatively new, the idea of making networks and computers communicate in order totrack and manage devices has been around for many years. As of now IoT is a rising topic in technicalcommunity. Some specialists are anticipating that by 2025 there will be around 100 billion connected IoTdevices with a worldwide economic impact of more than $11 trillion. On the other hand, Internet of Thingsemerges significant challenges. Currently the organization around world use two main approaches whenentering the IoT market. First one is an open platform and is represented by interoperability andcollaboration with devices from different vendors. Second one is a closed platform, or a “walled garden”approach. A “walled garden” approach is characterized by building “fences” around the user. In other words,the service provider has control over applications, content and media and also restricts the non-approvedcontent to reach the customer. Therefore, the research set out to explore these approaches and show thebenefits and limits they can have on an organization. The research was conducted in collaboration with aSwedish manufacturer of outdoor power products called Husqvarna Group. In order to fully acknowledgethe organization’s approach, 4 interviews were conducted with managers, back end developers andconsultants hired by Husqvarna Group. From the findings, some things should be taken in consideration.First, IoT involves big data being collected, therefore security and privacy are crucial when developingdevices and systems. Second, it is essential for an organization to have the same views when taking a newdirection. Third, when discussing Internet of Things, it means that things connect, devices to sensors,sensor to gateways and gateways to system. And there shouldn’t be a delimitation from a vendor to another.Therefore, open platform approach is seen as the way to diversity and innovation.

Our ultimate goal as obstetric and neonatal care providers is to improve care for mothers and their babies. Continuous quality improvement (CQI) involves iterative cycles of practice change and audit of ongoing clinical care identifying practices that are associated with good outcomes. A vital prerequisite to this evidence based medicine is data collection. In Canada, much of the country is covered by separate fragmented silos known as regional reproductive care databases or perinatal health programs. A more centralized system which includes collaborative efforts is required. Moving in this direction would serve many purposes: efficiency, economy in the setting of limited resources and shrinking budgets and lastly, interaction among data collection agencies. This interaction may facilitate translation and transfer of knowledge to care-givers and patients. There are however many barriers towards such collaborative efforts including privacy, ownership and the standardization of both digital technologies and semantics. After thoroughly examining the current existing perinatal data collection among Perinatal Health Programs (PHPs), and the Canadian Perinatal Network (CPN) database, it was evident that there is little standardization of definitions. This serves as one of the most important barriers towards data sharing. To communicate effectively and share data, researchers and clinicians alike must construct a common perinatal language. Communicative tools and programs such as SNOMED CT® offer a potential solution, but still require much work due to their infancy. A standardized perinatal language would not only lay the definitional foundation in women’s health and obstetrics but also serve as a major contribution towards a universal electronic health record. / Medicine, Faculty of / Obstetrics and Gynaecology, Department of / Graduate

In order to develop and secure the functionality of its cellular communications systems, Ericsson deals with numerous R&D and I&V activities. One important aspect is interoperability with mobile terminals from different vendors on the world market. Therefore Ericsson co-operates with mobile platform and user equipment manufacturers. These companies visit the interoperability developmental testing (IoDT) laboratories in Linköping to test their developmental products and prototypes in order to certify compliance with Ericsson's products. The knowledge exchange is mutual, Ericsson as well as the user equipment manufacturers benefit from the co-operation. The goal of this master's thesis performed at Ericsson AB is to suggest areas in which the IoDT testing can be automated in order to minimize time consuming and tedious work tasks. Primarily the search should be aimed at replacing manual tasks in use today. The thesis suggests a number of IoDT tasks that might be subject for automation. Among these one is chosen for implementation. The thesis also includes an implementation part. The task that has been chosen for implementation is the network verification after base station controller software upgrade procedure. This is not a core IoDT function but it implies a lot of work, and is often performed. The automation project is also supposed to act as a springboard for future automation within IoDT. The forthcoming LTE standard will require a lot of IoDT testing, and therefore the automation capabilities should be investigated. The thesis shows that automation work is possible, and that the startup process is straightforward. Existing tools are easy to use, and well supported. The network verification automated test scope has been successful.

In silico experiments in the field of bioinformatics generate large amounts of data since most of the tasks are done in an exploratory fashion. Workflows are one of the many tools used by scientists to model complex tasks.The interoperability of data generated from these tools plays an important role in improving the efficiency of such tools and also in verifying results from other experiments.We aim to compare workflow systems by integrating bioinformatics data in Vistrails and Taverna. We also look at how the two systems use the open provenance model that has been developed to bring provenance interoperability. We developed web services to perform similar functions of some workflows in Vistrails. With the services we were able to perform most of the tasks we planned using both systems. Differences in how lists of items are processed in the two systems results in differences in how workflows are composed in the two systems. In Taverna there is implicit iteration and Vistrails requires the use of additional modules to perform iteration.There are also differences in the execution times of workflows using web services, with workflows in Taverna taking longer than their counterparts in Vistrails. There are some similarities in the execution pattern of workflows if same workflow is invokedmultiple times, with the first invocation taking longer time than the subsequent ones.
