The increasing complexity of embedded systems development is becoming difficult to handle with development environments based on disjoint engineering tools. Support for interactions between various engineering tools, especially through automated means, has therefore received an increased amount of attention during the last few years. The subsequent increase in the amount of tool integration is leading to an increased impact of tool integration on non-functional properties of development efforts, development environments and end products. At the same time there is a lack of methods and tools for analysing the relationship between these properties and tool integration. To establish a foundation for analysing this generic relationship, the specific relationship between tool integration and the safety of end products is analysed in this thesis. A survey was conducted to analyze the State of the Art of tool integration as related to safety. This survey specifically identified the lack of an efficient handling of tool integration by modern safety standards as an important concern. In relation to this survey, three theories were identified as of specific importance. These are the school of thought known as Systems Thinking, the Systems-Theoretic Accident Model and Processes (STAMP) causality model and the System-Theoretic Process Analysis (STPA) hazard analysis technique. Building on these theories, this thesis provides original contributions intended to (1) describe concepts and models related to tool integration and safety (the first and second contribution), (2) link tool integration to safety in a way that reduces complexity during analysis (the third contribution) and (3) propose how to interpret and make use of the implications of the presented theories and the first three contributions (the fourth and fifth contribution). • The first contribution is a new conceptual model of a development effort that emphasizes tool integration. • The second contribution is a new reference model for tool integration in highly heterogeneous environments. • The third contribution consists of nine safety-related tool chain properties, i.e. properties of tool chains that could mitigate at least part of the risks introduced by tool integration. • The fourth contribution is a proposition on how to identify safety implications due to a high level of automation of tool integration. • The fifth contribution is a proposition for a new software tool qualification process.

This master's thesis explores the effectiveness of an educational intervention using an interactive notebook to support and supplement instruction in a foundational-level programming course. A quantitative, quasi-experimental group comparison method was employed, where students were placed into either a control or a treatment group. Data was collected from assignment and final grades, as well as self-reported time spent using the notebook. Independent t-tests and correlation were used for data analysis. Results were inconclusive but did indicate that the intervention had a possible effect. Further studies may explore better efficacy, implementation, and satisfaction of interactive notebooks across a larger population and multiple class topics.

Syftet med studien är att undersöka och analysera konceptet Fotbollsutvecklare i förening utifrån ledares perspektiv inom ett antal föreningar. Genom att studera ledares perspektiv och erfarenheter av rollen undersöks individens påverkan på organisationens olika delar och dess bidrag till den goda idrottsliga utvecklingsmiljön. Studiens empiriska underlag består av sex kvalitativa intervjuer från tre olika föreningar där resultatet har analyserats utifrån teoretiska perspektiv som anspelar på och förklarar utvecklingsmiljöns påverkbara faktorer samt hur coachen verkar i ett sammanhang och hur det påverkar dennes metoder. Därtill har resonemang förts kring viktiga komponenter hos en god idrottslig miljö och en god ledarutvecklare. Studiens resultat visar att fotbollsutvecklarens arbete har en positiv påverkan på organisationens röda tråd, dess ledare, utövarens familj och spelaren själv. För att fotbollsutvecklaren ska generera positiva resultat krävs det att dennes personlighet präglas av engagemang, driv, vilja och stort kunnande. / The purpose with this study is to examine and analyze the concept Football developers from the perspective of leaders within several associations. By studying the leader’s perspective and experiences of the role, the individual’s influence on the various parts of the organization and its contribution to the good sporting development environment are examined. The study’s empirical basis consists of six qualitative interviews from three different associations, the results of which have been analyzed based on theoretical perspectives that allude to and explain the influenceable factors of the development environment as well as how the coach works in a context and how it affects his methods. In addition, reasoning has been carried out around important components of a good sporting environment and a good leader developer. The result of the study show that the football developer’s work has a positive impact on the organization’s common thread, its leaders, the practitioner’s family, and the player himself. For the football developer to generate positive results, it is necessary that his personality is characterized by commitment, drive, will and drive, and great knowledge.

However, integrated development environments supporting all phases of agent-oriented development are still missing. MADAE-Pro is a process for the development and reuse of family of multi-agent systems and integrates two complementary process. One is based on Domain Engineering concepts, aiming in creating artifacts of reusable software in the development of an application family in a particular domain problem, and the other is based on Application Engineering, which guides the construction of applications based on reusable software artifacts previously produced in the Domain Engineering process. The environment includes the ONTORMAS ontology and, through inference rules and semantic search over its instances, automates the modeling tasks of the MADAE-Pro process. These features allow for the developer productivity gains and for maintaining the consistence of the knowledge-base, ensuring the success of the reuse in future applications. / O paradigma de desenvolvimento orientado a agentes tem atingido um alto nível de maturidade na última década. Entretanto, ainda faltam ambientes integrados de desenvolvimento de software que suportem todas as fases do desenvolvimento orientado a agentes. MADAE-Pro é um processo para o desenvolvimento e reuso de famílias de sistemas multiagente e integra dois subprocessos complementares. Um é baseado nos conceitos da Engenharia de Domínio, isto é, visa construir artefatos reutilizáveis que representem uma família de aplicações e o outro, baseado na Engenharia de Aplicações, guia o desenvolvimento de uma aplicação específica reutilizando os produtos do primeiro subprocesso. Este trabalho propõe MADAEIDE, um ambiente integrado de desenvolvimento baseado no conhecimento que automatiza o processo desenvolvimento de software multiagente MADAE-Pro. O ambiente agrega a ontologia ONTORMAS e, através de regras de inferência e buscas semânticas diretamente sobre suas instâncias, automatiza as tarefas de modelagem do processo MADAE-Pro. Estas características levam a um ganho de produtividade por parte do desenvolvedor, além de manter uma base de conhecimento consistente, garantido o sucesso do reuso em futuras aplicações.

The rapidly evolving technologies in the automotive industry have been defining new challenges, setting new goals and consenting to more complex systems. This steered the AUTOSAR community toward the independent development of the AUTOSAR Adaptive Platform with the intention of addressing and serving the demands defined by the new technology drivers. The use of an already existing software based on an open-source development - specifically GNU/Linux - was recognized as a matching candidate fulfilling the requirements defined by AUTOSAR Adaptive Platform as its operating system. However, this raises new challenges in addressing the safety aspect and the suitability of its implementation in safety-critical environments. As safety standards do not explicitly handle the use of open-source software development, this thesis proposes a tailoring procedure that aims to match the requirements defined by ISO 26262 for a possible qualification of GNU/Linux. And while very little is known about the behavior specification of GNU/Linux to appropriate its use in safety-critical environments, the outlined methodology seeks to verify the specification requirements of GNU/Linux leveraging its claimed compliance to the POSIX standard. In order to further use GNU/Linux with high pedigree of certainty in safety-critical applications, a software partitioning mechanism is implemented to provide control over the resource consumption of the operating system –specifically computation time and memory usage- between different criticality applications in order to achieve Freedom from Interference. The implementation demonstrates the ability to avoid interference concerning required resources of safety-critical applications.
