Dans cette th??se nous nous consacrons ?? l'??tude des alg??bres qui sont d??riv??es ??quivalentes aux alg??bres inclin??es m-amass??es de type A et [A tilde]. Dans la premi??re partie nous donnons une condition n??cessaire et suffisante pour qu'une alg??bre A soit d??riv??e ??quivalente ?? une alg??bre inclin??e m-amass??e de type A. Dans la deuxi??me partie, nous trouvons une caract??risation du carquois li?? des alg??bres inclin??es m-amass??es de type [A tilde] et finalement nous donnons le crit??re analogue ?? l'ant??rieur pour qu'une alg??bre B soit d??riv??e ??quivalente ?? une alg??bre inclin??e m-amass??e de type [A tilde].

Hur kommunicerar restauranger hållbarhet på sina webbsidor och hur kan den förstås? Syftet med studien är att undersöka hur restaurangerna Agrikultur, Amass, Credo, Oaxen och Relæ kommunicerar hållbarhet på sina webbsidor.Utifrån teorier kring Corporate Social Responsibility (CSR), branding och hållbarhet har vi utfört en semiotisk analys och undersökt fem nordiska restauranger som alla blivit tilldelade ”Sustainability Award 2019” av Guide Michelin.Genom att teoretiskt analysera restaurangernas material med hjälp av vårt analysschema, konstruerat av branding-teorier och semiotik visar studierna på att alla restaurangerna kommunicerar hållbarhet på flera olika sätt. Vissa restauranger kommunicerar sitt hållbarhets- och CSR-arbete redan i deras namn och logotyp medan andra restauranger behöver mer beskrivande bilder och texter i kombination för att ge en bild av deras hållbarhetsarbete. Slutsatsen är att det är viktigt att restaurangerna kommunicerar sitt hållbarhetsarbete eftersom detta är något som visar på deras höga positioner i restaurangbranschen. Vidare visar slutsatsen på problematiken att dela ut ett hållbarhetspris utan att specificera kraven. / How do restaurants communicate sustainability on their websites and how can it be understood? The purpose of the study is to investigate how the restaurants Agrikultur, Amass, Credo, Oaxen, and Relæ communicate sustainability on their websites.Based on theories of Corporate Social Responsibility (CSR), branding, and sustainability, we conducted a semiotic analysis and examined five Nordic restaurants, all of which were awarded the Sustainability Award 2019 by Guide Michelin.By theoretically analyzing the materials of the restaurants by using our analysis scheme, constructed of branding theories and semiotics, the studies show that all the restaurants communicate sustainability in several different ways. Some restaurants already communicate their sustainability and CSR work in their name and logo. While other restaurants need more descriptive images and texts in combination to show their sustainability work. The conclusion indicates that it is important to communicate sustainability in the restaurant industry. Furthermore, the conclusion exposes the problem of awarding a prize for sustainability without specifying the requirements.

The certification of systems in the medical domain aims to ensure that a system is acceptably safein order to bear the CE mark. Such process is exhaustive, expensive, time-consuming and safety-critical.Medical devices shall be re-certified under Medical Device Regulations. The first de-facto platform for re-certification is delivered by AMASS project. This thesis is expected to fill the specific gap: evaluate the compliance re-certification efficiency of the platform in the medical domain during the re-certification effort required as a consequence of a change in the normative space. Due to the lack of demonstrations in this safety-critical domain, the standard for medical devices, ISO 14971 with its versions and the Notified Bodies Recommendation Group (NBRG) Consensus paper are considered. There are several differences among them, in terms of the normative part and the fact whether they are international or only applicable in Europe. The evaluation will be conducted on acase study and the research has followed best practicing in case study design/execution. The focus is on two changes. The first change in the normative space is represented by the introduction of the EU directives (EU Medical Device Directives (MDDs): 90/385/EEC, 93/42/EEC, and 98/79/EC.) in relation to ISO 14971:2007, which required the introduction of ISO 14971:2012 (which applies only to manufacturers placing devices on the market in Europe). The second change is represented by the introduction of ISO 14971:2019, an international standard. Through the tool-chain (EPF Composer-BVR Tool), the families of standards and processes are modeled. The reuse of components is assessed through the application of selected metrics creating the measurement framework.The aim is to increase evidence according to the usefulness of the tool-chain in other domains. This master thesis will contribute with a case study evaluation of the tool-chain (a subset of the platform), considering cross-jurisdictional challenges. This work could represent the starting point for an evaluation where not only reference-processes are considered, but also the processes actually modelled in industrial settings.
