Dyviks samfällighet ligger i Nynäshamns kommun och består av totalt 86 fastigheter. Samfälligheten sköts av den samfällighetsförening som alla fastighetsägare är medlemmar i. Föreningen arbetar på ideell basis. Föreningens verkställande ledning, styrelsen, arbetar med att admini-strera föreningens medlemmar, fastigheter samt egendomar. Dessa administrativa arbetsuppgifter har utförts på ett manuellt och tidskrävande sätt. Styrelsen har därför efterfrågat ett digitaliserat system som kan utföra många administrativa uppgifter med en mer automatiserad metod och ökad pålitlighet. Projektets syfte har varit att ta fram ett sådant system för att effektivisera styrelsens administrativa arbetsuppgifter. Projektet har inneburit att genom arbetsmodellen CDIO ta fram en passande systemlösning som motsvarar de problemområden och krav som identifierades under projektet. Framtagandet av lösningen har berört alla moment såsom att analysera problemet genom en förstudie, designa och implementera systemet, testa det samt ta fram en plan för hur systemet ska produktionssättas. Varje krav och funktion har implementerats med en inkrementell arbetsprocess. Resultatet blev ett system med den nödvändigaste funktionaliteten implementerad. Systemet låter styrelsemedlemmarna administrera föreningens intressen (sektioner, båtplatser, medlemmar och fastigheter) samt generera rapporter och medlemmarnas fakturor. Projektet har även resulterat i en utvärdering av hur systemet ska behandla personuppgifter i enlighet med de juri-diska aspekter som existerar, exempelvis personuppgiftslagen, samt en grov ekonomisk driftplan. / Dyviks community is located in Nynäshamns municipality and consists of a total of 86 properties. The community is maintained by the community association that all property owners are members. The association works on a volunteer basis. The association’s executive managing instance, the board, works with administrating the association members, properties and estates. These administration tasks have been carried out in a manual and time-consuming manner. The board has therefore requested a digitalized system that can perform many of the administra-tion tasks with a more automated method and increased reliability. The project’s aim has been to develop a system to streamline the board’s administrative duties. The project has meant that with the working model CDIO design a fitting solution that meets the concerns and requirements identified during the project. The development of the solution has touched all aspects such as analyzing the problem through a pilot study, designing and implementing the system, testing it and developing a plan for how the system should be deployed. Each requirement and function has been implemented with an incremental working procedure. The result was a system with the most necessary functionality implemented. The system allows board members to administer the association's interests (sections, berths, members and properties) and generate reports and members' bills. The project has also resulted in an evaluation of how the system will process personal data in accordance with the legal issues that exist, such as the Data Protection Act, and a rough economic operation plan.

Sustainability study in the ever-growing Information technology (IT) sector is an emerging interdisciplinary research field. As one essential element in this sector, the development and implementation of cloud-based autonomous vehicles have the great potential to bring convenience to society and are defined as the climate change mitigation strategy. For instance, autonomous vehicles are able to fully utilize the eco-driving systems to reduce carbon emissions and reach high energy efficiency. Previous studies have shown that cloud IT service, one of the critical technologies for autonomous vehicles, is likely to yield novelties and advantages to the IT industry and reduce the greenhouse gas (GHG) emissions from other sectors. However, cloud services and their data center infrastructures consume plenty of electricity globally and cause GHG emission impacts. Robust methodologies to assess the environmental impacts related to cloud IT solutions are still lacking in academia and industry. In sum, there are knowledge gaps between empirical studies and general interest in software- supported and data-driven autonomous vehicles and their cloud service.  The purpose of this study is to investigate the possibilities and challenges connected to the assessment of the GHG impact related to cloud IT solutions in an autonomous vehicle set up. This study also aims to explore possible recommendations to reduce the GHG emission of cloud IT services. A qualitative in-depth case study is performed. The primary data is collected by semi-structured interview method, while the secondary data is collected by the scoping literature review method. The interviews are conducted with employees with different roles related to cloud services and/or sustainability at the case company.  The findings show the lack of transparent methodologies and calculation guidelines to assess cloud GHG emissions, both in the research community and industry. It shows the great opportunity and market demand for sound assessment methodologies and tools. Besides, six challenges to assessing cloud GHG emissions on the autonomous vehicle set up are identified: i) assessing system boundaries, ii) data quality and collection methods, iii) measurement methodologies, iv) calculation process, v) validation process, and vi) some other challenges. Additionally, five possible recommendations are developed to reduce the cloud GHG emissions: i) cloud GHG emission visualization and measurement tool, ii) better promotional schemes for user’s awareness and engagement, iii) investigations on both top-down and bottom-up approaches, iv) optimization through usage demand shaping, and v) optimization of the infrastructure services.

Cloud computing brought flexibility, scalability, and capital cost savings to the IT industry. As more companies turn to cloud solutions, securing cloud based services becomes increasingly important, because for many organizations, the final barrier to adopting cloud computing is whether it is sufficiently secure. More users rely on cloud storage as it is mainly because cloud storage is available to be used by multiple devices (e.g. smart phones, tablets, notebooks, etc.) at the same time. These services often offer adequate protection to user's private data. However, there were cases where user's private data was accessible to other users, since this data is stored in a multi-tenant environment. These incidents reduce the trust of cloud storage service providers, hence there is a need to securely migrate data from one cloud storage provider to another. This thesis proposes a design of a service for providing Security as a Service for cloud brokers in a federated cloud. This scheme allows customers to securely migrate from one provider to another. To enable the design of this scheme, possible security and privacy risks of a cloud storage service were analysed and identified. Moreover, in order to successfully protect private data, data protection requirements (for data retention, sanitization, and processing) were analysed. The proposed service scheme utilizes various encryption techniques and also includes identity and key management mechanisms, such as "federated identity management". While our proposed design meets most of the defined security and privacy requirements, it is still unknown how to properly handle data sanitization, to meet data protection requirements, and provide users data recovery capabilities (backups, versioning, etc.). / Cloud computing erbjuder flexibilitet, skalbarhet, och kapital kostnadsbesparingar till IT-industrin. Eftersom fler företag vänder sig till moln lösningar, trygga molntjänster blir allt viktigare, eftersom det för många organisationer, det slutliga hindret att anta cloud computing är om det är tillräckligt säkert. Fler användare förlita sig påmoln lagring som det är främst pågrund moln lagring är tillgängligt att användas av flera enheter (t.ex. smarta telefoner, tabletter, bärbara datorer, etc.) påsamtidigt. Dessa tjänster erbjuder ofta tillräckligt skydd för användarens privata data. Men det fanns fall där användarens privata uppgifter var tillgängliga för andra användare, eftersom denna data lagras i en flera hyresgäster miljö. Dessa händelser minskar förtroende molnleverantörer lagring tjänsteleverantörer, därför finns det ett behov av att säkert migrera data från en moln lagring till en annan. Denna avhandling föreslår en utformning av en tjänst för att erbjuda säkerhet som tjänst för molnmäklare i en federativ moln. Detta system gör det möjligt för kunderna att säkert flytta från en leverantör till en annan. För att möjliggöra utformningen av detta system, möjliga säkerhet och risker integritet av ett moln lagring tjänst har analyserats och identifierats. Dessutom att man framgångsrikt skydda privata uppgifter, dataskydd krav (för data retention, sanering och bearbetning) analyserades. Den föreslagna tjänsten systemet utnyttjar olika krypteringsteknik och även inkluderar identitet och nyckelhantering mekanismer, såsom "federerad identitetshantering". Även om vår föreslagna utformningen uppfyller de flesta av den definierade säkerhet och integritet krav, är det fortfarande okänt hur korrekt hantera data sanering, för att uppfyller kraven för dataskydd och ge användarna data recovery kapacitet (säkerhetskopior, versionshantering osv.)

Background Using Microsoft Platforms as a base for creating a software solution with a web front-end, the motives and research behind the technology was explored. This study identified functionalities that are split across existing media-related applications where neither has all to develop and evaluate a novel solution with useful features for sorting and indexing media. Aim Produce a solution for the development of an application with available technology, provide research and motives for chosen implementation strategies, and an evaluation of the solution. Method Design and creation was used as a strategy for the purpose of developing and evaluating a software solution. A literature review was used as data collection method, serving as motive and research behind the development of a software solution. An evaluation on accessibility, functionality and performance was chosen to estimate the worth of the proposed solution, and to be compared with Kodi and Squeezebox. Results The proposed solution suffered in performance and accessibility. In terms of functionality, it has the edge by being cloud-hosted,having offline support and supporting multiple media types. Kodi excelled in supporting more media types and formats, with an accessibility score close to Zavorite. Squeezebox excelled in performance. Both Squeezebox and Kodi has the edge in being able to playback media, a feature Zavorite does not offer. Conclusions Zavorite is a prototype evaluated alongside product-ready applications. The areas where Zavorite is lacking compared to Kodi or Squeezebox, such as performance is made up for due to being a PWA. For accessibility, the evaluation showed what should be improved for subsequent prototypes. For functionality, despite the prototype only showcasing two media types, there is the possibility of adding more with an additional row in a database table. Zavorite can be considered a combination of Kodi and Squeezebox, with user experience improvements as a PWA, limited to sorting and indexing media.

Arkitektoniska beslut har ofta långvariga effekter på system. När beslut leder till ökad komplexitet, underhållbarhet och hämmad utvecklingshastighet, uppstår arkitektonisk teknisk skuld. Arkitektonisk teknisk skuld kan betraktas som mer relevant än någonsin i en tid där vi inte bara är mer beroende av våra informationssystem än någonsin, de är också mer komplexa än någonsin. Systemen fortsätter öka i skala och ny teknologi, såsom AI, tillkommer och blir snabbt en del av gemene mans vardagliga arbete. Arkitektoniska beslut fattas inte bara vid ett tidigt skede med dagens agila utvecklingsmetoder, utan kontinuerligt under iterationer. Detta kan leda till genvägar och därmed suboptimala arkitektoniska beslut, vilket i sin tur kan ge upphov till arkitektonisk teknisk skuld över tid. Denna masteruppsats om arkitektonisk teknisk skuld i en molnbaserad miljö är en fallstudie som undersöker organisationer verksamma inom CRM-systemet Salesforce, mer specifikt systemutveckling inom ramen för detta. Studien undersöker organisationernas uppfattning och hantering av fenomenet, men även hur deras attityder och risktagande ser ut vid arkitektoniska beslut. Studien presenterar tidigare forskning om teknisk skuld, den finansiella metaforen av Ward Cunningham, arkitektonisk teknisk skuld, en kategori av teknisk skuld, och använder två teoretiska ramverk: en deskriptiv modell för att tolka arkitektonisk teknisk skuld och en analytisk modell som kategoriserar teknisk skuld enligt Fowlers kvadranter, med en arkitektonisk tappning. Resultatet består av en empirisk insamling där dokumentation från Salesforce presenteras och åtta respondenter med olika roller har intervjuats. Studien visar att det råder skillnader i hur organisationer hanterar arkitektonisk teknisk skuld beroende på uppdragsgivarens roll och förståelse, att det finns utmaningar med att få hantering av arkitektonisk teknisk skuld prioriterad, samt att det råder både vårdslösa och eftertänksamma attityder. / Architectural decisions often have long lasting effects on information systems, when these decisions lead to increased complexity, maintainability, and inhibited development speed, architectural technical debt arises. Architectural technical debt can be considered more relevant than ever in an age where we are not only more dependent on our information systems than ever, they are also more complex than ever. The systems continue to increase in scale and new technology, such as AI, is added and quickly becomes part of the everyday work of the average person. Architectural decisions are made not only once at an early stage with today’s agile development methods, but continuously during iterations. This can lead to shortcuts and thus suboptimal architectural decisions, which in turn can create architectural technical debt over time. This master’s thesis on architectural technical debt in a cloud-based environment is a case study that examines organizations operating within the CRM system Salesforce, more specifically system development within this framework. The study examines the organizations' perception and management of the phenomenon, but also what their attitudes and risk-taking look like in architectural decisions. The study presents previous research on technical debt, the financial metaphor of Ward Cunningham, and architectural technical debt, a category of technical debt, and uses two theoretical frameworks: a descriptive model to interpret architectural technical debt and an analytical model that categorize technical debt according to Fowler’s quadrants, with an architectural angle. The result consists of an empirical collection where documentation from Salesforce is presented and eight respondents with different roles have been interviewed. The study shows that there are differences in how organizations handle architectural technical debt depending on the client's role and understanding, that there are challenges with getting handling of architectural technical debt prioritized, and that there are both reckless and prudent attitudes.

Under detta examensarbete har en lösning framtagits som underlättar distansmonitorering av patienter. Då olika medicinska produkter skickar data till sina egna plattformar blir det krångligt för både patienten och vårdgivaren att ta fram och hålla koll på alla vitalparametrar som tas. Därför har en gemensam plattform, LinkWatch, utvecklats. Idag kan flera vitalparametrar mätas och ses i plattformen. En säker och effektiv dataöverföring mellan en blodsockermätare och LinkWatchs webbserver har gjorts för att utöka funktionaliteten på LinkWatch. Målet med projektet var att integrera en blodsockermätare med LinkWatch. Arbetet har utförts i programmeringsspråken Kotlin och Swift. För att få kunskap om dataöverföringen söktes information om bland annat standarden FHIR, Bluetooth Low Energy samt tidigare arbeten. Resultatet av arbetet är två applikationer, en för iOS och en för Android. Mobilapplikationerna kan koppla sig till blodsockermätaren via Bluetooth, överföra dess värden till mobilen samt skicka dessa till LinkWatchs webbserver. Applikationerna har enkla användargränssnitt och enkla layouter för att underlätta patientens användning av applikationerna. Använder patienten LinkWatch, kan patienten se sitt blodsockervärde tillsammans med andra vitalparametrar och på så sätt få en bra överblick över sin hälsa. Projektet är positivt för diabetiker och andra som är intresserade av hälsa. Tack vare den användarvänliga plattformen och mångsidigheten av LinkWatch, kan användare enklare kunna hålla koll på sitt blodsockervärde och göra livsviktiga åtgärder vid uppkomst av symtom. Vidare kan även vårdgivare ta del av information som LinkWatch lämnar ut för att exempelvis se trender i patientens blodsockervärden. Fördelarna med att dela data med vårdgivaren är bland annat reducerade kostnader och ökad trygghet hos patienterna. / During this project, a solution has been developed that promotes remote patient monitoring. As different medical products send data to their own platforms, it becomes troublesome for both the patient and the care provider to take and keep track of all the vital parameters. Hence a common platform, LinkWatch, has been developed. LinkWatch is a platform where all the patient's medical signs can be seen. To increase the functionality of LinkWatch, a secure and efficient data transfer between a blood glucose meter and LinkWatch’s web server has been established. The goal of this project was to integrate a blood glucose meter with LinkWatch. The programming languages Kotlin and Swift were used to develop the mobile applications. To gain knowledge about the data transfer, research was done to obtain information about the FHIR standard, Bluetooth Low Energy and previous work in the field. The results of the project are two applications, one for iOS and one for Android. The mobile applications can connect to the blood glucose meter with Bluetooth, transfer its values to the mobile phone and send these to LinkWatch’s web server. When the records are in LinkWatch’s system, the patient is able to see their glucose levels along with other vital parameters. This project will have a major impact on patients with diabetes and others who are interested in health. Thanks to the user-friendly platform and the flexibility of LinkWatch, users of the application will be able to more easily keep track of their blood sugar value and take early action in the event of symptoms. Furthermore, health care providers can also take part in information that LinkWatch will provide, for example see trends in the patient's blood sugar values. The benefits with sharing data with the health care providers are cost reductions and increased patient satisfaction.
