This thesis introduces TrustNet, a flexible and distributed system for deriving, and interacting with, computational trust. The focus of the thesis is applying TrustNet as a tool within distributed chat systems for implementing a subjective moderation system. Two distributed chat systems, Secure Scuttlebutt and Cabal, are discussed, the latter having been extended with a proof of concept implement

Det pågår en ökning av skönhetsingrepp i vårt samhälle och tidigare studier tenderar att visa på samband mellan skönhetsingrepp och personlighetsdrag. Den här studiens syfte var att granska sambanden mellan självkänsla, social anpassning och skönhetsingrepp genom en kvantitativ undersökning. Studien undersökte om lägre grad av självkänsla och högre grad av social anpassning påverkar attityden tillThere is an increase in cosmetic surgery in our society and more recent studies tend to show links between beauty procedures and personality traits. The aim of this study was to review the relationships between self-esteem, social adaptation and cosmetic surgery through a quantitative survey. The study examined whether lower levels of self-esteem and higher levels of social adaption affect attitud

Denna masteruppsats studerar den nuvarande upphovsrätten inom EU och fastställer om det för närvarande finns skydd för AI-producerade verk. Det finns möjlighet att skydda verk som har blivit skapade av AI-system om det finns en länk mellan den mänskliga upphovsmannen och det slutliga verket. I detta fall betraktas AI-systemet som ett redskap för att skapa ett specifikt alster. Om länken mellan denThis master thesis discusses current copyright rules and if there is presently a copyright protection for these types of works. There is a possibility to protect works that have been generated by AI’s. However, this is only possible if a human is using the AI as a ”tool”, in order to reach a certain end-goal. There has to be a clear link between the human author and the machine, otherwise neither

The effects of a change of environment on water kefir’s microbial diversity was studied by splitting up two existing cultures (stem 1 and stem 2) among several households and culturing them for three weeks using the same method and ingredients. Next Generation Sequencing (NGS) was used on the 16S rRNA gene to identify bacterial families, genera and strains. Sphingomonadaceae, Lactobacillaceae, Ace

Collective memory is a psychological and sociological concept. This theory provides a reference for defining the characteristics of a community from the perspective of memory. Further research also shows that its internal connection to culture and community. This has many similarities with user research in product design. By focusing on typical or iconic products, objects, or the interacting proce

In this thesis a framework for finding anomalies in streaming data is proposed. The framework proposed is not necessarily applicable only to problems in anomaly detection, but could be applied to other problems as well. There are three main concepts at play in the framework: (i) Active Learning, a learning algorithm which can query a human specialist for labels of instance such that the model can

The concept of an open air drug market can be defined as a widely known area wherein public trade and use of narcotics is prevalent. This phenomenon contradicts the legislation in place regarding drug use and distribution in Sweden. This case study analyses an open air drug market located in the outskirts of Stockholm. The study specifically reviews the crime prevention methods used by law enforce

For a long time, a method which tunes a robust controller automatically has been researched. In this thesis, a method to estimate processes using a short experiment and low order time delayed models is described. The goal was to achieve a model that could be used for PI- and PID-tuning in an autotuner. Through a simulation study, various experiment designs were tested to find an optimal experiment

The aim of this study is to challenge the Swedish gender equality discourse which has a central focus on gender relations and therefore ignores other power structures. The purpose is also to examine how the public space excludes certain bodies and how the urban planning creates an expectation of heterosexuality, whiteness and doing gender based on cisnormativity. The material used for the analysis

Problem/Bakgrund: entreprenörskap som företeelse har sedan GY 11 infördes gjort entré i gymnasieskolan och blivit en del av gymnasieskolans uppdrag, men begreppet är mångfasetterat och ibland även laddat med känslor och åsikter. Denna mångtydighet ger upphov till olika möjliga tolkningar och därmed konsekvenser för verksamheten och i förlängningen för eleverna. Syfte: syftet med denna uppsats är

I detta kandidatarbete undersöks förutsättningarna för och effekterna av en övergång från produktionsbaserade utsläppsberäkningar till konsumtionsbaserade utsläppsberäkningar inom internationell respektive svensk klimatpolitik. Studien utförs i form av en litteraturstudie. Resultatet visar att det är mycket svårt att avgöra vad effekterna av en övergång till konsumtionsbaserade utsläppsberäkningaThis literature study examines the potential for and effects of a transition from production-based to consumption-based accounting in international and Swedish climate policy, respectively. The result shows that it is very difficult to determine what the effects of such a transition would be, both on the international and Swedish level. Regarding the question of responsibility for emissions, none

The Swedish power grid is actively balanced in order to maintain the nominal frequency of 50 Hz. Today, this is mostly done through flexible power generation. Emerging markets, allowing consuming resources to participate in balancing the grid, have the potential to increase the stability of the grid. This master thesis aimed to investigate the consequences and possibilities of using variable air v

Hydroponics is a method for cultivating plants with their roots suspended in water. This means that the nutrients normally present in the soil have to be supplied artificially, in an appropriate amount. Electrical conductivity can be used to measure the nutrient concentration in a hydroponic solution. This thesis implements a small-scale model of an automated hydroponic farm. The nutrient concentr

Hydropower is simply the largest source of renewable energy in the Nordic countries, where It compose around 90% of power production in Iceland, 70% in Norway, 40% in Sweden and 20% in Finland. Mountainous terrain and abundance in the surface water is a significant contributing factor in hydropower production. Hydropower is also considered more reliable and continuous than other forms of renewable

Inkommande avloppsvatten till ett reningsverk består till största delen av organiskt material som i sin tur kan utgöra en viktig resurskälla för reningsverket. Genom att utnyttja kolet i avloppsvattnet för produktion av metan kan ett reningsverk bli självförsörjande på energi. En nackdel kan dock vara att det lättnedbrytbara organiska materialet, som viktiga reningsprocesser såsom denitrifikation

In doing so, the thesis is conducted to provide definition and tools of the human right diplomacy that have been utilized by State and Non-State actors at all level. The thesis also examines the human rights situations in Cambodia with the focus on labour r

I vårt stora, komplexa universum är det uppskattat att det finns ungefär två biljoner galaxer. Just vår hemgalax, Vintergatan, ligger mellan de två typiska galaxpopulationerna, i den så kallade "gröna dalen". Galaxer i den gröna dalen är i en fas mellan att aktivt bilda stjärnor och att vara döda. I och med detta så kan vi lära oss mycket om galaxers utveckling genom att studera VintergaOne of the biggest mysteries astronomers wish to unveil is the formation and evolution of galaxies. Properties of our own galaxy, the Milky Way, can provide great insight into these. The star formation rate (SFR) and whether it varies with distance from the galactic centre (GC), is one of these properties. Studies indicate that the SFR is higher in the bulge region than in the local thick disk of

Resultatet av #metoo-uppropen visar att sexuella trakasserier och sexuellt våld är ett omfattande samhällsproblem, som drabbar kvinnor i högre utsträckning än män. Den här studien går baserat på det ut på att kartlägga attitydskillnader mellan män och kvinnor, relaterat till sexuellt våld och sexuella trakasserier. Studien redogör för troliga bakomliggande orsaker till könsrelaterat våld och under

Problem/Bakgrund ME/CFS har fått medial uppmärksamhet på senare år. Bland annat har olika dödsfall och självmord som relateras till ME/CFS uppmärksammats. Även ME/CFS drabbades sociala och ekonomiska situation har uppmärksammats, och av vissa beskrivits som en orsak till dödsfallen och självmorden. Mot bakgrund av att ME/CFS är ett aktuellt samhällsfenomen med stora konsekvenser för de drabbade, m

Mycoplasma bovis (M. bovis) infections are difficult to diagnose and treat, causing severe economic losses to farms with infected cows. Eurofins Milk Testing Sweden AB screens cow’s milk using qPCR (quantitative Polymerase Chain Reaction) to detect M. bovis infections. Five performance characteristics were chosen to evaluate if ELISA (Enzyme-Linked Immunosorbent Assay) could replace the current sc
