Practical evaluation of chain-like MPC protocols

Bottleneck Complexity (BNC) is a fairly new metric for Secure Multi Party Computation (SMPC) protocols. Two protocols with the BNC in mind are examined in this thesis. One protocol is successfully implemented in the Python programming language, and the BNC, latency and computational complexity of the protocol is examined with positive results. The BNC is independent on the number of parties in the

Classifying Motion Patterns of Bikes using Machine Learning

Electric bikes have become ubiquitous in traffic, and with a growing user base and expensive prices, a demand for bike protection is increasing. Bike protection applications could include detecting and notifying the owner if their bike has been stolen or fallen over. This thesis aims to develop solutions for recognizing and classifying motion patterns of an electric bike to allow for improvements

Du kan inte lura ett barn, eller? - En undersökning om barns skydd vid personifierad onlinereklam

Med digitaliseringens utveckling har personifierad onlinereklam vuxit i hela världen. Det betyder att företag, genom s. k cookies, samlar in personuppgifter om konsumenten för att i sin tur skapa onlinereklam baserad på konsumentens intressen. Cookies är en liten datafil som sparar ner information om konsumenten och sedan med hjälp av bland annat Online behaviour advertising (OBA) kan datafilen meWith the development of digitalization, personalized online advertising has grown worldwide. This means that companies, through so-called Cookies, collect personal data about the consumer to then create online advertising based on the consumer's interests. Cookies are a small data file that saves information about the consumer and then with the help of Online Behavioural Advertising, the data

Attityder till anhörigstöd. En kvantitativ studie om vad anhöriga till närstående med beroendeproblematik anser utgör ett bra anhörigstöd

The purpose of the study has been to look into what relatives of people with addiction problems specify as good relative support. Furthermore, we have investigated whether there are differences between groups such as; women and men as well as external and internal coping strategies linked to stress management in what the respondents perceive as good relative support. We have also investigated whet

Humanium metal

The flow of illegal weapons in developing countries does not only cause injuries and death. A violent society is less equal, less democratic and less likely to develop economically. Humanium metal is a material made of melted, illegal firearms that can be used in commercial production. The Initiative is started by IM development partner, a Swedish NGO, and the surplus finances development projects

En Ex-Jobbares Rosa Guide till Tryggare (och Bättre) Bostäder

Enligt WHO är mäns våld mot kvinnor i nära relationer ett av de allvarligaste hoten mot kvinnors hälsa. Medan det finns många aspekter att ha i åtanke i analysen av detta, kvarstår faktumet att det är i hemmet som våldet sker. Varför är det så? Många arkitekter och teoretiker har länge konstaterat hur våra städer är byggda olika väl för olika typer av kroppar, där möjligtvis vissa kroppar stöttas According to the WHO, domestic violence is one of the most dangerous threats to women’s health. Whilst there are more things to consider, truth is that the home is where all of this violent behaviour takes the stage. Why is that? Many architects and theorists have long made out that our cities are differently well-built for different kinds of bodies, where some are possibly better supported than o

Recommendations for Improving the Use of Risk Matrices in Coarse Risk Analyses

Risk matrices are tables with rows representing consequences, and columns representing frequencies. The risk matrix is considered a simple and convenient tool for visualizing risk. However, it has faced critique from the scientific community. Though risk matrices are extensively applied in practice for visualizing results from coarse risk analyses, there is limited research regarding guidance on i

Upper Ordovician stratigraphy of the Stora Sutarve core (Gotland, Sweden) and an assessment of the Hirnantian Isotope Carbon Excursion (HICE) in high-resolution

En avsevärd anomali i jordens globala kolcykel, känd som Hirnantian Isotope Carbon Excursion (HICE), finns dokumenterad i lagerföljder från Hirnantetagen, i slutet av Ordovicium för cirka 445 miljoner år sedan. Anomalin är kopplad till den samtida globala nedkylningen, bildande av inlandisar och ett massutdöende – Late Ordovician Mass Extinction (LOME). Denna studie undersöker lagerföljder från övThe Hirnantian Isotope Carbon Excursion (HICE) is a major anomaly in Earths global carbon cycle at the end of the Ordovician time period, at ca 445 Ma. The anomaly is intimately associated with substantial cooling of the global climate, expansion of continental ice-sheets and the Late Ordovician Mass Extinction (LOME). The present study investigates the Upper Ordovician to the lowermost Silurian s

Unga kvinnors motivation till ledarskap inom studentlivet

Vad har motiverat kvinnliga medlemmar inom Studentlund att ta sig an en ledarposition inom en studentorganisation och vad upplever deltagarna motiverar dem att leda? Fram till nyligen har forskning om ledarskap mestadels kopplats till maskulina egenskaper snarare än feminina egenskaper. Med detta i åtanke ville vi utforska vad som motiverar kvinnor att söka sig till ledarpositioner. Vi valde att uYoung female leaders are the future, but what motivates them to take on a leadership role? And what motivates them to lead? Until recently leadership research has been mostly connected to masculine traits rather than feminine traits. With this in mind we wanted to explore what motivates females to pursue a leadership role. We chose to specifically look at female leaders within student organization

This study is written in order to answer how young unemployed people experience their time as unemployed and whether it affects them mentally. This study is also written in order to gain an understanding of how these young individuals share their life as unemployed in relation to

Investigating Validity of Semantic Measures vs Rating Scales in Assessing Personality

Within personality research, self-report questionnaires are a common approach. This study takes aim at investigating whether self-report questionnaires are enough, or if semantic measures, through Natural Language Processing, could be a substitute or complementary method, in assessing personality. Based on the Five Factor Model of personality, this study has been divided into two phases. Participa

Fuzzing of PKCS#11 Trusted Application

The main goal of this thesis is to find an effective way to fuzz trusted applications (TAs) with source code residing in trusted execution environment (TEE). While fuzzing TAs has been previously done, no work has been found to utilize the source code of TAs to improve the fuzzing. Utilizing the source code in fuzzing can lead to an increase in code coverage compared to black-box fuzzing, and ther

Den könsrelaterade diskrepansen i operasångares försörjningsmöjligheter

Det första av mina två syften var att undersöka huruvida det finns en könsrelaterad diskrepans gällande operasångares försörjningsmöjligheter. Jag samlade in empiri om antalet arbetstillfällen per röstfack och könsfördelningen vid operautbildningar, samt genomförde en enkätundersökning om hur tidigare studenter vid Sveriges operahögskolor försörjer sig. Slutsatsen kunde dras att det finns en stor The first of my two purposes was to investigate whether there is a gender disparity in the possibilities to make a living as an opera singer. I collected empirical data on the number of jobs per fach and the gender breakdown of students at opera schools, and conducted a survey on how former students at Sweden's opera schools supported themselves. I concluded that there is a large disparity to

Dendritic cell stress responses after exposure to a novel rubber skin sensitizer

Vi utsätts dagligen för en mängd främmande kemikalier, varav vissa är skadliga både för miljön och folkhälsan. Ett exempel är ämnen som orsakar allergiska hudsjukdomar och som är en av de vanligaste orsakerna till arbetsrelaterade sjukdomar inom vissa yrken. Det är därför viktigt att utveckla effektiva metoder för att identifiera och begränsa förekomsten av dessa skadliga ämnen i ett tidigt skede.It is widely recognized that exposure to harmful chemicals can affect our health. Allergic contact dermatitis is an allergic skin disease and one of the most common work-related diseases in today’s society. It can be caused by numerous substances, including rubber chemicals. They can be particularly problematic since many professions have daily contact with rubber chemicals, e.g., by wearing dispo

Stabilisation of modern alcohol-containing emulsions with proteins

The purpose of this project was to study the impact of three different protein systems on the physicochemical stability of alcohol-containing emulsions. Egg yolk plasma, sodium caseinate and whey protein isolate (WPI) were used for that purpose. For this reason, the solubility of the three protein systems in the presence of different levels of ethanol was first determined. Oil–in–water emulsions (
