I dagens samhälle blir det allt viktigare med säker kommunikation. Varje dag förlitar länder, företag och vanliga människor sig på säker kommunikation. Det kan vara personer som handlar på nätet, företag som förmedlar affärshemligheter eller länder som vill se till att valresultat inte läcker ut i förtid. Det är därför lätt att förstå behovet av kommunikation som är säker mot tjuvlyssnare. Det är The main aim of this thesis is to study the suitability of Semi Definite Programs (SDPs) as a method to solve problems in multipartite Quantum Key Distribution (QKD). Using SDPs to solve quantum information problems numerically is interesting because the solutions give strict upper (or lower) bounds which can be used to prove the security of protocols. In this thesis the security of QKD protocols

Unseen Sights: Magic, Modernity, and Childhood in Children’s Urban Fantasy explores and analyses the genre of children’s urban fantasy. Drawing upon a combination of fantasy, urban fantasy, and children’s literature scholarship, the thesis considers how children’s urban fantasy works – investigating both its forms and functions, and how it performs work in the world.The genre is analysed both sync

Background: Wrist osteoarthritis can cause persistent pain, reduced joint mobility, and difficulty performing daily activities, negatively impacting quality of life. Although patient education and exercise therapy are recommended as first-line treatments for osteoarthritis in other joints, evidence supporting these strategies for wrist osteoarthritis remains limited. This randomized controlled tri

Viruses are ubiquitous in all environments and impact host metabolism, evolution, and ecology, although our knowledge of their biodiversity is still extremely limited. Viral diversity from genomic and metagenomic datasets has led to an explosion of uncultivated virus genomes (UViGs) and the development of specialized databases to catalog this viral diversity, though many lack comprehensive integra

This thesis investigates how Artificial Intelligence can collaborate across the entire product development process, using the case of playfulness through lighting as the design context. The project follows the development of a playful table lamp from early research to the final product, comparing traditional methods with AI-assisted approaches to understand where AI adds value and where human expe

Environmental simulations are increasingly used in urban planning to assess parameters that influence adequate living conditions in densification projects, such as daylight access, noise exposure, wind comfort, and flood risk. These simulations rely on geospatial data and on the representation of the urban environment through 3D city models. However, in current planning practice, simulation result

In this essay we examine intelligence cooperation between Finland and Sweden during the time period 1943-1948 to test a proposed theory of intelligence sharing by Brown & Farrington. This theory posits that intelligence sharing will occur if three prerequisites are present, labelled Reason, Route and Record. We use archival material in addition to previous historical research to investigate in

On September 2, 2025, the United States launched a series of military strikes on boats that allegedly departed from Venezuela. Using narrative analysis, this study examines the strategic narratives that the Trump administration communicates about Venezuela, in relation to the American strikes, through its official communications on X and Truth Social. The study also examines the strategies used to

This paper applies Sykes and Matza’s theory of neutralization (1957) to three cases of convicted, self-interested spies: Peyman Kia, Stig Wennerström, and Robert Hanssen. Using congruence analysis, the study assesses the explanatory strength of the theory, with qualitative text analysis as the primary method to identify neutralizations in Kia’s interrogation transcripts, Wennerström’s autobiograph

This thesis examines how Swedish intelligence actors use intelligence disclosures as strategic communication to address hybrid threats. The study applies a qualitative document analysis to the Swedish Security Service’s and Swedish Military Security and Intelligence Service’s open annual reports and yearly assessments from 2015 and 2024. The material is analysed using Nato’s framework for intellig
