1. Projective Geometry in Kinematics
Master-uppsats, Umeå universitet/Institutionen för matematik och matematisk statistikSammanfattning : In this thesis, we study projective geometry and show a connection to kinematics. We show how the group of rigid body motions in three-dimensional space can be parameterized on a hyperbolic quadric in a seven-dimensional projective space. We also show that this quadric is a geometry with triality, and we discuss triality from a kinematic viewpoint. LÄS MER
2. Branching Out with Mixtures: Phylogenetic Inference That’s Not Afraid of a Little Uncertainty
Master-uppsats, KTH/Matematisk statistikSammanfattning : Phylogeny, the study of evolutionary relationships among species and other taxa, plays a crucial role in understanding the history of life. Bayesian analysis using Markov chain Monte Carlo (MCMC) is a widely used approach for inferring phylogenetic trees, but it suffers from slow convergence in higher dimensions and is slow to converge.

3. Homomorphic encryption
Master-uppsats, KTH/Matematik (Avd.)Sammanfattning : The problem of constructing a secure encryption scheme that allows for computation on encrypted data was an open problem for more than 30 years. In 2009, Craig Gentry solved the problem, constructing the first fully homomorphic encryption (FHE) scheme. LÄS MER
4. Är blockmodellen en modell att räkna med? : En intervjustudie om grundlärares erfarenheter av blockmodellen i matematikundervisningen
Uppsats för yrkesexamina på avancerad nivå, Jönköping University/Högskolan för lärande och kommunikationSammanfattning : En utgångspunkt för denna studie har varit att flera svenska elever har svårigheter att lösa matematiska textuppgifter. I ett försök att utveckla elevers förmågor att lösa matematiska textuppgifter har Singaporemetoden blivit allt mer populär. I Singaporemetoden används blockmodellen för att visualisera textuppgifter.

5. Predicting the Impact of Supply Chain Disruptions Using Statistical Analysis and Machine Learning
Master-uppsats, KTH/Matematisk statistikSammanfattning : The dairy business is vulnerable to supply chain disruptions since large safety stocks to cover up losses are not always a viable option, therefore it is crucial to maintain a smooth supply chain to ensure stable delivery accuracies. Disruptions are unpredictable and hard to avoid in the supply chain, especially in cases where production errors cause lost production volume. LÄS MER
