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. Predicting True Sepsis and Culture-positive Sepsis in Intensive Care Unit with Machine Learning Techniques
Master-uppsats, Lunds universitet/Matematisk statistikSammanfattning : Sepsis, a serious medical condition often leading to patients requiring intensive care, has prompted numerous scientists to employ mathematical techniques to aid in its diagnosis. This thesis uses logistic regression and a machine learning technique, XGBoost, to predict true sepsis (as opposed to sepsis mimics) and culture-positive sepsis (among true sepsis) in critical care using blood test results, physiological measurements and other patient characteristics.

3. The Abel-Ruffini Theorem : The insolvability of the general quintic equation by radicals
Kandidat-uppsats, Umeå universitet/Institutionen för matematik och matematisk statistikSammanfattning : This thesis explores the topic of Galois theory at a relatively introductory level with the goal of proving the Abel Ruffini theorem. In the first part algebraic structures are considered: groups, ring, fields, etc. Following this, polynomial rings are introduced and the attention is then turned to finite field-extensions. LÄS MER
4. Where to Fuse
Master-uppsats, Lunds universitet/Matematisk statistikSammanfattning : This thesis investigates fusion techniques in multimodal transformer models, focusing on enhancing the capabilities of large language models in understanding not just text, but also other modalities like images, audio, and sensor data. The study compares late fusion (concatenating modality tokens after separate encoding) and early fusion (concatenating before encoding) techniques, examining their respective advantages and disadvantages.

5. Auktoriteter i matematikundervisningen - en inferentialistisk analys av kooperativt lärande
Kandidat-uppsats, Göteborgs universitet/Institutionen för pedagogik och didaktikSammanfattning : Syftet med denna studie har varit att ge en fördjupad förståelse för kooperativt lärande i matematikundervisning genom att visa på de sociala aspekter som avgör vilka beslut elever tar i ett grupparbete. Frågeställningen för studien är: Vilka auktoriteter kan identifieras i ett kooperativt arbetssätt inom mätning och statistik. LÄS MER
