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. Island of the Roses : A case study of the ontological threat of a micronation
Kandidat-uppsats, FörsvarshögskolanSammanfattning : The discipline of OSS’s (Ontological Security Studies) incorporation in Security Studies has helped unravel state behaviour which other IR-theories (International Relations) have struggled to make sense of. Going beyond the physical security concerns which characterise the traditional literature, OSS has up until recently consistently emphasised the psychological threat of harm to the “self” – emanating from a point of departure which renders it disembodied.

3. Multiscale & Multiphysics Modelling of Thrust Pad (Air) Bearings
Master-uppsats, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematikSammanfattning : Without lubrication, machines are not imaginable to perform over a long period of time and complete their designated operations. With its omnipresent availability, the air is capable of functioning as a lubricant in long operations very efficiently. Moreover, thrust bearings support axial loads and transmit power at the same time under heavy loads. LÄS MER
4. Wrist Angle Estimation Using Two Wearable Inertial Measurement Units
Master-uppsats, KTH/Medicinteknik och hälsosystemSammanfattning : Hand-intensive work is closely related to the prevalence of upper body and hand/wrist work-related musculoskeletal disorders (WMSDs) in office work, manufacturing, service industries, as well as the healthcare industry. Some risk factors include vibrations, forceful exertions, heavy manual handling, repetitive motions, and prolonged nonneutral wrist postures. LÄS MER
5. Stjälpning av en byggnad i KL-trä : En utvärdering av stelkroppsmetoden
Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurserSammanfattning : 21% av de växthusgaser som släpps ut i Sverige kommer från byggsektorn. Motsvarande siffra för avfall är 40% (Boverket, 2023). Ett fokus måste därför ligga på att använda hållbara alternativ. KL-trä är förnyelsebart samt minskar genom sin höga prefabriceringsgrad avfall på arbetsplatsen (Ramboll, u. LÄS MER
