  1. 1. Projective Geometry in Kinematics

    University essay from Umeå universitet/Institutionen för matematik och matematisk statistik

    Author : Emil Eriksson; [2024]
    Keywords : ;

    Abstract : 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. READ MORE

  3. 2. Island of the Roses : A case study of the ontological threat of a micronation

    University essay from Försvarshögskolan

    Author : Lukas Gunnarson Hellerstedt; [2024]
    Keywords : ;

    Abstract : 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.

  4. 3. Multiscale & Multiphysics Modelling of Thrust Pad (Air) Bearings

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Nipon Roy; [2023]
    Keywords : Finite element modelling; Air bearing; Multiphysics simulations; Air lubrication; surface texture; Topology optimization;

    Abstract : 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. READ MORE

  5. 4. Wrist Angle Estimation Using Two Wearable Inertial Measurement Units

    University essay from KTH/Medicinteknik och hälsosystem

    Author : Arvin Razavi; [2023]
    Keywords : IMU wrist angle estimation; Wrist absolute angle; IMU-based human motion capture; orientation filter; Complementary filter; Kalman filter; IMU handledsvinkeluppskattning; handleds absolutvinkel; IMU-baserad mänsklig rörelsefångst; orienteringsfilter; komplementfilter; Kalman-filter;

    Abstract : 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. READ MORE

  6. 5. Polarizability and Orientation Dynamics of Small Proteins

    University essay from Uppsala universitet/Materialteori

    Author : Ebba Koerfer; [2022]
    Keywords : Protein orientation; single-particle imaging; polarizability; orientation dynamics; rigid rotor model;

    Abstract : Proteins often carry an intrinsic electric dipole moment, which can interact with external electric fields and cause protein motion. Previous research has found that the orientation of small proteins in gas phase can be controlled in a static electric field. READ MORE
