  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. Data Analysis for Energy Evaluation of Stockholm Campuses

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Esteban Moncayo Villa; [2023]
    Keywords : Data analysis; energy performance; Stockholm Campuses; district heating; district cooling; electricity.; Dataanalys; energiprestanda; Stockholms Campus; fjärrvärme; fjärrkyla; el.;

    Abstract : The building sector is a significant contributor to global greenhouse gas emissions, necessitating the development of energy-efficient measures to address environmental concerns. The availability of building energy data sets enables the application of data analysis techniques to assess building energy conditions, providing greater potential for evaluating building energy demands.

  4. 3. Moving Beyond Two Dimensions : An Evaluation of Four Different Three-Dimensional Locomotion Interfaces for Virtual Reality

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Erik Meurk; [2023]
    Keywords : virtual reality; locomotion; three dimensional; virtuell verklighet; rörelse; tre dimensioner;

    Abstract : This paper presents a comparative evaluation of four 3D locomotion interfaces in virtual reality: Slider, Teleport, Point & Tug, and Arm-Cycle. The study employed a mixed methods approach to assess their performance using a token-collecting task in a virtual environment with obstacles, focusing on efficiency, spatial awareness, usability, task load, presence, and cybersickness.

  5. 4. Polymer gel dosimetry with MRI-readout for 3D dose verification - detector characteristics and clinical applications

    University essay from Lunds universitet/Sjukhusfysikerutbildningen

    Author : Thi Guldhill; [2023]
    Keywords : Medicine and Health Sciences;

    Abstract : Background & Purpose: Radiation therapy is an essential treatment for cancer patients with the ultimate goal to deliver radiation doses to the tumour with precision while minimizing exposure to surrounding healthy tissues. Treatment verification is crucial to ensure the accuracy of radiation delivery, for instance by measuring the radiation dose distribution. READ MORE

  6. 5. Correlation between Surface and Tumour Motion in Lung Cancer - including Deep Learning Perspectives

    University essay from Lunds universitet/Sjukhusfysikerutbildningen

    Author : Caisa Kjellström; [2023]
    Keywords : Medicine and Health Sciences;

    Abstract : Purpose: The purpose of this master thesis was to retrospectively investigate correlation between surface and tumour motion in lung cancer patients, alongside deep learning applications of the results. Additional correlations such as age, tumour volume and anatomical placement of the tumour were also investigated. READ MORE
