  1. 16. Detective Quantum Efficiency in the Image Domain

    University essay from KTH/Fysik

    Author : Per Lundhammar; [2022]
    Keywords : detective quantum efficiency; linear systems theory; projection domain; image domain; x-ray imaging; detektiv kvanteffektivitet; linjär-systemteori; projektionsdomän; bilddomän; röntgenavbildning;

    Abstract : We investigate the signal and noise transform characteristics from the projection domain to the image domain in a linear systems theory framework and predictions of the DQE within this framework are made. A simulation study of a photon counting silicon detector is made from which the energy information is used in order to produce synthetic monoenergetic images. READ MORE

  3. 17. Dynamic Real-Time Fire Propagation for Networked Multiplayer Games

    University essay from Linköpings universitet/Medie- och Informationsteknik; Linköpings universitet/Tekniska fakulteten

    Author : Iris Kotsinas; Viktor Tholén; [2022]
    Keywords : fire simulation; fire propagation; fire; game system; real-time; dynamic system; multiplayer games;

    Abstract : Simulating fire propagation in games can be problematic since it requires immense computational power if the fire is portrayed physically accurate. To decrease the computational power required, simplifications and approximations must be made. READ MORE

  4. 18. Development of a portable immersive experience for use in dementia care

    University essay from KTH/Maskinkonstruktion (Inst.)

    Author : Albin Hjertström; Johannes Prescott; [2022]
    Keywords : ;

    Abstract : A prototype of a product that provides an immersive visual experience for dementia care, developed by Biosfär AB, has shown promising results when used in daily activities and therapy sessions. The project behind this thesis was to develop a concept for a portable version based on the functions of the current prototype. READ MORE

  5. 19. Preparations for photon external beam radiotherapy treatment planning of small animals

    University essay from Lunds universitet/Sjukhusfysikerutbildningen

    Author : Joanie Diha Guei; [2022]
    Keywords : Medicine and Health Sciences;

    Abstract : Introduction:The XenX is a small animal irradiation system that acquires high-resolution cone-beam tomography (CBCT) images of small animals and treats small animals with higher precision than medical linear accelerators. MuriSlice is a software for CBCT image reconstruction. READ MORE

  6. 20. Numerical simulation of acoustic wave propagation with a focus on modeling sediment layers and large domains

    University essay from Uppsala universitet/Avdelningen för beräkningsvetenskap

    Author : Elias Estensen; [2022]
    Keywords : Helmholtz; wave equation; acoustics; ocean acoustics; numerical analysis; computational science; finite differences; summation by parts; sbp; waveholtz; cylindrical coordinates; sediment layers; interface; super-grid; super grid; absorbing layer; Helmholtz; vågekvationen; akustik; undervattensakustik; numerisk analys; beräkningsvetenskap; finita differenser; summation by parts; sbp; cylindriska koordinater; waveholtz; sedimentskikt; interface; super-grid; absorberande lager;

    Abstract : In this report, we study how finite differences can be used to simulate acoustic wave propagation originating from a point source in the ocean using the Helmholtz equation. How to model sediment layers and the vast size of the ocean is studied in particular. READ MORE
