  1. 1. Hand Gesture based Telemedicine enabled by Mobile VR

    University essay from Linnéuniversitetet/Institutionen för datavetenskap och medieteknik (DM)

    Author : Sofia Kiriaki Vulgari; [2019]
    Keywords : Virtual Reality; Hand Gestures; Virtual Environment; Telemedicine; Mobile VR; Multi User;

    Abstract : Virtual Reality (VR) is a highly evolving domain and is used in anincreasing number of areas in today's society. Among the technologiesassociated with VR and especially mobile VR, is hand tracking and handgesture recognition. READ MORE

  2. 2. Studies of Light Hyperon Decay Parameters

    University essay from Uppsala universitet/Kärnfysik

    Author : Annele Heikkilä; [2019]
    Keywords : Hadron Physics; Hyperon; CP symmetry; Monte Carlo simulations; BESIII;

    Abstract : A basic assumption in fundamental physics is that equal amounts of matter and antimatter were created after the Big Bang. When particles and antiparticles collide, they annihilate, i.e. disappear and produce photons. READ MORE

  3. 3. Geant4 Simulations of Hadron Therapy and Refinement of User Interface

    University essay from KTH/Medicinteknik och hälsosystem; KTH/Medicinteknik och hälsosystem

    Author : Emil Ekelund; David Fogelberg Skoglösa; [2019]
    Keywords : Geant4; Hadron Therapy; Bragg Peak; Monte Carlo; ROOT;

    Abstract : Radiotherapy is one of the most used methods for treating cancer and the most common way to execute such treatments is to irradiate tumors with high energy photons. This can damage healthy tissue along the irradiation line. READ MORE

  4. 4. Designing radiation protection for a linear accelerator : using Monte carlo-simulations

    University essay from Umeå universitet/Institutionen för fysik

    Author : Jonatan Lindahl; [2019]
    Keywords : linac; linear accelerator; accelerator; mega voltage photons; spectra determination; high energy photons; Monte carlo; simulations; radiation transport; dose; radiation; radiation protection;

    Abstract : The department of Radiation Sciences at Umeå University has obtained an old linear accelerator, intended for educational purposes. The goal of this thesis was to find proper reinforced radiation protection in an intended bunker (a room with thick concrete walls), to ensure that the radiation outside the bunker falls within acceptable levels.

  5. 5. Asymptotic Symmetries and Faddeev-Kulish states in QED and Gravity

    University essay from Stockholms universitet/Fysikum

    Author : David Gaharia; [2019]
    Keywords : Faddeev-Kulish; BMS; Bondi-Metzner-Sachs; Asymptotic Symmetries; Asymptotic States; Wilson Lines; Infrared Divergence; Bloch-Nordsieck; Large Gauge Transformations; Fock; QED; Quantum Electrodynamics; Perturbative Quantum Gravity; PQG; U 1 ; Transformations; Mandelstam Quantization;

    Abstract : When calculating scattering amplitudes in gauge and gravitational theories one encounters infrared (IR) divergences associated with massless fields. These are known to be artifacts of constructing a quantum field theory starting with free fields, and the assumption that in the asymptotic limit (i.e. READ MORE
