  1. 1. Cybersickness in a Virtual and Mixed Reality Flight Simulator With a Video See-Through Head-Mounted Display

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Christian K. K. Lindberg; [2023]
    Nyckelord :cybersickness; virtual reality; mixed reality; flight simulator; military; cybersjuka; virtuell verklighet; blandad verklighet; flygsimulator; militär;

    Sammanfattning : The Swedish Air Force Combat Simulation Centre (FLSC) is investigating how immersive technologies can be used with flight simulators. Cybersickness is sickness-like effects experienced when immersed in virtual environments using head-mounted displays. LÄS MER

  3. 2. Towards a setup for narrowband terahertz generation through difference-frequency mixing of chirped ultrashort pulses

    Master-uppsats, Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

    Författare :Isa Clementsson; [2023]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : Terahertz radiation is a useful tool for inducing lower-energy excitations in matter, where it can be used to cause structural changes through direct interaction with the crystal lattice. Sub-picosecond optical pulses can be used to generate intense broadband terahertz pulses through optical rectification in nonlinear crystals, reaching peak electric fields of several MV/m and conversion efficiencies as high as a few percent.

  4. 3. Assessment of Shoulder Biomechanics during Pull-up Techniques

    Master-uppsats, KTH/Medicinteknik och hälsosystem

    Författare :Mariah Sabioni; [2023]
    Nyckelord :strength training; biomechanics; motion analysis; shoulder; styrketräning; biomekanik; rörelseanalys; axel;

    Sammanfattning : CrossFit® has gained popularity as a functional training method that caters to individuals with varying levels of fitness, including those with little to no athletic background. Regardless, shoulders represent the highest injury rate in this sport, most frequently associated with pull-up variations. LÄS MER

  5. 4. Learning in physics with simulation : Students’ needs & perceptions of the interaction with Algodoo, and learning in physics

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Seyma Ikra Koyuncu; [2023]
    Nyckelord :computational thinking; stem; simulations; physics; modelling; digital tools; digital content; computational thinking; stem; simulering; fysik; modellering; digitalt verktyg; digitalt innehåll;

    Sammanfattning : Initiatives to implement computational thinking and science, technology, engineering & modelling into learning processes have been taken by many authorities worldwide, and in Sweden as well. The Swedish government made changes in the high school curriculum in order to develop student’s digital competence including programming which has been in force since June 2018 (Skolverket, 2018).

  7. 5. Multiple Fibre Bragg Grating Force Sensor

    Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)

    Författare :Felix Fritzén; [2023]
    Nyckelord :FBG force sensor; Fiber Bragg Grating force sensing; Fiber optic force sensor; Optical force sensing; Strain-based force sensing; Bragg wavelength shift; Force measurement using FBG; Fiber optic sensing technology; Fiber optic grating sensor;

    Sammanfattning : The purpose of this project is to explore the FBG (Fiber Bragg Grating) technology and create a force sensor. The result can be used as a basis for further projects.The project starts with force and strain measurements. The project then evolves to incorporate multiple FBG sensors. LÄS MER
