1. Jämförelse av justerat IOP erhållet av Topcon TRK-2P med och utan mjuka kontaktlinser på ögat : En kvantitativ studie
Kandidat-uppsats, Linnéuniversitetet/Institutionen för medicin och optometri (MEO)Sammanfattning : Syfte: Syftet med studien var att ta reda på om non contact tonometern Topcon TRK-2P med justerat IOP kan kompensera för den extra tjockleken som fås av en kontaktlins på ögat. Kan maskinen fortfarande ge ett överensstämmande resultat jämfört med IOP utan en kontaktlins på ögat? Metod: 30 personer deltog och medelvärdet på åldern var 24,1 ± 6,9 år. LÄS MER
2. Void Evolution and Cosmic Star Formation
Kandidat-uppsats, Uppsala universitet/Institutionen för fysik och astronomiSammanfattning : The rate at which stars have formed throughout the history of theuniverse is not constant, it started out slow, increased until around redshift ∼ 2 when it reversed and became slower again. The reason for this behaviour is still being investigated with various models and simulations usually based upon dark matter halos. LÄS MER
3. Modelling Gas Flow Behaviour in Gas Atomizer
Master-uppsats, KTH/MaterialvetenskapSammanfattning : Gas atomization is regarded as a reliable method for creating high-quality metal powders from molten metal. The liquid metal is fed into the chamber as a free-falling stream through a nozzle, where it is impinged by high-velocity gas jets, causing degeneration and production of metal droplets, which solidify to create metal powders.

4. Modelling of Corneal Surface - A Method for Reconstruction of Corneal Surface in a Wearable Eye Tracking Device
Master-uppsats, KTH/Matematik (Avd.)Sammanfattning : We investigate a method for reconstructing the anterior corneal surface using wearable eye tracking devices. The presented method assumes that the four reflection points from two light sources viewed by two cameras lie on a locally spherical surface of a cornea. LÄS MER
5. Antenna Implants and Feasibility of Performance Limitations : AStudy of Radiation Efficiency on Electrically Small Antenna Implants with Finite Conductivity and Size
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : Antenna implants are used to establish a telemetry link to enable wireless data transfer, suitable for telemedicine and other medical applications. Inbody environments with water-based tissues lead to severe power absorption, making signal strength and radiation efficiency challenging yet central performance aspects of antenna implants. LÄS MER
