    Sammanfattning : A significant level of research is currently being carried out in the development of driver support systems as they are expected to play a key role in minimizing road vehicle accidents and creating a safe driving environment under harsh weather conditions. However, the performance of some components used by existing driver support systems like LIDAR and visual cameras are affected by extreme weather conditions such as heavy rain fall and snow. LÄS MER

  3. 2. Accelerated aging of thick glass second surface silvered reflectors under sandstorm conditions

    Master-uppsats, Maskinteknik

    Författare :Simon Caron; [2011]
    Nyckelord :Accelerated aging; Sandstorm simulation; Solar Energy;

    Sammanfattning : Concentrated solar power systems are expected to be sited in desert locations where the direct normal irradiation is above 1800 kWh/m2.year. These systems include large solar collector assemblies, which account for a significant share of the investment cost. LÄS MER

  4. 3. Självsanerande ytbeläggning i nanostruktur : Är det möjligt att applicera på elektrooptiska sensorer och till vilken nytta?

    Kandidat-uppsats, Försvarshögskolan

    Sammanfattning : Då marina enheter numera deltar i internationella missioner, kommer den nya miljön som enheterna opererar i att påverka bland annat deras sensorer. Den här studien avhandlar några av de nu framtagna självsanerande ytbeläggningarna och ger en presentation av hur de fungerar på några marina elektrooptiska sensorers yttersta linser. LÄS MER
