… work of a radar antenna for the radar system CARABAS. CARABAS is a long wave airborne ground radar that has been developed by SAAB Microwave Systems and will now be mounted on a small helicopter, Schweizer 300. The antenna should be able to fold up and down. When the radar is in …
En studie av Mocambiques demokratisering
Följande studie undersöker i vilken utsträckning parterna i trepartsförhållandet Upsala Nya Tidning, annonsör och läsare har överensstämmande åsikter om vad som är viktigt i relationen, samt hur väl de känner till varandras uppfattningar. Vi väljer att studera förhållandet ur …
This report investigates a possible solution to the problem with adapting wave powerplants to work in countries with tidal water. The wire connecting the buoy at the surface with the generator at the bottom needs to adjust to the varying water depth. Our solution to this problem …
