1. Design of an Array of Patch-elements With a Band-pass Frequency Selective Surface Hybrid Radome : Analysis and characterisation of a frequency selective surface and a phased array antenna
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : A circular polarised phased array antenna and a frequency selective hybrid radome are designed and evaluated. The antenna system is well suited as a part of a communication link between platforms with a 600 MHz bandwidth and a centre frequency of 5 GHz. LÄS MER
2. A measurement method for damping of drive shaft
H-uppsats,Sammanfattning : Sound in our society is beginning to be a health hazard in many places. This leads to legislation and recommendations by public authorities and governments. For a truck the sound pressure level should not exceed 80 dB(A) during a drive-by test set by international standards. LÄS MER
3. Influence of the Non-linear Effects in the Design of Viscous Dampers for Bridge Cables
Master-uppsats, KTH/Byggvetenskap; KTH/Skolan för arkitektur och samhällsbyggnad (ABE)Sammanfattning : In this master thesis the performance of external viscous dampers attached to cables in cable-stayed bridges have been studied. A comparison has been performed between a linear and a non-linear cable model. The comparison was carried out for two bridge cables, one from the Dubrovnik Bridge and the other from the Normandie Bridge. LÄS MER
