Practical Thermal and Electrical Parameter Extraction Methods for Modelling HBT´s and their Applications in Power Amplifiers
Olavsbråten, Morten (Dr. ingeniøravhandling, 0809-103X; 2003:20, Doctoral thesis, 2003)A new practical technique for estimating the junction temperature and the thermal resistance of an HBT was developed. The technique estimates an interval for the junction temperature. The main assumption in the new technique ... -
Radio Tracking of Open Range Sheep: Methods for Radio Location in a Sub-GHz Base Station Network
Olsen, Snorre Haugstulen (Master thesis, 2014)This thesis aims to compare methods of radio location for the purpose of tracking sheep by using sub-GHz radio transceivers arranged in a base station network. Nearly 10% of free-grazing sheep in Norway are lost every year, ... -
Radiofrekvens-identifisering (RFID) til sporing av flybagasje
Sunde, Håvard (Master thesis, 2006)RFID har vært i bruk i over 20 år og er dermed ingen ny teknologi. Likevel har nye produksjonsmetoder og økt utbredelse først i det siste ført til at kostnadene har sunket til et nivå som gjør teknologien konkurransedyktig ... -
Slow Data Rate Communication in a Weak Signal Environment
