1. Estimation and detection of transmission line characteristics in the copper access network
Sammanfattning : The copper access-network operators face the challenge of developing and maintaining cost-effective digital subscriber line (DSL) services that are competitive to other broadband access technologies. The way forward is dictated by the demand of ever increasing data rates on the twisted-pair copper lines. LÄS MER
2. Otherness and disease in Reunion : The politicisation of the 2005 to 2007 chikungunya epidemic
Sammanfattning : In this dissertation I investigate how decolonisation through inclusion instead of independence has affected processes of othering, and reactions to being othered. By othering I mean discursive colonial practices described by post-colonial theories, in which racial and cultural difference is produced as inferior vis-à-vis the “superior” West. LÄS MER
3. Some studies on metamaterial transmission lines and their applications
Sammanfattning : This thesis focuses mostly on investigating different potential applications of meta-transmission line (TL), particularly composite right/left handed (CRLH) TL, and analyzing some new phenomena and applications of meta-TL, mostly left-handed (LH) TL. Realization principle will also be studied. LÄS MER
4. Distance Protection of Transmission Lines with High Levels of Series Compensation : A study on frequency and time domain communication independent distance protection for series compensated lines
Sammanfattning : Series capacitors are used in electric transmission lines to increase their power transfer capacity. They compensate for the inductive reactance of the line. They offer a useful alternative to building new lines, in view of economic and environmental constraints. LÄS MER
5. Data Driven Condition Monitoring for Transmission and Axles
Sammanfattning : As the requirements to improve up-time and thus to reduce costly down-time con-tinuously increases, the construction equipment business focuses on more and newways to increase ability and sensitivity of early fault detection of critical compo-nents and parts in order to prevent failure. Failure of critical components in theheavy duty machine may lead to unnecessary stops and expensive downtime. LÄS MER
