  1. 1. Estimation and detection of transmission line characteristics in the copper access network

    Author : Fredrik Lindqvist; Institutionen för elektro- och informationsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Digital subscriber line; DSL; line qualification; twisted-pair line; copper access network; cable modeling; crosstalk channel estimation; estimation; detection;

    Abstract : 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. READ MORE

  2. 2. Otherness and disease in Reunion : The politicisation of the 2005 to 2007 chikungunya epidemic

    Author : Karine Aasgaard Jansen; Tove Ingebjørg Fjell; Astrid Blystad; Line Alice Ytrehus; Pamila Gupta; University of Bergen; []

    Abstract : 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. READ MORE

  3. 3. Some studies on metamaterial transmission lines and their applications

    Author : Xin Hu; Sailing He; Ferran Martin; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; metamaterial; transmission line theory; composite right left-handed transmission line; diplexer; coupler; balun; interdigital capacitor; split ring resonator; Electrical engineering; Elektroteknik;

    Abstract : 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. READ MORE

  4. 4. Data Driven Condition Monitoring for Transmission and Axles

    Author : Elisabeth Källström; John Lindström; Magnus Karlberg; Jiri Tuma; Luleå tekniska universitet; []

    Abstract : 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. READ MORE

  5. 5. Computation of EMC Properties of Slots and Printed Circuit Boards

    Author : Jan Carlsson; Chalmers University of Technology; []
    Keywords : corrugations; crosstalk; FDTD; spectral domain; EFIE; chokes; Finite Difference Method; printed circuit board; transmission line network; EMC analysis; PCB; transmission line theory; radiated emission; Method of moments; MM; MoM; electric field integral equation; soft and hard surfaces; slot; radiated susceptibility;

    Abstract : This thesis deals with the numerical solution of electromagnetic compatibility (EMC) problems for electronic systems, such as radiated emission, susceptibility and crosstalk on printed circuit boards and transmission through slots. The analysis of printed circuit boards is done by using an electric field integral equation (EFIE) expressed in the frequency domain, which is solved by using the method of moments. READ MORE
