  1. 1. Vardagens landskap : lokala perspektiv på bronsålderns materiella kultur

    Författare :Peter Skoglund; Arkeologi; []
    Nyckelord :HUMANIORA; HUMANITIES; South Swedish higland; Fossil arable land; Rock-carving; Monument; Cultural heritage; Local perspective; Regional diversity; Praxis theory; Material culture; Landscape archaeology; Archaeology; Arkeologi;

    Sammanfattning : In the thesis the author discusses how materiel culture changed when it was incorporated into a local society. The discussion is based on graves, rock carvings and bronze items in south Scandinavia during the periods Late Neolithic and Bronze Age, 2350-500 BC. The thesis? starting point is a praxis perspective. LÄS MER

  3. 2. Evaluation of test cycles for freight locomotives

    Författare :Mattias Skoglund; Stefan Östlund; Peter Thelin; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; duty cycles; test cycles; diesel locomotives; locomotive emissions; dual modes; hybrid systems;

    Sammanfattning : Diesel locomotives provide versatility to the railway system as they do not depend on electric feeding. Worldwide they constitute important parts of locomotive fleets used for various tasks such as mainline services, shunting and terminal operations. The main drawbacks are emissions of CO2, NOx and other pollutants. LÄS MER

  4. 3. Electron-Impact Liquid-Jet Water-Window X-ray Sources

    Författare :Peter Anders Skoglund Lindberg; Hans M. Hertz; Oscar Tjernberg; KTH; []
    Nyckelord :TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : This Thesis describes the development and characterization of a soft x-ray liquidjet-anode electron-impact source. With a water-jet target the primary emission is the O Kα line at 525 eV. This is close to the lower edge of the water-window, a spectral region lacking simple laboratory sources. LÄS MER

  5. 4. On Performance Analysis of Retransmission Schemes with Fading Channels

    Författare :Peter Larsson; Lars Kildehøj Rasmussen; Mikael Skoglund; Leszek Szczecinsky; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Automatic repeat request; ARQ; hybrid-arq; retransmission schemes; Telecommunication; Telekommunikation;

    Sammanfattning : Future wireless communication systems and services bring increased performance demands, with respect to data-rate(s), reliable communication, (stochastic) real-time guarantees, and more. In this context, not only new communication schemes are needed, but also more capable performance analysis methods are essential. LÄS MER

  7. 5. Characterization and Correction of Analog-to-Digital Converters

    Författare :Henrik Lundin; Peter Händel; Mikael Skoglund; Paolo Carbone; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; analog-to-digital converter; ADC; correction; post-correction; look-up table; characterization; calibration; Signal processing; Signalbehandling;

    Sammanfattning : Denna avhandling behandlar analog-digitalomvandling. I synnerhet behandlas postkorrektion av analog-digitalomvandlare (A/D-omvandlare). A/D-omvandlare är i praktiken behäftade med vissa fel som i sin tur ger upphov till distorsion i omvandlarens utsignal. LÄS MER
