  2. 1. Evaluation of test cycles for freight locomotives

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

    Abstract : 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. READ MORE

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

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

    Abstract : 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. READ MORE

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

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

    Abstract : 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. READ MORE

  6. 4. Characterization and Correction of Analog-to-Digital Converters

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

    Abstract : 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. READ MORE

  7. 5. Fatigue of Heavy-Vehicle Engine Materials : Damage Mechanisms, Laboratory Experiments and Life Estimation

    Author : Viktor Norman; Johan Moverare; Peter Skoglund; Daniel Leidermark; Tilmann Beck; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Due to increasing demands on sustainability exerted by end-costumers and policy makers, heavyvehicle manufacturers are urged to increase the engine efficiency in order to reduce the exhaust gas emission. However, increasing the efficiency is also associated with an elevated fatigue rate of the materials constituting the engine parts, which consequently reduces the engine service life. READ MORE
