  3. 2. 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

  4. 3. Study of the colonic mucus layer by mass spectrometry

    Författare :Sjoerd van der Post; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MUC2; mucin; intestine; proteomics; mass spectrometry;

    Sammanfattning : The mucus covering our internal mucosal surfaces is a part of the innate immune system, and the first line of defense against microbial challenges. The need of an efficient defense system is especially important in the lower parts of the digestive tract where the microbiota reaches its highest density. LÄS MER

  5. 4. Impacts of Speed Limits and Information Systems on Speed Choice from a Safety Perspective

    Författare :Ary P. Silvano; Haris N. Koutsopoulos; Karl-Lennart Bång; Haneen Farah; Johan Olstam; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; speed choice; urban; roads; speed limits; road characteristics; traffic safety; cooperative systems and warning messages;

    Sammanfattning : Driving a vehicle is considered a demanding task in a complex dynamic environment. For instance, driving a vehicle on urban roads, where motorized vehicles meet vulnerable road users (VRUs) creates a multifaceted environment with difficult trade-offs and interactions. LÄS MER

  7. 5. Prediction of the fatigue limit : accuracy of post-processing methods

    Författare :Sven Norberg; Mårten Olsson; Erland Johnson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Other engineering mechanics; Övrig teknisk mekanik;

    Sammanfattning : Several fatigue criteria were evaluated with experimental fatigue test data. The fatigue tests contained many different geometries with different degrees of stress concentration. It was concluded that the differences between the criteria were neglectable when compared to the differences between the specimens. LÄS MER
