  1. 1. Sources of Variations in Error Sensitivity of Computer Systems

    Författare :Fatemeh Ayatolahi; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; error sensitivity; compiler optimization; transient fault; bit flipping; fault tolerance; fault injection;

    Sammanfattning : Technology scaling is reducing the reliability of integrated circuits. This makes it important to provide computers with mechanisms that can detect and correct hardware errors. This thesis deals with the problem of assessing the hardware error sensitivity of computer systems. LÄS MER

  3. 2. Space Geodesy Techniques: An Experimental and Theoretical Study of Antenna Related Error Sources

    Författare :R. T. Kenneth Jaldehag; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; reflector antennas; signal scattering; very long baseline interferometry VLBI ; signal multipath; space geodesy; GPS error sources; geodetic networks; Global Positioning System GPS ; postglacial rebound; choke-ring antennas;

    Sammanfattning : This thesis presents work associated with antenna related error sources, as well as antenna design, in space geodesy utilizing the techniques of Very-Long-Baseline Interferometry (VLBI) and the Global Positioning System (GPS). Geodetic VLBI uses large radio telescopes, often in global networks observing at least a few times per year. LÄS MER

  4. 3. Sources of preanalytical error in primary health care : implications for patient safety

    Författare :Johan Söderberg; Christine Brulin; Ewa Idvall; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; blood specimen collection; haemolysis; medical errors; phlebotomy; preanalytical; primary health care; quality indicators; quality of health care; questionnaires; specimen handling; Clinical chemistry; Klinisk kemi; medicin; Medicine;

    Sammanfattning : Background Venous blood tests constitute an important part in the diagnosis and treatment of patients. However, test results are often viewed as objective values rather than the end result of a complex process. This has clinical importance since most errors arise before the sample reaches the laboratory. LÄS MER

  5. 4. Faecal Calprotectin Diagnostics : Focus on Primary Care and Suspected Sources of Error

    Författare :Zlatica Rendek; Henrik Hjortswang; Magnus Falk; Ewa Grodzinsky; Stergios Kechagias; Mikael Lilja; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Calprotectin; Inflammatory bowel disease; Gastrointestinal disease; Primary health care; Non-steroidal anti-inflammatory agents; Proton pump inhibitors; Respiratory tract infection;

    Sammanfattning : Patients with gastrointestinal symptoms often present a diagnostic challenge for general practitioners. Faecal calprotectin (FC) is commonly used as a marker of intestinal inflammation and is useful for differentiating between inflammatory bowel disease (IBD) and irritable bowel syndrome (IBS), as well as for the follow-up of patients with IBD and monitoring treatment response.
