  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

    Sammanfattning : Information technology evidence consists of a mix of representations of various applications of digital electronic equipment, and can be brought to the fore in all contexts that result in legal decisions. The occurrence of such evidence in legal proceedings, and other legal decision-making, is a phenomenon previously not researched within legal science in Sweden. 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. Aerodynamics of Vertical Axis Wind Turbines : Development of Simulation Tools and Experiments

    Författare :Eduard Dyachuk; Hans Bernhoff; Sandra Eriksson; Anders Goude; Mac Gaunaa; Uppsala universitet; []
    Nyckelord :wind power; vertical axis turbine; H-rotor; simulations; streamtube model; vortex model; dynamic stall; measurements; blade; force; Engineering Science with specialization in Science of Electricity; Teknisk fysik med inriktning mot elektricitetslära;

    Sammanfattning : This thesis combines measurements with the development of simulation tools for vertical axis wind turbines (VAWT). Numerical models of aerodynamic blade forces are developed and validated against experiments. The studies were made on VAWTs which were operated at open sites. LÄS MER

  7. 5. Investigation and calibration of pulsed time-of-flight terrestrial laser scanners

    Författare :Yuriy Reshetyuk; Lars E. Sjöberg; Stig-Göran Mårtensson; KTH; []
    Nyckelord :terrestrial laser scanning; error sources; calibration; coordinate precision accuracy;

    Sammanfattning : This thesis has two aims. The first one is the investigation and analysis of the errors occurring in the measurements with pulsed time-of-flight (TOF) terrestrial laser scanners (TLS). A good understanding of the error sources and the relationships between them is necessary to secure the data accuracy. LÄS MER
