  2. 1. Assessment and Comparison of Physical Fault Injection Techniques

    Author : Peter Folkesson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; fault tolerance; concurrent error detection; dependability; coverage; fault injection; experimental validation; boundary scan;

    Abstract : This thesis deals with the problem of validating and estimating the effectiveness of error handling mechanisms in computer systems. The main contribution is an assessment of the effectiveness and usefulness of several physical fault injection techniques. READ MORE

  4. 2. On Impact and Tolerance of Data Errors with Varied Duration in Microprocessors

    Author : Örjan Askerdal; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; fault injection; dependability; error propagation analysis; fault tolerance; error effect analysis;

    Abstract : The evolution of high-performance and low-cost microprocessors has led to their almost pervasive usage in embedded systems such as automotive electronics, smart gadgets, communication devices, etc. These mass-market products, when deployed in safety-critical systems, require safe services albeit at low recurring costs.

  5. 3. Measuring the Impact of Hardware Errors in Computer Systems

    Author : Behrooz Sangchoolie; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Sources of Variation; Fault Injection; Dependability Assessment; Microprocessor Faults; Hardware Error Sensitivity;

    Abstract : This thesis addresses the problem of measuring hardware error sensitivity of computer systems. Hardware error sensitivity is the probability that a hardware error will result in an erroneous output. READ MORE

  6. 4. Dependability analysis of military aircraft fleet performance in a lifecycle perspective

    Author : Jan Block; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Drift och underhållsteknik; Operation and Maintenance;

    Abstract : Today's highly advanced technological flying platforms, such as aircraft, helicopters and Unmanned Air Vehicles (UAVs), are characterised by a high degree of complexity. Simultaneously, they are used in different operational and mission profiles, and also in multiple operational environments and geographical settings. READ MORE

  7. 5. A Software Profiling Methodology for Design and Assessment of Dependable Software

    Author : Martin Hiller; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The advent of computerized consumer products, such as for example automobiles, mobile systems, etc., has produced a large increase in the need for dependable (or robust) systems. As cost is a relevant issue for such systems, the cost of dependability has to be kept low. READ MORE
