  2. 1. Switch-Level Fault Simulation Based on Local Algorithms

    Author : Peter Dahlgren; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; switch level; fault propagation; fault simulation; physical fault injection; short faults; stuck-at faults; fault modeling; transients; self-checking circuits; multiple dominance;

    Abstract : The presence of realistic faults in CMOS networks, such as shorts and opens, frequently gives rise to intermediate voltage values. At the switch level, these values result in undetermined logic states (X) which are likely to propagate to the outputs, causing uncertainty in the estimation of test set efficiency. READ MORE

  4. 2. Fault Injection for Studying Error Behavior and Validation of Error Detecting Mechanisms

    Author : Marcus Rimén; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; concurrent error detection; functional error model; control flow error; error detection coverage; permanent faults; data error; error detection latency; simulation-based fault injection; transient faults; physical fault injection; dependability evaluation;

    Abstract : This thesis deals with the design and validation of low-cost error detecting mechanisms that can be used to implement self-checking computers. The research objectives of the thesis are three-fold: (i) to investigate and develop a simulation-based fault injection technique that can be used on a wide range of VHDL simulation models, (ii) to investigate error propagation mechanisms in microprocessors in order to understand how to design low-cost error detecting mechanisms and (iii) to design and validate error detecting mechanisms.

  5. 3. Fault Simulation and Physical Fault Injection Applied to MOS Transistor Networks

    Author : Peter Lidén; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Detailed information on a system's behavior in the presence of faults is often vital. It may be used to grade or construct tests for the efficient detection of faults or to increase confidence in high-reliable systems. READ MORE

  6. 4. Analysis and Synthesis of Boolean Networks

    Author : Ming Liu; Elena Dubrova; Radomir Stankovic; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : In this thesis, we present techniques and algorithms for analysis and synthesis of synchronous Boolean and multiple-valued networks.Synchronous Boolean and multiple-valued networks are a discrete-space discrete-time model of gene regulatory networks. READ MORE

  7. 5. Diagnosis and Supervision of Industrial Gas Turbines

    Author : Emil Larsson; Jan Åslund; Erik Frisk; Lars Eriksson; Mattias Henriksson; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Monitoring of industrial gas turbines is of vital importance, since it gives valuable information for the customer about maintenance, performance, and process health. The performance of an industrial gas turbine degrades gradually due to factors such as environment air pollution, fuel content, and ageing to mention some of the degradation factors. READ MORE
