  1. 11. Fault Injection for Studying Error Behavior and Validation of Error Detecting Mechanisms

    Författare :Marcus Rimén; Chalmers tekniska högskola; []
    Nyckelord :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;

    Sammanfattning : 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.

  3. 12. Hardware and Software Mechanisms for Control Flow Checking

    Författare :Ghassem Miremadi; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; fault tolerance; error detection latency; signature monitoring; watchdog processor; dependability evaluation; transient faults; physical fault injection; concurrent error detection; control flow checking; error detection coverage;

    Sammanfattning : The improvement of dependability in computing systems requires the evaluation of fault tolerance mechanisms such as error detection, error recovery and reconfiguration. Central to this thesis is an experimental evaluation of several hardware and/or software implemented mechanisms for the concurrent detection of control flow errors. LÄS MER

  5. 14. An Experimental Study of Fluid Dynamics and Mixing in Bubbly Gas-Liquid Flow Systems

    Författare :Jafar Sadegh Moghaddas; Livsmedelsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bubbly flow; PLIF; Two-phase flow; PIV; Gases; plasmas; Gaser; fluid dynamics; fluiddynamik; plasma; Mixing;

    Sammanfattning : In the present project, a new experimental method enabling Planar Laser-Induced Fluorescence (PLIF) measurements in bubbly gas-liquid flows is presented. Due to reflection and refraction of the laser light, the bubbles will cause an uneven and unknown distribution of light intensity in the measurement plane. LÄS MER

  7. 15. In-Nozzle Flow and Primary Breakup Investigations of Marine Two-Stroke Diesel Engine Injectors

    Författare :Reto Balz; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; in-nozzle flow; fuel injection; primary breakup; cavitation;

    Sammanfattning : This thesis will focus on the experimental studies of in-nozzle flow and primary breakup of pressure-atomized fuel sprays as used in large marine two-stroke Diesel engines. To further increase the efficiency of large marine two-stroke Diesel engines, a better understanding of the fuel spray atomization process is necessary. LÄS MER
