  2. 16. Sources of Variations in Error Sensitivity of Computer Systems

    Author : Fatemeh Ayatolahi; Chalmers tekniska högskola; []
    Keywords : 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;

    Abstract : 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. READ MORE

  4. 17. Towards Accurate Estimation of Error Sensitivity in Computer Systems

    Author : Fatemeh Ayatolahi; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; silent data corruption; error sensitivity; fault injection; soft errors;

    Abstract : Fault injection is an increasingly important method for assessing, measuringand observing the system-level impact of hardware and software faults in computer systems. This thesis presents the results of a series of experimental studies in which fault injection was used to investigate the impact of bit-flip errors on program execution. READ MORE

  5. 18. Gearbox noise : Correlation with transmission error and influence of bearing preload

    Author : Mats Åkerblom; Sören Andersson; D. Houser; KTH; []
    Keywords : gear; gearbox; noise; vibration; transmission error; bearing preload; Mechanical engineering; Maskinteknik;

    Abstract : The five appended papers all deal with gearbox noise and vibration. The first paper presents a review of previously published literature on gearbox noise and vibration. The second paper describes a test rig that was specially designed and built for noise testing of gears. READ MORE

  6. 19. Language Modelling and Error Handling in Spoken Dialogue Systems

    Author : Genevieve Gorrell; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Language Modelling; Spoken Dialogue Systems; Error Handling; Computer science; Datavetenskap;

    Abstract : Language modelling for speech recognition is an area of research currently divided between two main approaches: stochastic and grammar-based approaches are each being differently preferred for their respective strengths and weaknesses. At the same time, dialogue systems researchers are becoming aware of the potential value of handling recognition failures better to improve the user experience. READ MORE

  7. 20. Hardware and Software Mechanisms for Control Flow Checking

    Author : Ghassem Miremadi; Chalmers tekniska högskola; []
    Keywords : 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;

    Abstract : 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. READ MORE
