  1. 1. 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.

  2. 2. Error analysis of summation-by-parts formulations : Dispersion, transmission and accuracy

    Författare :Viktor Linders; Jan Nordström; Marco Kupiainen; Mark Carpenter; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : In this thesis we consider errors arising from finite difference operators on summation-by-parts (SBP) form, used in the discretisation of partial differential equations. The SBP operators are augmented with simultaneous-approximation-terms (SATs) to weakly impose boundary conditions. LÄS MER

  3. 3. Biomechanical methods and error analysis related to chronic musculoskeletal pain

    Författare :Fredrik Öhberg; Mats Djupsjöbacka; Åke Öberg; Högskolan i Gävle; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cervical spine; ensemble theory; error analysis; helical axis; kinematics; movement analysis; neural coding; pattern recognition; spike sorting; whiplash; Medical technology; Medicinsk teknik;

    Sammanfattning : Background Spinal pain is one of humanity’s most frequent complaints with high costs for the individual and society, and is commonly related to spinal disorders. There are many origins behind these disorders e.g., trauma, disc hernia or of other organic origins. LÄS MER

  4. 4. Error error lataa patteri : From language alternation to global multilingual repertoires in Finnish youth radio programs in Finland and Sweden

    Författare :Anu Muhonen; Jarmo Lainio; Mia Halonen; Stockholms universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; multilingualism; youth radio; discourse; identity; finska; Finnish;

    Sammanfattning : This PhD study explores multilingualism in Finnish language youth radio broadcasting, with interactional and ethnographic data from Sweden Finnish and Finnish youth radio broadcasting. The interactional data consist of audio recordings from radio programs, while the ethnographic data consist of observations, logbook notes and interviews. LÄS MER

  5. 5. On finite element schemes for Vlasov-Maxwell system and Schrödinger equation

    Författare :Christoffer Standar; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Nonlinear Schrödinger equation; Nitsche scheme; Streamline diffusion; Vlasov-Maxwell; a posteriori error analysis; a priori error analysis; hp-scheme; a posteriori error analysis;

    Sammanfattning : This thesis treats finite element schemes for two kind of problems, the Valsov-Maxwellsystem and the nonlinear Schrödinger equation. We study streamline diffusion schemes applied for numerical solution of the one and one-half dimensional relativistic Vlasov-Maxwell system. The study is made both in a priori and a posteriori settings. LÄS MER
