2. 1. 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. 2. 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. 3. Parameter identification in constitutive models with a posteriori error control and sensitivity assessment

   Author : Håkan Johansson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Sensitivity analysis; Goal-oriented error estimate; Calibration; Parameter identification;

   Abstract : In this thesis a framework for the calibration of constitutive models is presented. The framework involves theformulation of an optimization problem which is solved usingstrategies based on, essentially, Newton's method. READ MORE

6. 4. Sensitivity, Noise and Detection of Enzyme Inhibition in Progress Curves

   Author : Omar Gutierrez Arenas; Helena Danielson; Athel Cornish-Bowden; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; Progress curves; limit of detection; Z -factor; primary screening; enzyme inhibition; error structure; sensitivity analysis; High-throughput screning; Biokemi;

   Abstract : Starting with the development of an enzymatic assay, where an enzyme in solution hydrolysed a solid-phase bound peptide, a model for the kinetics of enzyme action was introduced. This model allowed the estimation of kinetic parameters and enzyme activity for a system that has the peculiarity of not being saturable with the substrate, but with the enzyme. READ MORE

7. 5. Contributions to generalized Wilcoxon rank tests

   Author : Marie-Louise Öhman; Hans Nyquist; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Censored data rank sum tests; Gehan s test; Generalized Wilcoxon test; Jackknifing; Two sample problem; Simulation; Survival data; Variance estimation; Influence function; Gross error sensitivity; Sensitivity curve; Misclassification; Statistics; computer and systems science; Statistik; data- och systemvetenskap; Statistics; statistik;

   Abstract : In unbalanced small sample size problems with right censorings, the variance estmators of linear rank statistics, may be biased. This is the case with the commonly applied variance estimators for the generalized Wilcoxon rank test statistics of Gehan and Prentice. READ MORE
