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.

5. 4. Fundamental Estimation and Detection Limits in Linear Non-Gaussian Systems

   Författare :Gustaf Hendeby; Fredrik Gustafsson; Niclas Bergman; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Estimation; Detection; Linear systems; Non-Gaussian; Limits; GLR; CRLB; Automatic control; Reglerteknik;

   Sammanfattning : Many methods used for estimation and detection consider only the mean and variance of the involved noise instead of the full noise descriptions. One reason for this is that the mathematics is often considerably simplified this way. LÄS MER

7. 5. Node-Level Fault Tolerance for Embedded Real-Time Systems

   Författare :Joakim Aidemark; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; fault injection; error recovery; reliability calculations; time redundancy; real-time kernels; error detection; analytical coverage estimation; distributed real-time systems;

   Sammanfattning : This thesis deals with cost-effective design and validation of fault tolerant distributed real-time systems. Such systems play an increasingly important role in embedded applications such as automotive and aerospace systems. LÄS MER
