We found a 12% error in the placement of intraperitoneal injections of mice with the one-man procedure of injection. With a two-man procedure, the incidence of error was consistently reduced to 1.2%.

Traditionally, fail-silent computers are implemented by using massive redundancy (hardware or software). In this research we investigate if it is possible to obtain a high degree of fail-silent behavior from a computer without hardware or software replication by using only simple behavior based error detection techniques. It is assumed that if the errors caused by a fault are detected in time i...

Soft errors caused by particles strike in combinational parts of digital circuits are a major concern in the design of reliable circuits. Several techniques have been presented to protect combinational logic and reduce the overall circuit Soft Error Rate (SER). Such techniques, however, typically come at the cost of significant area and performance overheads. This paper presents a low area and ...

Traditionally, the control logic of most microprocessors is not checked for soft errors due to great overheads while the remaining parts such as memory array and data path are often protected with error correcting codes. This paper presents a low-cost reliability enhancement scheme for the processors’ control logic. We classify control signals into static and dynamic control depending on their ...

This paper proposes an approach to software faults diagnosis in complex fault tolerant systems, encompassing the phases of error detection, fault location, and system recovery. Errors are detected in the first phase, exploiting the operating system support. Faults are identified during the location phase, through a machine learning based approach. Then, the best recovery action is triggered onc...

This paper shows improvement in the efficiency of self checking circuit with the use of exhaustive fault injection with analysis of property of circuit is shown. Experimental results from fault injection on a Reed-Solomon Decoder demonstrated that by observing the occurred errors and the correspondent detection module has been possible to reduce the number of detection module, while paying a sm...

ÐThe commercial offer concerning microkernel technology constitutes an attractive alternative for developing operating systems to suit a wide range of application domains. However, the integration of COTS microkernels into critical embedded computer systems is a problem for system developers, in particular due to the lack of objective data concerning their behavior in the presence of faults. Th...

A silicon independent C-Based model of the TTP/C protocol was implemented within the EU-founded project FIT. The C-based model is integrated in the C-Sim simulation environment. The main objective of this work is to verify whether the simulation model of the TTP/C protocol behaves in the presence of faults in the same way as the existing hardware prototype implementation. Thus, the experimental...

A better understanding of “human error” is needed to help overcome problems of people assuming they are to blame for their inability to use poorly designed technology. In order to investigate people's ability to recognize, and reflect on the causes of, particular types of errors, a problem solving environment was designed that allowed participants to verbally self-report erroneous and explorato...
