Software reliability growth models (SRGMs) are inadequate to assess the reliability of modern, heterogeneous, component–based software systems since these models treat the system as a black box and model its input/output behavior without looking into its internal structure. Development of techniques to assess the reliability of a component–based software system (which may be assembled from a va...

Risk assessment of urban infrastructure networks under natural and man-made hazards is often performed by repeated computational simulations based on random samples of hazard intensities and corresponding component status. This sampling-based approach may prevent near-real-time application of probabilistic methods to hazard mitigation of infrastructure networks and risk-informed decision suppor...

This paper presents a methodology for increasing audio watermark robustness. The method exploits the multidimensional nature of a stereo audio file, which provides two channels to hide data. By incorporating redundant information along both channels, the total number of errors due to attacks should be less than or equal to that produced by any one method alone.

Reliability allocation has an essential connection to design for reliability and is an important activity in the product design and development process. In determining the reliability of subsystems or components on the basis of goal reliability, attention must be paid to failure effect, failure information, and improvement opportunities based upon real potentials for reliability improvement. In...

The reliability analysis method and the allowable stress method were both applied in this study to determine design values of ultimate compression strength (UCS) of visually-graded 40 x 65 mm dimension Chinese larch lumber. A total of 784 lumber samples were tested on the static full-size compression strength, according to Chinese National Standards. The goodness-of-fit for the UCS distribution...

This paper describes a simulation method for reliability assessment of electrical distribution systems. The method has been implemented in the reliability assessment tool RADPOW which now is able to perform both analytical and simulation evaluations. The implemented method is validated by comparing results from application studies made for an electrical distribution system in the Stockholm area...
