Wood utility poles are central to many electrical distribution networks, yet there have been no published studies to determine what operational characteristics of utility poles are indicative of decay in the field. We apply survival analysis to a database of more than 17 000 utility poles in the Pacific Northwest, and find that larger circumference poles decay sooner, that Douglas fir poles...
The paper concerns credibility of construction methods for affect-annotated lexicons, specifically a web questionnaire is explored and evaluated. Web-based surveys are susceptible to some risks, which might influence credibility of the results, as some participants might perform random clicks or intentionally falsify the responses. The paper explores the risks and proposes some strategies to reduce...
This paper aims to present a study on knowledge management. We develop decision-support mechanisms hybridizing statistical and cognitive experience feedback to perform risk assessments on critical areas of a system. We propose an approach for combining expert opinion and statistics by using belief functions and by processing the combined knowledge in a directed evidential network to provide a risk...
It is very important to assess the impact of risk on decisions during the development of products or systems. The traditional way tends to make predictions quantitatively for the product design and manufacture phases but not to extend them to the service phase. This research presents a novel application of simulation to modeling the whole life cycle of a product and imitating the behavior and characteristics...
If Grid computing is to experience widespread commercial adoption, then incorporating risk assessment and management techniques is essential,both during negotiation between service provider and service requester and during run-time. This paper focuses on the role of a resource broker in this context. Specifically, an approach to evaluating the reliability of risk information received from resource...
With the development of IT, kinds of information systems and software have been applied in the audited enterprises. That means the audited enterprises have set up their computer-based information-processing environment. In such environment, the uncertainty factors of the certified public accountants (CPA) audit are increasing and the audit risk is enhanced. It is more suitable for the audit risk factors...

Accelerated by the rapid deployment of distributed systems and the Internet, online collaboration and information sharing are pervasive in enterprise computing environment. With regard to the requirements of online collaboration and information sharing, authentication information needs flexible manipulation to facilitate federation across trust domains. To achieve identity federation for federated...
