[Context and motivation] It is desirable that requirement engineering methods are reliable, that is, that methods can be repeated with the same results. Risk assessments methods, however, often have low reliability when they identify risk mitigations for a system based on expert judgement. [Question/problem] Our goal is to assess the reliability of an availability risk assessment method for tel...

The end-to-end response-time and delay analysis can verify timing requirements specified on vehicular distributed embedded systems without performing exhaustive testing. For this purpose, the timing requirements and constraints should be unambiguously translated among several models, methodologies and tools that are used at various abstraction levels and phases during the industrial development...

Prioritization of equipment is an important factor for decision making to optimize maintenance management in Reliability Centered Maintenance (RCM). Many factors must be considered as part of the prioritization of equipment for maintenance activities. Consequently, evaluation procedures involve several objectives and it is often necessary to compromise among conflicting tangible and intangible ...

This paper presents a new algorithm for detection of fixed-valued and random-valued impulses from images based on locally obtained statistics. By incorporating the rank-conditioned median (RCM) and center-weighted median (CWM) filters into an impulse noise detection framework, an adaptive mechanism is formed for effectively reducing impulse noise while preserving image details. The rank-conditi...

To improve the efficiency of reliability-centered maintenance (RCM) analysis, case-based reasoning (CBR), as a kind of artificial intelligence (AI) technology, was successfully introduced into RCM analysis process, and a framework for intelligent RCM analysis (IRCMA) was studied. The idea for IRCMA is based on the fact that the historical records of RCM analysis on similar items can be referenc...

In an approach towards the enantioselective total synthesis of the novel bioactive natural product Sch 642305, an unusual diastereoselection during the key RCM reaction, resulted in the synthesis of the 11-epi-isomer of Sch 642305.

In this project RCMs were applied to all these regions listed in Table 7.1 with the exception of the chest region. Examples of images with and without RCM are provided and discussed in this chapter. Appropriate and inappropriate use of factors that alter RCMs is also discussed, together with a comparison of RCM and other techniques used for dynamic range control. Specifically applied digital RC...

Hierarchies of diverse storage levels have been analyzed extensively for their ability to achieve both good performance and low cost. This position paper argues that we should view hierarchies also as a way to achieve both good reliability and low overhead. After discussing the design of a reliability hierarchy, we suggest two metrics to use in evaluating the overall reliability of a reliabilit...

For reliability-centered planning of preventive maintenance a three-stage combined outage and maintenance model of Markov-type is proposed in which each stage of system degradation is characterized by an individual outage and maintenance rate. By this model the restriction of Markov-theory to constant transition rates is overcome. Performing some simplifications the model can be used in reliabi...
