Applications of multi-state approach to the reliability evaluation of systems composed of independent components are considered. The main emphasis is on multi-state systems with degrading components because of the importance of such an approach in safety analysis, assessment and prediction, and analysing the effectiveness of operation processes of real technical systems. The results concerned w...

Distribution Reliability worth assessment is currently receiving considerable attention as it provides the opportunity to incorporate the cost or losses incurred by utility customers as a result of Power failure in the overall analysis of system costs & benefits. Distribution system reliability has acquired importance in these days, because the distribution system performance can directly affec...

In this paper, we present reliability analysis and comparison between on-chip communication architectures: dominant shared-bus AMBA and emerging network-on-chip (NoC); in the presence of single-event upsets (SEUs) using MPEG-2 video decoder as a case study. Employing SystemCbased fault simulations, reliability of the decoders is studied in terms of SEUs experienced in the computation cores and ...

A desired mesh architecture, based on connected-cycle modules, is constructed. To enhance the reliability, multiple bus sets and spare nodes are dynamically inserted to construct modular blocks. Two reconfiguration schemes are associated, and can eliminate the spare substitution domino effect. Simulations show that both schemes provide for increase in reliability over the interstitial redundanc...

In this paper, machine learning and geometric computer vision are combined for the purpose of automatic reading bus line numbers with a smart phone. This can prove very useful to improve the autonomy of visually impaired people in urban scenarios. The problem is a challenging one, since standard geometric image matching methods fail due to the abundance of distractors, occlusions, illumination ...

This study presents optimal placement of voltage sag monitors based on new Sag Occurrence Index (SOI) which ensures observability even in case of monitor failure or line outages. Multiple solutions for optimal placement of voltage sag monitors for voltage sag detection have been obtained by genetic algorithm approach such that observability of the whole system is guaranteed. A new Sag Occurrenc...

In order to improve service reliability, many transit agencies add a significant amount of slack in the schedule. However, too much slack in the schedule reduces service frequency. We study the problem of determining the optimal slack that minimizes the passengers’ expected waiting times under schedule-based control. By associating with a D/G/c queue model, we show that the system is stable if ...

Car reverse image is transmitted by information bus. Because of the bad electromagnetic environment of the engine compartment, car’s information bus sometime will be blocked or not real-time, which can lead to the uncertainty of information transmission, and will cause the risks of security and reliability of the transmitted network. A GHM multi-wavelet is adopted by this paper to restore the i...

Electricity grids are critical infrastructures. They are credible targets of active (e.g., terrorist) attacks since their disruption may lead to sizable losses economically and in human lives. It is thus crucial to develop decision support that can guide administrators in deploying defense resources for system security and reliability. Prior work on the defense of critical infrastructures has t...

Distributed factory automation systems benefit from field-busses which, in general, provide support for reliable and timely communication. These field-busses, however, provide rather low level communication objects and their features regarding quality aspects of communication are difficult to assess and use for applications. The paper presents COSMIC (Cooperating Smart devices), a middleware ar...
