A state-based approach for on-line passive fault diagnosis in systems modelled as finite-state automata is presented. In this framework, the system and the diagnoser (the fault detection system) do not have to be initialized at the same time. Fhrthermore, no information about the state or even the condition (failure status) of the system before the initiation of diagnosis is required. The desig...

Many fault detection methods have been proposed for monitoring the health of various industrial systems. Characterizing the monitored signals is a prerequisite for selecting an appropriate detection method. However, fault detection methods tend to be decided with user's subjective knowledge or their familiarity with the method, rather than following a predefined selection rule. This study inves...

We describe fault tolerant routing of multi cast messages in mesh based wormhole switched multicom puters With the proposed techniques multiple convex faults can be tolerated The fault information is kept locally each fault free processor needs to know the status of the links incident on it only Furthermore the proposed tech niques are deadlock and livelock free and guarantee deliv ery of messa...

We describe fault-tolerant routing of multi-cast messages in mesh-based wormhole-switched multicom-puters. With the proposed techniques, multiple convex faults can be tolerated. The fault information is kept locally| each fault-free processor needs to know the status of the links incident on it only. Furthermore, the proposed techniques are deadlock-and livelock-free and guarantee delivery of m...

At un-signalised at-grade intersections or roundabouts, motorcyclists have to make a quick decision manoeuvre and avoid crash. Many studies show that risk-taking behaviour is the major cause of accidents in young motorcyclists. In this study, we analysed various factors are involved at intersections. Online questionnaires were distributed among university college students Islamabad Rawalpindi. ...

In this paper, we present an energy-efficient on-line diagnosis algorithm for cluster-based wireless sensor networks. It employs local comparisons of sensed data and dissemination of the decision made by the comparison results. Cluster-heads act as checkers for their associated cluster members. Redundant sensor nodes, as far as sensing coverage is concerned, are partially utilized to tolerate m...

Considering the development of power system automation and communications technology, this paper presents a fault diagnosis approach for power grid with information fusion based on multi-data resources which contain the switching-status data related to breakers and protection relays, and the continuous-time data derived from fault recorders. Fuzzy Petri nets and wavelet energy analysis are empl...

Strike-slip faults may be traced along thousands of kilometers, e.g., the San Andreas Fault (USA) or the North Anatolian Fault (Turkey). A closer look at such continental-scale strike faults reveals localized complexities in fault geometry, associated with fault segmentation, secondary faults and a change of related hazards. The North Anatolian Fault displays such complexities nearby the mega c...

    Condition Monitoring,   Oil Analysis, Wear Behavior,   Fuzzy Rule Based System   Maintenance , as a support function, plays an important role in manufacturing companies and operational organizations. In this paper, fuzzy rules used to interpret linguistic variables for determination of priorities. Using this approach, such verbal expressions, which cannot be explicitly analyzed or statistic...

Information security is an essential issue in communication system. Advance Encryption Standard (AES) is utilized as a part of many embedded applications to give data security. Different counter measures are present in AES against fault injection attacks. Plain text and key of 128-bit is given as an input to the system and encryption and decryption operations are performed. Flag error shows the...
