Faults in computer networks may result in millions of dollars in cost. Faults in a network need to be localized and repaired to keep the health of the network. Fault management systems are used to keep today’s complex networks running without significant cost, either by using active techniques or passive techniques. In this paper, we propose a novel approach based on imperialist competitive alg...

For constrained devices, elliptic curve cryptography (ECC) is an attractive choice because it achieves the same level of security with a much smaller key size in comparison with other schemes such as those that are based on integer factorization or discrete logarithm. For security reasons, especially to provide resistance against fault-based attacks, it is very important to verify the correctne...

Combining a simplified on-board turbo-shaft model with sensor fault diagnostic logic, a model-based sensor fault diagnosis method is proposed. The existing fault diagnosis method for turbo-shaft engine key sensors is mainly based on a double redundancies technique, and this can't be satisfied in some occasions as lack of judgment. The simplified on-board model provides the analytical third chan...

in this paper, in order to increase the efficiency, to reduce the cost and to prevent the failures of wind turbines, which lead to an extensive break down, a robust fault diagnosis system is proposed for v47/660kw wind turbine operated in manjil wind farm, gilan province, iran. according to the acquired data from iran wind turbine industry, common faults of the wind turbine such as sensor fault...

ABSTRACT This paper describes how a model-based, feedforward control scheme can improve control performance over traditional PID and detect faults in the controlled process. The scheme uses static simulation models of the system under control to generate feedforward control action, which supplements a conventional PID feedback loop. The feedforward action reduces the effect of plant non-lineari...

The synchronization dynamics of grid-connected power converters are known to have a tremendous impact on transient stability and fault ride-through performance under grid faults. Up till now, the modeling converter stability, which has paved way for numerous enhanced control methods, is developed around assumption that symmetrical. However, this rarely case. Moreover, codes require dual-sequenc...

We describe the parallelization of sequential circuit test generation on an Ethernet-connected network of SUN workstations. We use the observations of the previous work to execute the program in two phases. All processors simultaneously run the test generation program, Gentest. In the rst phase, the fault list is equally divided among processors, each of which derives tests for targets from its...
